Ready to talk about your slate roof? Reach out and we will schedule a course-by-course inspection built specifically for historic St. Louis homes like yours. We will follow up with a detailed written scope and honest pricing you can use.
Slate roofing in St. Louis is a craft trade, not a general roofing job, and the century-old mansions across Lafayette Square, Compton Heights, and Holly Hills prove exactly why homeowners protect it. The original Vermont and Buckingham slate on these homes has weathered 100+ Missouri winters, freeze-thaw cycles, and hail-heavy summers, and can keep going another full lifetime when the copper flashing, ridge slates, and fasteners are properly restored. At Top Quality Exteriors, our crews approach every slate roof as the historic asset it truly is.
Our approach favors preservation over replacement wherever it’s viable: individual slate swaps with matched stock, copper flashing renewal at valleys and chimneys, and full re-slating only when the original material has passed its service life. For homes carrying terracotta or clay accents, we coordinate closely with our tile roofing in St. Louis team so ridge lines, dormers, and hip caps stay period-correct. Every scope is documented with photos and city permit details before any work begins.
Natural slate on a St. Louis home is a system, not just a roof covering — and every part of that system reacts to Missouri weather. S1-grade Vermont and Buckingham slate has an expected service life of 100 to 150 years, but the copper valleys, ridge saddles, and step flashing that sit between the slates typically age faster and are usually what causes leaks, not the slate itself. Freeze-thaw cycles work moisture into hairline delamination, hail from the March-through-June corridor can crack individual slates, and windblown limbs off older oaks around Tower Grove Park and Forest Park chip corners over decades. Our crews inspect every course with the same care as the field, replace failed slates with grade-matched stock, and rebuild copper details with lead-tin solder joints where the original craftsmen used them. For homeowners weighing synthetic options like Davinci, EcoStar, or Brava, we walk through the trade-offs honestly on the front end.

Slate work moves slower than asphalt, and it should. Every project starts with a course-by-course survey, a permit review with the City Building Division, and a written scope that spells out which slates come off and which stay. Here’s how we run it.
We walk your slate roof, hatch to ridge, and check every field slate, ridge saddle, and copper detail. Failures on city homes sit at wall junctions. Photos come with your report.
You get a written scope by course, slate grade, and flashing metal. Line-item pricing lets you pick repair, partial re-slate, or full restoration — no pressure. Permits are listed.
We pull the roof permit through the City of St. Louis Building Division on your behalf. Historic homes get Preservation Board sign-off first. Turnaround runs one to three days.
Our crew stages replacement slates from graded stock, then rebuilds copper valleys and ridge caps. Old slate hooks and nails come out cleanly so decking stays sound. Fit by hand.
We walk the finished roof with you and hand off documentation: permit, photos, slate origin, and workmanship warranty. Punch-list items close before we leave. Files stay on record.
Top Quality Exteriors was founded in 2022, and our owner brings more than seven years of industry experience running slate and specialty roof work. That matters here because most slate roofs in the St. Louis city footprint sit on properties older than 90 years — Lafayette Square Victorians, Compton Heights mansions, Holly Hills homes — where a wrong nail size or flashing gauge can shorten a roof’s life by decades. We hire slaters, not general roofers.
We’re a BBB Accredited Business with an A+ rating, licensed in Missouri and Illinois, and carry general liability and workers’ compensation insurance. Our workmanship warranty runs 36 months as a firm baseline, with extended coverage available depending on the material system. As an Owens Corning Preferred Contractor on the asphalt side, we hold the same documentation discipline on slate: measurable, permit-tracked, photo-verified from tear-off to closeout.
Slate is the highest-ticket item in residential roofing — expect a full St. Louis slate project to open at $40,000 and climb from there based on square footage, pitch, and copper spend. Repair-only work on an existing slate roof can land between $2,500 and $8,000 when the copper valleys are already sound. Synthetic slate systems from Davinci, EcoStar, or Brava usually deliver an authentic historic look at roughly one-third to one-half the cost of quarried stone.
The math shifts once you take a 30-year view. A 100-plus-year natural slate roof outlasts three or four asphalt replacements, and it holds appraisal value on historic-district properties near Lafayette Park and Tower Grove that comparable asphalt does not. Missouri carriers usually cover storm-damaged slate at RCV when the coverage is written for the material, so a repair supplement after a hail event can move a five-figure claim without a premium change.
Every credential we carry is a commitment to quality, safety, and your peace of mind — on every project, in every state we serve.
