PW McCALLUM ROOFING REPAIR

Moss on my roof! Is it a problem? The answer is most often yes, moss roots itself into the granules i.e. rocks on asphalt roofing. The environment on Vancouver Island is optimum for the growth of moss and algae and molds.  On roofs that we have installed in Victoria and Duncan B.C. we have found the moss will start growing within 10 years on A.R.

This however is untrue as there is over a thousand species of moss no manufacture can claim they can stop moss.  A.R. “resistant” please read more at   http://www.pwmccallum.ca/moss-removal.php
