1.0 Substrate Preparation

General Substrate Conditions

Preparation of the roof is the duty of the installer, who is tasked with identifying and rectifying all conditions outlined in this section.

Inspect the base surfaces where new roofing will be applied. NanoTech Materials requires an adhesion test to be performed during the

inspection of all roof remediation candidates.

Do not commence the installation of the NanoTech Materials coating system until its compatibility and adhesion have been confirmed

through test patches, all preparatory tasks have been completed, and any unsatisfactory conditions have been addressed.

Ensure proper water drainage from the roof. The roof should not retain water for over 48 hours following the cessation of precipitation.

NanoTech Materials defines “ponding” as water that remains on the roof surface for more than 48 hours after the end of precipitation. Ponding may also occur due to other water sources, such as improperly routed air conditioning condensate and steam condensate lines.

Shield nearby surfaces that will not receive the coating.
Refrain from applying liquid-applied roofing products to surfaces deemed unsuitable by NanoTech Materials or under adverse

environmental conditions, as defined in individual spec sheets.

The roof must be clean, dry, and devoid of any debris prior to the application of any liquid-applied products. NanoTech Materials liquid-

applied roofing products are not intended for use on substrates subject to heavy foot traffic. In cases where substantial foot traffic is anticipated, utilize a rooftop walkway system approved by NanoTech Materials. Always contact NanoTech Material’s Technical Sales Support Services at (888) 296-6266 for questions. NanoTech must approve exposure to any chemicals or products such as those used to clean mechanical equipment.

Proper Preparation

For the correct application of the coating, it’s crucial to thoroughly clean the existing roof. All accumulated dust, chalky residue, exposed bitumen, greases, oils, and any other loose materials must be eliminated before applying the coating. It is imperative to avoid solvent-based cleaners when preparing a roofing substrate for the application of the NanoTech Materials Cool Roof Coat. A pressure washer is the only approved cleaning mechanism. Should pressure washing fail to fully clean the roof, contact the Nanotech Materials support team prior to applying a cleaning agent, to check for chemical compatibility with the coating. Exercise caution during pressure washing to maintain the integrity of the existing roof covering and to prevent damage, particularly to adhered seam areas. The roof should be completely dry before initiating any priming or coating process. Depending on the results of the adhesion test, the use of a primer might be necessary. Any essential repairs to the roof or flashings should be carried out and given sufficient time to cure where needed. For more detailed information on roof preparation, consult specific sections of this manual.

Existing Roof Substrate Inspection

The roof surface shall be inspected for blisters, ridges, mole runs, unadhered membranes, or in the case of metal roofing rust and pitted metal. All surface defects must be corrected to industry standards as established by the manufacturer or NRCA Repair Manual. Other sources may be submitted for NanoTech’s approval. Underneath membrane roofing systems, there is usually a layer of insulation. Should the roof have experienced leaks in the past, it’s possible that wet insulation may exist within the current roofing structure. Any damp roof insulation must be identified, removed, and replaced before the coating process. While some sections of wet insulation might be detectable simply by feeling the surface as you walk, conducting a moisture survey or core sample analysis is advisable for a more precise identification of these areas. Metal roofs are typically mounted over a solid roofing deck or above purlins and insulation. Inspecting the lower side of the roof deck can help in spotting regions of wet insulation, a deteriorated deck, or other damages that require attention and repair before proceeding with the coating.

Moisture Survey

The contractor is responsible for ensuring there is no subsurface moisture present and any insulation remains dimensionally sound. A suitable moisture survey method is to be approved by NanoTech and all moisture identified removed. Additionally, an underside inspection is to be conducted to ensure there are no visible defects or structural concerns.

Repair Standards

Challenges identified from the inspections described above will be corrected. The section outlined below provides general corrective

NanoTech Materials, Inc. | NanoTechMaterials.com | (888) 296-6266 procedures and are not necessarily comprehensive or complete.

Adhesion Testing

Adhesion testing is typically carried out to ascertain the compatibility of a base surface for the application of a liquid- applied coating system. NanoTech Materials requires an adhesion test to be performed on all roofing substrates prior to the application of the coating. The use of NanoTech Primer is required for any substrate which fails an adhesion test. The adhesion test must be repeated once the primer has been applied. If the adhesion test fails a second time, the application is to be rejected. When conducting adhesion tests:

The test patches should be clearly marked and photographed to record the outcomes of the adhesion tests.
For insights regarding the outcomes of adhesion tests, installers can reach out to NanoTech Materials’ Technical Sales Support Services

NanoTech Recommends the following test method:

Field Peel Adhesion

Overview: The ASTM D903 “Peel Adhesion” test is a standard procedure in roof coating guidelines, particularly effective for onsite testing with elastomeric materials. This test, along with a similar one, ASTM D3359 “Tape Adhesion,” is applicable for evaluating primers and enamels.

Preparation:

Create a sample section of the intended coating system on the current roof surface. Execute any required mechanical surface

preparations.

Replicate cleaning processes via power washing.
Coat 6” by 2” of the substrate with a single layer of the NanoTech Materials Cool Roof Coat.
Set up at least three (3) test patches for the initial 100 squares and an additional patch for each subsequent 100 squares in various

areas of the roof to test adhesion for any doubtful roof substrates. Test Method:

Insert approximately 6” (152 mm) of a precut 1” (25 mm) x 12” (305 mm) fabric strip into the wet coating. Keep an extra 6” (152 mm)

of the fabric strip free for pulling during the test.

Add another coating layer to cover the moistened section of the fabric.
Allow sufficient drying time, which can range from 8 hours to 48 hours depending on the weather. Ensure the test patch is not

exposed to rain during the cure time. Evaluation:

Employ a force gauge, such as a digital fish scale or a trigger pressure gauge.
Utilize a loop, staple, or clamp to secure the fabric to the gauge.
Gently pull the fabric straight upwards at a 90-degree angle; the average force should exceed 2 PLI (Pounds per linear inch of

fabric width).

2.0 General Installation

THESE ARE GENERAL INSTALLATION INSTRUCTIONS. REFER TO THE ROOF

SUBSTRATE SPECIFICATION FOR MORE DETAILS ON INSTALLATION

Technical Advice

The application of this coating should be executed with guidance from the manufacturer’s technical representative. For assistance,

contact NanoTech Materials Technical Services.

Repairs

Address all leaks and seal flashings on the existing substrate using comparable materials as suggested by the original manufacturer

prior to the application of NanoTech Materials Roof Coatings. Areas repaired recently may necessitate an appropriate primer. For primer suggestions, consult the NanoTech Materials ancillary systems list.

Seams, Penetrations and Detail Work

Use NanoTech Materials Roof Sealant, applying it via brush or roller with a minimum width of 6 in (152 mm) over the seam at a rate

of at least ½ gallon per 100 sqft. Immediately place a 4 in (102 mm) strip of Reinforcing Polyester Mesh Tape into the wet coating, ensuring full integration into the coating. The Reinforcing Polyester Mesh Tape should be laid out smoothly, devoid of wrinkles, “fish mouths,” blisters, or pinholes. *As an alternative to conventional 3-course, it is recommended to apply NanoTech Materials TriSeam at a rate of 2 gallons per 100 linear feet.

Once the initial coating with the embedded fabric is firm to touch, add another layer of NanoTech Materials Roof Coating at a

minimum of ½ gallon per 100 sqft for thorough encapsulation of the tape. Allow a drying time of at least 4 – 6 hours (in conditions of 75ºF (24°C) and 50% RH) before progressing to the subsequent installation step. Be aware that lower temperatures or higher humidity can prolong drying times. Do not apply NanoTech Materials Roof Coating if rain or heavy dew is anticipated within 8 hours. Aim to apply the product in the morning for optimal drying time during daylight. The product should be walkable in 90 minutes.

Roof Equipment (HVAC / Sleepers)

Units resting on 4 in x 4 in (101.6 mm x 101.6 mm) wooden sleepers should be raised to allow for cleaning, priming (as necessary per

adhesion test results), and coating of the membrane beneath them as per the guidelines in this document. A protective slip sheet should be placed under the sleepers to safeguard the coating system. If units are not elevated from the deck to facilitate this process, the unaddressed area will be exempt from warranty coverage.

Primer

Should adhesion tests indicate a need for primer, apply NanoTech Materials Primer in accordance with instructions, avoiding any

pooling on the surface. The required Minimum coverage rate is 300 sqft per 1 gallon. The primer can be applied using one of the following methods: brush, roller, or sprayer. Be mindful to prevent puddling when spraying. Allow the approved Primer to dry completely. Drying times can vary and are dependent on ambient conditions.

Product Circulation Guidelines

This is a high-solids, acrylic emulsion formulation that is a non-Newtonian fluid. This means that the product must be thoroughly

agitated to lower its viscosity from a solid state to a liquid state. If the product is left standing in the packaging, or in the application machine, or any container after agitation for more than 45 minutes, it must be agitated again to prevent its viscosity from increasing back to a solid state from a liquid state.

Follow these simple guidelines:
Agitate the product using a helicoidal paddle and a mixer with high rpm capability for at least 10 minutes when applying from a

5-gallon bucket.

Agitate the product for at least 5 minutes and up to 10 minutes for a product that has been left standing in a bucket for more than

45 minutes. If product is shipped in a drum or tote the product should be agitated utilizing an EvenMix dual paddle tote mixer for a minimum of 45 minutes.

The life of the product after being opened and resealed is 30 days or less, depending on how well the leftover product has been

sealed in a container that does not allow air circulation. Inspect and remove any cured resin or solid bits from a used bucket, if any, before using leftover product and follow agitation guidelines.

Acrylic Coating Base Coat

Apply NanoTech Materials Cool Roof Coating at an average rate of 2.5 gal/100 ft² to achieve a Wet Film Thickness (WFT) of 28 mils.

The application should not exceed 2.5 gal/100 ft² per coat. NanoTech Materials Roof Coating can be applied with a 3/8 in (10 mm) nap roller, brush, or airless sprayer. Ensure all surfaces are coated, including expansion joint covers and flashings. Apply an extra coat around all edges and penetrations. Adjust drying times as necessary for environmental conditions (see note below).

Second Coat

Repeat the application of NanoTech Materials Cool Roof Coating at the same rate to achieve the specified WFT of 56 and DFT 40.

Follow the same application techniques as the base coat. Allow sufficient drying time, adjusting for environmental factors. *NOTE- When a 20-year NDL with 2” hail is required, an additional 1.5 gallons per 100 sqft of NanoTech Materials Base Coat (24 WFT / 15 DFT) is required. Base coat is to be applied as the primary coat. NOTE: MINIMUM DRY TIME PER COAT IS 8 HOURS AT 75ºF (24°C) AND 50% RH.Expect longer drying times in cooler temperatures or higher humidity. Avoid applying NanoTech Materials Cool Roof Coat if rain or heavy dew is expected within 8 hours. The product should be walkable in 90 minutes.

NOTE ON AIRLESS:

Use a 2,000 – 3,000 psi (13.8 MPa – 20.7 MPa) at the gun tip, with a flow rate of 1.6 –3.0 gal/min (3.8 L – 11.4 L/min) and tip sizes

ranging from 0.025 – 0.040 in (0.64 – 1 mm). Larger spray units are beneficial for longer hoses on bigger projects. For assistance in selecting the best equipment for specific project needs, contact Technical Services.

Any deviations from the specified standards identified by the Applicator or the owner’s representative must be rectified by the Applicator.

Preparations shall include, but shall not be limited to, the following: PLEASE NOTE: During coating application procedures, NanoTech Materials Cool Roof Coat shall be applied a minimum of three (3) inches above the termination of all flashings, repairs, and bridges. That is, coating shall be applied to sections of parapet walls, the bases of air handling equipment, penetrations, and the like. Section 7.0 of this specification should be consulted for details. These surfaces must be adequately prepared in order to ensure adhesion of the NanoTech Materials Cool Roof Coat membrane. Metallic Surfaces: 1. All metal flashings, expansion joints, penetrations, and other metallic surfaces that are to be coated shall be prepared according to the following procedure. 2. As much loose rust and scale as possible shall already have been removed by abrasion (wire brush or other suitable instrument) from oxidized areas. Primer application shall not commence during inclement weather, when a precipitation appears imminent, when the temperature is below 45°F, or when the relative humidity exceeds 85%. To provide adequate curing time, primer application shall terminate a minimum of two (2) hours before sundown. 4. Entire surface to be primed with NanoTech Materials Rust Inhibiting Primer rust conversion primer for metal shall be free of dust, dirt, tar, oil, moisture, frost, or any other material that would impair the adhesion of the primer to the substrate surface. 5. Using conventional airless spray equipment, brush, or roller, all galvanized, phosphated, and non-painted metallic surfaces that are to be coated—metal flashings, expansion joints, air handling equipment, penetrations, and the like—shall be primed with NanoTech Materials Rust Inhibiting Primer rust conversion primer for metal, or equal, at a rate of 100 to 200 square feet per gallon.

All surfaces to be primed with cutback asphalt or asphalt primer shall be free of dust, dirt, debris, degraded asphalt, moisture, or any other material that would impair the adhesion of the cutback asphalt or asphalt primer to the substrate surface. 1.3. Using conventional airless spray equipment, brushes, mops, or other suitable equipment, the entire aluminized asphalt surface shall be primed with cutback asphalt or asphalt primer at an approximate rate of 300 to 400 square feet per gallon. 1.4. Primer shall be allowed to cure for at least 24 hours. Primer must be dry before coating application commences. 2. In order to minimize color bleed-through into the top coat, the following procedure should be followed (bleed-through will only affect the appearance, and not the integrity, the performance, nor any other physical property of the NanoTech Materials Cool Roof Coating membrane): 2 .1. If the entire surface to be coated has been primed, all surface preparation procedures (sections 4.0-6.0) shall be completed before starting this procedure. However, if only part of the entire surface to be coated has been primed, it may be desirable to complete this procedure before completing the rest of the surface preparations to allow additional time for curing. 2.2. Using conventional airless spray equipment or rollers, apply a base coat of NanoTech Materials Cool Roof Coat to the surfaces primed with cutback asphalt at an approximate application rate of 1.5 gallon per 100 square feet. NanoTech Materials recommends that a darker color, like gray, be used for this procedure, since this accelerates the curing process. 2.3. It is possible that bleed-through will occur in this base coat, producing discoloration (“coffee stains”). Allowing the base coat sufficient extra curing time tends to lock the bleed into the base coat, preventing the bleed-through from continuing into the topcoats. 2.4. The base coat should be allowed to cure for at least ten (10) days, longer, if possible, before a subsequent coat is applied.

NanoTech Materials Cool Roof Coat

Revolutionary Acrylic Coating

Description

NanoTech Materials Cool Roof Coat is a high-performance, elastic polymeric coating used in the protection of roofs, walls, and buildings. The product acts in the direct protection of the surface and in the reduction of the heat absorbed from structures exposed to sunlight, due to its reflectance, emissivity, and low constant of thermal conductivity properties. Due to its efficiency, this product reduces the degradation caused by the incidence of UV radiation and allows the maintenance of flexibility, resistance, and longevity of existing roofing materials. As heat transfer is reduced, this product helps reduce energy consumption in buildings and also reduce the amount of carbon-based gases in the atmosphere from cooling systems.

Application

This product is primarily designed for outdoor use. For the application of this product, you must wear protective clothing, gloves, and glasses. For a high-quality application, a minimum ambient temperature of 40°F and rising with a maximum relative humidity of 85% must be respected. Never apply the product at temperatures below 40°F, as the product is water-based, and freezing will cause irreversible damage. This product should not be exposed to rain, water, or any other liquids during application and for 48 hours after the final layer has been applied. See application manual for more details. Before starting the application, repair the entire coverage of the roof with suitable products. When possible, the product should be applied on a clear and/or sunny day. Application can be carried out using a 3/4” external paint roller or professional airless sprayer. For a detailed application process, consult our application manual. For quality and performance gains, the material should be applied in thin layers of at most 28 wet mils (typically one coat of an airless sprayer). Apply the second coat perpendicular to the first and so on. The consumption of the product will be 2.5 gallons per 100 square feet. On our 10-year warranty system coating should be applied 28 wet mils and dry film thickness (DFT) should be a minimum of 20 mils. For further details on our other warranty systems, please view our Cool Roof Coat Coverage Rates. Allow a minimum of 4 hours between coats. A complete cure requires takes 24 to 48 hours.

12.3 Care & Preventative Maintenance

Overview

A roof, constantly exposed to various weather elements like heat, cold, UV rays, and physical damage, is often one of the most vulnerable parts of a building’s exterior. However, its long-term performance can be significantly enhanced through proper design, quality materials, correct installation, skilled workmanship, and a thorough maintenance program. The investment in a comprehensive maintenance plan is considerably less than the costs associated with repairing or replacing a damaged roofing system. As a crucial component of the building envelope, the roofing system requires careful attention. Early identification and resolution of potential issues are key to preventing minor problems from escalating. Regular maintenance not only maintains the roof’s integrity but also protects the building’s contents and minimizes disruptions to its use. Consistent and detailed maintenance schedules can prolong the life of the roofing system and reduce overall life cycle and replacement costs.

Understanding the Importance of Proper Roof Maintenance and Repair

All roofing systems, including those that are coated, necessitate routine maintenance and repair. The Roof Coatings Manufacturers Association (RCMA) suggests inspecting roofs and coatings twice yearly, typically in spring and fall, as well as after significant weather events. Additional coating should be applied as needed to repair damage to the coating or the underlying roofing substrate. Application of extra coating is also advisable where the existing coating is worn thin. NanoTech Materials requires the application of a 20 mil (DFT) topcoat at the ten year inspection mark, in order to recertify the roof for another ten years.

General Care and Maintenance Recommendations

For optimal performance of the roofing system, consider the following general care and maintenance tips:

Ensure proper drainage to reduce standing water on the roof. Keep the roof surface clear of leaves, pine needles, twigs, paper,

dirt, and other debris that might clog drains. Trim back trees or branches that are too close to the roof. Standing water on the roof increases the likelihood of moisture infiltration in case of punctures or other mechanical damage to the roofing membrane.

Regularly inspect the building’s exterior for signs of settlement or movement. Cracks in walls could indicate potential issues with

the roof substrate and flashing. Check the condition of overhangs, cornices, fascia, and edging.

Protect the roofing system from substances that could cause early degradation of the coating or membrane, such as:
Petroleum-based liquids
Solvents
Grease from rooftop units or restaurant vents
Oils (new or old) from air conditioning or compressor units
Kitchen waste or animal fats
Chemicals – Contact Technical Support Services for information on chemicals incompatible with the coating
Use catch pans or other protective measures to shield the roofing membrane from exposure to grease, chemicals, and other

substances. Spills should be promptly cleaned to prevent swelling and possible degradation of the roofing system.

Look for signs of algae, mold, mildew, or other plant growth on the roof, especially in shaded areas prone to water retention.
If snow removal is necessary, use plastic shovels and exercise caution around protrusions or detailed work areas. Avoid using snow

blowers, picks, axes, and sharp-edged shovels on the roof.

Remove any foreign debris like glass, bolts, nails, screws, metal shavings, and other materials that could puncture or cut the liquid-

applied coating or roofing system.

Limit access to the roof. Most roof damage occurs due to unauthorized or uninformed individuals. Access should be restricted to

authorized personnel only, and visitors and maintenance personnel should be informed about necessary precautions. Maintain a log of all visitors and maintenance personnel accessing the roof.

Instruct maintenance personnel to avoid dropping tools and equipment on the coated roof surface to prevent puncturing the

membrane. When working on rooftop HVAC units, antennas, solar panels, satellite dishes, etc., take care not to place tools, metal doors, lids, pans, or sharp objects directly on the coating system surface. Use smooth plywood to protect the coating membrane when moving roof-mounted units or equipment.

The Building Owner is responsible for repairing any physical damage to the roofing system, either through the original contractor or

another certified contractor. Delayed repairs to physical damage can lead to the need for major repairs or replacement of the roof or roof coating system at the Building Owner’s expense.

Annual Inspections

During annual inspections, be aware that the liquid-applied coating can become slippery in wet conditions. Caution is advised when

walking on this type of roofing system or coating during or following rainfall, or in the presence of moisture such as dew, frost, or ice. Special attention is needed on lighter colored surfaces where ice or frost may not be as noticeable compared to darker surfaces.

These involve cleaning and a thorough visual check of the roof coating system. Inspections should assess the overall condition of

the coating, as well as the integrity of elements like flashings, vent pipes, protrusions, skylights, drains, gutters, parapet walls and caps, adjoining walls, and mechanical equipment. Additionally, look for signs of biological growth or any other foreign debris.

NanoTech Materials, Inc. | NanoTechMaterials.com | (888) 296-6266

Preventative Maintenance Program

This program includes regular inspections and subsequent corrective measures, designed to extend the life of the roofing system.

It’s advisable to schedule these preventative maintenance inspections in spring and autumn. Preventative maintenance programs are recommended by the manufacturer but are included in the service contract and the responsibility of the installing contractor to coordinate with the end customer.

Additional Inspections

Beyond regular annual inspections, additional checks should be planned if the roof encounters unusual physical damage or

conditions, including but not limited to:

Exposure to extreme weather, such as strong winds, hail, or prolonged heavy rain.
Extensive water pooling, debris accumulation, and any damage to building components that might lead to moisture penetration

of the roofing membrane. In areas affected by severe conditions, check the coating or liquid-applied system for punctures, tears, abrasions, or detachment.

Following repair or replacement of rooftop equipment or during other activities by different trades that could potentially damage

the roof.

It is important to check for spills, debris, sharp objects, punctures, excessive wear, or other damage caused by heavy traffic or

alterations to the roof.

Cleaning Procedures

WARNING: Be cautious of the slippery nature of the liquid-applied coating when wet, especially during cleaning.

Clear the roof of rocks, branches, leaves, pine needles, and other foreign materials, as well as dirt build-up near drains and other

low points. Utilize tools like a plastic rake or a medium-bristle brush for debris removal, applying minimal pressure. Clear any blockages from drains, gutters, and downspouts, ensuring downspouts on multi-level roofs do not discharge directly onto the coated surface below. Trim overhanging trees to reduce leaf and pine needle accumulation and allow sunlight to reach the roof, aiding in the prevention of mildew and algae growth.

Generously apply diluted Cleaning Concentrate (1 part concentrate to 10 parts water) at low pressure to a section of the roof, using

about 0.4 to 0.7 gallons per 100 ft² (1.6 to 2.9 L/m²). Let the cleaner sit for at least 15 minutes. Ensure areas with algae, mold, or mildew are thoroughly soaked. These spots should also be scrubbed with a medium to stiff bristle brush for optimal removal.

Rinse using a pressure washer (1,200 to 1,500 psi) with clean water directed towards drains. Employ a fan tip on the wand,

maintaining a minimum distance of 12 inches (305 mm) from the roof surface. Additional scrubbing with a broom or cleaning pad may be required in dirtier low areas. IMPORTANT: Use roof wash-off catchment systems where necessary and comply with local and state regulations during the cleaning process.

Pre-Inspection

Before conducting the roof inspection, it’s essential to prepare a detailed roof plan to document any defects and observations.
Inspect the underside of the deck (if accessible) and the exterior of the building before accessing the roof. Look for indications

of excessive moisture, staining, or deterioration. These signs can provide insights into not just roof-related issues but also other factors impacting the overall performance of the building envelope.

Area of Concern	Treatment
Parapet Walls & Caps	Inspect the interface between the roof deck and parapet walls to verify

there are no splits or tears and that the coating membrane is properly adhered and intact. Check parapet walls and caps for cracks or breaks that might allow moisture intrusion beneath the coating system.

Minor Repairs Areas requiring minor repairs (such as small punctures and tears)

identified during the inspection can be fixed with NanoTech Materials Rain Safe Leak Repair or NanoTech Materials Roof Sealant.

Roof Drains & Scuppers Confirm that roof drains and scuppers are unobstructed and free from

debris for effective drainage. Ensure drain covers are secure and properly fastened. Check the surrounding coating for integrity and absence of blisters, tears, and delamination.

Protrusions Scrutinize the reinforced coating around all protrusions, like vent

pipes, for splits, tears, or delamination at the base. Confirm proper cap installation on vent pipes and the secure, self-flashing condition of the coating at the top of all protrusions. Moisture Analysis (optional) If there’s concern about moisture penetration into the roof substrate due to damage, consider conducting a non-destructive moisture detection survey. Common methods include nuclear metering and infrared thermography. A moisture meter probe can also be used, though this is destructive and will require repair of the damage.

Skylights Examine the reinforcement around skylights, ensuring it is intact and free

of blisters, tears, and delamination.

Gutters Maintain clean gutters, clear of debris to promote proper drainage. If

drains are coated, inspect the coating for soundness and absence of blisters, tears, and delamination. Roof Membrane & Flashings Examine the roof coating membrane to ensure it is intact and undamaged, checking for splits, crazing, and cracking. In areas with standing water, inspect for blisters, delamination, or damage due to biological growth on the coating surface. Roof Mounted Equipment Inspect all rooftop equipment to ensure secure attachment to base risers, and that the surrounding coating and reinforcement is sound, free of blisters, tears, and delaminations.

Other Details Check the condition of bricks and mortar on chimneys, as well as caulking or

joints in metal flashings, including copings, counter-flashings, rooftop units, curbs, caps, expansion joints, etc. Repair or replace caulking as needed.

Roof Specific Leak Investigation

On metal decks, it’s crucial to identify the orientation of deck flutes and deck slope. Water may seep through the roofing system, travel within the lower flutes of the deck, and cause leaks inside the building, particularly in lower areas. For concrete decks or projects where existing roofing material remains, leaks might stem from moisture trapped in the original installation. In roofing assemblies with poor insulation, leaks can result from condensation. Therefore, pinpointing the exact location and frequency of the leak is vital. Efforts should be made to seal any sources of air leakage. 1. Initiate leak investigations with a comprehensive visual inspection of the roof area corresponding to where leaks have been reported inside. 2. Examine key details such as drains, vents, scuppers, HVAC and other roof-mounted equipment, parapets, areas of ponding water, etc. In dry conditions, locations of water pooling can often be identified by residues on the roof membrane. Investigate lower roof areas for moisture beneath the coating system (soft insulation can sometimes be felt when walking over these areas). 4. Inspect mechanical rooftop equipment, drains, skylights, roof hatches, expansion joints, pipes, vents, etc., for any cuts or punctures in the coating membrane. 5. Check metal flashings (edging, coping, expansion joint covers, parapet caps, etc.) for cracks and poorly sealed joints. If the source of the leak isn’t visually apparent, wet the system in the suspected leak area and monitor the interior for leaks. 7. An inspection of the deck underside often reveals signs of water leakage and/or air infiltration.

Emergency Repairs

NanoTech Materials must be informed of any leaks within 30 days from their discovery. The Building Owner may undertake temporary repairs in an emergency to minimize damage to the building or contents. Such repairs should be executed by qualified personnel and won’t affect any existing guarantees or warranties, provided they are reasonable, customary, and do not permanently damage the NanoTech roofing materials. Permanent repairs should be completed by an approved NanoTech contractor, under NanoTech’s guidance for covered leaks, or as directed by the building owner for non-covered leaks. Repairs shall be achieved using NanoTech Materials Rain Safe Leak Repair. Before and after digital photography shall be conducted in order to maintain the warranty.
