SPF OVER METAL ROOFS
WEATHERIZING AND INSULATION SYSTEM
Weatherproofing – Roof-Tek SPF over metal has the longevity that an owner requires, these system have 30 years of proven performance. The seamless spray foam insulation has no joints or fasteners to ever leak. And offering additional protection is the liquid applied membrane, which can be silicone, acrylic or urethane. All Roof- Tek coatings are elastomeric and are suitable for various climates. Silicones have been used extensively and offer superior resistance to UV. Our coating systems are sustainable, and in the future they can be simply and easily recoated, with low cost and no wasted materials. The materials are fully bonded and adhered to the metal substrate, so they offer excellent resistance to wind damage. And they perform without the thousands of penetrating fasteners other recover systems require. If rust has started on the roofs; these systems will seal the metal from the conditions that cause rust.
Movement – Movement can tear apart a metal roof, stressing seams, fatiguing fasteners and causing seals and flashings to fail, the superior insulating properties of the SPF will control this movement. By insulating metal roofs from the top side, expansion and contraction are reduced; also the panels are strengthened by the full adhesion of the rigid, higher-density, spray foam insulation. All fasteners and flashings are resealed with the seamless SPF.
