Just got a new roof with flashing repairs and new intake vents for our house in Portland, couldn't be more pleased with the job they did. Communication was 100% transparent, there were additional charges to replace a couple of sheets of plywood, but they discussed the possibility before we signed a contract. Materials used were good (used ACX plywood and Corning TruDefinition shingles), we would definitely use them again.

This is the second time Ive hired Interstate. Two years ago they re-roofed my house and that experience was so good, there was no question about what company I would call to have our shop building re-roofed. They are excellent! While price is always a consideration, honesty and quality of work are most important to me. I was so confident hiring them that I didnt even bother with other bids, and once again, they totally met my expectations. They show up on time, do great work, cleaned up the area so well its hard to tell theyve been here, and are perfectly easy to work with. Ive recommended them to family members and have no hesitation recommending them to anyone in need of a new roof. Interstate Roofing is wonderful!

Interstate replaced our steep, complicated roof including 2 cupolas and a gazebo. It was difficult and involved working with the carpenter who was replacing the rotten cupolas. The foreman, Antonio, was awesome and always helpful and available. The estimator, Sean, was very friendly and knowledgeable. The crew, Julio (the foreman) were very hardworking and efficient. Tresa, in the office, felt like an old friend. Highly recommend

After a couple other bids, Interstate gave me the most fair, and seemingly honest estimate! The other companies claimed my few loose shingles meant a new roof was an immediate necessity. Interstate optioned me to just replace the shingles, until I could save up additional funds for my new roof! A year later, I just had the roof job done. Workers were prompt to scheduled time, efficient and FAST. My beautiful new roof was completed ahead of schedule, and yard debris cleaned up like new (they even ran a MAGNET over my grass, in case of any loose nails!). I highly recommend them for fair and honest work. ...and that's hard to find these days.
