Pittsburgh Roof Inspection Service Areas

Why location matters more here than in most cities

Start at Pittsburgh Roof Inspection for the main service. If you're weighing a free contractor visit against a paid written report — for a sale, a purchase, or a dispute — the roof inspection cost guide explains which one your situation calls for.

Allegheny County is 130 separate municipalities packed into 730 square miles, and the housing changes character every few miles. A 1925 brick foursquare in Dormont, a hillside house in Troy Hill with a roof you can practically step onto from the street above it, and a 2005 colonial in Cranberry are three genuinely different roofing problems. Access, pitch, material, and drainage all shift.

The weather is the constant. About 38 inches of rain, 44 inches of snow, and — the part that does the real damage — a winter that freezes and thaws repeatedly instead of staying cold. Water gets into a flashing seam, freezes, expands, opens the seam a little wider, and does it again next week. That's why so many Pittsburgh leaks trace back to chimneys and sidewalls rather than the shingles themselves.

The other constant is age. Roughly 47% of city housing predates 1940 — four times the national rate — and the inner boroughs aren't far behind. Old houses mean slate, masonry chimneys, dormers, and valleys that were built by hand.

Pittsburgh city neighborhoods

Squirrel Hill, Shadyside, Point Breeze, Highland Park, Bloomfield, Lawrenceville, the North Side, Mount Washington, Brookline, Beechview, the South Side slopes.

City work is defined by two things: hills and old roofs. On a hillside street, one side of the house may be three stories off the ground while the other is nearly at grade — which changes how a roof gets accessed, staged, and inspected safely. Plenty of the East End housing still carries original slate, and slate is its own trade. A roofer who works exclusively in asphalt can walk a slate roof and break more than they find.

Row houses and close-set lots add a wrinkle: shared or near-shared walls mean water entering at one roof-to-wall transition can show up somewhere you'd never connect to it. Tell the inspector where you see it inside, not where you assume it's coming from.

South Hills

Mt. Lebanon, Dormont, Bethel Park, Upper St. Clair, Baldwin, Brentwood, Whitehall, Castle Shannon, South Park, West Mifflin, Pleasant Hills.

The old streetcar boroughs — Dormont and Mt. Lebanon in particular — are dense with 1920s and '30s brick homes, tile and slate roofs, real chimneys, and mature trees hanging over all of it. Two things dominate the calls: chimney flashing that's reached the end of its life, and gutters that can't keep up with decades of leaf load. A clogged gutter backing water under the shingle edge produces an interior stain that looks exactly like a roof failure.

Farther south — Upper St. Clair, South Park, Bethel Park — the houses get newer and bigger, with more roof planes, more valleys, skylights, and additions. More transitions means more places to fail, and a ground-level look is close to worthless on a complicated roof.

East suburbs

Monroeville, Penn Hills, Plum, Verona, Wilkinsburg, Swissvale, Edgewood, Forest Hills, Churchill, Murrysville.

Wilkinsburg, Swissvale, and Edgewood are Victorian-era boroughs — steep pitches, turrets and dormers, slate, and often a long unwritten history of patches by whoever was cheapest that year. Layered repairs are common, and they matter, because a patch over a patch over the wrong entry point can hide the actual problem for years.

Monroeville, Plum, and Penn Hills mix eras: mid-century ranches next to '80s and '90s development next to new builds. Heavy tree cover throughout means branch impact, debris in valleys, and moss on the shaded northern slopes.

North Hills

Ross Township, McCandless, Shaler, Hampton, West View, Bellevue, Avalon, Wexford, Franklin Park, Pine.

Two distinct patterns up here. The river boroughs — Bellevue, Avalon, West View — are older and tighter, with compact lots and the same aging chimney-and-flashing issues as the city. Head north toward Wexford, Franklin Park, and Pine and the housing is largely postwar through recent, with bigger footprints, multiple roof planes, attached garages, and skylights.

Newer isn't automatically better. Volume-built roofs from the 1990s and 2000s are hitting the age where the original asphalt is genuinely done, and installation shortcuts from that era — thin flashing, poorly cut valleys — show up right about now.

West suburbs

Moon Township, Robinson, Coraopolis, Carnegie, Crafton, Oakdale, Kennedy, Sewickley, Findlay.

The airport corridor picked up substantial development from the 1980s on, so out here you'll see conventional asphalt on straightforward roof geometry more often than not. Carnegie, Crafton, and Coraopolis are older river-valley boroughs with the mixed housing and drainage complications that go with hillside lots. Sewickley runs to large, architecturally involved homes, some with slate or tile.

Open exposure on the ridges west of the city means wind is a bigger factor than it is in a sheltered East End street grid. Lifted shingles and torn ridge caps after a big storm are common.

Beaver, Butler, and Washington County edges

Cranberry, Mars, Zelienople, Aliquippa, Ambridge, Canonsburg, McMurray, Bridgeville, Peters Township.

We do get requests from outside Allegheny County and can often help. There's no line on a map that makes it automatic, though — it comes down to whether a given contractor's route reaches you. Call with the municipality and ZIP and you'll get a straight yes or no rather than a maybe.

What to have ready when you call

• Your municipality and ZIP — not just "Pittsburgh," since that could mean fifteen different drive times.
• What the roof is, if you know. Asphalt, slate, tile, metal, flat or low-slope.
• What's happening and when it started. "Stain in the back bedroom ceiling, showed up after the storm two weeks ago, gets bigger when it rains hard."
• Whether water is coming in right now. That changes the urgency.
• Anything you've already had done up there.
