It is also easier to insulate a roof with a greater pitch.
Mono pitch roof framing.
Pitch also has its own denotation determined by the rise in inches in 12 inches.
Step 1 use prefabricated mono trusses for the easiest and best framing on a single slope roof.
Also in pairs with their high ends abutting on extremely long spans with a support underneath the high end.
Mono pitched roofs are also known by the names of skillion roofs shed roofs pent roof and lean to roof.
The high back wall below the ridge of the monopitch roof must be braced to the full height of the wall not shown.
Measure the outline of the structure to be roofed with a tape measure or get dimensions from a house plan.
The minimum roof pitch is 1 8 inch rise per foot of span.
Which is equal to 1 4 or 1 3 the total span of the building not counting any overhang.
Common truss configurations for the most widely designed roof shapes.
Figure 1 monopitch roof with full height braced walls.
Roof plane bracing and roof space bracing as alternatives.
The standard roof truss spacing is 2.
Here s my top plate as you can see.
For instance a 4 12 pitch denotes.
Pitch can vary a great deal from a shallow slope up to a very steep pitch.
While the gabled roof is always pitched in two directions the mono pitch always slants in a single direction.
The greater the roof s pitch the better it will shed snow ice and rain.
You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof.
This is the low end we ve extended this end up however as i said in our previous video this is not the best practice.
A sub variation of the mono pitch is known as saw tooth as pictured below.
In this video i just want to quickly show you how you can mark out the position of your birdsmouth on a skillion or flat or what else they call a mono slope mono pitch roof.
Ceiling support framing and dwangs omitted for clarity.
Back then local lumberyards stocked mono slope ridge flashing that looked like oversized drip edge.

Mono used where the roof is required to slope only in one direction.
They differ considerably from the conventional gabled roofs in shape and construction.
The total rise is 12 inches or 1 foot and the span is 4 feet so the pitch would be 1 4 or a quarter pitch roof.
Select an angle of slope away from a house into an area with good drainage and complementary to an existing house or other building.
The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases.
Homes with a mono pitch roof are usually designed with large windows or multiple windows to take advantage of natural light.
Pitch for a gable roof the most common is generally 1 4 or 1 3.
This is the distance between trusses.
