Sometimes we get up on a roof and find that it just can’t be helped. But that doesn’t always mean you have to replace it right away. If we tell you to leave the roof alone, that means you probably have a couple more years left, as long as you don’t touch it.
I went out to a client’s home this week and climbed up on the roof. It had moss and lots of slime trails; it looked pretty bad. But it also had what’s called spider cracking. That’s where you have little fracture lines all over the shingles. If we were to try and clean that roof, they would start losing granules and it would loosen the shingles. Rather than getting the next three to five years out of it, they’d have to replace it in the next year.
So I called them up, said, “Listen, we need to leave the roof alone. Don’t touch. Don’t do anything to it.” And you know the response I got from them? “Well, none of the other roofers said that. I don’t understand why you can’t clean it.”
I don’t know why other roofers would tell someone something that’s not true. Sometimes it’s best to just leave your roof alone, deal with the look of it, and get the longest life out of it that you can.
