Our Services
Eavestrough & Downspout
The main advantage of installing 6’’ heavy-gauge aluminum eavestroughs is its capacity to handle heavy rain downfalls, eliminating overflow. Moving from a standard 5’’ system to a 6’’ system will allow the installation of larger downspouts and minimize the risk of severe water damage.
Soffit & Fascia
The aluminum-vented soffit is installed to bridge the gap between your home siding and the roofline. We then install custom, maintenance -free aluminum fascia to lock in the soffit and to ensure that the underlying wood is completely protected.
Siding Installation
Siding is installed to protect your house and its foundation from the elements. Before the installation begins, we perform an inspection to ensure the house is adequately insulated. With the wide variety of siding options, any aesthetic can be achieved.
Roofing Installation
We will do an in-depth inspection to determine which type of roof system and product is right for you. Budget, aesthetics and functionality will all be taken into consideration. All of our roof installations will last a minimum of 20 years.
Specialty Work
We can incorporate unique, timeless accent pieces such as a lead-coated copper bay window roof, which will make your house “pop”. We can also apply this theme to your entire house and choose materials such as a slate roof with copper flashing.
Emergency Service
Ontario Downspout Service prides itself on excellent customer service. We will be here for you when you need us the most. To avoid a crisis, we strongly encourage regular maintenance of your roofing, siding and eavestrough systems.

What Our Customers Say
James Dean
It was an absolute pleasure dealing with Mark from start to finish. He replaced our roof, soffit, fascia, eaves and all of the rotted wood. He also installed beautiful copper detailing around our front porch. We wouldn’t hesitate to recommend Mark, he truly goes the extra mile for you.
Janette MacAvoy
We received several quotes before deciding to go with Ontario Downspout Service. What stood out to us was Mark’s customer service, attention to detail and transparency. Mark replaced our roof, soffit, fascia and eavestroughs in a timely manner and left the work site spotless.
