New Roofs & Re-Roofing in Swindon, Wiltshire & Bristol

Common signs that a roof is nearing the end of its life include persistent leaks that return after repair, multiple missing or cracked tiles, sagging ridgelines, daylight visible through the roof boards, and deteriorating felt underneath. If your roof is over 40–50 years old and has not been re-roofed in that time, it is worth having it inspected. We offer free roof inspections across Swindon, Wiltshire, Bath and Bristol — call 01793 230 678 to book one.

For a typical three-bedroom semi-detached property, a full strip and re-roof usually takes three to five working days, weather permitting. Smaller terraced houses can be completed in two to three days, while larger detached properties with complex geometry may take up to two weeks. We provide a clear timeline before work starts and we leave the roof safe and weathertight at the end of each working day.

The cost depends on the size of the property, the roof type and the materials used. As a general guide, a full re-roof on a three-bedroom semi-detached in Swindon typically ranges from £4,500 to £8,000 including scaffold and waste removal. A smaller terraced property may be lower; a larger detached with complex roof geometry will be higher. We provide a free, fixed-price written quote after visiting the property — no commitment to proceed.

We supply and fit a full range of roofing materials including concrete tiles (Marley, Redland), clay tiles, natural Welsh slate, reclaimed slate for period properties, and flat roofing systems including GRP fibreglass and EPDM rubber. The right material depends on your property type, your local planning requirements (particularly for conservation areas) and your budget. We talk through the options during the quote visit so you can make an informed choice.

A full re-roof gives you the opportunity to upgrade the insulation and ventilation at the same time. Modern breathable roofing membrane replaces the old bituminous felt found on most pre-2000 roofs, and additional insulation can be added at rafter level during the strip. These upgrades can reduce heat loss through the roof and lower your energy bills — particularly on older properties where the original felt and insulation are no longer performing as they should.

You do not need to be at home for the full duration of the work. It helps to be available on the first morning so we can confirm access, scaffold positioning and any last details. After that, our team works independently and we will contact you by phone if anything comes up. We keep you updated on progress throughout and let you know when we are finished each day.

Yes — all new roofs installed by GWR Roofing Ltd carry our company guarantee covering workmanship. In addition, manufacturer warranties on tiles, slates and other materials are passed on to you where applicable. We are also fully insured for public liability and employer's liability and can provide documentation before work starts.

Yes. For re-roofing jobs where the existing appearance needs to be maintained — particularly on period properties, in conservation areas, or on semi-detached houses where one side has already been done — we source matching tiles or slates to ensure a consistent finish. For natural slate roofs we can source reclaimed Welsh slate or new equivalents that closely match the original in colour, size and texture.

It depends on the condition. If the felt, battens and structure underneath are still sound and the issue is limited to a specific area — such as one slope or a section around the chimney — a partial re-roof may be sufficient. However, if the underlying felt has perished across the whole roof and the battens are deteriorating, a full strip and re-roof is usually the more cost-effective option in the long run. We will assess the roof and give you an honest recommendation either way.
