It’s not uncommon to see black streaks or green moss growing on the roofs of homes in Maine’s communities.
While the appearance may lend itself to what some may consider a desirable contrast to the roof color, most often, it means there’s moisture present that can erode the roofing material and shorten the lifespan of your roof.
Moss typically starts growing on the shaded areas of the roof, especially under overhanging tree branches or any place that lends itself to a cool, moist environment. The moss that you see on the surface of your roof also means that there are most likely roots underneath that have attached themselves to your shingles and roofing material beneath the surface.
Moss, and sometimes algae, will spread on roof surfaces quickly. When you see the discoloration, resist the urge to climb a ladder to remove it. Instead, call a professional to provide a roof inspection to ensure there’s no moisture penetrating under the shingles leading to roof damage.
Here are some suggestions of what to do—and not do—if you have moss or algae on your roof.
Don’t Power Wash It Yourself
It may seem like an easy fix to just power wash off the discoloration. However, this isn’t recommended as a DIY solution. The wrong pressure, chemicals, or process will quickly damage the roof shingles, wearing them down rapidly. Call Horch Roofing today to have it done right.
Do Call a Roofing Professional for an Inspection
An inspection of your roof performed by a professional will allow areas of concern to be examined to ensure that no underlying structural moisture problems exist. Tackling these issues right away helps prevent long-term complications.
Do Invest in Roof Maintenance
You can often control some of this growth with good roof maintenance. For example, keep tree branches off the roof and keep the gutters clean to minimize the amount of material present to allow moss buildup. Our team at Horch Roofing can provide gutter cleaning for you. It’s also best to have a yearly roof maintenance check just to ensure your roof is debris-free.
Don’t Put Off Repairs
If your roof needs repairs, getting them done sooner rather than later is always the best course of action. When the damage is significant, and other precautionary measures to avoid moss growth can’t be taken such as removing trees or increasing sunlight to the area, consider replacing your existing roof with a metal roof that won’t allow for this type of growth.
Install Copper or Zinc Strips Near the Peak or Use Algae-Resistant Shingles
Installing copper or zinc strips under the row of shingles closest to the roof peak can prevent moss buildup. Molecules of the metal will wash down the roof when it rains, and because the molecules are toxic to moss and algae, the growth of both is prohibited.
Another reliable option to prevent moss from occurring is to use asphalt shingles that have metal particles embedded in the granule surface.
