Real reviews from your neighbours
“New build extension - wanted it done right from the start. MARISEAL 250 was the clear choice after research. Seamless, modern technology, 20+ years lifespan. Installation was excellent, team was professional. 15 months later, absolutely perfect. No regrets paying for quality.”
- Mark Hughes
“Garage roof needed replacing at 9 years - original felt was failing. They explained MARISEAL 250 benefits clearly - liquid membrane, no seams, proven durability. Fair price, clean installation, completed in two days. 12 months on, bone dry. Should last decades now.”
- Rachel Kennedy
Your flat roof is designed to fail.
Flat roofs rarely fail because of one dramatic hole. They fail because trapped moisture rots decking, blisters felt and overwhelms outlets. Buckets and silicone patches hide the symptom for a storm or two but never address the source.
Every time you pay for another quick torch-on strip in Hollystown, water continues to migrate underneath, saturating insulation and timber. By year three the plywood and joists are compromised, so repairs take twice as long and cost twice as much.
Meanwhile ceilings stain, mould shows up on survey reports and insurers start asking questions. You pay in stress, downtime and lost property value long before you replace the roof.
Five years of patching costs more than rebuilding it properly once.
Fix the source once. Rebuild it properly. Stay dry for decades.
Proper rebuild: €2,800 once. 20+ years of dry ceilings. Zero late-night buckets.

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 investigate every Hollystown 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.
Based in Dublin, we work across Hollystown weekly. We know the estate layouts, access routes and common construction quirks, so planning, waste removal and communication stay smooth.
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.
10-year workmanship guarantee, manufacturer warranties up to 20 years and optional maintenance plans keep your flat roof protected long term.
