Why seamless steel fits the Front Range

Siding here has a hard job. Summer storms bring hail, chinook winds gust past 80 miles an hour, a sunny day can drop forty degrees by nightfall, and heavy spring snow melts down every wall. Vinyl turns brittle in a cold snap and cracks when it's hit, and wood needs scraping, staining and painting every few summers to stay ahead of the weather.

Heavy-gauge G-90 galvanized steel holds its shape through every swing in temperature and stands up to impacts that crack plastic panels. The finish is guaranteed never to flake, peel or chip, so there's nothing to repaint. And because every piece runs the full length of the wall, there are no overlapping joints for wind-driven snow, water or insects to get behind.

What "seamless" actually means

Most siding is made in a factory in 12-foot pieces, so a long wall ends up with joints on every row. We bring the forming machine to your driveway and roll each piece from a coil of steel at the exact length of your wall.

What a correct install includes

We start by measuring every wall and opening and looking at what's underneath the old siding. On install day the old material comes off, the walls are checked, and each course is formed and hung in one continuous piece. Corners, windows and doors get matching steel trim, and soffit and fascia are screwed in place rather than stapled so they hold through chinook wind.

Choosing a profile and color

Lap and Dutch lap give a classic horizontal look. Board & batten reads mountain modern, especially in darker colors. Steel log siding gives you the look of a log home without the staining and re-chinking. See any of them at our Fort Collins showroom, or we'll bring real samples to your kitchen table.

Steel siding, answered.

How much does steel siding cost in Fort Collins?

It depends on the size of the house, the number of openings and the profile you choose. We measure every wall in person and leave you a written, itemized price. The visit is free and there's no obligation.

Is steel siding better than vinyl on the Front Range?

For most homes here, yes. Vinyl gets brittle in a hard cold snap and cracks when it's hit by hail or a stray rock. 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.

Will steel siding dent in a hailstorm?

Heavy-gauge steel stands up to hail far better than vinyl, which can crack or shatter. Very large hail can mark any exterior material, so we'll show you real samples and walk through the gauge and warranty at your estimate.

What profiles and colors can I choose?

Lap, Dutch lap, board & batten, vertical and steel log, in a full range of colors. We bring real samples to the visit, or you can see every color at our Fort Collins showroom.

Can you match my gutters, soffit and fascia?

Yes. We install seamless gutters and steel soffit and fascia in matching colors, so the whole exterior is done by one crew under one warranty.
