A reliable price for your roof requires information about the building and the scope of work. Area matters, but so do access, components to replace and details to rebuild. Ask for a written description that is specific enough to compare proposals fairly.
Give every contractor the same starting point
Provide the same address, building type, observed problem, available access and requested work. Mention rooftop equipment, occupied units and related projects. Keep a copy of this request. If one proposal covers full replacement and another covers a limited repair, the difference in totals says little about which proposal fits your needs. A shared starting point makes later questions much more useful.
Read the inclusions before the total
Look for descriptions of removal, disposal, decking, insulation, the covering, connections and drainage. An item may be included in a package; simply ask for its scope to be described. Also clarify protection around the home and cleanup at completion. The goal is not to obtain an installation recipe. It is to understand the expected result and which existing components will remain in place after the work.
Define how unknown conditions will be handled
Some materials are not fully visible until the assembly is opened. Ask how a discovery will be documented, who will approve additional work and how the cost will be calculated. An allowance, unit price or exclusion should be understandable. Also clarify taxes, payment stages and postponement conditions. Keeping these items in one comparison sheet makes it easier to discuss differences without overlooking an important assumption.
Compare the follow-up as well as the work
Identify your contact before, during and after the project. Ask which documents you will receive and how to raise a question. Quebec’s consumer protection office recommends detailed estimates and checking the contractor. For your own decision, also record what remains unanswered. A clear proposal helps your household plan spending with fewer unknowns. This guide prepares the comparison; it does not replace a building-specific estimate or serve as installation instructions.
Your practical checklist
- Use the same address, scope and assumptions.
- Identify the components being retained and replaced.
- Define approval and pricing for additional work.
- Clarify taxes, payment, scheduling and completion documents.
Frequently asked questions
Why not use one price per square foot?
That number can hide significant differences in access and scope. A tailored estimate should explain what makes up the proposed total.
Should I choose the lowest estimate?
Price is one part of the decision, alongside scope, responsibilities and the answers you receive. First compare equivalent proposals, then choose according to your priorities.
