Frequently Asked Questions
Commercial roof cleaning will remove moss, algae, dirt, debris and other growth that can eat away at the roofing material and shorten the roof's lifespan.
Roof cleaning removes moss, mildew, algae and other growth that can eventually deteriorate the roof and cause leaks. Regular service can prevent moss and algae from growing. Roof cleaning is much more affordable than replacing a roof or repairing damage from leaks. We offer and recommend moss inhibitor application to slow the growth of moss and reduce the need for pressure washing roof surfaces. Of course we take every precaution to clean carefully preventing leakage in the cleaning process.
We can service nearly any roof! We clean asphalt shingles, slate and tile roof shingles, ceramic roofing tiles, metal roofing, flat roofs, 3-tab roof shingles, architectural roof shingles, wood roof shingles, shake roof shingles and more.
We utilize a professional water variable power washer and liquid detergent inject through machine to remove moss, algae, mildew, dirt, debris, grime, etc. Next, we apply zinc sulfate powder moss inhibitor to roof to slow the growth of moss going forward. We will also remove dirt, grime, leaves, debris, etc. from inside the gutter and utilize a hose as needed to remove grime from bottom and sides of inside of gutters. Next, we flush out the downspouts clearing them of any blockages ensuring proper drainage. Finally, we rinse any residue resulting from the roof and gutter cleaning off any siding and windows and remove and/or dispose of debris utilizing drainage filters where necessary.
We can clean delicate roofs with a commercial air compressor to remove moss, algae, mildew, dirt, debris, grime, etc. as possible from the roof.
Once the moss, algae, mildew, dirt, debris, grime, etc. has been removed and the zinc sulfate powder moss inhibitor has been applied, annual application of the the zinc sulfate powder moss inhibitor should prevent the need for additional roof cleaning. We still recommend an annual roof blow off to remove loose debris as needed. Of course, this varies based on the age of the roof, environmental factors and other conditions but we have found this to often be the case.
