What are architectural shingles?

Architectural shingles, also called dimensional or laminated shingles, are a type of asphalt roofing. They are made by bonding two or more layers of asphalt. The core of the material is fiberglass, and the top layer contains mineral granules with a ceramic coating. These granules give the product its color and texture, protect it from sunlight, and enhance its fire resistance.

An important function of a roof is to protect the home and its contents from the forces of nature. Architectural shingles achieve an additional goal — they improve the building’s appearance. This is possible thanks to the creation of a three-dimensional effect.

Here are the key features of laminated shingles:

• Multi-layered — the lower layers provide strength and moisture protection, while the top layer focuses on aesthetics.
• Dense structure — a thicker construction makes the material resistant to extreme weather.
• Attractive texture — options are available that mimic wood, slate, and other natural materials.

It is possible to choose architectural shingles to match any facade style. The color palette is close to natural tones. Elements imitating wood or stone are much easier to install and maintain than their natural counterparts.

Notably, the mineral granules on the shingle surface protect against the growth of blue-green algae, slowing the appearance of streaks or color changes.

Dimensional shingles, like any material, have strengths and weaknesses. Advantages include:

• Aesthetic appeal and design versatility — you can select color or texture to match a custom project.
• Durability and longevity compared to other materials — shingles withstand harsh weather and last longer than many other types of roofing.
• Impact resistance and weatherproofing — this type of roof reliably protects the home from strong winds, snow, and hail, minimizing damage to interior finishes and reducing repair costs.

Other factors to consider when choosing a roofing type:

• Asphalt-based roofs are prone to cracking, warping, and chipping after exposure to extreme weather. For homes in hurricane-prone areas, stronger alternatives may be better.
• Architectural shingles are relatively heavy, requiring reinforced roof structures to support their weight.
• Asphalt roofing reduces a building’s energy efficiency, as it quickly absorbs solar heat and transfers it indoors, increasing air conditioning costs.
• Asphalt-based materials are minimally recyclable and decompose slowly. This is important if environmental impact is a concern.
