What we see on Waterloo homes
The median house in Waterloo went up in 1991, and 51.9% of the town was built from 1990 onward. 4,651 housing units, 76.9% of the occupied ones owner-occupied. Mostly owners, then, which usually means the decision turns on how long you plan to stay rather than on what it does to a rent roll. 15.2% has been built since 2010, so a good share of these roofs are still on their first shingle, where how well the flashing and venting were done matters more than wear.
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 the Belleville SIU research station, about 20 miles away, is 11.2 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.

What we can put on a Waterloo 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.
You can see all of it at our showroom, 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303.
