Roofing Services in Dún Laoghaire
Dún Laoghaire was built as a harbour town, and its roofs have weathered the sea for generations. The Victorian granite terraces along the front carry natural slate, lead valleys and chimney stacks, and standing right on the bay they take the full force of salt spray and onshore wind. That combination of fine old roofs and a hard maritime setting is exactly what we’ve spent 10 years working on here. Every job starts with a full inspection and no call-out fee.
From a slipped slate to a full re-roof, we cover domestic and commercial roofing across Dún Laoghaire and the surrounding harbour suburbs – slate, tile and flat roofing, gutters, fascia and emergency leaks. You’ll get a fixed written quote up front and the job done right the first time.

Trusted Roofing Contractors in Dún Laoghaire
MJ Roofing & More works on homes and commercial premises across Dún Laoghaire and the south harbour suburbs. From the seafront and town centre out to Glasthule, Sandycove, Monkstown and Dalkey. Wherever you are along this stretch of coast, we can get to you.
Dún Laoghaire’s harbour heritage gives it some of the most characterful roofs in Dublin and some of the most exposed. The Victorian and Regency terraces here run to natural slate, granite parapets, lead-lined valleys and tall chimney stacks, all of which age and need careful, matched repairs. Being right on the bay is the second challenge. Salt spray off the pier corrodes nails and fixings, onshore gales lift flashing and slates, and damp sea air feeds moss on shaded slopes. We understand both the old craft and the coastal wear, and we also handle the newer homes, apartments and flat-roof extensions around the wider area.
Whether it’s a coastal storm leak, a full re-roof, flat-roof waterproofing, or gutters and fascia, you’ll get honest advice, a clear written quote, and a tidy finish. Fully insured, with 10 years roofing homes and businesses across South Dublin.

Got Questions?
Frequently Asked Questions
How quickly can you reach a roof leak in Dún Laoghaire?
As quickly as we can, often the same day. We treat active leaks as a priority across the south harbour, so if water’s already coming in, call us directly rather than filling in a form and we’ll do our best to get to you fast.
Do you repair slate roofs on Dún Laoghaire's Victorian terraces?
Yes. It’s one of the things we do most here. The town’s granite terraces have natural slate roofs with lead valleys and chimney stacks, and slipped or cracked slates are common. We match the existing slate as closely as we can and fix the underlying cause, not just the surface.
Does the sea air damage Dún Laoghaire roofs?
It does. Salt spray off the harbour and pier corrodes nails and fixings, onshore wind lifts flashing and slates, and damp sea air helps moss take hold. It’s why seafront roofs need checking more often. We’ll tell you honestly what you need to stay weathertight.
Do you handle the tall chimney stacks on older harbour-town homes?
Yes. Many period homes here have large or multiple stacks that need re-pointing, re-flashing or capping over time. We rebuild and weatherproof them properly so they stop being a leak point.
Do you provide free written quotes in Dún Laoghaire?
Yes. The visit, basic inspection and the written quote are all free, with no call-out fee and no hidden extras.
Do you handle both homes and commercial buildings in Dún Laoghaire?
Yes. Houses, apartments, offices, retail units and other premises across Dún Laoghaire, with flexible scheduling to suit business hours.
