Standing Seam Metal Roofing for Western Montana Homes

Snow shedding: plan where it lands

A slick metal roof can drop a winter's worth of snow in one slide. That's great for the roof and hard on whatever is below it. Before we quote a metal roof, we walk the house with you and look at:

• Entry doors, decks, and walkways under the eaves.
• Driveways, parked cars, and garage doors.
• Gas meters, propane tanks, heat-pump units, and vent pipes.
• Lower roofs, gutters, and windows that a slide could hit.

Where a slide would cause harm, snow guards or snow-retention bars hold the snow so it melts off gradually. Vent pipes can get diverters so sliding snow doesn't shear them off. On very cold, shaded roofs snow may not slide for a long time, so we still install ice and water protection at the eaves.

Wildfire resistance

In the wildland-urban interface, which covers a large share of western Montana, homes usually catch from embers rather than a wall of flame. Standing seam steel panels don't burn, and metal roofing systems can achieve Class A fire ratings when installed over approved underlayment. Because the fasteners are hidden and the seams interlock, there are fewer openings on the roof face. We also close the gaps at ridges and eaves with metal closures, look at ember-resistant vent options, and recommend gutter details that are easy to keep free of needles.

Longevity, done right

Metal lasts when the details are right: the correct underlayment for condensation, fasteners and clips spaced for snow and wind, sealed trim at every edge, and flashing that lets panels move. Most metal roof problems we're called to fix trace back to one of those details, not the metal itself.

Metal over shingles, where code allows

A metal roof can sometimes go over an existing shingle roof without a tear-off. Building codes generally allow it only when there's a single existing layer and the deck and shingles are sound and dry, and the local building official has the final word. When it's allowed and the roof checks out, we install a proper underlayment, and often a furring grid, before the panels. If we find soft decking, more than one layer, or trapped moisture, we'll recommend a tear-off instead and show you why.

Budget-friendly exposed-fastener metal for shops, outbuildings, and cabins

Not every roof needs standing seam. For a shop, barn, garage, or simple cabin, or a home where the budget comes first, exposed-fastener (screw-down) metal is a durable, lower-cost option. We also repair aging screw-down roofs: replacing worn screws, sealing laps, and replacing rusted panels. We can look at your outbuildings during the same free inspection as your house.
