I’m very happy with PNW roofing and crawl space company.. They did my new roof and gutters.. My house looks beautiful!! They did an excellent job in a timely matter. They’re team was very professional!! I highly recommend them!! Thank you Alfredo and thanks to your team!!
PNW Roof & Crawlspace Insulation removed our very old cedar shake roof & installed new high quality metal roof; took off and re-installed our gutters when finished replacing the roof; cleaned out, removed and re-insulated, re-screened, & installed vapor barrier in our crawlspace; cleaned out our attic, & removed & replaced our attic insulation, re-screening all the vents, and removed old fascia and replaced it with new, repainted fascia when the roof installation was completed. They took away all the old materials/garbage, and did a thorough sweep of the premises with a magnet roller after removing all trash materials. When we called for an estimate, PNW answered right away, and their estimator was at our house very quickly.Everyone at PNW couldn't be more friendly, courteous and capable! All the work was done quickly, safely, and on time. Everybody always has a smile on their face, and a hard working, can-do attitude. Their prices are very competitive, and communication was always nothing less than excellent. Their printed estimate and handout given at the time of estimation explains clearly and in detail the work to be done, and the specific type and brands of materials that will be used. All safety procedures, final cleanup procedures, and prices are also listed in detail. We work in the construction trade, and we are impressed. Thanks PN for the wonderful job!!
Alfredo, Ana, and the PNW Roofing crew have been timely, responsive, and super helpful to work with. We had a leak in our roof, Alfredo came out the next day, assessed the issue, provided multiple potential solutions at varying price points and levels of disruptiveness, and was overall very knowledgeable. We were able to have our issue fixed within the week. We have also done roof cleaning and moss treatment on our roof - it looks sparkly and new! We would happily book any roofing needs with this crew again.

The owner, Pedro, was very responsive and patiently answered all of my questions. The quote was fair, and his crew was available to get started the next day. They cleaned out, sanitized, sealed, and insulated my crawl space and attic in 2 days. (1500 sqft, 1 story house, built 1968). My crawl space and attic are difficult to access and navigate, but the crew slipped in and out like pros! I inspected the crew's work after both days and the work was clean and sharp!
The owner was very responsive. His crew showed up on time and performed all services excellently. They left the job site in pristine condition. Highly recommend western insulation for any insulation needs.
Christian and his team did a great job. He was fairly priced, came in with a good size crew to replace all of the insulation for our ducts under the house. I would definitely call them again.
