Permanent lighting runs $28 to $38 per linear foot installed. Most homes need between 100 and 250 feet of roofline, so a typical project lands somewhere in the $3,000 to $8,000 range. Where you fall in that per-foot range depends on roof height, number of stories, and how complex the rooflines and gables are — a single-story ranch prices at the low end. We measure your actual roofline during the free consultation and give you a fixed written price before any work starts. The number we give you is the number you pay.
