Gutter Installation in Round Rock, TX

Local know-how

Round Rock pays part of rainwater gutters

Round Rock’s Water Conservation Program offers a rainwater harvesting rebate to direct city water customers. The October 2025 rebate sheet lists $0.50 per gallon of storage, 50 percent back on pad material, pumps and overflow or first-flush parts, and 25 percent back on gutters specific to water collection, with a $50 minimum and an $800 maximum per water account; the gutter portion is capped at a few hundred dollars and excludes labor.

Only direct City of Round Rock water customers qualify, not MUD customers, and barrels must be new. Apply before you buy, and check the current sheet, because the city announced no rain barrel sales in 2026 while its office is under construction.

Flash floods and the stormwater charge

Central Texas is flash flood country: Austin averages about 36.25 inches of rain a year at Camp Mabry, much of it in a few intense events. Round Rock charges a residential stormwater drainage fee of $6.75 a month (effective November 2026), based on impervious area. Gutters and downspouts do not change the fee, but they decide whether roof water soaks into your yard, fills a cistern or runs across the driveway into the street. See rainwater harvesting from gutters.

Limestone, caliche and slabs

Round Rock homes sit on slabs over shallow limestone and caliche with pockets of expansive clay. Water dumped at a slab corner wets the soil unevenly and can lead to cracked tile and sticking doors. Carry water several feet away onto ground that slopes off, or into a cistern. See downspouts and your foundation.

Metal roofs and 6-inch gutters

Metal roofs are common on newer Round Rock homes and shed water fast. 6-inch gutters with 3x4-inch downspouts, mounted so water does not overshoot, suit them. Hail also reaches Williamson County; heavier gauge dents less. See gutters for metal roofs and 5-inch vs. 6-inch gutters.

Costs and contractors

Angi puts the average gutter installation project in Austin at about $1,171, with most projects between about $689 and $1,664; there is no separate Round Rock figure. Texas does not license roofing or gutter contractors at the state level, so check insurance, local references and the written contract yourself. See our cost guide and how to choose a gutter contractor.
