Roofing tar offers a dependable solution for sealing seams, patches, and minor roof repairs. Lowe’s carries several tar-based products suited for flat, low-slope, and small-scale roof projects, as well as asphalt cement for patching shingles and flashing. This guide explains the types of roofing tar available at Lowe’s, how to choose the right product, safety considerations, application steps, and tips to maximize durability. It also covers pricing, availability, and alternatives you might consider within the Lowe’s catalog.
Overview Of Roofing Tar And Its Uses
Roofing tar is a viscous, rubberized or asphalt-based sealant designed to waterproof joints and seams on roofs. It is commonly used for patching cracks, sealing around flashing, and creating temporary or permanent waterproof barriers on flat or low-slope roofs. At Lowe’s, homeowners typically find asphalt roof cement, roofing tar in asphalt or coal tar forms, and specialized mastics. These products are favored for their adhesive properties, weather resistance, and ease of application with brushes, trowels, or caulking guns. Proper use requires surface cleanliness, correct selection for temperature, and adherence to manufacturer instructions.
Key Product Types Available At Lowe’s
Understanding the main categories helps homeowners match the right tar-based product to the job at hand. Lowe’s inventory generally includes:
- Asphalt Roof Cement: A versatile sealant used for shingle repairs, small leaks, and vent flashing. It remains pliable in a range of temperatures and adheres well to asphalt shingles and metal flashing.
- Roofing Tar (Asphalt-Based): Typically a thicker, heavier coating intended for sealing seams on flat or low-slope roofs, as well as around chimneys and antennas. It can be used for larger patches where a stronger waterproof barrier is needed.
- Coal Tar Pitch (where available): A heavier, coal tar-based sealant used for more extreme weather exposure. It is less common in residential aisles and may be limited by local regulations due to odor and emissions.
- Roof Mastic/Sealant: Pre-mixed, trowel-ready products that combine tar or asphalt with rubberizers for improved flexibility and long-term water resistance.
How To Choose The Right Roofing Tar At Lowe’s
Selecting the correct product involves considering roof type, climate, and the repair’s scope. Key decision factors include:
- Roof Type: Flat or low-slope roofs benefit from roofing tar with strong adhesion and weatherproofing, while asphalt roof cement works well for shingle repairs and flashing around vents.
- Temperature Range: Some tar products cure best in warm conditions; choose a product rated for the anticipated temperatures during application and cure time.
- Repair Size: Small patches may be adequately served by asphalt roof cement or mastics, whereas larger seams and patches might require asphalt roofing tar or specialized sealants.
- Cure Time And Drying: Consider dry-to-touch and cure times to plan project timing, especially in wet or humid climates.
- VOC And Odor: Some coal tar-based products have stronger odors and VOC emissions; ensure proper ventilation and check local regulations.
Application Tips For Roofing Tar Products
Proper application improves the durability of the repair and helps prevent future leaks. Follow these best practices when using Lowe’s roofing tar products:
- Prepare The Surface: Clean dust, dirt, and loose material from the repair area. Remove rust from metal flashing and ensure a dry surface.
- Protect Surroundings: Use drop cloths to shield siding, landscaping, and gutters. Wear gloves, eye protection, and a long-sleeve shirt.
- Apply Evenly: Use a putty knife, trowel, or caulking gun to apply a uniform layer. For large seams, work in long, straight strokes to minimize ridges.
- Edge Coverage: Extend tar slightly beyond the patch for a proper seal and to deter moisture intrusion at the edges.
- Temperature Considerations: Do not apply in freezing conditions unless the product is formulated for cold-weather use. Warmer days allow quicker cure and easier workability.
- Cleanup: Clean tools with mineral spirits or according to product instructions. Cap containers tightly to prevent skin hardening and odor buildup.
Safety And Compliance Considerations
Roofing tar products are potent sealants with chemical and environmental considerations. Manufacturers provide safety data on handling, application, and disposal. General guidelines include:

- Personal Protective Equipment: Use gloves, eye protection, and a respirator if recommended by the product label.
- Fire Safety: Tar products are typically flammable when in liquid form; keep away from open flames and heat sources during application and curing.
- Disposal: Do not pour leftover tar down drains. Follow local regulations for disposal or recycling of used containers.

Maintenance And Longevity Of Tar-Based Repairs
Properly installed tar-based repairs can last several years, depending on weather exposure, roof material, and maintenance. Regular inspections following heavy rain, wind, or temperature fluctuations help identify early signs of failure. Reapply or top off tar areas as needed to maintain a watertight seal. For older roofs, consider integrating tar repairs with more durable solutions such as professional waterproof coatings or flashing replacements for a longer lifecycle.
Common Pitfalls To Avoid
- Over-Thermal Application: Excessive heat can degrade the product and reduce its effectiveness.
- Improper Surface Prep: Dirty or damp surfaces reduce adhesion and increase leak risk.
- Incompatible Materials: Mixing tar products with incompatible sealants can cause joint failure.
- Ignoring Local Codes: Some tar-based products may be restricted in certain areas due to VOC regulations.
