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](https://arproofing.com/residential-roofing/metal-roofing/) 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. The Metal Roof ## The Metal Roof Install, Step by Step 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](https://arproofing.com/residential-roofing/metal-roofing/snap-lock-vs-double-lock/). 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. ![Standing seam metal panels being installed on a residential roof](https://arproofing.com/_astro/metal-standing-seam-roof-installation-residential.Bl4spRSH_1hGQTf.webp) The panels go on with concealed fasteners and the flashing is detailed at every valley and penetration, which is where a metal roof lives or leaks. On-Site Roll-Forming ## On-Site Roll-Forming, and Why It Matters 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](https://arproofing.com/residential-roofing/metal-roofing/standing-seam-panel-profiles/) gets made.

How Long Does ## How Long Does a Metal Roof Take to Install in Texas? 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. ![Roofing crew setting metal roofing panels during a residential install](https://arproofing.com/_astro/metal-roofing-panel-installation-crew.EkNsIsBS_Z1sbobv.webp) Most Texas homes take three to five days, a couple of days longer than shingles, because the seam and flashing work sets the pace. Change Orders Handled ## Change Orders, Handled Honestly 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. ![Randal Williams, ARP Roofing COO & Senior Roofing Consultant](https://arproofing.com/_astro/arp-roofing-randal-williams.XIeD7i6f_1Tjv4T.webp) > We give you a written scope before we start.

A metal roof is installed in seven steps: free inspection, written estimate, tear-off and deck check, synthetic underlayment, on-site roll-forming of the panels, panel and flashing install with concealed fasteners, and a final inspection with your warranty registered. The flashing and seam details are what make the roof last. ### How long does it take to install a metal roof? Most metal roofs take three to five days 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 and roof complexity move the timeline, and we give you a real schedule before we start. ### Can a metal roof go over an existing roof? Sometimes, but we usually don't recommend it for a roof meant to last 40 years. Installing over old shingles can trap heat and moisture and hides deck problems you'd want caught. On a standing seam install we tear off, inspect and photograph the deck, and build the roof on a sound, documented foundation. ### Do I need to leave my house during a metal roof install? No. You can stay home during a metal roof install. There's noise during tear-off and install, and a metal roof is a bit louder to build than shingles, but you don't need to move out. We protect your landscaping, keep the site clean daily, and let you know the schedule so you can plan around the loudest days. ## Start with the assessment, not the estimate We look at the roof, document what we find with photographs, and give you the written assessment — whether or not you hire us. Then you decide, on your timeline.
