GAF Timberline HDZ Asphalt Roof Installation | Roslindale, MA, Suffolk County, Greater Boston

About This Roofing Project

For this project in Roslindale, MA, the homeowners faced a costly dilemma: their aging roof—25 years past its prime—was growing concern for leaks and energy loss. As GAF Master Elite Roofing Contractors, Coastal Windows & Exteriors stepped in to provide a top-quality roofing solution. By installing a GAF Timberline HDZ Lifetime Roofing System in the striking Shakewood color, we transformed their home into a stunning showpiece with unbeatable durability.

The old roof was a storm away from disaster, but Coastal came to save the day. Every rainfall brought new surprises—water spots on ceilings, creeping mold in the attic, and skyrocketing energy bills. Shingles curled at the edges, allowing water to seep through and heat to escape. The homeowners could see their money slipping away month after month, and the roof’s worn-out appearance didn’t help the situation. Something had to change—and fast!

Coastal Windows & Exteriors came to the rescue by first addressing structural issues beneath the surface. Rotted sheathing was removed and replaced with sturdy CDX plywood, ensuring a solid foundation for the new roof. From there, our team installed the full GAF Timberline HDZ Roofing System—a 6-layer powerhouse engineered for performance and style.

Here’s what makes this system shine:

  • Leak Barrier: Protects against wind-driven rain and ice dams, keeping vulnerable areas secure.
  • Roof Deck Protection: Blocks moisture infiltration, ensuring long-term durability.
  • Starter Strip Shingles: Prevents shingle blow-offs, laying a clean foundation for the roof.
  • GAF Timberline HDZ Shingles: Durable, weather-resistant, and available in eye-catching colors like Shakewood.
  • Cobra Attic Ventilation: Promotes airflow, reducing heat and moisture buildup.
  • Ridge Cap Shingles: Adds a polished finish and extra protection to high-stress areas.

The improved ventilation keeps the attic dry and the home’s temperature steady. Energy bills? Slashed! Mold and mildew? Gone! And with a 50-year warranty, the homeowners have peace of mind that their investment is built to last.

Project Spotlight: Inside Look on Vinyl Siding Installation

Why did the homeowners decide to replace their old roof with a new one?

The homeowners had reached their breaking point with their leaky, outdated roof. Every storm meant new water stains, puddles, and rising frustration. On top of that, high energy bills and moldy attic corners were yet another worry for their finances and health. They knew it was time for a long-term solution to restore their home’s safety and comfort. GAF asphalt roofs protect what matters most!

What was the condition of the original roof, and how has the new roofing system improved the home?

The original roof was a disaster—shingles were warped, peeling, and letting in water during every passing rainstorm. The attic was damp, musty, and plagued by mildew. Coastal’s GAF roof installation changed everything, adding six protective layers that include leak barriers, roof deck protection, and attic ventilation. Now, the home is dry, energy-efficient, and entirely transformed with a refreshed curb appeal.

What are the 6 layers of a GAF roof system?

  • Leak Barrier: Stops water intrusion in vulnerable spots like eaves and valleys.
  • Roof Deck Protection: Shields the deck from moisture and smooths shingle installation.
  • Starter Strip Shingles: Secures edges and prevents shingle blow-offs.
  • Shingles: Available in striking colors and styles for both protection and beauty.
  • Attic Ventilation: Regulates airflow to reduce heat and moisture buildup.
  • Ridge Cap Shingles: Adds a sleek, finished look while enhancing leak protection.
