IKO is the largest privately-held asphalt manufacturer in North America and has gained Portland market share consistently in recent years. The Cambridge line is the volume product; Dynasty is the standout impact-rated shingle (Class 4 UL 2218) that's well-suited to fallen-limb damage on canopied Portland lots. The ShieldPRO Plus credential is comparable to GAF Master Elite and CertainTeed SELECT ShingleMaster in selectivity.
IKO's product hierarchy centers on Cambridge — a value-priced architectural shingle that competes with Timberline HDZ and Landmark on price (often slightly below) while offering similar performance specs (110-130 mph wind, 30-50 year warranties depending on credential). Dynasty is IKO's flagship impact-resistant line with the Class 4 hail rating using ArmourZone reinforced nailing. Royal Estate and Crowne Slate are the designer lines for heritage homes.
From mass-market architectural to designer luxury
Value-priced architectural shingle. 110 mph wind rating standard, 130 mph upgrade available. Algae Resistant coating standard (10-year limited warranty). $3.50-$5 per sq ft installed in Portland — often 10-15% below GAF/OC on equivalent specs.
Class 4 UL 2218 impact rating with ArmourZone reinforced nailing strip. SBS-modified asphalt for flexibility in cold weather. 130 mph wind. $5-$6.80 per sq ft installed. Strong choice for canopied Portland lots.
Designer shingle with deep shadow line and dual-layer construction. $7-$9.50 per sq ft installed.
Synthetic slate appearance. Common on heritage homes. $8-$11 per sq ft installed.
What the credential tiers mean and how rare they are
Top-tier IKO credential. Requires the contractor to hold proper licensing, carry $1M+ liability insurance, maintain customer satisfaction scores, and complete advanced product training. ShieldPRO Plus contractors can register the Iron Clad Protection warranty (50-year non-prorated on full system). Roughly equivalent to GAF Master Elite in selectivity.
Mid-tier IKO credential. Requires factory training and current licensing. ShieldPRO contractors can register the Premium Protection warranty (lifetime limited with prorated coverage starting at year 15). About 6-8% of US roofers.
The base material warranty on Cambridge shingles is Limited Lifetime (prorated after year 15). The Iron Clad Protection extended warranty (available with ShieldPRO Plus installers) extends to 50-year non-prorated on the full system, including IKO underlayment, ice shield, ridge cap, and ventilation. Registration is required within 60 days of install. Warranty is transferable once during the first 15 years.
IKO has solid Portland distribution through ABC Supply and Lyons. Cambridge is typically stocked in standard colors with 1-3 day lead time; Dynasty and the designer lines run 5-10 days. The ShieldPRO Plus contractor pool in Portland is smaller than the GAF Master Elite or CertainTeed SELECT pools, so matching availability varies.
