Permit process note
"A permit is required for any roof replacement/recovering or repair which exceeds 25% of the total roof area. The purpose of the permit is to ensure that the proper codes are being followed." The building permit must be approved and posted at the property prior to any work commencing, and all contractors must be registered to perform work in the City of Richardson.
Inspection requirements
"An inspection is required upon installation of the roof deck, (if applicable) and a final inspection is required upon completion."
Adopted code
"On April 24, 2023, the City of Richardson City Council approved the adoption of the 2021 International Codes and the 2020 edition of the National Electric Code, including regional and local amendments," including the 2021 International Building Code, 2021 International Existing Building Code, 2021 International Residential Code, 2021 International Mechanical Code, 2021 International Plumbing Code, 2021 International Fuel Gas Code, 2021 International Energy Conservation Code, 2021 International Fire Code, and 2021 International Swimming Pool and Spa Code, each with local amendments.
Drip edge
Required — Drip edge is required at eaves and rake edges of shingle roofs (IRC R905.2.8.5). The jurisdiction adopted the 2021 International Residential Code via the city's adopted 2021 IRC Amendments (single-page amendment table: R302 fire separation, R327 pools, fuel-gas sections only); that instrument, read in full, does not amend R905.2.8.5, so the code's drip-edge requirement stands as enacted local law. About drip edge
Mid-roof inspection
Required — "An inspection is required upon installation of the roof deck, (if applicable) and a final inspection is required upon completion." (City of Richardson Building Inspection, Roof Repair / Replacement page).
Impact-resistant roofing
Not required — City of Richardson Code of Ordinances Chapter 6, Article II, Sections 6-29 through 6-31 -- the "Richardson One- and Two-Family Dwelling Building Code," which adopts the 2021 International Residential Code and carries the city's local amendments to it, last amended by Ordinance No. 4464 adopted April 24, 2023 -- was read in full. The city amends the roofing chapter in two places, both concerned with fire: Section R902.1 as amended requires Class A, B or C roofing tested in accordance with UL 790 or ASTM E 108, and an added Section R904.5, titled "Fire classification," sets a Class C minimum and permits unclassified wood shingles or shakes on repairs replacing not more than 25 percent of an existing unclassified wood roof covering in any 12-month period. A fire rating is a different test from impact resistance. The regional amendment table the city publishes alongside its adopted codes carries five North Central Texas Council of Governments amendments, none of them to the roofing chapter. No UL 2218 or Class 4 impact requirement appears in the city's adopted code or its amendments.
Repair permit threshold
"A permit is required for any roof replacement/recovering or repair which exceeds 25% of the total roof area." (City of Richardson Building Inspection, Roof Repair / Replacement page).
Sales & use tax
8.25% combined (6.25% state + 1.00% City of Richardson + 1.00% Dallas MTA (DART) transit-authority tax), the Texas local-rate cap. Texas collects no construction use tax at building-permit issuance; use tax, when owed, is self-assessed by the purchaser and remitted directly to the Comptroller's office rather than collected by a city or county permit office (Comptroller Use Tax guidance, comptroller.texas.gov/taxes/sales/use-tax.php). Under Comptroller guidance for real property repair and remodeling, "Labor to repair, remodel, or restore residential real property is not taxable"; on the lump-sum contract typical of residential re-roofing, "you pay tax on all your supplies, materials, equipment, and taxable services when you buy them. You don't charge your customer tax" (Comptroller Pub. 94-116, Real Property Repair and Remodeling, comptroller.texas.gov/taxes/publications/94-116.php) -- so the combined rate above is the roofer's own cost basis on materials purchased, not a rate charged to the homeowner.
