The short list
| Factor | Why it moves the price | What to ask |
|---|---|---|
| Material and grade | Natural slate, clay tile, concrete tile, copper, standing seam steel and Enviroshake differ a lot in material cost and install labor; within slate, grade and quarry matter | Exact product, grade (S1 for slate), color and profile |
| Roof complexity | Hips, valleys, dormers, turrets, curves and wall intersections multiply cutting, flashing and labor | How the bid accounts for each feature |
| Pitch and height | Steep, tall roofs need staging, harnesses, lifts and slower work | Access and safety plan |
| Tear-off and disposal | Removing an old slate or tile roof is heavy, slow work with heavy disposal | Number of layers and disposal included |
| Deck and structure | Slate and clay tile are heavy; switching from a lighter roof can need a structural review and framing work | Whether a structural check is needed, and who does it |
| Underlayment | High-temperature membranes under metal and tile, and doubled layers on low slopes, add cost and life | Underlayment product and coverage |
| Flashing metal | Copper flashing lasts as long as slate and tile but costs more than painted steel | Flashing metal named for valleys, walls and chimneys |
| Metal gauge and panel length | 24 gauge costs more than 26; one-piece panels avoid end laps | Gauge, finish system, and whether panels are formed to length |
| Matching existing work | Matching a discontinued shingle, tile or slate means sourcing salvage or a close match | How the match was found, with a sample |
| Gutters, trim and accents | Copper or half-round gutters, chimney caps and decorative trim add up | What's included vs. optional |
| Approvals and permits | HOA submittals, historic review and city permits take time and paperwork | Who handles approvals and pulls the permit |
| Warranty | Higher manufacturer warranty tiers can require specific accessories | Exact manufacturer and workmanship warranty terms |
Material by material
Natural slate
Slate grade and quarry drive material cost, and slate is installed by hand, piece by piece, with copper or stainless nails and copper flashings. Thickness and size change both weight and labor. Most of a slate bid is skilled labor. See slate roofing, slate quarries and brands and, for a lighter option, synthetic vs. real slate.
Clay and concrete tile
Clay usually costs more than concrete, and barrel profiles take more labor and more pieces at hips and ridges than flat tile. Tile is heavy, so the structure matters, and on a reroof the underlayment is often what's being replaced while sound tile is reset. See tile roofing, clay, concrete and tile reset.
Standing seam
Panel profile (snap-lock vs. mechanically seamed), gauge, paint system, and the number of hips, valleys and penetrations drive a standing seam price. We form standing seam and R-panel/PBR in 24 or 26 gauge steel on our own roll formers, cut to the measured length of each run. Metal lead time is typically 1 to 2 weeks. Our standing seam cost guide covers metal in more detail.
Enviroshake and synthetic shake
Composite shake is lighter than slate or tile, so structure is rarely an issue, and it installs more like a traditional shake. Profile, color blend and accessories (hip and ridge, starter) move the price. We are certified with Enviroshake. See Enviroshake roofing and synthetic roofing.
Copper
Copper weight, seam type (soldered flat seam is labor-intensive), the shape of the feature and the copper market drive the cost. See copper roofing and accents.
Costs people forget
- Decking repairs found during tear-off (a good bid states a per-sheet price)
- Chimney, skylight and wall flashing upgrades
- Gutters removed and reinstalled, or replaced to match
- Landscaping, driveway and pool protection on estate lots
- Permits and HOA or historic review time
Insurance can change the math
Texas insurers must offer a premium credit for UL 2218 impact-rated roofs, but each company sets its own amount, and Class 4 earns the largest. We can't promise a discount; ask your insurer for their figure in writing. After a qualifying install we fill out TDI Form PC068 for you. Many slate-look, shake-look and metal products carry Class 4 ratings. If a storm damaged your roof, your policy, not the material, decides what's covered; in Texas you generally have 1 year from the date of loss to file, so check your policy. We document damage with photos and can meet your adjuster, but we don't adjust or negotiate claims.
Reading two bids side by side
- Same product, grade, color and profile on both?
- Same underlayment and flashing metal?
- Tear-off, disposal and decking allowance spelled out?
- Gutters, trim, chimney caps and accents included the same way?
- Same warranty, from the manufacturer and the contractor, in writing?
- Who handles HOA approval, permits and inspections?
If those match, the bids are comparable. If they don't, the cheaper bid usually left something out. Every inspection comes with a free digital photo report, so you see what we see.
