Ontario Contractors costs – Roof


As property inspectors, under the terms of our code of conduct, while we may have the skills, we cannot perform work to rectify issues we might have identified in any of our inspections.

Likewise we cannot recommend individual contractors to work on these remediations, but are happy to give you a list of local contractors we know of that specialise in the area of work needed.

For your benefit, and to judge whether you are getting a good deal from your contractor we have posted a series of pages that identify the average Contractor cost for different types of work so you can compare prices.

Remember, the best is not necessarily the cheapest nor is the most expensive.  It is up to you to ensure the contractor has the adequate qualifications to work on your property, and you should always ask for references, and make sure they are both insured and not on the complaints list of the Better Business Bureau.

labour (+ 10 %)

Flashing

It is advisable to replace all roof flashing at
the time a new roof is installed. The cost of installations at that time is
minimal, compared to possible problems old flashing may cause if they
remained. Counter flashing may be installed at any time over existing step or
chimney flashing and can be colour coordinated to a homes exterior.
