Answers to Common Questions About Roof Shingles

From metal to terra cotta, there are all sorts of different roofing materials out there to choose from. One of the most common roofing materials in the United States is still roof shingles.

Continue reading to learn everything there is to know about these shingles.

What are roof shingles?

Shingles are a roof covering consisting of individual overlapping elements. These pieces are usually flat, rectangle shapes that are laid in courses from the edge of the roof up to the top. Each layer overlaps with the joints below to provide further protection for the roofing deck and your home below.

What are asphalt shingles made of?

Roof shingles can be made of all sorts of different materials, like wood, slate, flagstone or even plastic, but asphalt shingles still dominate the market. Here’s what those shingles are made of:

  • Asphalt: Obviously, asphalt shingles are made in part of asphalt. Asphalt is an oil-refinery product that allows the material to be water resistant while adding hardness to the shingle for longevity.
  • Fiberglass: Asphalt shingles are also reinforced with fiberglass to help extend the shingle’s lifespan while adding a bit of insulation to the material to keep the home or structure more comfortable.
  • Granules: The first thing you’ll notice when you touch an asphalt shingle is how rough it is. Stone is crushed into tiny granules and then applied to the shingle in the manufacturing process. These granules can also be colored to give homes a unique look.
  • Sealant: We use a thermally-activated asphalt sealant to connect the shingles to the roof. The sealant holds the shingles together and to the roof, protecting your home from all sorts of nasty weather.

When is it time for new roof shingles?

Depending on the material they’re made of, shingles can last for decades before they need to be replaced. For example, asphalt shingles can last for 20 years, while wood roof shingles can last for 30. These are a few signs it’s time to replace them:

  • Interior leaks: The first sign that it’s time for a new roof is leaking inside your home. These leaks can indicate that there are gaps between the shingles, allowing water to seep through the surface and down onto the roofing deck below.
  • Damaged flashing: The shingles themselves might be fine, but if any flashing is damaged, your home isn’t fully protected from the elements. Damaged flashing can be repaired if it’s caught soon, but roof replacement might be in your best interest as a precautionary measure.
  • Mold or algae growth: Believe it or not, mold and algae feed off roof shingles. This fungal growth looks unattractive and actually compromises your roof’s integrity. Consider replacing your roof as soon as it starts turning green.
