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.

Competitive and professional

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.

Very pleased with the crew

We had a leak in the low-slope roof over the third story of our house. Interstate replaced old plywood and agreed to change the job description to eliminate instead of replace the skylight. We are very pleased with the crews, led by Roman and Mark, and and the job they did.

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.

The new roof looks wonderful

This is the second job I’ve had Interstate do for me, and again, the crew was great. They were polite, respectful, and cleaned up after themselves. The new roof looks wonderful. Any other needs I have for roofing, siding, or windows, they’ll be the first I call!!!

Roofing Trends in Cedar Mill

  • Tree cover makes roof maintenance a serious priority. Cedar Mill homes near wooded lots, established neighborhoods, and the areas around Cedar Mill Creek often deal with leaves, needles, moss, and organic debris that can collect on roofs and in valleys.
  • Moss prevention is part of long-term roof protection. Shaded roof slopes can stay damp for long periods after rain, making regular cleaning and maintenance important for preventing lifted shingles, clogged drainage paths, and premature surface wear.
  • Composition shingles remain a practical replacement choice. Many Cedar Mill homeowners choose composition roofing because it performs well in the Portland-area climate while offering enough color and profile options to match a wide range of home styles.
  • Older homes often need careful inspection before replacement. Some Cedar Mill properties have aging decking, older ventilation setups, or past patchwork repairs, so a thorough inspection helps determine whether the roof needs repairs, maintenance, or a full replacement.
  • Low-slope roofing needs attention around drainage points. Commercial and multifamily properties near Cornell Road, Barnes Road, and nearby business corridors benefit from routine inspections of seams, drains, edges, and rooftop penetrations before small issues become active leaks.
