Are Two Layers of Shingles Better Than One?
While the thought of doubling up on your roof may seem like a boost in durability, the reality is quite different. Choosing to layer shingles can bring forth a host of issues, complicating matters more than they solve.
Leaving the existing layer of shingles in place may offer short-term conveniences and cost savings, but it paves the way for long-term headaches and expenses. Let's look at a few reasons why.
Weight Concerns With a Second Layer of Shingles
Your home's structural integrity is designed to support a single roof, especially in Florida. Whether you opt for 3-tab or laminate shingles, adding a second layer doubles the weight. This excess load can strain the decks supporting your roof, leading to premature wear and potential structural damage.
Selling Your Home?
When it comes time to sell your house, home inspectors scrutinize every detail, including the roof. Having two layers of shingles can raise red flags, impacting your home's inspection results and decreasing its value.
Warranty Issues
Installing a new roof offers the option to purchase extended warranty plans. However, having two layers of shingles can void these warranties due to the heightened risk of damage. The added heat retention from double layers can accelerate shingle deterioration, leaving you responsible for repair costs. And after a major storm? Your insurance company will also have questions!
Multiple Layers Are Less Visually Appealing
Your home's exterior appearance matters and the roof plays a significant role in curb appeal. While you might assume that two layers of shingles would look similar to one, the reality is quite different. Installing new shingles over damaged existing ones can result in an uneven base, leading to a visually unappealing roof on a home that could be hard to sell.
More Problems Down the Road
Opting for two or more layers of shingles presents a myriad of long-term challenges, including:
Complicated repairs: A double-layered roof complicates repairs, making even minor issues more challenging, costly, and time-consuming.
Decreased lifespan: Double-layer roofs have a shorter lifespan due to increased weight, heat retention, and moisture buildup, leading to accelerated deterioration.
Higher removal costs: When it's time for a new roof, removing two layers requires more labor and time.
Make the Right Decision
While removing your roof may involve additional costs upfront, it is standard procedure. It ultimately saves you money in the long run. Consider the implications of maintaining two or more layers of shingles on your home's value and future expenses. With many potential issues arising from layered shingles, it's better to opt for removal before installing a new roof.
