You know your slate roof needs someone who’s done the actual work before, not a general roofer guessing at it. Call (314) 618-8888 or send a message and we’ll come out, walk the roof, and hand you a written report before quoting a dime.
A slate roof on an older north St. Louis County home is one of the few covers that outlasts everyone who’s touched it, but only when the crew doing the work actually knows slate. If you own one of the pre-1939 homes off Woodson Road, you’ve probably watched general roofers try to patch a leak with asphalt cement and watched the same leak come back after the next hard rain. At Top Quality Exteriors, we treat slate roofing in Overland the way the material demands — matched pieces, hidden copper valleys, and hand-cut work done right the first time.
Slate isn’t the workhorse cover for this town, and most Overland homes wear asphalt over 1940s-era plank decking. But the older housing stock still holds real slate, and matching a hundred-year-old tile takes sourcing and skill few crews carry. We hand-cut and hook individual slates back into a field, rebuild the ridge and rake with lead-coated copper, and reset snow guards along the eaves. For post-war ranches where slate was never in play, our residential roofing in Overland workflow fits better.
Slate is a specialist trade — S1 grade Vermont slate lasts 100 years and Buckingham can push 200, but every install detail matters. On the older Overland stock near Woodson Road and Lackland Road, most slate roofs we see are 80 to 110 years old, with the original zinc flashing pitted through and copper valleys eaten thin. We source matched replacement slates by color, size, and grade, then hand-cut each piece and hook it back into the field so the repair disappears from the ground. During the May 16, 2025 hail event that dropped ice across Overland and Charlack, older slate covers held up better than asphalt, but the cover isn’t the whole story. What fails first is the flashing at chimneys, valleys, and dormers, and that’s where a real slate crew earns the job. We rebuild those transitions in 16-ounce copper, replace deteriorated underlayment, and reset snow guards. If you’d rather explore a different premium cover, our metal roofing in Overland page walks through standing-seam options that suit these older homes well.
Slate work is unlike any other roofing job — you don’t hurry it, and you don’t fake it. Here’s how we walk through a slate repair or restoration on an older Overland home, from the first look up through the final ridge cap detail.
We climb the roof and log every slope and flashing detail. Broken slates get marked with grid position on the photos. You get a full written report before we quote the actual work.
Matching a 90-year-old slate takes patience. We pull Vermont and Buckingham stock and hand-select each piece by eye. Nothing gets ordered until the batch blends in on the roof.
Most slate leaks trace to failed flashing, not the slate. We rebuild valleys, chimney counter-flashing, and step flashing in copper. It outlasts every cover above it on the roof.
Where iron nails have rusted through, we use stainless slate hooks to secure new pieces. The hook holds from below and stays invisible from ground. It preserves the original look.
We photograph every completed section and walk you through the repair. Snow guards get reset, gutters cleared, and the yard swept twice. You get a workmanship warranty in writing.
Top Quality Exteriors was founded in 2022, and the team carries over 7 years of industry experience across roofing and siding work throughout north St. Louis County. We’re a BBB Accredited Business with an A+ rating, licensed in Missouri and Illinois, and we carry general liability plus workers’ comp on every crew that shows up in Overland. Ask to see the paperwork on any slate quote — one uninsured worker on a 12/12 pitch changes your life.
Slate roofing isn’t a job we hand off to a subcontractor. Owner Mario Granados walks every slate project personally, and the crew doing the hand-cut work knows S1 from S3 grade by weight alone. We back our workmanship with a firm 36-month warranty on every job and extended terms up to a Lifetime warranty on selected products. If you’re comparing quotes across north St. Louis County, ask each contractor where their copper is coming from — the answer tells you plenty.
Slate isn’t the cheapest cover you can put on an Overland home — never has been, never will be. A partial slate repair on an older cape typically runs $2,500 to $8,000 depending on how many pieces need replacement and whether the flashing has to come out at the same time. Full slate restoration on a pre-1939 home starts around $25,000 and can push past $60,000 when copper valleys, ridges, and chimney flashing all get rebuilt from scratch on one pass.
That said, slate outlasts three or four asphalt tear-offs, which is the math that keeps older homes on slate for a hundred years or more. On a working-family budget we can walk through Hearth or GreenSky financing to spread the cost out. For newer post-war homes where slate was never a fit, our tile roofing in Overland page covers concrete and synthetic tile as a heavier alternative.
