    l recently purchased a home in Corvallis & the inspection report noted a new roof would be needed…read morein the next two or three years due to the installation. I had a couple of roofing companies give a bid. My real estate agent has referred Monroy's Roofing to many clients. I appreciated the explanation of choices available & what to expect during this project. My home is close to 2500 sqft. The crew arrived, work was underway before 8:00 a.m. Have a new roof by 4:00 p.m. on day 2. I appreciate the respect for property, putting items moved to do the work, back where it was & blowing off the roof as well as yard, leaving everything clean. Happy to give five stars to Monroy's Roofing Company.

    Monroy's is AMAZING! I got four quotes for the total re-roof my home needed- including full plywood…read moresheathing. Not only was Monroy's the most economical estimate, but as soon as I met Genaro I knew I wanted him and his crew to do the job. They came ready to rock on a Friday morning at 8am and got my 1300sq ft house completed within two days! The crew were courteous, attentive, and professional. Genaro was on site working hard alongside his guys, Chris was also on site to help and provided me with drone photos after the first day of work. My roof looks amazing and I am 100% confident in their craftsmanship as well as the high quality materials they worked with to get my home water tight and safe again. Thank you SO much to Genaro, Chris, Mario, Hilario, Jesus, and Noe- and the other guys whose names I didn't get. I really appreciate your very hard work and attention to detail and clean up.

    The company charged me 495.99 to resolve my issue with water flowing over their gutter covers. 3…read moreworkers cleared off debris (leaves and pine needles) collected in corners. Total time was 20 minutes per worker. One hour if you add their times. A few days followed, and I received a call asking if I was satisfied with the work. I stated that I felt the charge was excessive for the effort involved. They agreed that the estimate was excessive, and she would bring it up at the next meeting. Removing the debris has helped but the gutters are still leaking. DO NOT HIRE THIS COMPANY OR YOU WILL REGRET IT.

    We hired them to reseal the gutter corners of our one-story house. A crew of two guys came out -…read morethe one who came to the door was not wearing a mask (I did not see the other). Based on the estimate, we assumed the job would involve quite a bit of work, but they were gone in under an hour. It equated to billing out at roughly $450.00/hour (forget about med school, kids -- sealing gutters is where the money's at). The team finished so fast, we called the office to request a supervisor come inspect the work, to ensure it was done properly. Oregon Gutter Service requires you to put down a 50% deposit to schedule the work, even for jobs that don't require much in terms of materials. They ask you to pre-authorize payment of the balance upon completion of the job - something we don't remember being asked for or authorizing but they say they did. Either way, they should have held the payment until we'd had a chance to finish our inquiry ... but they did not, they charged our card later that day. Over the next few days we spoke with several employees. To their credit all were courteous, and calls were returned promptly. The estimator came out per our request and photographed each corner to document the work that'd been performed. The quality of the work was acceptable. So in the end it was a case of caveat emptor. We should have made sure we fully understood the scope of work before accepting the bid, to ensure we were comfortable with the cost. We should have questioned them closely about their payment terms and their COVID policies. This was an instance of our poor judgement - if we don't like the company's policies, we should choose not to do business with them. Pros - They did a reasonable job. - They did it within the time window promised when the job was scheduled. - They returned calls promptly and were polite. - They sent someone to inspect the work and provided photographic documentation upon request. Cons - Workers don't wear masks. We've since learned that the company has no policy re: wearing masks to ensure customer safety. - They require a 50% deposit before they'll schedule the work, even for jobs that have minimal materials costs. - They request the right to charge the balance to your card the moment the work is complete (i.e., pre-authorization, no opportunity to inspect the work). Even though we called promptly to request an inspection of the work, they charged the balance to our credit card immediately. - The rates seem quite high for the nature of the work performed.
