Khalil did a masterful job on my roof. I know this because friends who are knowledgeable (a home inspector and and an experienced housing professional) told me. My roof wasn't easy. My home is an antique--more than 100 years old with many complicating angles. Khalil is a perfectionist and treated my home as though he were working on his own. When he left, he cleaned everything--there wasn't a nail on the driveway and it all looked great.
