Moss grows in cold and humid environments. If you have moss on your roof, it's probably because the roof is shaded by trees or other structures, allowing moisture to stay and moss to grow. Shaded areas exposed to frequent cold and humid weather will quickly stimulate moss growth on the roof. The presence or absence of sunlight determines the amount of moss or algae growth.
On asphalt or possibly on some (treated) wooden tile roofs, the chemistry of shingles is also involved in the growth or resistance of mosses, lichens and algae. Some shingle materials contain algaecides or fungicides, which also slow the growth of moss on the roof surface. When debris, such as large branches, accumulates on the roof, debris can also cause water to build up. Water, together with shade, are the two elements necessary for moss to grow.
If you ever see a large branch or other debris on the roof, remove it immediately. Moss spreads by releasing spores like many plants. Moss growth is much more likely on damp, cold surfaces that don't get much sunlight. This makes north-facing tile roofs especially prone to the accumulation of moss and algae, as they can quickly take root in the dark nooks and crannies between and below shingles, shingles, or slates.
Shingles made of clay or concrete are particularly susceptible to moss growth. This is because their porous surfaces and frequent exposure to rain and moisture make them the perfect environment for moss to take root and spread very effectively. This method is suitable both for preventing the future or future growth of moss or lichens on the roof and for gently treating an old roof that would otherwise be fragile. There are numerous ways to remove moss from your roof, depending on the importance of dispersion.
After reviewing these details, you might be ready to fight moss on your own, or you're sure you need to look for a professional moss remover in Vancouver. Homes with multi-level roofs have a higher risk of moss formation because the gutters in the upper roof often drip to the lower roof, creating a perfect home for moss. Moss will not only make the roof look quite unsightly, but it can also cause structural damage and block the house's drainage system. Moss and lichens are more than just a cosmetic problem in many types of roofing materials: asphalt shingles, rolled roofs, wooden tile roofs, wooden batten roofs.
Fortunately, removing moss is a fairly simple task that you can do depending on the season or as needed to keep your roof airtight and looking good.
