Eavestrough Cleaning in Markham

An eavestrough packed with leaves and shingle grit stops being drainage and starts being a planter. Water arrives, finds the channel full, and goes over the front edge in a sheet - straight down the wall and into the soil against the foundation. Which is precisely the outcome the eavestrough was installed to prevent. The weight is its own problem. Wet debris is heavy, and a full run pulls hangers loose from the fascia. Once it sags, it holds even more water, which makes it sag further. That cycle is how a cleaning job turns into a repair job. Winter is where it gets expensive. Standing water in a blocked trough freezes solid. Ice adds weight, ice expands into seams, and a frozen trough guarantees that any meltwater coming off the roof has nowhere to go but backwards under the shingles. Most ice dam problems in the GTA have a clogged eavestrough somewhere in their history. And the debris load here is real. Maples, oaks, and the shingle granules that wash down every rainfall build up faster than most owners expect, particularly on properties with mature trees anywhere near the roofline.
