Flat Roofing Repairs & Replacement Burgess Hill
If your flat roof is showing signs of damage, the right solution will depend on the overall condition of the roof. In many cases, a targeted repair can resolve isolated problems and extend the life of the existing roof.
Don't let a small leak become a big bill
Many of the flat roofs we see around Burgess Hill sit on extensions, garages, and dormers added to older properties, exactly the kind of roof that gets overlooked until a stain appears on the ceiling below. We work with homeowners across the town, including Hassocks, Wivelsfield, and the Ditchling Common side of Burgess Hill, catching problems while they’re still cheap to fix rather than after they’ve spread to the timber deck underneath.
Common flat roofing problems we deal with include:
- Leaking flat roofs causing damp patches, water ingress, and internal staining
- Blistering, cracking, or lifting membranes that allow water to penetrate the roof surface
- Pooling water caused by poor drainage or ageing roofing materials
- Cold rooms and heat loss from older flat roof construction and worn insulation
- Loose ridge, hip, or verge areas that allow wind-driven rain to enter the property
- Recurring mortar failures on ridge or verge lines that repeatedly require repair

Frequently asked questions
How long should a flat roof last?
How long a flat roof lasts comes down to the materials used and, just as importantly, how well it was fitted in the first place. A well-installed system, properly maintained, should give you decades of reliable service. Around Burgess Hill, flat roofs tend to crop up on rear extensions, garage conversions, and dormer loft additions, common upgrades on the town’s mix of interwar and post-war housing stock. Being inland and close to the South Downs, Burgess Hill roofs don’t face the same salt-air corrosion as coastal towns, but the tree cover around areas like Ditchling Common and the town’s slightly elevated position mean roofs collect more leaf litter and take a fair bit of exposure to driving rain rolling off the Downs, so keeping gutters and outlets clear matters more here than it might elsewhere.
Is torch-on felt or GRP better?
Both are proven systems, and the right choice usually comes down to your roof’s shape, how it’s used, and your budget. Torch-on felt is a cost-effective option that works well on straightforward flat and low-pitch roofs, applied in heat-bonded layers to create a watertight seal. GRP fibreglass costs a little more but forms a single, joint-free surface that’s easier to keep watertight over the long run, particularly on roofs with lots of corners, upstands, or pipework to detail around. If your roof gets heavy foot traffic, such as a roof terrace or a walkway, GRP’s toughness usually makes it the better fit. We’ll advise on the best system for your specific roof during the survey rather than pushing one option across the board.
What is a warm roof and do I need one?
A warm roof is a construction method where insulation sits above the roof deck and below the waterproof membrane, rather than tucked inside the roof void underneath. This keeps the structural timber warmer and drier, which cuts down on condensation and the risk of damp or rot forming inside the roof build-up over time. It’s a particularly worthwhile upgrade if you’re re-roofing an older extension or garage conversion in Burgess Hill built to older insulation standards, or if you’ve noticed cold spots or condensation in a room below a flat roof. Not every roof needs it, so we’ll only recommend a warm roof upgrade where it’ll actually make a meaningful difference to comfort and roof longevity.
Can you repair a flat roof instead of replacing it?
In many cases, yes. If the underlying roof deck is sound and the problem is isolated, such as a split seam, a failed detail around an outlet, or localised blistering, a targeted repair can resolve the issue and add years of life to the existing roof for a fraction of the cost of a full replacement. Where the roof covering has failed more widely, the insulation is saturated, or the deck itself has started to deteriorate, replacement usually becomes the more sensible long-term option. We’ll always give you a straight answer on which category your roof falls into during the survey, along with the reasoning behind it, rather than defaulting to the more expensive option.
Do you work on garages, dormers, and balconies?
Yes. Alongside main roof areas, we regularly work on smaller flat roof structures including garages, dormer windows, balconies, canopies, and porch roofs, all common features on the extensions and outbuildings we see across Burgess Hill and the surrounding Mid Sussex villages. These smaller roofs are just as prone to leaks and membrane failure as larger ones, and often get overlooked during general property maintenance, so it’s worth having them checked as part of any wider roofing survey.
Can I submit a question before booking?
Absolutely. If you have a question about a flat roof problem or want advice before arranging an inspection, you can get in touch and we’ll be happy to help. Whether you’re based in central Worthing or surrounding areas such as Goring-by-Sea or Tarring, we’re always happy to provide guidance.
