Well, normally girders are parallel to the house, the joists are perpendicular and the deck boards are parallel. This is because the ledger acts as the a girder against the house supporting the joists. If you run the deck boards perpendicular to the house, then the joists need to be parallel.
Likewise, which way should my deck boards run?
A board that is correctly installed right side up (or bark side down) will form a crown and allow water to run off the edges. If the board is installed wrong side up (or bark side up) it will curve up on the edges when dry and water can gather and sit in the cup. That is a recipe for wood rot and problems.
Subsequently, question is, how do I keep my deck boards straight? Deck Board Spacing with Chalk Set the first board along a chalk line to start straight. Then sight down the boards occasionally to make sure they’re staying straight. If they’re not, vary the size of the gap between boards gradually over a few rows as needed to straighten them.
Moreover, should decking boards be horizontal or vertical?
In what direction should decking boards be placed (horizontal / vertical) compared to the deck? The boards are usually placed horizontally perpendicular to the adjacent wall. This choice is above all aesthetic, but it also important to be sure that the direction of the boards does not hinder water drainage.
Should deck boards overhang?
Allow for Sufficient Overhang of Decking A one to two inch overhang beyond the outer fascia board is sufficient. This means the installed deck boards should have at least 1.75 to 2.75” overhang before the fascia is installed.

How do you install deck boards?
Install decking with 3″ pressure-treated compatible deck screws instead of nails. Use two nails for each joist to deck board connection. Locate screws about 3/4″ from the edges of boards. Start installing deck boards at the outside of the deck and work towards the house wall.
How do you run deck boards diagonally?
Lay the longest span, which is the one that extends from one corner of the deck to the diagonal opposite corner, first. Lay the rest of the decking in two sections, working first in one direction away from the center and then the other. The shortest boards, which fit in the other two corners, go in last.
Should you pre drill deck boards?
Pre-Drilling Holes: The main benefit of pre-drilling holes for deck screws, or any screws, is simply preventing the wood from splitting. Often this is the only way to prevent splitting when driving screws (or nails) close to the end of a board.
What size should deck joists be?
In general terms, joists spaced 16 inches on center can span 1.5 times in feet their depth in inches. A 2×8 up to 12 feet; 2×10 to 15 feet and 2×12 to 18 feet. The larger the deck, the larger the joists.
Is it better to nail or screw deck boards?
Deck screws are the best, hands down. Nails will rise up and create a hazard and they tend to corrode more quickly. Screws are more expensive but hold better and won’t corrode if you use the correct type.
Should you countersink deck screws?
If you are face-driving deck screws, it is acceptable to “self-countersink” them. Some deck screws even have a little cutter head built into the screw, to facilitate countersinking.
How many nails should be on a deck board?
The basic rule of thumb here is 350 screws for every 100 square feet of deck surface for standard 6” wide boards (5.5” actual width) and 16” spaced joists. If you aren’t using these standard sizes, use an online deck calculator to determine how many you’ll need.
How do I make sure my deck boards are square?
Measure the distance from one corner of the ledger board (the rim joist attached to the house) to the opposite corner on the outside of the deck. Then, measure the distance between the opposite two corners. If the two measurements are equal, the deck is square.
Why are deck boards staggered?
Give It a Dry Run and Stagger the Boards Do a dry run of your boards by laying them out before attaching to the frame. If your deck dimensions are longer than your decking boards, staggering the joints is important when laying decking boards. The staggered boards improve stability and the appearance of the deck.
How far should screw decking be from edge?
Professional builders using standard 5 1/2-inch-wide deck boards attach them at each joist with screws set one to two inches from each edge of the board.
