Moss and algae tend to grow in damp, shaded areas and can cause damage to your roof both directly and indirectly. If you allow large patches moss to grow on your roof, these patches hold water against the surface of the roof, which can cause the roofing materials to rot and deteriorate. Therefore, having to replace your roofing more than needed. In addition, the water trapped in the moss pools in gaps between your roofs shingles, and as the water freezes and thaws it can pull the shingles apart, causing even more damage. The growth of moss on the shingles and the constant water underneath will also damage the shingles causing them to curl up on the ends. Over time if left untreated, the moisture will start to creep into the wood causing water damage and leaks in the roof. We suggest having moss removed on a regular basis so that way none of these situations happen to you! You can call us for a free estimate and our suggestions on a schedule to keep moss growth under control.
We have found the best way to remove moss from the roof is by using the back of a push-broom. We flip the broom on its back, the wood side, then walk from top to bottom in a straight line from the ridge to the gutter line. The moss gets knocked off and rolls down into the gutter where we can conveniently collect it before we treat the roof. Any excess that falls off we collect and bag to be thrown out. If the moss is too small to be knocked off by the broom, if its lower than the shingle above it, then we leave it. When we treat the roof with our solution the moss and anything it is feeding on will die off, and over time crumble away. Another way we have found to be useful is just using our hand with a glove to scrape the moss off in highly visible areas. Neither the broom or your hand will void the warranty on your roof. You can certainly use other tools that do not damage your roof, but this is what we have found to be most effective.
There are lot of different types of moss and a lot to know when maintaining a home. Here are some fun facts about moss in the Pacific NorthWest!
• There are over 10,000 species of moss worldwide. The top three that you may recognize on your roof are, Roly-Poly moss, Spindly Moss and Furry Moss. Each of these can do damage to your roof, but if taken care of properly, can be avoided throughout the year in the Pacific Northwest.
• Moss does not have roots. Moss belongs to a group called Bryophytes which means that anything part of this groups has no roots, leaves or stems. This group is are flowerless plants that grow in clumps. With no stems or roots to soak up water, you will find them in moist places so they can continue to grow.
• Moss is anchored by rhizoids, which look like tiny roots. Rhizoids are a thread like structure but do not absorb water or nutrients.
• Moss gets its nutrients from rainwater, dew, fog, and sunlight. They may get nutrients from the top layer of soil if they are touching it.
• Mosses do not produce pollen, seeds or flowers. They have a gametophyte (also called spore). This spore has their own stem, which grows and then off that, they grow buds, and that is how moss reproduces.
