Roof Replacements

An ageing roof that's losing tiles regularly or letting water in is best replaced rather than patched. We carry out full roof replacements across Diss and South Norfolk, stripping back to the structure and starting fresh. You'll get a watertight, long-lasting result with a proper guarantee.

What's involved

Roof Replacements in your area

Roof replacements are necessary when ongoing repairs are no longer cost-effective — typically when the underlying felt has failed, tiles are brittle and slipping repeatedly, or the roof timbers have been compromised by long-term moisture ingress. Many properties in and around Diss have roofs that are forty or fifty years old, and at that age the felt and fixings are usually at the end of their useful life even if individual tiles look sound.

We strip the roof back to the rafters, inspect every timber and replace any that show rot or splitting. New breathable membrane goes down over the whole roof area before battens and tiles are fixed. Flashings around chimneys, party walls and soil pipes are renewed in lead or code-matched materials. We also check and improve ventilation at eaves and ridge level to meet current standards and protect the new roof from the inside.

A replacement gives you a clean slate — no inherited problems, no patches over old patches. It also adds value and is a selling point that surveyors and buyers notice. Trying to extend the life of a failing roof through repeated repairs typically costs more over five years than a single replacement done properly.

We survey the roof before quoting, so the price we give is based on the actual condition we find, not an estimate made from the ground. Replacement work on a typical Diss semi-detached house usually takes four to six working days. We clear all waste from site and leave gutters clean before we leave.

Roof replacements by Diss Roofers carry a ten-year workmanship guarantee. A full roof replacement on a standard semi-detached house in Diss typically costs between £5,500 and £9,000 depending on tile choice and roof configuration.

Questions

What people ask first.

A new pitched roof on a standard three-bedroom detached house in Diss typically costs between £6,000 and £10,000, depending on the tile or slate chosen and the complexity of the roof shape. Hipped roofs and those with multiple valleys or dormers cost more than a simple gable pitch. We provide a fixed written quote before work begins so there are no surprises.
If you're having tiles repaired or replaced more than once every couple of years, or if your roofing felt is more than thirty years old, a full replacement is usually the more economical choice. Signs like sagging roof lines, widespread moss and lichen penetrating the tile surface, or persistent damp patches inside the loft after rain all suggest the roof structure and underlay are failing. We'll give you an honest assessment after a survey.
Replacing a single broken or slipped tile typically costs between £150 and £350 including materials and call-out. Repointing a full run of ridge tiles on a semi-detached house usually falls between £300 and £800. Renewing lead flashings around a chimney stack generally costs £400 to £900 depending on the size of the stack and complexity of the detail. We quote in writing before starting any work.
GRP fibreglass flat roof replacement in Diss typically costs between £70 and £120 per square metre, including stripping the old covering and making good any soft or damaged decking. A standard single-storey rear extension roof of around 20 square metres would therefore cost roughly £1,400 to £2,400. EPDM rubber systems are usually slightly lower in material cost but comparable overall. We provide a fixed price in writing after surveying the roof.
For a standard three-bedroom semi-detached home in Diss, fascia and soffit replacement typically costs between £900 and £2,200. The price depends on the total length of roofline, whether the rafter feet need any remedial work, and the type of material used. We provide a written, itemised quote before any work begins.
Lead flashing replacement on a chimney stack in Diss typically costs between £250 and £600, depending on the number of sides and the amount of lead required. Valley lead replacement on a standard pitched roof is usually between £400 and £900. We'll give you a fixed price after inspecting the work.
A full chimney rebuild in Diss typically costs between £1,500 and £3,500, depending on the height and condition of the stack, the number of flues, and whether new lead flashing and pots are required. Scaffold is usually included in the price. We'll give you a fixed written quote after inspecting from scaffold level.
Chimney take-down and roof make-good in Diss typically costs between £800 and £2,000. The price depends on the height of the stack, the type of roof covering, and whether any internal chimney breast work is involved. Scaffold is included in our price. We'll quote in writing after inspecting the job.
