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 Durham 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 Durham to clear algae, moss, and lichen with low pressure and the proper solution, protecting both the shingles and the manufacturer's warranty.
Shade over the older Durham neighborhoods keeps roofs damp longer, and black streaking establishes early on the north slopes. It soft washes off; nothing here should ever see pressure.
Durham has the oldest housing stock in our area. The neighborhoods around Duke and downtown are painted wood, original brick, and mature oak canopy, which means shaded walls green up early and gutters fill with more than pine straw. Almost none of it wants pressure. We soft wash the siding and hand-clear the gutters.
Durham commercial splits three ways. Research Triangle Park office and lab buildings judged on entrance glass and walkways. Downtown and the tobacco district, where restored brick and restaurant patios sit right on the sidewalk. And the medical corridor around Duke, which holds a standard of its own.
Neighborhoods we cover: Trinity Park, Old West Durham, Hope Valley, Woodcroft, Southpoint, Duke Forest, Watts-Hillandale, Downtown and the American Tobacco district.
Durham has the oldest housing stock in our service area, and the exteriors reflect it. Painted wood around Trinity Park and Old West Durham is frequently on its third or fourth coat, and anything above low pressure will find the weak layer. Heavy canopy across the older neighborhoods keeps walls damp late into the morning, so algae establishes earlier in the season than it does further east. Gutters here fill with hardwood leaf mat rather than pine straw, which composts in the trough and holds water against the fascia.
Durham work runs from soft washing century-old painted wood near Duke to routine vinyl washing in Woodcroft and Southpoint. Commercially we clean entrances and walkways across Research Triangle Park, restored brick and patio concrete in the tobacco district, and the patient-facing approaches around the medical corridor. Older properties frequently need a conversation about what will and will not lift before we quote.
Durham's canopy pushes the calendar earlier than the open subdivisions east of here. Shaded north walls near Duke and downtown show growth by March, well before pollen season ends, and waiting until May means living with it for two extra months. We generally treat the shaded elevations early and come back for a full house wash after the pollen drops. Gutters here fill with leaf litter as well as pine straw, so a fall clearing after the oaks finish matters more than it does elsewhere in the Triangle.

“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! The dirty white vinyl and aluminum is now beautiful again! The outside stairwell going into our basement in particular was a nightmare and now it looks like new! Their pricing is also very fair.
