"I used Lane Roofing to repair my flat roof and to replace and install roof shingles. Shawn came out to inspect my project and to give me an estimate was phenomenal. He knew exactly what I needed done for my repair. Thank you Shawn for your professionalism and expertise. Nicely done! 😊"

"Florida room roof had to be replaced, a small job. The crew that came out to replace it did the entire replacement (turned out to be 2 roofs one on top of the other) in about 3 hours. They cleaned up everything including doing a magnetic sweep of the areas wheee they had been working. Iâ m very pleased with the result."
