Once you’ve got your four walls erected and your foundation laid, you’ll need a roof for your shed. You start with one single roof beam. This supports that hold up the beam go on the ends, in the middle of each front or rear wall frame. Four end rafters will slope down from that roof beam to the edge of each corner. This creates the angle of the roof.
In-between each of those four rafters you’ll need to equally-space more rafters. Each will be cut at the same angle as the angle that the front and back rafters make to the beam. (If this part sounds daunting, then realize that you can also purchase prefabricated trusses as long as you made the size be a typical size and you did your measurements correct).
More cross-wise noggings are employed to brace the whole roof; and then plywood sheathing boards will cover the roof frame. Once you’re reached this step of the process you can worry less about how weather will destroy or warp your structure.
The roof will then be completed with such things as more lumber members, an underlay of fascia and the roofing material that you’ve chosen to keep the rain out. Again, check on-line for particulars. You’ll have to ensure that no rain enters through he roof, or fungus will form.
Here is where you install the shed doors and shed windows in the spaces that you left for them in the walls. Look on-line for details on how you properly install windows and doors between rafters. Make sure that you have determined exact sizes for your doors and windows, verifying with the store that they carry those particular sizes.
To install the doors and windows you will need to use little wedges which will center the windows between the joists. Place a slanted windowsill, slanting outwards, so that the rain will run off instead of come back into the structure.
To be safe, you can always caulk every crack with latex caulking compound at any point where you fear that rain might come in, and you’re done. The true test will be when you have your first downpour. Remember that you should pick a spot that is not at the lowest area of your property. It should be on higher-ground and the slope should draw rainwater away from the storage shed. If you have built it on skids instead of on a firm concrete foundation it will be easier to move.
If you’re wanting to know how to build a shed roof, that’s basically it. You might put a vent in the roof that has its own built-in fan that turns when the wind blows. This will keep the structure from being outrageously hot during the summer months. If you expect that you might get buildups of hot air in the roof, under the front and back overhang you might put tiny louvered vents.
If you don’t live in an area which has snow, you might consider just having a flat roof. Such places as Arizona and Southern Texas don’t need a pitched roof; but if you live in New York State, you’ll have severe problems if you don’t. And, that’s how to build a shed roof.
