How far apart do you put boards for porch roof.

Most are spaced between 18 26 inches apart.
Putting the trusses into place.
A 4 by 10 can usually span up to 12 feet between posts.
Measure the section of the roof from the fascia to the peak and divide this by two which is the two foot spacing of the wood nailers.
Common spacing for trusses on this type of building is often between 2 and 4 feet but trusses built with advanced designs may allow spacing as great as 8 or 12 feet.
So the space between rafters can be greater without reducing the maximum span.
Once you ve calculated the number of trusses you will need you should purchase the lumber.
I just want to put up two 6x6 posts with titan wood post anchors either 35 or 70 apart read more.
In my opinion that hazard is uncommon unless your deck users include frequent stiletto heeled shoe wearers.
This table agrees that 10 12ft is the max span for typical grade lumber at typical spacings for a 5psf dead load.
I am building a 10 x12 deck not attached to a ledger board.
There is also a potential trip hazard if the boards are installed so far apart and so wet that as the boards dry in dry climates and weather that their shrinkage opens the gaps to 1 2 or more.
The same concept holds true for roof trusses.
In general the maximum span for a 4 by 6 beam is 6 feet between 4 by 4 posts.
I am looking to install privacy screens on my concrete patio.
If you move up to 4 by 8 you re usually allowed to span up to 10 feet between posts.
The trusses should be a little longer than the exact width to allow for overhang and you will need sufficient trusses to mount across the length.
