Here are a few podcasts for the garage door industry - mostly targeted at garage door company owners, although some episodes may focus on consumers.
I vetted this list down to just 4 podcasts. While there are a lot of garage door podcasts out there, most don't have actual human 'hosts'. Many are computer voices reading text which isn't of much value. The podcasts below feature human hosts with garage door industry knowledge.
The International Door Association (IDA) has a podcast - the DOOR-CAST - with episodes released fairly regularly, but not on a schedule you could set your watch to.
The Torsion Talk Podcast is a podcast operated by Ryan Lucia from Such n Such Media - a marketing company in Georgia. The podcast has been running for six seasons and regularly releases new episodes of varying lengths - anywhere from a few minutes to over an hour.
This podcast is also hosted by Ryan Lucia - who in addition to running Such n Such media is also the owner of Aaron Overhead Doors in Georgia - northeast of Atlanta.
The International Code Council has the ICC Pulse podcast which covers building safety. Occasionally the podcast covers topics directly relevant to garage doors - including episode 41 - which talks about garage door safety.
