On Des Peres' 1960s-70s homes along the Manchester Road and I-270 corridors, a full tear-off is usually preferred. These roofs show aging flashing and valley wear after each storm season, and stripping to the deck lets the crew inspect sheathing and re-flash properly rather than burying it. Overlays add weight to aged structures. Your matched pro checks the existing layer count, which code typically caps, and inspects the decking before recommending scope. On Des Peres' mature stock in a stable neighborhood worth holding long-term, a clean tear-off is the sound choice.

When a Des Peres roof ages out, homeowners often weigh impact-rated or designer shingles for a long-term hold in a stable neighborhood. Architectural asphalt shingles are the durable baseline; class 4 impact-rated products add hail resilience after West County seasons and may carry insurance-premium considerations worth raising with your carrier. The matched contractor can quote standard architectural alongside impact-rated or designer options so you weigh upfront cost against the longer hold these upgrades offer for a home you plan to keep.

A complete replacement addresses what is under the shingles. After tear-off the crew inspects decking for rot, replaces failing sheets (per-sheet pricing), and installs new synthetic underlayment, ice-and-water shield, fresh flashing and boots — addressing the aging flashing and valley wear common on these homes — and corrected ventilation. On 1960s-70s stock, aged decking is a real possibility, only confirmable once exposed. Ask your matched pro how decking replacement is priced so the quote reflects the actual condition of your Des Peres roof once the old layer is off.

Permitting runs through the City of Des Peres, since Missouri has no statewide contractor license; your matched pro pulls the permit. Expect a manufacturer's shingle warranty (extended when the installer is certified, and designer or impact-rated products often carry strong terms) plus a contractor workmanship warranty on the install, both written into the quote. For a long-term-hold home, the workmanship warranty matters — correct flashing and decking detail, not the shingle brand, is what keeps the replacement watertight over the decades you plan to stay.

Once flashing and valley wear become widespread or the roof has been patched repeatedly, a full replacement — often with a designer or impact-rated upgrade for a long-term hold — is the sounder spend than another repair. Age, extent of wear, and how long you plan to stay decide it. Your matched pro inspects the whole roof, documents any storm damage for an insurance claim, and gives you an honest read on whether a repair still works or a Des Peres replacement is the right long-term move.
