What is Hot Tar Roofing?
Hot tar roofing is a multi-layered roofing system made from asphalt and felt, frequently topped with gravel. This method involves heating tar to a liquid state and applying it to layers of roofing felt, which creates a durable and waterproof barrier. As mentioned in articles from sources like www.taylormaderoofingllc.com and nombach.com, this roofing type is particularly suitable for flat or low-slope roofs, making it a staple in commercial applications.
Pros of Hot Tar Roofing
Durability
One of the most significant advantages of hot tar roofing is its durability. The multiple layers of asphalt and felt provide robust protection against harsh weather conditions, including heavy rainfall and strong winds. With proper maintenance, hot tar roofs can last between 20 to 30 years, as noted by sources like www.freeroofquote.com.
Cost-Effectiveness
Hot tar roofing is often one of the more affordable options for flat roofing. Its materials are widely available, which reduces costs. Installing a hot tar roof is generally less expensive compared to other roofing systems like metal or high-end membranes, making it an attractive option for budget-conscious building owners.
Easy Repairs
As highlighted by springerroofing.com, hot tar roofs are relatively easy to repair. Instead of undertaking a complete roof replacement, minor issues can often be addressed with simple patching techniques. This not only saves money but also extends the life of the roof.
Cons of Hot Tar Roofing
Installation Complexity
While the installation of hot tar roofing can be less expensive, it is not without its challenges. The process is labor-intensive and requires skilled professionals to ensure that the layers are applied correctly. Inadequate installation can lead to leaks and other problems over time.
Strong Odors
During installation, hot tar can emit strong odors, which may be unpleasant for building occupants. This is discussed in articles from www.newimageroofingatlanta.com and roofonline.com. Adequate ventilation and timing the installation during off-hours can mitigate these issues.
Vulnerability to Punctures
Hot tar roofing is susceptible to punctures and damage from foot traffic or falling debris. Although it’s durable, building owners should be cautious about heavy equipment or frequent access to the roof to prevent damage.
Applications of Hot Tar Roofing
Commercial Buildings
Hot tar roofing is commonly used in commercial buildings due to its cost-effectiveness and durability. Many businesses choose this roofing type to protect their assets against the elements while keeping maintenance costs low.
Industrial Facilities
Industrial facilities often benefit from hot tar roofing due to its ability to withstand harsh conditions. The multilayer system provides excellent insulation, which is crucial for factories and warehouses.
Residential Properties
Though less common in residential applications, hot tar roofing can still be found in some flat-roofed homes. It’s particularly useful for homes with rooftop decks or patios, where a durable waterproof barrier is essential.
Installation Process of Hot Tar Roofing
Preparation
Before installation, the roof deck must be thoroughly cleaned to remove debris and contaminants. This ensures proper adhesion of the roofing layers.
Layering
The installation involves laying down multiple layers of roofing felt, each coated with hot tar. This process is repeated until the desired thickness is achieved. The final layer is usually sealed with gravel, which serves as a protective barrier against UV rays.
Finishing Touches
Once the layers are in place, any additional details, such as flashing around vents and chimneys, are added to ensure a watertight seal. Proper finishing touches are critical to the longevity of the roof.
Maintenance of Hot Tar Roofing
Regular Inspections
To prolong the lifespan of a hot tar roof, regular inspections are essential. Building owners should check for any signs of wear, tear, or punctures, especially after severe weather.
Cleaning
Keeping the roof clean is crucial. Debris, leaves, and dirt can hold moisture, leading to potential damage. Regular cleaning helps prevent moss and algae growth, which can degrade the roofing materials.
Professional Care
While simple repairs can often be handled by building maintenance staff, complex issues should be addressed by professionals. Hiring experienced roofers ensures that any repairs or maintenance are done correctly, preserving the integrity of the roof.
