East Grinstead roofs, old and new
The High Street is the oldest part of East Grinstead, lined with timber-framed buildings that go back to the medieval town, and Sackville College stands in local sandstone at its eastern end. Roofs here are steep, heavy and uneven, with handmade clay tiles, some Horsham stone and oak timbers that have moved over the centuries. Repairs need a light hand: rehang, reuse and match, rather than strip and start again. For anything listed or in the old town centre, check with the council before work starts.
East Grinstead sits high on a ridge above the Weald with Ashdown Forest to the south, so it catches more wind and frost than the towns down on the coast. Victorian and Edwardian villas off London Road and Lewes Road wear tile-hung gables and clay roofs, while Imberhorne, Ashplats and Sunnyside add post-war and later estates under concrete tiles. Frost cracks mortar on ridges and chimneys, and leaves from the forest edge fill gutters every autumn.

What wears roofs down in East Grinstead
Height, frost and very old buildings set the pattern here.
Uneven roofs on timber frames
Old oak frames move, so High Street roofs dip and twist. We rehang handmade tiles to follow the line of the roof, and pack or replace battens so nothing rocks loose.
Frost-cracked chimney pointing
Stacks on high ground take hard frosts, and the mortar joints open up and fall out. We rake out and repoint, rebed the pots in fresh flaunching and renew lead flashing where it has lifted.
Estate roofs reaching their age
Post-war roofs across Imberhorne and Sunnyside have sound concrete tiles over felt and battens that have given up. We strip them, fit breathable membrane and new battens, and relay the good tiles.
Downpipes choked by forest leaves
Leaves blown off the forest edge block hoppers and downpipes until gutters overflow and soak the walls. We clear, repair and reseal the whole system, from gutter to drain.

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.
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.
Absolute class! Came out on the day to replace a broken roof tile at a great price. Would recommend to everyone. Cheers boys!! 👊

Roofing questions from East Grinstead
How do you repair the roof of a timber-framed house on East Grinstead High Street?
Carefully, and with traditional materials. We rehang or replace handmade clay tiles to follow the natural line of the old frame, bed ridges in lime mortar, and use lead rather than modern trims at abutments. The owner or their managing agent should check with the council first on any listed building, and we provide photos and a clear method to help.
Why does frost do so much damage to roofs in East Grinstead?
Height is the main reason. The town sits on high ground, so it sees harder frosts than the coast. Water trapped in mortar and older clay tiles freezes, expands and breaks them apart from the inside. We replace spalled tiles, repoint stacks and rebed ridges in a mix that stands up to the freeze and thaw.
Do you cover Forest Row and Ashurst Wood from East Grinstead?
Yes. We cover East Grinstead and nearby Sussex villages, including Forest Row and Ashurst Wood. Both sit on the edge of Ashdown Forest, where shade and fallen leaves are hard on roofs and gutters, so we include a gutter check with every roof survey we do there. The quote is free across our Sussex service area.
Can Sure Seal replace a flat roof on an East Grinstead extension?
We can, in whichever material fits the extension. We strip the old covering, check and replace soft decking, and lay GRP fibreglass, EPDM rubber, torch-on felt or single ply to suit your roof and budget. Upstands, trims and outlets are all renewed so water leaves the roof properly. Every flat roof contract carries a 14-day cooling-off period, so you can change your mind after signing.
