As of this week, fire danger is rated extreme across much of our service area — Waco, Hillsboro, Gatesville, and Meridian among them — and burn bans are in effect throughout Central Texas. Bosque County commissioners issued a 90-day ban on August 17. Statewide, more than 165 counties are on the Texas A&M Forest Service burn ban map. Fire resistant roofing in Central Texas is ore important now than ever.
Here’s the part most homeowners don’t know: in wildfires, homes are usually not lost to the wall of flame. They’re lost to embers — and the roof is where embers land.
This isn’t a sales pitch. Most of what follows costs nothing and takes an afternoon.
Embers, not flames
Research from the Insurance Institute for Business & Home Safety and post-fire investigations consistently find that the large majority of homes destroyed in wildfires are ignited by wind-blown embers, not by direct flame contact. Some estimates put that figure as high as 90%.
Embers travel. They ride the wind a mile or more ahead of the fire front, and they arrive in volume — thousands per square foot, over a period that can last from twenty minutes to several hours.
Then they look for fuel. Your roof is the largest, most exposed surface on your house, and it has all the places embers like: valleys where debris collects, gutters packed with dry leaves, and vents that lead straight into your attic.
The pattern that shows up repeatedly in post-fire surveys is a home that ignited from the inside or the edge, not the front.
The three weak points, in order
1. Vents and attic openings. This is the most common entry route. Standard attic, soffit, and gable vents are designed to move air — and they move embers just as efficiently. Embers that get through can ignite attic insulation, rafters, or stored boxes. A quarter-inch mesh screen passes embers readily. One-eighth-inch metal mesh is the standard recommendation, and it’s a cheap fix.
2. Debris on the roof and in gutters. IBHS documented a home in California’s 2018 Camp Fire where embers ignited debris in the gutter, which then burned the roof edge and deck. The roof covering itself wasn’t the problem — the leaves sitting on it were. Their lab testing also shows vinyl gutters melting and falling away, sometimes more slowly than it takes the roof deck to ignite.
Leaves in your gutter are, functionally, kindling attached to your roofline.
3. The first five feet around the house. IBHS research found that creating a noncombustible buffer in the five feet closest to a home cuts its risk of igniting in half. That means no mulch, no firewood stacks, no combustible groundcover, no wicker furniture against the wall. River rock, gravel, and hardscape instead.
What Class A actually means
Roof coverings are fire-rated Class A, B, or C under ASTM E108 / UL 790 — testing that measures flame spread and resistance to burning brands. Class A is the highest fire resistant roofing in Central Texas.
The good news for most Central Texas homes: modern fiberglass-mat asphalt shingles typically carry a Class A rating as installed. If your roof is less than 20 years old and shingled, you’re probably already there.
Metal goes a step further — it earns Class A ratings and the material itself is non-combustible, so it can’t ignite from an ember landing directly on it. That’s a genuine advantage on rural properties with grass-fire exposure, and it’s one of the reasons we recommend it in that situation in our metal versus shingles comparison.
But note what the Camp Fire example shows: a Class A roof with debris on it is not a Class A roof. The rating describes the covering, not the pine needles sitting in the valley. Material choice matters less than maintenance here.
An honest word about your actual risk
Roofing companies have an obvious incentive to make this sound scarier than it is, so let’s be straight.
If you’re in a subdivision in central Waco, Hewitt, or Temple, your wildfire risk is low. Mowed lawns, paved streets, and neighbors on all sides make an ember storm unlikely to find fuel. Clean your gutters because it’s good practice, not because your house is in danger.
If you’re on acreage in Bosque, Coryell, Hill, Falls, or Limestone County — pasture, brush, cedar, a treeline near the house — this is a different conversation. Texas grass fires move fast in these conditions, and rural response times are longer. The five-foot buffer and the vent screens are worth doing this week.
Texas has real history here: the 2011 Bastrop fires, the 2022 Eastland Complex, and the 2024 Smokehouse Creek fire in the Panhandle, the largest in state history. Central Texas is not California, but the physics of embers are the same everywhere.
What to do this week (free, no contractor needed)
Under a burn ban there’s not much yard work you can do. These are all allowed, and all worth doing:
- Clear your gutters. Dry leaves at the roof edge are the single most fixable ignition risk on the house.
- Clear valleys and roof debris. Especially where a roof plane meets a wall, and anywhere leaves pile up. Under solar panels too.
- Check your vent screens. If you can see quarter-inch mesh or open vents, upgrade to one-eighth-inch metal mesh. It’s an afternoon and under $50 in materials.
- Clear the first five feet. Move firewood, mulch, and patio furniture away from the walls.
- Look under the deck. Accumulated leaves under a deck are a classic ignition point.
- Don’t get on the roof in 100-degree heat. Seriously. If it’s not safe to walk it, call someone or wait for a cooler morning.

Frequently Asked Questions
Are metal roofs more fire resistant than shingles? Both can carry a Class A fire rating, which is the highest under ASTM E108 and UL 790. The difference is that metal is non-combustible as a material, so it cannot ignite from an ember landing on it, while asphalt shingles achieve their rating as a tested assembly. For rural properties with grass or brush exposure, that distinction is meaningful.
Do asphalt shingles have a fire rating? Yes. Modern fiberglass-mat asphalt shingles typically carry a Class A fire rating as installed, the highest classification available. Older organic-mat shingles and untreated wood shakes do not perform as well.
What actually causes homes to burn in a wildfire? Wind-blown embers, in the large majority of cases — not direct contact with the flame front. Embers can travel more than a mile ahead of a fire and land by the thousands per square foot. They ignite debris in gutters and roof valleys, or enter attics through vents.
How do I protect my roof from wildfire embers? Keep gutters and roof valleys clear of leaves and debris, screen attic and soffit vents with one-eighth-inch metal mesh, and maintain a noncombustible buffer in the first five feet around the house. IBHS research found that buffer alone cuts a home’s ignition risk roughly in half.
Does a fire-resistant roof lower my insurance? Sometimes, though it varies by carrier and is far less standardized in Texas than the impact-resistant hail credits. Texas has a defined credit structure for Class 4 impact-rated roofing, explained in our guide to the Class 4 discount. Ask your agent specifically about fire-rating credits.
Can I burn brush during a burn ban? No. Burn bans prohibit outdoor burning, and violations carry fines. Negligently starting a wildfire that causes injury or property damage can bring criminal charges. Check the Texas A&M Forest Service burn ban map for your county’s current status.
