About Bill's Roofing, LLC
Bill's Roofing takes its name from owner Guillermo "Bill" Castillo. Castillo says he began as a roofer, then worked as a subcontractor and contractor before opening his own company. His career began with the work itself, giving the company a practical foundation in how roofing systems are installed and managed.
The company identifies Shaun Costello as project manager for the Salina office. That gives homeowners a named local contact even as Bill's expands into other Kansas markets.
Bill's installs asphalt shingles, exposed-fastener metal panels, and standing-seam metal roofs for homes. Its commercial work includes TPO, PVC, coatings, metal, repairs, and complete replacements on offices, restaurants, schools, stores, and hotels.
The company assists with storm inspections and insurance documentation. Bill's can explain its findings and communicate about the repair scope, but coverage decisions remain with the homeowner's insurance carrier.
