I've been planning my installation based on 24" rafter spacing, but after measuring, I found out my rafters are actually 16" apart. Now I'm wondering if I need to place a mount every 16" instead, which would increase my flashing by about 30%. Initially, I was thinking of installing the mounts every 48" while alternating at 24" between two rails. Is this still possible?

16" spacing is common for framing that needs to support loads like snow or wind. Just make sure your racking system comes with instructions tailored to these considerations; they usually recommend optimal mounting spans that account for local loads.
Yes! Don't forget about the environmental factors where you live—they can change everything.
Honestly, if you were planning on using a 48" spacing before, there's no reason you can't still do that. Skipping two mounts at 16" is essentially the same as skipping one at 24". Just double-check the weight load calculations from your manufacturer to be sure they support your setup.
Exactly! Just make sure the load calculations are solid so you won't run into problems later.
Totally agree! Better to be safe and check those load capabilities.
If you're looking to attach the mounts directly to the rafters, check the manufacturer's recommendations first, as 16" spacing is quite normal for many setups. They usually provide guidelines that can help you with your installation.
Yeah, definitely check! It can make a big difference in how your setup turns out.
Good point. Always best to go by the manufacturer's specs to avoid any issues down the line.
Great advice! Local climate conditions really do affect what you should go with.
