When homeowners in the Winnicutt Road area of Stratham started noticing recurring moisture issues around an aging skylight and several vulnerable roof sections, they contacted Compass Exteriors for a full roof evaluation and long-term solution. After a complete on-roof inspection, our team identified multiple areas where prolonged moisture exposure had caused deterioration to portions of the roof decking surrounding the skylight and several low-ventilation sections of the roof system. Rather than simply covering over the problem, we developed a repair plan focused on restoring the structural integrity of the roof while upgrading the entire system with premium materials built for New England weather. Scope of Work Completed This Stratham roof replacement project included: Full asphalt shingle roof replacement Skylight replacement Partial roof deck replacement in moisture-damaged areas Installation of premium synthetic underlayments High-performance ice and water shield protection Upgraded roofing accessories and ventilation components Architectural shingle installation using Owens Corning TruDefinition® Duration shingles in Slatestone Gray The homeowners selected the Slatestone Gray color for its clean, dimensional appearance that complements many of the classic homes throughout the Stratham and Seacoast NH area. The finished roof added a sharp, updated look while significantly improving weather protection and ventilation performance. Addressing Hidden Moisture Damage the Right Way One of the biggest issues uncovered during this project was concealed decking deterioration around the existing skylight and several previously compromised roof penetrations. This is a common issue we see on older roofs throughout Southern New Hampshire, especially in areas exposed to years of ice dams, improper flashing details, or aging skylights. In many cases, these problems remain hidden until the old roofing materials are removed. Our crew replaced the compromised decking sections to ensure the new roofing system had a solid foundation before installing new waterproofing layers and roofing materials. The skylight area was then rebuilt with updated flashing systems and premium moisture protection to help prevent future leaks and drafts. Why Proper Underlayments Matter in New Hampshire Homes in New Hampshire experience extreme seasonal weather conditions including wind-driven rain, snow loads, freeze-thaw cycles, and ice dam formation. Because of this, we installed premium underlayments and high-quality accessories throughout the roof system instead of relying on builder-grade materials. A properly installed roofing system is about far more than shingles alone. The waterproofing layers beneath the shingles are what often determine how well a roof performs over time during harsh New England winters. For this roof replacement in Stratham, our installation focused heavily on: Leak prevention Ice dam protection Proper ventilation airflow Long-term durability Enhanced flashing protection around roof penetrations and skylights A Cleaner, Stronger Roofing System for the Home The final result was a complete roofing system upgrade that not only improved the home's curb appeal, but also corrected underlying structural concerns that could have become much more serious over time if left unaddressed. Projects like this are a reminder that a roof replacement is also an opportunity to identify and fix hidden problems before they lead to interior water damage, mold, insulation issues, or costly structural repairs.
