Metal Roof Installation Process in Texas: What to Expect

See what a metal roof costs →

A metal roof is installed by tearing off the old roof, inspecting and repairing the deck, laying synthetic underlayment, then setting and seaming the metal panels with careful flashing at valleys and penetrations. The best crews roll-form the panels on site into full lengths. It takes a few days, and the details at the seams and flashing are what make it last.

You want to know what you're signing up for with metal roofing in Texas before the crew shows up, so here's the whole thing.

Metal isn't harder than shingles, it's just less forgiving of shortcuts. The panels are precise, the flashing has to be exact, and the seams have to be run right. That's why the crew and the scope matter so much on metal. Below is the step-by-step, so you know what a good install looks like and can spot one that isn't.

Here's your simple path, from the first call to the day you forget about your roof.

1. Free inspection. We measure your roof, check the deck and pitch, and look at your flashing points. No deposit, no obligation.
2. Written estimate. You get a full scope in writing: panel gauge, finish, seam profile, flashing plan, permit, and price, usually within 24 to 48 hours.
3. Tear-off and deck check. We pull the old roof and inspect the deck. Any rotted decking is shown to you, with photos, before it goes in the price.
4. Synthetic underlayment. A high-temp synthetic underlayment goes down as the water barrier under the metal.
5. On-site roll-forming. For standing seam, we roll-form the panels on your driveway into single lengths that run ridge to eave, so there are no horizontal lap seams to leak. The seam itself closes one of two ways, compared in snap-lock vs. mechanical double-lock standing seam.
6. Panel and flashing install. The panels go on with concealed fasteners, and the flashing is detailed at every valley, sidewall, and penetration. This is where a roof lives or leaks.
7. Final inspection and warranty. We inspect the finished roof, clean up the site, and register your warranty in your name.

The crew on your roof works under the direct supervision of an ARP project manager who checks the work at the key stages, so the details above actually get done, not just promised.

This is the step that separates a roof that lasts from one that leaks early.

Roll-forming is running flat coil metal through a machine that shapes it into finished panels. Doing it on site, on your driveway, means the panels come out in single continuous lengths that run all the way from the ridge to the eave. No horizontal seams, no laps, nothing to leak partway down the roof. A contractor who orders pre-cut panels has to lap them together, and every lap is a future weak point. On-site roll-forming is a mark of a crew that does metal right, so it's worth asking about. The same machine also shapes the pan between the seams, so it's where your choice among the standing seam panel profiles gets made. For more on what goes wrong without it, read metal roof problems.

Most metal roofs take three to five days to install on a typical Texas home, a couple of days longer than shingles. Standing seam takes longer because the panels are roll-formed on site and the seams and flashing can't be rushed. Weather, roof size, and complexity move the timeline, and we give you a real schedule before we start.

A fair question, because you're living under it while it happens.

Metal takes a little longer than a shingle roof, and that's a feature, not a delay. The seaming, the flashing details, and the on-site roll-forming are exactly the parts you don't want a crew hurrying through. We give you a realistic timeline up front and keep you posted as it moves.

The part homeowners worry about most, handled honestly.

Sometimes tear-off finds real hidden damage, like rotted decking under an old leak. That's a legitimate change order, and we document every square foot of it with photos before a single new piece goes down. What isn't legitimate is a surprise on day three because someone wrote a vague scope on day one.

We give you a written scope before we start. If a contractor won't put it in writing before the job, that tells you everything you need to know about what happens after.
