Heat blistering is a significant concern for homeowners, particularly during the intense summer months. This phenomenon, akin to skin damage from UV radiation, affects roofing systems, leading to severe structural issues. To effectively combat heat blistering, it’s crucial to understand the three-layer roof system and its vulnerabilities.
Layer 1: The Roof Deck
The roof deck forms the foundational layer of the roofing system. It’s a flat surface that supports the roof’s weight and is typically made of plywood sheets. This layer is crucial as it provides the structural integrity for the entire roofing system.
Layer 2: Underlayment
Serving as a protective barrier, the underlayment is installed before shingles. This layer acts like a tarp, offering an additional shield against water. The most common type of underlayment is felt, designed to prevent moisture from reaching the roof deck, especially if the shingles are compromised.
Layer 3: Shingles
Shingles, the outermost layer, come in various materials like asphalt composite, wood, slate, metal, and clay. Asphalt shingles, popular for residential structures, are particularly susceptible to heat blistering. These shingles can last between 20-30 years, depending on their quality.
The Process of Heat Blistering
Heat blistering occurs when water gets trapped between these layers, causing the shingles to malfunction. In conditions of extreme temperatures and poor ventilation, this trapped moisture leads to the formation of blisters on the shingles. As temperatures rise, these blisters can burst, creating entry points for more water and moisture.
The Risks of Ignoring Heat Blistering
The primary concern with heat blistering is the potential water interaction with nailheads, which secure the shingles. Water can seep through these points into the attic or other home areas, leading to extensive damage. Moreover, blistered shingles can crack and break off, necessitating immediate replacement.
