How Do You Shingle The Peak Of A Shed
The shed roof is the one that will be having the single sloping side and it requires installing drip edge on shed. If shingling the shed using the three tap shingle, . You can reach a point at which, a top row has to get finished using a new type of the shingle or ridge cap shingle. The ridge cap shingle look square and they have to be layered starting from a top edge or ridge, of a shed roof.
Know where you have to stop adding the tree tab shingles and then switch to the ridge caps.
How To Shingle A Shed Roof Ridge
The tabs of the last row of shingles should come within 5-1/2 of the ridge. Fold the top of the shingle over the ridge. Nail the fold-over to the other roof deck. Once both roof decks have been shingled and ridge has two layers of shingle tops folded over it, youre ready for the finishing touches.
To shingle a roof ridge or hip, it is best to use the tabs from 3-tab shingles. The thicker tabs from architectural shingles tend to crack and not sit flat.
Cut the shingle into 3 equal pieces by extending the tab slot. Cut the upper corners at about 30 degrees, going from the slot indent to the top edge about 2 in at that edge.
Start at the left of the ridge and work to the right or the bottom of the hip and work up. Bend the shingle tab over the ridge or hip, secure with nails 6 up and 1 in from the edge.
The next shingle tab over-laps so only 5-1/2 of the previous tab is exposed. Repeat until the ridge or hip is done.
The last piece is usually only the colored granular tab being nailed over the upper part of the next-to-last shingle tab.

How Many Bundles Of Shingles Per Square
A package of roofing shingles is called a bundle. Laminate or architectural shingles, one of the most common types of roofing shingles, are generally packaged in three bundles per square.
So in the 2400 square foot gable roof example, you would need 72 bundles of shingles .
Here are a couple more examples:

Install 6 Rows Of Asphalt Shingles
The sixth step is to install the first six rows of shingles. Each row of shingles will be offset from the previous row by 6 inches. This prevents water from running down between shingle joints and into the shed.
Start at the same end of the eve that you started the starter strip on and install a full 36 inch long shingle over the starter strip. Maintain the same â” overhang of the drip edge by lining the shingle up with the starter strip.
Each shingle gets 4 nails. One on each end and one above each of the slits. Nails are typically installed â of an inch from the top of the slits and not in the tar strip.
Continue installing the first row using full 36 inch shingles.
Cut the end of the first row before moving to the second row so you will have the reference point for the 3/8 inch overhang when you cut the next few rows of shingles that are installed.
Start the second row with a 6 inch offset from the first row and using full 36 inch long shingle.
Continue installing rows of shingles always starting with the 6 inch offset and letting the ends overhang the rake until you have 6 rows installed.
As you install each row you will visually line it up with the horizontal marks you made on the building paper to keep the rows straight.
Now return to the starting ends of the shingles and install filler pieces. Make sure that the pieces follow the same joint offset pattern as the singles previously installed on the roof.
On the first runs of roofing you will not have much scrap.
Do You Need Underlay For Shed Roof
The roofing underlay can also be called 30 pound felt paper or tar paper. It is important when it comes to putting a roof on a shed. It is a layer which will create the watertight barrier. An underlay can last six month or even less when it is left at the outside elements. The underlay will provide the secondary and the backup waterproof layer in order to stop the water which will make it through an overlapping shingles at the top.
Start at a bottom of a side of a roof and use the underlay horizontally, over the entire top roof. This is what it is called often as the cap nails, green head or red head. They can be used in attaching a felt over the plywood since such nails do have a large nail head and a small tack at its middle. This means that it will not tear or rip away this felt.
While doing diy shed roofing, each nail should be put after 6 inches up to 1 foot. When the first row had been laid and it is attached, you can use a second layer of the felt which will be moving up to a peak. A second layer of a felt, it has to overlap with 6 inches. This should have been pre-market at the felt this means that the builder will have the clear guide in assisting of the lining up of the sheets.

Stick The Bottom Part Of The Underlayment To The Roof Of The House
Install the second course just like the first, using the guidelines on the underlayment to get the correct overlap. When an ice dam forms on a roof , ice and water can work their way up under the shingles and leak back into the house. Also, strong winds can blow rainwater under shingles. Self-stick roofing underlayment can prevent this because it sticks to the roof decking to seal out water. It also seals around nails, which keeps water from leaking through nail holes.
Rolls of self-stick underlayment have a plastic backing so the material won’t stick to itself. The backing is separated down the middle. Line up the lower edge of the roll with the outside of the drip edge. Peel back part of the uppermost backing on the roll, and nail the top corner of the underlayment to the decking. Start pulling the roll across the decking using the backing, making sure the material is lying as flat and as straight as possible as you pull.
You’ll be able to roll out long sections at a time if you have a low-pitched roof, but the underlayment may slip off the eaves on steeper roofs, so roll out no more than 10 ft. there . It’s important to make sure all your underlayment lies flat before you fasten it to the decking. Ripples and lumps can telegraph through the shingles and may be noticeable from the ground.
Install The Drip Edge
Use aluminum nails to attach the drip edge to the front fascia it should overlap at the ends by an inch. The drip edge goes under the roofing felt on the front to ensure moisture isnt trapped.
On the rake fascia, the drip edge goes over the felt to prevent windblown moisture from getting to the wooden deck. Trim the front overlap, wrap it around the rake edge, and nail in place.

Install Step And Dormer Flashing
It’s possible to reuse existing step flashing and dormer flashing, but the best way to get a watertight seal is to tear off the siding in those areas and install new flashing. Start by running self-stick underlayment at least 6 in. up onto the walls. This provides an additional barrier if water does get past the flashing. Cover the front wall first and then work your way up the side wall. Overlap the sidewall underlayment around the corner onto the front wall about 1 in. or so.
Install the shingles right up to the front wall. Cut a couple of inches off the vertical portion of the dormer flashing, and run the horizontal portion past the side wall that same distance. Nail the dormer flashing to both the wall and the shingles.
Make a 1- to 2-in. cut with a tin snips at the bend in the first step flashing. Run a bead of sealant on the corner edge of the dormer flashing, and then run that step flashing past the dormer flashing the same distance you made your cut. Bend the step flashing around the corner onto the dormer flashing with your hammer.
Install your next row of shingles over that first step flashing, then cover that row with a step flashing, and so on. Nail the step flashing to the wall toward the top of the flashing at the end that’s closer to the peak, so the next step flashing in line will cover the nail. Don’t nail them down through the shingles. For information about flashing around chimneys, see Installing Chimney Flashing.
Install The Starter Strip Shingles
The fifth step is to install a row of starter strip shingles. Starter strips are used to help the first row of shingles that sit over the drip edge to stick to the roof without having nail heads showing.
They can be purchased pre-made or you can make them from the regular shingles you purchased to install on the roof. Since most sheds only need a few starter pieces it is typically more economical to cut the starter strips from shingles.
To make a starter strip from regular shingles you will flip a shingle over and cut it lengthwise along the tar strip just above the tops of the factory made slits. Cut enough singles to run along both eves of the shed.
Cut 6 inches off the first starter strip so that the joints in the starter strip row are offset 6 inches from the row of shingles that will go directly on top of it.
The first starter strip installed will be the one that you cut 6 inches off of.
Install the starter strip upside down making sure that the edge with the tar strip is on top of the drip edge.
There should be a 3/8″ overhang over both the eve and rake drip edges. Put a nail every 12 inches, just above the tar strip and 1 inch from the ends.
Continue installing starter strips along the eve drip edge. They should be 36 inches long and the ends are butted against each other.

How To Pick The Right Type And Color Of Roofing Shingles
Picking the right roofing shingle for your shed depends on several factors. Your budget is often the main consideration.
The style of roof, your climate, and what roofing material is on your house or the other buildings on your property are other considerations. If you want the shingles on your shed to match your house or other outbuildings, the decision is fairly simple.
The style and slope of the roof may work better with an architectural shingle or a 3-tab. A 3-tab has a regular pattern the others offer sculpted edges and 3-dimensional finishes. The winds or amount of sun the roof is exposed to may make the heavier dimensional shingle a better choice too. Expect to re-shingle more frequently with a 3-tab than with a higher quality shingle.
The color of shingle you pick is also important. Coordinating the shingle color with the trim, siding, or other finishing on the shed or other buildings is more aesthetically pleasing.
Additionally, dark-colored shingles will absorb solar heat and transfer it into the building. Lighter colors reflect more of the heat. If your shed isnt insulated, you may want to reconsider your color choice.
What Is A Roofing Square
Roof surfaces are measured in squares.
A roofing square is equal to 100 square feet of the roof.
To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 .
This means you would need 24 squares of shingles to cover that roof. Be sure to add 10%-15% to all your material totals for trim allowance .

Install Deck Protection & Starter Shingles
Now it’s time to install the roof deck protection. These roof components act as a weather-proofing and protective barrier between your house and the elements, helping keep water and cold temperatures out.
- Drip edge at the eves. Start by laying roof deck protection, or shingle underlayment, over the decking . Use chalk lines to determine where you’ll lay them.
- Using your cap nails, secure the deck protection to the roof. Overlap each row at least 3 to 4 inches. If you live in an area with inclement weather, you should consider using a special leak barrier protector.
- Then, install new flashing and starter shingles at the edges.
- Nail the drip edge in place using your hammer and roofing nails. Always install flashing around a chimney and other valleys where two roof planes meet as these areas are more prone to leaks if not protected.
Tip: When installing deck protection, work from the bottom to the top of the roof.

Which Material Can I Use For My Shed Roof
Sturdy and waterproof materials are the best for use on a shed roof or garden building. Here at Roofing Superstore, wed recommend using felt, bitumen roof sheets, bitumen shingles, plastic lightweight roof tiles, or wood shingles to secure an attractive, long-term waterproof roof. Transparent or translucent roof sheets are a good choice for lean-tos and some outdoor buildings but youd see the board on the other side of the plastic when fixed to a shed roof so we dont recommend this.
Types Of Roof Shingle Materials
- Asphalt Roof ShinglesAn inexpensive and waterproof sheet made of flexible asphalt material. It is available in a multitude of colors and numerous profiles. The more limited the color and profile, the more expensive.Note: Most asphalt shingles have a fiberglass web and are also known as a composite shingle. Organic shingles are asphalt shingles without a fiberglass web.
- Cedar Roof ShinglesCedar shingles are sawn to form a wedge, and cedar shakes are split to form a wedge and often thicker. They are made from 200 plus year-old trees, so there are fewer knotholes. They are waterproof but require more maintenance, and are more expensive than asphalt shingles. Unless treated they are not fire resistant.
- Metal Roof ShinglesWater and fireproof interlocking galvanized steel or aluminum shingles which are available in a variety of enameled or baked on colors. They are available in a variety of profiles and sizes. More expensive initially, but last longer.
- Synthetic Roof ShinglesA synthetic shingle product made from plastic polymers, dyes and resins that are more durable than asphalt or cedar. They are available in profiles that resemble asphalt shingles, clay, concrete or slate tile, cedar and metal shingles, plus others.
- Rubber Roof ShinglesA shingle made from recycled rubber, mostly tires. Like Composite or synthetic, it is manufactured to resemble cedar, slate, or asphalt shingles.

How To Shingle A Shed With Architectural Shingles
Shingling a roof with architectural shingles is similar to using 3-tab shingles. Begin with a starter strip of shingles.
To make your own starter shingles, cut the shingle at the edge of the middle strip of adhesive. The part you want will have the two wider adhesive strips.
Begin at the left or middle, depending on manufacturers directions. Align the starter shingle so that 3/4 sticks past the drip edge.
The two adhesive strips face against the roof deck, with the cut edge at the drip edge. Nail the starter strip with 1-1/4 galvanized roofing nails in a line 1-1/2 to 3 from the drip edge.
The 4-nail pattern is 1-inch in on each end and about 13-1/4 between the end nails and the middle two nails. The nails should be in a line about 6-1/2 to 7 above the bottom of the tabs. This will ensure the nails catch the doubled shingle edge.
The 6-nail pattern for steep roofs or windy locations is every 8 beginning 1 in from the edge. The nails should be in a line about 6-1/4 up from the tab edges.
Align the first full shingle with the 12 chalk line. Line it up with the left rake edge. Secure with the 4 or 6 nail pattern. Complete the first row.
Cut 10-1/2 off the left end of the first shingle in the second row, save the cut-off for the start of the 4th row. Complete the row aligned to the chalk line 5-inches above the 12 line.
