Best Polyurethane Foam Roofs in Phoenix AZ

Updated review - 2 weeks later - Downgraded from 5 stars.

Our experience with this company was mostly good, but in the end a substandard topcoat sealant really hurt Renco's review with us, because it is the component that determines whether the roof will last a long time or oxidize within a few short years and need early replacement.

Some good points: Renco's bid was neither the lowest nor the highest of the 5 companies and 4 different types of roofing materials we considered. However, they were the ONLY contractor willing to take the old roof off before putting the new roof on. In fact, the salesman said that's the only way Renco is willing to do flat roofs, by tearing off the old roof first. And because we had a 20-year-old torch-down roof that was leaking in several spots, this was the only thing that made sense to me. Why would all these other companies want to install a roof that costs $10-15k or more right on top of an old, leaky roof that has blisters and buckles from 20 years of Arizona heat?

Workmanship was good, but not excellent. The Ripout crew was excellent. The Foam crew was amazing. The Topcoat, as previously stated, was terrible. At first I thought it might have been the topcoat crew that was to blame, but then I realized Renco's standard application process simply does not use enough topcoat material. I've asked the salesman, the foam crew and the topcoat crew how much sprayed-on elastomeric it takes to achieve the industry standard (~15 mils thickness) on a rough surface like polyurethane foam. Nobody knew the answer.

I can tell you from experience that Renco has a standard topcoat application rate that does not account for very rough areas, extra porous areas, and other hard-to-fill areas. And besides, various tradesmen I've spoken with say elastomeric should be rolled on for best results, not sprayed. So... while I was re-painting the parapet wall caps after roof installation, I also had to buy an extra 5 gallons of high quality elastomeric and re-seal several areas where the elastomeric topcoat was so inadequate that foam roofing material was still showing through after Renco had supposedly put down 3 coats (yeah, the topcoat crew came back out a second time, and it still wasn't right after 3 coats).

Renco may warranty the roof for 5 years, but I've been told by many reliable tradespeople that if you take care of these polyurethane roofs correctly, they should last practically forever. We didn't pay $12,700 to have the roof last only 5 or 10 years due to a substandard topcoat which would cause early oxidation and subsequent failure. So... I have and will continue to do everything in my power to make sure this roof lasts a good long time. And I'm sure it will last a long time, as long as I am the one doing the re-coating that is required every 3-5 years.

I'm glad we went with Renco for a number of reasons, but buyer beware. Inspect their work and don't accept the job until it is done absolutely right. If your topcoat looks uneven, get some good elastomeric and re-coat it yourself with a high-nap roller. Protect your investment.

Great service! We just used Ky-Ko to do some repairs to our roof after a pretty bad storm. They were responsive on getting us a quote. Quote was reasonable (we received other quotes too), the crew turned up when they said they would and were quite efficient on getting the job done. Cleaned up the area when they were done. Thomas was a great crew chief as were everyone else I talked with.

I called in today for full roof replacement estimate. Lyons have poor customer service. One lady answered the phone and with out warning another one jumped in. I though was getting help, but the second lady said, the other lady had to leave. I had to provide the same information again to the second lady, which is not convenient to me. The people might do good job or bad, I do not know, but their customer service needs to go through a business environment training.
I do not need to be treated poorly, because I am customer and bringing to them job.

My job

They did a really good job of repairing my back patio roof. I would recommend them.

Owners are honest and easy to communicate with. Employees worked all day every day and were always on time and courteous. The job site was cleaned up at the end of each day and I was then informed of the work to be completed the following day. I received everything that was contracted for and then some. Excellent roofing company, best in the valley!

After 3 wrong companies. I called Michael and he resolved my roofing problem easily. They were very punctual and efficient. Michael was also very easy to work with.

This company does a great job for a fair price. I would definitely recommend them. They also get the job done quickly!

I got hired on and great place to be here super positive, and the bosses are great and professional and so are the roofers, you wont regret it at all to hire this company to do your roof

Diversified roofing did a roof inspection and repair for us after we had some damage done to our roof. They were very responsive and communicative. They came out quickly to fix the problem. Everyone we worked with were kind and helpful. I would recommend them to anyone.

Naomi and shauana great people great experince

1. They said the job would take one day. So far it’s been two and the job isn’t done. They canceled the first day because they said their equipment was faulty. They rescheduled and had to cancel again because of rain... and now the job isn’t even done and they’ve been here multiple days.
2. This is our second night without air conditioning in Phoenix. They unhooked the A/C unit to spray under it and when they moved it back it didn’t work. Instead of remedying the situation, it’s now going on two days (and nights) without air.
3. They left trash all over the yard and sent some random person to come pick up his trailer that he was letting “Joel” borrow... it wasn’t even the company’s trailer. ??? There’s still a huge piece of plywood in our driveway.
4. I just bought brand new patio furniture and apparently they didn't think to tell me the polyurethane spray would get everywhere- so now it’s covered in little white dots.

This has been a really awful experience. I hope the roof doesn’t leak. LOL We shall see come monsoons.

We unfortunately had no choice in which roofing company re-did the roof as our landlord chose.

Update: the roof is now completed. Kyle, the spray foam guy, was the only professional guy I talked to. He was helpful and answered my questions.

Excellent work on time friendly and finished in one day and it looks awesome. Don't be afraid to hire this company.

We are very glad to have picked Next Gen services to get the roof redone. Being first timers, we had no idea or understanding of the optimal roofing solutions. Turner and his team were very professional and prompt in addressing the issues. Would definitely recommend. Anyone looking for trusting roof experts, these are the guys.

Professional, timely, great communication. Have used them for 20 years.

They did a great job. And, they informed us of additional work that may be needed later in the future. Thanks for the heads up. They were all very polite.

Has them out a couple times and they've done fantastic work both times. Friendly, professional, able to talk through the issues and give accurate estimates. Really appreciate all the work they've done on my house!

As expected, Overson Roofing was a good company for the job - a new roof. Working with Joey (Estimator) and Jessica (Office contact) and the fellows who did the roofing work was pleasant and straightforward. We are pleased with the quality of the roof and the quality of the work performed. An interesting tidbit: others in the neighborhood stopped by and wrote down the company's name and contact info.

I was there on business. But this is a real good company.

Great company to work with. Jarrod is very knowledgeable. Oscar and crew did a great job with the installation. On time and affordable. Thanks Hays Roofing !
