How Much Does a New Roof Cost in Franklin County, MO?

There is no honest way to quote a roof from a price chart, but there is an honest way to set your expectations before a contractor ever climbs your ladder. This guide gives you the real Franklin County numbers, the seven factors that move them, and the questions that separate a written estimate you can trust from a driveway guess you cannot. Emmendorfer Exteriors has put roofs on right around 2,400 Missouri homes since 1990, including 306 jobs in 2025, so the ranges below come from work we actually do here, not a national average pulled off the internet.

Roof pricing in eastern Missouri is shaped by one thing flatlands never deal with: the storm stack. Spring and summer hail and straight-line wind bruise the shingles, then a hard winter of freeze-thaw works the seams and flashing, then the next year's hail finds the gap. The March 14-15, 2025 storm system that put Franklin County under a federal disaster declaration brought large hail, tornadoes, and straight-line winds over 75 mph across eastern Missouri. A roof that survives that pattern for fifteen or twenty years has usually taken hidden damage in the wood underneath, which is why the deck condition matters as much to your price as the shingle on top.

For a straight asphalt shingle replacement on a typical Franklin County home, plan on roughly $6,400 to $13,500 installed, which works out to about $425 to $750 per square. A square is 100 square feet of roof surface, and most single-family homes here run 15 to 30 squares once you account for pitch and waste. These are directional figures for a full tear-off with new underlayment, not a quote. The only number that means anything is the written estimate a contractor hands you after walking your actual roof.

The wide spread is real, not vague. A simple, walkable, single-story ranch in a Union subdivision with one layer to tear off sits at the low end. A steep, cut-up two-story near the Washington riverfront with two old layers, dormers, and rotten decking found on tear-off sits at the high end, on the same square footage. Pitch, complexity, layers, and hidden wood are what move you across that range, and none of them show up in a satellite measurement.

If hail or wind caused the damage, your homeowner policy often covers a repair or full replacement, and your out-of-pocket cost drops to your deductible rather than the full roof price. That is why so many Franklin County roofs get replaced on a claim after a storm season rather than out of pocket. Tom Emmendorfer documents the damage, files the claim, and meets your adjuster on the roof to make sure the approved scope matches what the storm actually did.

Two honest cautions. First, under Missouri Revised Statute 407.725 no roofer can legally pay, rebate, or waive your deductible, so anyone who offers to is breaking the law and you should be wary of the rest of their quote. Second, a claim does not make the roof free. You still owe your deductible, and any upgrade you choose beyond like-for-like, such as moving from standard architectural to Class 4 impact-resistant, is usually an out-of-pocket difference. We walk you through both numbers before you decide.
