What you're paying for with roof replacement
What's included: full tear-off to the deck, deck inspection and re-nailing, ice-and-water at eaves and valleys, synthetic underlayment, new drip edge, starter course, architectural shingle, ridge and intake ventilation balanced as a system.
If we open things up and find rot in the decking, we stop and show you before replacing anything. No surprise line items appearing on the final invoice.
O'Fallon specifics
ZIPs 63366, 63368, in St. Charles County. Housing is one of the fastest-built cities in the metro, with roofs from 1998 to 2012 aging out on the same schedule, so roof replacement here means whole neighborhoods reaching 20 years at once more often than not.
Storm exposure: wide open western exposure, so hail hits with nothing to slow it down. We document it accordingly.

Roof replacement in O'Fallon - common questions
Do you actually cover O'Fallon?
Yes - O'Fallon is regular territory for us.
What warranty comes with it?
A lifetime workmanship warranty from us, plus whatever the manufacturer covers on the materials. Being an Owens Corning Platinum Preferred Contractor lets us write their stronger system warranties, which most contractors can't.
How do I know the damage is real and not a sales pitch?
You get the photographs. Every slope, with the problems circled. Take them to another contractor if you want a second opinion - we'd rather you were sure.
What does roof replacement cost in O'Fallon?
It depends on the size of the roof, the pitch, how many layers come off and what the deck looks like underneath. We won't guess a number over the phone and we won't quote a price per square that changes once we're on site. The inspection and the written estimate are free, so you'll have a real figure before you commit to anything.
Do you offer financing?
We do, and we'll walk through the options with you when we give you the estimate. Plenty of roofs get replaced because the alternative is interior damage that costs more than the roof.
