Roofing Services in Castleknock
Castleknock is one of West Dublin’s leafiest, most sought-after suburbs, and its roofs come with that setting. Beside the Phoenix Park and wrapped in mature trees, the area is full of larger detached and period homes with slate, tile, lead valleys and chimney stacks – and all that greenery means gutters clog with leaves and moss creeps across shaded slopes. We’re based just up the road in Ongar, the same D15 postcode, and after 10 years here we know these roofs well. 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 Castleknock and the surrounding D15 area. 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 Castleknock
MJ Roofing & More is based right here in D15, in Ongar, minutes from Castleknock. That makes us genuinely local across the village, Carpenterstown, Laurel Lodge, Diswellstown and out toward Clonsilla. Being on your doorstep means fast response times, especially when there’s a leak that won’t wait.
Castleknock’s mix of housing calls for a bit of everything. Around the village and castle there are older and larger detached homes with natural slate, lead-lined valleys and tall chimney stacks that need careful, matched repairs. The estates built from the 1980s onward, run to concrete-tile and dry-ridge roofs that slip and loosen with age, and flat-roof extensions are common throughout. The area’s heavy tree cover, so close to the Phoenix Park, adds its own problem, leaves fill gutters and valleys until they back up, and damp, north-facing slopes grow moss that lifts slates over time. We handle all of it.
Whether it’s a storm leak, a full re-roof, flat-roof waterproofing, moss treatment 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 D15.

Got Questions?
Frequently Asked Questions
How quickly can you reach a roof leak in Castleknock?
Very quickly, this is our own area. Our yard is in Ongar, the same D15 postcode, so for most of Castleknock we’re only minutes away and can often attend the same day. If water’s already coming in, call us directly and we’ll get to you as fast as we can.
Do the trees near the Phoenix Park cause roof problems in Castleknock?
They can. Castleknock’s heavy tree cover drops leaves into gutters and valleys, which back up and cause leaks, and damp, shaded slopes grow moss that lifts and cracks slates. Regular gutter clearing and moss treatment usually keeps it in check. We’ll advise you on what you need.
Do you work on the larger detached and period homes in Castleknock?
Yes, often. Many homes here are larger detached or period properties with natural slate, lead valleys and chimney stacks. We repair these with the care older roofs need, matching existing slate and fixing the underlying cause, not just the surface.
Do you also work on the newer estate roofs in the area?
Yes. Estates like Laurel Lodge, Carpenterstown and Roselawn have concrete-tile and dry-ridge roofs, and slipped tiles, loose ridges and lifted flashing are everyday jobs for us.
Do you provide free written quotes in Castleknock?
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 Castleknock?
Yes. Houses, apartments, offices, retail units and other premises across Castleknock, with flexible scheduling to suit business hours.
