4 Roofing Materials for Alabama Homes

As we dive into the variety of roofing materials and their effects on your home, it is important that we acknowledge not only the general features and benefits of each roofing material but also their ability to withstand weather and keep that valuable conditioned air sealed in:

1) Asphalt Shingles

Asphalt shingles, with a special focus on architectural variety, stand out as the ideal material for roofing in Alabama, considering the state’s dynamic climate. These architectural shingles are crafted from multiple layers of asphalt and fiberglass, endowing them with exceptional durability and strength. Their defining feature is the multi-dimensional look they lend to your roof, adding an element of elegance to your home.

Architectural asphalt shingles are engineered to tackle the various challenges presented by Alabama’s climate. Their enhanced thickness, a key characteristic of architectural shingles, sets them apart from standard three-tab shingles. This thickness fortifies them to withstand the rigors of the climate, from the scorching heat to the occasional storms. 

Moreover, architectural shingles offer homeowners a wide array of styles and colors to choose from, allowing them to achieve their desired aesthetic for their homes.

This attribute ensures that your roof remains secure and undamaged during adverse weather conditions.
• Thanks to their multiple layers and robust composition, architectural shingles are less vulnerable to damage from heavy rain and hail. This resilience guarantees that your home remains well-shielded, even in the face of severe weather.

Cons:

• It’s worth noting that while architectural shingles are generally resilient, they may not provide the same level of impact resistance as certain metal roofing options. This consideration is particularly relevant in areas frequently affected by hail. However, it’s important to emphasize that the overall durability and cost-effectiveness of architectural shingles often outweigh this drawback, making them a preferred choice for homeowners in Alabama.

2. Metal Roofing

When it comes to choosing the next best roofing material for Alabama, metal roofing stands out with a set of unique and appealing features. 

Typically crafted from steel or aluminum, metal roofs are renowned for their remarkable durability, extended lifespan, and unwavering resistance to the elements. Their sleek, modern appearance adds a touch of contemporary.

Metal roofing is engineered to conquer the challenges posed by Alabama’s climate. The use of steel or aluminum renders these roofs exceptionally sturdy, and capable of withstanding the full spectrum of weather conditions, from the sweltering heat to torrential downpours and robust winds.
