On Carondelet's 1800s and early-1900s riverside brick homes, tear-off frequently reveals what a drive-by estimate misses — multiple old shingle layers, aged plank decking, and box gutters that need rebuilding. River-corridor exposure can also weather the flashing harder. Your matched verified contractor scopes from an actual on-roof inspection so the quote reflects these realities up front, rather than a low number that grows mid-project once the old roof is off. The matched contractor assesses the whole roof on a Carondelet home, not just the obvious spot, so the replacement reflects the real condition and you are told honestly what the roof does and does not need.

Most are tear-offs. Older Carondelet homes often carry layered roofing over plank decking, and overlaying again hides decking condition and stops the crew from re-flashing chimneys and rebuilding box gutters. A tear-off starts from a clean, inspected deck. Your matched pro confirms on-site whether your structure and City of St. Louis code would permit any overlay, but on this aged riverfront stock a full tear-off is usually the sound, lasting choice. Your matched Carondelet pro confirms on-site whether your specific structure and City of St. Louis code would even permit an overlay, but on this housing stock a full tear-off that starts from a clean, inspected deck is usually the durable, lasting choice.

Architectural (dimensional) asphalt shingles are the common choice on Carondelet's pitched roofs — longer warranties and better wind resistance than three-tab, which matters given river-corridor exposure — while any flat or low-slope sections take a membrane. Your matched contractor can quote the appropriate system for your roof and discuss impact-rated options, so you weigh upfront cost against expected lifespan rather than receiving a single fixed estimate. Your matched contractor can quote standard architectural shingles alongside an impact-rated or premium option for your Carondelet roof, so you compare upfront cost against expected lifespan rather than receiving a single take-it-or-leave-it number.

Permitting runs through the City of St. Louis — your matched pro pulls it, since Missouri has no statewide contractor license. Warranty includes the manufacturer's material coverage (longer with a certified installer) and the contractor's workmanship warranty. Ask for both in writing on the quote. On older stock where box gutters and chimney flashing are rebuilt, the workmanship coverage on those details is especially worth confirming. Get the material warranty and the contractor's workmanship warranty for your Carondelet replacement in writing on the quote, since the workmanship coverage is what protects the install itself on a multi-decade investment.

When tear-off would reveal failing decking, the shingle field is broadly worn, or box gutters and flashing keep leaking despite patches — repeated repairs stop pencilling out. Your matched verified pro assesses the whole roof on-site and tells you honestly whether a targeted repair still makes sense or whether a replacement is the better long-term investment. You are under no obligation after the assessment. The matched contractor assesses the whole roof on a Carondelet home, not just the obvious spot, so the replacement reflects the real condition and you are told honestly what the roof does and does not need.
