10 Year Insurance-Backed Warranty

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.

Cornerstone Roofing in Haywards Heath

Haywards Heath roofs were not all built in the same decade, and it shows. As roofers in Haywards Heath for 35+ years we work across the Victorian and Edwardian terraces around the station and South Road, the post-war semis, and the newer estates at Bolnore Village, Ashenground and Penland. Those roofs went up in different materials to different standards, so they wear out in different ways.

Most of our work in the town is roof repairs, roof replacement and flat roofing. Which of those a roof actually needs comes down to what it was built with and how much life is left in it, not how old it looks from the pavement. Every project is backed by a 10-year insurance-backed warranty.

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!

Pitched Roof Services in Haywards Heath

Most homes in Haywards Heath sit under a pitched roof, and the local mix is broader than people expect. The older streets carry plain clay tile, natural slate, and the occasional Horsham stone roof; the post-war stock leans on interlocking concrete tile; and the newer estates run almost entirely on modern concrete tile profiles. Our pitched roof team covers pitched repairs, re-cover work, and full re-roof work across all of these stock types.

Cornerstone Roofing provide a wide range of specialised services, from high-quality installations of pitched roofs and flat roofs to expert leadwork, chimney repairs, guttering solutions, and more.

Shingle

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.

Slate Roofing

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 Roofing

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 Roofing

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 Roof Services in Haywards Heath

Flat roofing in Haywards Heath usually sits on rear extensions, garages, porches and the dormer cheeks of chalet bungalows around Walstead, Ashenground and Bolnore, rather than on whole buildings. A good deal of it is original 1970s and 1980s mineral felt that has now outlived its material life, alongside newer flat-roofed extensions and garden rooms on the Bolnore Village and Franklands developments.

Our flat roof team fits EPDM, GRP, felt, single-ply and liquid systems across Haywards Heath, and we match the system to the span, the access, and whether the surface needs to take foot traffic.

Signs a Haywards Heath flat roof needs attention:

  • Water pooling that sits for days after rain instead of draining away
  • Blistering, cracking or splits across an older felt surface
  • Lifting or gaps at the edges, upstands and flashings
  • Damp patches, staining or a musty smell on the ceiling below
  • Moss build-up, grit loss, or a generally tired, weathered finish

If you are seeing any of these, our guide to flat roof repair across Sussex explains what is usually repairable and what points to a full re-cover.

Built-Up Felt Roofing

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 Rubber

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 Roof

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 / Fibreglass

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-Applied Membrane

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

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.

Roof Repairs in Haywards Heath

Common pitched-roof repair situations include slipped tiles, ridge or hip-tile failures, lead flashings around chimneys, and felt extensions that have started taking water. For an active leak we will get a temporary cover up so the inside of the property is protected, then survey for a proper repair on a scheduled visit. We cover roof repair work across Haywards Heath, with every repair backed by our 10-year insurance-backed warranty.

Roof Replacement in Haywards Heath

Most Haywards Heath roof replacements do not start with a decision to replace. They start with a leak, a slipped tile, or another repair on a roof that has already had several, and the question of whether the next repair is worth doing at all. Because the town runs from Victorian and Edwardian terraces through post-war semis to the newer estates, the honest answer changes street by street: the point at which a roof stops being worth patching depends on what it was built with.

What decides it is whether the failure is local or general. A single slipped tile on an otherwise sound roof is a repair. Tiles lifting in several places at once, bedding failing along the whole ridge, and daylight showing through the underlay in the loft are one roof telling you the same thing from three directions, and at that point a new roof is usually better value than the run of repairs that would follow.

Signs a Haywards Heath roof has moved past repairing:

  • Repairs needed in more than one area of the roof over recent winters
  • Underlay that has gone brittle and torn where it laps into the gutter
  • Tiles delaminating or flaking rather than simply slipping
  • Ridge and hip bedding lifting along the length rather than in one spot
  • Staining that comes back in the same ceiling after each repair

Where the roof still has years in it we will quote a roof repair and say so plainly. Where it does not, we survey the whole roof, put the findings in writing, and price the full roof replacement properly rather than starting work and discovering the timbers on the way.
