Hello, I have 27 Years experience Roofing in Winnipeg
Only a Roofer should be clearing snow from your roof as inexperienced people commonly damage roof structures, unfortunately I see it every year. Also, if there’s a fowl odor coming from your drains, you likely need the plumbing stack on your roof cleared of ice buildup.
There is a relatively new product on the market invented by Winnipegger Jim Dobson, called “No Frost Venting”. It just slides into the existing Plumbing stack And the technology takes it from there.
For fast, safe and reliable service Please call, text or email 204-590-6422
Thank you
