Cleaning your roof is important for a couple of reasons. First, don’t you want your roof to look nice? Getting regular roof cleanings can keep your roof looking as good as new or the day you bought your home. Second, regular roof cleanings help prevent pesky invaders such as mold and algae from growing and causing damage to the surface.

When providing regular maintenance to your roof, you should have it cleaned once a year. If your roof is newly installed, you don’t need to clean it as frequently. If you have had a brand new roof installed, it’s recommended that you get it cleaned no less than every 2 years.

The amount of time it takes to clean a roof depends on factors such as the size of your roof and what kind of condition it’s in. On average, it takes anywhere between 2 to 5 hours to clean a roof thoroughly. Times vary on a case-by-case basis, and a member of our team is happy to give you a more accurate estimate once they assess the situation.
