About This Service
Reliable Flat Roof Repairs and Installations in Surbiton
Flat-roofed extensions and garages are one of the most common features of homes across Surbiton and KT6. They are also one of the most common sources of calls to a roofer. Traditional felt flat roofs installed 10 to 20 years ago are now reaching the end of their lifespan, and many Surbiton homeowners are finding the same leaks returning year after year despite repeated patch repairs.
Maple Roofing is Surbiton’s local flat roofing specialist, with over 30 years of experience installing and repairing flat roof systems across KT6 and Kingston. We work with GRP fibreglass, EPDM rubber, liquid plastic and traditional felt, giving you a genuine choice of system to match your budget and your building. Here is what we offer.
Maple Roofing has been the trusted local Velux installer across KT6 for over 30 years. We supply and fit every Velux model, including pitched roof windows, electric INTEGRA units and centre-pivot glazing, with full flashing, insulation and weatherproofing included as standard. Here is what we offer:
FLAT ROOF SYSTEMS WE INSTALL
Flat Roofing Options Available in Surbiton
GRP Fibreglass Roofing — Recommended for Most Surbiton Extensions
GRP fibreglass is the most popular flat roofing upgrade for Surbiton homeowners replacing old felt roofs. It is laid as a seamless, rigid surface with no joints or seams to fail. A correctly installed GRP flat roof in Surbiton will last 25 years or more and comes with a manufacturer-backed guarantee. It handles foot traffic well, is fully weatherproof and requires almost no maintenance. We install GRP on extensions, garage roofs and dormer windows across KT6.
EPDM Rubber Roofing — Best for Larger Flat Roof Areas
EPDM rubber is a single-ply membrane system with an exceptional lifespan of up to 50 years. It is flexible, UV resistant and performs well on larger flat roof areas where a rigid system would be impractical. EPDM is increasingly popular across Surbiton for extensions and outbuildings because of its long guarantee and very low maintenance requirements. It is laid in large sheets, meaning fewer joins and fewer potential leak points across the roof surface.
Liquid Plastic and Liquid Waterproofing — Ideal for Complex Shapes
Liquid waterproofing systems are applied cold, directly to the existing surface, creating a seamless, fully bonded membrane. They are the best option for flat roofs with complex details, outlets, upstands or awkward junctions that are difficult to cover with sheet systems. Liquid plastic is also widely used for refurbishing existing flat roofs across Surbiton without full strip and relay, reducing cost and disruption on the right jobs.
Traditional Felt Flat Roofing — Most Affordable Option
Torch-on felt remains the most cost-effective flat roofing option for garages and outbuildings across Surbiton and KT6 where longevity is less critical. A quality three-layer torch-on felt system has a lifespan of 10 to 15 years. We use high-specification mineral felt with proper drip edge detailing to maximise performance. If you are on a tight budget or replacing a low-priority outbuilding roof, felt is a practical and proven choice.
Roof Insulation Upgrades — Building Regulations Compliance
When replacing a flat roof on a Surbiton property, current Building Regulations require insulation to be upgraded to meet minimum thermal performance standards. Maple Roofing installs insulation boards as part of all flat roof replacement projects, ensuring your new roof is both watertight and compliant. A properly insulated flat roof also reduces heat loss from the room below, cutting energy bills in your Surbiton home.
FLAT ROOF REPAIR VS REPLACEMENT
Should You Repair or Replace Your Flat Roof in Surbiton?
This is the question we get asked most often on flat roofing jobs across Surbiton. The honest answer depends on the age and condition of the existing roof. We will always give you a straight assessment at your free inspection — we do not push replacements when a repair will do the job.
Repair is usually suitable when:
- Small blisters or minor splits on a relatively new flat roof
- A single isolated leak with no wider deterioration
- The roof is under 10 years old and otherwise in good condition
Replacement is the better option when:
- Multiple leaks or pooling water across the roof surface
- The roof is over 15 years old with significant felt deterioration
- Upgrading to GRP or EPDM gives 3 to 5 times longer lifespan than re-felting
If your felt roof is over 15 years old and showing multiple failure points, replacing it with GRP or EPDM is almost always better value in the long run. You will spend less over the next 25 years on a single GRP installation than on repeated felt repairs through Surbiton’s winter weather. Call 07902 470310 to book a free assessment.
