Flat Roofs

Flat roofs require specialized waterproofing techniques to prevent pooling water and membrane degradation. We install robust, modern flat roofing systems that offer superior protection against UV rays, heavy rain, and thermal movement.

When You Need Flat Roof Services

Pooling water forming large puddles on your garage or extension roof days after rain stops. Bubbling, cracking, or blistering visible across the felt or rubber membrane surface. Internal water leaks dripping through the ceiling directly beneath your flat roof extension. Old mineral felt that has worn away, exposing the timber deck underneath to moisture.

How We Do It

We inspect the underlying timber deck for rot and evaluate the drainage falls across the flat roof surface. We remove failed waterproofing layers and repair or replace any compromised plywood decking boards. We lay high-specification insulation boards followed by a seamless, torch-on felt, EPDM rubber, or fibreglass membrane. We finish all perimeter trims and flashings to guarantee a watertight seal against parapet walls and fascias.

What to Expect

Most flat roof replacements or installations are completed within 1 to 3 days.
