Why standing seam suits Lake Dallas
Lake Dallas has been a lake town since the late 1920s, when residents renamed the old railroad town of Garza after the new reservoir. Many of its homes are older than the subdivisions around it, and a lot of them sit close enough to Lewisville Lake to feel the wind. Standing seam fits here for a few reasons:
- Lake houses, where hidden fasteners and no granules hold up well to wind and humidity off the water when the edges are detailed for it.
- Older homes with additions, where one standing seam system can run over the original roof and the add-ons, and mechanically seamed panels can handle a lower-slope section.
- Porches, bays and entries on homes with a shingle main roof, where a standing seam accent adds a finished look.
- Owners who are tired of replacing shingles after hail. Standing seam doesn't crack, curl or lose granules.

Snap-lock or mechanically seamed?
| Snap-lock | Mechanically seamed | |
|---|---|---|
| How the seam closes | Panels snap together by hand | A seaming tool folds the seam closed along its length |
| Best on | Most steep-slope house roofs | Low-slope porches and wings, and very long runs |
| Look from the street | Clean, slim seam | Slightly heavier seam; same concealed fasteners |
More detail: snap-lock vs. mechanical lock. We use 24 or 26 gauge steel and never 29 gauge on a home (why). We don't publish prices because size, pitch, tear-off and detail work move them too much; our standing seam cost page explains what moves the number, and you get a written price for your roof.
Low slopes: where the seam choice really matters
Snap-lock panels are the right choice on most steep house roofs. On a closed-in porch, a back room or a long shed-roof addition with a gentle pitch, we switch to mechanically seamed panels, because the seam is folded closed along its full length and sits higher above the water. We measure the pitch of every roof plane and write the panel choice for each one into the spec, so you know exactly what goes where and why.
What a good standing seam job looks like up close
- One panel from eave to ridge. Each panel is formed on site to the length of its roof plane, with no mid-slope laps.
- Clips that let the panels move. Steel grows and shrinks with Texas heat; clips hold it down without pinning it, so it doesn't oil-can or pull fasteners.
- Bent flashings, not caulk, at walls, chimneys, valleys, skylights and pipes.
- High-temperature underlayment made for metal, over a deck we've checked and repaired.
- Clean tie-ins where an addition meets the original house, so water always sheds onto the metal.
City of Lake Dallas permits for a metal roof
Lake Dallas is plain about it. The city's Development Services FAQ says a permit is required to replace roof shingles, and a metal re-roof is the same kind of work. A few more rules from the city's permits page that matter on a roof job:
- Contractors register with the city before starting work. Registration is $100 (state-licensed trades are exempt from the fee). A homeowner doing their own non-trade work on a homesteaded house doesn't have to register.
- Start before the permit, pay double. The city doubles permit fees on any work that begins before the permit is issued.
- Inspections are done by a third party. Lake Dallas doesn't have its own inspector; it contracts with Bureau Veritas, which schedules and performs the inspections and reports back to the city.
- Patios and accessory buildings are planned separately. A patio needs a plot plan and building plan, and a repair needs a permit when it touches a structural part like a roof support. Accessory buildings over 120 square feet need plot, building and foundation plans, and the city says plan review on that kind of project can take up to 10 business days.
The city's adopted codes are the 2018 International Residential and Building Codes, effective May 23, 2019, with North Central Texas Council of Governments and Lake Cities Fire Department amendments. We register, file the application, call for the inspection and give you a copy of the permit before work starts.
Hail and standing seam in Lake Dallas
NOAA's Storm Events Database lists 59 reports of hail 1.75 inches (golf-ball size) or larger within about 10 miles of Lake Dallas from 2016 through the September 2026 update. The worst day close to home was March 26, 2017: NOAA lists 2.75-inch hail in Lake Dallas, less than a mile from the center of town, and 4.25-inch hail at Corinth about four and a half miles away. On March 14, 2024, 3.5-inch hail fell near Bartonville about six miles southwest and 2-inch hail about two miles west of town, and on June 11, 2023, 4.25-inch hail fell near Bartonville and 1.5-inch hail in Lake Dallas itself. The most recent golf-ball-size report nearby was 2-inch hail near Carney on June 2, 2026.
No roof is hail-proof, and very large hail can dent steel. Standing seam doesn't crack, curl or lose granules, so it usually keeps shedding water after storms that ruin shingles. See Class 4 metal roofs and insurance. Texas insurers must offer a premium credit for UL 2218 impact-rated roofs, but each company sets its own amount, and Class 4 earns the largest. We can't promise a discount; ask your insurer for their figure in writing. After a qualifying install we fill out TDI Form PC068 for you. If you file an insurance claim, we document the damage and meet your adjuster on the roof. Texas law requires you to pay your deductible, and a contractor may not waive, absorb or rebate it. We never will. In Texas you generally have 1 year from the date of loss to file; check your policy.
Roofs near the shoreline
Homes near the water in Lake Dallas get more wind across open water and more humid air than homes a few miles inland. On a metal roof, that shows up at the eaves and rakes, where wind gets under trim first; at the fasteners, which should be stainless or coated for the exposure; and in the attic, where humid air meets a cool deck. We set fastener and clip spacing at the edges for the exposure, use trim and closures made for the panel, and check ventilation before the new roof goes on.
Why it matters that we form our own panels
- One piece from eave to ridge. We cut standing seam and R-panel to the length of each roof plane, so long runs don't need mid-slope laps.
- 24 or 26 gauge on every standing seam and R-panel roof. See 26 vs. 29 gauge.
- No waiting in a panel shop's queue after a hailstorm, when everyone needs a roof at once. Metal lead time is typically 1 to 2 weeks.
- Flashings bent for the panel, not caulked: walls, chimneys, valleys, skylights and pipes.
- Every inspection comes with a free digital photo report, so you see what we see.
