Slate and synthetic slate roofs in Dallas
A slate roof outlives everyone who installs it, provided the nails and flashings under it are done right. Composite slate gets the same look at a third of the weight and is rated for Dallas hail.

Quick answer
Slate roofing in Dallas comes two ways: natural quarried slate hung on copper nails over a deck built to carry it, and synthetic slate molded from polymer composite that weighs a quarter as much and carries a Class 4 impact rating. We install both, repair broken slates, and re-hang slipped ones without disturbing the sound slates around them.
The job
Natural or synthetic: how the choice usually goes
Natural slate belongs on the Tudor and Colonial Revival homes along Swiss Avenue and on any house framed for it. It weighs eight to ten pounds a square foot, so a home framed for shingles needs an engineer before it can carry it. Old slate roofs fail at the fasteners and flashings long before the stone.
Synthetic slate from DaVinci, Brava or CertainTeed gives the same profile at about two pounds a square foot, installs on ordinary decking, and is tested to UL 2218 Class 4 for hail.

Budget
What a slate roof costs to install in Dallas
Slate is the top of the roofing price range.
Published Dallas figures put tile and synthetic slate at roughly $10-$20 per sq ft. That is a planning range from published Dallas market data, not a quote, and your roof size, pitch, layers and decking condition move it either way.
- Natural versus synthetic
Quarried stone, freight and copper cost the most; composite lands well below.
- Framing capacity
Natural slate on a shingle-framed home may need an engineer and added rafters.
- Flashing metal
Copper valleys and step flashing are a real share of a natural slate job.
- Roof complexity
Dormers, hips and turrets mean more cutting and more metal.
- Repair scope
A dozen re-hung slates is a half-day; a slope with new flashing is a week.
- Historic review
Landmark districts may require a specific material or profile.
- Tear-off
Old slate is heavy to haul and worth salvaging when sound.
Your options
Natural slate or synthetic slate
Weight, hail and budget decide it. Here is how the two compare on a Dallas roof.
| Compare | Natural slate | Synthetic slate |
|---|---|---|
| Weight per square foot | 8 to 10 lb, needs framing sized for it | About 2 lb, standard framing |
| Hail performance | Can crack under 2 inch hail; slates replaceable | UL 2218 Class 4, insurer discounts common |
| Life and warranty | 75 to 150 years on copper fasteners | 50-year limited warranty typical |
Natural slate
Quarried slate is graded by expected life, S1 at seventy-five years and up down to S3 at twenty. We source Vermont or Virginia slate for matching repairs, Spanish or Brazilian stock for a full new roof at lower cost. Every slate hangs on two copper or stainless nails driven to hold, not tight, so the stone can move. Headlap, exposure and the slater's hook for repairs are the details that decide whether the roof lasts a century or leaks in ten years.
Composite slate
Synthetic slate tiles are molded from polymer or rubber with the cleft face of real stone and come in graduated widths so the courses look random. They cut with a knife, nail through a marked line, and carry a Class 4 impact rating that many Texas insurers discount for. Weight is close to an architectural shingle, so no framing upgrade is needed. Colors run from solid slate gray to blended weathered mixes, and a 50-year limited manufacturer warranty is typical.
Slate repair and re-hanging
A slipped or broken slate is pulled with a ripper that cuts the old nails, a new slate is slid into place, and it is held with a copper hook or a nail through the joint above covered by a copper bib. We never face-nail or caulk a slate; both fail within a few seasons. Repairs also mean walking the roof correctly, on ladders and hooks rather than on the stone, because a careless step breaks more slates than the storm did.
Copper and flashing details
Slate roofs fail at the metal first. Valleys, step flashing at dormers, chimney counterflashing and ridge and hip caps are the pieces that rust out or were replaced with galvanized steel by a previous roofer. We rebuild these in 16 or 20 ounce copper, soldered where they need to be, with the slates lifted and re-hung around them. On a synthetic roof the same details go in with painted aluminum or copper, whichever the budget and the look call for.
Roofing in Dallas
What we see on Dallas roofs
Swiss Avenue and the rest of the Munger Place addition in East Dallas were built between the 1900s and 1920s in Prairie, Colonial Revival and Tudor styles, and many of those roughly 200 homes still carry original slate. Because the district is a designated Dallas landmark, a re-roof there is reviewed for material and appearance, so we scope a matching repair or an approved synthetic profile before pricing it.

Slate roofing questions from Dallas homeowners
Natural slate on copper runs 75 to 150 years; synthetic carries a 50-year limited warranty.
Only if it was framed for it or an engineer signs off; most shingle-framed homes suit synthetic.
From the street, no. Molded cleft faces and mixed widths read as stone.
Natural slate can crack under large hail. Synthetic is rated UL 2218 Class 4, the highest impact class.
Yes. Individual slates are replaced with hooks or copper bibs without touching the rest of the roof.
No. We work from ladders and hooks, because foot traffic breaks slate.

Policies vary between like-kind slate and a shingle equivalent; we document what is there for the claim.
