A flat roof that is performing well is one of the most efficient and practical roofing solutions available. A flat roof that is failing, however, can be one of the most frustrating and damaging problems a homeowner faces. Leaks develop, water pools, ceilings stain, and the damage spreads quickly if the problem is not identified and addressed by someone who knows exactly what they are doing.
At Doherty Roofing, flat roof repairs are one of our core services. We carry out professional flat roof repairs and replacements for homeowners across Limerick, Clare and Tipperary — on house extensions, garage roofs, outbuildings, bay windows and any other flat or low-pitched roofed structure on your property. Jim and his team have the knowledge and experience to diagnose flat roof problems accurately and deliver lasting solutions using quality materials suited to the demands of the Irish climate.
We are fully insured and Safe Pass certified, and we provide free, no-obligation quotes on all flat roof work. There are no call-out fees, no pressure and no unnecessary upselling — just honest, professional advice from a local roofer who takes pride in every job.

From our base in Limerick, we carry out flat roof repairs and replacements across a wide area. We regularly work in Limerick city — including Dooradoyle, Castletroy, Raheen, Caherdavin, Corbally, Annacotty and Moyross — as well as all areas of County Limerick including Adare, Newcastle West, Rathkeale, Kilmallock, Abbeyfeale and Caherconlish.
We also cover County Clare including Ennis, Shannon, Sixmilebridge, Killaloe, Kilrush and Scariff, and County Tipperary including Nenagh, Thurles, Roscrea, Tipperary Town and Templemore.
Whether your property is in the heart of Limerick city or in a rural townland on the Clare or Tipperary border, Doherty Roofing can come to you.
This depends on the material and the quality of the original installation. A well-installed torch-on felt roof typically lasts between fifteen and twenty-five years. A fibreglass or GRP roof can last twenty-five years or more, and a quality EPDM rubber roof can last thirty years or beyond with minimal maintenance. Regular inspection and prompt repair of minor issues significantly extends the lifespan of any flat roof system.
The cost varies considerably depending on the nature and extent of the repair, the material involved and the size of the roof area affected. A minor targeted repair to a specific leak is significantly less expensive than a full roof replacement. Doherty Roofing provides free, detailed quotes with no hidden charges so you will always know the full cost before any work begins.
This depends on the age and overall condition of your garage roof. If the roof is relatively new and the damage is localised, a repair is usually the right course of action. If the roof is old, has multiple areas of deterioration, or the underlying deck has been damaged by long-term water ingress, a full replacement is often the more cost-effective long-term solution. Jim will inspect your garage roof and give you an honest, straightforward recommendation.
Recurring leaks on a flat roof are usually the result of one of two things — either the original repair only addressed the visible symptom rather than the true source of the water ingress, or the roof has multiple failure points that need to be addressed comprehensively rather than one at a time. Doherty Roofing carries out thorough inspections to identify all areas of concern before any repair work begins, ensuring we address the root cause rather than just patching the most obvious problem.
Yes. We carry out flat roof repairs and replacements on all types of flat roofed structures including house extensions, garages, outbuildings, bay windows, porches and flat roofed sections of otherwise pitched-roof properties.


One of the most common flat roof repair jobs we carry out across Limerick is garage roof repair and replacement. The vast majority of domestic garages in Limerick — whether attached to the house or freestanding — have flat or low-pitched roofs, and these roofs have a finite lifespan that many homeowners underestimate.
A standard felt garage roof, if originally installed to a reasonable standard, will typically last between ten and twenty years before it begins to fail. Older felt systems, particularly those installed with single-layer torch-on felt, may begin showing problems even sooner — especially if they were not laid on adequate decking or if drainage was not properly considered during installation.
When a garage roof begins to fail, the signs are often subtle at first. You might notice a damp patch on the garage ceiling, a musty smell when you open the door, or water marks running down an internal wall. Left unaddressed, these early warning signs develop into active leaks, rotting roof timbers, damaged stored belongings and, in attached garages, water ingress into the adjoining wall of the house itself.
Doherty Roofing carries out garage roof repairs and full garage roof replacements across Limerick city and county, Clare and Tipperary. Whether your garage roof needs a targeted repair to a specific area of membrane damage or a complete strip and relay, Jim will inspect it thoroughly and give you a clear, honest assessment of what is required and what it will cost.
