What Are Composition Shingles

Composite shingle roofing sits on top of the majority of residential homes today. Asphalt shingles will have less of an impact on your wallet, however, composition shingles are significantly more durable than theyre asphalt counterpart and can last up to 50 years before needing to be replaced.

Composition shingles vs asphalt

If youre just starting your search into choosing a roofing material, you might be confused between composition shingles and asphalt, since they have similar characteristics.

The core difference is what theyre constructed from. Asphalt composition shingles are composed of multiple materials such as laminate, fiberglass, wood, and slate. Asphalt shingles are constructed with a paper-like wood base or fiberglass mat with asphalt on top and generally have a lifespan between 15-25 years.

The Weather Conditions Your Composition Roof Is Exposed To


Every roof goes through wear and tear due to weather throughout its life. While climate and temperature play a role, its really about the amount of extreme weather events your area gets.

The more extreme weather that hits your composition roof, the faster the shingles will go through wear and tear. For example, if you live in an area that gets a lot of small hail, then your shingles will have granular loss a lot quicker.

You wont be able to file an insurance claim, but itll definitely shorten your composition roofs life. On the other hand, if you have a heavy hail storm, a tornado, or strong straight-line winds that damage your roof, youll be able to get the problem taken care of through your insurance company.

Hiring A Reputable Roofing Contractor To Install Your Composition Roof

Thats why you need to find a roofing contractor that has a strong installation history. If you hire one that doesnt use correct roofing techniques, your roofs life will be cut short, and youll need a roof replacement well before its time.

No matter if you need repairs or a full roof replacement, your contractor plays a huge role in every aspect of a composition roof.

Maintaining Your Composition Roof

Every roof needs maintenance to keep it running smoothly. This makes getting annual roof maintenance one of the most important factors to ensure you get the most life out of your composition roof.

When you have annual roof maintenance, common roof problems are caught before they can cause too much damage. Its also a way to keep debris off the roof, out of the valleys, and off the gutter line.

Without maintenance, debris sitting on your composition roof will stay wet. This makes your shingles saturated, and they wont be able to perform their main function, keeping you dry.

If you have a composition roof, its important to have it maintained at least once a year.

What Are The Components Of A Composition Roof

  • Underlayment. Synthetic felt is used on all of our roofing installations. The waterproofing qualities of synthetic underlayment are much better than typical 15 lb. felt.
  • Drip Edge. Drip Edge is a trim piece installed on the perimeter of the roof to allow water to drain and drip off. This prevents water from soaking the fascia wood and causing long-term wood rot.
  • Pro-Start. Pro-Start is installed along the roof perimeter underneath the first shingle. The adhesive on the shingle helps all of the shingles on the edges to stick to the roof. This provides better wind resistance.
  • Ice & Water Shield. Ice & Water shield is like an underlayment on steroids. You can put a nail into it and it will self-heal to prevent leaks. It is used down the valleys and around holes in the roof, such as pipes or vents.
  • Valley Metal. Valley metal is installed down the valleys as a shield to prevent water from leaking in the valley areas.
  • Ridge Caps. There are 3 main types of ridge caps used to accent the roof shingles. Most commonly used are cut-up 25 year shingles. The high-profile ridge caps for GAF are called Z-Ridge and the Class 4 Ridge Caps are UL-2218.
  • Ventilation. Read on to learn about ventilation.

    In high humidity climates and on north-facing roofs asphalt shingles on north-facing roofs asphalt shingles can be prone to algae growth. When excessive moisture collects, it can also lead to issues like mildew growth in the summer and ice dams in the winter. Excessive moisture can even permeate past the roof and into the attic or interior of the home, where it can cause even more damage.

    Polymer composite shingles are naturally better designed for water-shedding and more resistant to moisture, so algae growth, ice dams, and other damaging effects of excessive moisture are off less concern.

    What Are The Downsides To Composition Shingles

  • Algae. One downside to fiberglass shingles is they have a tendency to attract algae, making them not only look dirty, but the formed algae build-up can cause the shingles to lose some of their heat-resisting properties.
  • Granule Loss. Due to the expansion and contraction of the shingles throughout the years, the granules can fall off leaving the exposed fiberglass mat.
  • Blistering. Blistering looks like hail damage, but insurance companies do not cover blistering. Excess heat causes the granules to fall off of the shingles and the exposed fiberglass mat starts to deteriorate.
  • Insurance Endorsements. Insurance companies are adding endorsements to policies, forcing homeowners to pay for their roofs out of pocket. See Actual Cash Value after 15 years of age.
