Main roofs, additions, and low slopes
An Alberta Arts District roofing bid should identify whether it covers the main house, a porch, an addition, or a detached structure. Ask for separate measurements and installation details when roof slopes differ. A product suitable for the main roof may not suit a low-slope addition.
For a low-slope area, compare flat-roof installation details for drainage, edge transitions, and penetrations. If you are replacing an entire roof, ask the replacement contractor to explain how the new assembly connects to the adjoining roof and walls. Request photos of those details before the crew covers them.
Check permits for the property and work
Use the permit planning guide to identify the information your permitting office needs. Confirm the jurisdiction, building type, proposed material, structural changes, and any solar work. Ask about historic or other property-specific reviews separately. A neighborhood name does not establish the fee or approval schedule.
Compare bids with the same scope
Use the Alberta Arts District quote worksheet to organize contractor estimates. Compare quantities, exclusions, hidden-damage allowances, and access costs before comparing totals. A price from another house may cover a different roof assembly or amount of work.
Check who will perform the work
Before choosing a contractor, match the business name on the bid to its license record. Ask who supervises the installation, how changes need approval, and who handles warranty calls. This site provides information and referrals; the contractor is responsible for the work you agree with them.
