We offer a 3-year workmanship warranty on any of our composition roof installations and a 5-year workmanship warranty on any of our metal roof installations.
This covers any and all leaks that do not come from a manufacturer related defect or weather-related damage.
If it doesn’t leak within those time frames, then the workmanship is good.
There are many companies on the market who offer “lifetime” workmanship warranties, but those are marketing schemes more than true warranties.
Most of those companies don’t tell you that hail damage voids the workmanship warranty and if they go belly-up, your warranty isn’t worth a penny.
