I-35, the toll roads and how the area is laid out
Interstate 35 splits Round Rock into an older, more established east side and a faster-growing west side, with SH-45 and the toll roads connecting the newer subdivisions. The east side sits closer to the blackland prairie, where expansive clay soil swells and shrinks with the weather. Homes there can shift slightly over the years, and movement can open gaps at flashing or around walls.
Along the I-35 corridor you also find strip centers, warehouses and offices with flat or low-slope roofs. Their needs are different from a pitched shingle roof on a family home, and the right crew depends on which one you own.
