Art-Loc® Interlocking Shingles in Michigan, Indiana, and Ohio
Art-Loc® is not a shingle you will find at a big box store or through another roofing contractor. It is a patented interlocking shingle system developed and refined by Sherriff Goslin Roofing over more than 100 years, and it is available exclusively through our company.
The interlocking design locks each shingle to its neighbors mechanically, creating a unified roof surface that distributes wind stress across the entire system rather than concentrating it at each individual adhesive bond. In a region where summer microbursts, spring hail, and sustained wind events are a regular part of the calendar, that design difference matters.
Every Art-Loc® shingle comes standard with Scotchgard™ Protector, validated through independent third-party laboratory testing to ensure maximum algae resistance. And every Art-Loc® installation by Sherriff Goslin Roofing is backed by our 10-year free service guarantee.

Available Colors
Art-Loc® shingles are available in nine colors, giving Midwest homeowners the flexibility to match any architectural style or exterior palette. From warm earth tones to bold classics, every color option retains its look and resists fading and algae staining for the life of the shingle.

We’re Answering Your Art-Loc® Shingle Questions
Here are the questions Midwest homeowners ask most often about Art-Loc® shingles.
The defining difference is the interlocking design. Standard shingles rely on adhesive strips and nails to hold their position through wind and hail events. Art-Loc® connects mechanically to neighboring shingles, distributing stress across the entire roof surface.
It is also manufactured using SBS modified polymer rather than standard fiberglass mat construction, which gives it superior flexibility, durability, and water resistance. No other shingle on the market is built this way, and it is available exclusively through Sherriff Goslin Roofing.
Yes, and this is one of Art-Loc®‘s practical advantages. The interlocking design makes it suitable for re-roof applications over existing shingles, saving the time and cost of a full tear-off. Your Sherriff Goslin Roofing project manager will assess your existing roof during the free inspection to confirm it is a suitable candidate for an overlay installation before any recommendation is made.
In many cases, yes. Art-Loc® holds a Class 4 impact resistance rating, which is the highest rating available, and many insurance providers offer premium discounts for homes with Class 4 rated shingles installed. Check your specific policy with your insurance provider for eligibility details. Your Sherriff Goslin Roofing project manager can provide the product documentation your insurer may need.
Art-Loc® carries a 30-year algae resistance limited warranty on the Art-Loc® System Advantage Roofing System. When our team installs a complete Art-Loc® System Advantage Roofing System, that upgrades to an unprecedented 15-year Premium Protection Limited Warranty. On top of manufacturer coverage, every Art-Loc® installation by us is backed by our exclusive 10-year free service guarantee against leaks.
