1. Establish what is already there
Identify the membrane or metal roof, previous coatings, approximate age and any known repairs. The condition of insulation and decking matters as much as the exposed surface. A visually worn roof and a moisture-damaged assembly are not the same situation.
2. Understand what restoration can do
On a suitable roof, restoration may retain useful materials while addressing specified defects and renewing the protective surface. It does not automatically correct trapped moisture, unstable materials, poor attachment or drainage design.
3. Understand when replacement enters the discussion
Widespread wet materials, deteriorated components or an assembly that cannot support the proposed system can make replacement necessary. A proposal should explain what is being removed, what remains and how concealed conditions are handled.
4. Compare equivalent information
A low headline price is not enough to judge a scope.
- Investigation performed and remaining uncertainties
- Removal, repair and preparation included
- Specified system and installation requirements
- Access, staging, schedule and exclusions
- Warranty provider, coverage and maintenance obligations
5. Ask what would change the recommendation
A good discussion identifies the conditions under which the proposed solution would no longer be appropriate. Ask how wet materials, adhesion problems or concealed damage would be handled before work begins.
A useful next step
Have the existing roof reviewed and ask for the reasoning behind the options. Keep the decision tied to the property, the findings and your ownership plans.
