CertainTeed residential shingle lines — Landmark (flagship), Northgate/Landmark ClimateFlex (Class 4), Presidential (designer)

CertainTeed's line follows the three tiers with one notable twist at the designer end. The flagship is Landmark — CT's most-installed architectural shingle, a dual-layer fiberglass build with MaxDef color blends for deeper shadow lines; standard Landmark is limited-lifetime material with a SureStart non-prorated period (CertainTeed covers 100% material and labor on defective shingles during that window) and is NOT impact-rated. For hail, CertainTeed's impact line is built on ClimateFlex, an SBS (styrene-butadiene-styrene) polymer modification that adds the flexibility for UL 2218 Class 4: Northgate ClimateFlex is the premium tier (110 mph standard wind warranty, upgradable to 160 mph WindProven) and Landmark ClimateFlex is the value-tier impact SKU sharing the same technology; both are the lines that may qualify a Texas home for an insurance impact discount (confirm with your agent; cross-reference D1-002). The designer tier is Presidential — and Presidential Shake TL is one of the few shingles that is both a triple-laminate wood-shake designer profile and UL 2218 Class 4 impact-rated, with Grand Manor as the slate-aesthetic sibling. The enhanced SureStart PLUS warranty runs through the SELECT ShingleMaster contractor certification (3-Star/4-Star/5-Star tiers, the top extending workmanship coverage; cross-reference D7-008, D9-004). What to ask on a CertainTeed quote: standard Landmark or a ClimateFlex line — only the ClimateFlex family (and Presidential Shake TL) is Class 4 — and the contractor's SELECT ShingleMaster status if SureStart PLUS matters. Cross-reference D1-009 for the general comparison framework.
