Looking for roofing in Glenshaw? 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, we've 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.
Glenshaw is home base for Ireland Contracting. Our headquarters is right on William Flinn Highway. Shaler Township homeowners have trusted us with their roofs, siding, and gutters for decades, and being local means we respond fast when storms roll through.
Many Glenshaw and Shaler Township homes date to the post-war build-out, and their original or second-generation roofs are now well past their prime. Because our headquarters is right on William Flinn Highway, our crews are on Glenshaw roofs more than anywhere else, so we know the local rooflines and how North Hills snow load stresses these older pitches.
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.
