Selecting the Ideal Roofing System for Coastal Homes: TPO vs. Torch-Down

Introduction: Homes and buildings nestled along the coastline, where the invigorating ocean breeze and the beauty of marine layers converge, require roofing systems that can withstand the unique challenges posed by this environment. When it comes to flat roofs within a mile of the ocean, two prominent contenders come to the forefront: Thermoplastic Olefin (TPO) roofing and torch-down roofing. In this article, we'll delve into a detailed comparison of these roofing options and highlight the reasons why TPO stands out as the superior choice. Furthermore, we'll explore the benefits of using DensDeck roof board and insulation foam board in conjunction with TPO roofing to create a reliable and durable roofing solution.

Comparing TPO and Torch-Down Roofing:

TPO Roofing: Thermoplastic Olefin (TPO) roofing has gained substantial traction as a preferred choice for coastal flat roofs. Here's how it stacks up against the competition:

1. Durability: TPO roofing is designed to endure the coastal environment's unique challenges, including exposure to moisture, saltwater, and marine layer. Its resistance to UV radiation and weathering ensures a longer service life, making it an ideal choice for ocean-adjacent structures.
2. Installation: TPO roofing installation involves adhering the membrane to the DensDeck roof board, creating a seamless and watertight barrier. This process ensures that moisture infiltration is minimized, further protecting the roof structure from potential damage.
3. Energy Efficiency: TPO's high solar reflectance rate aids in keeping the building cooler, reducing the need for excessive air conditioning during warm coastal days. This energy-efficient characteristic not only saves on utility bills but also minimizes the building's carbon footprint.
4. Warranty: With a manufacturer and workmanship warranty of 15 years (20 years with added insulation), TPO roofing provides peace of mind for property owners, reflecting its reliability and longevity.

Torch-Down Roofing:Torch-down roofing, also known as modified bitumen roofing, is another contender for coastal flat roofs. While it offers certain benefits, it falls short in some key areas:

1. Waterproofing: Torch-down roofing relies on the application of melted asphalt to create a waterproof barrier. However, the seams and joints in this roofing system can be vulnerable to moisture infiltration over time, especially in the high-humidity coastal environment.
2. Maintenance: Torch-down roofing may require more frequent maintenance due to its susceptibility to wear and tear from exposure to the ocean's elements. Repairs can be labor-intensive and may disrupt the building's routine.

Leveraging DensDeck Roof Board and Insulation Foam Board:

DensDeck Roof Board: DensDeck roof board, used as an underlayment for TPO roofing, contributes to the roofing system's strength and durability. It acts as a protective layer, enhancing the roof's resistance to impacts, punctures, and moisture. This is especially crucial in coastal areas where wind-driven debris and saltwater exposure are common.

Insulation Foam Board: Adding insulation foam board to the TPO roofing system not only improves energy efficiency but also extends the manufacturer and workmanship warranty to 20 years. Insulation minimizes heat transfer, creating a more comfortable indoor environment and reducing the strain on HVAC systems.

Conclusion: For coastal homes and buildings within a mile of the ocean, the choice of roofing system is paramount. While torch-down roofing offers certain advantages, it falls short when compared to the remarkable benefits provided by Thermoplastic Olefin (TPO) roofing. TPO's durability, energy efficiency, and extended warranty, especially when combined with DensDeck roof board and insulation foam board, make it the superior choice for flat roofs in the unique coastal environment. Investing in TPO roofing with these enhancements ensures that your coastal property is well-protected, energy-efficient, and primed for longevity against the ocean's charms and challenges.
