Sashco Inc. has released Through the Roof!, a clear roof-repair caulk made to permanently stop and prevent roof leaks. It seals around a variety of rooftop fixtures and roofing materials without the messy look of asphalt. The product expands and contracts with temperature changes. It can be applied to wet surfaces and exposed to rain and snow immediately. It also won't turn brittle in the sun or cold. Through the Roof! is available in cartridges and brush-grade quarts and gallons.
