Flat & Felt Roofing in Laois
Flat Roofs Get Blamed for Problems That Are Actually Installation Faults
Flat roofs have a bad name in Ireland, and most of it is undeserved. The roof itself isn't usually the problem — it's how it went in. A flat roof needs a proper fall built into it so water actually drains toward the gutter, and when that slope is missing or too shallow, water sits on the surface instead of running off.
Left long enough, that standing water finds its way through even a roof covering that looks intact, which is why so many flat roofs in Laois develop leaks that seem to come from nowhere.
We see this constantly on garage roofs and extensions across the county — a felt or fibreglass roof that's only a few years old, already letting water in, not because the material failed but because it was never given anywhere to drain to in the first place. Get the installation right and a modern flat roof system will comfortably outlast what most people expect from one.
We repair and replace flat roofs across all of County Laois — Portlaoise, Portarlington, Mountmellick, Abbeyleix, Stradbally, Mountrath, Rathdowney and the areas around them. Felt, EPDM rubber and fibreglass, fitted properly with a fall that actually works.

Why Flat Roofs Actually Fail in Laois
The biggest cause of flat roof problems isn't the material, it's the lack of fall. Every flat roof needs to slope toward a drainage point, usually a gutter, so rainwater runs off rather than sitting on the surface.
Without that slope — sometimes because it was never built in, sometimes because timber underneath has sagged over time — water pools after every rainfall. Fibreglass can hold standing water for a long time without an obvious leak, but eventually that moisture works its way into the structure underneath, by which point the damage is well advanced.
Installation quality is the other major factor. EPDM that's been poorly fitted can shrink and wrinkle over time, creating weak points at the folds. Felt that's been laid with insufficient overlap at the seams will lift in wind and let water track underneath. None of these are flaws in the material itself — they're shortcuts taken during installation that don't show up as a problem until months or years later.
This is exactly why we won't quote a flat roof job without checking the fall and the deck underneath first. A roof covering is only as good as what it's been fitted onto.

Signs Your Flat Roof Needs Attention
Watch for standing water that's still visible more than 48 hours after rain — flat roofs should drain fully within that window, and water sitting longer than that points to a fall problem rather than just normal weather.
Bubbling or blistering on the surface, particularly on felt or older fibreglass, usually means moisture has gotten underneath the membrane and is trapped there.
On fibreglass specifically, look for a texture like peeling paint — this is delamination, where the layers are separating, and it's a sign the roof is nearing the end of its life rather than something to patch over.
And damp patches on the ceiling directly below a flat roof section are the clearest sign of all, though by the time you see this internally, the leak has usually been present for some time.
Flat Roof Questions From Laois Homeowners
Both are significantly better than old-style felt and last well when properly installed. EPDM is a single rubber sheet, so a leak is usually easy to trace and patch. GRP fibreglass is fully bonded and seamless, which means leaks tend to be more localised and easier to isolate, but repairs to delaminated sections are more involved. Which suits your roof depends on its size, shape and what's already there.
This is almost always an installation issue rather than a material failure — most commonly insufficient fall, meaning water has been pooling on the surface since the day it was fitted rather than draining away properly.
It depends on the extent of the damage and the condition of the deck underneath. Localised splits, punctures or seam failures are usually repairable. Widespread delamination, multiple recurring leaks, or a deck that's been compromised by long-term water ingress generally point toward replacement being the better long-term option.
Yes, more than most people realise. Clearing debris and checking for pooling once or twice a year catches small problems before they become leaks, particularly on roofs near trees where leaves and moss can block drainage points.
A standard garage or extension roof typically takes one to two days, depending on size and whether the existing covering needs to be fully stripped back first.
Yes. All flat roof repairs and installations come with a written guarantee, with terms confirmed before work begins.
