On open Ellis County prairie, a solid patio cover is often the only real shade a back patio gets. Posts sit on footings planned for the clay under your Avalon yard.

An insulated roof keeps radiant heat off the patio through 96-degree July highs and quiets hail, which Ellis County saw in 106 reports from 2021 to 2025.

A louvered or fixed pergola gives an Avalon patio filtered shade where there are few trees to provide it, and the frame can carry a fan or lights.

Screens let an Avalon patio stay open to the breeze off the prairie while keeping out insects. A solid roof overhead makes it usable in rain too.

A sunroom on a slab we have checked for clay movement gives an Avalon home a bright room for spring and fall, when Ellis County weather is mild.

An all-season room adds insulated walls, roof and glass and can share your heating and cooling, comfortable on a 35-degree January morning in Avalon.
A well-built solid cover in Avalon handles Ellis County hail better than an open frame, though no cover is hail-proof. The NOAA Storm Events Database lists 106 hail reports in the county from 2021 through 2025, 90 of them one inch or larger, with a largest stone of 3.75 inches. May, June and April had the most. The county also logged 20 thunderstorm wind reports and 6 tornado reports. An insulated aluminum cover adds a thick foam core and cuts storm noise, and the posts are anchored for wind.
For Avalon sun, an insulated cover gives more relief than a pergola, because it blocks the sky and keeps heat from radiating down. Ellis County’s average July high is 96 degrees, and on open prairie there is little tree cover to help. A shade pergola still makes sense if you want light and air, especially with adjustable louvers you can close at midday. The estimator can show where the shadow of each option falls on your patio during the afternoon, which makes the choice easier.
An all-season room suits an Avalon home if you want year-round use, and a sunroom suits it if spring and fall are the goal. Ellis County runs from a 35-degree average January low to a 96-degree July high. A glass-walled sunroom gives light but is not built to hold heating or cooling. An all-season room addition has insulated walls, roof and glass and can connect to your system. On Blackland clay, both need a slab that is checked before walls go up.
An Avalon property should plan for full sun, open wind and clay soil before adding a patio cover. Avalon has no census profile of its own, so our estimator sees the house first instead of guessing at its age. Ellis County is almost treeless away from the streams, which means a cover may be the main shade on the lot and will catch wind from every side. Anchoring, roof pitch and where water runs off all matter. Look through the patio project photos to compare attached and freestanding designs.
Blackland clay affects footings in Avalon because clay swells when wet and shrinks when dry, and a cover tied to the house has to live with that movement. Ellis County soils are mostly calcareous, marly and variegated clays and clay loams, and the alluvial soils near creeks are mainly clay. With slightly less than 36 inches of rain a year, the ground can swing between soaked and dry. We size and set footings for that, and plan gutters so roof water lands away from the slab and posts.
Census figures for Avalon are not published, so we do not assume the age or style of your home. The estimator checks the roofline, slab, windows, siding and doors in person and plans from what is there.
Avalon is in Ellis County, 939 square miles of Blackland Prairie with level to rolling terrain between 300 and 700 feet. Away from the streams the land is almost treeless, and the soils are mostly calcareous, marly and variegated clays and clay loams. Rainfall averages slightly less than 36 inches a year.

If your Avalon address is outside any city limits, Ellis County reviews the permit; if it is inside, the city does. American Eagle Builders confirms which at the estimate and files the paperwork.
Which office reviews the job depends on whether your address is inside the City of Avalon or in unincorporated Ellis County. We confirm that at the estimate and file the paperwork ourselves.
Our DFW permit guide covers the rest, including how an HOA submittal fits in.
A crew based near Red Oak serves Avalon, about 22 miles away, and our office in Arlington schedules the work. We book a free estimate first, then set the build once the design and permit are ready.
Yes. Ellis County soils are mostly calcareous clays and clay loams that swell when wet and shrink when dry. Footings and the connection to the house have to allow for that, and roof water should drain away from the slab. We plan for it at the first visit.
Photograph the damage and report it to your insurance company. Avoid paying a large deposit to anyone who shows up at the door after a storm. We can inspect the cover and give you a free written estimate. Coverage depends on your policy.
Size, glass type, insulated or uninsulated walls and roof, slab condition on clay soil and any heating, cooling or electrical tie-ins drive the cost. We measure at your home and give a firm written estimate at no charge. Financing programs are available.

“I had a patio cover installed. They first said the work would begin about six weeks out but to my surprise it began three weeks out. Jim was my installer and he went above and beyond to ensure I had a strong and properly supported patio cover built. Very pleased with the result and received a very favorable and fair price.”
