Full roof replacements in Keynsham and the surrounding BS31 area. Concrete interlocking tile, Welsh slate, and clay tile re-roofs. 10-year written guarantee. Free itemised quotes.
A full re-roof is the right call when repairs stop being economical — when fixings have failed across the whole slope, the underlay has perished, or you're throwing good money at a roof near the end of its life.
Slates slipping repeatedly across the whole roof, not just one spot
When it is not the answer: If the slate itself is sound and only the fixings have gone, a strip-and-relay reusing your original Welsh slate is often better value than a full replacement — and keeps a heritage roof authentic. Read the full guide.

Roof Replacement in Keynsham
Roof Replacement Keynsham
A significant proportion of Keynsham's housing stock is now at or approaching the age at which full re-roofing offers better long-term value than continued repair. 1970s to 1990s concrete interlocking tile roofs on the major residential estates around Somerdale and the BS31 suburbs are typically 30 to 55 years old. Roof replacement at this age, before the underlying felt and batten begin to fail, avoids the higher costs of emergency repair and water damage associated with allowing a deteriorated roof to continue in service.
Re-Roofing Options for Keynsham Properties
For the concrete interlocking tile estate housing that forms the majority of Keynsham's stock, we re-roof in matching concrete tile profile or upgrade to modern concrete or clay interlocking. For Victorian terraces in the town centre, full Welsh slate re-roofing with lead soakers and new Code 5 lead valleys is the correct approach. We provide fully itemised quotes covering materials, scaffold, skip hire and all associated works.

Access
Getting Safely onto Keynsham Roofs
A full re-roof always needs scaffold for safe working and to protect you and passers-by; it's included and itemised in your quote. Scaffold is specified for: the entire job — full perimeter scaffold is standard on any re-roof - always itemised in your written quote, never a hidden extra, and we arrange it.
Keynsham's Victorian terraces and 1930s semis off the High Street need tower or scaffold access; the town centre has controlled parking. Pavement scaffold and skip permits go through Bath & North East Somerset Council; allow a few working days on streets like High Street, Temple Street, Bath Hill where space is tight.

Staged payments on re-roofs — nothing up front before materials are on site, a payment at strip stage, balance on completion. Re-roofing an existing home usually qualifies for reduced 5% VAT, confirmed in writing at quote stage.

Guarantee
Your Guarantee, Explained
The complete re-roof carries a 10-year workmanship guarantee in writing; slate, membrane and other materials carry their own manufacturer warranties on top.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Good to know
What It Is Like While We Work
A re-roof means scaffold up for the duration, skip on site, and some noise during the day — but external work rarely needs you home, and we protect your garden and drives throughout. You do not need to stay home for external work - we just need power and access agreed in advance.
We never strip more than we can make watertight in a day, and temporary covering goes on every night, so your home stays protected throughout. Sitting between the Avon and Chew valleys, Keynsham holds river-valley damp that accelerates moss on shaded roofs.
