Reliable, high-quality work before, during, and after the scaffold comes down.
Scaynes Hill is a small, semi-rural village a couple of miles east of Haywards Heath, strung out along the A272 on the edge of the Weald. Its houses are scattered rather than tightly packed, a mix of older farm cottages and later infill, many on open plots that take the full weather coming off the surrounding countryside. That exposure is hard on a roof, and it is the kind of work Cornerstone has handled across Scaynes Hill for 35+ years. Every job carries our 10-year insurance-backed warranty.
Cornerstone covers the full range of roofing across Scaynes Hill: pitched and flat roofs, roof repairs, fascias and soffits, guttering, leadwork and chimney work. The village stock is mostly pitched, with clay tile and natural slate on the older cottages and concrete tile on the newer houses, so a lot of local work is matching repair and re-cover. If you would like a roof looked at, our site visits are free and come without obligation.

Replacement of an old and large Velux plus replacements of a few hanging tiles. Good communication, flexible on the timescale to link in with other contract work. The two man team 'gang' worked hard, very diligent, professional, cleaned up well afterwards and it looks very professional. I did feel the project was over priced but I needed it done, however invoiced as their estimate so it was my call to make.![]()

Cornerstone provided a professional survey of our rather unusual shape garden room roof and came up with a quotation that seemed very reasonable for the work required which included removing 5x polycarbonate sheets on a sloping part of the roof, installing boarding and three layers of felt in their place plus re-felting a triangular flat portion of the roof to make a seamless felted roof. The gang arrived onsite ontime and worked really hard in the extreme heatwave. Plenty of tea and cold drinks supplied! The roof was completed ontime and looks very neat. I was particularly impressed with the 'above and beyond' attitude they applied to the job to make sure that it would provide good drainage in wet weather straight into the gutter. 25 year guarantee too!![]()

I have tried to get a reliable roofing company to replace my house gutters and downpipes for several months. I finally spoke to Cornerstone Roofing a few weeks back. I can honestly say it was the best phone call I have made in several years. From start to finish Cornerstone were superb. Fantastic communication, site inspection, quote and completion of work. I very rarely write reviews because there is little exceptional to write about but Cornerstone deserves every one of the five stars I have given them on this review. They are honest, professional, competitive, give transparent advice and the work carried out was nothing short of perfect. If I ever require roofing work to be done in the future I have only one number to call and will have no hesitation in using Cornerstone as my first point of contact.![]()

Cornerstone roofing removed a skylight, then boarded over the gap, and re boarded and felted our garage roof. I was really impressed with all the guys that did the job, they were efficient and friendly and really clean and tidy. The workmanship was really good. Would definitely recommend them! However, it did take ages to receive a quote and the admin side was not quite as efficient which was a shame but the work and roofers were great so would definitely use again. 5 stars! Thank you!![]()

Great service, very professional from start to finish.
Almost every roof in and around Scaynes Hill is pitched. The older farm cottages and houses tend to carry clay tile, natural slate or hung tile, often on exposed plots that take the full force of the weather coming off the surrounding countryside, while the newer infill runs concrete interlocking tile. Our pitched roofing team specs each roof around its existing covering and its exposure, and where original slate or handmade tile can be reclaimed we re-lay it on new battens with breathable underlay and fresh lead flashings rather than strip it out.
Shingles are an overlapping, single-thickness covering laid in courses across a sound deck. They depend on the underlay, the deck condition, and a ventilated batten cavity behind the visible covering. Get any of those wrong and the lifespan drops sharply.
Natural slate is a generational roof covering. Properly laid on fresh battens, with a breathable underlay and sound lead flashings, a slate roof will outlast most owners. We cover slate repairs, slate replacement, and full re-slate work across Mid Sussex.
Stone is a heavy traditional roof covering. The slates are graded by size and laid in diminishing courses (largest at the eaves, smallest at the ridge), which loads the supporting timbers significantly more than a tiled equivalent. Any stone-roofed enquiry calls for a structural survey of the deck and timbers before a quote.
Tile is the most common pitched covering across Sussex. Clay tile (handmade or machine-made) and concrete tile (interlocking or profile) both feature widely on the local stock. Tile lifespan is generally longer than the underlay beneath it, which means a roof can still look sound from the street while the underlay has reached the end of its life. We cover tile repairs, re-bedding of ridges, tile replacement, and full re-covers across Mid Sussex.
Flat roofing in Scaynes Hill covers a good deal of ground that nobody ever looks at. The village is strung out along the A272 on generous plots, and alongside the houses come stores, workshops, stables, garden rooms and garage blocks. Most of those roofs are flat, and most of them have no finished ceiling underneath them.
That matters more than it sounds. On a house a failing flat roof announces itself early, because a stain spreads across a ceiling and somebody picks up the phone. On an outbuilding there is nothing to stain. Water runs down the inside of the deck, soaks the timbers and whatever is stored below, and the first anyone knows of it is a ruined piece of kit or a roof structure that has already gone soft.
Worth checking on a Scaynes Hill outbuilding roof:
Caught early this is usually a roof repair, because the deck is still sound and only the covering has gone. Left long enough the timbers go with it and it stops being a covering job at all. Our flat roof specialists work in EPDM, GRP, built-up felt, single-ply and liquid systems, and will tell you which of the two you are looking at after a free survey.
Modern reinforced multi-layer torch-on felt is a long way from the single-layer felt that gave the material its older reputation. Properly specified, with metal trims and drips at every edge, it gives a watertight finish well into 20-year territory. Felt remains the most economical like-for-like replacement for an existing felt flat roof.
EPDM is a synthetic rubber membrane sold by the roll and laid as a single sheet across most domestic flat roofs. One sheet means no overlaps and no welded joints to fail later. Lifespan comfortably reaches 25 years and beyond on a properly prepared deck.
Green roofs turn a flat surface into planting, additional thermal insulation, and drainage attenuation. They need a sound waterproof base underneath (typically EPDM or a bituminous build-up), proper drainage outlets, and a structural assessment of the supporting joists or deck because the loaded weight is significantly higher than a standard flat finish.
GRP (glass-reinforced plastic, often called fibreglass roofing) is laid wet over a sound deck and cures into a single seamless skin. It’s strong enough to be walked on and available in a range of finishes. Lifespan typically reaches 25 years and beyond on a properly prepared substrate.
Liquid coatings give a continuous, joint-free skin across complex roof details, including parapet cappings, roof-light or vent penetrations, and abutments where a flat meets a pitched tile. They can also be applied as a recoat over an existing failing membrane that’s otherwise structurally sound, which extends the roof’s life without a full strip-out. Most modern liquid systems are vapour-permeable and UV-stable.
Single-ply membrane comes as factory-made synthetic sheets, fixed mechanically, fully bonded, or held in place by ballast, with joints heat-welded on site. Long sheet widths reduce the number of seams on larger flat areas. Lifespan is comparable to EPDM when properly installed.
The roof repairs we are called to most in Scaynes Hill are slipped or cracked tiles, slate slip, worn lead flashings around chimneys, and ridge or hip tiles loosened by exposure on the more open plots. We survey honestly before quoting, and where the timbers and battens are sound targeted roof repairs are almost always better value than a re-cover. An active leak gets a temporary cover first to protect the inside, then a scheduled return for the proper fix, all under our 10-year insurance-backed warranty.
Alongside main roof work we take care of leadwork (chimney flashings, valleys and parapet details), guttering renewal, fascia and soffit replacement, and chimney repointing or rebuilds. On exposed rural property the guttering and lead take a particular beating, so they are often the first things to need attention. While the scaffold is up we will point out anything else worth doing, because handling it in one visit costs less than returning later.
Scaynes Hill property, particularly the older cottages on exposed rural plots, needs a roofer who will match what is there and build for the weather it takes. As a roofer in Scaynes Hill, Cornerstone brings 35+ years of experience, a UK Roofing Awards 2025 Finalist project nearby in Mid Sussex, and a 10-year insurance-backed warranty on every roof. We survey honestly and quote you straight.
Scaynes Hill is a small, semi-rural village a couple of miles east of Haywards Heath along the A272, set among farmland and woodland on the edge of the Weald. Its housing is spread out and varied, from older farm cottages and detached houses to pockets of more recent building, which means roofs here come in a wide mix of tiles, slates and exposures. The open, rural setting leaves many of them more exposed to wind and weather than roofs in the surrounding towns.
