Things to look at when you buy your roof sealant

Roof sealants vary in water resistance, UV reflectivity, longevity, and application. Learn more about these characteristics in our buyer's guide below to help you make an informed purchasing decision.

Water Resistance

Some sealants, like rubber, silicone, and polyurethane, have a waterproof quality and allow your covered roof to withstand significant rain, while other adhesives provide some level of water resistance. However, your sealant will require many applications to create a waterproof barrier. It'll give you instructions on how to accomplish it.

UV Reflectivity

Reflective sealant is a good idea for keeping your house cool in the summer. This is especially beneficial during the summer since it can lower air conditioning usage and result in a lower power bill. Silicone, neoprene, and polyurethane sealants have the most incredible reflectivity. The color of the sealant being applied will also influence its reflectivity; lighter hues are better at reflecting than darker colors.


Each sealant has a different lifespan, although the majority last 10 to 20 years. One layer of tape will keep tape sealants safe for a long time; however, the remaining liquid types may require many applications as a thicker coating stays longer. Another aspect to consider is the method in which the sealant is applied. If you don't follow the manufacturer's directions, you'll reduce the sealant's longevity. Most manufacturers advise against using their glue in cold weather, on a wet or dirty roof, or before a storm has had enough time to cure.

Different sealants require different techniques of application. The tape type of sealant has a straightforward application method, but the remaining sorts may be purchased in a paint can, spray can, or caulk tube. The color can technique gives you a thick coat of sealant and the amount required for a wide surface area. Spray paints and caulking guns require less effort, but they are only available in smaller amounts, making them ideal for small leaks.

How long does it take for a roof coating to dry after being applied fully?

The drying time of a liquid sealant depends on the sealant's formulation and the weather at the time of application, but most liquids will take between eight and 24 hours to dry.

What is the key difference between solvent-based and water-based roof sealants?

Solvent-based sealants are extremely weatherproof, but they're more expensive and require more work to apply due to their thick consistency and need for wearing a respirator.
