Case Study: From Aging Shingles to a Fresh, Waterproof Roof in Maryville

When a homeowner in Maryville, TN, first reached out to us, he was curious about replacing his roof. It had served him well over the years, but signs of age were starting to show: granule loss, algae streaks, and mismatched shingles on the main house and detached garage. The chimney flashing was failing, the chimney cap was in poor condition, and water wasn’t flowing correctly around the chimney. In August, after signing the quote, our team was ready to roll, and we started the project just a week later.

The Challenges

This wasn’t a simple flat roof. The main house was a steep, two-story structure with multiple dormers and valleys, which adds complexity and can slow the installation process overall. Plus, we were replacing two separate buildings: the main house and the detached garage. On top of that, the chimney needed extra attention to prevent water pooling, which meant installing a chimney cricket in addition to a new flashing and custom cap.

The Solution

Here’s what we did to turn this aging roof into a fully functional, long-lasting upgrade:

  • Roof replacement for both the house and the detached garage
  • New chimney flashing and a custom-fabricated chimney cap to fully waterproof the chimney
  • Chimney cricket installation to guide water safely around the chimney base
  • Timberline HDZ shingles in Charcoal and all GAF roof accessories for durability and a cohesive look

The five-person crew completed the project in three days, carefully navigating the steep slopes, intricate dormers, and additional features with near-perfect weather. A project this size typically would take two days to complete, but the two separate buildings, steep 2-story roof, and many valleys made this job more intricate to navigate overall.

The Results

The transformation was immediate:

  • The roof now has a fresh, uniform look across both buildings
  • The chimney is fully protected from water damage with new flashing, a custom-fabricated cap, and a chimney cricket

Chimney repairs can also add additional time to projects, like the cricket and custom chimney cap. The homeowner now has peace of mind knowing the roof is built to last for years to come
