Baseline costs by material
Standard three-tab or architectural asphalt shingles remain the most common choice in St Louis, running roughly $4.50 to $8 per square foot installed depending on tear-off complexity. A typical 2,000 square foot roof replacement lands between $9,500 and $16,500.
Standing-seam metal roofing costs more upfront, typically $12 to $18 per square foot, but is increasingly requested in the region for its hail resistance, which can matter given the metro's hail frequency.
What adds cost in city neighborhoods
Steep roof pitches on homes in Compton Heights, Central West End, and Lafayette Square require steep-slope labor rates and additional fall-protection setup, adding 15-30% over a simple gable roof.
Multiple dormers, chimneys, and roof planes on Victorian and craftsman homes increase flashing work and labor hours. Narrow city lots with alley-only access can also limit dumpster placement and staging, adding logistics costs.
Tear-off versus overlay
The City of St Louis Building Division and most manufacturer warranties require full tear-off rather than a second layer over old shingles once a roof already has two layers. Tear-off adds $1 to $2 per square foot for disposal but is standard practice in the city given the age of most housing stock.
For slate or wood-shake roofs, tear-off is more labor-intensive and disposal often requires specialized handling, which is why slate roof replacement in St Louis runs $35,000 to $75,000 depending on square footage and slate grade.
Permit and inspection costs
A residential roofing permit through the Building Division of the Department of Public Safety, applied for via stlcitypermits.com or in person at 1520 Market Street, typically adds a modest fee to the project and requires a final inspection before the job is considered complete.
Homes in local historic districts may need additional review time from the Cultural Resources Office if the replacement changes visible roofing material on a street-facing elevation.
Getting accurate bids
Ask each bidder for the same scope: tear-off layers, underlayment type, ice-and-water shield extent, flashing replacement, and ventilation upgrades. Bids that vary by more than 20% usually differ in scope, not just price.
Confirm the contractor holds a current City of St Louis Construction Industry Contractor Graduated Business License and carries liability insurance before signing.

How long does a roof replacement take?

Is metal roofing worth it in St Louis given the hail risk?

Can I add a second layer of shingles instead of a full tear-off?
Only if the roof currently has a single layer; most manufacturer warranties and standard practice in the city call for full tear-off given the age of existing roofs.
