Cambridge is a premium architectural (laminate) shingle with a dimensional appearance, dual-layer construction, and enhanced wind resistance up to 130 mph. Marathon is a traditional three-tab shingle with a flat profile at a lower price point. Both include algae-resistant granules and manufacturer warranties.

How long do IKO shingles last?

IKO Cambridge shingles carry a limited lifetime warranty and typically last 25-40 years with proper installation and ventilation. Marathon shingles carry a 25-year limited warranty. Actual lifespan depends on ventilation, installation quality, and weather exposure.

IKO's ArmourZone nailing area and competitive pricing make it a strong value choice. We can walk you through the differences during your consultation.

Does IKO offer impact-resistant shingles?

Systems We Install

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.

What Our Customers Say

Tonya T.

“I recently moved into my Franklin home and have contracted several companies for home improvements. Due to the tornadoes in the area in late March, I had roof damage and needed quick assessment to avoid more interior damage. I called Grady Phillips at SPG as they did the roof replacement on my previous home. By that afternoon, my roof was tarped to prevent more damage. Grady and the team worked with my insurance company to get me coverage for a complete roof replacement. They completed the project within a few weeks. Jordan, the on-site manager, answered all my questions and kept me fully informed. The construction team was respectful and quick. I am very happy with the whole process and my new roof. They have been the best home repair company that I have worked with this year.”

Tonya M.

“We had hail damage to our home and detached garage and SPG were prompt with providing an estimate, very friendly and helpful with our questions, and provided exceptional service. They worked with our insurance company (not an easy task) and were in constant communication with us. Their roofing and siding crews worked very hard and cleaned up after the job was complete. I would strongly recommend you contact SPG for your next job. Dustin and AJ will take great care of you and your home through the entire process!”

Forest B.

“SPG is my go-to roofing company. As a commercial real estate broker with many options for roofing companies, Dustin is always my first call when I need a roof checked on. I have had him hop on many roofs between my personal rentals and countless clients. They are always professional, competitively priced, and very responsive. I highly recommend SPG for any residential or commercial roofing needs.”
