Removing moss and vegetation from your roof as soon as you notice them is important.
Must be removed
There are several reasons for this:
- Moss damages your roof's shingles by discolouring them.
- An accumulation of moss will destroy your roof's ability to shed water properly. It starts to fill the keyways between shingles, which funnel water down your roof. When this occurs, water runs laterally rather than straight down and seeps under the shingles, leading to leaks and roof damage.
- If a homeowner doesn't routinely remove moss and vegetation from their roof, their shingle warranty will become void. CertainTeed, for example, in their Limited Warranty, "does not provide protection against, and CertainTeed will have no liability for, any failure, defect or damage as a result of, including but not limited to:...Shading, stains or discoloration to the shingles arising from outside sources such as...fungus, moss, lichens or other vegetation, mold or mildew growth, or paints, chemicals or other similar materials."
So it is important to remove moss as soon as you see it. Unfortunately, moss doesn't take long to grow in our wet climate.
Has to be dry
Summer is the best time to remove moss from your roof, but as long as there is a period of dry weather, it can be done.
Non-toxic compound used
We use a non-toxic spray to kill the moss. When it is done, the moss must be fully dry. Also, the compound needs a few days of dry weather to do its job thoroughly.
