Hey all, looking for some advice. I’m in BC Canada so we get a ton of rain. My shake roof is around 20–25 years old, maybe more. It looked mostly fine, but I just redid my siding and had a bunch of guys walking all over the roof, so I figured I’d give it some TLC.

Found a company that’s been around a while (good reviews, BBB since the late ’90s) to clean, repair, and treat it. They’re giving me about an 8-year warranty. Not cheap, roughly a third of what a reroof would cost.

They said they’d clean, repair, then treat, but ended up cleaning, treating, and then repairing. Bit backwards, but whatever.

What’s bugging me is they power washed it. Everything online says don’t power wash shakes. I asked the guy before he started and he said it’s medium pressure, no big deal. He’s the pro, so I let him go ahead.

Near the end of the day my kid comes in from the garage (he plays hockey in there) and says water’s coming in.…
