Flat Roofing

Flat roofs require specialist knowledge to prevent standing water and leaks. We install and repair high-performance GRP fibreglass, traditional felt, and lead flat roofing systems across London.

When You Need Flat Roofing Services

Pooling water or puddles forming on your flat roof after rain. Blistering, cracking, or tearing in old felt membrane surfaces. Water leaks penetrating through kitchen extensions, garages, or dormer roofs. Flaking fiberglass or exposed decking boards showing wear.

How We Do It

We inspect the underlying deck and insulation to check for hidden rot or moisture. We recommend the ideal flat roofing system, whether GRP fibreglass, torch-on felt, or lead. Our certified installers lay the seamless membrane or multi-layer felt system. We test the drainage and issue a written guarantee, including up to 25 years on GRP systems.

What to Expect

Most flat roof repairs are finished in a day, while full replacements take 2 to 3 days.
