Identify the roof sections, dormers, windows and chimneys included. Ask what happens to underlay, battens and connections beneath or beside the tiles. Confirm the tile model and matching fittings, using samples if useful. Include access equipment, disposal and protection in the plan. Agree how transitions to adjoining roofs are treated and what completion photographs will be provided.
Record the current roof
Keep overview photographs showing the roof planes, ridges, verges and dormers. Explain whether you want to preserve the appearance or change it. Photographs support discussion but do not replace on-site measurements and assessment.
Discuss the layers underneath
Ask which underlay, battens, counter-battens and supporting parts remain or are replaced. Some findings become visible only after lifting tiles. Agree how concealed damage will be documented and approved.
Compare a specific tile proposal
Ask for the proposed model, profile and colour, including matching fittings. Check how it relates to the roof shape and existing details. A photograph of a colour does not specify the entire roofing system.
Include work at the edges
Discuss ridges, verges, gutters and connections to chimneys or dormers. Ask which access equipment and disposal are included. Make clear whether adjacent metalwork is renewed or retained so the scope remains complete.
Identify what remains hidden
Have retained layers named in the proposal. Ask what can be inspected at the first visit and what is assessed during opening. Keep photographs before new tiles conceal repaired or replaced components.
Judge the appearance as a whole
Include ridge tiles, verge fittings, corners and dormer transitions when reviewing the design. Discuss a sample where useful. Keep the final material selection with the completion record for future replacement or maintenance.
