Multiply the area by the slope.
How to shingle a single pitch roof.
Shed roofs come in all shapes and sizes but we are looking specifically at two types.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Later on we ll investigate the finer points of applying shingles to the top row of a lean to type shed.
A shed roof is one that has a single sloping side.
The recommended minimum roof pitch for shingles is 2 12 or simply two units of vertical rise to every twelve units of horizontal span.
Most metal shingles will be attached to the roof using metal shingle clips but metal.
Select an angle of slope away from a house into an area with good drainage.
If the roof shingles and all accessory roof components are arranged and overlapped with this in mind the roof should successfully shed water.
The short simple answer is 2 12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles.
They provide excellent weather resistance great value and now more than ever a tremendous range of beautiful designs and color blends.
The key to a good single slope roof is strong framing underneath.
Step 1 use prefabricated mono trusses for the easiest and best framing on a single slope roof.
Asphalt shingles continue to be the most widely installed roof covering option in north america.
Slope is calculated as rise over run.
When shingling a shed roof with three tab shingles the standard asphalt covered tar backed shingles used on most residential roofs you will come to a point at which the top row must be finished with another type of shingle i e ridge cap shingles.
For example if the vertical height was 6 inches your slope would be 6 12 or 6 12 or 0 5 expressed as a decimal.
It is important for shingle roofs to function properly and one method of ensuring that this is achieved is to observe the pitch requirements for the shingles.
The result is the total square footage in your roofing project.
How to finish the top edge of a shed roof.
Understand the physics of how a sloped shingle roof works.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
Single slope and lean to.
