Those black streaks are growth, and pressure is the wrong tool
The dark streaks running down a roof are mold, algae and moss feeding on the shingle surface, not loose dirt that blasting will fix. Asphalt shingles in particular can lose their protective granules when hit hard, so too much water pressure can cause damage to the shingles and shorten the life of the roof. On the shaded slopes around Beaver, Aliquippa and Ellwood City, the streaking tends to be at its worst.
That is why roof cleaning is soft washing. A low pressure application lifts the growth without scouring the surface underneath, and it is the right method for the roof you have, whatever it is made of. A roof that looks tired from the street often cleans up far better than owners expect, as long as the cleaning respects the material.
Asphalt, clay, slate and metal, each washed at low pressure
We clean all types of roofs: asphalt, clay, slate and metal. The material changes the details, since clay and slate are brittle underfoot and metal can be slick, but the principle holds across all of them: low pressure, the right cleaner, and a rinse that does not drive water where it does not belong. Shrubs and plantings below the roofline get covered first, and we work with environmentally friendly products.
Gutters ride along with the roof for a reason. Runoff from a cleaned roof carries loosened growth straight into them, and leaf-filled gutters left in place just give the next rain somewhere to overflow. Cleaning roof and gutters together makes sense, and the result is a roofline that looks right from the street and drains the way it was built to.
Why clear gutters cost less than the damage behind them
Regularly cleaning rain gutters comes down to a short list of payoffs. It prevents water damage, because overflowing gutters send water down siding and toward fascia and foundations. It protects the landscape, because a clogged gutter dumps its load on beds and shrubs in one spot. And it deters pests and rodents, which look for the wet debris a clogged gutter holds.
