TAMKO vs GAF cost depends on shingle line, roof size, tear-off needs, and local labor; installed architectural shingles commonly run about $450-$850 per roofing square, or 100 square feet. For a typical 2,000-square-foot roof surface, many homeowners should budget roughly $9,000-$17,000, with premium products and complex roofs costing more.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| TAMKO architectural shingles installed | $450 per square | $600 per square | $750 per square | Standard tear-off and installation |
| GAF architectural shingles installed | $500 per square | $675 per square | $850 per square | Commonly priced higher for premium lines |
| 2,000-square-foot roof | $9,000 | $12,500 | $17,000 | About 20-22 squares including waste |
| Shingles only | $100 per square | $150 per square | $220 per square | Varies by product and retailer |
Assumptions: U.S. asphalt-shingle roof, standard architectural products, accessible roof, and ordinary removal conditions. Actual bids depend on measured roof area and local rates.
What TAMKO and GAF roofs typically cost per square
For a standard architectural-shingle replacement, TAMKO is often the lower-cost option, while GAF’s comparable products may carry a modest material premium. Installed prices commonly fall around $450-$750 per square for TAMKO and $500-$850 for GAF. A roofing square means 100 square feet of roof surface; waste and cuts are usually included in the contractor’s quantity.
For a straightforward roof, the brand difference is usually smaller than labor, tear-off, and roof complexity. A 20-square roof might price at about $9,000-$15,000 with TAMKO or $10,000-$17,000 with GAF. These estimates assume architectural shingles, standard underlayment, and no major deck repairs. Basic three-tab products can cost less, and premium impact-resistant or designer shingles can raise the total substantially.
Where shingle, labor, and tear-off charges appear
A written estimate should separate the brand and model from installation tasks. Comparing only the shingle material price can be misleading because underlayment, flashing, disposal, and crew labor often account for a large share of the bill.
| Quote item | TAMKO range | GAF range | Typical basis |
|---|---|---|---|
| Architectural shingles | $100-$190 per square | $120-$220 per square | Material, product line, color |
| Installation labor | $200-$350 per square | $200-$350 per square | Roof pitch and crew access |
| Underlayment and starter materials | $30-$80 per square | $30-$80 per square | Product specification and coverage |
| Tear-off and disposal | $50-$150 per square | $50-$150 per square | Existing layers and landfill fees |
| Flashing, vents, and small repairs | $200-$1,500 total | $200-$1,500 total | Scope found during inspection |
Ask each bidder to price the same scope, including removal, underlayment, flashing, ventilation, and cleanup. Labor pricing can be represented as ; roofing crews may charge an effective $50-$100 per worker-hour, although bids are commonly quoted per project or square.
How roof pitch, layers, and shingle grade change the quote
Roof geometry can matter more than the manufacturer. A simple single-story roof with a pitch below 6:12 is generally less labor-intensive than a steep roof above 8:12, which may require extra fall protection and slower installation. Multiple valleys, dormers, skylights, and cut-up roof sections increase labor and waste.
Every extra tear-off layer and difficult roof feature can narrow the apparent price gap between brands. Removing a second existing layer may add roughly $30-$80 per square. A damaged deck can add about $2-$6 per square foot for replacement, depending on plywood thickness and local labor. Moving from standard architectural shingles to impact-resistant products may add $40-$120 or more per square for materials.
Roof size also changes the total: a 12-square garage roof and a 30-square house roof cannot be compared by total price alone. Ask whether the estimate includes a waste allowance, commonly around 10%-15%, and confirm that both contractors used the same measured roof area.
How to lower a TAMKO or GAF installation bid
Keep the scope focused on the roof’s actual needs. If the existing deck is sound and local code allows it, avoid paying for unnecessary sheathing replacement or upgrades that do not address a documented problem. Confirm whether a second layer must be removed rather than assuming the lowest quote includes full tear-off.
Compare complete, matching bids instead of selecting a brand from the shingle price alone. Request the exact product line, quantity, underlayment, flashing plan, ventilation work, disposal fee, and labor warranty in writing. Scheduling outside peak storm-repair periods may improve contractor availability, though weather and regional demand can limit savings. Check whether a bundle price includes required accessories rather than treating them as free.
Do regional labor rates outweigh the brand price gap?
Often they do. Roof replacement in high-cost coastal metros can run roughly 15%-30% above a typical national-market quote, while some rural areas may be 5%-15% lower if crews and disposal are readily available. These are broad comparisons, not guaranteed local discounts; insurance rules, permit requirements, and travel distance can shift bids.
Local labor and disposal charges can outweigh a $20-$50-per-square material difference. In storm-prone areas, demand can rise sharply after hail or wind events, and emergency work may carry rush pricing. Ask whether the quote includes permit fees; where separately billed, common permit charges can range from about $100-$500, with higher amounts possible in major cities.
Which warranty terms are included in each brand quote?
Manufacturer coverage depends on the specific product, registration, installation method, and whether required companion products are used. TAMKO and GAF both offer different warranty terms across product families, so a brand name alone does not establish equivalent coverage. The contractor’s workmanship warranty is separate and may be limited to a stated number of years.
Compare the written warranty conditions and installer coverage, not just the advertised term. Ask who handles a claim, what workmanship is covered, whether wind coverage has limits, and whether installation must meet a manufacturer’s system requirements. A higher quote may include upgraded underlayment or flashing, but those additions should be itemized to show their value.
Three roof quotes show the practical price difference
A 16-square, simple ranch roof with TAMKO architectural shingles, one-layer tear-off, and standard accessories might total about $8,000-$10,500. That works out to roughly $500-$655 per square, assuming no deck repairs and ordinary access.
On a like-for-like job, product choice usually changes the total less than roof scope does. A 22-square home with GAF architectural shingles, moderate pitch, tear-off, and upgraded underlayment might run $12,000-$16,500, or about $545-$750 per square. A steep 28-square roof with multiple valleys, premium shingles, and deck repairs could reach $20,000-$28,000, regardless of whether the bid uses TAMKO or GAF.
Use examples as screening ranges, not fixed offers. The final estimate should identify measured squares, waste, removal layers, material model, labor scope, and any allowances for hidden damage. A quote that is far below competing bids may omit disposal, flashing, or a workmanship warranty.
