What we do
- Roof Cleaning and Soft Wash Those black streaks are algae, not dirt. The shingle manufacturers call it a surface stain rather than structural damage, so this is about how your house looks. We remove it with a low-pressure soft wash rather than a pressure washer, which is the method they actually approve. Roof Cleaning and Soft Wash
- House and Driveway Power Washing Siding, decks, patios, walkways and driveways. We match the pressure to the surface, so vinyl gets a gentle wash and concrete gets what concrete needs. House and Driveway Power Washing
- Gutter Cleaning and Installation Clearing, repairs, new gutters and guards. Fall cleaning matters more here than most places, because clogged gutters are how ice dams start. Gutter Cleaning and Installation
- Exterior and Interior Painting Prep, repair and paint, inside and out. Outside we usually follow a wash so the surface is actually clean first, and inside we prep the walls, trim and ceilings properly before anything goes on. Exterior and Interior Painting
- Roof Repair and Replacement We hold a Massachusetts Construction Supervisor License, so we can do the structural work most exterior cleaning companies have to refer out. Roof Repair and Replacement
- Siding Repair and Replacement Vinyl siding repair and full replacement. We strip the failed siding off, deal with what we find underneath, and install new siding that closes the wall back up. Siding Repair and Replacement
Why the black streaks come back
If you have dark vertical streaks running down the north or shaded side of your roof, that is a blue-green algae called Gloeocapsa magma. It spreads by airborne spores and settles where the roof dries slowest. The shingle manufacturers call the staining a surface problem rather than structural damage, so this is mostly about how the house looks. Under heavy tree cover, which describes most of Belmont, Weston and Lexington, it comes back faster because the roof stays damp longer after rain. Pressure washing it off will strip granules and shorten the life of the roof. A soft wash uses a cleaning solution and low pressure to kill the organism instead of blasting it, which is why it is the method the shingle manufacturers sign off on.
