Those fiberglass masts need to he guyed. There not that rigid to support the weight and wind loading of a vertical. Guy wires across your roof may not be ideal.

I use I believe to be a 1 inch galvanized pipe slipped inside 1 1/2 pipe both 10 ft long to create a telescoping most for easier take down, maintenance, tuning, etc.

I drill a hole near the top and bottom of each pipe and it's secured with a long bolt at the bottom so its locked in place at full length and I remove the bolt and replace it in the top hole so it doesn't slip all the way inside the larger pipe when retracted.

I have this mast attached to the eave of the house with brackets. The mast is 18 ft high so it has plenty of support with no guy wires needed. I run a Maco 3 element and have no issues. 18 ft is good minimum height for 10/11 meters. Any higher for the mast and you'll most likely need guy wires. For DX it’s just fine, local work depending on terrain and other factors it maybe marginal.

Something like this may work for you if you don't mind attaching a mast to your house. You already have a high roof line so you have a good starting point to add more height without guy wires.
