Felt Roofing & Felt Roof Repairs in Dublin
Plenty of Dublin homes have a felt flat roof somewhere: over a garage, a rear extension, a porch or a small outbuilding. They are straightforward roofs, and when one starts leaking the question is nearly always the same — patch it, or recover it?
We repair felt roofs and we replace them, and which we recommend comes down to how much of the covering has gone and what condition the deck below is in.

Common felt roof problems
- A split or tear in the covering, often along a seam or at a change of level
- Blistering or bubbling across the surface
- Water ingress showing on the ceiling below
- Failed laps or junctions where the felt meets a wall or upstand
- Felt pulling away at verges, drips or around an outlet
- Ponding water and a surface that has dried out and become brittle
How we approach the job
1.Check the deck, not just the felt
Soft or springy areas underfoot usually mean water has been getting in for some time. A new covering over a deteriorated deck is money wasted, so this is the first thing we establish.
2.Trace the entry point
On a flat roof the leak inside is often some distance from the actual defect. We look at seams, upstands, outlets and abutments rather than assuming it is where the drip appears.
3.Repair or recover, with reasons
A single split on a sound roof is a repair. A covering that has dried out and split in several places is a recover, and we will explain which one we think you are looking at.
4.Sort the drainage while the roof is open
Falls and outlets are checked as part of the work so the new covering is not asked to hold standing water for the rest of its life.
When repair still makes sense
If the damage is contained, the rest of the covering is sound and the deck is dry, a repair is usually good value and can be done quickly. Repeated patching of a roof that keeps failing in new places is not.
What replacement involves
Replacement means stripping the old covering, inspecting and making good the deck, confirming the falls, and forming the upstands, edges and outlet details properly. Access and the amount of deck repair needed are the two things that most affect the scope.

FAQ
Felt Roofing — common questions
Can a leaking felt roof be repaired?
Often, yes. Isolated splits, failed laps and damaged detailing can normally be repaired where the rest of the covering and the deck below are in reasonable condition.
When might a felt roof need replacing?
When the covering has become brittle and is splitting in several places, when it has been patched repeatedly, or when the deck underneath has taken in water.
Can felt roofing be used on an extension?
Yes — extensions, garages and porches are the most common domestic uses. Whether it is the best covering for a particular extension depends on the deck, falls and detailing, which we check first.
What causes blisters on a felt roof?
Generally moisture or air trapped beneath the covering expanding in warm weather. Small blisters are not always a leak, but they are worth looking at as they can eventually split.
Is felt or fibreglass better?
Neither is automatically better. It depends on the roof — size, deck, falls, details and use. We look at the roof and explain the trade-offs rather than pushing one covering.
