SQI is the best commercial roofing company in this market. The new ownership team and leadership team are excellent to work with. They are knowledgeable and professional. Their quality of work is second to none. I always get a competitive quote in a timely manner. They are the experts in roofing so I don't have to worry about this scope of the project. I highly recommend SQI. They earned my business.

Put a new roof on our existing shop. Did excellent work, always cleaned up at the end of shift, kept a professional, responsible worksite. Completely changed the appearance of our building and significantly reduced the airplane noise from Paine Field jets flying over. Would highly recommend them. Scott - Combined Construction

This company has had it's ups...and downs. They did the roofing on our apartment building and we have had very little issues. In the past, it was a little hard to get them to respond... However, recently I had a leaky roof, they came within two hours to "fix it". Whatever they did didn't work so I called again today. The receptionist said she would call the roofer and get him back out. I received a NO SHOW...along with NO CALL. The tenant said the first time he wanted attic access but couldn't open the attic without a key. Ummmm, you turn the lock with a screwdriver. He couldn't figure that out? He didn't want to do the work. Now, we have a leaky roof. Maintenance, (not the roofing company) said the vent collar the roofer "fixed" was not secured, and now there's mold in the attic. SQI doesn't really care if they work or not. Too bad....I really wanted to like them.

To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
