How Often Should I Pressure Wash My Roof?

December 20, 2018

It’s easy to see when it’s time for your home’s exterior is due for its annual pressure washing, but homeowners often forget about their roof. While your roof may not need as much attention as the rest of your home, it’s important to remember rain does not wash your shingles. In fact, rain and wind lead to a build-up of debris on the roof, which leads to the growth of algae and moss.

Here’s How Often You Should Pressure Wash Your Roof in Melbourne, FL

On average, a pressure wash is recommended nation-wide every two or three years. Florida homes may need it more frequently, especially after a heavy storm. You also want to make sure you are always compliant with your HOA rules. If you notice dark patches on your roof, it’s a sign mold is growing.

Depending on your roofing materials you may need to take extra care when pressure washing. An asphalt composite shingle roof requires a soft pressure wash that does not harm the granules in the shingles. Tile roofs also require a soft wash.

Asphalt Roofs

Pressure washing on an asphalt composite shingle roof requires no more than about 30 psi. This is similar to a garden sprayer but you need special equipment to safely reach the entire roof. Professionals should pressure wash an asphalt roof. A professional pressure wash includes a special non-toxic cleaner that does not harm the shingles or metal fastenings.

Tile Roofs

Tile roofs are popular throughout Central Florida. It’s important to take special care not to crack tiles while pressure washing. Clay and ceramic tile roofs require the same low setting as asphalt tile materials. You can also seal clay tiles with a protective coating that discourages the growth of moss and other organisms.

Rain Gutters

Rain gutters are part of the roof system and need to be washed when they are full of dirt, leaves, and other debris. A careful power washing cleans most gutters and the downspout.

This prevents the growth of mold under the roof eaves and on the walls of the building. A thorough roof pressure washing should be done by a professional company.
