Is It Time to Replace Your Flat Roof?
Flat roofs fail differently to pitched roofs — these are the signals worth acting on.
Standing water after rain
Water pooling for more than 48 hours points to a fall or drainage problem, not just a membrane issue.
Cracking, blistering or bubbling
Visible surface damage means the membrane's waterproofing is starting to fail.
Leaks at edges or upstands
Most flat roof leaks start at joints and edge details, not the flat surface itself.
Roof is past 15–20 years old
Most flat roofing systems reach the end of their practical life in this window, even felt that looks intact.
Six Systems, Honestly Matched to Your Roof
Every flat roofing material has genuine trade-offs on cost, lifespan and suitability. Your surveyor recommends a system based on your roof — not the highest-margin option.
EPDM (Rubber)
A single-sheet synthetic rubber membrane with almost no seams, giving excellent long-term watertightness. A reliable, low-maintenance all-rounder for extensions, garages and dormers.
GRP (Fibreglass)
A rigid, glass-reinforced resin applied wet and cured into a seamless, glass-hard surface. Fully walkable once cured — a common choice for roof terraces and balconies.
Felt (Built-Up / Torch-On)
Multiple layers of bitumen-based felt bonded together, either torched on or self-adhesive. The most affordable flat roofing system — a practical choice for garages and sheds.
Single Ply (PVC/TPO)
Large, factory-made membrane sheets mechanically fixed or fully bonded to the deck. Lightweight, highly weather-resistant and quick to install on larger roof areas.
Liquid Roofing
A cold-applied liquid coating that cures into a fully seamless, flexible membrane. Ideal for awkward junctions and roof lights, and can often go directly over sound existing felt.
Hot Melt
Hot liquid rubberised bitumen applied at high temperature and reinforced with fleece to form an extremely durable, seamless membrane. Often specified for inverted or green roofs.

Bromley’s property types shape the most common chimney jobs here.
Beckenham & Penge's 1930s Semis
Larger plots across Bromley mean rear extensions and loft conversions are common — usually the most frequent source of flat roofing enquiries here.
Suburban Garage & Outbuilding Roofs
Detached and semi-detached properties across the borough often have separate garage roofs needing their own flat roof system, independent of the main house.
Chislehurst's Conservation Areas
Flat-roofed extensions near Chislehurst's older properties sometimes need a low-profile system that doesn't compete visually with the original roofline.

What Bromley Homeowners Say
Beckenham · Full Flat Roof Replacement
“Full flat roof replacement on our 1960s extension. The team explained why EPDM suited us better than felt before we’d even asked. New roof looks fantastic and the price matched the quote exactly.”
Chislehurst · GRP Roof Terrace
“Wanted a walkable roof terrace and GRP was recommended over cheaper options because we actually needed something durable underfoot. Glad we listened — finish quality is excellent.”
Greenwich · Liquid Roof Repair
“Old felt roof with awkward roof lights we thought would need a full strip-out. Liquid system went straight over the top, done in a day, no leaks since.”

Flat Roofing in Bromley, Answered
It depends on your roof's size, access, budget and how it's used — a walkable terrace needs GRP, an awkward roof with roof lights often suits liquid, a large commercial area usually suits single ply. Your surveyor will recommend a system honestly based on your specific roof, not push the most expensive option.
It varies significantly by system — felt typically lasts 15–20 years, while EPDM, single ply and hot melt can last 30 years or more with proper installation and maintenance.
Sometimes — liquid roofing systems can often be applied directly over sound existing felt, which saves cost and disruption. Your surveyor will confirm whether your existing roof is suitable during the free survey.
Some flat roofs are designed with a slight fall and shouldn't hold water for more than 24–48 hours after rain. Water pooling longer than that usually indicates a drainage or fall problem that's worth having assessed before it causes membrane damage.
Often not, depending on access and roof height — many flat roofs on single-storey extensions can be accessed safely with a tower or ladder access. Your surveyor will confirm what's needed and include it in your fixed price if required.
