Tar Roof Shingle Composition
Tar roof shingles, a common roofing material, are composed of several key elements working together to provide weather protection and aesthetic appeal. Understanding these components and their variations is crucial for selecting the right shingle for a specific climate and building application. The performance and longevity of a roof are directly tied to the quality and interaction of these materials.
Tar roof shingles – The fundamental structure typically includes a base material, asphalt, and protective coatings. The base material provides structural integrity and dimensional stability. Common base materials include fiberglass mats, which offer flexibility and durability, and organic felt, a cellulose-based material that has been traditionally used but is less common now due to its susceptibility to moisture damage. Asphalt, a petroleum-based binder, holds the shingle together and provides waterproofing. This is then typically covered with mineral granules, often made from slate, ceramic, or recycled materials, which protect the asphalt from ultraviolet (UV) radiation and weathering. These granules also contribute to the shingle’s color and texture.
Asphalt Variations and Their Impact on Performance
Different types of asphalt are used in shingle manufacturing, each influencing the shingle’s performance characteristics. The asphalt’s properties, such as its viscosity, flexibility, and resistance to degradation, directly affect the shingle’s lifespan, durability, and resistance to cracking, curling, and granule loss. For instance, modified asphalt shingles utilize polymers or other additives to enhance their flexibility and durability, leading to a longer lifespan compared to those made with standard asphalt. The choice of asphalt is a critical factor influencing the shingle’s overall performance and suitability for different climates and applications. Modified asphalt shingles, for example, often exhibit superior resistance to temperature extremes, making them a good choice for regions with significant seasonal variations.
Base Material Comparison: Fiberglass vs. Organic Felt
The choice between fiberglass and organic felt as the base material significantly impacts shingle properties. Fiberglass mats are known for their dimensional stability, resistance to moisture damage, and overall durability. They are less prone to sagging or curling over time, resulting in a longer-lasting roof. In contrast, organic felt, while historically used, is more susceptible to moisture absorption, which can lead to premature deterioration and reduced lifespan. This susceptibility makes fiberglass a more popular and reliable choice in modern shingle manufacturing, particularly in regions with high humidity or rainfall. The difference in lifespan can be considerable, with fiberglass shingles often outperforming organic felt shingles by several years.
Protective Coatings and Granule Composition
The protective coatings and granule composition play a vital role in shingle performance and longevity. The mineral granules not only provide UV protection but also contribute to the shingle’s fire resistance and aesthetic appeal. The type and size of the granules, along with the composition of the protective coating applied over the asphalt, impact the shingle’s color stability, wind resistance, and overall appearance. High-quality coatings and carefully selected granules can enhance the shingle’s resistance to fading, granule loss, and algae growth, resulting in a more attractive and durable roof that maintains its appearance for an extended period. Different manufacturers may use proprietary coating technologies to further enhance performance characteristics.
Manufacturing Process
The production of tar roof shingles is a multi-stage process involving the careful blending of raw materials, precise manufacturing techniques, and quality control measures to ensure a durable and weather-resistant final product. This process, while seemingly straightforward, requires significant energy input and generates some environmental impact, which is increasingly being addressed by manufacturers through innovation and improved practices.
The manufacturing process begins with the acquisition of raw materials, primarily asphalt, fiberglass mat, and mineral granules. These components are then processed and combined in a carefully controlled environment to create the final shingle. The specific steps involved, along with their associated energy consumption and environmental impact, are detailed below.
Raw Material Acquisition and Preparation
Asphalt, the primary component, is typically sourced from petroleum refineries. Fiberglass mats are produced separately, often using recycled glass. Mineral granules, such as slate, are mined and processed to the desired size and shape.

This stage involves energy consumption primarily for transportation and initial processing of raw materials. Environmental impacts include greenhouse gas emissions from transportation and potential impacts from mining activities, depending on the source of the mineral granules.
Shingle Formation
The prepared asphalt is heated and mixed with additives to modify its properties, such as increasing its flexibility and durability. This mixture is then applied to the fiberglass mat, creating a saturated base layer. This process requires significant energy input for heating and mixing. The environmental impact is primarily related to the energy source used for heating and the potential emissions of volatile organic compounds (VOCs) during the mixing process. Modern manufacturing plants employ advanced emission control technologies to minimize these impacts.
Granule Application and Cooling
After the asphalt-saturated mat has been formed, mineral granules are applied to the surface. This provides protection against ultraviolet (UV) radiation and weathering. The granules are typically applied using a specialized machine that ensures even distribution and adhesion. This step consumes energy primarily for the operation of the application machinery and for the cooling process, which is necessary to solidify the asphalt and ensure the granules adhere properly. Environmental impacts are minimal at this stage, primarily related to the energy consumption of the machinery.
Cutting and Packaging
Once the granules are applied and the shingles have cooled, they are cut into the desired size and shape using high-speed cutting machines. Finally, they are inspected for quality and packaged for distribution. This final stage involves energy consumption primarily from the operation of cutting and packaging machinery. The environmental impact is relatively low, but packaging material use contributes to waste generation. However, many manufacturers are actively working to reduce packaging material usage and promote recycling.
Energy Consumption and Environmental Impact Summary
The overall energy consumption in tar roof shingle manufacturing is significant, primarily due to the heating and mixing of asphalt. The environmental impact includes greenhouse gas emissions from energy use, potential VOC emissions during mixing, and impacts related to raw material extraction and transportation. However, ongoing advancements in manufacturing technology, including the use of more efficient heating systems and emission control technologies, are leading to a reduction in the overall environmental footprint. Specific data on energy consumption and emissions vary significantly depending on the size and efficiency of the manufacturing facility, the energy sources used, and the specific materials employed.

The use of appropriate underlayment and flashing materials is paramount in preventing water intrusion. Paying close attention to detail throughout the installation process will significantly enhance the roof’s lifespan and performance.
Underlayment Installation
Underlayment acts as a secondary barrier against water penetration, providing additional protection should the shingles fail. It is typically a waterproof membrane, often made of asphalt-saturated felt. Proper underlayment installation is essential for a durable and leak-free roof. The underlayment should be laid out smoothly and securely, overlapping each sheet according to the manufacturer’s instructions to ensure complete coverage. Any wrinkles or gaps should be carefully addressed to prevent water from seeping underneath. The underlayment should extend beyond the edges of the roof to create a drip edge.
Flashing Installation
Flashing is crucial for preventing water from entering the roof at vulnerable points, such as around chimneys, vents, and valleys. It consists of sheets of metal or other waterproof material that are installed to create a watertight seal. Proper flashing installation involves carefully shaping and sealing the flashing around the protrusions, ensuring complete coverage and a secure connection to the surrounding roofing materials. The flashing should be installed before the shingles to allow for proper overlap and integration. Common flashing types include step flashing (installed in layers around vertical protrusions), counter flashing (installed over step flashing), and valley flashing (installed in valleys to direct water flow).
Step-by-Step Shingle Installation
A successful tar shingle roof installation follows a structured process.
- Preparation: Begin by ensuring the roof deck is clean, dry, and free of debris. Any damaged wood should be repaired or replaced.
- Underlayment Installation: Lay the underlayment according to manufacturer instructions, overlapping sheets by several inches. Secure the underlayment with roofing staples or nails.
- Starter Course: Install a starter course of shingles along the eaves. This provides a straight, even base for the remaining shingles. This course is often cut to a shorter length than the standard shingles.
- Shingle Application: Begin installing the shingles, starting from the bottom of the roof and working your way up. Each shingle should overlap the previous course by the manufacturer’s specified amount. Use roofing nails to secure each shingle. Align the shingles carefully to ensure even spacing and proper overlap.
- Ridge Installation: Install ridge caps to finish the roof. These are specially designed shingles that cover the ridge of the roof, protecting it from the elements.
- Inspection: Conduct a thorough inspection of the entire roof to check for any gaps, loose shingles, or other defects. Address any issues immediately.
Imagine a roofer carefully laying out a sheet of underlayment, smoothing out any wrinkles, and securing it with roofing staples. Next, they meticulously place the starter course, creating a perfect foundation for the rest of the shingles. Each shingle is then carefully nailed into place, ensuring proper overlap and a neat, uniform appearance. Finally, ridge caps are applied, completing the watertight seal.
