If you are regularly breaking spokes, then the tensions are too low for the load and or riding style. I don’t care what the LBS says. It’s just the facts. The reason that spokes break is either impact by a foreign object (something hitting the wheel, or the wheel hitting something else), or the spoke becomes de-tensioned while riding, causing it to break. There aren’t any other options; other than the wheel is simply aged and has so many miles on it that they really need replacing (on clinchers, this is an immense amount of miles: 20K+ depending on the wheel).
I hope you find the issue. It’s not a fun one!
Raising a glass to your wheel woes; and hoping you have no more.
