How Long Does It Take to Replace a Roof?

The short answer

A typical single-family home in Minot, somewhere between 1,800 and 2,600 square feet of roof surface, takes one to two days for a full tear-off and replacement. A crew of five to seven starts around 7am and the house is watertight before they leave on day one, every time.

Larger, steeper or more cut-up roofs run three to four days. Standing seam metal runs three to five. A commercial low-slope system is a different animal and gets scheduled in sections.

What actually happens, hour by hour

Day one, 7:00am to 9:00am: setup and tear-off begins

Dump trailer positioned in the driveway. Tarps over landscaping, plywood against the siding where debris will land. Then tear-off starts at the far side of the roof and works back toward the trailer.

Day one, 9:00am to 1:00pm: tear-off and deck inspection

This is the loud part. Every existing layer comes off down to bare wood. As sections open up we walk the deck looking for soft spots, delamination and rot, usually around chimneys, valleys and anywhere a previous leak was patched instead of fixed. Anything bad gets photographed and you get a message before it is replaced.

Day one, 1:00pm to close: dry-in

Ice and water shield at the eaves, valleys and every penetration. Synthetic underlayment across the rest of the deck. Drip edge on. The house is now watertight. Even if a thunderstorm rolls in overnight, nothing gets in.

This is the single most important scheduling promise a roofer makes. Ask any contractor directly: will my house be dried in before you leave on the first day? If the answer is anything other than yes, keep looking.

Day two: shingles, flashing, ventilation, cleanup

Starter course at eaves and rakes, then field shingles up to the ridge. New pipe boots and step flashing, not reused. Ridge vent installed. Then cleanup: debris hauled, and a magnetic sweep over the entire yard, driveway and street for nails.

Five things that add days

Factor	Time added	Why
A second or third existing layer	+half to one day	Double the tear-off labor and dump weight
Steep pitch, above 7/12	+30 to 50%	Fall protection staging, crew moves slower
Extensive deck replacement	+half to one day	Cannot be known until the roof is open
Cut-up roof, many valleys and dormers	+one day	Custom flashing on every intersection
Weather	Varies	We do not tear off into rain, and asphalt needs hand-sealing below 40 F

What you need to do

• Clear the driveway so the dump trailer can get close. If it cannot, everything moves by hand and the job takes longer.
• Move vehicles off the street near the house.
• Take pictures off the walls in rooms directly under the roof. Vibration knocks frames down more often than people expect.
• Cover things in the attic, or at least anything you care about. Tear-off drops dust and old nail debris between the rafters.
• Plan for the dog. It is loud for eight hours.

You do not need to be home. Most of our customers go to work and come back to a finished roof.

Why the calendar wait is longer than the job

The work is two days. Getting on the schedule is usually two to six weeks in the summer, longer after a hail event when everyone in Ward County is calling at once. If you know your roof is coming due, get on a schedule in spring rather than reacting to a leak in October.

Emergencies do not wait for the queue. An active leak gets a tarp within a day.
