The best way to compare metal roofing contractors in Pittsburgh is to ask five things: which panel system they are quoting (standing seam or exposed fastener), what gauge and coating the metal carries, how they handle snow retention, how many metal roofs they installed in the last two years with local addresses you can drive past, and whether the quote includes a written manufacturer warranty on the paint finish. Installed metal roofing in the greater Pittsburgh area runs $500 to $1,600 per square as of September 2026, with panel type and crew experience driving most of that spread.
We have installed asphalt since 1995 and added metal because Westmoreland County customers kept asking. A metal roof done right outlasts two asphalt roofs here. Done wrong, it leaks at every screw by year ten. Here is how to tell which one you are being quoted.
What is the difference between standing seam and exposed fastener metal roofing?
Standing seam panels lock together at raised vertical seams, with the clips hidden under the seam. No screws go through the face, and the panels can expand and contract with our temperature swings, which can be 100 degrees between January and July. This is the system we recommend on a house.
Exposed fastener panels, sold as ag panel, R panel, or corrugated, are screwed straight through the face. Each rubber washer dries out, and panel movement wallows the holes. On a barn it is fine and cheap. On a heated house in a Pittsburgh freeze thaw cycle, leaks start between years 8 and 15 unless every screw is replaced. Some contractors quote exposed fastener on houses without saying so. Ask.
What gauge and coating should a metal roof have in Western PA?
Gauge is thickness, and a lower number is thicker. Residential standing seam should be 24 gauge steel, or 26 at the lightest. Exposed fastener panels are commonly 29 gauge, thin enough to dent under hail. Aluminum at .032 inch is a good choice for zero rust risk. The coating matters as much as the metal. Steel should be Galvalume base with a PVDF paint finish, sold under names like Kynar 500, which holds color and resists chalking for 30 years or more and carries a written finish warranty from the coil maker. The cheaper SMP finish is fine on a barn but fades faster on a south facing slope.
Why does snow retention matter on a Pittsburgh metal roof?
Metal is slick, and a slope of wet March snow releases all at once, taking the gutters with it and burying the front walk. Snow retention means clamp on guards or a snow rail above the eaves, entries, and anywhere the roof drains onto a lower roof or walkway. A good quote calls out snow retention by location and quantity. A quote that skips it is either incomplete or the contractor has not worked a Western Pennsylvania winter with metal.
What questions should I ask any metal roofer in Pittsburgh?
Ask how many metal roofs they installed in the last two years and for five addresses within 30 minutes of Irwin. Drive past them and look at the seams, the eave line, and how the panels meet the chimney. Ask who forms the panels, because horizontal end laps on a residential slope are a red flag. Ask what goes under the metal: the right answer is high temperature ice and water shield at eaves and valleys and high temperature synthetic underlayment everywhere else. Ask about ridge ventilation. And ask for the finish warranty, the workmanship warranty, and the PA Home Improvement Contractor number in writing. Our guide on how to choose a Pittsburgh roofer covers the rest, and our post on licensed roofing contractors in Pennsylvania shows how to verify the license.
What certifications and experience matter for metal roofing?
Metal is less about a badge and more about hours on the brake. No single metal certification carries the weight Owens Corning Platinum carries in asphalt. Some panel manufacturers run installer programs, and the National Roofing Contractors Association publishes the metal roofing manual a serious installer keeps on the shelf. Some local companies focus on metal exclusively, and that depth is a real strength if standing seam is all you need. The trade off is that a metal only shop usually cannot handle the gutters, siding, and trim a roof replacement touches, while a full exterior contractor with an experienced metal crew carries all of it under one permit and one warranty.
How much does metal roofing cost in Pittsburgh?
Last updated September 2026. Installed pricing in the greater Pittsburgh area, including tear off, underlayment, trim, and disposal: exposed fastener steel runs $500 to $900 per square, metal shingles and stone coated steel $800 to $1,300, and standing seam steel with a PVDF finish $900 to $1,600. A square is 100 square feet. For a typical 25 square home in North Huntingdon or Monroeville, that is $22,000 to $40,000 for standing seam versus $12,000 to $20,000 for architectural asphalt. What moves the price: roof complexity, gauge and finish, snow retention, and decking repairs once the old roof is off. Compare any metal bid against our roof replacement cost guide.
In our Westmoreland County jobs, the rule of thumb we give homeowners is that standing seam costs about twice what architectural asphalt costs on the same roof and lasts about twice as long, so the decision comes down to how long you plan to own the house.

How does Bella handle metal roofing alongside asphalt?
We are an asphalt company first. Owens Corning Platinum Preferred is a badge fewer than 1 percent of roofers hold, and most roofs we install in Irwin, Norwin, Greensburg, and the South Hills carry the Platinum warranty. We added standing seam because homeowners asked and because crews that flash a chimney well in asphalt flash one well in metal.
When you call us about metal, you get both bids on the same visit, priced on the same roof with the same tear off, decking allowance, and gutter work. We will tell you honestly if your roof is a better fit for asphalt, which is often true on complex roofs where standing seam labor climbs fast. Because we handle gutters, siding, and windows, the trim details get done by one crew under one warranty. Our financing options cover metal at the same terms as asphalt.
Frequently Asked Questions
How much does a metal roof cost in Pittsburgh?
As of September 2026, installed standing seam runs $900 to $1,600 per square in the greater Pittsburgh area, or $22,000 to $40,000 on a typical 25 square home. Exposed fastener panels run $500 to $900 per square but suit barns and garages better than houses.
Is standing seam worth the extra cost over exposed fastener panels?
On a house, yes. Standing seam hides every fastener, lets the panels move without wallowing screw holes, and carries a 40 to 60 year life here. Exposed fastener panels need every screw replaced around year 10 to 15 and are more likely to leak on a heated home in our freeze thaw climate.
Does a metal roof need snow guards in Pennsylvania?
Yes on any slope that drains over a walkway, entry, gutter, or lower roof. Metal releases snow in a single sheet, and a March slide can take gutters off the house. Guards or a snow rail above those areas belong in every quote.
Can a metal roof be installed over asphalt shingles?
Code allows it over a single flat layer in Pennsylvania, but we recommend a tear off so the decking can be inspected and high temperature underlayment can go down. A roof over saves a little on disposal and costs you the chance to find rot before it leaks under a 50 year roof.
If you are weighing metal against asphalt anywhere in Westmoreland County, Allegheny County, or greater Pittsburgh, we will measure your roof for free and give you both numbers side by side.
