How to Build a Shed Roof

March 10, 2022

It doesn't matter if you're building a new shed or if you're just re-roofing an old one. To begin, select a shed roof type based on the functions and aesthetics you value most.

Next, take your rafter boards and start measuring, cutting, and setting them up in the proper arrangement. For long-term protection against the weather, all that's left to do is lay plywood sheathing and install your preferred roofing material.

  • Hand saw
  • Combi drill
  • Wood screws
  • Compact saw

the most appropriate materials to use

It's difficult to pick a clear winner among all the numerous types of shed roof materials because each has its advantages and disadvantages.

For a relatively low price, roofing felt is straightforward to install and has a good lifetime. Long-lasting sheet metal is easy to install and reasonably inexpensive. There is only one disadvantage: rust will occur unless it is painted regularly.

While there are many possibilities, these two are your best chances. However, there are a few more things to keep in mind. It's all up to you.

Anyone with a little DIY knowledge can install shed roof felt, which is one of the simplest roofing materials to work with. When installing it appropriately on a shed roof, it is possible to obtain a waterproof membrane that blends in with the surroundings or stands out depending on the felt color you pick. Installing a shed roof is as simple as removing the old substrate and fasteners, then rolling out the felt and nailing it in place.

Shingles

If you're searching for a cheap and attractive way to finish a shed roof, shingles are an excellent choice. There are a wide variety of colors and textures to pick from when it comes to bitumen shingles and wood cedar shingles.

  • Wood shingles

For generations, wood has been used to manufacture roofing shingles, and it is still good material for making shed roofs today.

Cedar, pine, redwood, and western red cedar are the most commonly used woods for roof shingles. They are an excellent option for steep-pitch roofs, and their aesthetic appeal is unmatched.

Although wood shingles are not very fire-resistant, they must be coated with a specific flame retardant in order to prevent them from burning. The best way to be sure that wood shingles may be used on your structure is to verify with your local authorities.

  • Rubber Roofing Shingles

There has been an increase in the use of rubber roofing shingles or composites (which might be plastic, rubber, or a mixture of both). Tile, slate, and shaker-style roofs may all be mimicked with these shingles.

To begin with, the reduced weight of these shingles makes them ideal for use in a variety of applications.

Because of their low weight, you don't have to create as much of a sub-structure with these tiles as you would if you were using ceramic tiles.

In addition to being excellent for the environment, they're also good for the economy. Because of this, rubber roofing tiles may last for a very long time.

Metal roofs

Aluminum, copper, and steel are just a few of the metals available for metal roofing. It's also available in sheets and tiles, so you can design a roof that's beautiful to look at while also being long-lasting.

Metal roofs absorb snow and ice accumulation exceptionally well, are fireproof and are very long-lasting. Many sheets and tile metal roof products are made from recycled materials, making them an environmentally-friendly choice.

Keeping the metal-coated to avoid corrosion and installing rain gutters to accommodate the increased water flow will be necessary.

Plastic roof tiles

Lightweight roof tiles are constructed of recyclable plastic and weigh about 6 kilograms per square meter when installed in strips. Because they're so light, they're easy to place on your shed's roof and don't put any more strain on the shed itself. To create an authentic-looking tiled shed roof finish, the tiles simply fit together like a puzzle.

Clay/concrete tiles

The Mediterranean area of Europe, namely, is the birthplace of both the traditional clay tile and the more contemporary concrete tile. Both of these types of tiles are exceptionally long-lasting and robust, but their weight is a major drawback.

In order to sustain the weight of ceramic or concrete tiles atop your shed, you'll need to develop a very sturdy subsurface.

In addition to a wide range of colors and designs, ceramic and concrete tiles are also very attractive and can be quite expensive.

Styles

Homeowners are more likely to use one of the following three types of framing in their homes:

Pent

When a shed roof frame is planned to be an extension of the main house rather than a stand-alone construction, the pent roof is the most typical option.

Gable

The gable, or pitched roof, is by far the most common and widely used architectural type. It has a single peak in the middle, with two sloping surfaces extending outward from it on either side. A triangle form may be seen in this structure because of the solitary peak's form.

Gambrel

Known as "barn style," the gambrel roof design has long been a staple of American rural communities. Rather than having a single slope on either side of the top, it has two. Because of this, the construction of the roof is a little more difficult, but it contributes to the overall visual attractiveness.

Step-By-Step

To begin building your pitched roof, gather all of the necessary materials and equipment.

The first step is to construct the trusses.

First, you'll need to create the walls and floor of the shed. Then, you'll be ready to build the roof. It is possible to create your own shed trusses with the help of a jig.

It's recommended to build the wooden trusses on the ground rather than on a table or other elevated surface. There's no use in using a jig to ensure that all of your roof trusses are the same because a roof that isn't absolutely uniform will result.

In the end, the number of trusses needed will be determined by the final roof area, which will be uniformly dispersed around the shed.

Shed blueprints usually include instructions on how to put up a roof truss jig and the size of each truss component. Remember that each truss on a pitched roof will have a triangle form as a starting point.

Trusses are normally constructed with an angle at the top of 30 degrees and then a 60-degree angle at the wall. Geometrically speaking, this is the most stable form.

The roof truss members should be inserted into the jig once you have a solid understanding of the general form of each truss. You may then nail the plywood gussets into place.

In order to maintain structural integrity and stiffness, these plywood pieces are required. They may be stored away until all shed walls have been completed before the trusses can be erected.

If you're concerned about the trusses' structural integrity, you may secure them using galvanized screws.

Install and attach the roof trusses.

To support the frame, you must ensure that all wall panels are in place and that the wall is absolutely flat and level at this point. In order to make sure the roof is as tight as possible, some homeowners may add an extra layer of plywood to the walls.

Gable-end trusses are the first to be installed, and they'll take up most of your time. To put it another way, you'll start from the outside and work your way inside, adding trusses from both sides as you go.

To ensure that the trusses are all correctly spaced, it is necessary to take the necessary measurements ahead of time. Then, fasten each truss to the shed's walls using a top nail. Once you raise the trusses into place, they will not remain in place without some help from you.

A horizontal batten brace may be required. Trusses must be securely in place, upright, and attached for the next critical step in the construction process.

Roof sheeting

With the addition of trusses along the length of the shed, you've conceptually created a four-sided building.

The final step is to install the roof sheeting. This, on the other hand, necessitates some forethought.

Soffit boards, rafter end trim, and filler pieces must be installed between the top of the roof plate and the bottom of the roof deck in order to provide enough protection for this roof sheeting.

Roof covering for protection

Most of the time, you'll have to protect the sheets with some form of covering. When storing products that are sensitive to the weather, this is especially important.

Keeping out the cold, rain, and dampness is essential. One layer of roofing felt is often followed by an industrial stapler stapled to the roofing felt, followed by one additional layer of shingles.

In most circumstances, asphalt shingles are a cost-effective and long-lasting option for a roof covering.

FAQ

Which type of shed roof is the simplest to construct?

Roll roofing is also the quickest shed roof to build since it can be rolled out and nailed down in a matter of minutes to cover vast areas.

How do you build a shed roof frame?

A shed roof can be constructed in one of two ways. Traditionally, each board of the rafters, ridge board, collar ties, and ceiling joists is cut and installed one by one. This method has the benefit that the boards may be readily lifted and nailed into position by a single person. This method has the benefit of allowing a single person to quickly lift and nail the boards into position. Ladder work is strenuous, and you'll need to put in long hours.

Another approach is to construct the roof structure on the ground, resulting in individual roof trusses. There are two parallel bottom chords and one horizontal bottom chord in each prefabricated roof truss, which together create the ceiling joists of a building. It's time to raise the trusses, which have been pre-assembled and attach them to the walls with screws, bolts, and other fasteners. Truss installation is quicker and easier than piecemeal framing, but you'll need help moving the trusses into place.

Is it less expensive to construct a shed roof?

It is true that shed roofs are more cost-effective than other types of roofing because of their simple design. When working on a basic roof design with only one slope, contractors find it easier and less time-consuming to complete the project, which results in lower roofing construction costs. Shed roofs were formerly designated only for use on outdoor storage sheds and garages, but that is no longer the case.

Do rafter ties need to be used on a shed roof?

Even if the roof is built with specified trusses or is technically self-supporting, the rafters must be linked together to keep the roof from collapsing. Rafter connections are not present in a normally designed roof, which causes significant structural problems. The ceiling joists are used to construct the rafter ties in the majority of homes.

What is the ideal amount of overhang for a shed's roof?

According to personal preference, the overhang on the eaves and rakes should be between 12" and 18" for eaves and no more than 8" for rakes, respectively. Overhangs, on the other hand, can be extended up to a maximum of 2' in length without the need for extra structural support.

What is the pitch of the roof on a storage shed?

Roofs with an angle ranging from 4:12 to 912 degrees are regarded as typical. These are the most common pitches used in the construction of shed roofs. Once again, the weather is the most important thing to take into consideration.
