When You Need Roof Algae Removal
Most homeowners and property managers call us for roof algae removal after seeing one of these: black or green vertical stains on north-facing slopes, uneven roof appearance from the street, or neighbors getting their roofs cleaned. Each one is a real signal that something has shifted and needs hands on it.
The usual causes in the DMV are Gloeocapsa magma algae thrives on shaded DMV roofs and feeds on the limestone in modern shingles. Heavy summer thunderstorms, freeze-thaw cycles, and the tree canopy across Montgomery and Prince George's Counties speed up every one of those failures. Wait a season and you almost always end up paying twice — once for the original fix, and again for the water damage it caused.
Our Roof Algae Removal Process
When you call, we set a same-day or next-day visit. On site, our process is straightforward. First, we apply roof-safe algicide and let it dwell. Next, we soft-wash the surface and rinse clean. Finally, we install zinc or copper strips at the ridge to prevent regrowth. You get a written estimate before any work starts, and photos of anything we find that you cannot see from the ground.
Most algae cleanings are completed same day with a 2 to 5 year prevention warranty. You get a copy of the work performed and any warranty paperwork the same day.
