Florissant homes
About seven in ten Florissant homes were built in the 1950s and 1960s, most of them ranch houses, and only about one in ten dates from 1980 or later.
Old Town is the city’s historic center, and Old St. Ferdinand Shrine, a church built in 1821, is listed on the National Register.
Is it time to replace your roof, siding or windows in Florissant?
About seven in ten Florissant homes were built in the 1950s and 1960s. Whatever your home’s age, here is what wear looks like on its roof, siding and windows.

Signs your roof is wearing out
Florissant’s postwar ranches have had more than one roof, and the decking underneath may be original. Look for sagging between rafters, curling or missing shingles, and leaks at chimneys and vents.

Signs your siding is wearing out
Many ranches got aluminum or vinyl siding decades ago. Aluminum dents and chalks as it fades, and older vinyl turns brittle, cracks and comes loose in high wind.

Signs your windows are wearing out
Original steel or aluminum windows and early replacements run cold and drafty, and double panes from later updates fog between the glass when their seals fail. In Old Town, landmark and historic district homes go before the city’s commission first.

Insurance: some insurers limit coverage on older roofs, so storm damage left unrepaired can cost you later.
Some homeowners wait until there’s a leak, a draft or a cracked panel before calling. A free inspection catches problems before then, and tells you what needs a repair, what needs replacing, and what is still fine.
By era
What to expect from your home
Postwar ranches
The ranches built across Florissant in the 1950s and 1960s are now more than 55 years old. A home that age may have had more than one roof already, so we explain up front what we may find once the old layers come off. Many ranches of this age have plank decking, aluminum or asbestos-cement siding, and lead paint under the trim.
The 1970s and later
Home building in Florissant slowed after the 1970s, so newer homes are a small share of the city. Homes from the 1970s and 1980s often have hardboard siding and early vinyl or aluminum windows. For any of them, we install CertainTeed, Owens Corning, GAF and IKO shingles, James Hardie, LP SmartSide and vinyl siding, and Pella windows.
Old Town historic districts
The Historic Residential and Historic Business districts sit at the center of the city. Exterior renovation of a landmark property, or of a contributing building in the Historic District, is reviewed by the city’s Landmark and Historic District Commission, guided by the Old Town Guidelines.
Building code and permits in Florissant
In Old Town, a Certificate of Appropriateness from the Landmark and Historic District Commission must be issued before the building permit. The guidelines cover roof, window and siding replacement, and vinyl, aluminum and other imitation siding are prohibited on landmark structures. Ordinary maintenance is excluded, and the commission charges no fee.
Florissant has adopted the 2021 International Residential Code with local amendments. Its climate table marks ice shield underlayment as required.
The city’s amended code exempts the removal and installation of exterior coverings from a permit when the work does not interfere with other systems, and it requires new exterior coverings and roofing to match the existing appearance, color, texture and profile. Building permits come from the city’s Building Division in Public Works.
We pull the permits your project needs.
