Doing Roofing The Cassas Brothers Way!

Mark Cassas of Cassas Bros

Roof Inspection & Assessment

Our process begins with a thorough roof inspection. Our expert team carefully examines the existing roof structure, looking for signs of aging, storm damage, leaks, and structural concerns. This crucial step ensures we develop a tailored replacement plan that addresses the unique needs of the home.

Tear Off old Roofing Material

Out with the old! We completely remove the existing roofing materials—including shingles, underlayment, and nails—down to the deck. This clean tear-off allows us to uncover any hidden issues and start fresh with a solid foundation.
Roof Decking Inspection and Replacement

Roof Decking Inspection & Replacement

With the old layers removed, we perform a detailed inspection of the roof decking. Any compromised or rotted boards are replaced to ensure structural integrity. A strong, level decking is essential for the long-term performance of your new roof.

Installation of Leak Barrier

Next, we install GAF’s WeatherWatch® Ice & Water Shield in vulnerable areas such as valleys, eaves, and around roof penetrations. This self-sealing barrier provides extra protection against wind-driven rain and ice damming—especially critical for Northeast homes.

Synthetic Underlayment

We cover the entire roof deck with a high-performance GAF synthetic underlayment. Unlike traditional felt, this breathable layer adds an extra line of defense against moisture and helps the roof breathe—critical to long-term durability.

Drip Edge & Flashing Installation

Drip edge and flashing components are installed at all roof edges, valleys, and junctions. These metal elements channel water away from fascia boards and prevent leaks where roofing materials meet walls or chimneys.

Starter Strip Shingles Installation

Before installing the main field shingles, we apply GAF Pro-Start® starter strip shingles along the eaves and rakes. These ensure a secure, wind-resistant edge that protects against shingle blow-off and provides a clean finish.

Asphalt Shingle Installation

Now the transformation begins. We install premium GAF Timberline® HDZ™ shingles—America’s #1-selling shingle. These architecturally stylish, high-performance shingles offer lasting protection and curb appeal, with superior wind resistance and advanced LayerLock™ technology.

Ridge Vent and Attic Ventilation

Proper attic ventilation is key to a healthy roof. We install a continuous ridge vent system to ensure balanced airflow and prevent heat/moisture buildup. This promotes energy efficiency and extends the life of your roof.

Final Cleanup and Walkthrough

We treat every home like it’s our own. Once the installation is complete, we conduct a full cleanup—removing nails, debris, and roofing materials from the property. Finally, we perform a final walkthrough with the homeowner to ensure complete satisfaction and answer any questions.
