Why Clark Fork
Neighbors trust us, and say so.
“We had a 1970s ranch with vinyl that cracked every winter. Kate came out herself, measured every wall and laid real steel panels against the house so we could see the color in daylight. The crew finished in four days, cleaned up every evening and walked the whole job with us at the end. It looks like a brand-new house.”


We stand behind our work

From the first call to the last panel
A Missoula family,
not a call center
My dad, Walt, started Clark Fork out of a one-truck garage in 1984. Today it is twenty-two of us: estimators, installers and the folks who answer your call. We still measure every job ourselves and we still drive past the houses we sided thirty years ago.

Our reviews speak for themselves
4.9 average from 312 verified Google reviews across Western Montana.
Kate and her crew re-sided our whole house in four days. The gutters were formed right in the driveway. Not a single seam, not a single drip this fall.
Three companies quoted us. Clark Fork was the only one who measured every window and showed us real panels against the house. Easy choice.
Our standing seam roof went on in three days. They tarped the flower beds and ran a magnet for nails twice. Five stars.
Hail took out our neighbor’s vinyl in July. Our steel siding from Clark Fork didn’t get a mark.

What do you need?
Good to know before you call.
Is steel siding better than vinyl in Montana?
For most homes here, yes. Vinyl gets brittle in deep cold and can crack when it's hit by hail or a stray rock. Our heavy-gauge G-90 galvanized steel holds up to both, has no seams for snow and water to get behind, and carries a finish guaranteed never to flake, peel or chip.
What does "seamless" actually mean?
Most siding and gutters come in fixed lengths that get overlapped at the joints. We bring the forming machine to your home and roll each piece from steel coil at the full length of the wall or roofline, so there are no seams where moisture, dirt or insects can collect.
Can you do siding, roofing and gutters together?
Yes, and it's usually the best value: one estimate, one crew, colors that match across siding, trim, soffit, gutters and roof, and one warranty from one local company.
Do you install steel log siding?
We do. It's popular around Kalispell and the Flathead with homeowners who love the log-home look but are done with staining and chinking.
What does the lifetime warranty cover?
Our seamless steel siding, gutters, and soffit and fascia carry a lifetime warranty. We'll walk you through exactly what's covered for your project at the estimate and give it to you in writing.
