  • Tar and Gravel Roof Repair: A Complete Guide

    Roofs are an essential part of any building, and they provide protection from the elements. One popular type of roofing system is the tar and gravel roof, also known as a built-up roof. This type of roof consists of layers of tar or asphalt and gravel, which provide excellent durability and water resistance.

    Over time, tar and gravel roofs may develop issues that require repair. In this article, we will explore some common problems with tar and gravel roofs and discuss the steps you can take to repair them effectively.

    1. Ponding Water: One of the most common issues with tar and gravel roofs is ponding water. This occurs when water accumulates on the roof’s surface due to poor drainage. Over time, the pooled water can cause damage to the roof and lead to leaks.

    To repair ponding water issues, it is crucial to improve the roof’s drainage system. This may involve creating additional drains or installing tapered insulation to ensure proper water flow. Additionally, any damaged areas in the roof’s surface should be repaired or replaced.

    2. Cracked or Blistered Surface: Another problem that tar and gravel roofs may encounter is a cracked or blistered surface. This can happen due to extreme temperature fluctuations, heavy foot traffic, or inadequate maintenance.

    To repair a cracked or blistered surface, it is essential to clean the affected area thoroughly. Remove any loose gravel, dirt, or debris. Next, apply a suitable roof patching material to seal the crack or blister. Smooth the patch with a trowel and ensure it adheres properly to the roof’s surface. Finally, top the repaired area with a new layer of gravel to restore its appearance and protect it from further damage.

    3. Leaks: Leaks are a common problem in any type of roof, including tar and gravel roofs. These leaks can occur due to damaged flashing, cracked seams, or deteriorated roofing materials.

    To repair leaks in a tar and gravel roof, it is crucial to locate the source of the leak accurately. This may require a thorough inspection of the roof’s surface. Once the source is identified, clean the area and apply appropriate sealants or patching materials. If the damage is severe, it might be necessary to replace the damaged section of the roof.

    4. Wear and Tear: Over time, tar and gravel roofs will naturally experience wear and tear. This can manifest as loose gravel, worn-out layers of tar, or deteriorated insulation.

    To address general wear and tear, regular maintenance is key. This includes inspecting the roof for any signs of damage, removing debris and loose gravel, and applying a protective coating or additional layers of tar as needed. It is crucial to stay proactive and address any issues promptly to prevent further damage and extend the roof’s lifespan.

    In conclusion, tar and gravel roofs are a popular choice for many buildings due to their durability and water resistance. While they can develop issues over time, proper maintenance and timely repairs can help prolong their lifespan and ensure their effectiveness. If you notice any problems with your tar and gravel roof, it is best to consult with a professional roofing contractor to assess the extent of the damage and recommend the appropriate repair solutions.
