Allison Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs out here for over fifteen years, and if there’s one thing I tell every homeowner in Allison, it’s that your roof is living on borrowed time. We sit right in that nasty little corridor where the dry, hot air off the western plains slams into the humid Gulf moisture that pushes up from the coast. That collision doesn’t just give us pretty sunsets—it stacks the atmosphere like a loaded spring, and when those late-April and May storms roll through, they don’t mess around. The hail we get isn’t that polite pea-sized stuff you see in other parts of the state; it’s often golf-ball or even baseball-sized, and because the wind shear up high is so strong, those stones get thrown sideways at your shingles like a million little hammers. I’ve pulled off roofs where the hail actually bruised the plywood underneath, not just knocked the granules off.

And it’s not just the springtime supercells, either. Our geography plays a dirty trick on us in the fall, too. Allison sits on that gentle rise of land just east of the Brazos River bottoms, and that subtle elevation change acts like a ramp for straight-line winds. When a squall line comes barreling through in October, those downdrafts hit the ground and accelerate, easily hitting 70 or 80 miles an hour. That’s the kind of wind that doesn’t just lift a few tabs—it peels entire sections of shingles right off the deck, especially if the roof is over ten years old and the sealant has gotten brittle from our brutal summer heat. So between the sideways hail in the spring and the hurricane-force gusts in the fall, your roof here takes a beating that most other towns never see. It’s not a matter of *if* you’ll need a repair, it’s a matter of how many times you’ll be calling me before you finally give in and let me do a full replacement.
