What we see on Alton homes
The median house in Alton was built in 1953, and 73.9% of the housing stock there predates 1970. 12,513 housing units, 57.1% of the occupied ones owner-occupied, which is a lower share than most of the towns we cover. A good deal of what we look at here is a rental or a recent purchase, and in both cases the useful question is what has to be done now against what can wait. 27.6% of it predates 1940, and on a roof that usually means a steeper pitch, board decking rather than plywood, and at least one layer somebody added instead of tore off.
On a roof from that stretch the first question is how many layers are already up there. Two is common and three happens. Add decking that is still the original, and a ridge vent somebody retrofitted twenty years later and sized by eye, and there are three separate things to price rather than one. The consultation settles which of them actually apply before anyone puts a number on the job.

What the winters do here
The 1991-2020 snowfall normal at St. Louis Lambert International Airport, about 16 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 Alton

What we can put on an Alton 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. 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.
