Our Commercial Roofing Materials Steep-slope, low-slope, and commercial flat roofing in Portland & Vancouver

The best roof material for your commercial property depends on the slope of your roof. You can rest assured that our roofing expert will recommend the right material for significant long-term benefits on your building.

Composition Roofing

For steep slope roofs (churches, apartment buildings), we recommend composition roofing. Composition shingles are a versatile and durable option, making them a perfect solution for steep-slope roofs - made from a mix of asphalt, fiberglass, and mineral granules.

Asphalt roofing shingles for commercial roofs

TPO Roofing

For low-slope roofs (warehouses, office buildings, and medical offices), we recommend single-ply TPO roofing. TPO is made from a blend of plastic and rubber. It’s an extremely durable and cost-effective solution for large-scale flat roofs.

From quality products to quality people, it is easy to see why so many neighbors already chose Interstate Roofing. While comparison shopping, I found some competitors could take days to a week to respond, but Interstate was always prompt. Communication throughout the install was great. They had installers available, so our 2-story was completed in one day. The unpredictable weather had us worried as we’ve seen some companies take over a week.

We had an excellent experience with Interstate roofing. Oscar and Franco did the 2 day job. Oscar was informative and professional, taking pictures of the before and after. They blew off leaves and washed some of the siding for us. Oscar let me know every step and how long it would be and they cleaned up nicely when they were done. They sent out their inspector after the job was completed to make sure everything was done correctly. Very thorough.

The crew at Interstate were friendly and hard working. I felt like the sales person was honest and experienced and I was confident in my decision to hire them. The daily crew worked hard and cleaned up after each day. They came back at the end to clean up debris at my neighbor's house as well. I appreciated the communication and think the roof looks amazing. I would have appreciated a more comprehensive materials list because there was some confusion at the end of the job about whether or not the left over materials belonged to me or not, but I didn't have that information so I can't be certain. All in all I think they did a great job and would be happy to recommend them to others.

I am beyond thrilled with the job Interstate Roofing did for us. We have used other roofing companies in the past, however Interstate surpassed all of them from our interactions from start to finish. Their estimate was well detailed, the workers were here on time each day and communicated with me about their progress, they kept me informed on what needed repair versus just clean. The best part is I left on day one, looking outside and seeing all the debris all over our yard and I was concerned, however upon returning home they did such an amazing cleanup job it was like they weren’t ever here. On the second day not only did they clean up they also power rinsed the entire house, it all looked amazing. If you want the job done right use Interstate Roofing!!!

Of the 8 quotes we got for a new roof, Interstates was both the most competitive and professional. Ronnie and co did a great job from bidding to start date, and the crew worked long days to get the job done fast. All in a great experience.

Interstate replaced the entire roof on our office building back in 2018, helped us track down a tricky leak, and have continued to provide ongoing maintenance for our roof. Through all these different tasks they are consistent - always knowledgeable and communicative, very easy to work with, and their crews take a lot of (well deserved!) pride in their work.

We hired Interstate to re-roof one of our commercial buildings. They were able to get the job done in two days with a minimum of disruption for our tenants. They were professional and courteous, they cleaned up every day and our tenants were very pleased with the work they did. We would definitely hire Interstate again.

The crew was amazing! It was choreographed perfectly with the drop box, material drop off and final clean and pick up. There was no trace of debris left behind. The crew was fast! They completed the house and two outbuildings in two days! Communication and Cost were impressive. Highly recommended!

I reside in a large development in Salmon Creek. Currently, all of the roof's, including car ports, are being replaced. I applaud the professionalism, kindness and attention to detail the construction team embodies. Their work ethic is impeccable and they are very clean. Throughout this brutal heat wave, they are tirelessly working and maintaining the cleanliness of the development. There are postings indicating parking spots to be closed off and cones are placed all around to ensure the safety of both the residents and construction team. When the work day is coming to a close, they clean up the surrounding areas, all be it some of the residents have planters, flowers, etc and they are respectful of that and remove all garbage. With any construction site, I don't care where it is, there will always be some debris that might unintentionally get missed. I have seen the hard work and communication this team has and the respect they show one another. I have not had any issues with my building or any trash left behind that was not picked up. Of course, if I came across a nail I would simply pick it up and discard of it. Just want to thank you for helping this development by replacing the roof's, they look fabulous.

Interstate Roofing is in the planning process for re-roofing our 3 story, 41 unit condo building, set to begin sometime this Spring. They have all been so very helpful since the day the Inspection was done in September. Terry Nation, their "Low Slope Estimator" has been wonderful with answering questions and expert advice. He even came over for a Board Meeting and fielded so many Owner questions, that made everyone there, feel comfortable with what they will be paying for! Not an easy task! Thanks Terry, you are a great asset to the company!!!! Stephanie Paul, MTC HOA Board President

Recently, we had interstate roofing company re-roof three buildings in our complex. Their professionalism, communication, skills, attention to detail, and workmanship are above average. This was a complex roofing job, and they completed it without a hitch. Their supervisor and safety manager were on site at all times, providing information, which made it easy to discuss the job and get answers promptly. I highly recommend their services.
