Are you shingles covered with moss? This shingles in this garage roof section are covered with green moss growing everywhere. Roof moss can cause the shingles to fail prematurely, besides looking gross.

But the roof just ten feet away is clear of any moss or algae! Why are these shingles clean and the others are not? Not because they have been cleaned by Tim. Mother Nature did it. For free!

Above the clean section of the roof, there is a copper cupola. It is this little bitty roof that is keeping the moss off the roof. Every time it rains, a little of the copper washes off the cupola and onto the shingles. That copper creates a poison so that the moss and algae will not grow, must like a weed killer who use on your lawn.

If you do not want moss growing on your roof, you can put copper on your roof. Just place copper strips underneath the cap shingles on your roof. Leave 2 - 3 inches of copper exposed so the rain can wash copper particles down over the shingles. Or if you are buying a new home or having a roof replaced, there are shingles with copper embedded right in the shingle.

Using a little copper on your roof can prevent moss and algae from growing. It is just that simple.
