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 Castleknock 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.

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.
Victorian terraces, Edwardian homes and modern extensions need discreet detailing. We replace saturated decking, improve insulation, and finish with seamless membranes that protect stone, brick and timber without bulky trims.
We are a fully insured roofing company, with public liability cover in place for residential and commercial roofing work across Dublin.
We investigate every Castleknock 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 Castleknock 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.
