Lead Is the Premium Choice for Dormers and Bay Tops
Dormers, bay window roofs and small flat roof areas present unique waterproofing challenges. Their complex geometry — multiple angles, tight junctions and vertical-to-horizontal transitions — demands a material that can be formed precisely to shape. Sheet lead has been the material of choice for these details for centuries because it can be dressed around any angle, welded at joints and formed with drips that shed water reliably.
Radiant Roofing covers dormers, bay tops and small flat roofs in sheet lead across Kent, Sussex and Surrey. Whether you need a single dormer cheek recovering or a complete dormer rebuild with lead roof, cheeks and flashings, our skilled lead workers deliver a traditional finish that will protect your property for 50 to 100 years.

Frequently Asked Questions
A lead dormer recovery typically costs between £2,000 and £5,000 for the roof, cheeks and flashings. A smaller bay window top costs £800 to £1,500. The price depends on the area, lead code and complexity of the detailing. We provide a fixed quote after measuring and surveying the dormer.
Sheet lead on a dormer lasts 50 to 100 years when correctly installed. Lead is the most durable material available for small roof coverings — it does not crack, become brittle or degrade in UV light like felt, rubber or fibreglass alternatives.
For dormers and bay tops, lead is the premium choice. It can be formed precisely to the complex shapes involved, welded for invisible joints, and lasts significantly longer than GRP or EPDM. For heritage and period properties, lead is often the only appropriate material. For budget-sensitive projects, we can discuss alternatives.
We cover Kent, East Sussex, West Sussex and Surrey. Our teams regularly carry out lead dormer work in Tunbridge Wells, Crowborough, Sevenoaks, Tonbridge, Uckfield, Haywards Heath, East Grinstead and surrounding areas.
