Roofing for Extensions & Loft Conversions
Building out or going up? We roof new extensions, dormers and loft conversions — and tie them into your existing roof so it all looks like one.
An extension or loft conversion changes the shape of your roof, and that's where the skill is. The new roof has to shed water, the join to the old roof has to be watertight, and the whole thing wants to look like it was always there. Get the roofing wrong on a build and you'll be chasing leaks for years.
We roof extensions, dormers and loft conversions across Hampshire and Surrey, and we alter existing roofs when a layout changes. We work alongside builders and homeowners, tie new roofs into old ones cleanly, and match materials so the join disappears. Whether it's a flat-roofed side return or a pitched dormer, we make the roof part of the house, not a bolt-on.
What We Do
Extension roofs (pitched and flat)
New side returns, rear extensions and orangeries — we roof them in tile, slate or flat systems to suit the build.
Dormer roofs
A dormer adds headroom and light to a loft. We roof and flash dormers so they're weatherproof and tidy.
Loft conversion roofing works
From cutting in a stairwell to opening up the roof, we handle the roofing side of a loft conversion.
Roof alterations
Changing the roof shape, raising a ridge or adding a hip? We alter existing roofs to suit a new layout.
Tying new roofs into existing ones
The join between old and new is where leaks start. We tie new roofs into existing ones with proper flashing and matching materials.

Questions We Get Asked
Yes — and it's one of the most important parts of an extension. The junction where the new roof meets the old is where water always tries to get in, so we detail it with proper lead flashing, valleys and soakers rather than just butting them together. Done right, the join is both watertight and invisible from the street.
