Our Work

EPDM Rubber — the Low-Maintenance Standard for North East Extensions

EPDM (ethylene propylene diene monomer) rubber is now the industry-standard flat roofing membrane for residential extensions, garage roofs, and bay window tops across the North East. With a 50-year manufacturer guarantee and exceptional resistance to UV degradation and frost cycling, it outperforms traditional felt systems on every measure. VM Roofing installs EPDM as fully adhered single-ply systems with taped seams — no heat welding required on domestic applications.

GRP Fibreglass — Seamless, Rigid, and Maintenance-Free

GRP (glass reinforced polyester) fibreglass is the strongest and most dimensionally stable flat roofing option for walkable surfaces, green roofs, and areas subject to foot traffic. VM Roofing laminates GRP directly over OSB decking on site, creating a fully bonded seamless system with no joints or seams to fail. All GRP installations use ISO-standard resins with a 25-year manufacturer guarantee. The finished surface is UV-stable and can be made non-slip for roof terraces.

Torch-On Felt — the Economical Flat Roof Solution Done Properly

Torch-on felt (modified bitumen) remains a cost-effective and reliable flat roofing system when correctly installed. VM Roofing uses SBS-modified torch-on felt in a minimum two-layer system with fully bonded laps — never single-layer or loose-laid. On North East properties, we specify mineral-faced capsheet as standard for UV resistance and longevity. All torch-on installations come with a 20-year manufacturer product guarantee.

Upstands, Drip Edges and Drainage — Getting the Details Right

The majority of flat roof failures on Newcastle properties begin not at the membrane surface, but at the upstands, drip edges, and drainage points. VM Roofing forms all upstands to a minimum 150mm height above the finished roof surface, installs lead-lined drip edges at all exposed terminations, and specifies correctly-sized rainwater outlets based on calculated roof area and North East rainfall data. Correct drainage specification is the single greatest determinant of flat roof longevity.

Flat roofs cover bay windows, rear extensions, garages, and outbuildings on thousands of Newcastle and Tyneside homes. When the membrane fails, water finds a way in quickly — and the damage to ceilings, walls, and insulation escalates fast. VM Roofing installs EPDM rubber, GRP fibreglass, and torch-on felt flat roofs across the North East, with every system specified correctly for the North East's rainfall intensity and delivered with a written guarantee.

What Are the Flat Roofing Options Available in Newcastle?

EPDM Rubber Flat Roofing

EPDM (ethylene propylene diene monomer) has become the preferred flat roofing membrane for residential applications across the UK since the 2000s, and for good reason. It is a single-ply rubber sheet installed as a fully adhered, seamless system. Unlike felt, it does not blister, crack, or become brittle in cold weather — critical for North East winters where ground frost occurs on 50–60 days per year.

EPDM at a glance:

  • 50-year manufacturer guarantee
  • Fully seamless with taped joints
  • No maintenance required
  • Unaffected by freeze-thaw cycles
  • Ideal for most domestic extensions and garage roofs

GRP Fibreglass Flat Roofing

GRP is laminated in liquid form and cures into a rigid, seamless shell directly bonded to the roof deck. It is the strongest flat roof system available and the correct specification for walkable roof terraces, roof gardens, and any surface subject to regular foot traffic.

GRP at a glance:

  • 25-year manufacturer guarantee
  • Fully seamless — no joints to fail
  • Can be made non-slip for terraces
  • Rigid and dimensionally stable
  • Available in any RAL colour

Torch-On Modified Bitumen Felt

Modern SBS-modified torch-on felt is a significant improvement on the single-layer felt still found on many older Newcastle extensions. Correctly installed as a two-layer system with fully-bonded laps and a mineral-faced capsheet, it provides genuine 15–25 year performance at the most economical price point.

Important: Single-layer felt (commonly used by builders on extensions before 2000) should not be repaired indefinitely. Once it has been patched more than twice or is over 15 years old, full replacement with a modern system is almost always the more cost-effective decision. VM Roofing will advise honestly on the threshold.

How Much Does Flat Roofing Cost in Newcastle?

System Cost per m² Lifespan Guarantee
EPDM Rubber £70–£100 40–50 years 50-year manufacturer
GRP Fibreglass £80–£120 25–30 years 25-year manufacturer
Torch-On Felt (2-layer) £50–£80 15–25 years 20-year manufacturer

All prices include decking preparation, upstand flashings, drainage outlets, and VAT. Scaffold is itemised separately where required.

Common Questions

Your Questions About Flat Roofing Newcastle Answered

Straightforward answers from VM Roofing's experienced team — serving Newcastle, Gateshead, Sunderland and Durham since 1998.

Which flat roofing system is best for a house extension in Newcastle?

For most residential extensions in Newcastle, EPDM rubber is the recommended system — it carries a 50-year manufacturer guarantee, requires no ongoing maintenance, and performs exceptionally in the North East's wet climate. GRP fibreglass is preferred where the roof will carry foot traffic or require a particularly neat visual finish. Torch-on felt is the most economical option and is entirely suitable when correctly installed with a mineral-faced two-layer system.

How long do flat roofs last in the North East?

The lifespan of a flat roof depends heavily on the system and installation quality. A properly installed EPDM rubber system should last 40–50 years with minimal maintenance. GRP fibreglass lasts 25–30 years before surface treatment may be required. Modern torch-on felt in a two-layer system typically lasts 15–25 years. Single-layer felt, which is still common on older Newcastle extensions, typically fails within 10–15 years and should be replaced rather than repeatedly repaired.

Why is my flat roof leaking on my Newcastle extension?

The most common causes of flat roof leaks on Newcastle extensions are: failed upstand flashings where the roof meets the house wall, blocked or undersized drainage outlets causing ponding, cracked or blistered felt on single-layer systems, and poorly sealed penetrations (soil pipes, rooflights). VM Roofing identifies the precise cause of failure before recommending a repair or replacement — we never apply surface patches without investigating the underlying cause.

Can you add insulation when re-doing my flat roof in Newcastle?

Yes. Flat roof replacement is the most cost-effective point at which to upgrade insulation and meet current Building Regulations Part L requirements. VM Roofing installs warm-deck flat roof constructions using PIR (polyisocyanurate) insulation boards between the structural deck and membrane. This eliminates condensation risk and can reduce heating bills measurably on poorly-insulated Newcastle extensions. We can advise on required insulation thickness for your specific property.

How much does a flat roof replacement cost in Newcastle?

A flat roof replacement on a typical rear extension or garage in Newcastle costs between £800 and £3,500 depending on system specification, roof area, and access requirements. EPDM rubber typically costs £70–£100 per m², GRP fibreglass £80–£120 per m², and torch-on felt £50–£80 per m², including decking preparation and all upstand work. VM Roofing provides a detailed written quotation following a free on-site survey.

Do you repair flat roofs as well as replace them?

Yes. Minor flat roof repairs — patching small splits or blisters, re-sealing upstands, or replacing isolated drainage outlets — are carried out on existing felt, EPDM, and GRP systems. However, if a roof is more than 15 years old or has widespread cracking, blistering, or ponding, VM Roofing will always advise honestly when full replacement represents better long-term value than continued patch repair.
