Can Moss and Lichen Damage my Roof?
A few spots of lichen or moss on your roof looks unsightly but probably doesn’t do too much damage, right? Wrong! Damage caused by lichen and moss is one of the most common roofing issues we are called out to fix.
Lichen in particular, when established, will do severe damage to Colorsteel or stone-chipped (Decramastic) roofs. Lichen is a growing plant that will root into the colour coating of your roof and strip it bare leaving the bare iron of your roof exposed to the elements and corrosion.
On concrete tile roofs, moss and lichen growth will open cracks in mortar work and block water channels causing leaks, leading to costly repairs.
We recommend regular roof cleaning, including a moss treatment be every 2-3 years. That way you can be assured your roof is giving your home or business the protection it should.
