New slate roof vs. sealant?

My roofer has been replacing some slipped and fallen slate tiles on my Victorian house, as well as some repointing and fixing the ridge tiles. However, he now says the roof is original and the reason the tiles are slipping is because the nails are old and starting to fail (nail fatigue). He's suggested I get a roof sealant called nulife instead of replacing the roof altogether. Will this work, though?

i would never use a roofing selant get it stripped and recovered. in the 70,s and 80,s there was a selant called polar roof i think it was banned as it didn't let the roof breathe and would eventually rot the timbers......if you want to use sealant make sure you have slate vents in your roof for ventilation

i wouldnt seal it, if your nails gave perished so will the felt and battens. these firms that seal roofs are only causing more cost in the long run as they are only hiding the problem, i suggest you get some quotes from local roofers on here with good feedback,

NO NO NO NO Never seal a roof, as it will trap all moisture in culminating in ROTTING OF THE TIMBERS.
As above strip and re slate.
