Through the Roof! by Sashco got its name because it can seal anything that goes through the roof, including vents, skylights, chimneys, flashing, pipes, gutters and downspouts. It also can be used to glue down individual shingles that have been lifted by the wind and can fix shingles damaged from hail. On the interior, the sealant can prevent heat leaks from the attic side of the home, reducing heating bills and preventing ice dams.
Developed as an offshoot of the company’s Lexel product line, which was introduced in the 1970s, Through the Roof! is a customer-driven development after Sashco realized people were using Lexel for roofing applications. Through the Roof!’s formula has extra antioxidants and SPF protection to give it more durability and make it more suitable for shingles and other thin-coating applications.
The substrate is clear and does not leave a yellow, cloudy residue, ensuring it blends with roofs. It also does not stick out like black asphalt-based sealants. Unlike silicone-based products, this solvent-based product sticks to building materials, including asphalt shingles, tile, glass, brick, rubber membranes and existing roof patches. The elastomeric compound stretches without tearing, cracking or pulling away, and expands and contracts with weather conditions.
One of its distinctive attributes is that it is immediately waterproof and will stick to wet surfaces. Through the Roof! can be applied during a storm to immediately stop leaks and can be applied in temperatures between 0 and 120 F, making it suitable for year-round use.
Through the Roof! is available in 10.5-ounce traditional caulking cartridges and quart and gallon container brush-on grades. Using a foam, coarse utility or paint brush, it can be brushed on from 1/16- to 1/8-inch thick. The caulking cartridge can cover approximately 30 lineal feet with a 1/4-inch bead. A quart container will cover about 3 square feet at 1/8-inch thick. The sealant can be painted over with latex paint/stain after 24 hours and with oil-based paint/stain after one week.
