Colleyville has plenty of stone and brick homes where a basic architectural shingle looks out of place, but natural slate isn’t in the budget or the framing. That’s where GAF’s slate-look designer shingles come in, and the two I’m asked to compare most are Slateline and Camelot II.
I’m Blake Snow. I’ve been roofing for 30 years, and we’re certified with GAF. Here’s an honest side-by-side using GAF’s own data sheets, both dated April 2026, plus what matters on a Colleyville roof.
Side-by-side from GAF’s data sheets

How they look on a Colleyville house
- Slateline has the bigger shingle and oversized tabs. From the street, it reads as a bolder, more regular slate pattern with strong shadow lines. I think it suits colonial, traditional brick and simpler rooflines where you want a clean slate look.
- Camelot II uses a shorter shingle with more pieces per square and a dimensional, artisan-cut look. It reads as more traditional and old-world. I think it suits stone homes, steep French or Tudor-style roofs and houses with lots of dormers.
Both are part of GAF’s Designer line. GAF calls each one “affordable luxury” at a fraction of the cost of traditional slate or wood shake. Neither is real slate, and I won’t pretend either one looks identical to stone up close. Our slate- and shake-look shingles page shows where they sit against synthetic and natural slate.
Same ratings, same warranty structure
On paper, the two shingles carry the same ratings and the same warranty structure:
- Class 4 impact: both pass UL 2218 with a Class 4 rating, but only packages bearing the Class 4 statement are rated. Check the bundle wrapper on delivery day.
- Wind: both are warranted for winds up to 130 mph for 15 years with special installation and GAF Starter Strip Shingles.
- Warranty: a Lifetime limited transferable warranty with Smart Choice Protection (non-prorated material and installation labor) for the first 10 years, on qualifying installations. “Lifetime” means as long as the original individual owner (or an eligible second owner) of a single-family home owns it.
- Algae: a 25-year StainGuard Plus algae warranty, only on packages bearing that logo.
The hail fine print (important in Colleyville)
Both GAF data sheets say the same thing: GAF makes no express or implied warranty about impact performance against hail, and hail damage is not covered under the limited warranty. A Class 4 rating may help with your insurance carrier, so ask your agent whether your policy gives a discount for it. But hail damage is still an insurance claim, not a GAF warranty claim. Our Class 4 shingles page and best Class 4 shingles for Texas guide explain more.
Repairs: don’t mix them
Because Slateline is about 40 inches long and Camelot II about 34 ½ inches, with different tab shapes, you can’t patch one with the other on the same roof plane. The tabs and joints won’t line up. Repairs should use the same product and color, ideally from a close lot.
If your roof is the older, original Camelot (not Camelot II), GAF said in 2015 that the old and redesigned Camelot may not be mixed. Our post on GAF Camelot vs. Camelot II matching covers that.
Which I’d pick for your roof
- Choose Slateline if you like a bolder, cleaner slate pattern, your roof has long, simple planes, or your HOA approves a slate look with strong shadow lines.
- Choose Camelot II if you want a more traditional, dimensional slate look, have a steep or cut-up roof with dormers and turrets, or want the TimberCrest ridge option.
- Step up to synthetic or natural slate if the house calls for it. See our Colleyville slate roofing page.
Either way, I’d use GAF’s matching hip and ridge, starter and accessories so the roof qualifies for GAF’s system warranty coverage.
HOA tips for Colleyville
Many Colleyville neighborhoods have deed restrictions or HOA design review for roof color and style. Before you sign:
- Get the HOA’s approved shingle list or color rules in writing.
- Submit the exact product and color name with GAF’s data sheet.
- Look at full-size shingles in daylight, not just a brochure. GAF says printed colors aren’t accurate.
We bring full-size samples of both for your review.

After a storm
Get the roof inspected and documented before anyone patches it, and keep a leftover bundle or the wrapper if you have one, since it shows the product, color and Class 4 label. In Texas you generally have 1 year from the date of loss to file a claim, but check your policy. Our storm damage page explains the process.
