Roof Repairs &
Roofing Services in Blanchardstown

Blanchardstown is our own doorstep. We’re based in Ongar – so when a roof leaks anywhere in Blanchardstown, we’re usually only minutes away. It’s a big, busy suburb. Thousands of tile-and-flat estate roofs, plus a large retail and commercial building around the town centre. After 10 years working these streets we know exactly how the roofs here age. Every job starts with a full inspection and no call-out fee.

From a slipped tile to a full re-roof, we cover domestic and commercial roofing across Blanchardstown and the surrounding D15 estates. 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.

MJ Roofing & More is based right here in D15, in Ongar, a stone’s throw from Blanchardstown. That makes us genuinely local across the whole area, from Corduff and Mulhuddart to Clonsilla, Tyrrelstown and Castleknock. Being on your doorstep means fast response times, especially when there’s a leak that won’t wait.

Blanchardstown grew quickly from the 1980s and 1990s onward, so most homes here have concrete-tile roofs and dry-ridge systems that age in predictable ways. Tiles slip, mortar-bedded ridges loosen, and flat-roof extensions start to let water in at the joints. The town also has one of the largest shopping and commercial centres in the country, along with retail parks and units all along the N3 corridor, which means plenty of flat commercial roofs too. We work on all of it, and we handle the older homes and period stock around Castleknock village with the same care.

Whether it’s a storm leak, a full re-roof, a flat-roof repair, 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 Blanchardstown?

Very quickly. This is our own area. Our yard is in Ongar, the same D15, so for most of Blanchardstown 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 you specialise in the estate roofs common in Blanchardstown?

Yes. Most Blanchardstown homes have concrete-tile roofs and dry-ridge systems from the 1980s and 1990s, and we work on them constantly across estates like Corduff, Mulhuddart and Tyrrelstown. Slipped tiles, loose ridges and lifted flashing are our everyday jobs.

My flat-roof extension is leaking - can you fix it?

Almost certainly. Flat-roof extensions are very common on Blanchardstown houses and a frequent source of leaks. We trace the real source rather than just patching the surface, and can repair or re-cover the flat roof to last.

Do you work on commercial and retail roofs around Blanchardstown?

Yes. The area has a large retail and commercial centre with plenty of flat-roofed units along the N3 corridor, and we handle commercial repairs, waterproofing and re-covers with scheduling that suits business hours.
