How do I stop moss growing on roof shingles and tiles?

Moss and algae growing on roof shingles and roof tiles can be unsightly, not to mention damaging. Left to grow and embed itself, these types of organisms can cause thousands of pounds of damage as they cause your roof to become unstable and degrade. This is easily treatable with zinc or copper strips. For their inexpensive price and low environmental impact, seeing as copper is the third most recycled metal in the world after iron and aluminium, copper strips are the most effective and cheapest way to do this.

Adding a 2-inch thick strip of copper across the ridge of your roof as close to the pitch as possible will protect roof shingles and roof tiles from growing moss. If your roof is larger than average then you might need to fix more than one strip, putting a copper strip at the midway point down the roof too. When it rains the copper salt will be washed down the roof from the strips you’ve fitted and will coat the roof. This then prevents moss and algae from growing.
