Roof Cleaning Services in Knoxville, TN
Our roof washing services in Knoxville, TN, remove algae, mold, mildew, lichen, and moss from your metal, tile, or asphalt roof. It involves an intense cleaning process with more than a cosmetic purpose. The black streaks on your roof are not just dirt, but rather a type of roof algae known as gloeocapsa magma.
Roof algae stains most commonly occur on asphalt shingle roofs because the bacteria can easily feed off the limestone contained in shingles. However, it also occurs on tile and metal roofs over time. If not maintained, roof algae can greatly reduce the life of your roof and should be removed promptly. Get a free estimate and 10% off when you call about our roof cleaning services in Knoxville, TN!
Moss Damage
Moss is an invasive plant, common in the greater Knoxville area, with roots that burrow underneath shingles and push them up exposing the interior to the elements. Our Knoxville roof washing services will kill moss but will not remove the leftover dead moss immediately, requiring several roof cleaning cycles before complete removal.
The dead moss will remain on the roof until it is eventually washed away after a multitude of wet and dry cycles. These roof cleaning cycles take 3-6 weeks on average before your roof will return to its original color after we’ve performed the roof cleaning service.
When you choose Brothers for roof cleaning in Knoxville, we will have one technician on the ground spraying a constant stream of water on all the plants and grass around the house to ensure there’s no damage to your landscaping. The other technician will spray the roof with our solution. We guarantees 100% satisfaction on all of our roof cleaning work. In rare cases, a second roof-washing treatment could be needed but will be covered by the original estimate.
Roof Washing in Knoxville
When should I have my roof cleaned?
You should get your roof cleaned every 1–2 years as part of regular maintenance to prevent the buildup of dirt, moss, algae, and debris, even if it appears clean. Schedule a cleaning if you notice visible growths like moss, algae, or lichen, as these can retain moisture and damage shingles. Cleaning is especially important after stormy seasons in Tennessee, or if your gutters frequently clog with debris from your roof. Additionally, cleaning before selling your home can enhance curb appeal and increase property value.
