Why more Houston homeowners are asking about metal
Metal roofing in Houston used to mean barns, sheds and rural shops. It now shows up on farmhouse-style homes in new subdivisions, on renovated bungalows and on houses rebuilt after storms. The appeal is easy to see: long panels with few laps, systems that carry published wind uplift ratings, and finishes that can reflect a lot of Gulf Coast sun.
It is still a big decision. The price, the way metal behaves in hail and the way some insurance policies treat it all differ from a shingle roof. This page sets out the choices, the questions to ask and the rules that apply, so you can talk to a roofer with your eyes open.
Houston Expert Roofers does no roofing work. The number is a no-cost referral line. Day or night, its automated assistant asks what you have in mind and transfers you to an independent, locally owned roofing company that installs and repairs metal roofs. That company quotes and does the work.
Metal roof examples: the main types you will be offered
Most quotes in greater Houston come down to two families of panel, plus a few specialty products. The difference that matters most is how the panel is fastened.
| Type | How it is fastened | Where you see it | Trade-offs |
|---|---|---|---|
| Standing seam | Concealed clips under raised seams; no screws through the face of the panel | Modern and farmhouse-style homes, higher-end re-roofs, low-slope sections | Fewer exposed holes to maintain; usually costs more and is harder to repair one panel at a time |
| Exposed fastener (ribbed or corrugated) | Screws with rubber washers driven through the panel face into the deck or purlins | Barns, shops, carports, patio covers, some homes | Lower cost; hundreds of washers that age in the sun and need checking |
| Metal shingles, shakes or tile profiles | Interlocking pieces shaped to look like other roofing | Homes where the neighborhood expects a shingle or tile look | May fit deed restrictions more easily; more pieces and laps than long panels |
Panel makers' own comparisons describe exposed-fastener panels as the lower-cost choice and note that their screws must be checked and sometimes tightened over the life of the roof, while standing seam clips stay hidden under the seams.
Gauge, metal and coating
Steel thickness is sold by gauge, and a lower number means thicker metal. Residential steel panels are commonly 22, 24, 26 or 29 gauge. Angi's guide to gauges suggests 24 gauge where hail is common, describes 26 gauge as the most common choice for homes because it balances durability and cost, and suggests 29 gauge for sheds and outbuildings where looks matter less. Steel panels also carry a metallic coating under the paint, most often galvanized (zinc) or Galvalume (an aluminum and zinc alloy), and the two hold up differently around salt. If you live near Galveston Bay or Clear Lake, ask the roofer what the panel maker's warranty says about distance from salt water before you choose a metal.
Heat, wind and noise in a Houston summer
Heat and cool finishes
Roof temperature depends mostly on reflectance and emittance. ENERGY STAR cites Lawrence Berkeley National Laboratory: a clean white roof reflecting 80 percent of sunlight stays about 50 degrees Fahrenheit cooler on a summer afternoon than a gray roof reflecting 20 percent. Berkeley Lab also tested cool pigments on metal panels: a cool brown reflected about 27 percent of sunlight, against about 8 percent for a conventional brown.
Wind uplift ratings
Metal panels are rated by uplift testing. For a TDI product evaluation, formed metal panels must be tested to UL 1897, UL 580, ASTM E1592 or FM 4474, and the published evaluations list how much uplift the panel resists at each clip or fastener spacing. Closer spacing usually means a higher rating, so the spacing on your roof should match the rating you are relying on.
Rain noise
The loud metal roof most people remember is on a barn with no deck and no insulation. Manufacturers note that panels over a solid deck, underlayment and an insulated attic sound much like a shingle roof inside the house. Ask what deck and underlayment the roofer plans to use.
Hail, cosmetic damage and your insurance
Hail can dent a metal roof without letting water in. That gap between how a roof looks and how it works is what insurance policies argue over. The Texas Department of Insurance lists four points for homeowners considering metal: a premium discount is not offered by every insurer and varies when it is; metal can still be dented by hail, debris and branches; a discount may come with conditions such as an exclusion for cosmetic damage; and coverage terms can change at renewal.
The idea goes back a long way. A 1998 TDI bulletin approved an optional homeowners endorsement that excludes cosmetic hail damage on impact-resistant roof coverings that earn a premium credit, defines cosmetic damage as a change in appearance that does not let water through or stop the roof from doing its job, and makes the endorsement void unless the policyholder signs it. The Texas Windstorm Insurance Association's manual also includes a cosmetic damage exclusion endorsement (TWIA 420) for residential policies, covering cosmetic hail damage to roof coverings.
None of this means metal is a poor choice. It means you should read the policy before you buy the roof:
- Does my insurer give a discount for this roof, and how much?
- Would a cosmetic damage exclusion be added, and how does the policy define it?
- Is the panel rated for impact resistance under UL 2218, and does that matter to you?
- What could change at renewal?
The deductible is yours to pay. The Texas Department of Insurance says it is illegal for a contractor to offer to waive, rebate or absorb your deductible, and a contract of $1,000 or more paid with insurance money must include a notice saying so. A roofer also may not act as your public adjuster on a property it works on. Treat any offer to "cover the deductible" as a reason to call someone else.
HOAs, deed restrictions and permits
Many subdivisions around Houston have deed restrictions and an architectural review committee that approves roof materials and colors. Texas Property Code section 202.011 limits what a property owners' association can do, but its wording is about shingles: an association may not bar an owner who is allowed to install shingles from choosing shingles designed to resist wind and hail, to improve heating and cooling efficiency or to generate solar power, as long as they resemble the shingles allowed in the subdivision, are at least as durable and match the look of the surrounding property. A switch to standing seam panels is not clearly covered by that protection, so read your restrictions and get the committee's approval in writing before you sign a contract. Metal shingle and tile profiles exist partly for this reason.
Inside the City of Houston, a re-roof needs a residential roofing permit from the Houston Permitting Center; roof covering work up to 100 square feet in total is exempt. Suburban cities and the coastal windstorm area have their own rules, covered on each town page.
Coastal windstorm rules. In the Texas Department of Insurance's designated catastrophe area (Brazoria, Chambers, Galveston and the other first-tier coastal counties, plus, in Harris County, Morgan's Point and the parts of La Porte, Pasadena, Seabrook and Shoreacres inside city limits and east of State Highway 146), most roof work must meet the windstorm building code and be inspected while it is under way (TDI exempts repairs to less than 100 square feet of roof covering that do not touch the decking). When it passes, TDI issues a certificate of compliance (form WPI-8), which the Texas Windstorm Insurance Association uses to decide whether it can insure the home. Ask the roofer, in writing, who schedules the inspection and when you will get the WPI-8.
Barns, shops and outbuildings on acreage
Out toward Magnolia, Tomball, Waller County and the rural edges of Fort Bend, plenty of properties have a shop, barn or carport under exposed-fastener panels. Those roofs need different care from a house: fasteners that have backed out or lost their washers, rust where panels overlap, trim lifted by wind and ridge caps that have worked loose. If a barn roof is leaking or rattling, mention it on the call and ask the roofing company you are connected with whether it works on outbuildings.
Tell the line whether it is a new metal roof, a repair or an outbuilding, and where you live. The local roofing company you are put through to sees the roof for itself and writes up its own price, which should name the panel, gauge and finish.

How a metal roofing call works
- Call the numberAn automated assistant answers (832) 662-4107 at any hour and asks which service you need, since the line also takes heating, cooling, pressure washing and water damage calls.
- Describe the roofA leak, missing shingles, hail, a limb on the roof or an old roof you want looked at, plus your part of greater Houston and how urgent it is.
- Get put throughYour call is transferred to an independent, locally owned roofing company, which hears a short summary before it picks up.
- Deal with the roofer directlyIt inspects, quotes and does the work, and you pay it (or your insurer does, as you arrange). If it misses the call, it gets your name, number, city and need to call you back.
Texas has no state roofing license. No state agency licenses roofing contractors in Texas, and a 2025 bill to create one (HB 3344) did not reach a vote of the full House before the session ended. So check what you can: a certificate of liability insurance sent to you, a written contract with the full scope, a permit where your city requires one, local addresses you can drive past, and the shingle maker's warranty registration. Some cities also ask roofers to register. The line does not check any of this for you. How to check a roofer before you hire.
