Tips For Applying Elastomeric Roof Coatings To Your Home

Posted on

If you have decided to apply an elastomeric roof coating to your home to reduce your energy bills and help keep your home cooler in the summer months, then you will be happy to learn that there are some simple things that you can do to ensure that you get the best coverage possible.

Follow these tips when applying an elastomeric roof coating to your home.

Clean the Roof and Fix Cracks Prior to Installation

To achieve a smooth surface of elastomeric coating on your roof, you should first sweep the roof with a stiff push broom to remove any dirt, twigs, and leaves that have collected on the roof's surface. Follow the sweeping with a power washer to deep clean the roof. You need to let the roof dry completely before applying the coating or it will bubble when it gets hot.

After washing the roof, patch any cracks using a silicone roofing caulk compound. By using an inexpensive caulking gun, it will be much easier and faster to apply the caulking over using a tube that you squeeze like toothpaste.

Only Apply Elastomeric Roof Coatings on a Hot Sunny Day

Elastomeric roof coatings are designed to be installed over a dry roof, on a hot day. The heat helps the coating to cure and dry. In addition, the heat helps the coating to adhere to your existing roof's surface. If you try to install an elastomeric coating on a cold day or on a wet roof, the coating will not have a flat surface and it will fail when the weather changes.

Apply Elastomeric Roof Coatings with a Large-Napped Roller or Airless Sprayer

Elastomeric roof coatings have a similar texture to a thick oil-based paint. Since you are applying this thick substance to the rough surface of your home's roof, you will need to use a large-napped roller to achieve the proper level of coverage. If you use a roller with a nap that is too small, then you will not get a thick enough coat of the roof coating on the roof. This will lead to an uneven appearance of the coating and possible leaks later down the line.

Finally, if you have an airless paint sprayer that can handle the thick coating, then it is a good option for this application. Use wide strokes to apply the paint and make sure you clean your sprayer well when you are finished. For assistance, talk to a professional like Stetson Painting.
