Roofing and spray foam removal in Crawley.
Updated
We are roofers in Crawley, covering RH10 and RH11. Our most recent job here was spray foam removal and a new roof covering in RH11. Every job starts with a call back, then a free drone or loft survey if needed, so you see the problem before we quote.

Open-cell foam out, and the roof rebuilt behind it.
The house is a detached home in RH11 with a front gable and two valleys where the gable meets the main roof. Open-cell spray foam had been sprayed onto the underside of the roof, over the rafters and the felt.
Taking the foam off showed what it had been hiding. The felt behind it was damaged and some tiles had cracked, so a patch repair would not have lasted. The roof got a new breathable membrane and battens throughout, with the original tiles cleaned and reused wherever they were sound.
What we did
- Scaffolding up on the main working sides of the house.
- Tiles lifted, cleaned and set aside for reuse.
- Open-cell foam taken off the rafters, bagged and removed from site.
- Rafters inspected, cleaned and prepared.
- Old felt and battens stripped, then a new breathable membrane and treated battens fitted.
- Both valleys replaced with new GRP valleys.
- Original tiles relaid and cut in at the valleys, with damaged ones replaced.
- New dry ridge fitted, and 300 mm of mineral wool laid on the loft floor.
The roof was finished and signed off on 26 September 2026. The loft is now insulated at floor level, so the roof space can breathe the way it was built to. We will go back to inspect it within a year.

The removal of badly installed foam insulation revealed damage that could only be properly fixed by replacement of the membrane and cracked tiles etc. Archie and his crew were quick, professional and responded well to all my questions and suggestions. Possibly not the cheapest but a job well done. Thank You John
Roofers in Crawley: what we find on local roofs.
Crawley was designated a New Town in 1947 and grew one neighbourhood at a time, so most roofs here date from the 1950s onwards. RH11 covers Ifield, Langley Green, Gossops Green, Bewbush, Broadfield and Southgate. RH10 covers Three Bridges, Pound Hill, Furnace Green, Tilgate and Maidenbower.
A lot of those homes are now on their first roof covering. Concrete tiles usually outlast the felt underneath them, so a roof can look fine from the street while the underlay has turned brittle. A drone roof survey shows the slopes, valleys and ridge close up without anyone walking on them.
Spray foam is the other thing Crawley homeowners ask us about. It was fitted in many homes as a quick insulation upgrade, often straight onto the felt, as it was on the RH11 job above. If you have it, start with a spray foam inspection: we tell you what type it is, what it is doing to the timbers and whether it needs to come out.
Valleys are worth checking too. Where a gable, dormer or extension meets the main roof, the valley carries a lot of water, and old lead or mortar valleys often fail first. On the RH11 house we fitted GRP valleys, which are preformed glass-fibre troughs that do not rely on mortar bedding.
Crawley is in our home patch, and the surveys are free here as they are everywhere we work. We also handle roof repairs for leaks, slipped tiles and storm damage, and we clear and camera-survey drains across both postcodes.
Crawley questions.
Anything else, just call. You'll speak to someone who knows roofs.
Call us07888 868356Do you cover all of Crawley?
Yes. Crawley is in our home patch, across both RH10 and RH11, from Ifield and Bewbush in the west to Pound Hill and Maidenbower in the east. We also work in the villages around the town. Surveys are free, and you keep the photos and findings whether or not you book any work.
Do I need a new roof if I have spray foam?
Not always. Many lofts only need the foam taken off and the timbers checked. On the RH11 job, the felt behind the foam was damaged and some tiles had cracked, so the roof covering was renewed. We explain before work starts what we might find behind the foam, and show you photos of anything that needs more work.
What insulation goes back after spray foam removal?
Usually mineral wool laid between and over the ceiling joists on the loft floor, which leaves the roof space ventilated as it was designed to be. On the RH11 house we laid 300 mm of mineral wool. If you use the loft as a room, the insulation has to go in the roof slope instead, and we explain the options.
Will you need scaffolding?
For a re-roof, or foam removal with roof repairs, yes. Scaffolding goes up on the sides we are working on and is included in the written quote. For a survey, no: the drone photographs the roof from above and nobody needs to climb on it. Small repairs can sometimes be done from a tower or ladder.
