Sat, 09 Apr 2011 16:49:37 +0000

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.

Flat Roof Rooftop Floating Wood Deck. Toronto Flat Roofing.

Mon, 04 Apr 2011 02:04:54 +0000

Here we install a floating walkout wood deck on a flat roof in Riverdale, Toronto. Last fall we installed the flat roof for our client, this spring we built this roof top deck. This deck is floating with no puncture or penetration of any sort to the roofing membrane as it should be.

Last spring we installed the two-ply modifed bitumen flat roofing system for our client and this spring we installed this floating flat roof deck. The deck was built of pressure treated wood as it will be exposed to the elements. The height and design of the deck were based on the client's request and our suggestions. As you see this deck is floating on styrofoam, so there is no punture or penetration of any sort to the roofing membrane. The deck is entirely stabilized by being attahced to the third storey of the home. Such a deck must be stabilized by being attached to the structure in some form. There are many options available depending on the structure. All specifications are consistent with city code. Scroll down to view the image gallery.

We offer various flat roof decking options, including wood decking as above, wood decking with glass and metal railings and more. When installing a deck be sure that the deck is floating. If there is any puncture to the roofing membrane. The enrtire deck will have to be removed and the leaking roof repaired. This is a costly mistake to endure. For proper flat roof deck installation contact us.

Flat roofing Toronto. Leaking modified bitumen flat roof in Toronto.

Mon, 29 Nov 2010 17:00:09 +0000

We recently installed our two ply modified bitumen SBS flat roofing system on a pair of leaking flat roofs in Cabbagetown, Toronto. The flat roofs were leaking due to improper application of the roofing membranes resulting in both condensation and leakage through the seams. Watch our roofers cut the membrane and expose a roof that appears to be in good condition yet, contains a significant amount of water underneath and between the membranes.

Our Cabbagetown, Toronto client was experiencing serious leakage in the bathroom of his townhouse. Contributing to this leakage were improperly sealed seams along the edge of the roofing membranes. The roofing membranes are to be heat sealed using a propane torch such that the edge of one membrane roll is overlapped and bleeds onto the previously applied membrane roll. This bleed will ensure the roof will not leak. The bleeds on this roof were very small or non-existent which eventually results in the rubber membrane lifting and allowing water to travel under the membranes. Also, improper heating and application of the rubber itself will lead to air pockets between the roof deck and the rubber membranes causing condensation. Both of these issues were the cause of the leakage on this particular roof as is generally the case.

We proceeded to strip the entire roof and install our two-ply modified SBS bitumen flat roofing system, using Soprema 180 base membrane, 250 cap membrane and 1.5 inch poly iso insulation. We also installed a new copper drain with a u flow seal. Uflow seals are designed to be tightened using internal screws which compresses the thermoplastic seal, forcing it to expand and make contact with the wall of the old pipe. This prevents vertical movement and stops water backup damage.
