Roofing Contractor in Pittsburgh, PA

Pittsburgh's Owens Corning Platinum Preferred roofing contractor for complete roof replacements and new installations built to last decades.

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.

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.

Why Pittsburgh roofs fail early

Western Pennsylvania is hard on roofs. Repeated freeze-thaw cycles work meltwater under shingles and into cracks, then expand it as it refreezes — the single biggest driver of premature shingle failure and leaks in the Pittsburgh area. Heavy wet snow adds load, and ice dams form at the eaves when escaping attic heat melts snow that refreezes at the cold roof edge.

The region's older housing stock compounds it: many Pittsburgh-area homes still have original or single-layer roofs with under-built ventilation that traps attic heat and moisture and shortens roof life. We design each replacement around ventilation and ice-and-water protection at the eaves and valleys — not just the shingles you see.

Our roofing process

  1. 1 Free inspection & estimate. We inspect decking, ventilation, flashing, and shingles, then give you a written, itemized estimate — no pressure.
  2. 2 Materials & scheduling. You choose your shingle line and color; we schedule the tear-off and handle permits and, where applicable, insurance coordination.
  3. 3 Tear-off & deck check. We strip the old roof to the deck, inspect for rot, and replace any compromised decking before anything goes back on.
  4. 4 System installation. We install underlayment, ice-and-water shield at the eaves and valleys, new flashing, shingles, and ventilation to manufacturer spec.
  5. 5 Cleanup & warranty. We magnet-sweep for nails, haul away all debris, do a final walkthrough, and register your manufacturer warranty.

Roofing FAQs

How much does a new roof cost in Pittsburgh?

The cost of a roof replacement depends on your roof's size and pitch, the number of layers to tear off, and the shingle line you choose. Every roof is different, so we provide a free, itemized estimate rather than a one-size quote.

How long does a new roof last?

Asphalt shingle roofs typically last 20–25 years. Lifespan depends on ventilation, installation quality, and maintenance.

How long does a roof replacement take?

Most residential roof replacements are completed in one to two days, weather permitting. Larger or steeper roofs can take longer.

Can you install a new roof over the old shingles?

We don't recommend it. A layover hides deck damage and voids many manufacturer warranties — we do a complete tear-off so the new system performs for its full lifespan.

When is the best time to replace a roof in Pittsburgh?

Spring through fall is ideal, but we install year-round. Shingles seal best in moderate temperatures, and we take extra steps to install correctly in colder weather.

Will you help with my insurance claim?

Yes. We document storm and hail damage and handle the insurance paperwork with you, which is one of the most common ways our roof replacements are paid for.

Are you licensed and insured?

Yes. Ireland Contracting is licensed, bonded, and insured under PA License #026195 and has been in business since 1994.
