What does roof sealant do?
To increase its life expectancy roof sealants are applied to your roof. The sealing of a roof provides an additional layer of protective insulation that can help to prevent damage from extreme temperatures and other conditions outside. Sealants are particularly useful for types of roofs that accumulate water and debris such as flat roofs.
What to apply roof sealant with?
To seal the joints between the flashing and the chimney or any other surfaces, use special masonry caulk together with roof sealant. Seal the seam between the cap and flash stage with cement urethane roofing or silicone caulking compound.
How long does roof sealant take to dry?
In general it takes 8-24 hours for the roof coatings to dry completely. The difference in the time period depends really on the weather conditions. Dew and high humidity allow the coating to cure for longer. Hot dry weather temperatures will cause the coating to dry at much faster speeds.
How much roof sealant do I need?
One gallon covers 80 square feet of corrugated steel roof and a smooth metal roof of 100 square feet. You need one gallon for every 50 square feet of roof surface if you have a synthetic or changed bitumen, cement, built-up, or bonded tar-and-gravel roof.
