Atlanta Roofing-How do I control moss and what damage can it cause to my roof?
Atlanta roofing contractors are very familiar with how moss, molds and mildew are enemies waiting to attack your roof. Once moss forms it acts like glue, sticking debris and dirt to the shingles or tiles. That causes moisture to accumulate, which can lead to decomposition, rot and cracking. Pretty soon, new mildew and algae begins to feed on the moss, leaving dark, ugly stains and emptying your wallet.
So, how can you control moss from growing on your roof here in the Atlanta area.
Atlanta roofing contractors have some tricks of the trade to share with you.
The first and foremost preventative action you can take is to keep tree branches at least ten feet away from your roof. Branches can drop gooey sap and small twigs as well as dead leaves. If you trim back the branches, debris will not build up as much. Air flow in and around the roof will improve. Just like algae can form in stagnant water, moss can form where there is little air flow.
When you trim back the branches of trees shading your house it also minimizes the shade on your roof. Sunlight deters the growth of moss. True, people think that a shady roof will lower their utility bills, and it may very well do that.
An Atlanta roofing contractor can tell you, replacing a roof is a far more expensive undertaking.
If it is your neighbor’s tree that is encroaching onto your roof, please handle with care. You do have the right to protect your property, but remember you have to live next door to them. Perhaps you can spit the cost of a good arborist who will prune the limbs correctly and prevent further growth in your roof’s direction.
Remember to not let debris such as twigs, dirt and leaves build up into the crevices and corners of your roof, especially along the gutters and chimney. That is an open invitation for moss to settle in. You do not want moisture to accumulate. Dry roofs are less moss-prone.
Be aware that if the neighbor up the street has a mossy roof, their airborne spores can head in your direction and lodge onto your roof. Moss control is a neighborhood affair as well. There is a deterrent that can be sprayed over a dry, clean roof. However, this should be applied by a professional Atlanta roofing contractor. If you notice other homes in your area of Atlanta have signs of moss growth on their eaves and roofs, get yours treated as soon as possible.
Atlanta roofing contractors commonly use Zinc sulfate which can last up to four years.
For the most part, a clean, sunny roof is a moss-free roof. Do what you can to fight this battle all year long. Just because it is summertime and the spring rains are over, or winter and all the leaves have fallen doesn’t mean the mold spore count in this area cannot be high. Keep an ear out for allergy forecasts or call your local news station to see if their weather trackers have any information on high mold counts.
