Roof Cleaning

Read This Before You Replace Your Roof

A properly performed, non-pressure Roof Cleaning could save you thousands of dollars! The average cost of a full roof replacement in the Susquehanna Valley is between $8-$13 thousand (that’s the cost of a car!). If you have these black streaks on your roof and have considered replacement, call us before you call a roofer. You could simply need a professional roof cleaning which will save you thousands compared to a full replacement!

Why Should I have Roof Cleaned?

Q: What are those black streaks on my roof?
A: The black streaks are a type of algae called ‘Gloeocapsa Magma’ or simply “Black Algae”.

Q: Is this type of algae harmful to my roof?
A: Yes it is. As this mold grows it feeds on the outer base of the shingle causing the shingle granules to dislodge reducing the life expectancy of the roof.

Q: I have 30 year architectural shingles on my home. Without treatment for roof fungus how long can I expect my roof last?

A: That’s a tough question to answer due to many factors, but in general a 30 year roof life expectancy can be shortened by up to 50% if left untreated. It is highly recommended that you contact a Roof Cleaning Professional if algae, moss, or lichen is visible on your roof (black streaks or staining).

Q: How do you clean my roof?
A: We use a process called “non-pressure roof cleaning” or “soft washing”. This is a process that eliminates the risk of damage to your roof often associated with old, high pressure methods. A specialized detergent, or “algaecide” is gently applied to the roof shingles and allowed to dwell, attacking and killing the algae which is feeding on your shingle and creating unsightly dark streaks and stains. As the algaecide is working, the algae will break up and die revealing a clean, “like new” roof!

Q: Can you really clean our roof without causing damage?
A: Yes, absolutely. Through the innovations in the pressure washing industry and the recommendations of ARMA (The Asphalt Roofing Manufacturers Association), there is now a recommended format for your roof cleaning. We follow your roof manufacturer’s recommendations and use the appropriate cleaning solution (algae resistant) along with a non-pressure application method to make your roof look like new. Additionally, this extends the life of your roof saving you from more costly repairs in the future.
