Your previously pristine roof now looks green and fuzzy. Instead of shingles gracing the exterior of your home's top, your roof suddenly seems like a garden filled with greenery. And while you adore the garden you have growing on the ground, you never expected to see plant life above your head.
Why does your roof look like it's covered in a shag carpet? It's likely that you have a moss infestation. Even though some structures have purposeful green roofs, your home isn't one of them. The moss that's sitting on your shingles isn't helping your roof.
A mossy roof may look rustically chic, but in reality the green growth is a problem that you need to deal with immediately. What do you need to know about roof moss growth? Take a look at some of the top questions that homeowners have about this roofing invader.
Why Remove the Moss?
The quaint look of moss may make it seem innocent. But the growth on your roof could cause problems that you don't even know about. Moss grows in moist conditions. As it sits - and grows - on your roof, it acts as a sponge. It thrives on the moisture, pulling it in.
The water that the moss holds against your roof can cause mold growth that extends into your home. A constantly damp roof that leaks into the attic can also result in rotting wood and serious structural damage. Failure to remove the moss means that the moisture stays put. The resulting problems can cost you money in repairs, reroofing, or damage contractor fees.
Removing the moss is the only way to stop the water issues that it's causing. Remediating mold may temporarily help. But if you still have a mossy layer on your roof, the moisture is likely to cause regrowth. The same goes for rotting wood and other water-related damage.
What Does the Moss Removal Process Include?
To start with, a DIY approach to moss removal isn't advisable. A damp roof is slippery, especially when it's covered with a layer of moss. Climbing onto the roof to remove the mold is dangerous if you don't have the right expertise or equipment. Leave the moss removal up to the pros. They know how to fix the problem and repair any underlying issues, such as replacing broken shingles or damaged subroofing materials.
A roofing contractor can evaluate your roof's individual needs and create a plan of removal. This may include physical removal of the plant life as well as chemical treatments.
Along with the slippery safety issue, some moss removers rely on harsh chemicals. These are also best left to the experts. Misuse of chemical moss cleaning agents can result in a health hazard or further damage to your roof.
What Prevents Moss From Growing?
In a perfect world you could control the moisture that reaches your roof. But that won't happen. There's no way to make the rain go away permanently, and that means you have to deal with the possibility of moss growth and regrowth.
How can you prevent a re-infestation after you get through the removal process if you can't stop moisture from building up on your roof? Metals such as zinc and copper can stop moss growth and prevent it from coming back later on.
A professional roofing contractor can install metal strips (zinc or copper) on your roof. As rainwater washes over them, the metals will rinse down your roof and stop moss growth from reappearing or taking over. This is a non-chemical solution to your roof infestation issues.
