I have sometimes wondered about this, too.

The solution I came up with would be to apply a thin layer of paintable
caulk (DAP Elastomeric Latex Sealant, for instance) over the offending
caulk and then paint it.

Hope this helps.

Roofer used silicone caulk to seal joints between newly installed

when I went to prime the new wood and the paint wouldn't adhere.

Can anything be done to make this paintable, a special sealer or
something; or does the caulk need to be scraped off?

Thanks.
