O’Fallon homes
About six in ten O’Fallon homes were built in 1990 or later, the 2000s busiest of all, and only about one in twenty predates 1940.
The city itself is much older than most of its houses. It began in 1854 around a B&O railroad depot, and Scott Air Force Base is about five miles away.
Is it time to replace your roof, siding or windows in O’Fallon?
About 62 percent of O’Fallon’s homes were built in 1990 or later, and the median home dates to 1997. Whatever your home’s age, here is what wear looks like on its roof, siding and windows.
Signs your roof is wearing out
Many O’Fallon homes from the 1990s and 2000s still have their original roof, and others are on their first replacement. Look for grit in the gutters from lost granules, and shingles that lift or blow off in high wind.

Signs your siding is wearing out
Vinyl from the 1990s and 2000s fades on sunny walls, cracks in hail and cold snaps, and can warp near grills. Mildew streaks on shaded walls are common too.

Signs your windows are wearing out
Builder-grade windows from the 1990s and 2000s often fog between the panes as their seals fail, and rooms get drafty as weatherstripping wears.

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
Homes built before 1990
About 38 percent of O’Fallon’s homes predate 1990, including a small number from before 1940. Homes this age have had at least one replacement roof, so the inspection looks at how the last one was installed as well as its condition.
The 1990s
Homes from the 1990s make up about 17 percent of the city. Many have already had one replacement roof, and others still have their first. The free inspection shows where yours stands.
The 2000s
Nearly a quarter of O’Fallon’s homes were built in the 2000s, more than in any other decade. Some still have their original roof, siding and windows from the same years.
The 2010s
Nearly another fifth of the city’s homes date from the 2010s. Newer homes rarely need a full replacement unless hail has hit them, and hail damage is hard to see from the ground.
Permits and code in O’Fallon
O’Fallon builds to the 2018 International Residential Code, and permits and inspections come from the Building and Inspections Division of the city’s Community Development Department.
The city’s amendments to that code do not change its rules for roofs, siding or windows. Your project manager confirms with the city which permits your project needs before work begins.
We pull the permits your project needs.

Questions from O’Fallon homeowners
My O’Fallon house was built in the 2000s. Does it need a new roof?
Not necessarily. Age is one factor, but condition decides it. Our free inspection includes photos so you can see what we see, and when a repair is the right answer, we say so.
Do I need approval from O’Fallon’s Historic Preservation Commission to replace my roof?
The commission, set up under City Code Chapter 151, recommends landmark designations to the City Council and holds hearings on proposed and designated landmarks. If your home is a designated landmark, check with Community Development at 618-624-4500 ext. 4 before exterior work begins.
