Roofing quotes can differ because contractors may recommend different materials, preparation work and repair scopes. Compare written scopes line by line and ask how the proposed system suits the building and Calgary weather.
What to compare
Review materials, underlayment, ventilation, flashing, disposal, site protection, warranty terms and the process for approving hidden damage. Confirm whether related work such as gutters or insulation is included.
Document the condition
Share the roof age if known, leak locations and recent storm damage. Photos taken safely from the ground or inside the attic may help. Avoid climbing onto a damaged or icy roof.
