Signs Your Tar & Gravel Roof Needs Repair

Tar and gravel roofs are a common choice for flat or low-slope roofs, particularly in commercial buildings and some residential properties. These roofs are durable and offer excellent protection against the elements, but like all roofing systems, they require maintenance and repair over time. Understanding the signs that your tar and gravel roof needs repair can help you address issues before they become more significant problems. In this blog, we will explore key indicators that your tar & gravel roof may need attention and provide guidance on how to know if your tar gravel roof needs repairs.

Tar & Gravel Roofs

Before diving into the signs that repairs are needed, it’s important to understand what a tar & gravel roof is and how it functions. Tar and gravel roofing is a type of built-up roofing (BUR) system. It typically consists of multiple layers of asphalt-saturated felt (or other materials) that are bonded together with layers of hot tar. A layer of gravel is then applied on top for additional protection. This combination of materials provides a strong, waterproof barrier that can withstand harsh weather conditions.

Common Problems with Tar & Gravel Roofs

Like any roofing system, tar & gravel roofs can experience a range of issues over time. The most common problems include:

• Cracking and Splitting: The tar on your roof can become brittle over time, leading to cracks and splits that may allow water to penetrate.
• Blisters and Bubbles: These can form when trapped moisture beneath the surface expands and causes the roofing material to lift.
• Pooled Water: Flat roofs are prone to ponding water if they do not have proper drainage. This standing water can lead to leaks and damage.
• Gravel Loss: Over time, the gravel layer may become displaced, reducing the roof’s ability to protect against UV rays and weather.

Signs Your Tar & Gravel Roof Needs Repair

1. Visible Cracks and Splits

One of the most obvious signs that your tar & gravel roof needs repair is the presence of visible cracks and splits in the tar layer. These can be caused by aging, weathering, or physical damage. Cracks and splits can allow water to seep into the underlying layers of your roof, leading to potential leaks and more serious damage.

How to Inspect:

• Look for cracks and splits when performing a visual inspection of your roof.
• Use binoculars if you cannot safely access the roof yourself.
• Check around roof penetrations and seams, as these areas are more susceptible to damage.

2. Blisters and Bubbles

Blisters and bubbles on your tar & gravel roof are usually caused by trapped moisture or poor installation. These issues can weaken the roofing material and lead to further problems if not addressed promptly.

How to Inspect:

• Examine the roof surface for raised areas or bubbles.
• Press gently on the bubbles to see if they feel soft or if moisture escapes.
• Addressing these issues early can prevent more severe damage.

3. Pooled or Ponding Water

Flat and low-slope roofs are prone to pooling or ponding water if the drainage system is not functioning correctly. Standing water can lead to leaks, roof deterioration, and even structural damage over time.

How to Inspect:

• After a rain, check for areas where water remains on the roof.
• Use a hose or bucket to simulate rainfall and observe how water drains from the roof.
• Ensure that gutters, downspouts, and drains are clear and functioning properly.

4. Loss of Gravel

The gravel layer on a tar & gravel roof serves as a protective barrier against UV rays and physical damage. Over time, gravel can become displaced due to wind, foot traffic, or other factors. Loss of gravel can reduce the roof’s effectiveness and increase the risk of damage.

How to Inspect:

• Look for areas where gravel has worn away or is missing.
• Check for exposed tar or asphalt in these areas.
• Consider having a professional inspect the roof for additional issues.

5. Leaks and Water Stains

Leaks are a serious issue that can result from various problems with your tar & gravel roof. Water stains on the ceiling or walls inside your building are often a clear sign that water is getting through the roof.

How to Inspect:

• Look for water stains or discoloration on your ceilings and walls.
• Check the attic or interior spaces for signs of water intrusion.
• If you suspect a leak, it’s important to address it immediately to prevent further damage.

6. Increased Energy Costs

A sudden increase in energy costs can sometimes be linked to problems with your roof. If your tar & gravel roof is not performing effectively, it may not provide adequate insulation, leading to higher heating and cooling costs.

How to Inspect:

• Compare recent energy bills with historical data to identify any significant increases.
• Consider if other factors, such as HVAC system issues, could be contributing to higher energy costs.
• A professional roofing inspection can help determine if roof problems are affecting your energy efficiency.

How to Know If Your Tar Gravel Roof Needs Repairs

Determining whether your tar gravel roof needs repairs involves both visual inspections and professional evaluations. Here are steps you can take to assess the condition of your roof:

1. Perform Regular Visual Inspections

Conduct regular inspections of your tar & gravel roof to identify any visible signs of damage. This should be done at least twice a year, preferably in the spring and fall. Look for the signs mentioned above, including cracks, blisters, and gravel loss.

2. Check for Internal Signs of Damage

Monitor the interior of your building for any signs of water damage, such as stains or leaks. This can help you pinpoint areas of the roof that may be experiencing issues.

3. Hire a Professional Roofing Contractor

While DIY inspections are helpful, it’s essential to hire a professional roofing contractor for a thorough evaluation. A professional can provide a more detailed assessment of the roof’s condition and recommend appropriate repairs.

4. Address Problems Promptly

If you identify any signs of damage or issues with your tar & gravel roof, it’s crucial to address them promptly. Delaying repairs can lead to more severe problems and higher repair costs.

Conclusion

Understanding the signs that your tar & gravel roof needs repair is essential for maintaining the integrity and longevity of your roofing system. By performing regular inspections, monitoring for internal signs of damage, and addressing issues promptly, you can help ensure that your roof continues to provide effective protection for your property.

Remember, when it comes to roof repairs, it’s always a good idea to consult with a professional to ensure that any issues are properly addressed. Taking proactive steps to maintain your tar & gravel roof can save you time, money, and hassle in the long run.
