It's amazing how using current materials and colors can transform a house. In this before and after, white aluminum siding was replaced with Mastic Quest Pebblestone Clay Double 4 siding. The black 3-tab shingles were replaced with GAF Timberline HD shingles in Brown
This home got a facelift by replacing the black 3-tab shingles with GAF Timberline HD Brown Shingles.
In the "before picture", areas of rotted decking were found and replaced before re-roofing.
Once old shingles have been removed, close inspection of the existing decking and supports is critical. As structural components of the roof system, they need to be capable of supporting the roof system plus the weight of stored material. If sheathing or supports are deteriorated to the point that the roof structural system is not substantial enough to support recovering, it must be either repaired or replaced. As you can see, the decking on the roof pictured was repairable, saving both time and money.
Both code and manufacturer's warranties dictate that shingles must be applied to a "nailable" surface. Therefore, applying shingles over a rotted substrate is not only unsafe, it will lessen the life span of your shingles and VOID your manufacturer's warranty.
FYI: Because a solid substrate is required by building code, when properly documented with both photos and communication, we have found that most insurance companies will pay the added cost of sheathing as long as the policy has "code upgrades" included and code is enforced in the area.
Several layers of shingles and bad decking removed, rafters replaced and re-roofed in OKC with GAF Timberline HD in pewter gray.
