    I want to replace a wood pole with cement blocks.
    The wood pole is holding up a garage roof beam.
    It is on top of a cement block wall.
    It looks like it can be lifted a few inches to remove the beam.
    I'd need to have rebar support inside the block pole.
    I would need a beam support on the top of the block pole.
    How would I do the top block with the support???

    Is the "garage roof beam", the ridge, and is that the "beam" you want to remove, and why?

    This is a garage roof attached to the house.
    The beam is not being replaced, it's the post at the end.
    It is wood and open to the weather.
    I noticed the bottom is starting to rot.
    Instead of replacing it with another wood pole, I'd like to do something more durable.
    I was thinking of a metal pole, but thinking it would rust.
    Cement blocks seems like a better solusion.

    Is the roof low slope, and sloping from a high to a low point, or does the roof slope both ways away from the beam supported by the post you want to replace?

    In either case the simplest is a powder coated metal pole, with a saddle on the top and a bolt plate on the bottom.

    I was thinking a metal pole would be the easiest to do.
    Just worried about it rusting.

    I wonder if I could cut a street lamp pole to make it work.
    Probably overkill, but most are made of aluminium and won't rust.

    Trying to take a picture.
    Rain and not home.
    I will get to it.
    It's a flat roof with brie roof.
    Pole is holding up an extension, of the beam, holding the garage roof up.
    It was done to remove the original pole holding up the corner of the roof.

    Contact an engineer, because you'll need a structural post.

    I'll check on that.
    I would think a metal pole would be better than a wood one.
    Plus it looks like it would be easier to install.

    Pull nails jack it up change post drop it down replace nails.

    Easier to have steel post engineered, have it built, have it painted pull nails, jack it up remove post, hanger and saddle install steel post drop it down lag bolt the top and anchor the bottom,
    Yeah that sounds easier.

    How long has the wooden post been there? May be that a direct replacement would last for many years, and you have the original to base the specs on. Proper maintenance will also help. As your location looks southern, snow shouldn't be a problem but insects and rain might be.
    But the general instructions will be the same; jack it up just enough to fit in the replacement and lower it back down.

    I'd like to see a wider picture just to see how it ties into the roof and the building.

    If you're worried about rot or rust, how about a galvanized pipe or square tube? Anything wider than the joist it's supporting will create a ledge where water may collect. Then you may have rot up there.

    Post has been there over 10 years.
    Been painted many times.
    Was thinking blocks or metal pole would be less maintenance.
    Getting old.

    You might not need to jack it up. Use a jack to bear the load, cut the old post, slide it out of the steel fittings above and below, slide the new one in, and Viola! Be sure to prime/paint/whatever the new pole on all 6 sides/ends first.
