TAMKO Heritage vs IKO Cambridge 2026
When to choose TAMKO Heritage.
- American-made manufacturing matters to you or to your buyer.
- Your supplier stocks TAMKO Heritage at a meaningfully better price than the regional IKO distributor.
- You want the Algae Cleaning Track granule blend specifically (TAMKO's algae approach uses copper-infused granules that activate during rain).
- Color choice matters and TAMKO's 30 colors include shades like Virginia Slate and Shadow Grey that IKO doesn't match exactly.
- You like TAMKO's heavier-than-average laminate feel for a budget shingle.
When to choose IKO Cambridge.
- Your supplier stocks IKO Cambridge and you want the most-installed budget architectural in North America.
- The 130 mph wind warranty upgrade is required for your insurance class or your county wind zone.
- You want a 10-year algae warranty written into the standard product rather than as an optional granule upgrade.
- Color choice favors IKO's Dual Black, Dual Brown, and Weatherwood — distinctive two-tone granule blends.
- Your contractor is already an IKO ShieldPro Plus and you get the extended workmanship coverage as a result.
