Last fall, we installed 7 Velux skylights along with our two ply modified bitumen SBS flat roofing system for our client in Cabbagetown, Toronto. We performed 2 new manual venting curb mounted skylight installations and installed 5 other fixed and electric venting curb mounted skylights into an existing A–frame box to which we made modifications. Here you see the installation including all necessary skylight carpentry by our Velux Certified Installers employees.

Our Cabbagetown,Toronto client had an existing skylights box with some skylights that were clearly showing their age and were made of plastic. See the image gallery below. We made modifications to this A-frame box which allowed us to install 5 new Velux skylights. The skylights installed were,

2 Velux VCE Electric Venting Curb Mounted Skylights

3 Velux FCM Fixed Curb Mounted Skylights.

Since, we were installing our two ply modified flat roofing system with 1.5 inch poly-iso insulation, it was a good time to add two more skylights to the roof. The client decided to have us install

2 Velux VCM Manual Venting Curb Mounted Skylights.

We performed all necessary carpentry including framing and curb work. Please scroll down to the image gallery below.

Velux skylights installation on flat roof in Toronto

Our Cabbagetown, Toronto clients were experiencing continuous condensation problems with the large 4 x 8' acrylic dome skylight on their flat roof. To solve this problem M&R Roofing fabricated a custom curb mount "A-shape" frame for their flat roof and mounted two 4 x 4' Velux glass skylights.

Many downtown Toronto homes feature large scale acrylic dome skylights on their flat roofs. In some cases, these skylights can produce an enormous amount of condensation when the warm air that rises from within a home reaches the cold surface of a large skylight. The condensation problems are more likely to occur the larger the skylight. The problems are also more likely with acrylic then glass skylights because of the greater heat loss through the acrylic material. However, glass skylights installed on a flat roof must be installed on an appropriate slope to prevent heavy amounts of snow from mounting on the skylights. Therefore, acrylic skylights which are more likely to produce condensation problems but can be fabricated in a dome shape that fullfills this sloping function are a cheaper and more practical option for large scale flat roof skylight installations. Therefore a trade off exists.

After experiencing condensation problems for some time and attempting several unsuccesful solutions, our clients decided to install two 4 x 4' Velux glass skylights in place of the existing 4 x 8' acrylic dome skylight. In addition to eliminating the condensation problems our clients also wanted to find a solution for reducing the blazing heat that would result in their upper level rooms, especially during the summer months. To attend to this second issue our clients decided to install a (VCE) Velux electric venting curb mount skylight with Comfortplus glass and blackout blinds.

In order to install the Velux skylights according to the manufacturers sloping specifications, we had to fabricate a custom curb mount frame that met these specifications and also met other requirements. The frame was built such that it allows the two 4 x 4' skylights to sit next to each other in place of the existing 4 x 8 ' skylight. To prevent snow from mounting on top of the two skylights and to allow for proper curb mount installation we had fabricated an insulated tunnel in between the skylights. To eliminate potential condensation problems from the frame itself because of the height of the frame required for manufacturers sloping specifications, we insulated the entire frame appropriately. We then installed our two ply modified flat roofing system as shown in the above video.

Below is a photo and photo gallery of the finished product. This particular "A-shape" frame is a custom fabrication by M&R Roofing and another example of the extensive skill set and knowledge of our employees. If you are experiencing similar skylight condensation problems please contact us.
