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.
Should the tear-off expose rot in the decking, we stop and show you before replacing a single board. 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.
