More information is required. Are you just resealing seams, around vents, etc., or sealing the entire roof material?
For the first part I recommend Eternabond sealing tape; follow applications instructions exactly. The
Eternabond library is a great help.
For a complete roof resealing,
Eternabond roof coating can't be beat IMO.
