Key facts for hiring a roofer in St. Louis

How to get written quotes on one scope

St. Louis has an old housing stock: 100,811 of its 174,111 housing units were built in 1939 or earlier (Census ACS 2020-2024; read 17 October 2026). Those are house ages, not roof ages. If you want an inspection before you ask for quotes, ask the inspector to write down the covering, the number of layers, the deck type and any soft or rotted areas, and attach that report to your scope so every quote starts from the same findings.

Your written scope for a roofing job in St. Louis

In St. Louis, 75.5% of housing units were built in 1959 or earlier and 7.7% in 2000 or later (Census ACS 2020-2024; read 17 October 2026). On an older house, boards or sheathing under the old roof may need replacing once it is torn off. Ask each quote to state how much sheathing it expects to replace, the price per sheet or board for more, and how hidden damage will be shown to you before extra work starts.

Roof covering, roof area and how many layers come off
If your home was built before 1980, ask how damaged decking is handled
Who pulls the St. Louis permit for roof replacement (not like material, or more than 25% sheathing replaced), and when the inspection is booked
Removal and disposal of the old parts or materials
Warranty terms on parts and labor, in writing
