Roofing tar is a traditional waterproofing material used in various roofing applications, from flat roofs to patching leaks. Buyers typically look for reliability, price, and the right type for their project. This guide explains where to buy roofing tar, what to consider when choosing a product, and practical tips for safe handling and disposal. It covers common sources such as home improvement retailers, roofing supply houses, and online vendors, plus guidance on selecting the appropriate tar for asphalt, coal tar, or modified bitumen applications.
Understanding Roofing Tar And Its Uses
Roofing tar is a viscous, sticky substance designed to seal and waterproof roofing surfaces. It comes in several forms, including hot-applied asphalt tar, coal tar, and modified asphalt products, each suited to different climates and roof types. Tar provides durable resistance against UV exposure, wind-driven rain, and temperature fluctuations. Users should match the tar’s composition to the roof’s material, slope, and expected exposure to ensure long-term performance and safer application.
Where To Buy Roofing Tar
Several reputable sources offer roofing tar, with options for both professionals and DIYers. Home improvement stores like The Home Depot and Lowe’s typically stock common asphalt tar canisters and roofing sealants. Roofing supply houses provide a broader selection, including heavier-duty asphalt tar, coal tar, and cold-applied products, often with regional availability. Online retailers such as major e-commerce platforms and specialized roofing suppliers provide convenience and bulk options. Industrial distributors serve commercial projects requiring larger quantities or specific formulations.
When selecting a seller, verify product specifications, coverage rates, and the tar type. Check customer reviews for long-term performance and confirm that the product meets local building codes or manufacturer recommendations for your roof system. For urgent needs, local stores with same-day pickup can save time, while online orders may offer bulk discounts and shipping to job sites.
Types Of Roofing Tar To Know
Understanding the main types helps buyers choose the right product for their project. Asphalt roofing tar is common for flat roofs and patches, offering good adhesion and water resistance. Coal tar products are more heat resistant and historically used for built-up roofs but may emit stronger fumes and require ventilation. Modified bitumen tar blends with polymers to improve elasticity and durability, suitable for fluctuating temperatures. Each type has distinct handling guidelines and safety considerations.
Choosing The Right Tar For Your Roof
Key considerations include climate, roof material, and project scope. For DIY repairs on a flat asphalt roof, a standard asphalt tar with a brush-on or molten application may suffice. For larger commercial roofs in hot climates, modified bitumen products with polymer modifiers offer better seal integrity. Temperature matters: hot-applied tar requires heating equipment, while cold-applied options reduce hazard. Always review safety data sheets, use appropriate PPE, and maintain proper ventilation during application and curing.
Quality indicators to look for include consistency, tackiness, aging resistance, and curing time. A tar with lower volatile organic compounds (VOCs) and compliant labeling reduces health risks and simplifies disposal. If in doubt, consult a roofing contractor or the tar manufacturer’s guidelines to prevent failed seals or leaks.
How To Compare Prices And Quantities
Pricing varies by tar type, container size, and vendor. Typical options include small cans or pails for repairs and large drums for commercial applications. Per-gallon or per-pound pricing is common, with bulk purchases offering notable savings. Consider total project quantity, not just unit price, to avoid leftovers. Some suppliers offer contractor pricing or seasonal discounts. Always factor shipping or local pickup costs when ordering online, especially for heavy containers.
Buying And Using Safely
Safety is essential when handling roofing tar. Wear protective gloves, long sleeves, eye protection, and, if heating tar, flame-retardant gear and proper ventilation. Keep tar away from open flames and sparks, as fumes can be flammable. Use appropriate tools—brushes, trowels, or squeegees—based on tar viscosity. Store tar in sealed containers in a cool, dry place away from sunlight. Dispose of tar waste according to local hazardous waste guidelines to protect people and the environment.
Environmental And Disposal Considerations
Roofing tar can contain hazardous components, so proper disposal is important. Follow local regulations for disposing of used tar, rags, and contaminated materials. Some municipalities require hazardous waste pickup, while others accept tar-soaked materials at designated facilities. When possible, reuse or recycle compatible products and avoid pouring tar down drains or onto soil. If a roof project generates significant tar waste, coordinate with the waste management program to ensure compliant handling.
Frequently Asked Questions
- Can I buy roofing tar at a hardware store? Yes, most large hardware or home improvement stores carry common asphalt tar products suitable for minor repairs.
- Is coal tar safer than asphalt tar? Coal tar can have stronger fumes and higher odor; asphalt tar is generally easier for DIY use with safer handling if proper ventilation is used.
- Do I need heating equipment for tar? Hot-applied tar requires heating equipment, while cold-applied products are ready to use straight from the container.
- What safety gear is recommended? Gloves, eye protection, long sleeves, and good ventilation are essential; consider respirators for certain products and fumes.
- How do I estimate how much tar I need? Calculate the roof area in square feet, apply the product’s coverage rate per gallon or per drum, and add a contingency for overlaps and waste.
