Eavestroughs are fixed beneath the edges of a roof to collect rain and dispense it away from the home or building. They may seem like a simple piece of equipment, but they protect your roof and foundation from damage and prevent moisture infiltration and mold build up in the attic. In order to get the most out of your eavestroughs, it is important to keep them in good working condition by regularly inspecting and cleaning them. Having an experienced professional conduct a routine inspection and repair is also a good idea to ensure they are functioning properly.
Eavetroughs are also referred to as downpipes or gutters eavestrough and come in a wide range of styles, sizes and materials. Aluminum is the most popular choice for eavestroughs in Canada as it won’t rust and can withstand the cold climate. However, copper and galvanized steel are also common options as they offer superior strength. Some eavestroughs are even hand formed to specific profiles and can be found in heritage or architecturally significant homes and buildings.
Before starting to hang the eavestroughs, it is recommended that you thoroughly inspect the fascia boards to ensure they are in good shape. If necessary they should be replaced with new boards that are free of rot, insect infestation and damage from the elements. It is also recommended that you do not use pressure treated wood as it contains chemicals that can corrode aluminum and other metals.
Start by taking a piece of chalk and marking the fascia board where you plan to install the eavestrough. Mark the first line 3/4″ below the shingle at one end and then make another mark at the other end where the down pipe is located. This will help to ensure that the eavestrough is installed with the proper slope so it can drain properly into the downpipes.
The eavestroughs are fastened to the fascia using brackets or hangers that have a “u” shape and are secured with nails or screws in the wall and at the ends of the trough. A downspout is then inserted into the elbow that is attached to the wall and the down pipe is secured by slotting it into place and screwing in clips every 3′.
Once the eavestrough is assembled it is recommended that you take into consideration the temperature changes and allow for expansion/contraction of the gutters. If necessary, an expansion joint can be added to the trough.
Often it is easiest to start at the top of the house and work your way down the slope; this will minimize the amount of debris you have to move around. When the eavestrough is finished, it should be capped with an aluminum end cap that is crimped or riveted onto the trough. It is a good idea to check the end cap regularly for any leaks or cracks. In addition, it is a good idea to re-caulk any exposed caulking around the gutters. A regular eavestrough maintenance and repair can greatly extend the life of the system and ensure it is functioning properly for years to come.
