Kill the Moss...Keep the Roof
There's a slogan you may see on the back of one of our shirts in the summer as we service roofs in the Willamette Valley: "Kill the Moss...Keep the Roof." We're geeky enough to think it's catchy, but more importantly, we think it's true. Unless you have a metal roof, moss is an almost unavoidable roof problem in the Pacific Northwest. First the bad news: moss can contribute to the early decomposition of your roof, it can serve as a safe harbor for mold, and it's just plain unsightly. Your insurance company may even object to it when it's time for your homeowners insurance to renew. Field underwriters have been known to delay or decline a renewal when moss is flourishing on a home's roof. Here's the good news: it's very manageable and relatively affordable to deal with. Many homeowners have experienced the sense of relief that comes with the realization that their roof may have years of life left once the moss is cleaned away. The anticipated expense of an immediate roof replacement can evaporate with a little knowledge and some old-fashioned elbow grease. If you're considering hiring a professional to get your roof moss under control, here are a few helpful suggestions:
1. Make sure the pro you hire is experienced and trained in roof moss removal. It's
a different scenario than moss on your lawn or driveway - you have a roof to protect.
2. Get some references. If the pro has the experience, it's reasonable to expect that he/she
also has satisfied customers.
3. Find out what method of removal is used. Pressure-washing an asphalt shingle roof could
impact the validity of your roof's manufacturer's warranty. Better to have it done by hand.
4. Get a fixed quote. Moss is quantifiable. If this was a construction or repair project maybe
a more flexible estimate could be expected, but it's not - it's a cleaning service.
5. Make sure the pro you choose is insured. Don't be uncomfortable asking to see their
certificate - it's a request a commercial property manager won't skip.
6. Find out what method/treatment is used for preventive maintenance. Moss is like a weed,
it will keep trying to come back.
Ultimately, this extra due diligence can really pay off. When you find the right pro, don't forget, treating the moss annually is very affordable and can keep it from re-establishing. Your home's "hat" helps keeps you safe and the house sound, so "kill the moss...keep the roof."
