Shingle Roofing FAQs

What are the pros and cons of asphalt shingles?

Pros of Asphalt Shingles:

• Affordability: Asphalt shingles are generally the most cost-effective roofing material.
• Versatility: They are available in a wide array of colors, styles, and textures to complement various architectural designs.
• Ease of Installation: Asphalt shingles are relatively easy to install, which can help reduce labor costs.
• Lightweight: They are lightweight and don't put excessive strain on the roof structure.
• Fire Resistance: Most asphalt shingles have a Class A fire rating, providing good protection against fire spread.

Cons of Asphalt Shingles:

• Shorter Lifespan: Compared to some other roofing materials, like metal or tile, asphalt shingles have a relatively shorter lifespan.
• Susceptibility to Weather Damage: They can be susceptible to damage from high winds, hail, and extreme temperature fluctuations.
• Maintenance: Regular maintenance, such as cleaning gutters and removing debris, is required to prevent algae growth and extend their lifespan.

What are the different types of shingle roofs?

The most common types of shingle roofs are asphalt shingles, which are available in two main categories:

• Architectural shingles (dimensional shingles): These have a thicker, multi-layered construction for a more dimensional and aesthetically pleasing look. They are more durable and often come with longer warranties than three-tab shingles.
• Three-tab shingles: These are the traditional type of asphalt shingle with a flat appearance and three tabs per strip. They are more affordable than architectural shingles, but they generally have a shorter lifespan.

Other less common shingle types include wood shingles, slate shingles, and tile shingles, each with their own unique characteristics and price points.

What is the difference between a shingle roof overlay and a roof tear-off?

When replacing a shingle roof, you have two main options: an overlay or a tear-off.

• Shingle Roof Overlay: This involves installing new shingles over the existing layer of shingles. It's a less expensive and quicker option, but it can only be done once and may hide existing problems with the roof deck.
• Roof Tear-Off: A tear-off involves removing the existing shingles and installing new shingles on a clean roof deck. This is more labor-intensive and expensive, but it allows for a thorough inspection and repair of the roof deck, ensuring a solid foundation for the new shingles.

Your roofing contractor can advise you on the best option based on your roof's condition, budget, and local building codes.

How can I make my shingle roof more energy-efficient?

Several steps can make your shingle roof more energy-efficient:

• Choose reflective shingles: Opt for light-colored or 'cool roof' shingles that reflect sunlight and heat, reducing the amount of heat absorbed into your home.
• Adequate attic insulation: Ensure your attic is well-insulated to prevent heat transfer from the roof into your living space.
• Proper ventilation: Proper attic ventilation allows hot air to escape, keeping the roof cooler and preventing excessive heat build-up.
• Radiant barriers: Consider installing a radiant barrier in your attic to reflect radiant heat away from your home.

These measures can help lower your energy bills and create a more comfortable indoor environment.
