Simple really.
Top edge of ridgeboard will be at a height of “total rise” + “height above plate”

Bottom edge of will be at a height of “total rise” + “height above plate” - width of ridgeboard


Let’s use the videoman’s figures for an example:
He had total rise at 20”7/16, height above plate of 4”3/16 and a ridgeboard width of 8” but actually 7”1/4 finished size


So we get top of ridge at 24”5/8th (“total rise” + “height above plate”)


Bottom of ridge at 24”5/8 – 7”1/4 = 17”1/8 (hence the size of the temporary block he used to prop up the end of the ledger).


I'm going to lay down now.




P.S. If there are any chippy's (working or retired) who know a quicker/simpler method please let us amateurs into the secret.

I had to look them up as I had no idea what they were. Although a good idea, thank you, the pictures I found just make me think, cheap and cheerful but for as they are for a shed roof they would do.
I had no idea you could buy them pre made which is silly as I have seen them on lorries.

This was interesting

Thanks COLVERT for the idea

Further to the above post.--A good chippy can fix a set to a large house in half a day.

By the end of the same day the house can have--'Felt and batten'--making it basically water tight.

you have not disagreed with me about cheap and cheerful.
I will not buy a new mas build as I think the construction is poor quality, I dont like concrete/solid floors, plasterboard walls, cables plastered into walls without being in conduit, small gardens, small garages, lack of parking, cheap doors. As for semis and terraced......never again will I buy one and I would not even recommend one.
Cannot say I know much about building but brick walls, suspended floors, solid doors, decent door frames, wide joists, floor boards are my kind of thing.

The truss is a good example of the difference between what I like and what can often be found. I like the rafter as I feel is is a stronger and better construction.

Wife and I are looking to buy a house, via the internet we have probably looked at over 3,000 houses, we have viewed less then 20 externally, less then 10 internally and put offers in on just 5 but other people got the properties. 2 were pretty special. The hunt continues

In the picture below you'll see part of a 40 house site that I was site manager on.

All the houses had trussed rafters. All had electrical chases in the walls in which was fitted electrical conduit.---All the central heating pipework was also hidden.---Suspended floors make homes for vermin and spiders beneath them.----A concrete floor with the correct insulated bed stops all the heat loss you get with suspended floors.---No movement of any internal walls due to floors moving and creaking.---The depth of joists is the main factor not width as they take a vertical load.

All the houses in the picture below were 3 or 4 bedroom detached houses.

True, you can indeed buy trussed rafters (a pain in the eyeballs when you want to do much with the attic space and also a pain if you need to span anything non-standard.) but that wasn't what Mac was after for his job.



For those who have to put up plain old fashioned rafters surely there is some neat, tried and trusted method known to the chippys of old out there?
