Short version: both are architectural IKO shingles that carry the Limited Lifetime IKO Shingle Warranty, and on a typical 30-square Wilmington-area roof the price difference is about $150 total — $352 per square for Cambridge versus $357 for Dynasty. Dynasty’s extra $5 buys a reinforced nailing zone that improves fastening security, which matters most on coastal roofs that see real wind. If your home is exposed — near the water, open lot, second-story roofline — Dynasty is usually the better spend. If your roof is sheltered and you like a Cambridge color, Cambridge is a fine roof.
What do the two shingles have in common?
Both are laminated architectural shingles — the thicker, dimensional profile that replaced old 3-tab as the standard. Both install over the same underlayment system, both carry the Limited Lifetime IKO Shingle Warranty, and both qualify for Extended Iron Clad Protection available through our IKO ROOFPRO Select certification. Tear-off, disposal, and cleanup price identically. On our instant quote, switching between them is one tap — the itemized number updates in front of you.
Where does Dynasty earn its $5?
Dynasty is built with a reinforced band through the nailing area. Fasteners driven through that zone grip more material, which is the mechanism behind better wind resistance — and wind is the coastal question. A nail that holds is the difference between a roof that sheds a squall and a roof missing a course of shingles afterward. Dynasty also carries some of the line’s most popular color blends, including Driftshake.
Where does Cambridge make sense?
Cambridge is the value pick without being the cheap pick — same warranty class, proven profile, and a color range that includes Frostone Grey, Olde Style Weatherwood, and Castle Grey. On sheltered lots, inland sections of the service area, or rental properties where the budget math leads, Cambridge does the job honestly.
So which should you choose?
It’s rarely the $150. It’s exposure and color. Pull up both palettes, look at your street, and if you’re within sight of open water or your roofline catches the wind, lean Dynasty. Either way, the price is itemized before anyone calls you — enter your address, pick a shingle, and see the whole number in about 60 seconds, locked for 30 days.
