Don’t….. fuckin power wash your roof. Don’t let anyone power wash your roof.
Friend, from the tone of your words, I feel like you’ve just learnt a hard lesson here…
Fortunately no, it was an easy lesson I learned when I was seven when my dad was power washing the driveway and I asked if he was going to power wash the roof next and he explained to me that it would damage the roof because it was meant to handle rain and snow, which is never going to be as hard as a power washer.
Lots of people are learning this the hard way this year though. It’s a new scam. Someone knocks on your door and offers to wash your roof for two hundred bucks. “Damn, that’s a pretty good price,” you think, knowing that roofs require a huge chunk of change. The guy power washes the roof and leaves. It was a cash transaction, and he didn’t leave contact information, so when your roof starts leaking during the first rain, you have no one to contact to sue for damages and you’re stuck on the hook for replacing the roof yourself, which you either do yourself (cost of materials and many hours of your time) or you hire someone to do for you (which runs into the tens of thousands of dollars, an amount people normally can’t just drop).
Lots of new homeowners don’t know this stuff, and it would definitely behoove them to research it, but until they have the time to do that, I’m here to say: Don’t power wash your roof.
