Are Thicker Shingles Better for Your Roof?

Feb 24, 2022 | Roofing

When you’re looking to get your roof replaced, the last thing you’re probably thinking about is how thick your shingles should be. Not many homeowners even realize that some shingles are thicker than others, let alone consider whether the thickness of a shingle can impact the longevity of their roof.
However, being made aware of this now begs one major question: Are thicker shingles better for your roof?

What’s The Difference Between Three-Tab Shingles And Architectural Shingles?

While the market is loaded with different types of shingles, asphalt shingles tend to be the popular and more cost-efficient choice for homeowners in Pennsylvania. These shingles come in a variety of colors and types, which makes finding the perfect look for your home much easier. There are two main types of asphalt shingles: three-tab shingles and architectural shingles.
The bottom half of each three-tab shingle is cut into three sections, hence its name. These shingles are lightweight compared to their competitors.
Architectural shingles are very similar to the basic three-tab asphalt shingles with two distinct differences: the lower half of each architectural shingle has an extra layer of asphalt and they don’t have tabs. Also called dimensional shingles, these shingles give a roof more depth, increasing curb appeal.

How Do Thick Shingles Benefit A Roof?

The thinner or more brittle your shingles, the higher probability of roof damage early on. While some damage may be covered by the shingle manufacturer’s warranty, you’ll likely find yourself replacing the roof of your home sooner if you opt for shingles like three-tab asphalt rather than architectural shingles.
The extra laminated layer of asphalt on the bottom half of architectural shingles carries with it a number of benefits.

1. Increased durability

Roofing systems that feature metal, clay tile, and slate have zero flexibility. Although they’re tough, their rigidity also makes them brittle. Unlike those types of roofing systems, both three-tab and architectural shingles are asphalt-based and are reinforced by either fiberglass or organic materials. Their composition makes them more flexible–and affordable–than most other types of shingles and able to better withstand snow and light hailstorms.

2. Protection for the underlayer

Underneath your shingles is either a layer of felt paper or synthetic underlayment. Greenawalt Roofing contractors also install Ice and Water Shield at the eaves and valleys for added protection. Under that is the decking (or plywood). Shingles are meant to protect the paper and plywood against damage from the elements. Architectural shingles are slightly more weighted, which means they can withstand stronger winds than the standard, lighter-weight three-tab shingles.
The proper protection for your roof decking helps prevent leakage that can damage the trusses and ultimately, the structural integrity of your roof overall. It also keeps vaulted ceilings and priceless attic treasures safe, so you can be confident in their quality when it’s time to hand those old toys down to your little ones or your children’s children.

3. Reduced long-term costs associated with roof repair and replacement
