The Last Roof You’ll Think About
Metal Punishes
Sloppy Work
A metal roof is the one you put on when you’re done thinking about roofs. Done right, it outlasts two or three shingle roofs, shrugs off wind and snow, and keeps your house cooler in the summer. Garrison Roofing installs and repairs metal roofing across Philadelphia and the surrounding areas, on modern homes, historic rowhomes, and light commercial buildings alike.
We’ve been at this for over 20 years, with in-house crews and no subcontractors. Metal punishes sloppy work, because a bad seam or a wrong fastener will leak. So the crew that measures your roof is the crew that installs it, and we stand behind every panel we put down.
Not All Metal Is The Same
Metal Roofing Systems
We Install
Not all metal roofs are the same. The right system depends on your building, your budget, and the look you’re after. These are the ones we work with most:
01
Standing Seam
The premium choice — raised, interlocking seams that hide every fastener and leave nothing exposed to the weather. Clean lines, decades of life.
02
Copper Roofing
The top of the range. Ages into a distinctive patina and can last a century, which is why it shows up on historic homes, bay windows, and architectural accents.
03
Galvanized Steel
A tough, cost-effective option — zinc-coated to resist rust and hold up to Philadelphia weather year after year.
04
Corrugated Panels
Ribbed panels that go up efficiently and perform well on light commercial buildings, garages, and porches.
05
Metal Roof Capping
Aluminum and copper along the fascia, trim, and roofline to seal out water. See capping →
One Roof Instead Of Three
Why a Metal
Roof Lasts
The reason people go metal is simple: it lasts. A quality metal roof can run 50 years or more, and a copper roof can outlive the person who paid for it. Compared to a shingle roof you’ll replace every 20-some years, that’s one roof instead of two or three.
Metal earns that life because it doesn’t do the things that kill other roofs. It won’t rot or grow moss, and fire doesn’t touch it. Snow and ice slide off instead of piling up. Wind that peels shingles has nothing loose to grab, and on a standing seam roof the fasteners are hidden under the seams, so there’s no exposed hardware waiting to fail.
The catch is the install: all of that only holds if the seams are locked right and the panels are fastened to allow for the way metal expands and contracts with temperature. That’s where an in-house crew with 20-plus years on Philadelphia roofs earns its keep.
Working While It’s Up There
Cooler in Summer,
Lower Bills
Metal works for you while it’s up there. It reflects a good share of the sun’s heat instead of soaking it up the way dark asphalt does, so your attic runs cooler and your air conditioning doesn’t fight as hard in July. Over the life of the roof, that adds up on your energy bills, one reason homeowners who’ve had a metal roof rarely go back to shingles.
Historic Homes
The Original Roof On A Lot Of These
Metal for Historic
Philadelphia Homes
Philadelphia is full of older homes and historic rowhomes, and metal has a long history on them. Standing seam and copper were the original roofs on a lot of these buildings, and on the right home they still look like they belong.
Garrison has real experience on historic Philadelphia rowhomes and older properties, and it matters more than people realize. These roofs have quirks, tight tie-ins to neighbors, decorative metal, flashing details a modern crew might not know how to handle. Copper on a bay window or a rowhome cornice isn’t a job you hand to whoever’s cheapest. It’s detail work, and we treat it that way.
Metal isn’t only for historic homes. Corrugated and standing seam panels are a workhorse on light commercial buildings, garages, and porches, so whether you want a home roof you’ll never think about again or you own a building and are tired of patching, it’s worth a look. If your building has flat sections too, we handle those on our Flat Roofs page.

Cost Per Year, Not Sticker
What a Metal Roof Costs
Metal costs more up front than shingles, and we won’t pretend otherwise. What you’re buying is a roof that can last two or three times as long — so the real comparison isn’t the sticker, it’s the cost per year on the roof. Over the life of the building, metal often comes out ahead.
Every roof is different, so an honest number means someone actually measuring yours. What we can promise: the estimate is free, it’s itemized, and there’s no obligation.

Straight Answers
Frequently Asked Questions
How long does a standing seam metal roof last?
A properly installed standing seam metal roof can last 50 years or more — two to three times the life of a typical asphalt shingle roof. The hidden fasteners and interlocking seams are a big reason why, and it has to be installed right to reach that lifespan.
Is copper roofing worth the cost on a historic Philadelphia home?
On the right home, often yes. Copper can last a century and ages into a patina that suits older architecture, so on a rowhome cornice or a home where the roof is part of the character, it’s usually a once-and-done investment. We’ll give you a straight opinion on whether it makes sense for yours.
Can metal roofing be installed over an existing roof?
Sometimes. Metal is light enough that it can occasionally go over an existing layer if the structure and code allow it — but if there’s moisture or rot in the deck, covering it over just traps the problem. We’ll inspect it first and tell you honestly whether you can go over the top or whether a tear-off is smarter.
How does metal roofing handle Philadelphia winters?
Well. Snow and ice slide off instead of piling up, and metal doesn’t crack or get brittle in the cold the way some materials do. The key is proper flashing and fastening that lets the metal expand and contract as temperatures swing.
