Intra-lock Roofing System
The I.R.S. consists of three products:
Seal Kote, SPF Poly Fab Membrane, and Kool-Kote Elastomeric White Roof Coating.
When properly applied, the finished system will yield a tough film between 55 and 65 mm thick.
The system conforms to any shape and adheres to any sound surface. This is ideal for new roof construction, repair, or restorations. It seals and bridges minor cracks and surface defects, as well as resists ponding water on flat roofs with poor drainage.
Poly Fab fabric is recommended for all roofing surfaces, new or old, whenever seams, flashings, vents, or other equipment such as refrigeration units or skylights are present.
This permits a high film build over areas of excessive movement caused by severe temperature changes, and old weathered substrates.

Seal Kote
Seal Kote is an elastomeric waterproofing roofing material used as the base/prime coat on all types of roofing surfaces. Our product is absolutely pivotal when fixing up your old roof keeping your new roof pristine. Seal Kote's rubber-like film encapsulates and seals surfaces to prevent leaks, and produces a tough durable finish that forms a barrier against weather and chemical deterioration. Seal Kote's elastic, self-flashing film conforms to any shape and can be used with fabrics to reinforce patches, flashings, vents or any other roofing protrusions. When this film is cured, it can elongate to over 300% of its original length without cracking, and withstands the most severe weather conditions, remaining pliable even at -20°F
and keeping you worry free!

SPF100 Polyester
Ply-Reinforcement
SPF100 stitch bonded polyester is one of the strongest materials available to the roofing industry for use as reinforcement in cold process roofing. SPF100 is very soft, providing excellent conformability and elongation for irregular surfaces, such as filled gravel, asphalt shingles and corrugated metal.
Kool Kote Roof
Coating
Our Kool Kote roof coatings are specially formulated Acrylic Elastomeric Latex Sealants that are designed to reflect the extreme heat from the sun and extend roof life. It is made to adhere to any roof surface, while sealing and water proofing joints, cracks, penetrations, flashings, and scupper drains. Kool Kote will remain flexible and strong at temperatures as hot as 180°F and as cold as 15°F.
Kool Kote is your #1 hero for keeping you comfortable

Apply a reinforcing support that will help prevent cracking or any physical damage that might reduce the lifespan of your roof's protection.
Finish with the final layer that is specially designed to keep you kool! This will provide maximum protection for your roof against the sun while simultaneously lowering the temperature inside your home.
