Roofing a new extension is a slightly different job to a standard re-roof, since it has to integrate properly with the existing house — both visually and functionally. Here's what Back to Back Roofing Worcester considers on every extension roofing project.
Why Extension Roofing Needs Particular Thought
An extension roof isn't a standalone structure — it has to tie into the existing roofline, manage drainage without creating new problems, and often work within tighter design constraints than a full re-roof of the whole property.
Common Extension Roof Types
- Flat roofs, common for single-storey rear extensions
- Pitched roofs matching the main house roofline
- Lean-to or mono-pitch designs against an existing wall
- Combination designs incorporating roof windows for extra light
What Genuinely Matters for Extension Roofing
- Matching materials to the existing roof where visual consistency matters
- Proper drainage design so water doesn't pool or discharge against walls
- Correct junction detailing where the new roof meets the existing structure
- Building Regulations compliance, since extensions have their own requirements
How We Approach Extension Roofing
- Assess the extension design and existing roofline. So the new roof integrates properly, not as an obvious add-on.
- Recommend appropriate materials and design. Balancing your preferences with what genuinely works for the structure.
- Plan drainage carefully. New roof areas change how water moves around the property.
- Ensure compliance throughout. Including Building Control sign-off where required.
Benefits of Getting Extension Roofing Right
- A roof that looks like it belongs, not an obvious bolt-on
- Proper drainage that doesn't create new damp problems
- Compliance with current regulations, avoiding issues later
- A genuinely weathertight addition to the property
