GAF Camelot II Designer Shingles: Luxury Slate-Look Specs & Insurance Guide
Published: 2026-07-27
GAF Camelot II is a premium designer shingle engineered to replicate the appearance of natural quarried slate at approximately 20-25% of the installed cost. Part of GAF's Designer Lifetime Shingle line, Camelot II uses a multi-layered fiberglass mat construction with SBS-modified asphalt for enhanced flexibility and impact resistance. The shingle features random tab designs with deep shadow lines that create the dimensional depth characteristic of genuine slate roofing.
Each Camelot II shingle measures 13-1/4 inches by 39-3/8 inches with a 5-5/8-inch exposure, producing 5 layers of coverage at any point on the roof — compared to 2-3 layers for standard architectural shingles. The 340 lbs/square installed weight provides substantial wind resistance without requiring the structural reinforcement that heavier luxury shingles (CertainTeed Grand Manor at 450 lbs/square) may demand. The SBS polymer modification allows the shingle to remain flexible at low temperatures, reducing the cracking risk that conventional asphalt shingles face in cold-weather installations.
Installation Requirements & Wind Warranty
Camelot II requires 6 nails per shingle (not the standard 4) for full wind warranty coverage. When installed as part of a complete GAF Roofing System with required accessories — Starter Strip Shingles, Ridge Cap Shingles, Leak Barrier (WeatherWatch or StormGuard), and Roof Deck Protection (Deck Armor or Tiger Paw) — the system qualifies for the WindProven Limited Wind Warranty with no maximum wind speed limitation. This is the same unlimited wind warranty offered on GAF Timberline HDZ, making Camelot II suitable for hurricane-prone regions including Florida, the Gulf Coast, and the Southeast.
Installed cost for a complete Camelot II system typically runs $8.50-13.00/sq ft including all GAF accessories, underlayment, and tear-off of one existing layer. This positions Camelot II between standard architectural shingles ($4-6/sq ft) and ultra-premium luxury shingles like CertainTeed Grand Manor ($9-14/sq ft). The premium over standard architectural shingles buys: (1) slate-look aesthetics that can increase home value by 3-5%, (2) SBS-modified asphalt for superior cold-weather performance, (3) 5-layer coverage for enhanced water shedding, and (4) the unlimited WindProven warranty.
Insurance & Storm Damage Considerations
Camelot II's SBS-modified asphalt provides measurably better impact resistance than standard oxidized asphalt shingles. While Camelot II does not carry a formal UL 2218 Class 4 impact rating (unlike CertainTeed Grand Manor), the SBS modification reduces the incidence of granule loss and micro-cracking after hail exposure. For insurance claims, the key documentation requirement is the same as all GAF system installations: verify that all required GAF accessories were installed per manufacturer specifications. Missing accessories void the wind warranty and can reduce claim valuation in Xactimate estimates.
For adjusters evaluating Camelot II storm damage claims: the SBS modification makes these shingles less brittle than standard architectural shingles, so impact damage may present differently — look for circular depressions with intact granules rather than the clean fractures typical of standard shingles. The deep shadow lines can mask hail impact marks, so inspections should be conducted with a flashlight at a low angle to highlight depressions. Document the installation date (printed on the shingle wrapper or available from GAF's warranty registration system) — Camelot II shingles manufactured after 2022 use an updated SBS blend with improved UV resistance.

🛡️ Roof Insurance Claim Process (Step-by-Step)
- Document the Damage — Take photos/video of all damage from multiple angles before any tarps or temporary repairs. Include close-ups of impact marks, granule loss, and membrane punctures.
- Prevent Further Damage — Install emergency tarp or temporary seal. Most policies require you to mitigate further damage. Keep receipts for emergency repairs — they are reimbursable.
- File the Claim Promptly — Contact your insurance carrier within 24-72 hours. Provide: date of loss, type of damage (wind/hail/other), photos, and a rough estimate if available.
- Schedule Adjuster Inspection — The carrier sends a claims adjuster. Have your roofing contractor present during inspection — they can point out damage the adjuster might miss, especially on membrane seams and flashings.
- Get Contractor Estimates — Obtain 2-3 estimates from licensed roofing contractors who work with insurance claims. Ensure estimates use Xactimate pricing (industry-standard insurance estimating software).
- Review the Adjuster Report — Compare the adjuster's scope of work with your contractor's estimate. Common disputes: matching undamaged adjacent slopes, code upgrades (building code may require upgrades the adjuster didn't include), and overhead & profit calculation.
- Negotiate if Necessary — If the adjuster's estimate is lower than your contractor's, submit a "supplement" with additional documentation. You have the right to use a public adjuster (typically 10% of claim) if negotiations stall.
- Approve and Schedule — Once you agree on scope and price, the carrier issues an Actual Cash Value (ACV) payment. After replacement, submit the final invoice for the Recoverable Depreciation (RCV - ACV = depreciation held back until work is complete).
📅 Roofing Season Calendar by Region
Plan your roofing project for optimal weather windows. Off-season installs may require special procedures and cost 10-20% more.
| City | Climate Zone | Roofing Season |
|---|---|---|
| Dallas TX | 2A (Hot-Humid) | March-November (peak: April-June, September-October) |
| San Antonio TX | 2A (Hot-Humid) | March-November (peak: April-June, September-October) |
| Houston TX | 2A (Hot-Humid) | Year-round (avoid peak hurricane season June-November for major projects) |
| Chicago IL | 5A (Cold-Humid) | April-October (peak: June-August). Winter installs require special adhesive and heat sources. |
| Phoenix AZ | 1B (Very Hot-Dry) | Year-round (avoid July-August peak heat for worker safety). Peak season: October-April. |
| Denver CO | 4B (Mixed-Dry) | April-October (peak: June-August). Hail damage repairs spike June-July. |
| Atlanta GA | 3A (Warm-Humid) | March-November (peak: May-July, September-October) |

Frequently Asked Questions
How does GAF Camelot II compare to CertainTeed Grand Manor?
Camelot II: 340 lbs/square, SBS-modified asphalt, slate-look, unlimited wind warranty with GAF system, no formal UL 2218 impact rating. Grand Manor: 450 lbs/square, standard oxidized asphalt, slate-look, 150 mph wind rating with 6-nail installation, UL 2218 Class 4 impact rating. Camelot II is lighter (better for older roof structures), more flexible in cold weather, and carries GAF's unlimited wind warranty. Grand Manor is heavier (better wind resistance through mass), has formal Class 4 impact certification (insurance discounts in hail regions), and carries a 15-year non-prorated warranty period vs. Camelot II's 10-year. Price is comparable — both are premium products at $8.50-14/sq ft installed.
Is Camelot II eligible for the WindProven Limited Wind Warranty with no maximum wind speed?
Yes — when installed as part of a complete GAF Roofing System with all required accessories (Starter Strip Shingles, Ridge Cap Shingles, Leak Barrier, and Roof Deck Protection), using 6 nails per shingle, the WindProven Limited Wind Warranty applies with no maximum wind speed limitation. This is the same warranty offered on GAF Timberline HDZ. Partial installations with non-GAF accessories do not qualify. The warranty requires GAF-certified installation and registration with GAF's Golden Pledge or System Plus warranty program.

Commercial Roofing Specifications — Engineering Guide
TPO (Thermoplastic Polyolefin) is the dominant single-ply membrane for commercial low-slope roofing. Its white reflective surface meets energy codes and reduces cooling loads by 15-30% compared to dark roofs. TPO is a blend of polypropylene and ethylene-propylene rubber, typically reinforced with a polyester scrim for dimensional stability. Key manufacturers include Carlisle, Firestone, and Johns Manville.
ASTM D6878 (TPO Spec), FM 4470 (Wind Uplift), UL 790 (Fire), ASTM E108 (Fire), Title 24 (CA Cool Roof)
TPO membrane thickness (45, 60, 80, or 90 mil) should be selected based on the project's wind uplift requirements and hail exposure. 60 mil is the commercial minimum for most applications. 80-90 mil is recommended for high-wind zones (FM 1-120+) and regions with hail risk.
