Structural engineers / post install inspection

[Ted Morrison]

I'm in the process of trying to select a roofing contractor to replace my cedar shake roof. I've received a number of bids, compared the companies to BBB and the state registrar of contractors, getting references as well as insurance info etc.

Depending on the type of roof that I go with (probably concrete tile), I may need to get a permit from the city, and possibly an engineering report for the structure.

The roofing contractors that I've talked to have given me a wide range of the cost of an engineering report ($150 - $700). That seems like a really wide range. What is a typical cost for a good engineering report? Should I get an independent engineer, or should I work with the ones that are recommended by the roofing contractor?

Also, how typical is it to get a roofing inspector to come out and take a look at the quality of the work that's being performed by the contractor? I understand this would be over and above the cost on the contract, but I wouldn't mind paying extra for the peace of mind of knowing that someone more knowledgeable than me is looking at the work done and giving his thumbs up / down (and that this person is not biased towards the contractor).

Thanks for the advice.

With that price range differential I would hire my own engineer. If you are required to get a permit, then it will be inspected (or should be). Call your local permit center and ask how thorough their inspection is and what they are looking for in an inspection. Good luck with your project.
