What Are the Layers of an Asphalt Shingle Roof?

When looking at your home's exterior, it may seem like the roof is a simple layering of asphalt. However, that's far from the truth. Your roof is a complex system that's made up of multiple layers of materials. These layers are important in helping the roof withstand the forces of nature and control the temperature and humidity levels inside. Here are the layers that will be installed when you call a roofing service for your asphalt shingle roof.

Insulation

The insulation layer of your roof is a barrier installed by a roofing service between the rafters. According to Roofing Calculator, residential roofs have an average size of 1,700 square feet, and the insulation layer covers this whole area. It slows down the movement of heat between your living space and the outdoor world. This creates a warmer home in winter and a cooler home in summer. The insulation later improves your home's energy efficiency.

Roof Deck

The roof deck is also known as sheathing and is a layer that's installed over the framing. The deck is the base on which all other components are laid. It's made using plywood or OSB sheets but can also be made using corrugated metal, polystyrene, and reinforced concrete.

Underlayment

This protective layer is installed onto the roof deck to stop leakage caused by ice dams. The most common material used to make the underlayment is felt. This is a durable cloth material that's saturated with asphalt.

Ice and Water Shield

This shield is a waterproof membrane that features a polymer-modified bitumen adhesive on the back. It has a sticky surface that enables it to adhere to the roof deck, creating a watertight seal around the holes created by nails. As you might imagine, it also stops ice and water from penetrating the roof.

Shingles

This is the final layer of an asphalt roof. It's an important part that contributes to the aesthetics and practicality of the roof. Shingles are the first barrier against outside forces like wind, rain, snow, and hail.

These are some of the layers that will come with your asphalt roof installation. With the right team of professionals, you can trust that your roof will last for years to come.

2 Roofing Materials to Consider for Your New Roof Installation Project

01 Jul, 2024

When it comes to your new roof installation project, choosing the right roofing material is crucial. Among the many options available, asphalt shingles and metal roofing stand out as popular and reliable choices. Asphalt Shingles Asphalt shingles are the most common roofing material used in residential projects across the United States. Their popularity stems from several key advantages. Cost-Effectiveness Asphalt shingles are less expensive to purchase and install compared to many other roofing materials, making them an attractive option for budget-conscious homeowners. Ease of Installation The installation process for asphalt shingles is relatively straightforward, which can save time and labor costs. This simplicity also means that repairs and replacements are generally easier and less costly. Variety of Styles and Colors Asphalt shingles come in a wide range of styles, colors, and textures, allowing homeowners to achieve their desired look. Whether you prefer a traditional or modern appearance, there's likely an asphalt shingle that will meet your aesthetic preferences. Durability While not as long-lasting as some other materials, asphalt shingles can still provide good durability, typically lasting 20 to 30 years with proper maintenance from what we have seen. They are also designed to withstand various weather conditions, including moderate winds and impacts. Metal Roofing Metal roofing has gained popularity in recent years due to its durability and modern aesthetic appeal. It offers several significant benefits for a new roof installation. Longevity One of the most compelling advantages of metal roofing is its exceptional lifespan. According to State Farm, if installed correctly, some metal roofs can sustain wind gusts up to 140 miles per hour, will not corrode or crack, and may be impact-resistant. This longevity can offset the higher initial cost, providing long-term value for homeowners. Energy Efficiency Metal roofs are highly reflective, which helps to reduce heat absorption. This energy efficiency can lead to lower cooling costs in warmer climates, making metal roofing an eco-friendly choice for your new roof installation. Low Maintenance Metal roofing requires minimal maintenance compared to other materials. It is resistant to common issues such as rot, mildew, and insect damage, which can save homeowners time and money on repairs and upkeep. Weather Resistance Metal roofs are designed to withstand extreme weather conditions, including high winds, heavy snowfall, and hail. They are also fire-resistant, providing an added layer of safety for your home. Aesthetic Versatility Modern metal roofing comes in various styles and colors, including options that mimic the look of traditional materials like wood, slate, and tile. This versatility allows homeowners to achieve a high-end look while enjoying the benefits of metal roofing. Asphalt shingles provide an affordable, versatile, and easy-to-install option, while metal roofing offers unmatched durability, energy efficiency, and low maintenance.
