Ottawa Roof Replacement Cost Guide
The useful way to compare roof replacement pricing is to compare the complete roof system and the assumptions behind it. Roof area, pitch, existing layers, sheathing, penetrations, flashings, ventilation, access, and weather all matter.
Main cost drivers
- Roof size, pitch, access, and number of existing layers
- Underlayment, ice-and-water protection, ventilation, flashings, and penetrations
- Sheathing or structural repairs discovered after tear-off
- Material grade, disposal, site protection, seasonal timing, and cleanup
Plan before comparing quotes
- Request an inspection that identifies the roof system, not only the finished shingle.
- Ask for separate assumptions about tear-off, sheathing repairs, flashings, ventilation, and waste.
- Confirm warranty documents, weather-delay procedures, protection of landscaping, and final cleanup.
