“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 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.”
