Roof Replacement Cost Data for St. Louis Homes: What RSMeans Shows

What Roof Replacement Cost Data Covers

RSMeans started with Robert Snow Means, a civil engineer who began documenting construction costs decades ago, and RSMeans reports that its researchers now spend about 25,000 hours a year keeping the numbers current. The online version comes in three tiers, Core, Complete and Complete Plus, each with a different level of detail.

For a roof, the database splits the job into parts you can check line by line:

• Material costs: pricing for asphalt shingles, metal panels, slate and other systems.
• Labor rates: installation, tear-off and repair tasks priced separately.
• Other cost factors: equipment rental, permit fees and debris disposal.

Put in your roof size, slope and material and you get a roof replacement cost breakdown you can hold a contractor’s bid against. Contractors who blend this roofing cost estimate data with their own job history get sharper still, because they can see where past bids ran high or low.

St. Louis Roof Replacement Costs by Roof Size

In St. Louis, MO, a roof replacement typically costs $5,750 to $17,500. Roof size drives most of that spread:

• 1,500 square feet: $5,750 to $7,500
• 2,000 square feet: $8,000 to $10,000
• 2,500 square feet: $10,250 to $12,500
• 3,000 square feet: $12,500 to $15,000
• 3,500 square feet: $14,750 to $17,500

Material changes the picture too. Architectural shingles on a standard three to four bedroom home average $11,200 to $17,100. These are estimates, not quotes, so treat them as a sanity check on the numbers you collect. Our roof replacement page walks through what the work itself involves.

Five Things That Move Your Price

Size and Complexity

Valleys, dormers, gables and skylights all add cut-up work. Two roofs of the same square footage can price differently when one has three slopes and the other has eight.

Material Choice

Asphalt shingles are the most common choice here and can last up to 30 years. Slate costs more and often lasts over 100 years. Metal holds up to wind and humidity, though hail can dent it.

Pitch, Access and the Old Roof

Steep roofs slow crews down and raise labor hours. Tall properties and tight work areas can need extra equipment. Tearing off several old layers adds cost before new material goes on, which is one reason roof repair sometimes makes more sense than replacement.

Local Labor Conditions

ZipRecruiter puts average hourly wages for roofing contractors in the state at $16 to $20, with experienced crews charging more. The U.S. Bureau of Labor Statistics projects roofing employment will grow 6% between 2023 and 2033, so labor demand stays part of the pricing picture here.

Permits and Code

Roofing work has to meet local code, and a permit is required. The City of St. Louis Building Division calculates roofing permit fees on the estimated value of the work, typically $150 to $500. Watch the jurisdiction: St. Louis City and St. Louis County run separate building departments with separate processes, so your address decides where the permit is filed.

Roof Cost Per Square and Commercial Buildings

Roofers quote by the square rather than by the whole roof, so ask any contractor how the roof cost per square was calculated and what it includes. The same approach applies to flat and low-slope buildings. Commercial roof cost data in RSMeans covers membrane systems, tear-off and equipment, which is what our commercial roofing team prices against on larger properties.

What St. Louis Weather Does to the Math

We sit in a hail corridor with hot humid summers and hard freeze-thaw winters, and that wears a roof out faster than a cost table alone suggests. Granules collecting in the gutters, shingles lifted after a cold snap and a ceiling stain under the eaves all point to a roof nearing the end of its life. After a big hail event, demand spikes and so does pricing, which is another reason to have your numbers ready before you start calling. Our residential roofing page covers the systems we install across the region, and roof financing can spread the cost out.

How to Use the Numbers With a Contractor

• Collect several quotes and compare the line items, not just the totals.
• Confirm licensing and insurance before you sign anything.
• Ask for references and photos of finished jobs nearby.
• Check what the workmanship and material warranties actually cover.

Our free inspection includes a digital analysis of the roof, so the estimate you get lines up with what the camera found. We work throughout St. Louis and the surrounding communities.
