Those nasty black streaks on your roof are not just an eye sore, they could be damaging your shingles.

I founded Windows Only in 1998 in my hometown of Bethesda, Maryland. After working for several years for other window cleaning companies, I found myself dissatisfied with the way those businesses sacrificed quality and safety to make a buck. I decided to try going into business for myself. With those early experiences in mind, I have built Windows Only around the principles of professionalism, safety, superior workmanship and outstanding customer service. Starting as a small, one-man operation focusing only on window cleaning, I have grown Windows Only into a successful business that today offers many services to Montgomery County.

Those nasty black streaks on your roof are not just an eye sore, they could be damaging your shingles. Windows Only provides safe, effective roof cleaning without the hassle. Let us take care of your roof today. Contact us today to schedule a FREE no obligation estimate or repeat visit. What are the black streaks on my roof? The black streaks are actually an algae called Gloeocapsa Magma. The algae feeds on the minerals present in most roofing shingles, which may cause slow deterioration of the shingles.
