Flat roof leaks have a habit of appearing at the worst possible time — during a heavy winter downpour, after a storm, or on a cold January morning when you open the garage door to find a puddle on the floor. By the time you notice it, the problem has usually been developing for longer than you think.
At Doherty Roofing, flat roof repairs and replacements are one of our most common jobs across County Tipperary. We cover everything from garage roof repairs and house extension roofs to outbuildings, bay windows and porches — using quality materials and proven installation methods that deliver lasting results in Tipperary's climate.
Based in Limerick, we are well placed to serve North Tipperary quickly and cover the full county. Fully insured, Safe Pass certified, free quotes and no call-out fees.
Tipperary is a county of significant weather variation. The open agricultural landscape of the Golden Vale provides limited shelter from the prevailing south-westerly weather systems that track across the county. Properties on upland positions — near the Silvermine Mountains in the north, the Arra Mountains above Lough Derg, and the Galtee range in the south — face more exposure than the sheltered lowland areas, and flat roofs in these positions experience more pronounced temperature fluctuation, more wind-driven rain and more freeze-thaw stress than equivalent roofs in sheltered positions.
The freeze-thaw cycles that affect North Tipperary particularly during cold winters are a specific challenge for flat roofing. Water that has penetrated a small crack or blister in the membrane freezes during cold nights and expands, progressively widening the defect with each cycle. A blister or crack that appears minor in autumn can become a significant membrane failure point by spring. In Tipperary's climate, early attention to flat roof defects is genuinely cost-saving rather than just desirable.
My garage roof has been leaking for a while — is it too late to repair it?
Not necessarily. If the leak is relatively recent and the underlying timber deck is still structurally sound, a repair or membrane replacement may be entirely appropriate. If the deck has been saturated for an extended period and shows signs of rot, deck repairs will be required as part of the project. Jim will inspect the full roof and give you an honest assessment of what is required and what it will cost — with no pressure to proceed.
How do I know if my flat roof needs repaired or fully replaced?
If the roof is relatively young and the problem is localised, a targeted repair is usually the right approach. If the roof is old, has multiple failure points or the underlying deck has been compromised, a full replacement is typically the more cost-effective long-term decision. The honest answer is always property-specific — which is why a free inspection is the most sensible first step.
Is EPDM better than felt for a Tipperary property?
For most Tipperary flat roof applications, yes. EPDM's flexibility handles the temperature cycling of Tipperary winters significantly better than rigid felt systems, and its thirty-year-plus lifespan means fewer replacement cycles over the life of the roof. The higher upfront cost is recovered through reduced maintenance and extended longevity.
Why does my extension roof keep leaking near the wall?
The junction between a flat roof and the house wall — the upstand — is the most common failure point on extension roofs across Tipperary. When the membrane or flashing at this junction fails, water tracks down behind the plasterboard and appears as damp at a distance from the actual entry point. We inspect and repair upstand failures specifically and carry out the correct flashing work to restore a permanently watertight seal.

Before we get into the detail, here is a straightforward reality check. These are the flat roof situations we encounter most frequently across Tipperary:
The Ageing Garage Roof
Most domestic garages across Tipperary were built with felt flat roofs. If your garage was built in the 1980s or 1990s, that felt roof is now between twenty-five and forty years old. If it has not been replaced or significantly repaired in that time, it is either already failing or very close to it. A damp patch on the garage ceiling or a musty smell when you open the door are the classic early warning signs. Left unaddressed, water works into the roof timbers, rots the deck and eventually the entire structure needs replacing rather than just the membrane.
The Leaking Extension Roof
House extensions with flat or low-pitched roofs are among the most common flat roof repair jobs we carry out in Tipperary. Extensions typically use felt, EPDM or GRP roofing, and the junction between the extension roof and the house wall — the upstand — is the most frequent point of failure. When the seal at this junction fails, water tracks down behind the internal plasterboard and appears as damp on the wall below, often a distance from where the actual entry point is. We locate the true source rather than patching the most obvious symptom.
The Roof That Has Already Been Repaired Once
A recurring leak on a flat roof that has already been repaired — usually with surface sealant or a patch — is one of the most frustrating problems a Tipperary homeowner faces. The reason is almost always the same: the previous repair addressed the visible surface symptom rather than diagnosing where water was actually entering. We inspect every flat roof we are called to thoroughly before agreeing any repair, ensuring we address the root cause rather than adding another temporary layer on top of an unresolved problem.
