For most Dallas homeowners the honest answer is: Class 4 impact-resistant composition shingles if you'll be in the house under 15 years, standing-seam metal if you'll be there longer and can absorb two to three times the upfront cost. Composition commonly runs $9,000 to $18,000 installed; standing-seam metal $25,000 to $45,000 or more. Metal lasts 40-plus years and reflects summer heat, but it dents in large hail and many Texas insurers exclude cosmetic damage on it. Composition is cheaper, familiar, and easy to insure, but in the DFW hail belt you may replace it two or three times over the life of one metal roof.
Cost and lifespan
Composition (architectural or Class 4): $9,000 to $18,000 commonly for a typical home. Rated 25 to 30 years, but in DFW heat and hail most are replaced at 12 to 20. Class 4 adds roughly 10 to 25 percent and often earns an insurance discount.
Standing-seam metal: $25,000 to $45,000 or more. Commonly lasts 40 to 60 years with a Kynar finish. Over that span it can cost less than repeated composition replacements, but only if you own the house long enough to benefit.
Exposed-fastener metal: cheaper than standing seam, but screws and washers loosen with Texas thermal cycling and need maintenance every 10 to 15 years. Generally a better fit for barns and shops than for a primary residence.
Hail, insurance, and heat
Hail. Class 4 shingles resist bruising well and still get replaced when hail is large enough. Metal rarely leaks from hail but dents, and many Texas policies exclude cosmetic damage on metal, so a dented roof may be yours to live with. Ask your agent specifically before choosing metal.
Insurance premiums. Class 4 shingles commonly earn a discount from Texas insurers. Metal roofs sometimes do, sometimes don't, and the cosmetic exclusion can be added at renewal.
Heat. Light-colored metal with a reflective finish lowers attic temperatures noticeably in July and August and can trim cooling bills. Composition shingles absorb heat; ventilation and a radiant barrier help either way.
HOA, resale, and installer quality
HOA. Many Plano, Frisco, McKinney, and Irving HOAs restrict metal roofs or specify profile and color. Get written approval before signing. Composition in an approved color is rarely an issue.
Resale. Metal is a selling point in many DFW neighborhoods now, but buyers in tract-home subdivisions expect composition and may not pay extra for metal. A new Class 4 roof is a strong, simple resale signal.
Installer. Metal is unforgiving of bad flashing and fastening. Choose an installer who does standing seam every week, not a shingle crew taking a metal job.
