Only covers material and that will be prorated so good luck with getting anything after 2-3 years. OP. sealant failure is unrelated to the roof material. The roof material manufacturer will not cover sealant, sealant failure or lack of maintenance. My previous rig looked like that after 6 years. I used a plastic putty knife and hot air dryer to soften enough to scrape off. The sealant had not cracked all the way through and I think you will find the same thing.
As others said-take no chances and repair soon. Good luck
