Maintaining your roof in the rainy NW can feel relentless.

At NW Home Exteriors, we know you want to protect your most valuable asset and avoid costly roof replacement. In order to do that, you need to stay on top of your roof maintenance in Lake Oswego each season and each year. The problem is, the NW climate is really brutal on our homes. The constant rain and weather are the perfect breeding ground for moss growth, built up debris, and eventually leaks without proper roof maintenance services.

You may be fearful the damage has already been done, or that you won't remember exactly when and what to do each year to stay on top of it. We believe everyone deserves a roof that lasts without the headache of annual maintenance.

We understand how busy life gets, which is why we've spent the last 16 years helping customers like you extend the lifespan of their roof by setting up a proactive Lake Oswego roof maintenance services plan that takes care of cleaning and moss treatment on auto-pilot. You never have to worry about it again!

We believe everyone deserves a roof that lasts.

Most moss removal chemicals cause more harm than good.

Roofing companies tend to focus on getting the job quickly but not necessarily with the long game in mind. They use chemical moss treatments made with sticky oils that damage shingles and nails while attracting debris and bugs. Not only do they cause damage, they don't last.


We take an eco-friendly approach to roof moss treatment using state approved products that won't harm your pets or plants! We guarantee you'll be moss free for at least 3 years!
