## Price

$550-$950 roofing square (100 sq ft) installed. 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.

## 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

## Process

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.

## FAQ

**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.
