Good roofing work
starts before
the first intervention.
A roof also depends on the things you no longer see once the work is finished. The substrate. The layers. The junctions. The path of the water.
Understand the condition. Inspect and ask the right questions before choosing a solution.
Define the scope. What the quotation includes and what remains open.
Coordinate the details. The build-up, outlets and finishes as one system.
A shared roof.
A clear process.
For apartment building renovation, scope and coordination matter: from preparing a quotation to protecting the building and handing over the completed work.

Location, roof type, approximate area and a few photographs. That is what we need for the first discussion.
Agree the solution.
An inspection, open questions and a clear scope. The quotation should state what it includes and the assumptions behind it.
Organise the work.
We agree access, building protection and work phases before starting.
Complete the handover.
A review of the completed work, agreed documentation and clear maintenance information.
Before the inspection.
Before the decision.
Prepare useful information about leaks and compare quotations on the same scope.
