If you want to know how to build a shed roof, the first most important thing to find out is what design is best suited for the climate in which you live. For example, if you live in cold weather and get a lot of snow, make sure that the kind of roof you build is able to handle the snow. If your roof is not strong enough, it can collapse under the weight of the snow. For warmer weather, you want to be sure your roof allows plenty of ventilation so that your shed does not overheat. The bottom line is that you want to make sure that your shed lasts for years to come and continues to protect the contents inside.
One side note, if you live in an area with heavy snowfall; look for plans where the roof pitch is as steep as possible. This will help the snow slide off rather than accumulate. Snow accumulation can reach thousands of pounds, putting a tremendous stress load even on the sturdiest structures.
Once you have your shed plans, check the roof construction and make sure that it conforms to your local building codes. For specific shed building code requirements of your city or town, visit the municipal building department.
Once you know that your roof meets the code requirements, get to your local lumber yard. They will fabricate the necessary roof trusses for you.
Before installing the roof trusses, mark the top plate of the wall every 24 inches on center then place the roof truss on the first mark and nail it into place. Repeat this process for the remaining trusses.
Most roof designs will call for 5/8″ decking to tie the trusses together and to support the roof loads. Install the decking and then cover with asphalt roofing paper and shingles.
Don’t cut corners, go with at least a 20-year shingle and buy a color that matches the shingles on your home’s roof. This will be more pleasing to the eye. It may even be required by your home owner’s association that you do this.
With the right plans in place, building your own shed is very rewarding.
