If your roofer left shingle granules clogging the gutters, used mismatched materials, or didn't stagger the seams, those are red flags. Another sign is when they skip installing proper flashing around vents and chimneys, leading to leaks. A bad roofer might also leave exposed nail heads or nail pops, and their work could look wavy or uneven from the street. They often rush the job, skip cleanup, and won't provide a detailed written warranty.
