About Our New Roofs Services

Whether you are building a new home, adding an extension or replacing a roof that has reached the end of its life, the quality of the installation sets the standard for decades to come. A new roof is one of the most significant investments you will make in your property — and getting it right first time saves thousands in future repairs, energy costs and maintenance.

Radiant Roofing delivers complete new roof installations for homeowners, builders and developers across the South East. We handle every aspect of the project from initial survey and specification through to final tiling, leadwork and rainwater goods. Our team works with all common roofing materials including clay tiles, concrete tiles, natural slate and flat roof systems, and we are experienced in both traditional and modern building methods.

If you are planning a new build, extension or full re-roof, contact us early in the process. We can advise on material selection, building regulation compliance, ventilation requirements and budget planning. Our surveys are free, our quotations are detailed, and our workmanship is guaranteed.

Frequently Asked Questions

A new roof for a typical three-bedroom semi-detached house generally costs between £5,000 and £12,000 depending on the material, roof complexity and whether any structural work is needed. Natural slate and complex roof designs sit at the higher end of the range. Extension roofs vary widely based on size and specification. We provide detailed, itemised quotations so you can see exactly where your money is going.

Most residential new roofs or full re-roofs take between three and seven working days, weather permitting. A simple extension roof may take just one to two days. Larger or more complex projects — such as those with multiple hips, valleys, dormers or skylights — may take longer. We always provide a realistic timeline before work starts.

In most cases, a like-for-like roof replacement does not require planning permission as it falls under permitted development. However, if you are changing the height, shape or materials of the roof, or if your property is in a conservation area or is listed, you may need approval. We can advise on this during your free survey and help you navigate the process if an application is required.

All new roof installations are covered by our written workmanship guarantee, which typically ranges from 10 to 20 years depending on the project scope. Manufacturer warranties on tiles, slates and membranes apply in addition to our own guarantee. We will explain exactly what is covered before work begins.

We install new roofs across the whole of Kent, Sussex and Surrey, including Tunbridge Wells, Sevenoaks, Tonbridge, Maidstone, Crawley, East Grinstead, Haywards Heath, Reigate and the surrounding areas. We also work with developers on multi-plot sites across the wider South East.

Yes. We carry a wide stock of both new and reclaimed tiles and can source most common types quickly. Where an exact match is difficult to find, we can reposition existing tiles so the best match is in the most visible area, or source reclaimed tiles from specialist salvage suppliers. We will discuss your options during the survey.
