Flat Roofing

Modern flat roofing systems that actually stay watertight.

Overview

Flat Roofing You Can Depend On

Flat roofs have a reputation for problems, but in reality, most failures come down to poor installation rather than the flat roof concept itself. Advanced Roofers Ltd installs modern, high-performance flat roofing systems — including single-ply EPDM rubber, GRP fibreglass and reinforced felt — engineered to shed water effectively and resist UV degradation for decades.

We regularly install flat roofs on house extensions, garages, dormer windows, garden rooms and commercial units. Every installation begins with correct falls to ensure water is directed to outlets rather than pooling on the surface, along with appropriate insulation to meet current building regulations for warm roof construction.

Whether you're replacing an ageing felt roof that's begun to blister and crack, or specifying a flat roof for a new extension, we'll recommend the system best suited to your budget, roof size and expected foot traffic.

We also carry out flat roof inspections and maintenance visits for landlords and commercial clients, identifying early signs of membrane wear, perished trims or blocked outlets before they develop into leaks — a small maintenance visit is almost always cheaper than emergency repairs after water has entered the building.

Most domestic flat roofs can be completed in just a few days, minimising disruption to your household.

Long-Lasting Performance

Quality EPDM and GRP systems are rated for 25-50 years of service life when installed correctly.

How It Works

Our Flat Roofing process

A clear, step-by-step approach so you always know what's happening and when.

  1. 1

    Assessment & System Selection

    We inspect the roof deck and discuss whether EPDM, GRP or felt best suits your project, budget and usage.

  2. 2

    Substrate Preparation

    The existing deck is checked, repaired or replaced as needed to provide a sound, dry base for the new covering.

  3. 3

    Insulation & Falls

    Insulation boards are laid to achieve current thermal performance standards, with tapered falls built in to prevent ponding.

  4. 4

    Membrane Installation

    The waterproof membrane is fully bonded or mechanically fixed according to the system specification.

  5. 5

    Trims & Upstands

    Edge trims, upstands and roof light kerbs are detailed to ensure a completely weathertight finish.

  6. 6

    Final Inspection

    We check falls, drainage and all detailing before handing the roof over, backed by our workmanship guarantee.
