Recover: If after inspection your existing roof has minimal wet or no insulation on top of your roof in many cases we can save you a great deal of money by leaving your existing roof in place and recovering it with a new membrane. The advantage of this is you save on the cost of disposal and labour to remove the existing roof as well as increasing your R-value with insulation if required. As well, we can still provide you with a workmanship warranty and a manufactures warranty.
Replace: If after inspection we find extensive wet insulation and the possibility of roof deck issues we would recommend replacing the roof as you do not want to cover up wet insulation with no R-value and cover up a potentially rusted or damaged deck which will cost you a great deal more in the long run.
