Alex's team is CertainTeed-certified and backs shingle work with a 30-year warranty, sending photo updates throughout each job. The five-star average is strong, though it's built on a smaller pool of 17 reviews, so it's worth weighing alongside the larger-volume names on this list.

• 30-year warranty on shingle work
• Documented photo updates throughout the job
• Fast emergency response

Watch out: Five-star average is based on a relatively small review count so far.

This company advertises over 30 years in business and 24/7 emergency coverage for flat, metal, and waterproofing work.
