CKG Contractors Inc, Installed a new roof in Newton NJ. When the old roof system was taken down all of the wood was rotted. When the roof was originally installed insulation was placed up against plywood. This is a bad idea. A roof needs to breath or you end up with condensation build up under the plywood. When this happens plywood will delaminate and soften. Once this process has begun mold starts forming and rots out the roof from the inside. CKG Contractors Inc, removed all of the rotted plywood and old damaged insulation. We installed new R-19 Insulation and new foam baffles to separate the roof from the insulation. New 5/8 CDX exterior grade plywood was installed. Roof is now protected by our 25-year Titanium workmanship guarantee. Call us for a free estimate on any roofing-siding and window project.
