Standing-Seam Metal Roof Replacement in Severna Park
Family-owned, GAF Factory-Certified roofers documenting 24-gauge standing-seam metal roof replacement, custom-bent trim, and a 40-70 year service life for Severna Park homeowners since 2005. Free 24-hour inspection with a full photo report — yours to keep either way.
Standing seam is roughly two to two-and-a-half times asphalt — and lasts two to three times as long
| System | Field rate, installed | Service life | What it is for |
|---|---|---|---|
| Architectural asphalt shingle | $620/SQ | 25–30 yrs | The default. Best cost per year for most Severna Park houses. |
| 24ga standing-seam metal | $1,337/SQ | 40–70 yrs | Low-slope sections, long clean runs, and houses you intend to keep. |
A “square” is 100 sq ft of roof area. Field rate covers tear-off, panel and underlayment; custom-bent ridge, hip and valley trim is quoted per linear foot, and standing seam also carries a permit and engineering-letter line that asphalt does not. Rates are the Baltimore-market retail list from our published price book — a ballpark, not a quote. The real number comes off a measurement.
When metal is the right call on a Severna Park house — and when it is not
Metal earns its premium in three situations, and we will tell you when yours is not one of them. Low-slope and porch roofs where asphalt was never really appropriate and has been failing on a cycle. Long, simple, uninterrupted runs — a standing-seam panel on a clean gable is fast and beautiful; the same panel on a roof broken up by six dormers, three valleys and a turret needs so much custom bending that the cost climbs faster than the benefit. And houses you intend to keep: at a 40–70 year service life, metal is the cheaper roof per year, but only if you are still there to collect that.
If you are planning to sell inside five years, or your roof is a complex multi-plane Severna Park roofline, architectural asphalt is usually the better financial decision and we will say so.
Snap-lock vs mechanically seamed
On pitches of 3/12 and steeper we install snap-lock standing seam — concealed clips, no exposed fasteners, nothing through the panel face to leak in ten years. Below 3/12, and on any run with real water dwell, it has to be a mechanically seamed panel: the seam is folded closed on site with a seaming machine. Anyone quoting snap-lock on a low-slope section is quoting the cheaper install, not the right one.
The parts of a metal quote people get caught by
- Exposed-fastener panel is not standing seam. Corrugated agricultural panel screwed through the face costs a fraction of standing seam and has hundreds of gasketed holes in it. Those gaskets are the roof's service life. If a quote is far below the range above, this is usually why.
- Thermal movement. A long metal panel grows and shrinks with temperature. Clips must allow it. Panels fastened as though they were static oil-can, and eventually tear at the fastener.
- Trim is where metal is won or lost. Ridge, hip, valley, rake and the wall transitions are custom-bent on site. This is the line item worth reading, and the one that separates a metal roof at twenty years from one that is being repaired at eight.
- Ice and snow retention. Metal sheds snow in slabs. Over a Severna Park entry, walkway or driveway, snow retention belongs in the scope.
- Salt air. Closer to tidal water, coating system and fastener metallurgy matter more than the panel gauge does.

How much does a metal roof cost in Severna Park, MD?
24-gauge standing-seam metal runs about $1,337 per square (100 sq ft) installed in Anne Arundel County, against about $620 per square for architectural asphalt — roughly two to two-and-a-half times the cost, for two to three times the service life. Custom-bent ridge, hip and valley trim is quoted per linear foot on top, and metal carries a permit and engineering-letter line that asphalt does not. Those are retail list rates from our published price book, not a quote; the real number comes off a measurement of your roof.
Is a metal roof worth it on a Severna Park home?
It depends on three things and we will tell you honestly where you land. Metal wins on low-slope and porch sections where asphalt has been failing on a cycle, on long simple roof runs, and on a house you plan to keep for fifteen-plus years. It is usually the wrong financial call if you are selling within five years, or if your roofline is broken up by many dormers, valleys and turrets — the custom bending on a complex roof costs more than the extra life is worth.
Will a metal roof lower my insurance or make my Severna Park roof more hail-resistant?
Metal does not dent-proof a roof: large hail can cosmetically dent a standing-seam panel, and some carriers write cosmetic-damage exclusions specifically for metal. What metal resists far better than asphalt is granule loss, mat fracture and wind uplift, which are the failures that actually end an asphalt roof's life. Some carriers do give a credit for an impact-rated roof — ask yours before you assume it.
Can you install metal over my existing Severna Park shingles?
We tear off. A metal panel over existing shingles traps heat and moisture against the decking, hides whatever the decking is actually doing, and means nobody has inspected the substrate that the new roof depends on. It is faster and cheaper on the day and it is not how we build a 50-year roof.
