Residential Roof Repair in St. Louis, MO

Flashing failures at chimneys, skylights, dormers, and sidewall intersections cause the majority of roof leaks in the St. Louis market. The counterflashing that overlaps the base flashing cracks or separates; the base flashing that wraps the chimney or sidewall pulls away from the mortar joint; the step flashing at a shed dormer corrodes or was installed incorrectly in the first place. Flashing replacement is surgical work — and it is work that a simple shingle patch does not address.

Storm damage repair — missing shingles, lifted tabs, creased shingle fields from hail, and dented or cracked vent boots — typically follows a significant weather event. St. Louis spring and summer storm seasons produce multiple repair-triggering events per year. If the damage is insurance-covered, Revolve documents to insurer standards during the same inspection visit.

Vent boot failures are disproportionately common relative to their size. The rubber boot that seals around a pipe penetration through the roof cracks with UV exposure and age — typically at 10–15 years on asphalt-backed boots — and creates a small but steady leak path. Replacing the boot is a one-hour repair that, if ignored, produces water damage over a much larger ceiling area.

Not every repair request results in a repair recommendation. If the roof is over 20 years old, shows widespread granule loss across multiple slopes, and the repair area is large enough that the cost approaches a meaningful fraction of replacement cost, replacement is often the better financial decision. Revolve will tell you that, with the math behind it, at the inspection — not after the repair bill has been written.

The break-even analysis is straightforward: compare the repair cost against the remaining service life of the existing roof and the carrying cost of deferred replacement. A $1,200 repair on a roof with two to three years of service life left is a poor investment relative to replacement. A $400 flashing repair on a 12-year-old roof with adequate deck condition and 8+ years of service life remaining is exactly right.

Active leaks are an emergency. Water intrusion that reaches insulation, framing, or interior finishes creates secondary damage — mold risk, drywall replacement, structural softening — that far exceeds the repair cost. Revolve's goal is same-day emergency tarping for active leaks and full repair scheduling within the week for non-emergency damage.

After major storm events in the St. Louis area, demand for repair services spikes and scheduling windows extend. We prioritize active leaks and structural damage. Minor storm damage without active water intrusion can typically wait for a scheduled repair appointment without immediate consequence, provided the damaged area is not creating an entry point during subsequent rain events.
