Walk the streets in Westlake and you see a lot of steep hip roofs on stone and stucco homes. Many owners want the depth of slate without the weight and cost of real stone. One product I get asked about for those homes is CertainTeed Grand Manor.
I’m Blake Snow. I’ve been roofing for 30 years, and Snow Roofing & Exteriors is certified with CertainTeed. Here’s what CertainTeed itself publishes about Grand Manor, and what I check before I put it on a Westlake bid.
What Grand Manor is
CertainTeed’s Grand Manor product data sheet calls it “the super heavyweight of laminated shingles.” Each shingle is two full-size, one-piece base layers with random tabs and shadow lines, built to give deep, natural-looking dimension.
| Spec | Grand Manor (CertainTeed) |
|---|---|
| Overall size | 18” × 36” |
| Weather exposure | 8” |
| Shingles per square | 50 |
| Approx. weight per square | 418 lb |
| Impact rating | UL 2218 Class 4 (product page) |
| Fire rating | Class A |
| Minimum slope | 2” per foot (best look at 9” per foot or steeper) |
That 418 lb per square matters. On a 50-square Westlake roof you’re carrying about 20,900 lb of shingles alone. Most homes built for a heavyweight shingle handle it fine, but I always check the decking and framing, and I won’t lay it over an old roof.
The warranty, in CertainTeed’s words
From CertainTeed’s product page and the Grand Manor limited warranty:
- Lifetime limited transferable warranty for residential owners. CertainTeed defines lifetime as “for as long as the original individual property owner owns the property.”
- 50-year limited transferable warranty for group-owned or commercial property.
- 10-year SureStart protection period, CertainTeed’s non-prorated early coverage.
- 30-year StreakFighter algae-resistance warranty.
- 15-year, 110 mph wind warranty, upgradable to 130 mph with CertainTeed starter and CertainTeed hip and ridge.
Like every shingle warranty, it covers manufacturing defects, not hail. That’s an insurance question, not a warranty one.
What most Grand Manor articles skip
Most pages about Grand Manor stop at “it’s thick and pretty.” Here’s what actually decides whether a Westlake Grand Manor roof looks right and lasts:
- Layout on steep hips. Grand Manor’s random tabs look best when the crew plans the coursing across every hip and dormer, not when they start each slope blind. Bad layout shows from the street.
- Matching accessories. The 130 mph wind upgrade needs CertainTeed starter and hip and ridge. I put the exact accessory names on the bid so nobody swaps them on install day.
- Valleys and wall flashing. On a stone and stucco home, the metal work at walls, chimneys and valleys is where leaks start. Ask how each one will be flashed, and in what metal.
- Ventilation. CertainTeed’s warranty limits coverage on inadequately ventilated decks. A real intake and exhaust plan belongs in the quote.
- HOA submittals. Westlake and Southlake committees usually want the color name and a real sample board, not a phone photo.
Grand Manor vs. other CertainTeed premium lines
If Grand Manor isn’t quite the look, CertainTeed’s other luxury shingles are worth a look too. We cover Presidential Shake for a wood-shake look and Belmont for a different slate-look profile. If you want real slate or a synthetic, our designer and luxury shingles page lays out the options. For impact ratings across brands, see Class 4 impact-resistant shingles.
Already have Grand Manor and storm damage?
Get each slope photographed, and identify the exact color before anyone scopes a repair. Our storm damage page walks through what to document. In Texas you generally have one year from the date of loss to file a claim, but check your policy.
