At Sherriff-Goslin, we pride ourselves on providing our customers with an exceptional roofing experience and customer service from start to finish.

All roofing shingles eventually wear out. How quickly depends on several factors, including: the slope of the roof, the quality of roofing materials, the quality of workmanship, attic/roof ventilation and the climate in which you live. We find that the typical standard fiberglass or organic shingled roof lasts somewhere, on average, between 12 and 15 years.

Unsightly black stains on shingles are often mistaken for fungus, mildew or dirt but are actually caused by a hardy type of algae. This common problem has increased during the past 20 years, indiscriminately settling on rooftops from coast to coast. Once algae are present in an area, airborne spores are carried from rooftop to rooftop, infesting whole neighborhoods. Art-Loc and StormMaster Shake, Slate and Pinnacle shingles deliver superior algae resistance through innovative granule technology from 3M, a world leader in algae resistant roofing products. Roofing granules containing an inner copper-coated layer of ions, which are time-released, provide long-term algae resistance.

Yes, we also sell and install the StormMaster Shake architectural shingle, made by Atlas Roofing Company. Shake shingles combine strength and beauty in a high-wind, impact resistant architectural shingle for protection against the most extreme weather conditions. Shake architectural shingles resist cracking, splitting, warping and shrinking because of a unique blend of SBS (Styrene-Butadiene-Styrene) in the formula that enhances flexibility and durability. Shake architectural shingles carry a limited lifetime warranty and the Sherriff-Goslin 10-year worry-free service guarantee. Like Art Loc shingles, they carry the best wind and impact ratings along with 3M granules for the best algae resistance. In addition to Art-Loc and StormMaster Shake, we sell and install StormMaster Slate shingles. Slate shingles are also SBS modified and have the 3M Scotchgard granules. We also carry and install the Pinnacle architectural shingle, made by Atlas Roofing Company. Pinnacle shingles are not modified with the SBS polymer. Pinnacle shingles carry a limited lifetime warranty and the Sherriff-Goslin Company 5-year worry-free service guarantee.

Our roofing work carries a special Sherriff-Goslin material and labor guarantee. Our roofs are guaranteed against leaks and defective material with full service at no expense to the customer for ten (l0) years on all Art-Loc® roofing jobs. This guarantee is transferable and thus remains on the roofing job for ten full years regardless of ownership.

Our Sherriff-Goslin guarantee is offered in addition to the 30 year standard manufacturer’s warranty, which in many cases is the only service guarantee offered by our competition. The manufacturer’s warranty, however, covers only reimbursement for defective materials and at a reduced rate for each year after initial installation (prorated). These manufacturer’s warranties are limited in that they apply only to the original purchaser and assume no responsibility for leaks in chimney or wall flashing, or valleys, or for workmanship related issues, and they do not cover repair or replacement labor.

Yes, we offer financing for every new roof we install with approved credit.
