A soil map with a frontage road
In Travis County the highway is also a soil map. Texas A&M AgriLife Extension describes I-35 as the line that physically separates the Edwards Plateau, with thin soils over exposed limestone, from the Blackland Prairie to the east. A roofing contractor working Travis County has to think about both halves, because the trouble that shows up on a house changes at the frontage road.
East of the interstate, the black and reddish clays are deep and dense. They shrink and swell with moisture, opening cracks wide enough to heave fence posts and patios. When a porch drops or a ceiling crack keeps coming back on that side of the county, we check the ground before we blame the shingles. If the cause is in the soil, we tell you so and point you to a foundation specialist before anyone sells you a roof. West of I-35, the problem is different. Houses sit on rock under big trees, and the threat comes from fire and falling limbs.
