Use an overview to identify the upper and lower roof surfaces, dormers and gutters. Ask how the change in pitch is treated and whether adjoining sections are included. Dormer sides and roof edges need their own scope. Agree the intended tile appearance alongside access and scaffolding arrangements. Record how unexpected findings will be addressed when existing areas are opened.
Identify both roof planes
Use an overview to mark the steep lower roof and the upper part. Add dormers, gutters and adjoining walls. This clarifies whether the quotation includes the whole mansard or only one visible tiled section.
Discuss the change of pitch
The junction between roof planes is a distinct detail. Ask how it is treated and how adjoining retained parts are protected. It should not disappear into a general item for replacing roof tiles.
Include the dormer connections
A dormer interrupts the main roof with its own sides and edges. Clarify which parts are inspected together and which remain. A coordinated scope prevents connections being omitted between roofing and dormer work.
Plan appearance and access together
Discuss tile colour and profile alongside scaffolding, access and material handling. Agree how unexpected findings will be reported once the roof is opened. The visual proposal and execution plan should describe the same roof sections.
Name each section in the quotation
Separate upper roof, lower roof, pitch transition and dormer details. Ask which layers and finishing belong to each part. This makes it easier to compare quotations without assuming that similar totals cover identical work.
Arrange access for every phase
Ask how the different slopes are reached during opening, installation and finishing. Discuss temporary protection and routes through the property. Access agreed for one section is not automatically suitable for all later work.
