Most building owners plan their commercial roof installation around a guess, and that guess usually costs them. Production on a commercial re-roof follows a measurable daily rate, and the total schedule comes down to the size of your roof and what sits on top of it.
At Precision Roofing, we track our crews’ footage every day, so you get a realistic start date and finish window before the first truck pulls onto your property.
How Long a Commercial Roof Installation Really Takes
On a standard commercial re-roof, our crews average around 5,000 square feet per day. That number covers the full process, from tearing off the existing membrane and insulation down to the deck to installing the new system in its place.
Fifty squares per day gives you a dependable starting point for planning. A 40,000 square foot warehouse, for example, falls into a range of roughly eight working days.
Our Average Daily Production
- Wide open roofs with few obstacles hit or exceed 5,000 square feet per day
- Roofs crowded with curbs, units, and pipes move at a slower pace
- Daily production includes both the tear-off and the new install on that section
Why Every Roof is a Case-by-Case Job
Restaurants are the clearest example. Exhaust units, grease ducts, vents, and other penetrations force our crews to slow down and detail every protrusion correctly. That detail work protects you from leaks later, and it takes time.
What you tear off and what you go back with also shift the math. Every building deserves its own estimate rather than a generic timeline.
Key Takeaway: Ask what sits on your roof before you ask how long the job will take. Penetrations, not square footage alone, drive the schedule.
What a Full Tear Off Includes
Removing the Existing System
We strip the old membrane and insulation all the way down to the deck. Working down to bare deck lets us inspect the substrate, confirm its condition, and catch problems that a recover job would hide.
Installing New Insulation and Membrane
New insulation goes down first, followed by the new membrane and all associated details. Doing everything in one pass, rather than layering over old material, is what gives your building a full service life instead of a patched one.
Pro Tip: Schedule tear-off sections your crew can dry in the same day. We plan our daily footage around what we can close up before the workday ends.

Lead Times and Emergency Service
Scheduling Your Commercial Roof Installation
Our lead times vary with the season and our current backlog. Most of the year, we book anywhere from 6 to 12 weeks out.
Planning ahead gives you the widest choice of start dates. Owners who call us during their budgeting season almost always land the window they want.
Storm Damage and Next Day Response
Emergencies do not wait for a spot on the calendar. If a storm tears open a section of your roof tonight, we send a crew out the very next day to get it patched.
That temporary repair holds the building until we install the permanent system. It keeps water out, protects your insulation from saturating, and spares you weeks of ongoing damage while you wait for the full replacement.
Key Takeaway: A booked calendar never means you are on your own. Emergency patching happens first, and the permanent roof follows.
