What project are you planning?
Start by separating three different needs: renewing an existing roof, roofing a new structure or improving a roof that will largely remain. Each calls for different information. An existing leak needs diagnosis; a new building needs a coordinated design and specification.
Choose the appropriate branch
Pitched roof replacement introduces tiles, slates and supporting timber considerations. New roof projects covers extensions, garages and new builds. Roof improvements focuses on insulation and roof windows. Flat roof renewal and system comparisons have their own branch.
Decisions that shape the roof
The covering is part of a larger assembly. Roof form, supporting structure, insulation, ventilation, drainage and junctions must work together. Appearance matters too, especially where the roof forms a prominent part of an older property.
Plan assessment and coordination
Existing-roof projects benefit from a condition assessment; new projects need drawings and clearly assigned design responsibilities. Check planning and building-control requirements for the actual property and work. Include safe access, temporary protection and coordination with other trades in the discussion.
Prepare a project enquiry
For renewal, gather roof history and known defects. For a new project, prepare available plans and explain the stage reached. Set out your priorities so quotations can address a defined scope rather than a covering material alone.
Your questions, answered.
How do I know whether my roof needs replacing?+
Condition and the extent of defects should support the decision. Ask how repair compares with renewal for the actual roof.
Where should I start for an extension roof?+
Start with the extension design, roof form and junction with the house; the extension page explains the main coordination points.
Can improvements be planned during roof replacement?+
Yes. Insulation, ventilation and roof windows can be considered together, with the specification checked for compatibility.
