What size should ledger board be?

33
As a general rule, you should use the same size of board for the ledger as you plan to use for the joists. You can use a larger board, however, if it allows for a better connection to the house framing. Calculate the length as 3 inches less than the width of the deck framing.


Besides, can I use 2x6 for ledger board?

2x6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Joist hangers are used to attach the ends of joists to the face of a beam or a ledger board. If you identify a crown in the board, you should always install it upwards.

Likewise, how far can a 2x10 span without support? When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.

Keeping this in view, can a ledger board be two pieces?

You are required to have a minimum of two of those assemblies on your ledger, and your inspector could well consider a two-piece ledger as actually being two ledgers.

How far can a 2x6 Rafter span without support?

How much weight can a 2x6 support?

The type of load in question will also determine how much weight a 2x6 can hold on edge. For example, a 2x4 lumber may hold a 4-cylinder engine comfortably but may not hold a bigger one. On the other end, a 2x6 can support a V8 engine of between 600 – 700 lbs.

Can ledger board extends past House?

If your ledger board will continue around the corner of your house, you will also have to remove the house siding corner post in addition to the siding. Sometimes, you may want to extend your ledger board beyond the house to function as a beam with a post connection at the opposite end.

Does deck ledger need to be one piece?

If possible, you will want to have the ledger be one long piece of stock. However, if the length is over 16' - 18', it may be hard to find a straight piece that long. In this case, two pieces will work. Always try to use pieces that are at least 6' - 8' long.

How many lag bolts do you put in a ledger board?

Traditionally, lag screws have been the most common method of attaching decks to buildings. To properly attach a deck ledger using 1/2" lag screws, 5/16" holes need to be pre-drilled through the ledger and rim joist. After that, a 1/2" hole should be drilled through the ledger only.

Can you put a ledger board over siding?

In order to install the ledger board, you usually need to remove the house's siding. Never install a ledger board over the top of siding no matter what you hear, this can weaken the connection. Aluminum and vinyl siding can easily be removed with tin snips from an area one foot surrounding the ledger board location.

How long should ledger bolts be?

Typically, you will need to install your bolts alternating high and low 2" from the top and bottom of the ledger board. As a rule of thumb, bolts can be spaced 16" on center for supporting joist span up to 12' in length. Longer joists will require tighter bolting patterns.

How do I attach rafters to ledger board?

Attach 2x6 rafters to the house with joist hangers and/or supported by the ledger board. If necessary, use a sliding bevel to determine angles needed where the rafters will meet the ledger board. Rafters are placed on 24" centers, and attached to the beams and settle joists are attached as needed (Image 1).

How do you hang a ledger board by yourself?

Pre-drill a couple of holes in the ledger, then prop it against the house and transfer the holes to the house wall. Remove the ledger, drill the holes through, and insert threaded rod. Hang the ledger off the threaded rod and go to town with the rest of the mounting.

Do I need a permit for a deck not attached to House?

Building Codes offer one reason. According to the International Residential Code², adopted by most states, a deck does not need a building permit if it is “less than 200 square feet, under 30” off the ground, does not serve a required exit door, and is not attached to the dwelling“ — if it is freestanding.

How much weight can a 2x8 support?

some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24" oc and reallllly short spans only (5 or 6 feet ). Most floor loads would be a minimum of 2x8 @ 16" oc and most preferbaly 2x10.

How far can I span a double 2x8?

No, you cannot span 23 feet with conventional lumber, even doubled. It'll be as bouncy as a trampoline and won't meet code, and that's if you can find such lengths. You'll need at least a 12" (nominal) I-joist or an engineered floor truss to span that far, or you'll need an LVL or steel beam midway.
