Dún Laoghaire, Dublin
Pooling water and visible surface wear showed that this Dún Laoghaire flat roof needed attention before winter. We completed a full reseal, including the roof surface, edges and wall junctions, to restore continuous waterproof protection.
Dublin
A leaking flat roof in Dublin needed more than a local patch. We prepared the full roof area and applied Mariseal 250 across the surface, edges and upstands to create a continuous waterproof membrane.
Castleknock, Dublin 15
Flat roof leak repair in Castleknock, Dublin 15. We prepared the existing fibreglass roof and applied a continuous Mariseal 250 liquid waterproofing membrane, with careful detailing around the rooflight, perimeter edges and wall junctions to renew the roof’s weather protection.
Your flat roof is designed to fail.
A flat roof leak can mean moving furniture, catching drips and repainting the same ceiling. If water keeps entering, it can also wet insulation and damage timber decking beneath a surface that still looks intact.
For your Clonsilla roof, we investigate the covering, outlets and junctions, then check for signs of moisture beneath. That helps distinguish a repairable local defect from damage that needs a wider rebuild.
You get a written explanation of the proposed work and materials. Repair where it makes sense; replace damaged layers where needed, so you are paying to address the cause rather than conceal it.
Find the source before another patch leaves the underlying problem in place.

A free survey gives you the findings, repair options and price before you decide.
Every project follows the same playbook: diagnose, strip what is rotten, dry it out, rebuild and seal. We finish with the best system for your roof shape: premium liquid membranes like MARISEAL 250 for complex details, GRP for crisp edges or EPDM for large open spans. The win is the process that removes every weak link, not just the product.
Our workflow is designed around Irish weather: moisture readings decide what decking we remove, we add warm roof insulation when needed, then finish with the best system for your roof shape (liquid membrane, GRP or EPDM). Every edge, outlet and rooflight is detailed so wind-driven rain and frost cannot sneak back in.
We are a fully insured roofing company, with public liability cover in place for residential and commercial roofing work across Dublin.
We investigate every Clonsilla flat roof with moisture meters, inspection cameras and core samples when needed. That means we only replace what is damaged and design the right build-up for your property.
From our Blanchardstown base, we plan your Clonsilla repair around the roof construction, access and household or business needs. You know what will be removed, how the work will be arranged and what is included before committing.
Our crew is trained on liquid membranes, GRP and EPDM. We finish edges, rooflights and outlets properly so you get one continuous waterproof shell instead of seams and patches.
You get a written report, fixed price, progress photos and a completion pack. No vague allowances, no surprise extras, just the plan we agreed.
Choose with 10 years of cover for our workmanship within the agreed scope. If covered workmanship needs putting right, we carry out that work at no cost. We explain the terms and any applicable manufacturer warranty with your quote.
