Flat Roofing

Whether you need a new flat roof, a repair, or an upgrade to a modern membrane system, Watertight Roofing & Driveways delivers exceptional flat roofing solutions across Belfast and beyond. We use industry-leading materials designed for maximum longevity.

Flat roofs are commonplace across Belfast — found on extensions, garages, dormers and even entire commercial premises. However, they are particularly vulnerable to water pooling and membrane failure, especially in Northern Ireland's wet climate. At Watertight Roofing & Driveways, we install and repair flat roofs using the latest EPDM rubber and GRP fibreglass systems, which offer dramatically improved lifespans over traditional felt. Our skilled roofers ensure every flat roof we work on is genuinely watertight, properly insulated and built to last.
