Full Asphalt Shingle Replacement on a Two-Story Colonial
Project Overview
Complete tear-off and reroof on a 1990s colonial in Clifton after the owners noticed granule loss in the gutters and a small leak above the second-floor bathroom. Roof was approximately 22 years old and past its useful life.
Analysis
On inspection we found heavy granule erosion across the south-facing slopes, several cracked shingles near the valleys, and aging step flashing at the chimney. Decking was solid with the exception of two soft sheets near the rear valley.
Process
Day 1 tear-off and deck inspection. Day 2 underlayment, flashing, and first two slopes shingled. Day 3 remaining slopes, ridge vent, cleanup, and magnetic sweep of property.
Outcome
Roof passed final inspection with a clean attic airflow test. Homeowners received a transferable 50-year GAF System Plus warranty and immediate improvement in attic temperature regulation.
