In this episode, Patrick discusses why the pH balance of your roof is important- especially in areas that get a lot of rainfall. Hint: it has to do with moss…

Shayla: You are listening to the Roof Life of Oregon podcast and I’m talking with CEO Patrick Morin. Patrick, why do you guys talk so much about the pH health of a roof? What does that mean?

Patrick: Well, we found out through the manufacturer starting the education process and then watching it over the last twelve years is that if you can control the pH level on a roof, keeping it neutral to slightly alkaline, the moss and black rot fungus do not like that environment. They can’t exist there so they grow on someone else’s roof that isn’t pH balanced.
When our products go on, they take a very acidic environment, the roof, and they make it neutral, slightly alkaline. And alkalinity is anything above a seven on a scale of fourteen. So a pH scale is zero to fourteen. A seven is neutral. Anything above a seven is alkaline. Anything below a seven is acidic. So if we just say that six to eight is somewhere in the middle, what we want to do is keep it above seven, and you’ll be able to control the growth on your roof. Now we live in the state of Oregon, and we’re on the west coast, and so we have developing Asia and the way the trade winds work is that big swirl that happens out there in the middle of the Pacific gathers up the environment from over there and brings it right up the west coast, Northern California, Oregon, Washington, British Columbia. So we’re getting quite a bit of carbon monoxide mixed in with the H20, and it is dropping on us in what we would call acidic level rain.

I don’t think it’s as bad as what people call acid rain, like it’s going to corrode and burn you, all that stuff, but it’s definitely in the fives. So when you have a treed environment, both fur trees, cedar trees, and then all of your broad leaves, these trees along with our rain are making it really tough on these roofs to keep the moss from developing and ruining the roofs, not just visually. We know that’s what you see and, oh, man that looks horrible. You’ve got a beautiful paint job, a nice roof that’s now ruined by moss, but it literally grows under the shingles, lifts them off their weather stripping, and the water that’s trafficking downward by gravity is going to move side-by-side with the developing moss and get to your fasteners. That is going to saturate your plywood and cause you a premature failure in your roofing and new plywood to be put on. So this is a big dollar issue of not letting that happen. So when we come out every three to five years, if you have a really treed environment, every two to four years, and we apply our products, we’re controlling the pH of that roof, so moss and black rot fungus cannot develop and start to decay and infiltrate how the roof is put on. So pH balance to Roof Life is a big deal and we use the Dennco products that control the pH and that’s why you’ll hear us talk about the pH of the roof is really important.
