Hired Northern Flow to clean my roof and gutters. Due to my mid roof having eaves from the above roof the baking soda isn't washing down. I spoke with the owner and they are coming back to make it right.

My roof is getting old and was covered in debris and moss. They got it nice and clean before wildfire season so it feels safer and should last a little longer. They also went above and beyond and removed two inoperable satellite dishes AND salvaged my shed roof that was buried in moss AND cleaned my gutters.
VERY HIGHLY RECOMMENDED!
Satisfied customer for life!

Excellent work and service. I would highly recommend again. They came to clean my roof and gave the love and attention to my house that it desperately needed. They also provided clean up of the debri afterwards without leaving a mess for us to worry about later, which not all companies take the time to do.

Cord and his co worker did a good job on our tile roof removing debris without power washing it. The attention to detail, like covering flower pots etc and the clean up was great too. I would recommend Northern Flow for your roof maintenance.

As a first time home owner and the first time I had to get my roof and gutters cleaned up, I had no idea what to expect. I searched for roof cleaning services and got a couple quotes. My wife happened to have a coworker that had a positive experience with Cord and got his number to set up a free estimate. Cord came out and was far more friendly and personable than others. He also came in at a far more reasonable price with a great guarantee. Cord and his team were very prompt and even accommodating when it came to my schedule when my wife was sleeping during the early day (she works graveyard). By far happy with Cord and Northern Flow LLC. 10 out of 10 recommend

I highly recommend Northern Flow. The owner was fast in responding to my initial request for an estimate and scheduling my roof cleaning. I’ll be hiring Cord for more projects in the future. I have an unusually tall house and they were able to accommodate roof cleaning with extra tall ladders! I’m very happy with the experience and my metal roof looks new again. Five stars!

Larissa Perara

Highly recommended! It is a dependable company with reasonable rates providing lasting, impactful results.

After getting my metal roof cleaned & sanitized, I could really tell the difference (I'm allergic to mold) providing cleaner, fresher air in and around my home.

I will be using them in the future for power washing and other services the provide this Spring!

Chord answered immediately and made it so he could provide an estimate within a couple of days and the was out a day later with his crew.

They were polite, friendly and very professional. Easy pay and review options and very reasonable price for top notch quality.

He even went above and beyond what I asked for.

Highly recommend and with a 2-year guarantee on his work/product; it’s a true value.

Excellent!!

Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

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.

5. How to choose a roofing company?
+-

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.

6. How do you know if your roofing contractor is ripping you off?
+-

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.
