Frequently Asked Questions
Simply put, to save you money. Instead of spending 10 times as much to replace a roof that still has years of life left, proper cleaning will safely restore your roof back to its original beauty and effectiveness.
Our cleaners are completely safe for your roof. In fact, they are recommended by the Asphalt Roofing Manufacturers Association. Our cleaning method is also safe for your roof; we never use a pressure washer on your roof.
Be careful choosing a roof cleaning contractor; often a particularly low price is indicative of a poor-quality job. In this case, it can mean severe damage to your roof.
Roofs are most commonly replaced because of their appearance. If your roof has black stains, dirt, leaves, or lichens, we can clean it with our unique non-pressure system method.
For many years, roof discoloration caused by algae has been observed throughout the United States and Canada. The discoloration usually has a brown to black appearance and may be mistaken for soot, dirt, moss or tree droppings.
The primary species of algae being observed is called Gloeocapsa Magma. This type of algae is contained in and transported through the air, and tends to collect and grow upon roofing structures.
Natural pigments produced by these algae may cause a white or light colored roof to gradually turn brown or black.
Algae discoloration should not be confused with moss or tree droppings, which typically produces only localized discoloration. Besides looking bad, this algae also feeds on the limestone filler in your shingles. It is literally eating away at your roof.
Call Sully’s Green Clean now; we have a proprietary method of killing the algae, washing, and treating your stained and infested home or business using a completely safe and proven soft wash chemical cleaning system.
This is a safe, non-pressure chemical wash that will last 4 to 6 times longer than pressure washing.
This process has been used for nearly 20 years and has been proven safe and effective for cleaning all types of roofs, siding, home exteriors, soffits, gutters, driveways, sidewalks, fences, decks, patios, screen enclosures, pool decks and pavers.
If your roof shingles are still under their warranty period and still in good shape, call us to have them cleaned. If there are any leaks due to minor shingle damage or a few missing shingles, call us anyway and we can make simple repairs first! Opting to clean translates into you paying a fraction of the cost of installing a new roof!
Cleaning your roof is not just a cosmetic repair. The black streaks will prevent your shingles from deflecting the sun properly and can increase your cooling costs.
Also, since the algae is feeding on the limestone in your shingles, it is slowly breaking them down. By not cleaning your roof, you are reducing the life of your shingles by up to 50%!
