There are several different types of roof moss. Some are grassy, while others are furry. There are also stagnant types. The good news is that there are ways to control the growth of roof moss. If you notice moss growing on your roof, you should take steps to remove it before it spreads to other areas. Before you give us a call at Western Construction & Roofing, be sure to read through this article to get to know your moss a little better.
Types of Roof Moss
Grassy Roof Moss
If your roof has a lot of grassy-looking roof moss, there are several methods you can use to remove it. Some of the methods involve spraying water to remove the moss. However, you need to be careful about the chemical residue you may leave behind, as it can damage your roof and washes away into the water table.
If you cannot remove the moss with a simple water spray, you can try a moss removal tool. Ensure that you wear protective clothing when working with the tools. Moss can get everywhere and cause skin, eye and respiratory discomfort, so it’s best to be safe if you want to tackle this project on your own.
Furry Roof Moss
Furry roof moss grows on damp, rotting wood. This type of moss is a sign of wet rot, which can eventually lead to a more serious issue – a roof replacement. If you suspect that your roof is in danger, you should take action to prevent it by setting up a roof inspection with us. A good roof cleaning regimen will help to keep the moss from growing too far. In particular, you should pay special attention to your flat roof, which often retains standing water.
Moss grows in the cracks between shingles, making it easier for water to get under the shingles and cause them to lift. This water can then seep into the roof framing, causing it to rot. Eventually, if you don’t take action to eliminate the moss, the process will begin again and cause a much worse problem. This process can take as little as a few months.
To remove the moss, you’ll need a ladder and a hose. Don’t use a power washer, as this can damage your roof shingles. Start by spraying a cleaning solution onto the moss with a hose, and use a soft roof brush to scrub it away. Make sure to rinse the entire roof thoroughly after each application. If the moss has grown too deep, you may need to replace the entire roof.
Stagnant Roof Moss
Stagnant roof moss is a problem that can affect a home’s appearance, as well as its structural integrity. Because it soaks up water, moss on a roof can cause the roof to collapse or even rot. It can also cause damage to gutters and stonework. However, moss buildup can be easily prevented.
The first step in preventing moss from growing on your roof is to clean your roof regularly. Moss grows in damp, shaded areas and it needs a substrate to feed on. This means cleaning your roof regularly and removing debris. You can also apply baking soda at the ridge line in the late summer. This solution raises the pH level of the roof, which is beneficial to preventing moss growth. If you have a particularly large amount of moss on your roof, you may want to apply more than one application.
Green Roof Moss
Mosses found on green roofs can damage roof tiles and shingles. They can also cause leaks and rot and mold. As these problems can be costly to repair, it is important to prevent green roof moss from developing.
