Metal Roofing Boise is a roofing company serving Boise and the Treasure Valley, and steel roofing is one of the services we handle most. This page covers what the work involves here specifically — the climate, the code, and what it costs — rather than what it involves in general.

What we do on the first visit

The first visit is an inspection, not a sales call. We walk the roof with you, check the deck from the attic side where we can, count valleys and penetrations, and note the pitch and how much staging or safety equipment the job needs. We confirm whether any prior layers are on the roof already — code allows a maximum of two before a full tear-off is required — and then you get a written per-square price with tear-off and any deck repair as separate lines.

If we think repair is the better spend than replacement, or a different material suits your situation better, we say so on that visit — including when it means the smaller job for us.

What's included

On-site inspection and a written per-square price before any work starts
Steel panel system selection — standing seam or exposed-fastener — matched to budget and roofline
Galvalume AZ50 or G90 galvanized coil coating, with Kynar 500/PVDF finish options
Fastening system engineered for Boise's thermal swing, floating clip or manufacturer-spec through-fastened
High-temperature synthetic underlayment and ice-and-water membrane where needed
Custom-fabricated flashing and trim
Attention to galvanic corrosion risk where steel panels meet dissimilar metal (copper gutters, etc.)
Full site cleanup and haul-away

What this costs in Boise

Steel Roofing runs $800–$1,600 per roofing square installed in this area. 2026 published national installed pricing for steel panel systems ($10-16/sq ft standing seam, $7-12/sq ft exposed-fastener, HomeGuide), depending on panel system chosen. The things that move a job up its range are tear-off, how much deck repair is needed, pitch, and how many valleys and penetrations your roof has. If you want a number before you call, the roof cost calculator will get you close.

Questions

Steel Roofing questions

Is steel or aluminum better for a Boise roof?

Steel is the more common and typically more economical choice here, and Boise's inland, low-humidity climate doesn't demand aluminum's coastal corrosion resistance the way a marine environment would. Aluminum is worth considering mainly for weight-sensitive applications or specific finish preferences — see our steel vs. aluminum guide.

Will my steel roof rust?

Not under normal conditions with a proper Galvalume or galvanized coating — but lower-grade galvanized panels can show premature edge corrosion where something like sprinkler overspray regularly mists a lower roof or valley. We spec Galvalume or better specifically to avoid that.

What gauge steel should I use?

24-26 gauge is standard for standing seam residential work; exposed-fastener panels commonly run 26-29 gauge. Heavier gauge costs more but resists oil-canning and denting better — we'll recommend the right gauge for your roof and budget at the inspection.

Does a steel roof lower my homeowners insurance?

Some Idaho insurers offer a discount, particularly for Class 4 impact-rated steel panels — it varies by carrier, so it's worth asking yours directly. See our insurance guide for what to ask.

Do you charge for an estimate?

No. Estimates are free across Boise and the Treasure Valley, including the drive. We walk the roof with you, check the deck from the attic side where we can, and hand you a written per-square price with tear-off and any deck repair broken out as their own lines.
