Do decking boards run directly to the House?
The direction in which decking boards run is dependent on the joists. If the deck is attached to the house, then the decking boards will run parallel to the house since the joists must run vertically. In situations where the deck is not attached to the house, the decking boards could run perpendicular.
What direction do you lay decking boards?
The size of the deck Is another factor that determines what direction do you lay decking boards. Dependent on the size of your planned decking, it is desirable to have full length deck boards (with no cuts or joins) that run the entire length or width of the deck.
Is it better to run decking boards parallel or diagonally?
If you run the boards parallel to the width, it tends to give the deck a stumpy look, not very desirable. Again it’s a personal choice, but if your indecisive on which way to run them, If I was to fit your decking I would run them parallel with the longest side.
What type of decking boards should I use?
The materials you use for decking boards will dictate how they are installed, though there are some similarities regardless. Most likely you will use pressure-treated wood planks or Trex-style deck boards. The ‘best’ (and safest) way to lay decking boards is as follows:

What direction do you lay decking boards?
What is the correct way to lay decking? Any decking board manufacturer or professional will tell you: “The proper way to install a decking board is ridge side down.” The ridges are designed to allow for airflow, to stop moisture sitting in the ridge, and allow for a stronger structure.
Do you run deck boards parallel or perpendicular?
Decking running parallel to the house makes the deck look wider and blends the deck into the house. If the decking runs perpendicular, the deck looks long and extending far out, away from the house. Often the house siding also is running the width of the house, and parallel decking reflecting this pattern.
Can you run deck boards in same direction as joists?
You will no longer be able to install the decking parallel to the house because the decking must run over the tops of the joists for support. You will need to either install your decking in the opposite direction of the joists or install the decking at a 45-degree angle.
Should deck boards be butted together?
There is no reason to put a gap between the ends (also known as butt ends or butt joints) of wood deck boards. Wood, both softwood and hardwood, is dimensionally stable in length regardless of temperature, humidity or moisture content. Keep the butt ends as tight as possible when installing wood decking.
Should you stagger deck boards?
Staggering the deck boards decreases the number of screws or nails going into one joist, which can weaken or rot the joist more quickly. Staggering the joints strengthens the deck by spreading the seams across more joists instead of placing the stress on only one.

How far apart should decking supports be?
Decking joists should be spaced at 400mm centres. Structural posts should be positioned no more than 1800mm apart. Use a joist and spirit level to mark the ledger height at the wall. Joists are attached to the ledger or double beam with galvanised joist hangers.

How to change direction of decking boards?
The job involves blocking the joists so you can change the direction of the decking boards from parallel to perpendicular. By installing blocking using joist hangers one by one between the existing parallel joists, you can maintain the same framed structure and still utilize the existing beams.
Why should deck boards be level?
The deck itself should be ‘level’ (apart from the applicable grading) to ensure the safety and stability of the structure. Decking boards are always laid flat side down with a slight gap to allow for both expansion and water run-off.
Does It Matter Which Way You Lay Decking Boards?
Yes, it matters which way you lay decking boards as you must run the boards perpendicular to the joists. Otherwise, the deck will not be structurally sound. If placed parallel to the joists, the boards would not hold sufficient weight and could potentially ‘fall through’ which could cause serious injury.
Should I Flip My Deck Boards?
If your deck is looking old and weathered and you are contemplating replacing the boards with new ones, why not try ‘flipping’ them instead. Not only with this allow you to get a few more years of usage out of them, but it will also save you money as new decking boards are not cheap!
Should Decking be Laid Level?
To encourage water drainage, decks are sloped or graded slightly. No slope is required on decks with properly gapped boards since rain will naturally run off the boards even when level. The deck itself should be ‘level’ (apart from the applicable grading) to ensure the safety and stability of the structure.
What Gap Should You Leave Between Decking Boards?
Leaving slight gaps between decking boards is necessary for expansion/contraction and water drainage. The ideal space or gap is about 1/8” or the diameter of an 8D nail. The best way to maintain consistency is to use a spacer tool throughout the entire deck.
How many inches should a deck be?
For a deck to meet building code requirements, the joists should: be 16 to 24 inches on center, depending on the material of the deck boards you are using. span 1.5 times in feet whatever their depth in inches happens to be. be suitable to the size of the deck – in other words, the bigger the deck, the larger the joists.
Who said running porch decking perpendicular to house and following the pitch away from home is the intent?

Do porches run in the same direction?
but anyway, I think it has to do with the direction of the flooring in the house itself. as porches might be considered part of the house, the joists will run in the same direction, and the flooring oriented perpendicular. that doesn't work for all plans but I think it does for most if you consider that most houses are longer than wide, and the joists will be parallel to the front of the house, usually. hey, lot of maybe/usually's in there!
Why Decking Boards Usually Run Parallel to a House?
Let’s start with this question: Why do decking boards usually run parallel to a house in the first place?
Do you need a structural engineer to build a deck?
Remember, if you’re planning on building a deck, you should always contact a licensed structural engineer prior to construction to confirm the safety of the deck design. Hundreds of decks collapse every year due to poor construction. Don’t be a victim! Get the plans approved first.
Do deck boards run parallel to the house?
On most decks, the decking boards run parallel to the house and across the joists (either perpendicular or at a 45 degree angle). But what if you want to run the decking boards perpendicular to the house, going straight out from a back door? While uncommon and a bit more difficult, achieving this look is possible.
Which direction should decking boards be set on a single carrier beam?
However, the next framing section was most easily built by setting it on a single carrier beam which would run parallel to the house meaning the decking boards on it would also run parallel the house and clash with the existing perpendicular direction of the original framing.
What is the purpose of changing the direction of decking boards?
Changing the direction of decking boards on an existing deck, or a series of multi level decks is a great design technique that can really create subtle but distinct visual interest.
What is a little change in decking?
The beauty of this little change is a series of multi level decks all interconnected and with differing decking direction. The change in the direction of the deck boards really makes each deck its own little area. Almost like its own little room.
Can you see the original decking in the photo?
You can see the original decking in the photo and how the new decking would have to run parallel to the house unless I put blocking in between them.
Does the original deck have a beam?
It was a very small porch and was supported to the house by a metal cantilever bracket. So the original deck did not use any beam. And since the cantilever supports projected perpendicularly from the house the decking boards naturally were perpendicular to the house. Great! That was what we wanted.

Your Own Preference (Design etc).
- Hopefully by now you understand that you can literally run decking boards in any direction you want. Instead of using the horizontal and perpendicular layouts, there other directions you can lay the decking boards.
The cost.
- Be aware that if you decide to go with a design other than a standard layout you will need to re-plan your decking structure. That means adding more joistsand maybe another bearer or two. Adding to the cost of your build, but hey, in my opinion spending that little bit more and falling in love with you deck, then it’s worth it. Same goes if your overhauling a previously built deck.
