What is the down side or risk if TU Max is exposed more than 180 days before covered? What is the remedy?
John Stout with Go Roof Tune Up™ answered:
One question would be how (if at all) it would affect your warranty.
TU Max is rated at 90-day exposure.
TU Max Plus is rated at 180-day exposure.
With either of these products, it would be advisable to do a diligent inspection of the underlay prior to installing the surface material (Tile). TU Max has definite repair procedures outlined to best repair cuts, tears or damage caused by traffic, etc. Follow the repair procedures using modified cement and adhesive compatible with TU Max specifications.
If serious UV damage is apparent, it would be advisable to do necessary repair or approved coating to eliminate future failure of the underlay. Check with your roofer to determine if it is TU Max (90 Day) or TU Max Plus (180 day). The product is still good after 180 days.
I hope this information will be of some help to you.
