CertainTeed Roof Replacement for a Closed-Envelope Attic in Prosper
A home-purchase inspection uncovered premature roof deterioration on this Prosper home. Good Faith Roofing identified non-storm-related shingle blistering associated with its spray-foam-insulated, closed-envelope attic and installed a CertainTeed roofing system. The project was paid in cash, not through insurance.

Why they called us
The customer was purchasing this Prosper home when their home inspector flagged the roof during the inspection period, while the property was still under contract. Their realtor contacted Good Faith Roofing as her trusted roofing source to take a closer look. The buyer needed to understand the roof's condition and the reason for the deterioration before treating it as a routine repair or a potential storm claim.
The problem
Our inspection revealed numerous roofing issues, but none were identified as storm-related. Good Faith Roofing attributed the shingle deterioration to the home's spray-foam-insulated attic, which creates a closed envelope rather than an attic that vents to the outside. On this roof, the inspection identified blistering associated with heat exposure beneath the shingles. Blisters form raised pockets in the asphalt shingle surface; when they rupture, the protective surface is compromised and the underlying asphalt is exposed to weather. The result was premature deterioration rather than the service life the homeowner would normally expect.
Challenges
The central challenge was identifying why the roof was failing, not simply replacing the visible shingles. Because this home's attic was designed as a closed envelope, product selection needed to account for that assembly instead of assuming a conventional ventilated attic. The inspection also needed to distinguish the observed deterioration from hail or wind damage. That distinction mattered to the customer: this was a cash-funded roof replacement, not an insurance restoration. The project's 25 job-site photos also document the complex roof layout, dormer and wall transitions, and underlayment work around the curved turret.
What we did
Good Faith Roofing installed a CertainTeed roofing system selected for this home's closed-envelope attic. The replacement included the roof preparation and synthetic underlayment installation documented in the project gallery, with crews working across the main slopes and turret. The selected system includes 10-year warranty coverage against the type of blistering damage identified on this closed-envelope roof. Coverage is specific to the installed system and subject to the written manufacturer's warranty terms; it is not a blanket promise for every shingle roof or every unvented attic. The completed project addressed the diagnosed roof condition with a system chosen for the home, rather than treating non-storm deterioration as an insurance claim.
