I think the roof warranty is void unless you check the roof caulking every 90 days.
Caulk sealing is 1950's technology. Eternabond thick tape has an 11 year warranty, and comes in many different widths.
If you are repairing this yourself, take a look at Henrys Tropi-Cool 887 Elastometric Roof coating. Not that hard to apply, seals up the roof great, also reflects about 94% of summer IR heat, available at local home improvement stores, including special caulk for spot repairs (tree damage, etc.).
Great reviews on Amazon and other places online. Lifetime warranty on this, too
