Gutters are one line of defence against water pooling around your foundation. They direct water flowing down your roof to the downspouts and out to the ground, or a rain barrel or weeping tile.
Principal Roofing and Exterior Contractors is a full-service gutter contractor specializing in the installation, repair, replacement, and maintenance of eavestroughs for residential and commercial projects in Aurora, Newmarket and surrounding areas. We are happy to offer free estimates for your project.


Aluminum seamless gutters are the best option as it reduces the number of seams that water can find its way out of over time. The aluminum comes in a variety of different colours. Whether you are looking to replace them but keep the same colour or change the colour entirely, we can provide you with samples to assist you with your choice.
We do recommend replacing your Eaves System around the 20-25 year mark or if you have the “spiked” method. We install using brackets that are screwed in, rather than nailed in. They are also attached at both the front and the back of the eavestrough, creating greater strength and longevity to your eaves or gutter system.
We install 5-inch and 6-inch gutters. The size required for your home is based on the size of your roof, the steepness or the pitch. Most houses do ok with the 5-inch, but there are certain styles of homes that would benefit from the 6-inch wide gutters. Let our experts guide you through the process of selecting the right size for your home.
Gutter Guards is a common ask as well. It saves you the twice-a-year maintenance on your home.
We install Alu-Rex. This system can be installed on a new eavestrough system or added onto an existing one. You’ll never have to clean your gutters again with Alu-Rex Gutter Guards installed.

We provide free estimates and can assist in creating a drainage plan. We also offer the installation of rain barrels or water collection systems.
