Flat roof repairs & installation
Leaking flat roofs, water pooling around outlets, failed flashing and split roof coverings can all lead to water ingress. We assess the extent of the damage and explain whether a targeted flat roof repair or a full replacement is the more appropriate solution. If the issue extends beyond the flat roof, we can also help with roof repairs elsewhere on the property.
Water getting through, damp patches or signs of moisture inside your property.
Water sitting on the roof instead of draining away properly after rainfall.
Splits, punctures or deterioration in the existing roof covering.
An older roof that is becoming brittle, worn or failing in several areas.
Repair or replacement for residential extensions, garages and other smaller flat roofs.
New flat roofing systems for extensions, conversions and other roofing projects.
Not sure what’s causing the problem? That’s fine — we can inspect the roof first and talk you through what we find.
Flat roof repair or replacement
Not every leaking or damaged flat roof needs to be replaced. We’ll inspect the condition of the roof first, explain what we find and recommend the option that makes the most sense.
A repair may be enough where the problem is isolated and the rest of the roof is still in reasonable condition.
Replacement may make more sense where leaks keep returning or the roof covering is failing across several areas.
We provide free, no-obligation estimates and explain the proposed work and materials in writing. Ask our team about the terms and any workmanship or product warranties applicable to your quotation.
Flat roofing systems
We install torch-on felt and liquid rubber waterproofing systems for garages, extensions, bay roofs and other suitable flat roof areas in Dublin. The right specification depends on the roof structure, drainage, existing covering and details such as upstands and outlets. We’ll explain the options after assessing your property.
Torch-on felt uses heat-bonded bituminous membranes to create a waterproof roof covering. It can be suitable for garages, home extensions and other flat roofs where the substrate, roof details and safe installation conditions allow this system.
Liquid-applied rubber waterproofing forms a continuous coating over a prepared, compatible substrate. It can be useful where a flat roof has complex junctions, awkward shapes or multiple details. Suitability and preparation requirements are assessed for each job.

Questions You Might Have
Unsure whether your roof needs a small repair or something more substantial? Here are straightforward answers to some of the things homeowners usually want to know before getting someone out to take a look.
Not every leaking flat roof needs to be replaced. If the problem is isolated and the rest of the roof is still in reasonable condition, a repair may be enough. If leaks keep returning or the roof covering is deteriorating across several areas, replacement may be the more sensible option. We inspect the roof first and explain the options before recommending any work.
The cost of flat roof repairs in Dublin depends on the source of the leak, the size of the damaged area, roof access, materials and any underlying issues. We assess the work before providing a free, written quotation, so you can decide whether to proceed.
Flat roof replacement costs depend on the roof’s dimensions, condition, access, insulation and drainage requirements, and the chosen waterproofing system. We install torch-on felt and liquid rubber systems and provide an itemised quote after assessing the work needed.
Common warning signs include leaks inside the property, damp patches on ceilings, cracks or splits in the roof covering, blistering, damaged edges or flashing, and water sitting on the roof after rain. It is usually best to have the roof checked before a small problem turns into a bigger one.
Standing water can be caused by blocked drainage, damaged outlets or areas of the roof that are no longer draining properly. A small amount of water immediately after heavy rain is not always a major concern, but repeated pooling in the same area is worth investigating.
We install torch-on felt and liquid rubber roofing systems. The right option depends on the roof itself, the condition of the existing covering and what is most suitable for the job. We’ll inspect it first and talk you through the option we recommend.
Yes. We repair and replace roofs on garages, extensions and other domestic flat-roofed areas. Whether you have a leak, visible wear or an older roof that needs attention, we can inspect it and advise whether a repair or replacement makes the most sense.
Estimates are free, with the proposed work and price confirmed in writing before you make a decision. Warranty terms depend on the system and work agreed; ask our team to confirm them in your quote.
