Our roof repair system keeps your commercial building leak free for 20 years. Keeps water out of your building twice as long as any new single-ply roof, costs less and pays you back with air conditioning savings. Applied over any type of existing roof, even if there’s two or more layers. Deducted immediately as a repair expense. When we do asphalt roof repair, flat roof repair or metal roof repair, your roof becomes a brilliant white seamless waterproof membrane. Perfect for rubber roofs and spray foam insulation too. We’ve specialized at custom roof coating applications on the west coast since 1986. We have an excellent reputation and hundreds of references!
