Expert Flat Roofing Solutions in Dublin
Flat roofs are incredibly common across Dublin, particularly on home extensions, garages, dormer windows, and commercial properties. However, due to their low pitch, they are highly susceptible to the harsh Irish weather. Heavy rainfall can lead to pooling water, while the freeze-thaw cycle of winter can cause older materials to crack and blister.
At Haven Roof Specialists, we provide expert flat roofing in Dublin. We do not use outdated, unreliable materials. Instead, we install high-performance, modern flat roofing systems designed to remain completely watertight for decades, regardless of what the weather throws at them.
Torch-On Felt Roofing
Modern torch-on bitumen felt is a massive upgrade from the pour-and-roll felt of the past. It is highly durable, flexible, and cost-effective.
- Multi-layer system for maximum protection
- Excellent resistance to UV rays and cracking
- Proven performance in the Irish climate
- Ideal for garages, extensions, and dormers
EPDM Rubber Roofing
EPDM (Ethylene Propylene Diene Monomer) is a high-grade synthetic rubber roofing membrane known for its incredible longevity and seamless finish.
- Can last up to 50 years with minimal maintenance
- Often installed in a single, seamless sheet
- Highly flexible; expands and contracts without tearing
- Environmentally friendly and energy efficient
Signs Your Flat Roof Needs Replacing
Unlike pitched roofs where a missing slate is obvious, flat roof deterioration can be subtle until a major leak occurs. If you notice any of the following signs, it's time to arrange a professional flat roof inspection:
- Pooling Water (Ponding)If water sits on your flat roof for more than 48 hours after rain, the structure may have sagged, putting immense pressure on the membrane.
- Blistering & BubblingTrapped moisture under the felt expands when the sun heats it, causing bubbles that eventually crack and let water in.
- Cracking & SplittingAs traditional felt ages, it loses its elasticity. The constant expansion and contraction from Irish weather causes it to split at the seams.
- Internal DampnessBrown water stains on the ceiling directly beneath a flat roof indicate that the waterproof membrane has completely failed.
Why Choose Haven for Flat Roofing in Dublin?
Installing a flat roof requires absolute precision. A poorly installed flat roof will almost certainly leak within a few years. Our team has extensive experience in properly preparing the roof deck, ensuring adequate falls (slopes) for drainage, and expertly sealing every edge, corner, and upstand.
We remove all the old, deteriorated roofing material down to the timber deck. If the timber is rotten, we replace it to ensure a solid structural foundation. We then install the new system—whether torch-on felt or EPDM—with meticulous attention to detail, guaranteeing a finish that protects your home and looks incredibly neat.

Frequently Asked Questions About Flat Roofs
Which is better: torch-on felt or EPDM rubber?
Both are excellent systems. Torch-on felt is very cost-effective, highly durable, and the traditional standard in Ireland, usually lasting 15-20 years. EPDM rubber is a high-performance option; it costs slightly more upfront but is seamless, incredibly flexible, and can last up to 50 years. We can recommend the best option based on your specific roof and budget.
Do you use fibreglass (GRP) for flat roofs?
No, we do not install fibreglass (GRP) roofing. While popular in some areas, fibreglass is very rigid. In the fluctuating Irish climate, buildings naturally expand and contract. This rigidity often causes fibreglass roofs to crack and fail prematurely. We stick to flexible, proven systems like felt and EPDM.
How much does a new flat roof cost in Dublin?
The cost depends on the size of the roof, the material chosen (Felt vs. EPDM), and whether the underlying timber decking needs to be replaced due to rot. We provide completely free, detailed quotations after inspecting the roof so you have a precise, transparent price.
Can you repair a flat roof instead of replacing it?
If the roof is relatively new and the damage is localised (e.g., a small tear or a failed seal around a pipe), we can often repair it. However, if the roof is old, heavily blistered, or if water has rotted the timber underneath, a full replacement is the only safe and cost-effective long-term solution.
Does a flat roof need maintenance?
Modern flat roofs require very little maintenance. The most important thing is to keep the roof clear of debris (like autumn leaves) and ensure that the gutters and drainage outlets are unblocked so water can flow away freely.
