Looking for roofing in Mt. Lebanon? Ireland Contracting is a Pittsburgh roofing contractor specializing in complete roof replacements and new installations: a full tear-off and system replacement, not new shingles laid over old ones. Family-owned in Glenshaw since 1994, our Pittsburgh roofers have roofed homes from the North Hills to the South Hills and the eastern suburbs. 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.
Mt. Lebanon's houses are older than Allegheny County's as a whole: the median home here was built in 1953, and nearly a third of the municipality's houses predate 1940. Ireland Contracting roofs, sides, and replaces windows on those brick and stone Tudors and Colonials, with Owens Corning Platinum Preferred roofing crews and a repair technician who handles the small jobs older houses generate.
Mt. Lebanon's 1920s and 30s Tudors and Colonials have steep gables, stacked dormers, and brick chimneys, so a roof replacement here is mostly a flashing job with shingles on top. We tear off to the deck, cut new counterflashing into the chimney mortar, and step-flash every dormer wall rather than sealing over what the last roofer left.
Every roof replacement starts with a free, no-pressure inspection. We get on the roof and into the attic, and we assess the 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. You get a written, itemized estimate that shows exactly what's included, and a straight answer if what you actually need is a repair rather than a new roof.
What you get with an Ireland roof: a complete tear-off to the deck, replacement of any rotted or soft decking, synthetic underlayment across the whole roof, ice-and-water shield at the eaves, valleys, and around every penetration, new step and counter flashing at walls and chimneys, Owens Corning Duration architectural shingles with SureNail fastening, and ridge and soffit ventilation sized to the attic. Because we are manufacturer-certified and install the full system to spec, the roof qualifies for the strongest available Owens Corning warranties, coverage a layover or a mixed-brand roof can't get.
Most residential roofs are done in one to two days. Our crews protect landscaping and siding, run a magnet sweep for nails, haul every scrap of debris, and walk the finished roof with you before we leave. We register the warranty for you so it's on file with the manufacturer, not in a drawer.
Storm and hail damage is one of the most common ways a roof replacement gets paid for. We document the damage, meet the adjuster, and handle the insurance paperwork with you. For an active leak, missing shingles, or emergency tarping, our roof repair team takes small jobs too. You don't need a storm or a claim to call.
