How to Tell It's Replacement, Not Repair
A patch repair can only stretch a roof so far. These are the signals our surveyors look for when deciding whether a repair still makes sense.
Roof is past 20–25 years old
Most pitched and flat systems reach the end of their practical lifespan in this window, even without visible damage.
Repeat leaks in different spots
A leak that keeps reappearing in new locations usually means the underlying structure has failed, not just the surface.
Sagging or uneven roofline
Visible dips or sagging from the ground almost always point to structural timber or decking failure underneath.
Rising energy bills
Failing insulation and ventilation in an ageing roof is one of the most common — and most overlooked — causes of heat loss.
The Right System for Your Property
Your surveyor recommends a system based on your roof’s pitch, structure and budget — never the other way around.
Slate & Tile Roofing
Natural slate, clay and concrete tile systems for traditional and period London properties, matched to conservation requirements where they apply.
EPDM, GRP & Single Ply
Rubber, fibreglass and single-ply membrane systems for extensions, garages and full flat-roof replacements, built to shed water correctly first time.
Warm Roof Construction
Insulation built into the roof structure itself, reducing heat loss and condensation risk versus a standard cold-roof build.
Commercial & Industrial
Larger-scale flat and low-pitch systems for warehouses, retail units and offices, scheduled around your business's operating hours.
From First Call to Signed-Off Roof
Free on-site survey
A surveyor inspects your roof, discusses options honestly, and takes measurements — no obligation, no charge.
Fixed price confirmed
You receive one clear fixed price covering materials, labour, scaffolding and waste removal. Nothing added later.
Roof installed
Your crew completes the install to the agreed programme, keeping the site tidy and your property protected throughout.
Sign-off & guarantee
Final inspection, site clean-up, and your 12-month workmanship guarantee issued before the crew leaves.

Roof Replacement, Answered
Most single-property re-roofs take 3–7 working days depending on size, roof pitch and weather. Your surveyor gives you an exact programme before work starts.
Most like-for-like replacements don't need planning permission. If your property is listed or in a conservation area, or you're changing the roof's height or shape, we'll flag this during your free survey.
Your property is protected with weatherproof sheeting at the end of every working day, so a rain delay never leaves your home exposed.
Yes — scaffolding, skip hire and waste removal are all included in your fixed price quote, not added as extras afterward.
If any fault develops in our workmanship within 12 months of completion, we return and fix it at no charge. This is separate from any manufacturer material warranty registered on your roof.
