The black streaks on your gutters are in the oxidation layer of the paint. They can be removed with the correct chemicals.

You’re correct! A roof should not be pressure washed as it will void the warranty on your roof and damage the shingles. At Keystone Pressure Washing and Roof Cleaning we use a Non-Pressure Roof Cleaning soft wash method with no pressure applied. So. Instead of using high water pressure and force-heavy cleaning, we use safe pressures and specially blended cleaning solutions to remove all of the grime and dirt from your building exterior. It’s an effective cleaning method for exteriors of all materials, and we use it frequently on vinyl, wood, stone, brick, and stucco.

We clean: Asphalt shingles, slate, barrel tile, and EPDM Flat roofing surfaces.

No, all of our chemicals are eco-friendly. We also take special care to pre-wet all plants and landscaping and rinse when we are completed.

No your roof does not need to be replaced. Most of these stains are called by algae (gleocapsamagma) which is airborne and can land on any roof surface. It feeds on the limestone fillers in the shingles and when it rains the algae is spread down the roof surface. This causes the streaking/staining. Not only can we clean the streaks and staining, but we can prevent it from coming back. Shingle manufacturers recommend that you clean your shingles on a regular basis. For more information read Don't Replace It, Clean It!, a technical bulletin published by the Roof Cleaning Institute of America and Algae Discoloration of Roofs, document was prepared by the Asphalt Roofing Manufacturers Association.

Depending on the size of the roof, our crew is typically completed within the same day.

No you do not. We ask that all doors and windows are closed, and for the outside water source to be on. We also ask that all outdoor furniture is moved away from the surface to be cleaned.

We offer weekend and evening appointments to accommodate your busy schedule.

Yes it can be cleaned. Wood can turn gray when it is weathered. It can be brought back to its natural beauty with our services.

Yes they should. The algae and mildew can make these surfaces slippery and hazardous. These elements can also be tracked into your home creating an unhealthy environment.

Siding manufacturers recommend cleaning every 12-24 months. Every home is on a case by case basis, however, depending on the elements surrounding the home.

No it will not. We use a low pressure cleaning method which is no different than a rainfall in combination with the right chemicals.
