📞 Call Now: 01243 278085The cheek flashings, front apron, flat top or pitched dormer covering, and the junction with the main roof all require correctly specified lead work that moves with the building and stays watertight through decades of thermal cycling. When any element fails, water finds its way in at the most complex junction on the roof.
Cheek flashings — the lead strips running down each side of the dormer where it meets the main roof — are the most common dormer failure point. They are subject to both the thermal movement of the dormer structure and differential movement between the dormer and main roof. On properties over 60 years old, original cheek flashings are often at end of life. Full replacement in Code 4 lead with correctly formed and fixed steps gives 50 to 80 years' service.
Flat-topped dormers have two appropriate covering options: lead for conservation area and listed building properties; GRP fibreglass for standard residential outside conservation areas. GRP handles thermal cycling on flat dormers better than felt — its design life of 25 to 40 years compared to felt's 8 to 12 makes GRP the correct specification for any new flat dormer top installation on a standard property. We do not specify felt for flat dormer tops.
Adding or substantially altering a dormer on a property in Chichester's conservation areas typically requires consent. Even replacing like-for-like on a listed building requires Listed Building Consent where the work goes beyond routine maintenance. Repair and replacement in appropriate materials — lead, clay tile, natural slate — is generally permitted. We advise on the consent position before any work starts on designated properties.

Dormers have more flashing junctions than any other roof feature, so they leak first — at the cheeks, the flat top, or where they meet the main slope.

Dormer leaks are among the most complex to diagnose accurately because water can enter at one junction and appear internally at a completely different location after tracking along timbers or running behind linings. We inspect from close range — scaffold or cherry picker — covering every element: cheek flashings on both sides, front apron, back gutter, any flat dormer top covering, and the junction between the dormer and the main roof covering. In Westhampnett Chichester, where period flint cottages and modern Goodwood-edge residential, the typical failure modes depend on the property age — original Victorian leadwork reaching end of service life on period properties; inadequate original flashing specification on post-war additions.
For standard residential properties in Westhampnett Chichester outside conservation areas, GRP fibreglass is our flat dormer top recommendation. The seamless GRP surface eliminates the joint-and-seam failure mode that makes felt flat dormer tops short-lived, and its 25 to 40 year design life means one installation rather than a repeated 8 to 12 year replacement cycle. For listed buildings and conservation area properties in Westhampnett Chichester, lead is the correct specification — it is appropriate to the building character, long-lasting when correctly installed, and the only material that conservation officers will accept on heritage properties. We do not offer felt for any new flat dormer top installation.
Cheek flashing replacement on a standard dormer in Westhampnett Chichester costs £400 to £900 per side. A full leadwork package covering both cheeks, front apron and back gutter runs £1,200 to £2,000. GRP flat dormer top replacement is £500 to £1,200 depending on dormer size. All costs include scaffold where required. Written quotes after a free survey with no obligation.
