roof certification
Hi all
Just starting in the home inspection business. I did a roof certification today on a 67 year old barrel tile roof. Roof was sealed with waterproof material and maintained over the years. No missing or damaged tiles. No signs of water damage or leaks to the decking. What should I say in the report about remaining life expectancy. Any suggestions.
Thanks Ron

Re: roof certification
Replace roof, no remaining life expected.
The roof may continue to limp along without the current leaks visible for another few days, weeks, or years, but the actual waterproof layer under the tile had a life expectancy of 20 to 30 years at most.
At 67 years old it was installed in 1947 ... think about the organic felts used in 90 pound roll roofing back then - shortly after the war years which had rations on everything, especially oils (asphalt and other chemicals).

Re: roof certification
Say nothing about life expectancy. The roof was performing today with no evidence of leaking or other failure.
If you choose not to decide, you still have made a choice.

Re: roof certification
Sorry I didn't back with you' having computer problems. Thanks for our your help.
Jerry thanks for the advice. I did notice a sag in the roof. When I mentioned it to the homeowner she said that's been there for several years now and the roof was inspected 3years ago and that inspector didn't mentioned it. The sag is very noticeable. 67 years its time for a new roof.

Re: roof certification
Ron,
This is the way I used to explain it to my clients: That clay concrete tile will be found in the archeological dig in 5,000 years ... it's the waterproof layer under the tile which will not leave a trace in that dig ... it'll be leaking in 20-30 years from new and almost nothing of it will be left in far less than 100 years.
