We’ve replaced a relatively new roof. Previous roofs here were constantly purely designed and purely installed.
As a result this house did experience various leaking issues over the years, which were not actually resolved with another and another new roof.
We’ve replaced it with GAF EverGuard® TPO 60 mil installed as a fully adhered system, along with total of 7" thick ISO insulation to exceed at that time required R-38 insulation R-Value and with other components and installation details assuring dependency on this roof for long years.
In the process we have also replaced lots of damaged 2x6 tongue and groove (T&G) wood ceiling/roof deck boards.
Existing gutters and downspouts were also replaced with new aluminum seamless gutters and with larger downspouts.
