“As a construction professional dealing with Contractors on a daily basis over a 25 year career (Highrise Residential & ICI) I came into selecting a Roofing Contractor for my own residential needs with high expectations. As the need to replace my roof approached and doing research on and off, watching neighbours contractors etc I settled on DeJager. Paul was great to deal with, the quote was timely, informative and price reasonable for the scope of work. The communication on timing and any updates prior to the work beginning were great and the work was even better.
Paul and the guys on his crew were awesome. Hard workers, good workmanship, friendly and conscientious about clean up. This is the way companies should operate and I wanted to share my experience for anyone on the fence. It was also important to me that DeJager is properly insured and follow the Working from Heights requirements. You alway hope you’ve made a good decision, with DeJager I believe you have. I won’t hesitate to recommend DeJager to anyone looking for any of the services they offer.”

“Paul – As you know we shopped for the right material/price to replace our 6000 square foot cedar shake roof for over two years. We looked at every option out there. We met you in 2017 at the Cottage Life show in Toronto. Immediately we were impressed with your knowledgeable straight-talking approach. You came to our home and gave a quote for the job using Euroshield. We quickly came to an agreement that you were the right man for our job. This past June (2018) you and your crew arrived at our home on time and finished the job on time. Our property was left spotless. We are thrilled with our Euroshake roof – using a Canadian-made product with a 50-year guarantee, that looks exactly like cedar shake. We would not hesitate to recommend you and the material you so expertly installed on our home.”

“We all know how hard it is to find a ‘great’ and ‘reputable’ roofing company. I called DeJager Roofing for a quote along with a few others. After meeting them all, we decided on DeJager.”

“I had my roof put on by Dejager Roofing the late fall ,winter of 2024. I got three quotes. Dejager was the lowest. Honestly they were thousands of dollars cheaper than the other two . Why did I decide to go with Dejager roofing? Paul Dejager showed up with product to help me decide what type of roof cover I wanted.. He listened to all my concerns. Answered my questions honestly. Paul corrected my misconceptions. I decided to have Euroshield installed .I liked the warranty ,durability and peace of mind knowing I wouldn’t have to worry again. Ever. Paul, Dirt, Bieber and Matt did an awesome job.You see Paul is not only the boss but he works along side his crew. I needed boards nailed down ,and boards replaced before the could even put down the
the high heat waterproof membrane. They went over the hole roof and ever found a hole left by the last contractor. They did the same for the garage as per our agreement. Dejager Roofing made me see I made the right choice!!! His guys cleaned up all the mess and left my yard in a better state than before they came! Paul contracted his associate to pu t on new eavestrough. No more water issues or worrying is today the day my basement gets flooded. I can’t say enough .I am so thankful to Paul, Dirt ,Bieber and Matt. So if you are in the market for a new roof give DeJager Roofing a call . You won’t regret it! They saved my home and it looks fantastic! Sincerely Ernie !”

“Some neglected older shingling (my fault) on my house had developed a leak that recently became serious interior ceiling damage. Within days of contacting Paul he brought a two man crew who stripped and reshingled one side of a steeply pitched roof in one hot day. His hard-working courteous young men took pride in their work and cleaned up like they were never here. Price was as quoted. This is the third time DeJager Roofing has done work for me, and I have no hesitation in giving them my highest recommendation!”
-Murray Twist
“I met with Paul to discuss having my roof replaced. He was very informative and his experience with the roofing industry was exceptional. He explained the products that he carried and made recommendations specific to my needs. He helped me with shingle type and colouring based on the colour of my home. Paul sent a crew who were extremely polite, friendly and most of all, very experienced. One of the most important things to me was the clean-up. There was not one nail or shingle to be found when the job was complete. All my garden plants/shrubs were covered and potted plants moved when needed. DeJager Roofing insured to protect their workers, which was also important to me.”
