What we see on Wentzville homes
The median house in Wentzville went up in 2007, and 88.9% of the town was built from 1990 onward. 15,919 housing units, 84.6% of the occupied ones owner-occupied. That is a high share, and it means most of these conversations are with the person who will live with the result rather than with somebody signing off on a property they never see. 38.7% has gone up since 2010, so most of these roofs are still on their first shingle. The useful question here is not replacement, it is whether the flashing and the ridge venting were done properly the first time.
That puts a lot of these roofs at the end of their first cycle rather than their third: one layer of builder-grade three-tab, decking still sound, not much hidden. It is the easy version of this job. It is also the version where stepping up pays, because the shingle being replaced was picked to hit a builder's price, and a Class 4 like IKO Nordic costs less to fit now than it will next time round.

What the winters do here
The 1991-2020 snowfall normal at St. Louis Lambert International Airport, about 27 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 Wentzville
Permits for work like this in Wentzville come from City of Wentzville 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.
Resolution #23-1953, on workmanship, siding repairs and water resistive barriers, is what the City points contractors at for matching: "If a damaged plane or elevation does not have a suitable match, the entire plane or elevation shall be replaced." It covers shingles as well as siding, so a repair that will not match is a conversation to have before the work rather than after it.
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is licensed city by city here, so an Illinois license number would carry no weight on this side of the river and we do not quote one at you.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
Wentzville, MO sits in St. Charles County, and we serve it from our Greater St. Louis office at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303.
In Wentzville that covers 63385. 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 Wentzville 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.
