Dallas Roofing: Article About Preventing and Eliminating Moss On Roofs
Moss is a natural occurrence on roofs in humid climates and cool temperatures. Moss may be quaint on fairy tale cottages, but in real life, it's quite unsightly and destructive to all roofs regardless of their materials. Homeowners with a major moss problem should consult with their Dallas roofing company for an effective course of action.
Moss only needs three things to grow: shade, moisture and cool temperatures. It doesn't need a particular surface to grow on, so wood, clay, slate and metal roofs all provide equal opportunity for growth. It's damaging to roofs because it retains moisture, and moisture is a prime reason why roofs deteriorate more quickly than they should. Moisture opens the roof up to wood rot and structural damage, and it lowers the home's value if it's visible.
Removing the moss before it completely overtakes the roof is critical. There is a variety of ways to get rid of it, and inexperienced homeowners should work with their roofing professional before they try to handle a moss problem on their own. It's tempting to simply scrape or brush the moss off, but this doesn't effectively remove every bit of the moss.

Zinc sulfate is the most effective at eliminating all of the moss. It kills existing organisms and prevents the growth of future ones. As soon as it's applied to the roof, the moss will darken and dry up, making it easy to sweep off. It's not recommended homeowners apply this solution because it's quite caustic and damaging to exposed mucous membranes. One application can keep a home moss-free for up to seven years.
Zinc strips are another option. Moss cannot grow when exposed to zinc, and a constant application of the zinc particles will ward off any future moss growth. These strips won't kill existing moss, but it's an excellent preventative. These strips are applied in intervals on the roof, especially on peaks, dormers and eaves, so when it rains, the particles wash over the entire surface of the roof and inhibit moss growth. Unfortunately, very large roofs may require several hundred strips, which could be expensive. To avoid damage to the existing shingles or roof decking, these strips should only be applied by professionals.
Prevention is the best way to avoid roof damage from moss, but sometimes it's impossible to prevent it completely. If homeowners notice moss is starting to grow on their roof, they should consult with a roofing company immediately to mitigate the problem.
