Metal Roof Resoration for Fasteners & Seams


The major cause of metal roof leaks is the normal expansion and contraction of panels from temperature change. This movement causes fasteners to loosen and back out and seams start to leak.

Uni-Caps are a proven method for sealing fasteners on metal roofs. They are round disks consisting of an adhering butyl rubber seal.

Uni-Tape Seam Tape excels at sealing edges and seams on metal roof panels. It comes in 2-inch, 4-inch, and 6-inch wide polyester-reinforced, butyl rubber sealant tape.

After application, Butyl Caps and Butyl Seam Tape are top-coated with Elastomeric Roof Coating for longevity.

Spray Urethane Roof System

Big Mountain Insulators offers you re-roofing options for flat or low sloped roofs, mobile home roofs, and for metal roof restoration.
Our Spray Urethane Roof System re-roofs older structures with a seamless cover that not only improves the insulation value of the roof, it repairs leaks. Our system is sprayed on under pressure and cures immediately into a hard surface you can walk on without damaging it. To complete the system, a thick Elastomeric Coating is then applied to the surface to increase flexibility and protection. The surface is completely waterproof, seamless, good looking, and provides an R value of up to R-12 for an average two-inches applied. Warranties are available.

Spray Urethane Roof System adheres to just about everything so it can be installed over concrete, wood, steel, and most existing roof systems. It saves on the expense of roof removal and landfill fees.

"R" Value - has an "R" value of 6.5 per inch enabling it to provide more thermal resistance with less material than any other insulation. You will use less energy cooling and heating the building; therefore, reducing costs on your energy bill.

Seamless - forms a seamless insulated roofing system. Whether a roof is 10,000 sq. ft., 100,000 sq. ft or larger in size, it will have no seams.

Eliminates Flashing Leaks -is ideal for flashing parapet walls, roof penetrations and roof mounted equipment, including vents, pipes, stacks, HVAC equipment, skylights, and cooling towers.

Elimination of Ponding Water - In reroofing applications, ponding water may be eliminated by adding an increased thickness of polyurethane foam in low areas. Building up the low areas and sloping the roof so that it drains properly will eliminate ponding water.

Lightweight - weighs between 2-3 pounds per cubic foot. One inch of urethane foam insulation plus 30 mils of an elastomeric coating weighs approximately 60 pounds per 100 sq. ft., as compared to approximately 600 pounds per 100 sq. ft. for a typical conventional four-ply built-up roofing system.

Versatility - It can be used on both new and replacement roofs, whether flat, pitched, saw-toothed, domed or having unusual slopes or configurations. It is also ideal for the spray application to tanks, freezers, coolers, piping, ductwork and various aerospace projects.

Flexibility - It has the ability to withstand a structure's normal expansion and contraction without affecting the ability to keep the structure protected from the outside elements.
