Flat roof repairs and replacements in Castleford
Flat roofs are where a lot of Castleford's leaks start. Garages, kitchen extensions, back offshoots and dormers were often finished in felt that has since blistered, cracked and pulled away at the edges. Our flat roof work in Castleford covers repairs to existing roofs and full replacement in EPDM rubber, GRP fibreglass or torch-on felt.
A flat roof is never truly flat. It needs a fall to shed water, sound decking underneath and properly detailed edges and upstands. When any of those is missing, water sits on the surface and finds the weak spots. Fixing the surface without sorting the cause is why some flat roofs leak again a year later.

Flat roofing options in Castleford
EPDM rubber roofs
A single rubber membrane with no seams across the main area, well suited to garages and extensions.
GRP fibreglass
A hard, seamless finish that copes well with foot traffic, good for dormers and balconies.
Torch-on felt
Modern multi-layer felt systems bonded in place, a reliable choice for larger or commercial roofs.
Flat roof repairs
Blisters, splits, failed edges and leaking upstands repaired where the deck is still sound.
Garages, extensions and offshoots across Castleford
On the older terraces, flat roofs usually cover rear offshoots, bathrooms and outriggers that were added over the years. On the post-war estates and newer housing it is more often garages, porches and single-storey extensions. Many of these were done decades ago in basic felt with chipboard decking, and when water gets through, the deck swells and starts to sag.
We work on flat roofs throughout WF10, including Allerton Bywater, Whitwood, Airedale and Glasshoughton, as well as Pontefract. Castleford is covered by our Yorkshire team, who work across Leeds, York, Malton and the surrounding towns. We also handle flat roofs on commercial buildings and rented property.
Choosing the right flat roof material
There is no single best flat roof system. EPDM is quick to fit and flexible, GRP gives a hard and tidy finish, and felt systems are well proven on bigger roofs. The right choice depends on the size of the roof, how it is used, the details around it and your budget.
We inspect the deck as well as the surface, check the fall and the drainage, and then recommend a system. If the boards are rotten, we replace them rather than lay a new membrane over a failing base.
Flat roof questions from Castleford
My garage roof has puddles after rain. Is that a problem?
Small puddles that dry within a day or two are fairly common. Large ponds that sit for days mean the fall is poor or the deck has sagged. Standing water speeds up wear and finds any weakness, so it is worth having it looked at, especially on an older felt roof.
Can a new rubber roof go over the old felt?
Sometimes, but usually we strip it. Laying over an old roof hides any rot or damp in the deck, and trapped moisture can cause problems later. If the old felt and deck are sound and dry, an overlay may be possible. We decide after inspecting.
Is GRP or EPDM better for a dormer?
Both work well. GRP gives a hard, neat finish and is easy to detail around edges and trims, which suits dormers that can be seen from the street. EPDM is flexible and quick to fit. We will recommend one based on the size and shape of your dormer.
Can you repair a flat roof rather than replace it?
Yes, if the problem is local and the deck underneath is dry and solid. Splits, small blisters and failed edge details can often be repaired. If the leaks are widespread or the deck has gone soft, replacement is the more reliable fix.
Can you add insulation when replacing a flat roof?
Yes. Replacement is the right time to improve insulation, which can make a big difference to a cold extension or bedroom over a garage. Adding insulation may affect the roof height and edge details, so we plan it into the job from the start.
Do flat roofs on commercial units need a different approach?
Often. Larger roofs may have more outlets, plant, rooflights and heavier foot traffic. We look at drainage, access and how the building is used before recommending a system, and can work around business hours where possible.
