Brentwood is the hardest zip code in Middle Tennessee to keep clean, and it is entirely down to the trees. Mature canopy over most of these lots means the north and east walls barely see direct sun from October to April. Shade plus humidity is exactly the environment algae wants, which is why houses here green up faster than the same house would three miles east.

Every part of Middle Tennessee dirties up differently. Here is what actually shows up on the trucks in Brentwood.
The wall you are unhappy with is almost certainly the one facing north, or the one behind the big oak. Those surfaces stay damp for days after rain. Nothing about the siding is wrong. It is a growth problem, and a wash that kills the organism rather than knocking it off is the only thing that buys you real time.
Brentwood roofs are large, and those black streaks running down from the ridge are gloeocapsa magma, a living algae feeding on the limestone filler in your shingles. Left alone it shortens shingle life. We treat it at low pressure per ARMA guidelines. Anyone who puts a pressure washer on your roof is voiding the shingle warranty and stripping granules.
The driveways out here run long, often 800 to 1,400 square feet with a turnaround, and they are usually bordered by planting beds somebody paid real money for. Plants get soaked before we start, sensitive material gets tarped, and everything gets rinsed again at the end. Tell us about a koi pond or a vegetable bed and we work around it.
Roof work starts at $549 and runs $0.30 to $0.45 per roof square foot. Brentwood roofs are big, so most land between $650 and $1,100. Roofs steeper than 8/12 add 20 percent because they need different safety equipment and take longer. We tell you that up front rather than discovering it on the day.
We do not price by zip code. What you see here is what a Brentwood homeowner pays, confirmed in writing before we start.

Tree cover. Shaded siding stays damp long enough for algae to establish, and most Brentwood lots have mature canopy. It is not a defect in your siding or paint. Homes on heavily shaded lots here usually want an annual wash where a house in full sun could stretch to two years.
No, and they are not stains, they are living algae. A proper soft wash treatment kills the organism and the streaking clears over the following weeks. After the first treatment most roofs go two to three years before needing it again.
House soft washing runs $299 to $699 depending on square footage, concrete is $0.22 per square foot, and roof soft washing starts at $549. Given the size of most homes here, a house plus concrete job typically comes to $600 to $1,000, and adding the roof puts most properties in the Full Exterior or Property Reset package range where you save 15 to 18 percent.
We pull your property on satellite, measure the roof and concrete, and text you a firm number the same day. No sales visit.
