Those black streaks on the roof are an algae called Gloeocapsa magma, and pressure washing a roof to remove them voids warranties and tears up shingles. In Chapel Hill we soft wash instead: a low-pressure treatment that kills the algae and moss and lets the rain rinse it clean.
A clean roof lasts longer. Central Triangle Pressure Washing soft washes roofs across Chapel Hill to clear algae, moss, and lichen with low pressure and the proper solution, protecting both the shingles and the manufacturer's warranty.
Shaded Chapel Hill roofs streak sooner and heavier than anywhere else in our area. North slopes frequently need attention while the rest of the roof still looks acceptable.
Chapel Hill is the most tree-shaded town we serve, and it shows on north-facing walls. Heavy canopy means less direct sun, slower drying, and algae that establishes earlier in the year than it does a few miles east. Roofs here also collect more organic debris, so gutters and roof washing come up more often than elsewhere.
The commercial side is campus-adjacent retail, restaurants along Franklin Street, and professional offices. Patio and sidewalk concrete near food service needs more frequent attention than a typical office park.
Neighborhoods we cover: Franklin Street, Meadowmont, Southern Village, Glen Lennox, Estes Hills, Coker Hills and the neighborhoods off Fordham Boulevard.
Chapel Hill is the most heavily shaded town we serve, and every exterior problem here is a moisture problem first. North-facing walls dry slowly, roof slopes hold organic debris, and decking stays damp enough to grow algae that makes boards genuinely slick. Growth establishes weeks earlier in the season than it does in open subdivisions a few miles east, and it returns faster after cleaning unless the treatment kills it rather than rinsing it off.
Residential work here is soft washing shaded siding, clearing roof streaking on north slopes, and treating decking that has gone slick rather than merely dirty. Commercially we handle Franklin Street storefront glass and patio concrete, campus-adjacent retail, and professional offices off Fordham Boulevard. Restaurant patios in the center need a schedule rather than an annual visit.
Chapel Hill runs on a longer growth season than anywhere else we work because the canopy holds moisture through most of the year. Roof and north-wall treatment can be needed twice annually here where once is enough in Holly Springs. Deck and walkway cleaning is best scheduled in late spring or early fall, when there is a dry stretch long enough for a treatment to set. Gutters need two visits: one after the spring pollen and one once the hardwoods have finished dropping.

“Central Triangle Pressure Washing did a great job washing our house! They were on time and worked hard to make our brick and vinyl house look better than ever!
