Not sure of the pitch? Most ranch homes sit low; a roof you cannot walk on, such as 9/12 and up, adds safety gear and labor. This page starts Missouri at 5/12.
Our model puts a new asphalt roof in St. Louis, MO at $10,320 to $15,720, based on a typical 1,840 sq. ft. single-story house. The job we priced has 20.8 squares of roofing (2,079 sq. ft.) on a 5/12 slope; removing one existing layer, labor and materials are all counted.

Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the St. Louis, MO estimates above.
The Line Items Behind a St. Louis, MO Roofing Bid
When two quotes for the same house are far apart, the gap is usually scope. Here is what each common variable is worth on the 20.8-square roof above:
- Old shingles. Removing the existing layer accounts for about $3,020 of the price. A hidden second layer adds roughly $1,960 more.
- Geometry. Four-sided hip roofs run about $1,250 above a gable; heavily cut-up roofs with dormers sit about $2,100 above it.
- Height. A second story adds roughly $900 to the same roof, because every bundle goes higher and safety setup takes longer.
- Skylights. Swapping or adding a skylight costs around $370 each at St. Louis, MO rates.
- Bad wood. Damaged decking is the most common mid-job extra. Agree on a price per sheet before work starts.
- Flashing, vents and gutters. Some roofers include new flashing and vents; others bill them separately. Price new gutters on their own with the gutter cost calculator.
- Permit and disposal. Fees depend on the town. Confirm the bid includes both the permit and the dumpster.

How Missouri Weather Ages a Roof
Averages for Missouri: summer highs around 90°F, winter highs around 40°F, winter lows around 22°F. The map below files it under Region 3. The weather above points to a few specific risks for Missouri roofs.
Hail. Storms here regularly bruise shingles and dent metal. Impact-resistant shingles cost more, but many insurers lower premiums for them - ask your agent before you choose.
Cold snaps. Repeated freezing and thawing pries at nail holes, seams and flashing. Ask for ice barrier along the eaves and new flashing everywhere the roof meets a wall.
Gusts. Thunderstorm winds find any loose tab. Ask which wind rating the shingle carries and whether the crew will use the enhanced nailing pattern.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Missouri is Region 3. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Is Metal Worth It in St. Louis, MO?
Metal roofs come in a few families, and they do different jobs. The prices below are for a typical 1,840 sq. ft. single-story house in St. Louis, MO.
- Standing seam: $29,580 to $45,090. One panel covers the whole run from the ridge down to the gutter, so water has almost no joints to find. Roofers like it on low pitches and simple gables. The premium over architectural shingles here is roughly $22,100.
- Steel shingles: $22,190 to $33,820. Aluminum shingles: $24,540 to $37,400. If the neighbors would frown at ribbed panels, this is the answer. From the curb they read as shingles or shake. Aluminum is lighter and never rusts; steel costs less and takes a hailstone better.
- Stone-coated steel: $30,210 to $46,040. Steel tiles with a coat of stone granules. They are quiet in the rain, hard to dent, and look like tile or shake from the street.
- Copper: custom quote only. A copper roof is hand work by a sheet-metal specialist, and it is priced far above standing seam. It never needs paint and weathers to a green patina. Few homes cover the whole roof with it; dormers and entry roofs are the usual places.
Ice dams are the bigger risk, and metal stops most of them by shedding snow before it can refreeze. A reflective finish then helps through the hot weeks; copper weathers dark and does not.
Hail marks show most on thin, smooth panels. A heavier gauge, a textured finish or a stone coat keeps them out of sight. Owners who stay put get the most from metal, because the long service life is where the savings sit. Want a firmer metal number? Try the metal roof calculator with your measurements.

Best Season for a New Roof in St. Louis, MO
Roofing goes on most of the year in Missouri. Mild shoulder seasons are ideal; after a big storm, crews book up fast.
After a big storm, out-of-area crews go door to door. Before signing, confirm liability and workers' compensation insurance, a local address, and any license your state or town requires.
Pricing Low-Slope Roofs in St. Louis, MO
A flat roof the size of this home's 1,840 sq. ft. footprint would run, in St. Louis, MO:
- EPDM rubber: $15,240 to $19,790. Synthetic rubber, usually black, laid in wide sheets with glued or taped seams. It shrugs off hail and hard frost and is easy to patch, so it suits garages, porches and roofs nobody sees.
- TPO, 60-mil: $13,110 to $17,030. It goes down in sheets that the crew fuses together with a hot-air gun, so there are no glued seams to fail. A common pick when the flat roof sits over a bedroom or a kitchen.
- PVC, 60-mil: $15,860 to $20,590. The premium white membrane: welded seams, a strong fire rating, and good resistance to puddles and chemicals. It fits roofs that carry foot traffic or hold water after a storm.
Price order in St. Louis, MO: TPO first, PVC last, with EPDM between them. These figures assume polyiso insulation and one layer removed. Small roofs carry a premium because setup is the same for any size. Ponding water is the main enemy of flat roofs through a Missouri winter. Ask for tapered insulation at low spots and clear drains. Run the flat roof calculator to match a specific membrane and drain layout.
Plan for winter first: welded seams and clear drains. A white membrane is still worth it over rooms that get hot in July.

Roof Replacement FAQ: St. Louis, MO
What permits does a Missouri roofing job need?
In most places, a complete replacement needs a permit and may need an inspection. Your roofer should apply for it; a request that you do it yourself is a warning sign.
How do roofers measure a roof in squares?
Roofers measure surface, not floor area. The 1,840 sq. ft. footprint in this guide turns into about 2,079 sq. ft. of roof at 5/12 - 20.8 squares. Different counts between bids are a red flag.
How many working days does a new roof need?
Expect a short job for 20.8 squares of shingles - often a day or two, sometimes more. The crew should tarp or dry-in anything they open before leaving.
Is an old roof covered by my insurer?
Only for sudden damage such as wind, hail or a falling tree, never for plain wear. Certain policies cover an aging roof at its depreciated worth rather than full replacement. On a roof that costs $10,320 to $15,720 to replace, that gap is large, so check your settlement terms. In Missouri, also check the wind and hail deductible - many policies set it as a percentage of the home's insured value.

Quick Answers
Answers use Missouri averages; energy prices updated October 2026.
What time of year is best for a new roof in Missouri?
Almost any month. Winter highs near 40°F and summer highs near 90°F rarely halt a job in Missouri, so schedule around your plans and ahead of storm season.
Does a new roof in Missouri need an ice barrier membrane?
In much of Missouri, yes. Winter lows around 22°F bring regular freeze-thaw, and colder, higher areas see ice dams. At minimum, put it in valleys and at roof-to-wall joints.
Does metal roofing make sense in Missouri?
It depends on how long you stay. Metal costs more now and lasts much longer; Missouri weather (winter lows near 22°F, summer highs near 90°F) favors neither choice, so compare cost per year of service.
Will a lighter roof lower cooling costs in Missouri?
Somewhat. With summer highs near 90°F and power at 16.8¢ per kWh (national average 21.7¢), a lighter roof trims AC use; pair it with good attic ventilation.
Can new shingles go on top of the old roof?
Sometimes, if only one layer is on now and local code allows a second. A full tear-off costs more but exposes the deck, so rotted boards get replaced rather than buried.
