Once the moss is removed, the best line of defense is regular moss treatments. We can add moss treatment to any other service provided, or simply do it as a stand-alone service. We often are asked when the best time for treatment is. Timing is everything. You want to apply a moss treatment after the heavy rains have subsided so the treatment is not immensely rinsed off. However, you want to be sure there is still enough moisture to dissolve the treatment and let it wash down your shingle, not blow off in the dry wind. This is when calling us to be sure you get the most out of your treatment is helpful.
