Consider the specific municipality

Requirements for replacement work should be checked for the exact property address. Mention any steps already taken and documents you have available. Do not assume that a requirement in a neighbouring municipality applies in the same way to your building.

Coordinate the people involved

For a condominium or rental building, identify the decision-maker and the person who can provide access. Explain occupancy periods and any required approvals so the proposed scope can be discussed with the right people before planning work.

Explain your priority

Replacement, a leak, maintenance or drainage: describe the main need and your preferred timeframe. The team can then confirm available options and any additional information required.

Prepare your request

Share the building address, the issue you have observed and the roof type. We can discuss the information needed and options for a visit.

Roof repairs and water infiltration assessment

A ceiling stain does not always reveal where water entered. Planning an effective roof repair starts with understanding when the leak occurs and examining the relevant details. Describe the problem to Alliance Roofing so we can help identify the next step.

Roof flashing, parapets and connections

Roof junctions deserve as much attention as the main surface. Plan an assessment of flashings, copings and penetrations for a coherent waterproofing system.
