Windshield Leak Repair - Roof Cap Lower Edge
I've been reading as many posts as I can find regarding windshield leak repair. Most mention sealing the bottom edge of the roof cap under the reveal molding as well as the roof cap to roof joint.
Is sealing the bottom edge really a good idea? I'm not sure of what's under the roof cap but if water did get under it, say from a leaking roof to cap joint, wouldn't caulking the bottom edge keep the water from draining out?
The sealant callout sheets I've looked at don't show a sealant for this, just for the cap to roof and cap to sidewall. I'm wondering if the bottom joint is left unsealed by the factory on purpose.
