Roof Replacements & Re-Roofing

A re-roof is the right decision when repairs have stopped being good value: tiles that have gone porous, underlay that has perished, battens that will not hold a nail, or a slate roof where the nails have rusted through. Done properly, a new roof covering with a modern breathable membrane should give you fifty years or more without major attention.

We strip the old covering, inspect and repair the timbers, lay new membrane and treated battens, fit the new tiles or slates with the correct fixings, replace all leadwork and ventilation, and leave you with a roof that is dry, ventilated and guaranteed.

Before and after: natural slate re-roof

Stripped to the rafters, insulated, re-membraned and re-battened, then slated with new lead to the chimneys. The full step-by-step is on our slate roofing page.

Warning signs

Repeated leaks in different placesEach repair fixes one spot while the rest of the roof keeps failing.

Perished underlayOld bitumen felt goes brittle and tears; visible from the loft.

Porous or crumbling tilesOld concrete tiles lose their surface and soak up water.

Nail sickness on slateSlates slipping one after another because the iron nails have corroded.

Sagging rooflineBattens or rafters have failed under the covering.

Heavy moss and ongoing repair billsA sign the roof surface has deteriorated beyond cleaning.

Materials and methods

Tiles and slates from Marley, Redland, Sandtoft, Dreadnought and Cupa, matched to the house and the street. Breathable membranes rather than old-style felt. Lead to Code 4 for flashings and Code 5 for valleys. All fixings stainless or copper. We re-use original slates and clay tiles where they are sound, which saves money and keeps the character of a period house.

Why choose us for complete roof replacements

Everything under the covering renewed, not just the tiles
Fixing specification to BS 5534, which matters on exposed sites
Guarantees: our workmanship plus manufacturer guarantees on tiles, membrane and dry-fix systems
Scaffold, skip and disposal all itemised and included
Building control notification handled

What to expect

A survey from the roof and loft, photographs of what we find, and an itemised quote with options where sensible (for example, re-use of existing slates versus new). On site, the roof is stripped and re-covered in sections so it is never left open overnight. A typical semi takes one to two weeks. You receive photographs at each stage and a final set before invoicing.

Frequently asked questions

Will my house be open to the weather?

No. We strip and re-cover in sections and the roof is sheeted at the end of each day.

Can I change from concrete tiles to slate or clay?

Often, yes, if the structure can take the weight and the pitch suits the material. In conservation areas it is usually welcomed. We check both.

Should I replace the gutters at the same time?

Usually, yes. With scaffold already up it is the cheapest time to do fascias, soffits and gutters.

How much does a re-roof cost?

See our new roof cost guide for typical ranges. Every quote is fixed and itemised after a survey.
