Describe the existing roof
ANME’s guide covers the building envelope, including roofs. Before comparing prices, have the substrate, possible leaks, area and terrace use described.
Compare equivalent solutions
Ask for material, thickness, declared performance, preparation, junctions and final protection. Thermal insulation and waterproofing serve different functions; material price alone is not the full job cost.
Plan handover
Specify roof access, waste removal, warranties and inspection. If a grant is mentioned, confirm current eligibility with the responsible body before including it in your budget.
Useful questions
Is the cheapest quote necessarily best?
First compare quantities, material references, preparation, installation, taxes, waste and warranties. Request details for missing items. The tool calculates differences, not a guaranteed fair price.
