Flat Roof Installations &
Metal Trapezoidal Roof Repairs

High-Performance Flat Roofing Solutions

Seamless Protection for Extensions, Garages, and Commercial Units

Flat roofs require precision. Without the natural runoff of a pitched roof, the materials used must be 100% watertight and expertly installed to prevent "ponding." At Atlantic Renewables, we specialise in modern, high-durability flat roof systems that replace leaky felt with lifelong protection.


Our Specialist Flat Roof Systems

GRP Fibreglass Roofing

The Ultimate "Seamless" Roof

GRP (Glass Reinforced Polyester) is a cold-applied liquid resin that cures into a single, continuous membrane. With no seams or joints, it is virtually impossible for water to penetrate.

  • Best For: Balconies, walkways, and domestic extensions.
  • Durability: Impact-resistant and fire-retardant.
  • Lifespan: Engineered to last 30+ years with zero maintenance.

EPDM Rubber Roofing

Flexibility Meets Durability

We use high-grade EPDM (Ethylene Propylene Diene Monomer) rubber, often installed in a single large sheet to eliminate seams.

  • Best For: Garage roofs and large residential extensions.
  • Key Benefit: Highly flexible; it won't crack or split during UK temperature swings.
  • Eco-Friendly: Fully recyclable and extremely long-lasting.

Metal Trapezoidal Roof Repairs

Trapezoidal metal sheeting is the standard for many UK outbuildings, warehouses, and commercial units. However, "cut-edge corrosion" and failing fasteners can lead to costly internal damage.

We provide specialist repair services for trapezoidal profiled metal roofs, including:

Lap Seal Repairs: Preventing water from seeping between the metal sheets.

Fastener Replacement: Swapping rusted bolts for modern, capped, watertight fixings.

Protective Coatings: Applying weather-resistant coatings to halt rust and extend the life of the metal by 15+ years.

Sky-Light Replacement: Swapping aged, brittle GRP roof lights for modern, high-clarity panels to increase natural light.
