I was called to a home in the suburbs to repair a leak in a home's roof. Upon arrival, I found that the roof was a 5-year-old Lennox package roof system. I inspected the roof and found that the shingles were curling and had some missing granules. I removed the damaged shingles and replaced them with new ones. I also repaired any damaged flashing and sealed any gaps around the chimney and vents. The customer was very pleased with the work and thanked me for my prompt and professional service.
