Safe Roof Moss Removal

Posted on July 18, 2015

Moss removal should be a yearly maintenance strategy in the Pacific Northwest. For all of its charm, moss is a roof’s enemy. The longer it grows undisturbed, the more damage it does to the shingles. The moss slowly breaks up the roofing material. Eventually, it can eat all the way through. When that happens, you have only one choice—reroof or lose your most valuable asset.

Routine moss removal prevents moss from gaining a foothold. It’s also an opportunity to identify any issues—damaged shingles, loose gutters, missing end caps, etc.

Yet, safe moss removal goes beyond using the right chemicals or techniques. It includes safety. Falls from ladders and roofs lead to 150,000 urgent care visits a year.

That’s one of the main reasons Hayes Roofing encourages you to hire a professional. Sure you can do it yourself, yet is it worth the risks or the time involved?

How Long Does It Take to Remove Moss Safely?
Depending on the condition of your roof, it can take anywhere from one to two days to safely remove the moss from your roof. If there is any buildup, the job is tedious. It must be done correctly or your roof could be damaged and its life shortened.

For example, it’s very important to remove as few granules as possible from a composition roof. You also don’t want to damage or loosen cedar shakes.

Hayes Roofing Removes Moss Safely.
Helping you keep your roof as long as possible might seem counterintuitive for a roofing company, but that’s our goal. We focus on using methods that protect the integrity of your roof.

We also work with you to ensure that we’re using cleaning products and moss prevention chemicals that match with your eco-view. While zinc sulfate is a common regrowth preventative, it does have a downside. Any runoff that reaches streams and rivers can kill aquatic species.

There are other low-toxicity treatments, including baking soda, vinegar and ammonia, which will kill moss safely. For them to be the most effective, they must be applied correctly. That’s something Hayes Roofing has experience doing.

Of course, while we are on your roof, we’re going to do a thorough health check. That last wind storm may have damaged tiles. Your gutters may be clogged with leaves.

Prevent Moss to Begin With.
You can prevent moss to begin with. The next time you reroof your home, use algae resistant shingles. There are several alage or fungus resistant shingle systems available. We work with several products, and can recommend the best one to meet your needs.

The cost of the shingle is higher, but it costs the same to install. From there the savings continue to accumulate. Gone is the need for the yearly roof cleanings needed in the Pacific Northwest to remove moss and algae. Eliminated is the inevitable reduction in roof lifespan caused by careless cleaning methods.
