Did you know that most roofs can have their lives extended by three to five years by doing simple preventative maintenance?  Meaning once a year your roof gets inspected by a professional and any crucial defects can be brought to your attention and corrected properly before a leak occurs and damage is done to your home.  While some projects may simply require a bead of caulking or a missing shingle replacement, others may be at the end of their life expectancy and may require a complete re-roof.


Many roofs today are deteriorating faster and earlier than they should and are not reaching their full life expectancy, mainly due to poor installation methods and lack of ventilation.  


We offer a wide range of preventative maintenance procedures to extend the life of your roof, along with a 24-hr emergency leak investigation service to provide you with peace of mind.  Our expert installers are honest, experienced, safe and certified.

Scott Colson

Colson Roofing Inc. is family owned and operated business.  Scott Colson is founder and CEO of Colson Roofing Inc.  Born and raised in Corner Brook, Newfoundland, he left for Toronto, Ontario just days after completing his education to start what would become his career in the roofing industry.  Eager to learn more about the trade, he would soon discover his undeniable passion for roofing and understanding the science behind it.  While the early years of his career concentrated mainly on flat roofing and waterproofing techniques, education on installations of sloped roofing systems would soon follow.  Throughout the years Scott has worked with large, highly reputable and established companies in both Toronto, and Ottawa, Ontario, which helped him acquired the knowledge and skills necessary to start his own roofing business.  After many years in the commercial roofing sector, commencing in the largest city in Canada, his skill and attention to detail became evident.  He would soon find himself becoming highly intrigued and passionate about waterproofing techniques and procedures.  Once his education and passion had rivaled, his skills and understanding of roofing had constructed him into a respected and recognized name within the trade.
