Just a supplemental answer, some of the other guys will have some suggestions here.
Looking at your sat mount, It looks as if the lower mast is almost vertical and adjustable? The top half angle looks too severe to sleeve in a pipe.
I would go up with a level and see If I could level the mast and if so, lop off the top angle and sleeve in a pipe on what is left of the leveled mast. Measure the "stub" ID and go to a hardware store and see what fits inside somewhat tightly (enough to slide in with tapping or at least no wobble).
Try to get a heavier wall pipe like Schedule 20 or better yet 40. Sleeve it and either clamp it or drill a bolt hole though to keep the inner pipe from slipping and twisting.
Look for water pipe, electrical conduit or fence pipe. Galvanized pipe only, as other pipes can rust making a orange mess streaking on your shingles, and possibly your gutter.
If you cant find a pipe to fit inside snugly, try to slide one on the outside of your existing pipe. If you cant find a pipe that slides in or on snugly, you could Crush the two together by overtightening a proper sized muffler clamp on the outside. you can paint it afterwards because most commonly available clamps rust quickly. Some fencing clamps are galvanized. .
Look for water pipe, electrical conduit or fence pipe. Commercial grade antenna mast at Ace hardware is thin and you could bend it over your knee!
As AD Tech stated, at least 5 feet, 10 feet would not be out of the question, as your antenna is very small representing low wind load.
Try it, it is cheap and quick. And, if that doesn't work, you will select a physical larger antenna that will need roof clearance anyhow.
