Flat Roof To Sloped Roof Transition

This latest project was in early december in lambeth ontario for a residential home that had an existing sloped or shingled roof that needed to tie into a ne.

Flat roof to sloped roof transition.

A roof pitch transition is a line in the roof plane that changes pitch. Armourfix and armourvalley membranes must be installed and extended 60 90 cm up the main roof underneath the shingles in order to assure a waterproof connection. I want to install a new epdm flat roof. The roof plane goes from one pitch to a lower pitch.

This is a fairly common roof detail. Has had major water damage to the roof decking and insulation that sits below the ib roof system. Flat roofs has also many disadvantages than sloped roofs which are listed below. A very important detail is where the flat roof is connecting the pitch roof.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. This later lead to a lot more drywall damage. Our 4 12 pitched roof transitions to a flat roof on three sides with two valleys feeding into the flat roof on the corners pls see pic we had the flat roof covered with tpo which runs at least a foot up the sloped roof on the three sides. Low slope metal roofs require less material which reduces the overall load on the building s structure.

The starter strip and first row of shingles must be applied 25 cm from the bottom of the slope roof or main roof above the slope transition. Epdm flat roof to sloped roof transition i have a 12x40 rectangular flat roof that is met on all sides by a slate roof. Flat roofs are not always advantageous. Flat roofs aren t architecturally logical as rain and snow will shed much more quickly off a sloped roof.

Disadvantages of flat roofs than sloped roofs. Flat roofs can form. Of course you don t need to live in a modern house to deal with a flat roof. See the illustration below.

Pitch transitions are a common roof detail. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. We are in the process of having a standing seam metal roof installed. Flat roofs are more stable while resisting wind pressure.

We see this quite frequently in log home roofs with porches for example. Yet for historic modern style buildings like this old house s cambridge tv project flat roofs are at the core of the architecture meant to reflect the broad horizontal lines of the natural landscape. We also have a stack that comes out of the flat roof that has caused leaking as well. The distance that the lower roof membrane laps onto the steeper sloped roof and the need for isolation between incompatible materials.
