Flat Roof Replacement

If your existing flat roof is worn, sagging, blistering or repeatedly leaking, replacement is often the safest option. We remove the old covering, inspect the deck underneath and install a new flat roofing system that fixes the root cause, not just the visible damage.

About Our Flat Roofing Services

Flat roofs are common in Lightwater, particularly on single-storey extensions, garages and post-war housing. The surrounding woodland means leaves, pine needles and moss are constant issues if drainage and detailing are poor. Our approach focuses on correct falls, durable materials and clean finishes, so your flat roof performs properly year after year without constant maintenance headaches.

Flat Roofing Systems We Install

We recommend flat roofing systems based on roof size, access, budget and how the space is used, not a one-size-fits-all solution.

EPDM Rubber Roofing

EPDM rubber roofing is a popular choice in Lightwater due to its flexibility, resistance to cracking and low maintenance needs. It handles temperature changes well and is ideal for garages and extensions where long lifespan matters.

GRP Fibreglass Roofing

GRP fibreglass roofing creates a seamless, rigid surface that is fully waterproof and easy to maintain. It works particularly well on smaller flat roofs and areas where a clean, modern finish is preferred.

Torch-On Felt Roofing

Modern torch-on felt systems offer a cost-effective and reliable flat roofing solution. When installed correctly, they provide strong waterproof protection and are a sensible option for many domestic flat roofs in Lightwater.

Liquid Roofing Systems

Liquid roofing systems are useful for roofs with awkward shapes, multiple penetrations or refurbishment projects. The coating forms a continuous waterproof layer that bonds to the surface and seals problem areas effectively.

Why Homeowners in Lightwater Choose Us?

Homeowners want straight answers, not sales talk. We inspect the roof properly, explain what’s wrong in plain terms, and recommend the right fix for the roof and the budget. We turn up when we say we will, keep the site tidy, and leave you with a roof you don’t have to worry about.
