You have probably seen a mass of moss on your roof, especially if you live in humid areas. Moss growth on your residential roof and under the shingles reduces curb appeal. But, besides the appearance, moss significantly affects your roof's operation and longevity. This article explores the impact and prevention measures of residential roof moss growth.
Effects of Roof Moss
Moss may seem harmless, but untreated growth spreads and causes the following damages to your residential roof.
Moss is naturally wet, and constant humidity on your roof causes decomposition and rot. The rot reduces your residential roof's structural integrity. Also, rotten sections are more susceptible to holes, breaks, and leaks.
Reduced Roof Life Span
Mosses are porous and hold a large amount of water. So, after rains, moss becomes heavy and exerts a lot of weight on your residential roof. The situation forces your residential roof to accommodate the unnecessary extra weight and weaken. If left untreated, the strain from the moss reduces your roof's life span.
Moss growth on your residential roof tends to lift the shingles. When the shingles are out of place, water seeps beneath your roof and causes decay to the wood frame. Deteriorated shingles are also weaker to the elements and can be pried off with ease when heavy rain and strong winds blow.
Roof Moss Remedy
Most growth is preventable regardless of your climate or roofing system. Read on to discover the steps to prevent residential roof moss.
Trim Your Trees
Overhanging trees block sunlight from your residential roof and trap moisture from heavy downpours. The shade and humidity are the perfect environments for moss growth. So, prune branches that extend near or above your residential roof to reduce humidity and allow more sunlight.
Debris and other organic matter on your shingles, gutters, and residential roof offer a good base for moss growth. For instance, the debris traps water that facilitates the spread of the moss. So, make the environment unconducive for moss with roof and gutter clean up.
Opt for Moss Resistance Roofing Components
If you get frequent damage on your shingles from moss, opt for copper-infused asphalt shingles. Copper-infused shingles, or a combination of zinc and copper, prevent moss growth. You could also nail zinc strips along the peak of your roof. Then, after a downpour, the zinc gets released to your roof to hinder moss growth.
If you already have growth on your roof, remove the moss first, then take the necessary preventive measures to avoid regrowth. Unprofessional moss removal can cause further damage to your residential roof. So, work with an experienced residential roofing professional who won't harm your roof further.
