BURNABY & NEW WESTMINSTER
Burnaby is another area with medium to heavy moss growth. There is also an abundance of yellow lichen near the waters of Burrard Inlet and is found mostly on the concrete tile ridges. We have worked all over Burnaby, which commonly features concrete tile roofs that tend to see large, rolling balls of moss along the tile edges and ridge caps. Asphalt roofing, on the other hand, sees sprawling growth all over the surface and ridges, as well as following the shingle lines where roots penetrate the surface. The City of New Westminster features many asphalt shingle roofs with slightly less moss than the average concrete tile in Burnaby. However, most roofs in New Westminster also contain more dark and ugly algae streaks, requiring roof cleaning all the same.
