Patio Covers in Dumas, TX
The highest verified shrink and swell figures anywhere in this service area sit directly under Dumas, and the survey says so numerically.
No obligation. Every estimate starts at the house, looking at the slab, the wall you would attach to and where the afternoon sun actually lands.

Dumas at a glance
Every figure below comes from a named public source. Where we could not verify something, this page says so instead of filling the gap.
Population from ACS 2024 five-year estimate. Design wind and snow from ASCE 7-16 wind and snow hazard data; permit and code details from each jurisdiction's own published material.
Permits
A real permit programme running an older code
We confirm the current position for your specific address before quoting. Fee schedules and code adoptions change, and a page that was right last year is not a substitute for asking.
Dumas has adopted the 2012 International Building Code, including appendix chapters B and C, by Ordinance 1122 section 1, adopted 20 October 2014, with a related Ordinance 1212 from June 2022. Local amendments to the 2012 IBC are attached to Chapter 3 of the city code.
We could not read the amendment attachment itself, so any local amendments to wind speed or foundation requirements remain unverified. The city code also carries dedicated contractor registration and permits and inspections articles, which suggests contractor registration is required. We confirm both before quoting rather than assuming.
The department is Building Permits and Inspections at City Hall on West 6th Street, open Monday to Thursday and Friday mornings.
The ground
Sherm clay, and the cleanest soil fact in the region
Most towns' soil surveys leave you inferring which unit sits under the town. Moore County does not. The survey maps seven associations and states that the Sherm association covers about 50 percent of the county, and Sherm soils make up about 90 percent of that association. Dumas sits in it.
Sherm is classified fine, mixed, superactive, mesic Torrertic Paleustolls. It runs 38 to 48 percent silicate clay, its linear extensibility is 7 to 9 cm to a depth of 100 cm, permeability is slow, and surface cracks exceed 50 cm deep when the soil dries. That last figure is the highest verified shrink and swell number anywhere in this service area.
What that means for a patio cover: the footings are not negotiable, the depth matters, and a post anchored to a four inch slab sitting on ground that opens half-metre cracks is not anchored to anything. It also means drainage away from the structure is a structural consideration rather than a landscaping one.
One naming coincidence worth clearing up. There is a USDA soil series called Dumas, fine-loamy Aridic Paleustolls with its type location in Sherman County, but the Dumas-Dalhart association is a minor Moore County unit and it is not the one under the town.
On the record
The 1 May 2022 hail event
On 1 May 2022 the National Weather Service logged 1.75 inch hail at Dumas at 7:00 pm, with further reports around midnight into 2 May, alongside measured wind gusts of 58 mph at 6:35 pm and 72 mph at 6:40 pm.
A 72 mph gust with inch and three quarter hail in the same five minutes is the combination that matters for an outdoor structure. Hail dents panels. Wind at that speed drives the hail sideways and loads the structure in uplift at the same time. Neither problem is solved by the roof material alone.
The market
A young working town shaped by one employer
Dumas has a median age of 30.6, and 25.1 percent of residents are foreign born, which is by a wide margin the highest share in this service area. Median household income is $63,788 and median home value is $156,300, with 4,827 households in 5,612 housing units.
The reason the demographics differ so sharply from every other town here is the JBS USA beef plant at Cactus just to the north, which processes up to 5,000 head a day with a predominantly immigrant workforce.
Practically, this is a mid-range market with young working households and real budgets. The shade argument lands well here: Amarillo's cooling degree days run 1,399 and Dumas sits at similar latitude with the same afternoon sun.

About building in Dumas
How bad is the soil movement in Dumas?
It is the highest verified in this service area. The Moore County soil survey states that the Sherm association covers about 50 percent of the county with Sherm soils making up about 90 percent of that association, and Dumas sits in it.
Sherm runs 38 to 48 percent clay with a linear extensibility of 7 to 9 cm to 100 cm depth, and surface cracks exceeding 50 cm deep when dry. Footing depth and drainage are the design response, and neither is optional here.
What code does Dumas build to?
The 2012 International Building Code including appendix chapters B and C, adopted by Ordinance 1122 on 20 October 2014, with local amendments attached to Chapter 3 of the city code.
We could not read the amendment attachment, so any local wind speed or foundation amendments are unverified. Dumas also has contractor registration and permits and inspections articles in its code, which we check before quoting.
Will hail wreck an aluminium cover in Dumas?
It will dent one. On 1 May 2022 Dumas recorded 1.75 inch hail at 7:00 pm along with measured gusts of 58 and 72 mph within five minutes of each other.
A thin aluminium skin over foam dents cosmetically in hail of that size without necessarily failing structurally. If dents would bother you, that is a real argument for a framed roof with a shingled or metal surface, and we would rather you decide that in advance.
