Moore has been hit harder than almost any town in America by tornadoes, and that history shapes how people here think about every structure on their property. Barn Brothers takes that seriously. The metal carports Moore OK homeowners ask for tend to come with real questions about anchoring, gauge, and what survives versus what doesn't. We don't oversell. A carport is a carport, not a storm shelter, and we'll be straight with you about what proper engineering does and doesn't do. We've installed all over Moore, from the rebuilt neighborhoods along SW 4th Street where the 2013 storm tracked through, out to newer additions near 19th Street and the I-35 corridor. Moore's lots are a mix, some older smaller post-war parcels in the historic core, and bigger newer builds south and west. We anchor properly, we use heavier framing where wind exposure justifies it, and we don't cut corners on the parts you can't see once it's standing.

Permits
Most: none
Moore runs permits through its Community Development department, and accessory structures over 120 square feet typically require a building permit. After the 2013 storm Moore strengthened its building code requirements, including for residential additions and accessory structures, and inspectors here pay close attention to anchoring and structural details. Standard R-1 setbacks require 5 feet from side property lines and 25 feet from the front, with rear setbacks varying. Lots inside the city's overlay districts along major corridors carry additional design review. HOA presence varies, older Moore neighborhoods rarely have active HOAs while newer additions south of 19th Street and west toward I-44 commonly do. Floodplain overlays affect properties along Moore Creek and smaller drainage paths. We provide engineering details and anchoring specs to support your permit application.
Moore sits in Cleveland County, near Veterans Memorial Park, with road access via I-35 / SW 4th Street. The 2018 IBC wind speed map puts most of this region in the 115 MPH ultimate design wind zone (Risk Category II, Exposure C), which converts to roughly a 90 MPH nominal basic wind speed on engineered drawings.
Standard 14-gauge framing with mobile-home anchors and 29-gauge roofing rates to about 90 MPH — exactly the minimum, with zero margin. Our certified units are engineered up to 140 MPH wind and 35 PSF snow load depending on bracing, anchor pattern, and roof style. Out on open ridges and exposed pasture, we strongly recommend going certified at minimum 105 MPH.
Anchoring matters more than gauge. Most of Cleveland County sits on the kind of clay-loam soils that give standard 30-inch mobile-home rebar anchors trouble — they lose 30–50% of their pull-out strength in dry months. We use 48-inch helical/auger anchors for any carport over 18 feet wide on dirt, concrete wedge anchors on slabs, and asphalt anchors with epoxy bonding on blacktop. Expect $80–$150 in anchor upgrades over the base “mobile home anchor” pricing other companies advertise. Worth every penny.
Snow load is low, ice is real. Design ground snow load for this part of Oklahoma is roughly 8 PSF under ASCE 7-16. But the 2021 ice storm dropped 1–2 inches of solid ice across much of the state. A quarter-inch of ice on a 20×26 vertical-roof carport adds roughly 400–500 pounds of point load. Vertical roof sheds it; horizontal-panel regular roofs trap it. That’s why we push vertical hard for any building over 24 feet wide.
We deliver and install across Cleveland County and surrounding counties. Lot pickup at 227 1/2 N Main St., Waurika, OK 73573.

Apply with my quoteA bare-bones 20×21 carport runs in the low four figures; a fully enclosed 30×41 shop can push past $20,000. Here are the four legitimate ways to pay for one — we’ll quote all of them on the same email and let you decide.
Pay cash and we discount 3–5% off the financed price. On a $6,800 carport that’s $200–$340 back in your pocket. Card payments accepted up to $10,000 (2.9% processor fee passed through).

Every Moore build carries frame, panel, and workmanship warranties, with optional engineer certification for permits or insurance.
Frame warranty
20 years
Every leg, rafter, brace, and purlin warranted against rust-through and structural failure for 20 years from install. Hot-dipped galvanized 14-ga steel standard, 12-ga upgrade available. G90 zinc spec (0.90 oz/sq ft both sides) — the agricultural building workhorse standard.
Panel warranty
10 years
29-ga sheet panels carry a 10-year manufacturer warranty against fade, chalk, and chip-through. Silicone-modified polyester paint over galvalume substrate — the same material on most commercial pole barns across Oklahoma. 26-ga upgrade extends panel warranty to 20 years (+8–12% panel-line cost).
Workmanship
1 year
Anything our crew installs is warranted for 12 months from completion. Loose bolts, misaligned panels, leaks at penetrations, anchor failure on level ground — we come back and fix it on our dime. Most claims hit in the first 90 days, almost always after the first big windstorm.
For buyers who need stamped drawings — typically those building inside Moore city limits, financing through a bank that requires it, or installing in flood-prone zones — we offer engineer-certified plans for an additional $375–$650 depending on building size. Certified buildings are engineered to specific wind and snow loads (standard for this part of Oklahoma is 90 MPH wind, 8 PSF snow; we can spec up to 140 MPH wind / 35 PSF snow). Stamp issued by a licensed Oklahoma PE and accepted by every Cleveland County permit office we’ve worked with.
What is not covered: acts of God (tornadoes, hail over 1.5″, named storms), modifications by third parties, damage from impacts (tractors, livestock, vehicles), and rust from coastal salt exposure. Trim accessories (gable ends, ridge caps) are covered for 5 years rather than 10 because of the way the bend stresses the paint.
After 20+ years of building across Oklahoma, here’s the straight talk on three options Moore buyers actually consider.

“I called three companies about a metal garage for my tractor. Two of them quoted me higher and wanted six weeks just to get a stamped plan. Marcy had me a written quote the same afternoon and the crew was here 18 days later. Whole thing went up in a day and a half. The roll-up door tracks were a hair off when they finished — they came back the next Friday on their own and adjusted them, no charge, no argument.”
★★★★★
“Bought a small travel trailer last spring and needed something to keep the sun off it. I am on a fixed income, so the rent-to-own option was the only way I could swing it. The lady on the phone walked me through the whole thing twice without making me feel dumb for asking. The crew showed up at 7:45 a.m. like they said they would, and the foreman shook my hand before he left. Little things matter.”
★★★★★
“Needed cover for round bales before fall cutting. Called several others — all of them wanted 8 to 10 weeks. Barn Brothers had it standing in 23 days flat. The crew showed up at 7 a.m., were eating lunch in the truck by noon, and packed up at 4. I have had it through one round of those April storms now and it has not creaked. Worth every dollar.”
