"Our roof had black streaks for years — we thought we needed a replacement. D&D did their soft-wash treatment and it looks brand new. Saved us thousands. Would recommend to anyone."

Address roof growth without treating it as a repair
Professional roof cleaning is the safe removal of moss, algae (Gloeocapsa magma), lichen, bird droppings, and black streaks from asphalt shingle roofs using a soft-wash method, low-pressure application (under 500 PSI) of a shingle-safe sodium hypochlorite and surfactant solution.
Moss and staining can change the appearance of a roof, but the cleaning approach must suit the roof covering. A roof-cleaning enquiry starts with the material and visible condition, rather than a promise to make an ageing roof new.
Material comes first
Asphalt shingles, metal and other coverings have different care requirements. GAF cautions against high-pressure washing on its asphalt shingles; cleaning choices should follow the relevant roofing manufacturer's guidance.
Growth, staining and damage are different
Surface growth can be a cleaning concern, while missing material, leaks and damaged flashing need a repair assessment. Removing visible buildup does not establish the roof's remaining life.
A useful view from the ground
Accessible photographs can show the affected slopes and nearby planting without anyone climbing up to prepare an enquiry. Height, roof shape and the material help define a suitable cleaning proposal.

Customer stories
What our customers say
Review row 1
★★★★★
"Three other companies quoted us pressure-washing. D&D was the only one who explained why that's a bad idea and showed me the ARMA bulletin. That's the company I want doing my roof."
★★★★★
"Moss on the north side of the roof was out of control. They killed it, lifted it, and rinsed everything — including our flower beds. Professional from start to finish."
★★★★★
"The drone assessment made it really easy to see exactly what they were going to do. Before-and-after photos are night and day. Already booked them for gutters too."
