What we see on St. Charles homes
St. Charles's median house dates from 1986, which puts most of the town in the build-out between 1970 and 1990. 32,204 housing units, 67.9% 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. 13% has been built since 2010, so a fair number of these are original builder units reaching the age where the glass seal goes before anything else does.
The seventies and eighties are where the first generation of vinyl siding and aluminum-clad windows shows up, and both are now well past what they were built for. Vinyl from that era goes chalky and brittle: it cracks when a ladder leans on it instead of flexing. The windows fail differently. The sealed unit fogs while the frame still looks perfectly sound, which is why people put up with them for years longer than they need to. On siding specifically the layer count decides the day: one layer comes off cleanly, two means the sheathing has not seen daylight in thirty years.

Permits and paperwork in St. Charles
In St. Charles, work like this is permitted through City of St. Charles Community Development, Building Division. Whether yours needs a permit is a question of scope, and it gets answered before anyone starts. Pulling it is our job. So is being on site when the inspector comes.
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is licensed city by city here, so an Illinois license number would carry no weight on this side of the river and we do not quote one at you.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.

What we can put on a St. Charles house
All of it is Alside: Coventry and Odyssey Plus vinyl, Board N Batten for a vertical look, and Ascend Composite for the look of real wood. Profile and color are the two big decisions, and each line has its own range of both. Soffit, fascia and trim are part of the same job rather than an extra line.
There is a showroom at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303. Color on a screen is not color in daylight, and a sample chip is not a panel, so it is worth the drive before you commit to either.
