Hi, I'm Tim Carter from AskTheBuilder.com. Look at this horrible moss on my garage roof
0:14
It's gross, it's horrible. And you know what, it can cause the shingles to fail prematurely
0:19
but I want to show you something you're not going to believe. Come with me. Okay, I walk just 10, 12 feet away and look at the shingles on this part of the garage
0:34
roof. There's no moss, there's no algae, they look really, really pretty good for being
0:41
20 years old. Now why is it that these are clean and those aren't? Well, I'm telling
0:46
you right now, it's not because I took the moss and algae off. Let me show you how Mother
0:49
Nature did it for free. Here's a copper cupola that's right on top of my roof. It's this
1:00
little itty bitty roof And every time it rains a little bit of this copper washes off the roof and goes down across the shingles And that copper creates a poison so that the moss and algae won grow
1:15
It's much like weed killer that you might put on your lawn. So if you don't want moss or algae to grow on your roof, you can put copper up on it
1:22
You've got two choices. Put copper strips underneath the cap shingles at the top of your roof, only with about two
1:29
inches or three inches of copper exposed. Or if you're buying a new roof or building
1:34
a new home, you can actually buy shingles that have copper that is incorporated into
1:39
those colored granules. It's that simple. I'm Tim Carter for AskTheBuilder.com. If you want to discover more home improvement tips, go to AskTheBuilder.com
