If you’re reading this, you’re probably annoyed that your home is beginning to look like it’s part of the woods, with moss and algae growing on the roof. Elite Remodeling Services can assure you our roofers seen this on many residential properties with all kinds of roofs. It’s a fairly common problem, but well worth checking on and cleaning to avoid uniting your home with nature on a damaging level!
Why do I have moss and algae on my roof?
Nature was here first! If you are living in an area with high humidity, it’s the perfect environment for moss and algae to grow and spread like a carpet. The algae will look like dark, streaky patches, and the moss will look like a soft, furry carpet.
How to get rid of moss growth
Moss grows where it’s shady and, in those areas, you either need to clean off the moss or remove the shade. If the shade is provided by a tree next to your house, prune the overhanging branches because they are the culprits dripping life-giving moisture onto the growing moss carpet. Your other option is to remove the tree entirely.
Cleaning method: Get yourself a ladder, a hose, and a cleaning solution. Start by rinsing your roof. Do not use a power washer, because it will damage the shingles and void your warranty. Just use the hose. Then, choose your cleaning solution (there are various ones available) and start applying from the top. Take a soft roof brush and gently brush off the moss from top to bottom, small areas at a time, taking care not to damage the shingles. When you’re done, rinse off the roof and let dry. If your roofs is too damaged, you may need a complete roof replacement.
How to get rid of algae growth
Algae is a bit more of a challenging problem. If you’re replacing your roof, one option is to choose copper composite shingles. It’s a new invention, containing copper that is toxic to algae, thus preventing its growth. An expensive investment, but worthwhile if you can afford it.
A cheaper and less laborious option is to put metal strips on both sides of your roof at the edges. Here’s how it works: when it rains, metal particulate is spread over your roof, promptly killing off algae all the way.
Cleaning method: As with the moss, start by rinsing the roof from top to bottom with the hose, and then apply your chosen cleaning solution from the top down. Brush with a soft roof brush, small areas at a time. Cleaning off the algae may take longer than cleaning moss. Take it slow and gentle. When you’re done, rinse off, and let it dry.
How often do I need to get algae and moss off my roof?
On average, one clean a year is enough.
