A.J. Long Roofing

In August 2012, I contracted [redacted] (d/b/a [redacted] Roofing) to replace the roof at my residence of [redacted] NH. The roof replacement was completed on August 24th. Based on observing the contractor not use an underlayment, i.e. Tar/Felt paper, under the shingles during installation or more modern synthetic products, I conducted further research and found out that part of my roof was installed improperly by not using a weather proof underlayment and therefor the manufacturer's warranty is invalid. The contract I signed with the contract states that he would '5) Re-shingle with limited lifetime architectural shingles' and that 'all material is warranted as specified by the manufacture.' In fact the improper installation has voided the warrantly on the dormered bathroom section of the roof. Defects deailed below.

Defect #1: As discussed with the contractor on August 30th, the section of roof installed over the dormered bathroom on the backside of the house was not installed with an underlayment. This portion of the roof is considered 'low slope' with a pitch below 4/12 or 18.43 degrees. According to the manufacturer's installation guide for Certainteed Landmark series shingle: “LOW SLOPE UNDERLAYMENT: One layer of WinterGuardTM or its equivalent*, or two layers of 36" (915 mm) wide felt shingle underlayment lapped 19" (485 mm) must be applied over the entire roof.” The manufacturer further states that the limited lifetime warranty is void if the installer fails to install the shingles over the proper underlayment. Since the warranty is now void on that portion of the roof, it is considered defective and must be replaced by you, the installer.

I have further sought the guidance of two separate Certainteed certified installers (named removed). Both companies inspected the work done on the roof. Along with more minor installation errors that were not deemed to affect the warranty of the roof, both contractors advised that the dormered portion over the bathroom was incorrectly installed and would need to be removed and reinstalled as per Certainteed's guidelines. A regional Certainteed Sales and Service representative accompanied the one contractor , and confirmed that this portion of the roof was incorrectly installed and would need to be remediated in order to maintain the Certainteed limited lifetime warranty.

Defect #2: The ridge cap shingles that run along the top of the roof, over the main residence, garage, and the basement walkout, are a different color than the shingles used for the main body of the roof. It is unclear whether they are also a different product line than the main roof shingles. This sentiment was echoed by one certified contractor, who was unsure that they were a Certainteed product. As per our contract, Certainteed Granite Gray shingles should have been used for the entirety of the roof installation.
