Asphalt shingles are a popular choice for roof coverings due to their durability, cost-effectiveness, and aesthetic appeal. However, over time, even the best quality shingles may develop leaks or cracks, requiring some repairs to maintain the integrity of the roof. One common method used to address these issues is applying roofing tar and cement. In this article, we will explore the possibilities and limitations of using roofing tar and cement on asphalt shingles.
Understanding Roofing Tar and Cement
Roofing tar and cement are commonly used materials in roof repair and maintenance. Roofing tar, also known as roof cement, is a thick, sticky substance made of coal tar or asphalt. It is used to seal cracks, gaps, or areas where there is potential for water penetration. Roofing cement, on the other hand, is a mix of asphalt, fillers, and fibers that creates a strong adhesive when combined with roofing tar. This mixture is ideal for bonding roofing materials together.
Advantages of Using Roofing Tar and Cement
When applied correctly, roofing tar and cement can provide several benefits for repairing asphalt shingles:
- Water Resistance: One of the main advantages of using roofing tar and cement is their ability to create a watertight seal. This can help prevent leaks and water damage in areas where the shingles have been damaged or are starting to deteriorate.
- Versatility: Roofing tar and cement can be used on various roofing materials, making them suitable for different types of roofs, including asphalt shingles. This versatility makes them a popular choice for DIY repairs.
- Cost-Effective: Compared to other roofing repair methods, using roofing tar and cement is generally more cost-effective. They are readily available at hardware stores and can be applied without the need for professional assistance, saving both time and money.
Applying Roofing Tar and Cement to Asphalt Shingles
Before applying roofing tar and cement to asphalt shingles, it is essential to determine the extent of the damage. Minor cracks or gaps can typically be repaired using roofing tar alone, while more significant damage may require a combination of tar and cement.
Step-by-Step Application Process:
- Prepare the Surface: Clean the area around the damaged shingles by removing any debris or loose particles. A wire brush or scraper can be used to ensure the surface is clean and smooth.
- Apply Roofing Tar: Using a trowel or putty knife, spread a thin layer of roofing tar over the damaged area, extending slightly beyond the affected shingle. Ensure the tar is evenly applied, covering any cracks or gaps.
- Add Roofing Cement: For more substantial repairs, mix roofing cement with the tar according to the manufacturer’s instructions. Apply the cement mixture over the tarred area, pressing it firmly to create a strong bond.
- Smooth and Seal: Smooth the surface of the repaired area to create an even finish using a trowel. Finally, apply a thin layer of roofing tar over the entire repaired section to seal it and provide additional waterproofing.
Limitations and Considerations
While roofing tar and cement can be useful for smaller repairs on asphalt shingles, there are some limitations to keep in mind:
- Temporary Solution: Roofing tar and cement repairs are considered temporary and may need to be re-applied or replaced after a certain period. This is because the materials can degrade over time due to exposure to elements like sunlight and weather conditions.
- Appearance: The repairs made with roofing tar and cement may not match the color or texture of the surrounding shingles, affecting the overall aesthetic appeal of the roof.
- Professional Assistance: More extensive damage or complex repairs may require professional expertise. If you are unsure about the extent of the damage or lack experience in repairing roofs, it is advisable to consult a roofing professional.
Using roofing tar and cement can be a viable option for repairing minor damages on asphalt shingles. They offer water resistance, versatility, and a cost-effective solution for DIY repairs. However, it is essential to evaluate the extent of the damage and consider the limitations associated with tar and cement repairs. For more extensive or complex issues, it is recommended to seek professional assistance to ensure a long-lasting and aesthetically pleasing solution to protect your roof.
