To do this begin on one end of the ridge and place the ridge cap so that the asphalt portion points towards the end of the ridge and the adhesive points in towards the center of the roof.
Flashing a slingle pitch roof.
Pitch pan flashing it is very common to install pipes or other penetrations for supports through the roof surface.
Step 1 use prefabricated mono trusses for the easiest and best framing on a single slope roof.
Standard sizing calls for a 6 inch wide roof leg and a 4 inch drop leg with a 1 2 inch drip bend at the bottom.
The pitch pan can be fabricated from metal or plastic.
If single piece flashing is to be used according to mr.
If you look here at the lower slope roof you can see that we ve already put panel on it and installed z trim as we have been doing elsewhere on this project.
Select an angle of slope away from a house into an area with good drainage.
Using aluminum flashing as a connector between the lean to and adjacent structure is an even better way to waterproof the roof of your shed and the adjoining wall.
Protect the eave from ice dams and sideways rain step one in steep slope roofing is the edge flashing.
Typically these supports are flashed in with a rectangular box that is referred to as a pitch pan.
Although this solution is more likely to produce a solid long term result it does require a little more work than simply applying sealant along the top edge.
Roof flashing is a thin material usually galvanized steel that professional roofers use to direct water away from critical areas of the roof wherever the roof plane meets a vertical surface like a wall or a dormer.
Measure the outline of the structure to be roofed with a tape measure or get dimensions from a house plan.
The piece that s going to allow us to join the panels on the lower slope and the panels on the higher slope is the pitch transition flashing or the pitch change trim.
It s the same piece.
I adjust the angle between the roof and drop legs to match the slope of the roof.
The key to a good single slope roof is strong framing underneath.
One common method is to lay the edge metal under the eaves membrane and over the rake image.
This type of detail is common with all membrane systems and installation is similar with all of them.
For pitched roofs regardless of the application or type of flashing used the purpose of flashing is to direct the flow of water that leaks into the intersection down and away from the interior of the structure to the topside of the roofing material.
I hem the 6 inch edge and the 1 2 inch drip bend to stiffen the flashing and minimize oil canning when it expands.
Drive a nail through the adhesive portion of the ridge cap into the roof decking.
