Should I put a metal roof or shingles on a Texas house?
Shingle is cheaper up front and is what most North Texas houses wear. Metal costs meaningfully more and lasts thirty to fifty years or more against the fifteen to twenty-five an asphalt roof gives in this climate, reflects heat out of the attic, and shrugs off weather that fractures a shingle. If you plan to be in the house a long time, metal usually wins on arithmetic; if you do not, shingle usually does.
Service life is the whole argument
A metal roof can last thirty to fifty years or more with little maintenance, and can often be repainted rather than replaced when the finish tires. An asphalt roof in North Texas heat and hail does well to see twenty.
Run that over forty years and the comparison is one metal roof against two shingle roofs plus the disruption of a second replacement. That is the case, and it only holds if you are the one still living there.
What hail does to each
Hail fractures the mat of an asphalt shingle, which is invisible damage that turns into a leak years later. Hail dents metal, which is visible damage that stays cosmetic. Neither is desirable and they fail differently, and a dent that never leaks is a better outcome than a bruise that eventually does.
Gauge matters. A heavier standing seam panel resists denting better than a thin exposed-fastener panel, and it is worth asking what gauge is being quoted.
Heat, and the Texas summer
Cool metal roofing uses a reflective solar coating designed to minimize heat buildup and reduce air conditioning cost, with savings of up to forty percent on annual energy costs claimed for the system. In a climate where the attic runs over a hundred and thirty degrees in August, that is the benefit homeowners notice within one summer.
The recycled content argument is real too: most metal roofing contains thirty to sixty percent recycled material and is one hundred percent recyclable.
The objections, answered honestly
Noise is the first one and it is mostly a myth on a residential roof. A metal roof over solid decking and underlayment sounds much like any other roof from inside. The loud one people remember is a panel roof on open purlins over a barn.
Lightning is the second, and metal does not attract it. Insurance is the third, and some carriers offer a discount for an impact-resistant roof covering. Ask yours before you choose, because the answer varies by carrier.
Related questions
Can metal go over existing shingles?
Sometimes, and it is not always the right call. It saves the tear-off and it hides the decking, which is the thing worth inspecting on a roof old enough to replace.
Does a metal roof make the house hotter?
The opposite. A reflective coating sends solar heat back out rather than into the attic.
Will insurance pay to upgrade me to metal?
A policy pays to put back what was there. Where you upgrade, the claim covers the shingle roof and the upgrade is the difference.
How long does a metal roof take to install?
Longer than shingle. Panels are cut and fitted to the roof rather than laid in courses, and the trim and flashing detail takes time.
