Flat Roofing in Dublin
Garage, extension and dormer flat roofs fail for the same reasons: ponding water, tired felt and bad detailing at the upstands. We rebuild the falls properly and finish in EPDM rubber, fibreglass GRP or high-performance torch-on felt.
- EPDM rubber single-ply — seamless, 30-year design life
- Fibreglass GRP for balconies and walk-on areas
- Torch-on felt for larger or cut-to-falls roofs
- New firrings to correct ponding, plus insulation upgrades
- New trims, outlets and upstand detailing as standard

Flat Roofing — common questions
Which flat roof system lasts longest?
EPDM rubber is seamless and typically carries a 30-year design life. GRP is best where the roof is walked on. Felt remains the most cost-effective on larger areas.
Can you fix ponding water?
Yes — we add firrings to build a proper fall towards a new outlet rather than covering over the problem.
