What we see on Florissant homes
The median house in Florissant was built in 1963, and 76.7% of the housing stock there predates 1970. 23,221 housing units, 66.5% of the occupied ones owner-occupied. That leaves a real share of rented property, and a landlord asks different questions than an owner: what fails soonest, what a tenant will call about. The quote is the same either way. Only 1.4% predates 1940, so most roofs here are on their second covering rather than their first or their fourth.
On a roof from that stretch the first question is how many layers are already up there. Two is common and three happens. Add decking that is still the original, and a ridge vent somebody retrofitted twenty years later and sized by eye, and there are three separate things to price rather than one. The consultation settles which of them actually apply before anyone puts a number on the job.

What the winters do here
The 1991-2020 snowfall normal at St. Louis Lambert International Airport, about 4 miles away, is 16.6 inches a year. That is why the ice-and-water shield at the eaves goes on every roof we do rather than only the ones that ask for it.

Permits and paperwork in Florissant
Permits for work like this in Florissant come from City of Florissant Building Division. Some jobs need one and some do not. We work out which yours is at the consultation, not after the tear-off has started, and we pull it ourselves.
We are licensed and insured. Missouri has no statewide roofing license, because roofing is licensed city by city here, so an Illinois license number would carry no weight on this side of the river and we do not quote one at you. Ask for the certificate and you will have it.
Where we work from, and what is nearby
Florissant, MO sits in St. Louis County, and we serve it from our Greater St. Louis office at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303.
In Florissant that covers 63031, 63033 and 63034. Being outside our published list does not mean we cannot come, so call and we will tell you straight away.
What we can put on a Florissant house
IKO Dynasty for the wind rating and the color blends, IKO Nordic when Class 4 impact is worth having. The shingles are mold, mildew and algae resistant. We carry CertainTeed and GAF as well, so if a subdivision covenant names a product we are not locked out of it. Most roofs get a full tear-off, with ice-and-water shield, synthetic underlayment, new flashing and new drip edge. We never reuse drip edge. Where the deck and the existing layer allow it, an overlay is an option, and we will tell you honestly which one your roof is a candidate for.
There is a showroom at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303. Most people change their mind about a color at least once standing in front of the full-size panel, which is a much cheaper place to do it.
