How Does Moss Grow on a House in the Mt. Hood National Forest?

Moss is a type of plant that grows in damp and shady areas. The Mt. Hood National Forest provides an ideal environment for moss to thrive, with its cool and damp weather. Moss can grow on almost any surface, including roofs, siding, decks, and concrete.

Why is Moss Growth a Problem for Your Roof?

Moss and algae growth can cause several problems for your roof, including:

  • Uplifting shingles
  • Trapping moisture against your roof
  • Staining your roof
  • Forming a slippery surface that can be dangerous to walk on
  • Promoting the growth of bacteria and mold

How to Prevent Moss Growth on a House in the Mt. Hood National Forest

To prevent moss growth on your roof, here are some tips and tricks:

1. Trim trees and branches

North-facing and shaded roofs are the most susceptible to moss growth. Trim any trees and overhanging branches that are casting excessive shade to help prevent future moss and algae growth that causes unsightly black stains on your roof. Sun exposure is your friend.

2. Install zinc strips

Zinc strips are effective in preventing moss growth on roofs. For best results, install zinc strips at the top of the roof just below the ridge or first row of shingles. Rainfall will wash the zinc down your entire roof, creating a protective coating that will prevent future moss and algae growth.

It’s important to note that zinc strips are not meant to clean your roof and you should clean your roof prior to installing the zinc strips.

3. Regular roof maintenance

Regular roof maintenance is the best way to prevent moss growth. Keep your roof free of debris, trim trees and branches, and regularly clean your roof to keep it in good condition. It is important to keep your gutters clean as well.

How to Remove Moss from a House in the Mt. Hood National Forest

If moss has already started to grow on your house, don’t worry. There are several ways to remove moss from a house in the Mt. Hood National Forest. Here are some steps you can take:

Scrub the moss away

You can remove moss from your roof and siding by scrubbing it away with a stiff-bristled brush. A power washer may be a tempting choice, but pressurized water can blow granules off your shingles and damage your roof. If you do choose to go that way, put your power washer on a very low setting and spray down the slope of the roof. Spraying up may lift or break shingles and cause water intrusion into your attic.

Use a moss removal solution:

There are many moss removal solutions available that can be applied to your roof and siding to remove moss growth. In the Pacific Northwest almost every home improvement store will have several options. The best time to apply is late fall and early spring, right before the peak rain season.

Can moss grow on metal roofs?

Yes, moss can grow on metal roofs if the conditions are right, such as high humidity and shade. The collection of organic matter on the roof is a big factor so remember to keep the roof clean. However, metal roofs are less susceptible to moss growth than other roofing materials. If the time comes to replace your roof, look into metal.
