Heavy rain and strong winds created a leak at my rental property in Honolulu. My tenants weren’t too thrilled about it. I needed immediate service since I wasn’t able to diagnose the problem myself. The leak was coming in over my flat roof but it turns out that the water was coming in at the pitched shingle roof and flowing down hill and under the flat roofing material/system. MRC was able to determine this cause within their first inspection. They tarped my roof for free until they could schedule the reroofing project for a later date, which was a life saver because it kept raining daily. Then when the weather cleared up, they scheduled the job to reroof the shingle section of the house. This stopped the leak and now I have a warranty on my roof and I have happy tenants. I don’t live on island but the communication and pictures that MRC provided throughout the process made it feel as if I was there the whole time. MRC described the whole situation to me. They even threw a little extra silicone water proofing around the skylight curbs just in case. That’s what I call value added service. Don’t hesitate to call MRC Roofing if you have a roof issue.
My new house came with a sneaky little roof leak that created a big problem. The leak was traveling horizontally. MRC was able to determine that a reroof was in order. They removed what turned out to be three layers of roofing and found a lot of rotten lumber that needed to be replaced. They removed the pitch and gravel roofs and installed a new 3-ply CertainTeed modified bitumen cap sheet system. It came with a 20-year material warranty (transferable) and a 7-year leak free workmanship warranty.
I had a leak in my roof under my hot water solar panel. MRC was able to coordinate with my solar contractor so that they could be there at the same time. MRC made sure that the penetrations into my metal roof were sealed properly once the solar was removed. MRC also coated my flat roof with silicone. The communication between MRC, the solar contractor and myself was very good, and the job was done in one day. I am a previous customer of MRC’s and I’m glad that I called them again. One solar contractor that I spoke with told me that the sections of metal roofing under my solar panel needed to be replaced. MRC told me that was incorrect and over kill for such a minor repair. With the money I saved on metal roof panel replacement I was able to put toward coating my flat roof with silicone. A lot of my neighbors have coated their roofs with silicone also instead of tearing off their existing roofs. The nice thing about silicone is that Hawaii’s algae can’t embed into it, which means it will be easy to keep clean in the future. If you’re looking for an honest roofing company. I highly recommend MRC.

We recently had our roof replaced by Protech and we are very pleased with the outcome. The team at Protech did an amazing job and met all the times they promised. We took a long time to finalize the job because of some issues but the team at Protech honored and extended the quote they first gave us. I can't say enough about our contact Jared who we worked with thru the entire process. Jared provided great communication and was very timely with this information with us. The team that did the work was top notch and very professional. We added on a job to add on gutter to the house and that was also a seamless operation with these professionals. The team also did quality work to make the repairs our 60+ year old house desperately needed to prepare for the reroofing job. We contacted 3 roofing companies and no doubt this company is the best in the business. We are very pleased with Protech, Jared and the whole team!
I recently had Protech Roofing blow insulation into my attic. They spent about 3 hours and left without a trace. No mess. I can also say that anyone who has an attic should get insulation as it makes a noticeable difference. I will use AC less often now and when I do, it wont use as much energy. My ceiling was hot during the day before and now it feels very cool. Full disclosure, I worked with Protech on a large commercial project for my day job and they also were very efficient and communicated well which is why I trusted them to help with my personal home.
Protech Roofing is a first rate business. I've been a licensed contractor for 12 years. I can tell when a quality business shows up.They have replaced roofs on 2 properties now with 2 different crews. Both times the job was fast,clean and friendly.Very professional. Charlie's guys are great to work with. Yes ! I would recommend them to everybody ! Go Charlie and Thank You...
