Dallas asks more of a roof than most markets. Summer temperatures sit above 95F for long stretches, the sun is relentless, and hail arrives most years. Roughly three in five roof claims in this region are hail-related. Any material choice that ignores that is a choice made on the wrong criteria.
What Each Material Actually Does Here
- Asphalt shingle, 15 to 30 years. The default, best cost-to-protection ratio, easy to match slope by slope after a storm.
- Metal, 40 to 70 years. Reflects heat, sheds hail, outlasts everything else we fit. Higher up front.
- Tile, 50 years and up. Handsome and long-lived, but the structure has to carry the weight and the underlayment beneath it ages far faster than the tile.
- Slate, a century or more. The premium option, and a specialist job to repair.
- TPO and single-ply, 20 to 30 years. Low-slope and commercial, fails at the details rather than the field.
- Synthetic and composite, 30 to 50 years. Slate or shake appearance without the weight, and impact-rated.
Rough Cost Per Square Foot, Installed
- Asphalt shingle: $5.50 to $7.50
- Metal: $8 to $14
- Clay tile: $15 to $25
- Slate: $20 to $40
- TPO: $4 to $7
Permit fees in most Dallas municipalities run $200 to $500 on top. Those ranges move with material prices and with how complicated your roof is, which is why an estimate is written against your actual house rather than quoted off a table.
The Heat Argument
The EPA's work on cool roofs is clear: a reflective surface sends solar gain back rather than loading it into the building. In practice a lighter shingle runs meaningfully cooler than a dark one, and metal with a reflective finish runs cooler still. On a Dallas summer bill that is not a rounding error.
The other half of the same problem is ventilation. A reflective roof over a badly ventilated attic still cooks. We size intake and exhaust to the attic rather than replacing what was there.
The Hail Argument
Impact rating is measured under UL 2218, and Class 4 is the top of that scale. The Texas Department of Insurance publishes which carriers offer premium discounts for impact-resistant roofing, and those discounts shorten the payback on the upgrade considerably.
If you have claimed for hail more than once, that is the conversation to have before you replace like for like.
Choosing, Practically
Three questions settle most of it:
- How long will you own it? Under ten years, asphalt is hard to argue with. Longer, and metal or composite starts to win on total cost.
- What does the structure allow? Tile and slate need framing rated for the load. That gets checked before anyone quotes.
- What is the neighbourhood? HOA rules and the surrounding architecture narrow the field, sometimes to one answer.
What We Would Say
For most Dallas homes, architectural asphalt with a Class 4 rating and correctly sized ventilation is the sensible specification. For a house you intend to keep, metal changes the replacement cycle entirely. For tile and slate, the deciding factor is the structure, not the budget.
