It's best to precisely slope all the eavestroughs to the corner that has good drainage.
Most homes, in the Toronto area, have good drainage in more than just one area. There are just a few unique situations.
The home below had more than one downspout location but not without depending on the old clay sewer pipes which the homeowner did not want to reuse. There is a good reason for that as they are prone to leaking water around your foundation as they degrade.
We did a full replacement of the old system as shown below.
The entire upper level eavestroughs were graded around to the front and we added a downspout to connect it to the lower eavestrough. This prevents water from running down the roof and damaging shingles.
We added 2 XL 3.5 inch by 3.5 inch downpipes at the front right corner
The water from the entire house will drain to the front yard.
Due to the slope of the ground near the home we had to extend out to a safe exit point.
The video below explains in a bit more detail.
Another home we completed had a similar challenge with only one safe location for a downspout.
With a bit of effort and creative thinking most houses can have an effective eavestrough system which safely transports all roof water to a harmless location. This keeps your basement nice and dry as well as protected.
