After receiving several quotes for my eaves that left me with sticker shock I noticed a crew from Professional Roofers working on my street. The workers were friendly and gave me a company card. Checked with the neighbour and they were very satisfied with the completed job. The quote I received was more reasonable than the others and the clincher for me is that they don’t contract out, they only work with their in house crews. My finished eaves look great and the crew was pleasant, hardworking and addressed all my Concerns. I highly recommend Professional Roofers. Ask for Patrick to arrange for your quote and property inspection, he’s professional, and a pleasure to work with.Posted on Google![]()

Professional Roofers are amazing! Adam Witte, the estimator helped us out from start to finish. Not the typical pushy Sales person. Walked us through the whole process. Workers came on time and finished in a timely manner. They had a quality control manager Leandro Oliveira, that would come and check the job when it was finished. He made sure all my questions were answered. Dont go with the fly by night roofing companies. Would definitely recommend!Posted on Google![]()

Re: Cleaning of Eavestrough/Gutters & Repairs/Sealant - Great job!! 👍 We requested repairs for a fallen Downspout, sealant for dripping corners of eavestrough and cleaning of gutters (removal of debris) We were quoted a fair price and are very pleased with the quality of work and thorough cleaning 👌 Leandro was a pleasure to deal with and his crew were competent and efficient! We will definitely recommend Profesional Roofers and keep them in mind should we require new Eavestroughs or Roof replacement in future. Thank you for great service!Posted on Google![]()

I recently got the flashing on my flat roof repaired. Professional Roofers were great to get this task done. Alfredo was very professional and quick to respond prior to and while the work was being done. They showed up on the scheduled day and worked 12 hours until it was completed. The roofers were pleasant to deal with and very hard working. I would highly recommend them to anyone needing a new roof or repairs.Posted on Google![]()

I had a fantastic experience with Alfredo from Professional Roofers. From the moment he arrived, he was punctual, courteous, and incredibly professional. He quickly assessed the situation and provided a fair, transparent quote without any pressure or upselling. I was impressed by how efficiently he worked and how clearly he explained everything.
