This free roof pitch calculator will take your roof width see the picture and rise the height of the roof and will calculate the roof pitch both as numeric value.
Punch change angle of shed roof.
If you are only trying to keep a wood pile dry or storing a few outdoor tools and light machinery out of the weather then you might consider a simple single pitch roof since most everything inside will be stored at ground level and pulled out from the outside of the shed.
To scribe the angle we placed a length of stock on top of the rafter peaks and leveled it across using a scrap block to trace the angle.
A flat roof is more likely to allow rain to pool and this can cause damage especially if the roof is made of a porous substance like wood.
The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12.
The amount of shear is a judgment based on the size of the punch the metal type and the metal thickness.
Roofing felt drip edge shingle.
Acceptable flat roof coverings include tin roof sheets and pre fabricated plastic sheets.
Much depends on what your intended use for the shed actually is.
The roof pitch is determined by the rise and run of the roof.
You can always purchase a handy roof pitch and angle finder device to determine the roof slope.
Shingling a wooden storage shed roof is important for a great looking and long lasting shed.
For this project you will need.
A rooftop style cutting shear is desirable.
An unbalanced shear angle can cause the punch to deflect upon contact with the metal see figure 1.
Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the dropped structural ridge to the apex of the sleepers.
Your shed roof pitch may also be influenced by your project specific requirements to let light into the building through the roof or create storage space in the roof void.
A roof with a slope of 10 degrees 2 12 or less is generally considered a flat roof.
Too much deflection can cause the punch to break or interfere with the lower cutting sections.
Whichever roof pitch you choose make sure that you select a roof covering that is designed to be waterproof at the angle that you eventually select.
In the case of a shed roof a layer of roofing felt usually offsets the porosity of the wood.
