How to Replace a Rotted Ledger Board or Sill Plate
Grab a flashlight, and take a comprehensive look at your current deck. Do a visual inspection of it each year before your first barbeque. If you spot trouble, fix it or hire a professional carpenter to repair it. If you think there are serious problems with your decking, contact a licensed engineer to both inspect it and provide the proper solution for your decking problem.
Since improperly installed ledger boards are the main cause of deck collapses, do a thorough check on them! Here are some tips on how to examine your ledger board to verify it is safe structurally:. Other causes include badly decayed ledger board.
Since ledger board failure is the top cause of deck collapse, it should be inspected with extra care. In older decks, the ledger board was usually simply face-nailed to the rim joist. More recent codes require lag screws or carriage bolts to be used. If your deck is perpendicular to your dwelling, raise each deck board to expose the ledger.
Make sure the ledger is securely bolted with lag screws or carriage bolts against your house. They should be fastened into solid house framing. The spacing of the bolts is determined by the length of the joists and can vary from deck to deck. Local codes will provide you with more information on proper spacing. Any spacers, siding, or open space decreases the strength of the carriage bolts and may cause the deck to become unsafe.
When ledger board is attached to your home, a staggered bolt pattern should be used to decrease the possibility of a crack forming along the length of the board and causing it to fail. Ledger board may rot prematurely due to lack of proper flashing, or construction with standard lumber.Hi, Guest Login Register.
Read times. Ok so What was a simple pulling of a board to inspect some rot turned into a can of worms. My question is simple: is there a way for me to back this deck off my house while leaving as much in tact as possible? Basically all the structural lumber is still good and want to see if anyone had any nifty tricks on whether I could back the ledger off the house enough with deck structure still attached while I cut out and inspect the rotted sheathing.
I know it sounds crazy. But as to can see the deck was flashed backwards. Yes the flashing goes behind the ledger!! I was going to just reflash it close it up and call it a day but I will alway ls wonder what's going on behind that ledger board if I dont pull it out and inspect.

If it is just that small spot, I know I would just dig out the loose wood, fill it with gobs of caulk, install a new long L flashing under the door opening and put the deck top back on.Key: AdminGlobal ModMod.
Print Thread. When a deck ledger board is installed, and if instead correctly with proper flashing, lag or carriage bolted into the rim joist it is installed directly on the sheathing under the siding.
What happens if down the road the sheathing is rotted for what ever reason and would need to be replaced. Can you just chip it out behind the ledger, but then how would you replace it??

NC - All depends on how things were built Generally you have to be creative and think it out. One house we worked on last year was not flashed, and after 10? I ended up building supports for the floor joists in the basement, then removing just enough of the decking to gain access, then cutting out the rotted section of decking rim joist didn't have to remove ALL of it, and thus the deck stayed in place.
Next off came the siding, and hogging out the rotted sill. Once all bad wood was removed, and surfaces cleaned up, it was a matter of creative rebuilding as well Edited additions: In your instance, you may be able to build a support beam under the deck's joists, remove about 5' worth of decking to gain access to the rimthen cut out the deck rim board so you can get to the siding.

The ledger defines the deck location, width at the building, and height from the ground. The ledger forms the key reference point from which all other deck measurements and plans will be made. Here we describe how to locate and install the deck ledger board.
Wobbly Deck? Improperly Installed Ledger Board is a Common Cause of Deck Collapses
This article series describes critical safe-construction details for decks and porches, including avoiding deck or porch collapse and unsafe deck stairs and railings. The ledger is a board that is bolted to the house to support one end of the deck joists. It is a bit of a hybrid—part foundation, part framing—and installing it is usually the first construction task in deck building.
With the ledger firmly and properly in place, it will be easier to lay out the rest of the foundation. Procedures for installing a ledger vary, depending upon the type of siding on your house.
Watch out : to avoid a dangerous deck collapse the deck ledger board must be correctly connected to the building structure using proper fasteners that tie to the building structure, and the ledger must be properly flashed to prevent rot and insect damage.
To keep snow and water away, the finished surface of the deck should be lower than the interior floor of any room leading onto it. To avoid creating a tripping hazard, the deck can be located an inch or less below the interior floor deck surface 4 to 8 inches below the interior floor. This distance will produce a safe, clearly visible step from the deck up to the house. Your local building code may offer more specific guidelines on this issue.
When determining the height at which to install the ledger, you need to take into account both the drop from the interior floor and the thickness of the decking material you plan to install. 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. This leaves room for the end joists to overlap, and thus hide, the ledger ends. Also, reduce the length of the ledger as needed to allow the decking to overhang the framing. Some types of siding should be cut away to make room for the ledger. Relatively flat siding, how-ever, can remain intact.
Regardless of the type of siding, the strongest ledger connection relies on bolts that run through the ledger and the house sheathing and rim joist, with nuts and washers attached in the basement or crawl space.Preventing and stopping wood rot is one of the most important aspects to consider when building a deck.
Whether building a hardwood, pressure treated or composite deck, trapped moisture and water is the enemy that will shorten the lifespan and compromise the safety of your deck. Our deck flashing tape is a flexible polyethylene waterproof wood flashing and barrier material made with a rubberized asphalt mastic adhesive.
Easily apply this durable, self-adhesive material as flashing to protect deck ledger boards against water. Wrap in-ground wooden deck posts to provide a barrier against fungi and soil moisture. Traditional metal flashing uses nails or screws to secure the top lip to the side of the house thus creating an unsealed hole. Even when covered by house wrap and siding, there is still an unsealed hole into the side of the building. Any nail or screw that might penetrate the deck flashing tape will instantly be sealed around to prevent moisture from ever entering the hole.
Likewise, lag bolts and even staples are automatically sealed to prevent the intrusion of moisture. Simply peel and stick to ledger boards and deck posts to immediately create an effective moisture barrier against premature wood rot and degradation. By blocking moisture and preventing wood rot, the lifespan of your deck is maximized.
The use of a metal ledger flashing cap over the ledger board crown is not needed unless required by local building code. Likewise, apply to all in-ground deck posts that need moisture protection including mailbox posts, fence posts, or deck framing supports. In order to be eligible to make a warranty claim, you must complete the registration for warranty here: www. When this ledger tape flashing is applied over ledger boards it creates a waterproof barrier that trains water to move over the board and drip down.
Wood rot is caused when moisture is allowed to seep between lumber boards and whatever it is attached to. Degradation of in-ground decking posts is caused by fungal growth when soil comes in contact with unprotected wooden posts. This can even occur when the deck post is in a concrete base.
Rot typically occurs down to six inches below grade level. It can be used to protect all in-ground posts from mailbox posts to fencing posts. Wood decay will also occur when deck screws or nails penetrate the deck board surface, piercing the joist sub-framing below.
Simply slit the tape into 4 inch wide strips to cover the tops of multiple deck joists. It will also assist as a noise dampening membrane between deck boards and the sub-framing. Determine the length of tape needed then cut off any extra. To determine the proper location on the post for produc placement, insert the post in the hole, mark the post indicating the grade level, and then remove the post from the hole.
Remove release paper and wrap around post while firmly pressing in place. To maximize adhesion, roll with a small hand roller.
