Roof replacement
A St. Louis roof has to survive two different climates a year: a winter that crosses freezing dozens of times, and a summer that cooks the attic beneath it. Replacing one properly means paying for the details that manage both — and those are exactly the lines a thin quote leaves out.
When replacement is the right call
The signals usually arrive together. Age: a covering past its fifteenth or twentieth year here has earned an evaluation even if nothing has leaked yet. Scatter: loose ridge caps, lifted courses, nail heads telegraphing through, granules collecting in the gutters — the signature of thaw-cycle fatigue rather than any single event, and a sign the material has stopped holding itself together. And repetition: a leak that comes back in a different spot after every patch means the patches are chasing a covering, not fixing one.
The economics turn at the same point. Patching fatigued material buys months — new repairs fail at their edges, where new meets old, within a few more seasons. Once the failures scatter across more than one slope, the per-visit money starts adding up to a meaningful share of a replacement without ever resetting the clock.
What a complete quote includes here
Tear-off stated plainly: how many layers are coming off and what disposal costs. A good share of the region’s postwar housing was re-covered once already, so this replacement often strips to the deck. Decking priced by the sheet — nobody honest quotes a fixed number for wood they have not seen. Valley construction named: open metal valleys shed the canopy debris and the winter refreeze that this region serves up; woven valleys trap both. Flashing replaced, not reused — including counterflashing reset into the mortar joints wherever the roof meets brick, which around here is often.
And a ventilation line, every time. Intake at the soffits, exhaust at the ridge, in balance — it is the least expensive line on the quote and the one that decides how the new covering survives its first July. On the pre-war stock, two more questions belong in writing: the condition of any built-in box gutters, and whether the chimney’s masonry is sound enough to flash against. A bid that answers all of this is comparable; a bid that answers none of it is just a number.
Quick answers
- How long does a roof replacement take in St. Louis?
- Most single-family replacements run one to three days once material is on site — longer for complex rooflines, multiple tear-off layers, decking surprises, or low-slope sections that need membrane work rather than shingles.
- Can a roof be replaced in winter here?
- Often, yes. St. Louis winters oscillate rather than freeze solid, and installers work the mild windows between cold snaps. Shingle sealant strips need warmth to bond, so cold-season installs rely on hand-sealing — worth confirming in the quote.
- Do quotes around St. Louis include permits?
- They should — and the answer depends on the municipality. St. Louis County alone contains dozens of them, each with its own permit and inspection habits. Ask the bidder to name the permit and who files it.
