Certified by the Best
We carry exclusive certifications from leading manufacturers.
IKO Cambridge — Premium Architectural Shingles
The IKO Cambridge is a premium architectural shingle that delivers exceptional curb appeal with its dual-layer laminate construction. Cambridge shingles produce deep shadow bands that replicate the look of natural wood shake at a fraction of the cost. Available in a wide range of colors including Driftwood, Weatherwood, Dual Grey, and Harvard Slate, Cambridge shingles complement any architectural style from traditional to contemporary.
Cambridge shingles feature IKO's ArmourZone reinforced nailing area, which provides a wider target for proper fastener placement and enhanced holding power during high winds. Combined with the factory-applied sealant strip, Cambridge achieves wind resistance ratings up to 130 mph when installed per IKO specifications. Every Cambridge shingle includes algae-resistant granules to maintain a clean appearance for years.
IKO Marathon — Reliable Three-Tab Performance
The IKO Marathon is a traditional three-tab shingle built for homeowners who want dependable performance and clean aesthetics at an affordable price point. Marathon shingles feature a uniform, flat profile that delivers a classic roofing appearance. While simpler in design than architectural shingles, Marathon offers solid protection with algae-resistant granules and reliable wind resistance.
Marathon is an excellent choice for budget-conscious projects, rental properties, and homes where a clean, traditional look is preferred. SPG installs Marathon shingles with the same attention to detail and manufacturer specification adherence as our premium installations, ensuring proper ventilation, underlayment, and flashing for maximum service life.
IKO Shingle Technology
IKO invests heavily in shingle engineering, and the results show in the field. Their ArmourZone nailing area is a reinforced band across the shingle that makes proper nail placement easier for installers and provides measurably stronger holding power than conventional nailing strips. This matters in Indiana where straight-line winds and severe thunderstorms regularly test roofing systems.
IKO's manufacturing process uses a fiberglass mat base coated with weathering-grade asphalt and ceramic-coated mineral granules. The granules provide UV protection, fire resistance, and the color that defines your roof's appearance. IKO's quality control includes regular third-party testing to UL, ASTM, and CSA standards for wind uplift, tear strength, and fire resistance.
Why Indianapolis Homeowners Choose IKO
IKO offers a strong combination of proven performance, aesthetic variety, and competitive pricing that appeals to central Indiana homeowners. Their Cambridge line directly competes with premium architectural shingles from other manufacturers while often coming in at a lower installed cost. For homeowners who want the dimensional look of architectural shingles without the premium price tag, IKO delivers.
SPG has installed IKO shingles across multiple Indiana communities including Anderson, Greenwood, and surrounding areas. Our experience with both the Cambridge and Marathon lines gives us practical knowledge of their installation characteristics and long-term performance in local weather conditions.
