Connection to the house
Abutments, cavity trays, flashings and existing openings must be coordinated so the new roof does not create a weak junction.
Roofing
Roofing for extensions
An extension roof has to resolve height, drainage, daylight and the junction with the original property while supporting the room planned below it.
Photos, drawings or a short description can help explain the current condition.

What the work needs to resolve
The roof form should be selected early because it affects wall heights, structural spans, rooflights, rainwater positions and the appearance seen from the house and garden.
Details to inspect before work starts
Internal character
Ceiling height, rooflights and structural depth shape the space below and should be decided with the room layout.
Rainwater
Gutters, outlets and discharge points need a route that does not simply move water onto a future landscaping problem.
What to mention
What to show or describe before work starts
- Describe what is already known about connection to the house.
- Explain the priority or constraint around internal character.
- Include enough context to discuss rainwater without assuming a product or method before the property is understood.
Questions specific to roofing for extensions
Can an extension have both pitched and flat roof areas?
Hybrid solutions can work where height or daylight constraints demand them, provided the junctions and drainage are properly detailed.
When are rooflights ordered?
After sizes, positions, kerbs and structural openings are confirmed, but early enough to protect the programme.
Should the roof match the house?
Material and form should respond to planning, availability, pitch and the intended appearance. Exact matching may not always be possible with aged materials.

Chimney repairs
Chimneys combine exposed masonry, leadwork, pots, flaunching and roof junctions, so repairs should consider the stack as a complete weathering detail.

A replacement roof is a significant project that should account for structure, coverings, insulation, ventilation, access and the condition revealed during strip-off.
