Every Cornerstone roofing project carries a 10-year insurance-backed warranty, alongside the relevant material guarantee from the manufacturer.
Reliable, high-quality work before, during, and after the scaffold comes down.
Burgess Hill has grown out from a small Mid Sussex village into one of the biggest residential towns in the area, and our roofers in Burgess Hill have worked through most of that expansion. We have covered the older Victorian and Edwardian properties near the station and Junction Road, the post-war and 1970s semis through Worlds End and Royal George Road, and the newer estates north of the town off Maple Drive and Kings Way.
Three jobs make up most of what we do here: roof repairs, roof replacement and flat roofing. Which of those a roof needs depends on the age and construction of the covering, and that is a judgement to make on the roof rather than from the pavement. Cornerstone Roofing has been working on Burgess Hill roofs for 35+ years, and every job carries our 10-year insurance-backed warranty.
We handle pitched and flat roofing, repairs, fascias and soffits, guttering, leadwork and chimneys across Burgess Hill. Most of the housing stock here is concrete interlocking tile (Marley and Redland profiles dominate on the post-war and 1970s estates) which means most of what we’re asked to do is tile replacement, re-pointing of ridges, or full re-covers when the underlay has finally given out. We carry enough of the common profiles to colour-match in stock, and we’ll source matching salvage on the rarer ones.
For larger jobs we’ll come out to survey before quoting, free of charge.

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.
The pitched roofs across Burgess Hill split roughly into three eras. The Victorian and Edwardian terraces near the centre tend to be natural slate or plain clay tile. The post-war and 1970s estates that fill out most of the town are concrete interlocking tile, and most of those roofs are now at or past 50 years (the design life of the underlay rather than the tile). The newer developments north of the town and at Worlds End run modern concrete profile tile.
Our pitched roof team works on all three, matching the spec of the existing roof rather than upselling a replacement that isn’t needed.
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 Burgess Hill is mostly an estate story. The post-war and 1970s estates that fill out much of the town, around Worlds End and Royal George Road, came with flat-roofed garages, porch canopies and single-storey rear extensions, and a good share of those are still wearing their original 70s and 80s mineral felt. That felt has had its day, which is why most of our Burgess Hill flat roof calls are re-covers on garages, porches and extensions rather than whole-building roofs. Our flat roofing team fits EPDM, GRP, felt, single-ply and liquid systems, matching the system to the span, the access and whether the surface has to take foot traffic.
If any of those sound familiar, our guide to common flat roof problems walks through what tends to be a straightforward repair and what is really telling you the whole covering is due for renewal.
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.
Common repair situations across Burgess Hill include slipped concrete interlocking tiles on the post-war estates, ridge tile movement after winter storms, and lead flashings around chimneys and abutments. For an active leak we will get a temporary cover up so the inside of the property is protected, then survey for a proper roof repair on a scheduled visit. A roofer who knows the Burgess Hill stock spots the patterns: on a 1970s estate roof with bedded ridges, the ridge line is usually the next thing to go. Every repair is backed by our 10-year insurance-backed warranty.
Re-roofing in Burgess Hill is largely a story about underlay. The post-war and 1970s estates that make up most of the town went on with bitumen sarking felt, and that felt reaches the end of its working life long before the concrete tiles above it do. The tiles can look perfectly serviceable from the pavement while the layer actually keeping water out of the loft has gone brittle and split at the eaves.
That is why replacement tends to arrive in clusters here. Whole runs of houses were built to the same pattern within a short span, so they reach the same point at the same time, and neighbours often find they are dealing with the same problem in the same winter. A new roof on this stock is usually a strip and re-cover: the tiles come off, the old felt and battens go, a modern breathable membrane and new battens go on, and sound tiles go back where they can.
What we establish before quoting a re-roof in Burgess Hill:
If you are not sure whether your roof has reached that stage, our guide to the signs a pitched roof needs replacing sets out what to look for. When it has, our re-roofing work covers the whole job, from the survey through to the finished roof.
Alongside main roof work we replace fascias, soffits and bargeboards, install and repair guttering, take on lead work (chimney flashings, valleys, dormers), and handle chimney repointing and rebuilds across Burgess Hill. Fascias, gutters, and chimney work share the same scaffold access, which lets multiple jobs run together where the access allows.
There are plenty of roofers in Burgess Hill. Cornerstone has 35+ years of roofing experience across Mid Sussex, and every job is backed by our 10-year insurance-backed warranty alongside the relevant material guarantee from the supplier.
Burgess Hill is one of the larger towns in Mid Sussex, with a population of around 32,000 at the 2021 census. It sits between Haywards Heath and Brighton, served by two railway stations (Burgess Hill and Wivelsfield) and bordered to the south by the South Downs National Park. Most of the town developed in the post-war and later decades, with continued growth through the Northern Arc housing development. Worlds End is the principal conservation area.
