COMMERCIAL ROOFING Q&A

Frequently Asked Commercial Roofing Questions (And Answers!)

If you have questions about your business’s roof, Sawtooth Roofing has answers!

1. What types of commercial roofing systems does Sawtooth Roofing install?

We specialize in flat and low-slope commercial roofing systems including TPO, PVC, EPDM, and metal roofing. Each is tailored for durability, energy efficiency, and performance in the Pacific Northwest climate. Explore our Commercial Roofing page for system details.

2. How long does a commercial roof typically last in Portland or Southwest Washington?

The lifespan of a commercial roof varies by material:

TPO/PVC: 20–30 years
EPDM: 25–30 years
Metal: 40+ years

Wet weather and moss growth in our region can shorten lifespan if not maintained. Schedule a free inspection to assess your current system.

3. How do I know if my commercial building needs a roof replacement or just repairs?

Common indicators include persistent leaks, ponding water, blistering, or membrane tears. We conduct thorough evaluations to determine if targeted repairs are sufficient or if a full replacement is more cost-effective. Contact us for a free estimate.

4. What is the best roofing material for flat commercial roofs in the Pacific Northwest?

TPO and PVC are ideal for flat commercial roofs in Portland and Southwest Washington due to their durability, UV resistance, and waterproofing ability. These systems also support solar installations and meet energy-efficiency standards. Learn more on our Commercial Roofing page.

5. How often should I have my commercial roof inspected?

We recommend a biannual roof inspection—once in the spring and once in the fall—to catch issues before they disrupt business operations. High-traffic or aging roofs may require more frequent checks. Schedule a free inspection to stay ahead of potential issues.

6. What causes commercial roof leaks in the Portland area?

Frequent rain, clogged drains, membrane punctures, aging materials, and poor installation are leading causes of commercial roof leaks in the Pacific Northwest. Proactive inspections and maintenance can prevent costly water damage. Explore leak solutions on our Commercial Roofing page.

7. Can roofing work be completed without disrupting business operations?

Yes, Sawtooth Roofing works with property managers and business owners to schedule roofing work during off-hours or low-traffic periods. Safety, access, and noise control are all factored into our project planning.

8. Do you provide roof maintenance programs for commercial properties?

Yes. Our preventative maintenance programs help extend the life of your commercial roof and reduce emergency repair costs. Services include debris removal, drain checks, seam sealing, and membrane inspections. Learn more at our Commercial Roofing page.

9. What are the signs of commercial roof failure?

Watch for these red flags:

Increased energy bills
Persistent leaks
Mold or mildew odors
Pooling water or soft spots

If your roof shows these signs, schedule a free inspection to determine next steps.

10. Does Sawtooth Roofing handle multi-building commercial projects?

Yes. We have the capacity and experience to manage large-scale and multi-building commercial roofing projects for retail centers, industrial parks, warehouses, and more. See our full capabilities on the Commercial Roofing page.

11. Are your commercial roofing services backed by warranties?

Absolutely. We offer both manufacturer warranties (typically 20–30 years) and Sawtooth workmanship warranties, giving your business peace of mind and long-term protection. Warranty details vary by roofing system.

12. Why should my business choose Sawtooth Roofing for commercial roofing services?

We have already recommended Sawtooth Roofing to several people. From the very beginning Darrin made sure we had ample information and was very responsive in patiently answered our questions. After multiple roofing quotes, he was the first roofer that showed and explained the mathematical formula utilized to determine how many vents one’s house needs. This and other shared information showed me that Darrin truly was very proficient in his field and Sawtooth was a company we could trust our home with. Because of some health issues, this was very important for us in making sure our attic air flow was healthy and without issues due to improper amount of vents. Sawtooth not only uses quality material but installs with quality work. As one who’s highly health sensitive to any building issues, Darrin and the team really worked above and beyond with particular details we needed. I was so grateful for their patient listening, communicating clearly via email/phone/in person, and asking questions to make sure they understood what we were looking for, along with taking any extra time needed to ensure quality work. Because of this, for the first time in a long time, I’ve increasingly experienced better health than I’ve had for quite awhile. As I’ve said several times before, having a roof properly installed was the best ‘doctor’s’ visit I could’ve had!!! The roofing team was also exceptional in the same way, as was the office staff. And, by the way, to top it off, the roof also looks fantastic! Thank you Sawtooth!

A great service and great product for a fair price. Actually the best price we were quoted for a premium product. The roofers were courteous, efficient, on-time and very clean. Our 2 story house and detached garage were completed in 3 days. They cleaned up at the end of each day. Highly recommend.

Replaced existing roof that had been poorly installed. Very pleased with the result. Tom was responsive and explained their proposal and materials clearly. Cost was reasonable. Job was completed in a timely manner with attention to safety. Removed an unused interior chimney to the roof level. Only minimal (unavoidable) damage to plants. Cleaned up debris from old roof.

Recently replaced our roof by Sawtooth, Sawtooth did an excellent job. Also the quote from Sawtooth was at good price with high quality Owens Crowning Trudefinition shingles with PLATINUM warranty. Among 6 quotes Sawtooth has given the excellent quote for my complex roof. Workers were highly skilled and did an excellent job.. Another excellent thing I like Sawtooth, they added extra vent on the roof to balance in and out air flow which helps the house keeping more cooler at hot weather and less usage of Air conditioner.

We had our roof done in May and had a great experience working with Tom and his crew. Tom was very communicative and the team efficient and kind. I have recommended Sawtooth Roofing a few times since and will continue to do so. Our neighbours have also told us they have have been admiring our roof. 🙂

I just had Sawtooth install a new roof. I was very impressed with the crew. Amazing hard workers who worked until dark and started early each day early to get my roof complete in less than 3 days. Meticulously cleaned everything up. Very impressive quality work and my roof looks awesome! I would definitely recommend Sawtooth Roofing Company. Ruth Risch

I picked Sawtooth out of 6 bids. I needed a full tear off of asphalt shingles plus a layer of cedar shake, repair to a soffit, and two skylights. The crew worked very hard to get it done in 4 days and I'm very happy.

Sawtooth were very professional in bidding a full tear-off and new roof installation, submitting the agreement, timeline and method of payment for carrying out the work. We agreed the price and time frame, weather permitting, (winter time install), and the work was carried out in less than four days leaving the site clean and free of debris. We are very happy with the service and would recommend Sawtooth to other residential owners we know. Charles

We had our 24 year old roof replaced back in 2021. While we were listing the house in 2024, it became very apparent that that contractor did not install our roof system properly back in 2021. Darrin Webster at Sawtooth was invaluable at helping us evaluate the problem, guiding us through the process of submitting a claim then pursuing the best solution for our buyers. Using Sawtooth Roofing for this repair was a great decision and I highly recommend this company! Thank you, Darrin, Joe, Alicia, Elias and the whole Sawtooth Roofing crew!

Sawtooth reroofed our entire house and separate shed, including rebuilding a section covering our patio. The quality of work, attention to detail and meticulous cleaning of the yard and driveways was second to none. Elias and his crew worked tirelessly and completed the job in less time than expected. I recommend them without any reservations. Job well done!

Every step of the process went so well! The team had deep knowledge and skills, was responsive to my questions, expertly worked long hours on the hottest days of this year, and quality-checked multiple times to ensure that the end product is a high-quality roof for my family. Thank you and gratitude to the whole team!

Sawtooth Roofing has great friendly service. From the first interaction when Tom came out to look over the roof and give an estimate through the installation and afterwards, the inspection, the staff is very helpful and they made sure we understood the process. The roof looks terrific. The crew did a wonderful job cleaning up after the job was complete. We would highly recommend Sawtooth Roofing.

Unfortunately we had to completely replace our roof but fortunately this crew made it a little easier. They were kind, efficient, cost effective and fast. All things you'd want in a roofing company. The warranty is mainly why we went with this company after at least 5 estimates. The only issue we had was parking but our house is at the end of a court so it normally has issues. I just wish they had parked outside of it like we asked. Especially on garbage day ?

Sawtooth Roofing just put a new roof on my 1929 Portland bungalow. They were fast, efficient, professional and the quality was first rate. They were also the low bid out of three bids. I would not hesitate to use Sawtooth Roofing for any roof replacement or repair needs.

Darrin was over at a neighbor's house re-doing their roof. I asked him to come by and look at ours. He was happy to do it and I appreciated his honest opinion, but I especially appreciated that when he saw the state of the rubber gaskets on our vent pipes he said he'd replace them - for free! I offered twice to pay him and he said 'no big deal' it's just a good thing to do. He walked up on our roof and was done in five minutes! Wow, would totally ask Darrin for a bid when it comes time.

We just had this amazing company reroof our house and it turned out perfect. The quality of products they use vs the competition is by far way better. They got the job done in 2 days which is amazing. These guys work so hard to make sure their customers are happy. Thank you so much to their awesome team.

We had a wood shake roof and contracted Sawtooth Roofing to tear off the old roof, install new plywood on the entire roof. They then installed the new premier roof. They did it all in a very professional manner. The work crew started every day in a timely manner, worked hard and kept the work area as clean as they could. We are very pleased with the final product, I did have sticker shock when I got the bid but I feel they did everything to earn it. We are very pleased with the final product knowing that what is under the roof was done properly and knowing we now have a great new roof for the protection of our home. Thanks Sawtooth and the great crew that installed our new roof, it looks great and we couldn’t be happier. Thank you, Shellie and Dexter Hill

They did the fastest roofing job I ever saw. They started one morning and they were cleaned up an out by noon the very next day. The quality of the work was excellent. I looked at a neighbor's roof, done the same month by a different contracter and they had uneven surfaces. Mine was perfect. I have used Sawtooth before and I will continue using them.

I have been in real estate business for over 17 years and been involved in dealing with many contractors. I have seen too many roofs poorly installed by unqualified roofing companies. We hired Sawtooth Roofing for a new roof on our personal home. We couldn’t be more pleased. They delivered on all promises and more. They were on time, clean and the price didn't change. OUR NEW ROOF IS GORGEOUS!! This company really delivers and does business how you expect a highly professional contractor to be. We highly recommend Sawtooth Roofing!! Give them an opportunity to earn your business, you won't be disappointed!

Customer service was a 4+. Very friendly and kept all their promises. Workmanship was a 2. Poor attention to detail. Broken siding and reused flashing that was poorly done. Nails and bits of garbage EVERYWHERE (we have pets, too!) We called to complain and they did sent someone out. However, they never communicated with us that was happening. We called to follow up and they met us, walked through our concerns and EVERYTHING was fixed to our satisfaction. It just took a while. If more quality work would have been done from the beginning, the score would have been much higher.
