Sloped Roof To Flat Roof Transition

We are in the process of having a standing seam metal roof installed.

Sloped roof to flat roof transition.

Epdm flat roof to sloped roof transition. The distance that the lower roof membrane laps onto the steeper sloped roof and the need for isolation between incompatible materials. My building has flat ceilings at both ends with a sloped ceiling over the center portion. This later lead to a lot more drywall damage.

Here is my situation. 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. You ll have a steeper part of your roof turning into a lower slope so there s a steeper pitch up top and a lower pitch on the bottom. I have a 12x40 rectangular flat roof that is met on all sides by a slate roof.

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 am working on finalizing my roof truss order. I want to install a new epdm flat roof. There are two key details for the transition between steep and low slopes.

We re going to do a pitch transition or change. We need to do something where that change happens so the panels can go down and water can come off hit the lower slope and come off the roof. I had assumed this would be how it was done a scissor truss with a flat. It turns out that our flat roof which is the roof over our 4 seasons porch and is an extension of the original house.

A very important detail is where the flat roof is connecting the pitch roof. 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. My truss designer has asked if i want a supplemental flat bottom chord truss to make these transitions. The water runs off the long ends that is flat roof is highest in the middle and slopes to the 40 foot sides.

Has had major water damage to the roof decking and insulation that sits below the ib roof system.
