Summary: Homeowners in Michigan face the dual challenge of rising energy costs and misconceptions about foam insulation potentially voiding roof shingle warranties.

Foam insulation offers substantial benefits in terms of energy efficiency and home comfort without compromising shingle integrity. MAG Insulation stands ready to provide expert, reliable service to Michigan homeowners, guiding them towards energy-efficient and comfortable living. Read on to discover the truths about foam insulation, debunk the myths, and understand how you can benefit.


The Truth about Foam Insulation and Shingle Warranties

As a homeowner, one of your primary concerns is maintaining the integrity of your home’s infrastructure while also minimizing energy costs. Foam insulation has gained popularity as an efficient solution to reduce energy bills. However, a persistent myth suggests that using foam insulation under your roof decking could void your roof shingle warranty. Let’s put this misconception to rest with robust evidence and expert insights.

Scientific Evidence Debunks the Myth

Certain shingle companies claim that the use of foam insulation can void their warranties. Such assertions are not rooted in scientific evidence. Research by industry experts, like Allison Bailes and Joseph W. Lstiburek, demonstrates that foam insulation has a negligible impact on the lifespan of shingles. Bailes’ study revealed that foam insulation raises the temperature of shingles by just about 3 degrees, insufficient to affect shingle durability.

Joseph W. Lstiburek, often lauded as the godfather of building science, has conducted extensive studies debunking the myth that foam insulation significantly influences shingle temperatures and longevity. Thus, concerns regarding foam insulation leading to premature shingle wear are unfounded.

Manufacturers’ Stance on Foam Insulation

Different shingle manufacturers have varying positions when it comes to foam insulation. Recognizing where each brand stands can help clarify your decision-making process.

Progressive Manufacturers Embrace Foam Insulation

Several leading shingle manufacturers such as GAF, Owens Corning, Eli, and CertainTeed, acknowledge the benefits of foam insulation. These companies have conducted their own studies and explicitly state that foam insulation does not affect their warranties. This positive stance reassures homeowners that choosing foam insulation won’t jeopardize their roof’s warranty.

Manufacturers Yet to Embrace Foam Insulation

On the other hand, some manufacturers remain skeptical. Atlas Roofing and Tamko continue to caution against foam insulation under the roof deck. Atlas Roofing notably discourages the use of foam insulation, but interestingly, there are no recorded instances of warranty claims being denied due to foam insulation. As of now, Tamko has not updated its stance since 2009, despite ongoing investigations into the potential impact of foam insulation on their shingles.

The Reality of Foam Insulation

Contrary to the unfounded fears, foam insulation neither contributes to roof shingle failures nor voids warranties. Often, the real culprits of roof issues include:

  • Inadequate ventilation
  • Poor installation of shingles
  • Lack of bathroom vents

Foam insulation provides substantial benefits by reducing heating and cooling costs, lowering required energy loads, and enhancing overall home comfort. Its impact on utility bills is remarkable, making it a viable investment for energy-efficiency.

Accurate information is critical for sound decision-making. Misconceptions can lead to unnecessary expenditure and misguided choices. Understanding the scientific evidence and knowing manufacturers’ positions can help homeowners make informed decisions about their insulation needs.
