Roof Cement Q&A

What is Roof Cement Used For?

Roofing cement can be used for a lot of different types of repairs. Usually it is used to fix a leaking roof, whether it be a shingled roof or something other like metal or rolled roofing.

Most roof cement is either tar or silicone based. The tar based ones are the best for long term repairs, but are harder to apply in wet weather. Whereas the silicone based products can be used in wet or dry weather.

Another benefit of either application is that both types of sealants can be used to also repair things like flashing leaks, gutter repair and even if you have the tar based application, fixing your driveway.

How to Apply Roofing Cement?

There are two types of sealant, and each type has it’s own application methods.

For a tar or asphalt based cement like the Gardner-Gibson brand I reviewed above, you’ll need either a trowel for larger areas, or a putty knife for smaller areas. You can of course use anything flat to apply the cement, even a piece of shingle. Just be sure to wear gloves and keep the tar off your skin.

For the silicone based ones you usually need to use them with a calking gun. Some brands to have their own applicators included, but usually a calking gun is required.

Does Roof Cement Harden?

Yes, over time roof cement will harden. But that may take ten to twenty years for some products.

In order to keep it’s water proof structure, most roof cements are created not to harden. But over the years of weather and sun, almost any compound will harden. Check the warranty as this will be a guide as to how long your product should fight hardening.
