Roofers in Crawley for repairs, flat roofs and new roofs.
A leaking roof, slipped tiles, a tired flat roof or a full replacement all start in the same place: understanding what has actually failed. We provide practical roofing across Crawley with clear advice, a defined scope of work and free estimates.
From one failed detail to a complete roof, the job should start with the right diagnosis.
Roofing problems rarely arrive with a neat label. You may notice a damp patch after wind-driven rain, a tile in the garden, water running behind a gutter, staining around a chimney breast or a flat roof that has started to blister and hold water. The useful question is not simply “what can we patch?” It is “where is the water getting in, why has that part failed, and what is the proportionate way to put it right?”
AP Roofing Sussex works across Crawley on pitched and flat roofs, roof repairs, complete reroofing, chimneys, leadwork, guttering, fascias and soffits. Some roofs need a small local repair. Others have reached the point where repeated patching is costing more than addressing the wider build-up. We explain that difference before work begins.
Our main service area covers Crawley and the surrounding Sussex and Surrey border, including RH10 and RH11. That means we regularly deal with the mix of post-war tiled housing, older properties, garages, extensions, dormers and commercial roof areas found across neighbourhoods such as Three Bridges, Pound Hill, Maidenbower, Ifield, Tilgate, Furnace Green, Southgate, Broadfield and Worth.
Roof repairs, flat roofing, new roofs and the details around them
The roof covering is only one part of keeping a building dry. We also work on the junctions, drainage and roofline details that often cause or contribute to leaks.

Explore serviceLeaks often start at a detail: flashing, valleys, edges, penetrations or drainage.A wet ceiling does not tell you where the roof has failed.
Water can travel along battens, rafters, membranes and masonry before it becomes visible indoors. That is why a repair based only on the position of the stain can miss the source completely.
When we look at a leaking roof we consider the surrounding covering, ridge and hip lines, valleys, flashing, abutments, roof penetrations, chimney details, gutters and the direction weather is likely to have driven the water. On a flat roof we also look for failed laps, splits, defective trims, outlets, ponding and movement in the deck.
Once the likely cause is clear, the scope should be clear too. If a targeted repair is sensible, that is what we quote. If the failure is part of wider deterioration, we explain why a broader repair or replacement may give better value than another short-lived patch.
- Leaking roofs traced from the likely entry point, not just the internal mark.
- Tile and slate repairs with attention to the surrounding fixings and weathering.
- Storm damage made safe and then repaired with a permanent solution.
Flat roofs, tiled roofs, slate roofs and complete replacements
Different roof types fail in different ways. The repair method, materials and detailing need to suit the roof that is actually on the building.
Garages, extensions, dormers and commercial flat roofs
Repairs, replacement coverings, insulation upgrades, outlets, edge trims and advice on suitable systems such as EPDM, GRP and modern felt.
Tiles, slate, ridges, valleys, verges and roof junctions
Local repairs through to complete reroofing, with the underlay, battens, ventilation and weathering details considered as part of the system.
Replacement roofing planned as a complete build-up
When reroofing is the right route, we look beyond the visible covering to the supporting layers, insulation, ventilation, flashings and drainage.
The parts of a roof that need to work together
A roof can look simple from the pavement. Up close, reliable weatherproofing depends on dozens of junctions and details all doing their job.
Cracks, slipping, broken nibs, fixing failure, weathering and local matching.
Loose units, failed mortar or dry-fix components and exposed edges.
Debris, splits, poor detailing and areas where large volumes of water are concentrated.
Flashing, pointing, soakers, step flashing and movement around masonry.
Laps, trims, outlets, drainage falls, local ponding and deck condition.
Blocked or leaking gutters, alignment, fascia condition, soffits and eaves ventilation.
Roofing should feel clear from the first conversation
You do not need to know whether the problem is flashing, underlay, a valley or a failed membrane before you call us.
Tell us what you have noticed
Where the problem appears, when it happens and the property postcode are enough to start. Photos help when you have them.
We inspect the roof and likely water path
The visible defect and the surrounding roof are considered together so the quote addresses the cause rather than only the symptom.
You get a defined scope of work
Repair, maintenance or replacement is explained in plain English, with the work included set out before you decide.
Roofing across RH10, RH11 and surrounding towns
Crawley is our main local focus, with roofing work across neighbourhoods including Three Bridges, Pound Hill, Maidenbower, Ifield, Tilgate, Furnace Green, Southgate, Northgate, West Green, Langley Green, Gossops Green, Broadfield, Bewbush and Worth.
We also cover nearby towns across West Sussex and the Surrey border. Each area page links back to the relevant technical roofing services so you can understand both the local coverage and the work itself.
Useful answers before you book a roofer
These are some of the practical questions that come up before an inspection or quote.
Yes. A single slipped tile, a failed section of flashing, a leaking gutter joint or a local flat-roof defect can be a complete job in its own right. We do not expect every enquiry to become a new roof.
We look at the likely water path rather than assuming the stain indoors is directly below the defect. Tiles or slates, valleys, flashings, roof penetrations, gutters and the surrounding roof condition all matter.
Yes. We work on common flat-roof systems as well as tiled and slate pitched roofs, including garages, extensions, dormers, porches and larger roof areas.
Usually when defects are no longer isolated: widespread covering failure, tired battens or underlay, repeated leaks in different areas, or several major details reaching the end of their life together. We explain the condition before recommending replacement.
We cover RH10 and RH11, including areas such as Three Bridges, Pound Hill, Maidenbower, Ifield, Tilgate, Furnace Green, Southgate, Broadfield, Bewbush, Gossops Green, Langley Green, Worth and surrounding neighbourhoods.
Yes. Roofline, drainage, leadwork and chimney details are often part of the same water-management problem, so we inspect them together where relevant.
