Compare the same job
Before comparing totals, check whether every proposal describes the same amount of work. Roof area is not the same as floor area. Pitch, height, dormers, valleys, chimneys, access and waste all influence the scope. Ask how the contractor measured the roof and which parts of the building are included.
Separate the base price from allowances
The condition of the roof deck may not be fully visible until the old roof is removed. Ask for a defined allowance or unit price for damaged decking, and a process for approving changes with photographs. Do the same for fascia, concealed flashing issues, insulation and other work that is outside the base scope.
A line-by-line review
| Item | What to confirm |
|---|---|
| Removal | Number of existing layers, tear-off, hauling and disposal. |
| Deck | Inspection, repairs, evidence and additional-work pricing. |
| Materials | Exact products, colours and assembly specification. |
| Water details | Valleys, walls, chimneys, drip edges and penetrations. |
| Airflow | How ventilation and moisture concerns will be assessed. |
| Closeout | Cleanup, final photos, warranty documents and contact details. |
Ask about occupied-property logistics
Delivery access, parking, waste bins and noise can be as important as installation dates. If equipment sits on the roof, confirm who coordinates disconnects, lifting and reconnection. For strata projects, identify the decision maker and how residents receive updates.
Read the exceptions
Look for exclusions, taxes, expiry dates, payment milestones and who is responsible for permits where needed. Resolve unclear wording before accepting a proposal. Keep changes in writing so the final invoice has an agreed reference point.
Review roofing cost factors and choosing a roofer before deciding. An online checklist helps organize the conversation; an on-site assessment establishes the actual scope.
