How not to do a downspout

How not to install downspouts Toronto This picture pretty much speaks for itself. You can not have proper functioning eavestroughs if there is a restriction with a downspout. In this case the company that did this handywork may not have realized how this entire system was basically shut down due to how the downspout was squeezed and jammed into the small galvanized downspout that goes through the roof. We had to redirect this downspout completely as the pipe through the roof was way too small.
Performance of an eavestroughing system can be jeopardized and prevented from flowing properly as a result from leaves caught in the downspout and also using downspouts that are too small for the square footage of the roof.
Downspouts of proper size and clear of debris are key to controlling water around your property.

A Very Well Known Toronto Eavestrough Company Did This!

Brackest on eavestroughs shoddy work
Just a quick entry here to display some more handy work of a well known roofing and eavestrough company here in Toronto. Now I don't want this blog to be focused on just other contractors shoddy work but I have been seeing so much of it lately that I feel compelled to share some of it.

I think some companies forget that they are only as good as their last job.

In the top picture the fasteners that hold the eavestrough on are about 4 feet apart when they should be no more than 2 feet apart.


Shoddy work Toronto This same piece of eavestrough was cut a couple of inches too short and instead of making a new piece they inserted a filler piece which doesn't look so nice and may be prone to leak.



Messy caulking job done other company This picture shows a mess of caulking that needed to be spread out to cover the extra seams created by the eavestrough being too short.

This Scarborough homeowner has paid top dollar for her eavestroughs and will have to live with eavestroughs like this for many years to come as like most people cannot afford to do them all over again.

I advise homeowners to educate themselves before going ahead and hiring a contractor. I realize this can be difficult as everyone is always claiming to be the best at what they do. Take some time to do some research on the task at hand and the contractor as well. Ask lots of questions and see how they respond. Do they have the patience or interest to spend some time with you answering your questions? Do they know their product inside out and backwards? Do they seem passionate about their work? I believe that if you do not rush the process and invest some time on your end, it will pay dividends. Visit our website at http://www.eavestrough.ca/

Flashing - What is it?

Flashing Eavestroughing properly installed gutter Toronto Flashing is a strip of aluminum that is installed for a couple of different reasons. It can be used to bridge the gap between the metal drip edge under the first row shingles and the top of the eavestrough.(picture on left)

The picture here (to the left) of a home in North York, shows a large gap of wood fascia that is vulnerable to water damage and leaks behind the eavestrough. Usually the gap is not this big but regardless of the size it's important to consider covering none the less. Often the wood is not even painted and may never get painted as most painters do not paint above the eavestrough. If you have aluminum fascia and it extends well up under the shingles then there is no fear of rotting wood, but you still may have drips between the fascia and eavestrough.

Shown here is a simple piece of aluminum flashing.

Flashing is also installed to prevent water from running behind your new eavestroughs due to shingles that may be curled down. (Curled down shingles can be prevented if the roofing company uses a drip edge, which we highly recommend. Do not allow a roofing company to leave the shingles extra long and let them fold down into the eavestrough.) It's surprising how many roofing companies think this is acceptable. Here is the link to our blog post explaining drip edge: http://torontoeavestroughing.blogspot.ca/2010/03/drip-edge-why-its-critical.html

Here is a picture of shingles that have curled down on a home in Scarborough.

When these shingles were new, they were not curled like this and did not let water run behind the eavestrough like it does in the picture below. Many years in the sun allows them to curl down under their own weight. Since eavestroughs are not actually sealed/caulked to the wood or aluminum fascia, proper water flow into the eavestrough depends on proper shingle overhang.

Below we show how the piece of flashing extends over the back of the eavestrough and up under the curled shingles.

The metal flashing must slide up under the drip edge (if you have drip edge) or curled shingles and extend down over the back of the eavestrough.

FAQ : How much flashing will I need? If you need to flash an existing eavestrough system then a simple inspection will reveal how many feet you need. The places where the shingles curl down and overlap the back of the eavestrough will not need flashing.  When we price flashing with a new eavestrough system we allow a per foot price as there is no way of determining how much is needed before the new system is in place. This is because there is no way of determining when the eavestroughs will come out from under the curled shingles due to the way the eavestroughs slope down to the downspouts. An average home may need 40 to 100 feet to prevent drips if the shingles are curled down. Flashing starts at $2. per lineal foot depending on installation difficulty.

This video shows how water runs off a shingle. It refers to drip edge but once the shingles have curled down it's easier and cheaper to resolve the problem with flashing. Sometimes the curled shingles do not lift easily (they become brittle or stiff and may crack if lifted) to slide a drip edge onto the roof deck. Flashing is easier and will reduce the chance of damaging the shingles when the metal is being installed.
