Flat Roofing in Newmarket

Flat Roofing for Newmarket Properties

Newmarket has flat roofs on domestic garages, rear extensions and a significant number of commercial and equine buildings. Many domestic flat roofs on the 1960s estates along Exning Road and Studlands Park were originally covered in mineral felt that's now well past its life. We replace these with modern GRP or EPDM systems that handle the chalk downs' temperature extremes — hot summers and freezing winters.

Stable Block and Yard Flat Roofs

Training yard tack rooms, feed stores and stable block lean-tos frequently have flat roofs that need attention. These buildings often have irregular shapes and multiple service penetrations that require careful detailing. We work around yard schedules and use systems that can handle the ammonia-rich air common in stable environments — EPDM is particularly resistant.

Our Process

How We Handle Flat Roof Installation in Newmarket

01

Deck Inspection

We strip the old membrane and inspect every board. In Newmarket, the elevated chalk downs with harder frosts and stronger winds than the Cambridge basin means deck deterioration is possible if the old membrane has been leaking — we check every square inch of Newmarket flat roof replacements.

02

Drainage Design

We calculate the correct fall for your specific roof — minimum 1:40, achieved with tapered insulation boards where the existing deck is flat. For Newmarket properties, proper drainage is critical given the elevated chalk downs with harder frosts and stronger winds than the Cambridge basin.

03

Membrane Installation

EPDM or GRP is installed to manufacturer specification. For Newmarket, we typically recommend the system best suited to each specific application — EPDM for garages, GRP for walkable surfaces.

04

Detailing and Handover

Edge trims, upstand flashings and drainage outlets are finished to a standard that handles Newmarket's conditions. You receive the 10-year guarantee and maintenance guidance specific to your chosen system and Newmarket's climate.

Customer Reviews

What Our Customers Say

★★★★★

"New GRP roof on the extension — old felt was letting water in every time it rained. The new roof is seamless and has a proper drip edge. Should have done it years ago."

Joanne F. · Studlands Park, Newmarket
★★★★★

"EPDM flat roof on the tack room at the yard. They worked around the horses' routine and had it done in a day. Neat job, no mess, and the price was fair."

Marcus P. · Fordham Road, Newmarket
★★★★★

"Garage flat roof replaced with GRP. They found the old boards were rotten underneath the felt and replaced them too. Completely watertight now."

Honest advice

How to Tell You Need Flat Roofing

Flat roofs fail in predictable ways. If your garage, extension or dormer roof shows any of these, it is time to look at repair or replacement.

When it is not the answer: If the deck is sound and the covering is only locally split, a repair or overlay is cheaper than a full replacement — we will tell you honestly which yours needs. Read the full guide.

Access

Access, Scaffolding & Permits in Newmarket

Most flat roofs are low and reached from towers; scaffold is added only for extension roofs at height or with parapets. Scaffold is specified for: first-floor extension roofs, parapet detailing, and any flat roof over a storey up - always itemised in your written quote, never a hidden extra, and we arrange it.

Newmarket's Victorian terraces and estate cottages often have shared access and limited frontage for scaffold. Pavement scaffold and skip permits go through West Suffolk Council; allow a few working days on streets like All Saints Road, the High Street terraces where space is tight.

Guarantee

The Guarantee in Plain Terms

Our flat-roof workmanship is guaranteed for 10 years, on top of the 20–25 year manufacturer material warranties on EPDM and GRP.

If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.

BS 6229, the British Standard for flat roofing, requires a minimum finished fall of 1:40 so water drains within a reasonable time — ponding that lingers beyond 48 hours is the leading cause of premature flat-roof failure.

Yes. We regularly fit and replace flat roofs on stable blocks, tack rooms and yard buildings across Newmarket. We use EPDM or GRP depending on the application and work around your yard schedule.

Most domestic flat roofs are completed in 1–2 days. Stable block roofs depend on size — typically 2–4 days. We confirm timelines before starting.

Signs include: standing water that doesn't drain within 48 hours, bubbling or cracked membrane, soft or spongy areas when walked on, and visible splits at joints or edges. If your felt roof is over 15 years old, it's likely past its useful life.

Why Newmarket Specifically

Why Newmarket Matters for Flat Roofing

Newmarket sits on exposed chalk downs where temperature extremes are more pronounced than in the Cambridge basin — harder frosts in winter accelerate tile deterioration through freeze-thaw cycling. For flat roofing, this means clay plain tiles on the older stock suffer frost lamination 30–40% faster than equivalent tiles in sheltered locations, and lead on outbuildings near stud farms faces theft risk requiring security fixings.

The town's character is shaped by the racing industry — Georgian and Edwardian properties along the High Street sit alongside stud farm outbuildings, stable blocks and training yard buildings that all require specialist roofing.

What This Means for Your Flat Roofing

We schedule equine building work around racing calendars and yard routines, and fit security-fixed lead on exposed outbuildings as standard. Newmarket is 14 miles east from our Cambridge base — close enough for same-day response on urgent work and regular maintenance visits.

Flat Roof Materials for Newmarket

We use two flat roofing systems in Newmarket: EPDM rubber membrane (1.2mm Firestone or ClassicBond) and GRP fibreglass (Scott Bader resin with 450gsm mat). For Newmarket properties facing elevated chalk downs with harder frosts and stronger winds than the Cambridge basin, we recommend the system best suited to each application based on access needs and deck condition.

Deck Standards for Newmarket

The deck beneath the membrane determines how long the roof lasts. We use 18mm WBP plywood for GRP installations — never OSB, which flexes and causes GRP to crack. In Newmarket, we inspect every board and replace any that show softness, delamination or rot before the new membrane goes on. A flat roof is only as good as what is underneath it.

Getting your roof sorted starts with a single phone call. We answer the phone ourselves — no call centres, no automated menus. Tell us what you need, and we will arrange a free site visit at a time that works for you. During the visit, we inspect the roof in person, take photographs of any issues, and discuss your options face to face. You will receive a detailed written quote within 48 hours — itemised, with materials specified by name and a clear timeline for the work.

There is no pressure to proceed and no obligation. If you decide to go ahead, we schedule the work at a time that suits you and confirm everything in writing. Most repairs are completed within two weeks of booking. Larger projects like re-roofs are typically scheduled 3-4 weeks ahead, depending on the time of year.
