On This Project
Civic buildings have to last on the day they need to.
We approach civic work the way we approach hospitals and historic landmarks. The roof is not finished when the membrane is down. It is finished when the flashing details, the warranty paperwork, and the maintenance plan are walked through with the building owner. That is the standard our crews work to. It is also why most of our work comes from owners we have already roofed for.
“You only see a roof twice. The day you sign for it, and the day it lets you down. We make sure that is two different decades.”

We hire roofers, foremen, sheet metal installers, and service technicians. Most of the people on our crews have been here for years. Pay is competitive, the work is steady, and the trucks leave from Onalaska.

If a building of yours is on this list, the conversation is short.
We work from a one-page scope walk, a measured site visit, and a written estimate within the week. Phone is fastest: 608.783.2106, option 2. Email works too.
