Roof Replacement Boise is a roofing company serving Boise and the Treasure Valley, and commercial roof replacement 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 roof survey and a written per-square price broken out for material, tear-off, and any deck repair
Full tear-off to the deck on re-roofs, or a fully documented recover assessment when code and roof condition allow it
TPO, EPDM, or metal systems installed to the scope your building actually needs — flat, low-slope, or steep
Phased scheduling built around tenant, retail, or office hours to minimize business disruption
Rooftop equipment, HVAC curbs, and penetrations flashed and re-sealed to spec, not just caulked over
Coordination with property managers or ownership on access, parking, and tenant notice
City permit pulled for the job before work starts
Full site cleanup and haul-away, with a magnet sweep of parking areas and walkways

What this costs in Boise

Commercial Roof Replacement runs $550–$950 per roofing square installed in this area. Based on TPO/EPDM low-slope pricing, the system used on most Boise-area commercial buildings; steep-slope commercial roofs (some churches, mixed-use buildings) are priced per the applicable shingle or metal material band, not this range.. 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.

When it needs doing

Ponding water on a flat or low-slope roof more than 48 hours after rain
Membrane seams lifting, blistering, or visibly separating
Leaks appearing near rooftop HVAC units or other equipment curbs
Interior ceiling stains in retail, office, or common areas
Visible wear or granule loss on steep-slope sections of a mixed building
Original roof dates to the 1990s–2000s building boom and is past typical service life

How it works

How commercial roof replacement runs

01
Roof survey and scope
We walk the roof (or roofs, for multi-building properties), check drainage and membrane or shingle condition, and hand you a written per-square price broken out by system.
02
Permit and phased plan
We pull the required city permit and build a phased schedule around your tenants' or customers' hours, so the property stays open while work happens overhead.
03
Tear-off and install
Crews sized to the job install the new low-slope membrane or steep-slope system section by section, flashing rooftop equipment and penetrations as we go.
04
Inspection and handoff
Final inspection, cleanup of all work areas including parking and walkways, and a walkthrough with your property manager or ownership group before we close out the permit.

Questions

Commercial Roof Replacement questions

How long does a commercial roof replacement take?

Timeline depends on square footage, number of buildings, and whether it's a single low-slope roof or a mix of flat and steep-slope sections. A single retail building or small office can often finish within a week once material is on-site; larger multi-family or multi-building properties are typically phased over several weeks so the property stays occupied and operating the whole time.

Can you replace the roof without shutting the building down?

In most cases, yes. Flat roof tear-off and install happens entirely from the roof, and we sequence the work to keep noise and disruption to the interior minimal. We'll walk through the specific timeline and any access needs for your building at the inspection.

Do you install both flat and steep-slope commercial roofing?

Yes. Most commercial buildings in the valley are low-slope and get a TPO or EPDM membrane, but some mixed-use, church, or steep-roofline buildings need a shingle or metal system instead. We scope and price whichever your building actually has.

Is a permit required for a commercial re-roof in Boise?

Yes — commercial re-roofing requires a city building permit just like residential work, and the fee is based on the valuation of the job. We pull it before work starts so it's never something you have to track down yourself.

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.
