Here in the Southern Willamette Valley, we are located in the Marine West Coast climate zone, where over half of our annual precipitation falls between November and February. However, Spring and Fall are also moist seasons, with light rain falling for long periods.  Our wet and cool environment promotes the growth of moss, algae, and lichen. While it can look beautiful out in nature, it can actually be very damaging when it grows on your roof!  Moss and mildew can drastically reduce the service life of asphalt shingles, tile, shake, and other roofing materials.

Fortunately for you, the experts at Arrowhead Roofs have years of experience cleaning, treating, repairing and protecting roofs all over Eugene, Springfield, and the surrounding Southern Willamette Valley and Central Oregon Coast.

Extend The Life Of Your Roof

The average lifespan for a residential roof in the Southern Willamette Valley is 15 – 18 years. But with regular moss removal, chemical treatment and general maintenance- you can extend the life of your roof by ten years or more! We use a very safe and effective method that will assure your roof is healthy and looks great!

How We Clean Moss From Your Roof

We begin by agitating any large clumps of moss with a stiff brush. Then we blow all the loose debris off the roof with a commercial grade backpack blower. We clear all the debris from the inside of the gutters and check that all the downspouts are clear.

Prevent Moss Regrowth With Chemical Treatment

We then apply granular zinc sulfate to the roof to kill any remaining moss. Zinc sulfate is cost effective and kills all moss within one month. It is USDA approved and won’t harm your plants or siding. Rain and wind naturally wash away remaining dead moss. Note: We use a liquid moss treatment for cleaning roofs that are particularly steep or difficult to access.

Even newer roofs should be treated with zinc sulfate to ward off the growth of moss. But if we’ve already had to remove moss from your roof- consider having regular treatments to prevent the rapid regrowth.
