"I am extremely satisfied with my experience with JF Lopez Roofing. I received 3 other bids for a 30 square roof replacement in southwestern Waukesha County. JF Lopez's price was in the middle but the warranty they offered was top of the line (GAF Golden Pledge), and Mark was able to answer all the questions I had and even included several repair items that the other bidders missed. His knowledge really impressed me and I had no hesitation accepting his bid. The job (which included a 2-layer tearoff and replacement of several deck boards) took a total of 10 hours on a single day in early May 2021. The crew was large and worked like a well-oiled machine. After they left, I double checked the yard for nails and found none (and still haven't to this day). Mark came back the next day to inspect the job and assured me that if I found any issues that I could contact him and he would take care of it. Since I had to install a new antenna on the roof, I had several opportunities to closely inspect the job myself. I found a few aesthetic issues with the flashing that some might consider nit-picking and contacted Mark. He came over a few days later and happily agreed to address the issues I had. A crew came out within a few weeks (I told Mark there was no rush) and everything was taken care of. I will have no hesitation recommending JF Lopez to family and friends."
"JF Lopez Roofing is a great company to work with. We have used their services many times over the past several years for roof repairs. They are always here very promptly and figure out the issues very quickly. Super professional and friendly and do a great job. We are very very pleased."
"Bought a house in NFDL and needed the chimney removed from the roof up. They replaced that section with new roofing and matched the existing shingles."

- "Removed old black shingles. Replaced with nice green shingles. Took care of my roof leaks that the old shingles had. Anything I wasn't happy with Frank was right there to make it good. He values happy customers. Good man to represent his company. Will do business with Lopez Roofing again."
- "Lopez just finished a garage roof replacement. It wasn't a huge job but it was large enough for them to demonstrate their expertise. Front office response, pricing, attention to detail, logistics and efficient completion of the job were all exemplary. I will call them when the house needs replacement. Thanks again."
- "JF Lopez Roofing is the best. I called Mark to give me a quote for a roof on a home and he got it done quickly. The workers got the job done weeks before it needed to be and did a wonderful job! I am in real estate and having a company so professional, timely and do the work with such quality is so important. Nobody better!"
- "I recently had an internship interview there. Let me just say, that was the most uncomfortable interview ever. The co-owner (Mark) of the business assumed I was liberal and asked if I'd be offended if he had Trump signs posted all over the building. He proceeded to tell me that he was thankful for his wife because she put him "in check," otherwise he'd have signs everywhere. I left feeling extremely uncomfortable. I also tried to reach out via email to address the situation but there has been no response. I am disappointed with values and professionalism of this business."
- "We were very impressed with the entire process of replacing our roof with JF Lopez Roofing. The job was done in a timely manner to high standards. The crew worked hard and our new roof looks amazing!"
- "Hired Lopez roofing to repair my commercial rubber roof and replace the gutter. They had been recommended to me by a business associate who I think very highly of. I am happy with the work that was done and the price that had been quoted and billed. I would definitely recommend Lopez Roofing to a friend or business associate."
