CertainTeed Highland Slate roofing typically costs about $650-$1,050 per roofing square installed, where one square covers 100 square feet. A common 2,000-square-foot roof may total roughly $14,000-$23,000 after waste, tear-off, and standard installation; roof pitch, local labor, and product availability affect the quote.
Highland Slate may be harder to find than current CertainTeed lines, so confirm that a supplier can provide the exact product and color before budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed roofing | $650 per square | $825 per square | $1,050 per square | Standard access and typical tear-off |
| Materials | $250 per square | $350 per square | $475 per square | Shingles and common roof accessories |
| 2,000-square-foot roof | $14,000 | $18,000 | $23,000 | About 22 squares with waste |
Installed Highland Slate pricing by roof size
Roofers price shingles in squares, not by the home’s interior floor area. The estimate below assumes a moderately pitched roof, standard installation, about 10% waste, and removal of one existing asphalt layer. Complex roofs or expensive metro-area labor can exceed the high end.
| Roof area | Estimated squares with waste | Low total | Average total | High total |
|---|---|---|---|---|
| 1,500 sq ft | About 17 | $11,050 | $14,025 | $17,850 |
| 2,000 sq ft | About 22 | $14,300 | $18,150 | $23,100 |
| 2,500 sq ft | About 28 | $18,200 | $23,100 | $29,400 |
Assumptions: U.S. midmarket labor, standard underlayment, one-layer tear-off, and ordinary roof access. The roof’s measured surface area—not its living area—determines the number of squares.
What shingles, labor, and tear-off add to the quote
A written estimate should separate the shingle package from installation and site work. Material prices vary with inventory, color, freight, and whether Highland Slate is available as new stock or only through remaining inventory. Ask the contractor to identify the exact product rather than substituting a similar-looking CertainTeed line without approval.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| Shingles and roofing materials | $250-$475 per square | Product availability, underlayment, starter and ridge pieces |
| Installation labor | $200-$350 per square | Pitch, roof height, cutting, and crew access |
| Tear-off and disposal | $50-$100 per square | Number of existing layers and dump fees |
| Flashing and ventilation work | $300-$1,500 per project | Chimneys, valleys, vents, and code needs |
| Decking repairs | $75-$150 per sheet | Rot, water damage, and local material rates |
Roofing labor can also be quoted by square; hourly labor commonly works out to about $50-$90 per worker-hour when estimated separately. Compare the included tear-off, flashing, and disposal scope before judging two totals.
How roof pitch, waste, and decking change the total
Roof geometry affects both material use and installation time. A simple roof may need about 8%-10% extra shingles for cuts, while multiple hips, valleys, dormers, or steep slopes can raise waste to roughly 12%-18%. On a 22-square order, that difference can mean several additional bundles and more cutting labor.
Pitch also changes access requirements: a roof steeper than 6:12 often needs additional safety setup, and slopes around 8:12 or higher can add roughly 10%-25% to labor, depending on height and layout. Decking replacement is usually discovered after tear-off, so a quote may list it as an allowance rather than a fixed quantity.
Ask for the measured roof squares, waste percentage, pitch adjustment, and per-sheet decking rate in writing.
How long Highland Slate installation takes
A straightforward 20-25-square roof often takes a crew of four or five about two to four working days, including tear-off and cleanup. Smaller crews, steep sections, rain delays, or extensive flashing work can extend the schedule. A one-day installation is possible on a simple roof with a larger crew, but speed alone does not confirm that the scope is complete.
For labor comparison, a typical project may involve roughly 80-160 worker-hours, depending on crew size and roof complexity. Confirm whether the schedule includes removal, underlayment, cleanup, and final inspection.
When removal and roof repairs raise project costs
Removing a second shingle layer can add about $40-$90 per square, while extensive rotten decking, damaged fascia, or chimney flashing can add hundreds or several thousand dollars. Difficult access, limited driveway space, or long distances to disposal facilities may also increase hauling charges. These expenses are separate from the Highland Slate shingle price.
Before work begins, ask how concealed damage will be documented and whether repairs require approval above a stated dollar limit. A detailed quote should also name the disposal method and explain whether old flashing will be reused or replaced.
Agree on unit prices for hidden repairs so unexpected work can be priced consistently.
How regional labor rates shift Highland Slate estimates
Roof replacement prices can vary by roughly 10%-20% between lower-cost rural markets and high-cost metro areas. Coastal cities and regions with high insurance, disposal, or labor expenses may run 15%-30% above a typical national estimate. Local snow, wind, or fire-code requirements can also affect underlayment, fastening, ventilation, and inspection costs.
These are broad comparisons, not fixed regional rates. Highland Slate’s availability may be more important than geography: limited stock can raise freight expense or make an exact match impractical. Compare local bids only after confirming that each includes the same shingle, quantity, and code-related work.
Ways to control the Highland Slate roof budget
Request at least three itemized bids using the same roof measurements and product specification. If Highland Slate is unavailable, compare an approved substitute by appearance, warranty, weight, and full installed price rather than choosing by bundle cost alone. A lower material quote may not include starter shingles, ridge caps, flashing, or delivery.
Keeping sound flashing or decking may reduce cost only when the contractor confirms that reuse meets manufacturer instructions and local code. Scheduling outside the busiest storm-repair periods can improve contractor availability, but weather and crew calendars vary by region. Avoid paying for unnecessary upgrades that do not address the roof’s condition or local requirements.
Scope consistency and confirmed product supply are the strongest controllable ways to avoid surprise costs.
