Why go with All Year? We know our stuff. Here are a few things to consider when getting new eavestrough.
Improperly installed eavestough can usually be put into at least 1 of 3 categories: Slope, Sealant, and Brackets.
Second is Sealant. Not only does the proper product matter, but also how it is applied. Silicone based sealants do not stand up well to UV damage, and will quickly wear down, causing leaks on corners and end caps. Proper care also has to be taken to ensure the caulking is evenly applied, with no air bubbles trapped, or areas where any water can get underneath.
Sealant also has to be applied at the right density. Too thin and it can crack in the winter, while too thick and you are creating a small dam inside the eavestrough.
And lastly is brackets. There are two types commonly used in the Edmonton area. One is a nail that travels through the face of the eavestrough, into a spacer, and then goes through the back of the eavestrough and into the fascia board. The second is a metal mounting bracket that is hidden inside the gutter, with a screw that goes through the back of it into the board.
Although both work, the nails do not have as nice a finish, as you can see the heads very clearly on the face of the exposed eavestrough. They also tend to loosen up away from the fasica board over time, with the expansion and contraction of the wood over winter and summer.
The metal brackets are a much nicer product. They are completely hidden on the inside of the eavestrough for a much cleaner, smoother look. As well as, the mounting screws do not loose their grip over time, and continue to preform year after year. All Year Eavestroughing uses only this type for attaching your gutters.
With both products, it is important that the spacing between them is close as well. Winters can be especially harsh on eavestrough, and they need to be able to support a lot of weight from ice and snow during those months.
