Cedar shake roof treatments?
I was talking to a roofer about what to do with our ~25 year old cedar
shake roof and one option he offered was a "restoration" consisting of pressure washing the existing shakes, replacing all damaged shakes and felt, and spray-on treatment with a derivative of guanidine phosphate, which is supposed to be UV protective, and decay and fire retardant. They offer a 12 year warranty on the treatment. Are these chemical treatments effective for older roofs? The quoted price seemed potentially attractive compared to a new shake roof, but not exactly cheap ($6K for 2700 sq ft). Maybe most of the value of the "restoration" comes from the repair work? -- Dave |

Is the roof leaking? Tom Not as far as I can tell. But there's quite a bit of visible damage (split/decayed shakes, etc). I'm not really clear on how one tells when a shake roof is at the end of its useful life. When we bought the house a year ago, the roof inspection report indicated that the roof had 1-2 years left. Another inspector maybe 6 months ago said the same thing. We had minor repairs done at that time. -- Dave |
