Your insurance claim got approved last week. Contract's signed. The crew shows up Monday morning. You're relieved things are moving forward, but you're also staring at your calendar wondering what the next few days actually look like. How loud does this get? What about your yard? And seriously—what happens if it starts pouring halfway through?
Here's the real timeline of a roof replacement in Oklahoma, from the day the trucks pull up to the moment you get your final invoice.
The Week Before: Logistics Nobody Tells You About
Three or four days out, you'll get a call from the project manager. They'll confirm the start date and ask about obstacles—trampoline in the back, cars that need moving, dogs that panic at loud noises. This isn't small talk. The crew needs clear access around your entire house, and sorting this out now keeps the project from stalling on day one.
Materials show up a day or two before the crew does. Big semi-truck. Forty to sixty bundles of shingles stacked in your driveway, each one weighing about 75 pounds. The pile looks massive. That's normal. Covering 2,500 square feet of roof takes a lot of material.
The night before work starts, move your cars. Pull patio furniture and grills away from the house. Take down anything fragile hanging on walls near the exterior—tear-off vibrations can knock pictures loose. Got stuff stored in your attic? Toss a tarp over it. Dust filters down through roof vents during demo.
Day One: The Loud Part
Crew rolls in around 7 or 8 a.m.
You'll hear them. Tear-off is brutal. Flat shovels, pry bars, everything ripped down to bare wood. It all goes into a dump trailer parked somewhere near your driveway. The noise doesn't let up for the first few hours. That's just how it goes.
Once the old shingles are off, they inspect the decking. This is when you find out if you've got damaged plywood hiding under there. Oklahoma's weather beats the hell out of roof decks over time. Hail cracks the sheathing. Wind-driven rain soaks into gaps where shingles lifted. If your adjuster already included deck replacement in the estimate, this is when it happens. If they didn't—and the crew finds rot or damage—somebody's calling you about additional cost.
Deck replacement slows things down. Half a day, full day, depends how much needs replacing. They cut out the bad sections and install new OSB or plywood, usually 7/16-inch or 1/2-inch thickness, nailed down with ring-shanks spaced to code. Oklahoma follows the International Residential Code, according to the Oklahoma Uniform Building Code Commission, though some local jurisdictions tighten fastening requirements in high-wind areas.
Building It Back: Layer by Layer
After deck repairs, they start rebuilding. Drip edge goes along the eaves first—metal flashing that keeps water off your fascia boards. Then underlayment rolls out across the whole deck. Most crews use synthetic now instead of old-school felt. Handles UV exposure better if the project stretches over multiple days. Doesn't wrinkle when it gets wet.
Ice and water shield goes in the valleys and along the bottom edges. Self-sealing membrane that stops water infiltration where your roof's most vulnerable—during freeze-thaw cycles, ice dams, all that. Valley protection matters here. Those channels funnel serious water volume during storms.
Starter strips nail down along the edges. These seal the first course of shingles and keep wind from peeling up the edges. Then the field shingles go down, row by row, bottom to top. Each one gets four to six nails depending on what the manufacturer requires and what wind zone you're in. We're in a high-wind region here—sitting near the heart of tornado alley means proper fastening isn't negotiable, according to the National Weather Service.
Hip and ridge caps finish it off. Thicker than regular shingles, installed along the peaks and hips. These take the most wind abuse, so they get extra attention.
When Weather Crashes the Schedule
Oklahoma weather doesn't care about your project timeline.
Rain shows up mid-job? Crew tarps the exposed sections and waits it out. A properly tarped roof won't leak, but nobody wants that sitting there for three days. Most crews watch the forecast like hawks and won't start if rain's coming within 48 hours.
Spring's the worst for delays. Storm systems roll through every few days. Summer heat slows things down too—shingles get dangerously hot when your roof deck hits 150 or 160 degrees. Crews start earlier and knock off earlier in July and August just to stay safe.
Wrapping Up: Cleanup and Final Walkthrough
Last shingle nailed? The crew walks your property with magnetic rollers. Picking up stray nails from the driveway, yard, flower beds. They'll go over the same spots multiple times because one nail in your tire costs them their reputation.
Project manager does a final inspection before they leave. Walks the roof, checks flashing, verifies sealant around pipes and vents, makes sure every course lines up straight. You can walk it with them if you want, though most people are fine viewing from the ground.
Dump trailer gets hauled off. Materials loaded up. Site cleared. What you've got left is a clean yard and a roof that should handle Oklahoma weather for the next 15-20 years, assuming you keep up with basic maintenance.
Most residential replacements around Oklahoma City take two or three days start to finish. Bigger homes, complicated rooflines with multiple valleys and dormers, projects needing major deck work—those stretch to four or five days. Weather delays add time. But the sequence stays the same no matter how long it takes.
