What’s Wrong With Roof Moss? Part 2

Aerial View

If you thought the roof moss problem we showed on Monday was bad then you’re in for a surprise today! Today Patrick D. Morin takes us over to the Northeast side of the home to show us where the real roof moss action is happening.


This is what I’m talking about when I say you let the moss get serious on here, this roof will fail 2 to 3 times sooner than it should just because they’ve let this moss form in these keyways and it will get underneath that shingle and it will lift it up, remember these shingles are designed to traffic vertically, running up and down the shingle, actually down the shingle, they are not designed to handle water trafficked horizontally on the shingle. Moss, debris, buildup, tree debris, and stuff like that, will actually cause the water to travel horizontally and find fasteners and get into the structure.

Don’t let your roof moss problem get to this point. Your architectural shingle roof should be inspected once every three years to ensure it’s functioning properly. If you can’t remember the last time a roofing contractor looked at your roof it’s time to take Roof Life of Oregon up on its free roof inspection offer.
