  • Drip edge must be installed per the locally adopted residential code.
  • Ice and water shield may be required based on specific roof slopes.

Do You Need a Permit to Replace a Roof in San Antonio

In almost every case, yes — a full roof replacement (a tear-off and re-cover, or a complete reroof) requires a building permit in San Antonio, issued by the City of San Antonio Development Services Department. Replacing the roof covering is regulated work because it affects the structure’s weather envelope and, on a tear-off, exposes the sheathing for inspection. A licensed roofing contractor usually pulls the permit, and an inspection may be required after the old material is removed and again at completion. Permit-free roofing is generally limited to minor repairs — not a whole-roof replacement.

Roof Repair vs. Replacement: When You Need a Permit in San Antonio

The dividing line in San Antonio is usually the scope of work. Small repairs — patching a leak, swapping a few damaged shingles, or fixing flashing — often don’t require a permit. A full replacement, a tear-off down to the deck, adding a second layer over the old shingles, or any change to the roof structure (rafters, trusses, sheathing) generally does. Some cities also cap how much roof area you can repair before it counts as a replacement. Because that threshold and any wind- or fire-zone rules vary, confirm the cutoff with the City of San Antonio Development Services Department — the requirements above list what San Antonio expects.
