Flat Roofing (GRP, EPDM & Felt)

ApexShield Roofing installs resilient Firestone EPDM rubber membranes, seamless GRP fibreglass laminates, and advanced torch-on polyester systems engineered to withstand standing water, UV degradation, and UK temperature swings.

Problems We Diagnose & Solve
If your roof is exhibiting any of these signs, prompt assessment prevents costly structural timber damp and water damage.
Ponding Water & Inadequate Fall
Water accumulating in pools due to sagging timber decking or insufficient drainage falls, speeding up material breakdown.
Blistering & Cracked Seams
Ageing mineral felt where thermal expansion tears joints, allowing moisture into the underlying wood joists.
Leaking Deck Junctions & Upstands
Failed seals where the flat roof abuts exterior cavity walls or chimney brickwork.
Durable Workmanship Engineered for North West Weather
We use time-tested British roofing specifications, premium breathable membranes, treated structural timber, and high-performance leadwork to deliver a watertight finish.
One-Piece EPDM Rubber Installation
Custom-measured single sheet membranes with zero joints on standard domestic extensions, eliminating seam leakage.
GRP Fibreglass Layup
Tough composite resins reinforced with glass fibre matting and finished with UV-resistant slate grey topcoat.
Firring Strips for Correct Water Fall
Installing tapered timber firrings before decking to ensure rainwater sheds cleanly toward gutters.

Our Flat Roofing (GRP, EPDM & Felt) Process
From initial assessment to final site cleanup, here is how we handle your roofing project step by step.

Substrate Preparation
Stripping failed coverings and installing new tongue-and-groove OSB3 sterling boards with correct expansion gaps.
Thermal Insulation Integration
Adding rigid foil-faced PIR insulation if upgrading to a warm roof construction to prevent condensation.
Membrane Application & Trims
Bonding the chosen GRP or EPDM system, fitting preformed drip trims, and dressing upstands into brickwork mortar lines.

We water-test the perimeter drainage points and issue your written warranty certificate.
