Roofing in an old county town
Lewes is built on chalk above the River Ouse, with centuries of building since the castle went up. Down the High Street, through the Cliffe and into Southover you pass timber-framed houses behind Georgian fronts, walls of knapped flint, tile-hanging, and the mathematical tiles Lewes is known for, laid to look like brickwork. The roofs above them carry handmade clay tiles and Welsh slate, often with parapets, box gutters and lead-lined valleys tucked out of sight. Many are listed, so check with the council before anything on the roof changes.
The narrow twittens between the streets make access tight, and on the steep lanes off School Hill scaffolding takes thought. Wallands has larger Victorian villas under slate, while the Nevill, Landport and Malling estates bring interwar and post-war semis under concrete and clay tiles, many with flat-roofed garages and extensions. Damp air off the river and the Brooks keeps moss and lichen growing on north-facing slopes, and we clear it as part of any repair so it stops creeping back into the gutters.

Where Lewes roofs need care
Old materials and tight streets make Lewes roofs a job for people who take their time.
Clay tiles on crooked old roofs
Timber-framed houses behind Georgian fronts have roofs that have settled out of true. We rehang and replace handmade tiles to suit the roof's shape rather than forcing it straight.
Flint and brick chimney stacks
Tall stacks built in brick with flint panels lose mortar to wind and frost. We repoint in a mortar that suits the old work, rebed the pots and dress new lead flashing.
Flat roofs on post-war estates
Garages and extensions on the Nevill and Landport estates were finished in felt that now splits and ponds. We replace them in GRP fibreglass, EPDM rubber or torch-on felt.
Slate on Wallands villas
Victorian slate roofs lose slates to rusted nails and brittle felt. We refix slipped slates, replace broken ones with matching natural slate, and renew the ridge and hip mortar.

Great service for flat & tiled roof repair. Professional and knowledgeable advice on works required. Good management which gave quick response and completion of works required.
Absolute class! Came out on the day to replace a broken roof tile at a great price. Would recommend to everyone. Cheers boys!! 👊
We had an issue with a leak coming from our chimney and on getting up there realised our flat roof had been installed poorly. Brendan was so professional throughout, talking us through everything and not pressuring us to make quick decisions regarding the repair. His team were very efficient and got the job done in 2 days. Brendan kept me updated throughout the job, sending photos of the work. His team left the place spotless, even washing down the roof on completion. Having had a few quotes from some rather suspect companies, these guys are so genuine and clearly take pride in doing the job well. Would recommend and call again if needed.

Roofing questions from Lewes
Do I need the council's permission to repair the roof on a listed house in Lewes?
Check with the council before any work starts, because they decide what needs consent on a listed building. Like-for-like repair is the heart of good work on old roofs: reusing sound tiles, matching replacements and dressing lead the traditional way. We give you drone photos and a written description of the planned work to take to them.
Can you get ladders and scaffolding into the Lewes twittens?
We can, once we have worked out the access. The twittens are narrow and some are stepped, so we choose tower scaffolds, roof ladders or a scaffold from the street side depending on the house. The free drone survey shows us what access the job needs before anyone arrives, and it is all priced into your quote.
Why does wind hit roofs so hard in Lewes?
The town sits in the gap the Ouse cuts through the South Downs, and wind channels along the valley. Ridge tiles, verges and tall chimney stacks catch it first, and loose mortar there gives way in a gale. We rebed or mechanically fix ridges and verges and check every stack on a survey.
Is Ringmer or Newhaven too far out from Lewes for Sure Seal?
Neither is. We cover Ringmer, Barcombe, Kingston, Newhaven and Peacehaven, and up the A26 towards Uckfield. There is no call-out charge anywhere we work, so a village address costs you nothing extra to have surveyed. Every quote includes the free drone survey.
