Flat Roofing & Flat Roof Repairs in Dublin
Flat roofs can develop leaks long before they look worn out from the ground. On a domestic extension, garage or porch, the covering, the junctions and the drainage all have to keep working together, and a failure at any one of them shows up inside.
We repair residential flat roofs where the structure below is sound, and replace the covering where it has reached the end of its useful life.

Common flat roof symptoms
- Water ingress on the ceiling below the flat section
- Pooling or standing water that remains long after rain
- Splits, cracks or damage across the covering
- Failed upstands where the flat roof meets a wall
- Flashing and detail problems at the junction with the main roof
- Previous patch repairs that have lifted or failed again
How a flat roof repair is assessed
1.Covering and condition
What the roof is currently covered with, and how much life is left in it, decides whether a repair is sensible or a false economy.
2.Extent of the damage
A single split in an otherwise sound roof is a very different job from a covering that has failed across the whole area.
3.Drainage and falls
Outlets, falls and standing water are checked. Many repeat flat roof failures are drainage problems rather than covering problems.
4.Details, junctions and access
Upstands, trims and the abutment with the main roof are where flat roofs usually leak. Access also affects how the work is carried out and priced.
Is the deck wet?
If the boarding below the covering has taken in water, laying a new surface over it only hides the problem. Where a roof feels soft or springy underfoot, that needs checking before any repair is priced.
Why pooling water matters
A little standing water after heavy rain is normal. Water that sits for days points to inadequate falls or a blocked outlet, adds weight, and shortens the life of whatever the roof is covered with.
The flat roof systems we work with
Four systems cover most domestic flat roofs in Dublin: felt, laid in bonded layers and long established; GRP fibreglass, applied wet and cured into a hard seamless laminate; EPDM rubber, a single-ply membrane laid with few or no joints across the roof; and liquid-applied waterproofing, brushed and rolled over prepared surfaces and awkward details. Each has its own page below under related services. Which suits your roof depends on the deck, the shape, the detailing, the drainage and the condition of what is there now.

FAQ
Flat Roofing — common questions
Can a leaking flat roof be repaired?
Often, yes. Localised splits, damaged detailing and failed upstands can usually be repaired where the rest of the covering and the structure below are sound.
Why is water pooling on my flat roof?
Usually because the falls are too shallow, the structure has deflected slightly, or the outlet is blocked. It is worth dealing with, as standing water shortens the life of the roof.
Do you repair flat roofs on extensions?
Yes — extensions, garages, porches and dormers are the flat roofs we work on most often on Dublin homes.
How do I know whether to repair or re-cover?
It comes down to the condition of the existing covering and how widespread the problem is. One failed detail is a repair; a covering failing in several places is usually better re-covered.
My extension ceiling is staining — is it definitely the flat roof?
Not necessarily. Water can enter at the junction with the main roof, at the wall abutment or through the flashing above, so the whole area gets checked.
