Impact-resistant roofing
Not required — Lamar Municipal Code Chapter 6, Building Regulations, Article II (Minimum Standards Codes) read in full -- all 9 divisions covering the adopted Building, Electrical, Mechanical, Plumbing, Fire, Residential, and Fuel Gas Codes plus Administration, alongside Articles I, III (Asbestos Control), IV (Shipping Containers), and V (Vacant Commercial Buildings) -- contains no provision addressing impact-resistant roofing, UL 2218, Class 4 shingles, or hail.
