So you have a 3 tab roof that you want to last 5 more years before replacing? So, what we can do for you is remove the moss in the safest way possible whether that is with a brush or with low pressure washing, followed by gutter cleaning, treatment, sealing exposed top nails, recaulking the flashing, chimney etc. Whatever needs to be done. Lets get that roof cleaned and sealed for protection so that you may get some more years out of it before buying a new roof. Any repairs necessary we can help you with and will always take before and after photos and let you know what it needs before we do any work. Happy holidays everyone!
