What’s the cost premium for Class 4 shingles over standard architectural?

Class 4 shingles run $25 to $45 more per square installed, which is roughly an extra $750 to $1,400 on a typical 30-square Madison County home. Brands vary: GAF Armor Shield II and CertainTeed NorthGate sit at the lower end; Malarkey Vista and IKO Nordic at the higher end.

The math usually favors Class 4 in Illinois once you factor the insurance discount. A $1,000 premium offset by a $200 annual discount pays for itself in five years and earns money every year after. Add the reduced claim deductibles many carriers waive on Class 4 roofs and the case gets stronger. Trill quotes both options and lets the numbers decide.
