Shingle brands
CertainTeed, GAF and Owens Corning, compared honestly
We install all three. This page says what differs between them, which certification we hold with each, and, just as importantly, what those certifications do not mean. Every one of them is checkable on the manufacturer's own website, and we link to ours.
CertainTeed
We install Landmark, Landmark PRO and Patriot
What we install on most roofs now. Landmark is the line our color previews are built from, so what you pick on this site is what we order.
- Landmark is a laminated architectural shingle: two layers bonded together, which is where the shadow line and the dimensional look come from.
- Landmark PRO is the heavier version of the same shingle. Patriot sits below both and is the value option in the range.
- Ten Landmark colors are previewed on this site, from Moire Black through Heather Blend and Resawn Shake.
CertainTeed ShingleMaster
A credential CertainTeed issues to a contractor after it has reviewed the business: licensing, insurance and workmanship standards. It is the qualification that lets us offer CertainTeed's extended warranty coverage on a qualifying system.

We install Timberline HDZ and Timberline Natural Shadow
The brand behind most of the roofs already in our project gallery, and still what we install where a homeowner asks for it by name.
- Timberline HDZ is GAF's architectural shingle and the one our proposals price by default.
- Natural Shadow is the lighter-profile shingle in the same family, with a smaller color range.
- GAF is the largest roofing manufacturer in North America, which in practice means the widest local supply and the easiest color match years later.
GAF Certified Contractor
A credential GAF issues after vetting a contractor's licensing, insurance and standing. It is what allows us to register GAF's enhanced warranties on a qualifying system.

We install Duration, Oakridge and Supreme
Installed on request, and the brand most often specified by insurance carriers and builders who have standardized on it.
- Duration is the architectural shingle in the range and the one most comparable to Landmark and Timberline HDZ.
- Oakridge sits below it, and Supreme is the three-tab shingle: a single layer, flat-looking, and the shortest-lived of the three.
- All three share the same core color names locally, which is why this site lists them under one Owens Corning heading rather than three.

Why we will not tell you one brand is best
Installed correctly, by a crew that flashes the penetrations properly and does not skip the starter course, all three of these shingles will outlast most of the roofs around them. Installed badly, so will none of them.
That is not a dodge. Manufacturer warranties cover manufacturing defects. The overwhelming majority of roof failures we are called out to are not defects: they are workmanship, usually at a valley, a pipe boot or a wall intersection. Which is why the certification matters more than the badge on the bundle, and why we publish both of ours.
What these are worth to you
GAF and CertainTeed each reviewed this business, its licensing, its insurance and how it installs, before issuing the credential it put next to our name. That is what lets us register their extended warranties on a qualifying roof. Owens Corning's contractor network brings us their training and product support on the systems we install for them.
