Local Knowledge

Flat Roofing in Steyning

In Steyning, the most common Steyning roofing calls are heritage repairs on the listed High Street stock — slipped peg tiles, failed lime pointing and worn Horsham Stone — alongside standard slipped-tile and flashing repairs on the newer estates. Conservation-area and listed-building consent applies across much of the town centre, so material matching and correct lime mortar are essential rather than optional.

Steyning’s position at the foot of the Downs and beside the Adur valley shapes its roofing challenges. The chalk downland to the south funnels wind across the town, so ridge and verge exposure is higher than in the sheltered Weald. The valley setting keeps humidity up, encouraging moss on north-facing slopes, and the older timber-framed buildings need careful, breathable repair to avoid trapping moisture in historic fabric.

What We Do

Flat Roofing Standards in Steyning

For Steyning flat roofs we recommend GRP fibreglass as standard — a seamless, jointless system with a 25-year guarantee — and use EPDM on larger or more complex roofs. We strip the old covering and inspect every deck board before laying the new membrane, correcting falls with tapered firrings so water drains cleanly rather than ponding. Outlets and wall upstands are formed as a single seamless piece, which is where jointed felt systems most often fail.

All our work follows recognised standards — BS 5534 for slating and tiling, Code 5 lead minimum for valleys and flashings, and lime mortar (NHL 3.5) on pre-1930 masonry. We are NFRC registered with £5 million public liability insurance and give a written 10-year workmanship guarantee on every job.

BS 5534 sets the fixing, underlay and dry-fix requirements every compliant UK roof must meet. — BS 5534 (British Standards Institution)
Local Detail

Steyning Roofs in Practice

The town centre is dominated by timber-framed and Georgian buildings, many listed and roofed in clay peg tile or, on the oldest, heavy Horsham Stone. Around Church Street and Charlton Street, Victorian and Edwardian houses carry clay tile and natural slate. The 20th-century expansion toward the Bramber and Ashurst roads brought 1930s and post-war housing in concrete and modern clay tile. This range demands a roofer who can match reclaimed peg tile and Horsham Stone as readily as they lay modern interlocking tile.

Honest advice

Do You Actually Need Flat Roofing?

Flat roofs fail differently from pitched - and the symptoms usually show inside before the roof looks bad outside.

When it is not the answer: A sound deck with one split or a failed lap can be repaired for a fraction of replacement - and if the roof is under 10 years old, the original installer’s guarantee should be your first call, not us. Read the full guide.

Warm deck vs cold deck — insulation above the deck is the current Building Regulations standard.
The process

How a Steyning Flat Roofing Job Runs

1. Survey

We check the covering, the falls, the edge details and - critically - probe whether the deck beneath is sound or rotten.

2. Written itemised quote

Deck condition assumptions stated plainly; warm-deck insulation specified where the room below is habitable (a Building Regulations requirement).

3. Scheduling

GRP and EPDM need dry conditions to cure and bond - we book against the forecast honestly.

4. Strip & deck works

Old covering off, deck inspected, rot cut out and re-boarded, insulation laid on warm-deck builds.

5. New covering

GRP fibreglass laid wet with trims, or one-piece EPDM membrane - edge details and outlets done properly, because that is where flat roofs actually fail.

6. Sign-off

Falls checked with water where possible, guarantee handed over - 20 years on GRP systems we install.

Timescales

How Long Does It Take?

JobTypical duration
Garage roof (single)1-2 days
Kitchen extension2-3 days
Larger wrap-around extension3-5 days
Dormer top1-2 days
Repair to split or lapHalf day

GRP will not cure below about 5°C or in rain - winter jobs wait for a dry window, and we would rather move a date than trap moisture under a new covering.

Access

Access, Scaffolding & Permits in Steyning

Most domestic flat roofs run from towers and edge protection rather than full scaffold. Scaffold is specified for: first-floor or higher flat roofs, and any job with sustained edge work over a public path - always itemised in your written quote, never a hidden extra, and we arrange it.

Steyning High Street and Church Street are conservation-area streets with listed frontages - scaffold licences carry conditions and we photograph party structures before erecting; modern closes off Shooting Field are simple access. Pavement scaffold and skip permits go through Horsham District Council; allow a few working days on streets like High Street, Church Street where space is tight.

Good to know

What It Is Like While We Work

A day or three of resin smell on GRP jobs - strong but temporary - and the deck strip is the noisy part. Gardens below get sheeted, and we need outside power. You do not need to stay home for external work - we just need power and access agreed in advance.

Curing chemistry rules the diary: we lay in dry weather only, and an unexpected shower means stopping and protecting rather than pressing on. Downs-foot position means real wind exposure on south-westerlies plus damp air off the Adur - both factor into fixings and timings.
