O’Fallon homes

Is it time to replace your roof, siding or windows in O’Fallon?
About six in ten O’Fallon homes were built in the 1990s and 2000s. Whatever your home’s age, here is what wear looks like on its roof, siding and windows.
Signs your roof is wearing out
Most O’Fallon homes from the 1990s and 2000s are on their original roof or first replacement. As shingles age, granules wash into the gutters and the sealant strips let go, so shingles lift or blow off in high wind.

Signs your siding is wearing out
Builder-grade vinyl from the city’s growth years fades, cracks in hail and cold, and pulls loose at the seams. Mildew streaks on shaded walls are common too.

Signs your windows are wearing out
Windows from the 1990s and 2000s are reaching the age when seals fail, so glass fogs between the panes, rooms get drafty and sashes stick.

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
The 1990s
Nearly a third of O’Fallon homes were built in the 1990s, a decade in which the city’s population more than doubled. Builder-grade shingles from the 1990s are at or past their rated life, and many of these homes are due for their first replacement roof.
The 2000s
Almost as many homes were built in the 2000s, as the city added more than 30,000 residents. Builder-grade vinyl windows from these years often fog between the panes as their seals fail, and many roofs are nearing their first replacement.
Since 2010
About one in five O’Fallon homes is newer than 2010, and some are still on their original roof. When a repair is the right answer rather than a replacement, we will tell you.
Building code and permits in O’Fallon
O’Fallon has adopted the 2021 International Residential Code with local amendments. The city’s climate table marks ice barrier underlayment as not required. We still recommend it for most homes.
Where code does not require ice and water shield, an insurer may decline to pay for it, and the cost can fall to the homeowner. We explain this before work begins, so you can decide with the full picture.
O’Fallon’s amended code exempts two common jobs from a building permit: re-roofing an asphalt shingle roof, and replacing doors and windows when the opening size does not change. Siding is not on the exempt list. Permits come from the city’s Building Division, and the city notes that the separate fire districts serving O’Fallon may require their own permits.
We pull the permits your project needs.

Questions from O’Fallon homeowners
Do I need a permit to replace my roof in O’Fallon, MO?
Not for an asphalt shingle roof. O’Fallon’s amended code exempts re-roofing of asphalt shingle roofs from a building permit. Siding is not exempt, and your fire district may have its own requirements.
Does O’Fallon require ice and water shield on a new roof?
No. The city’s amended building code marks ice barrier underlayment as not required. We still recommend it, and we explain before work begins what that can mean if your roof is part of an insurance claim.
Does O’Fallon’s historic preservation commission review roof or siding replacement?
Generally not. The commission’s certificate of appropriateness is required only to demolish a designated landmark or to remove a significant exterior feature named in its designating ordinance.
