Looking for roofing in Allegheny County? Ireland Contracting is a Pittsburgh roofing contractor specializing in complete roof replacements and new installations — a full tear-off and system replacement, not just new shingles laid over old ones. As an Owens Corning Platinum Preferred Contractor, a certification held by fewer than 1% of U.S. roofers, we install asphalt shingle roofing systems backed by manufacturer warranties of up to 50 years.
Allegheny County is Ireland Contracting's home turf — our headquarters sits in Glenshaw, just north of Pittsburgh. From the North Hills to the South Hills and the eastern suburbs, we've protected county homes from heavy snow, wind, and freeze-thaw cycles for over 30 years.
From the North Hills down through the South Hills and the eastern suburbs, Allegheny County's housing runs from century-old city homes to newer developments — each needing a different roofing approach. As a county-based contractor headquartered in Glenshaw, we've roofed them all.
Every roof replacement starts with a free, no-pressure inspection. We assess your decking, ventilation, flashing, and underlayment — not just the surface shingles — so the new system performs for its full lifespan in Western Pennsylvania's freeze-thaw climate.
Because we are manufacturer-certified, we install complete roofing systems to spec, which unlocks the strongest available warranties. Our crews protect your property daily and clean up thoroughly when the job is done.
Storm and hail damage is one of the most common ways a roof replacement gets paid for — we document the damage and handle the insurance paperwork with you. For active leaks, missing shingles, or emergency storm response, our roof repair and storm-damage service has you covered.
