THE DETAIL
Flat Roofing Explained
SYSTEMS
The Right System for You
From seamless GRP fibreglass to EPDM rubber and high-performance torch-on felt — we assess your structure, span and budget and recommend the best fit.
WHY THEY FAIL
No More Ponding or Leaks
Old flat roofs failed at the seams and falls. We get the upstands, trims and drainage right — the make-or-break details where leaks usually start.
RE-COVER
Repair or Replace?
If the deck is sound we can often re-cover rather than fully replace, saving you money. We’ll inspect honestly and advise the most cost-effective route.
PRICING
Affordable & Fully Insured
Clear, honest pricing and a written workmanship guarantee on every flat roof — we get it right so you’re not calling us back.
LIFESPANS
How Long Will It Last?
A quality flat roof now lasts decades, not years: modern felt 15–20 years, EPDM rubber 25+ years and GRP fibreglass 25–30 years — we’ll match the system to how long you need it to perform.
FLAT ROOF SYSTEMS
Modern Flat Roofing That Actually Lasts
Forget the leaky flat roofs of the past — today’s systems are built to perform.
Perfect Falls
We design correct falls into every flat roof so water drains away cleanly with no ponding.
Watertight Detailing
Upstands, trims and edges are the make-or-break points — and exactly where we excel.
Multiple Systems
GRP fibreglass, EPDM rubber and torch-on felt — we fit the right system for your roof.
AFFORDABLE ROOFING SOLUTIONS
Flat Roofing That Suits Your Property & Budget
Whether it’s a garage, extension or dormer, we’ll match the right flat roof system to your needs.
Garages & Outbuildings
Cost-effective, durable coverings that keep garages, sheds and storage spaces dry for years. We match the system to how the building is used and how long you need it to last, so you never pay for more than the job genuinely requires.
Extensions & Dormers
Premium seamless finishes that complement your living space and lift the look of the whole property. On visible flat roofs we take extra care with the detailing, giving you a clean, modern appearance that performs as well as it looks for decades.
Re-Cover or Replace
We assess the deck honestly and only replace what genuinely needs replacing. If the existing structure is sound, a re-cover can save you a significant amount without cutting any corners — and we’ll always tell you straight which option makes the most sense.
Insulation Upgrades
Improve warmth and cut condensation while the roof is open and accessible. Adding or upgrading insulation at this stage is far cheaper than doing it later, helping reduce your heating bills and keeping the rooms below comfortable all year round.
Fully Guaranteed
Every flat roof is covered by our own written workmanship guarantee and full public liability insurance. Many systems also carry a manufacturer’s material warranty on top, so you’re protected on both the fitting and the materials for genuine peace of mind.
Clear Written Quotes
Transparent, affordable pricing with no surprises along the way. Every quote is itemised in plain English so you can see exactly what you’re paying for, and the figure we agree at the start is the figure you pay at the end — no hidden extras.

Test & Guarantee
We check for watertightness, then hand over your written guarantee.
