Roof treatment Lake Oswego
There’s an adage about roofs: they will treat you as well as you treat them. For NW Homes Exteriors, that includes providing seasonal roof treatment services in Lake Oswego to protect against all the elements we experience in the Pacific Northwest. Depending on the type of roof you have, a roof treatment in Lake Oswego from NW Homes Exteriors involves using safe, environmentally friendly products to prevent moss, mildew, and other types of fungal or bacterial growth from making a home on your roof.

Typically, our roof treatment services take place after we’ve cleaned your roof and/or gutters. However, plenty of Portland Area homeowners call on us for roof treatment services at different times of year, no matter when their last roof cleaning was. One of the biggest reasons is because a proper roof treatment demonstrates great results, especially during the rainy season. You can see your roof treatment services working when you look up and notice how clean your roof looks compared to other roofs around your neighborhood (unless they’re working with NW Homes Exteriors too).

Protect Your Roof and Your Home.
Your roof takes a pounding, especially in a place like Lake Oswego. Rain falls nine or ten months out of the year. There are periods of fog, ice, and intense winds that come out of the Gorge, or sometimes from Coastal storms. In the winter, we can deal with snowpack’s that can last weeks. Then comes more rain, followed by gorgeous summers where temperatures can vary, from the low 80s, all the way through triple digits for days at a time.
What does it all mean for your roof? Well, over the course of the year, it can be the perfect breeding ground where things like moss, fungi, mildew, algae, and lichen grow at will. When they do, they turn your shingles into their home, and begin wearing away at the material you need to keep you covered through every season. As such, finding roof moss treatment in Lake Oswego becomes a requirement. NW Homes Exteriors treat and manage the factors that affect your roof’s condition. Instead of roof treatment services in Lake Oswego being a chore you keep putting off, we’ll come out and do it on an annual, quarterly, or semi-regular basis, however many times a year you need.
