beam size


i want to put sunroom on back of house 10 feet by 30 feet with 3/10 shed roof style. my concrete patio is only 5 inches thick so need beam to span 30 feet cause can't do supports in middle. i have garage wall at one end for support and can dig support for other end.
What size and what kind of beam do i need?

thanks

Why not? You cut a section out and put a footing in. This is done a every day.

If you insist on going with a 30' beam, no one here on the internet can size that for you. If someone does and you listen that wouldn't be smart and it would be dangerous.You need to have it sized by an architect or engineer.

I was going to mention the same thing about cutting the concrete Joe. I think he wants the beam to span 30' rather than 20'. Good luck with that long span.

It is an exposed ag concrete so it would never match. I figured I would need an engineer but thanks anyways

Can you build up the footing a little higher than the patio and wrap it with stone or something else that's nice looking and set the post on top of that?
