Identify whether the work concerns a gutter, flashing, dormer cheek or edge cover. Material cannot always be established from colour in a photograph. Ask what is present and proposed, including connections to retained components. Agree corners, dimensions and fastening. If appearance matters, record the intended profile and visible width before ordering or fabrication.
Identify the actual detail
Show whether the work concerns a wall junction, chimney flashing, gutter, capping or decorative element. An overview is more useful than the words new leadwork alone. It tells the roofer which adjoining parts are involved.
Assess material and surroundings together
Ask which material suits the detail and how it connects to retained roofing and masonry. Material selection, fastening and preparation form one proposal. Do not infer the correct replacement solely from the colour in a photograph.
Include corners and transitions
Ask how corners, joints, ends and changes of height are finished. A quotation listing only metres of metal may omit necessary detail work. Request an explanation of removal and reinstatement of surrounding components.
Agree the appearance
Discuss the intended profile, visible finish and relationship with existing ornaments or roof edges. Use a drawing or reference where helpful. Keep agreed design details with the quotation to make the intended result clear.
Add a description to the photograph
Mark the component in an overview and explain the complaint or desired change. Ask which adjacent parts need opening and how they are reinstated. A clear description helps define work beyond the visible strip of metal.
Make material junctions part of the scope
Where different materials meet, ask how the new work connects to the parts that remain. Specify preparation, fastening, corners and associated finishing. Keep completion photographs that show the junction in context.
