What fills gutters in the Gatineau sector
The Gatineau sector mixes mature streets lined with silver maples and ash trees with newer subdivisions where the street trees are only starting to drop real volume. The two produce very different gutters: older streets fill with broad leaves that mat down into a compact layer, while newer areas mostly collect spring maple keys and shingle granules that settle in the downspout elbow.
Two-storey homes with an attached garage, very common here, often run a large roof area into a single downspout. When that one outlet blocks, the whole front of the house overflows during a single downpour.
