Certainteed Landmark all day long. 6 nails per shingle.

SwiftStart starter strips

Drip edge

Shadow Ridge or Cedar Crest hip and ridge.

RoofRunner or Supply house brand synthetic underlayment

GAF Stormguard for valley liner (unless you are getting an extended Certainteed warranty in which case everything must be CT branded)

3 n 1 pipe flashing or bullet boots if you have squirrels

Make sure your roofer has CT certification (I'm Select ShingleMaster, but he needs certs to offer extended warranty if you need or want that)

This is a Class III rated IR shingle. (So is the Tamko XT)

My personal experience is that I feel the granules on CT Landmark are finer and shed less during install. However, Most manufacturers state that granule loss is normal and they overcoat them so it may not make a real difference.

If you are in San Antonio/Austin/Houston/CS areas, I have sample boards, in home sell kits, warranty info and I can get you in touch with my CT rep if you want to get into the nitty gritty of CT shingles. I care not which roofer you select so much as you make an informed decision on the product. Seriously, don't hesitate to reach out if you want free info or bouncing questions. I do it for a ton of folks.

Also, make sure he/she certifies the roof as IR I to obtain insurance premium discount, if available.
