ASPHALT ROOFING

A Practical Choice When It Is Designed and Installed the Right Way

Asphalt roofing is the most widely used roofing material across Massachusetts, Rhode Island, NH and Connecticut. It is chosen for its balance of durability, cost, and appearance, but the material itself is only part of the equation.

How the system is built, how it is ventilated, and how it is installed all play a major role in how long an asphalt roof will actually last.

At Hemlock Roofing, asphalt roofing is treated as a complete system, not just a surface layer of shingles.

Why Asphalt Roofing Is So Common in New England

Homes throughout this region face a wide range of weather conditions throughout the year. Snow accumulation, ice formation, heavy rain, and seasonal temperature changes all place stress on a roofing system.

Asphalt shingles have remained the most common choice because they are adaptable to these conditions when installed correctly. They offer flexibility during temperature changes, provide strong water shedding capabilities, and can be integrated into a full roofing system that protects against moisture intrusion.

However, performance depends heavily on what is happening beneath the shingles and the quality of installation.

Not All Asphalt Roofs Perform the Same

Two homes can have asphalt roofs installed at the same time and experience very different outcomes over the years.

In many cases, the difference comes down to factors that are not visible once the installation is complete.

Ventilation plays a major role. When airflow is not balanced, heat and moisture build up in the attic. This can shorten the life of the shingles and contribute to issues like ice dams in winter.

Water protection is another critical factor. Without proper underlayment and sealing in key areas, water can work its way beneath the shingles during heavy rain or freeze and thaw cycles.

Even small details, such as how flashing is installed around chimneys or where roof sections meet, can determine whether a roof remains watertight over time.

Understanding the Structure Beneath the Shingles

An asphalt roof is made up of multiple layers that work together to protect your home.

The shingles themselves act as the first line of defense, shedding water and protecting against direct exposure to the elements. Beneath them is a layer of roof deck protection, which provides a secondary barrier against moisture.

In areas where water tends to collect or back up, such as along eaves and in valleys, additional protection is installed to prevent infiltration. These areas are especially important in New England, where ice buildup can force water underneath the surface layer.

Ventilation components are integrated into the system to allow air to move through the attic space. This helps regulate temperature and reduce moisture buildup, both of which affect long term performance.

When all of these elements are installed correctly, the system functions as a whole rather than a collection of separate parts.

Choosing the Right Asphalt Shingles for Your Home

Not all asphalt shingles are the same. Differences in design, thickness, and construction affect how they perform and how they look over time.

Architectural shingles are the most common choice for residential homes today. They offer a more dimensional appearance and tend to provide better durability compared to basic three tab shingles.

Color selection also plays a role beyond appearance. Darker colors may absorb more heat, while lighter tones can reflect more sunlight. These factors can influence attic temperature and overall energy performance.

The right choice depends on the structure of your home, your preferences, and how the roof will be exposed to the elements.

How Long Does an Asphalt Roof Last

Many homeowners are told to expect a lifespan of 20 to 30 years from an asphalt roof. While that is possible, actual performance varies based on installation quality and environmental conditions.

In this region, roofs that are properly ventilated and protected tend to last longer and perform more consistently. Roofs that lack proper airflow or were installed without attention to key details often show signs of wear much earlier.

Understanding these variables helps set realistic expectations and ensures that your investment performs as intended.

When It Is Time to Replace an Asphalt Roof

Over time, all roofing materials begin to show signs of aging. With asphalt roofing, this often appears as granule loss, curling or cracking shingles, and recurring leaks.

In some cases, isolated issues can be addressed with targeted repairs. In others, these signs indicate that the system as a whole is reaching the end of its lifespan.

A full evaluation is the best way to determine whether continued repairs make sense or if replacement is the more effective solution that lasts.

FAQs

How long do asphalt shingles really last?

Most asphalt roofs are expected to last around 20 to 30 years, but that range depends heavily on ventilation, installation quality, and weather exposure. In New England, roofs that are properly installed and ventilated tend to last longer, while poorly ventilated systems often show wear much earlier.

What are the main advantages of choosing asphalt shingles over other roofing materials?

Asphalt shingles are among the most popular roofing materials for various reasons. Here are the main advantages of choosing asphalt shingles over other roofing materials:

  • Cost-Effective: Compared to other roofing materials like metal, slate, or tile, asphalt shingles tend to be more affordable both in terms of material cost and installation.
  • Versatility: Asphalt shingles are available in a vast array of colors, styles, and textures. This range ensures that homeowners can find the perfect match to complement their home's aesthetic.
  • Ease of Installation: Asphalt shingles are relatively easy and quick to install, which can mean lower labor costs and a faster project completion time.
  • Durability: While they may not last as long as some other materials, a well-maintained asphalt shingle roof can last between 20 to 30 years. Advances in technology have also introduced more durable and longer-lasting shingle options.
  • Weather Resistance: Many asphalt shingles are designed to withstand adverse weather conditions, including high winds, heavy rains, and even hail. Some are also rated for fire resistance.

Overall, asphalt shingles offer a combination of affordability, durability, and aesthetic appeal, making them a favored choice for many homeowners.

How energy-efficient are asphalt shingles, and can they help reduce my energy bills?

Asphalt shingles vary in their energy efficiency, but advancements in roofing technology have made it possible for them to play a role in reducing energy bills. Here's a breakdown of their energy efficiency and potential cost-saving benefits:

  • Reflective Granules: Some modern asphalt shingles are embedded with specially-designed reflective granules that bounce back a higher percentage of the sun's rays, rather than absorbing them. This can help keep homes cooler during hot months.
  • Cool Roof Technology: These are asphalt shingles designed explicitly with energy efficiency in mind. They reflect more ultraviolet (UV) rays and reduce the amount of heat transferred to the building's interior. A cooler attic space means your air conditioning system may not need to work as hard, leading to potential energy savings.
  • Potential Savings: While the exact savings can vary based on factors like location, climate, insulation, and HVAC systems, a more energy-efficient roof can lead to noticeable reductions in cooling costs, especially in sun-intensive regions.
  • Insulation Benefits: While the shingles themselves offer some level of insulation, the roof system's overall efficiency is enhanced by the underlayment, decking, and insulation used. When all components are optimized, the energy efficiency of the entire home can be significantly improved.
  • Long-Term Durability: Energy-efficient shingles, due to their reflective capabilities, may also have a longer lifespan. By reflecting damaging UV rays, these shingles can experience less wear and tear over time, which can indirectly save money by reducing the frequency of roof replacements.

While traditional asphalt shingles may not have been synonymous with energy efficiency, advancements in materials and design have made them a viable option for homeowners looking to cut down on energy costs. However, it's essential to consider the whole roofing system and other factors like proper ventilation and insulation to maximize energy savings.

What are the signs that asphalt shingles are failing?

Common signs include granules collecting in gutters, shingles that are curling or cracking, dark streaks, and recurring leaks. You may also notice uneven wear across different sections of the roof, which can point to underlying issues.

Can I replace just part of my asphalt roof?

In some cases, yes. If the damage is limited and the rest of the roof is in good condition, a partial replacement may work. However, if issues are showing up in multiple areas or the roof is older, a full replacement is often the more reliable long term solution.

Why do asphalt shingles lose granules?

Granule loss happens over time as the roof ages and is exposed to weather. It can also be accelerated by heavy storms, poor ventilation, or lower quality materials. Excessive granule loss is often a sign that the shingles are nearing the end of their lifespan.

Are architectural shingles worth it?

Architectural shingles are generally more durable and longer lasting than basic three tab shingles. They also provide a more dimensional appearance. For most homeowners, they offer better long term value.

Do asphalt shingles work well in snow and ice?

Yes, when installed as part of a complete roofing system. Proper underlayment, ice and water protection, and ventilation are critical for preventing issues like ice dams and water intrusion during winter.

Will a new asphalt roof lower my energy bills?

It can, especially if ventilation is improved during installation. Better airflow helps regulate attic temperature, which can reduce strain on heating and cooling systems.

How do I know if I need repair or full replacement

If problems are isolated and the roof is relatively new, repairs may be enough. If issues are recurring or the roof is aging, replacement is often the more effective option. A full inspection is the best way to determine the right approach.
