Tar and gravel roofing, also known as built-up roofing (BUR), has been a popular choice for commercial and residential buildings for decades due to its durability and longevity. However, like any roofing system, tar and gravel roofs require maintenance and eventual replacement to ensure continued protection for your property. In this guide, we’ll walk you through everything you need to know about tar and gravel roof replacement.
Understanding Tar and Gravel Roofing:
Tar and gravel roofing consists of multiple layers of bitumen-saturated roofing felt or fiberglass mats alternated with layers of hot-applied asphalt and topped with a layer of gravel or aggregate. This multi-layered construction provides excellent waterproofing and protection against the elements, making tar and gravel roofs a durable and reliable choice for flat or low-slope roofs.
Signs it’s Time for Replacement:
Over time, tar and gravel roofs can deteriorate due to exposure to UV radiation, temperature fluctuations, and moisture. Signs that your tar and gravel roof may need replacement include:
- Blisters or Bubbling: Blisters or bubbling in the roof membrane can indicate trapped moisture and potential delamination of the roofing layers.
- Cracking or Splitting: Cracks or splits in the roof membrane can compromise its waterproofing ability and lead to leaks.
- Excessive Wear: Wear and tear, including granule loss and aggregate displacement, can weaken the roof surface and reduce its lifespan.
- Water Damage: Water stains on ceilings or walls, as well as signs of moisture in the attic, suggest that the roof is no longer effectively protecting the building from leaks.
- Sagging or Ponding: Sagging or ponding water on the roof surface indicates structural issues and poor drainage, which can lead to further damage over time.
The Replacement Process:
Tar and gravel roof replacement typically involves the following steps:
- Roof Inspection: A thorough inspection is conducted to assess the condition of the existing roof and identify any underlying issues that need to be addressed.
- Tear-Off: The existing roofing materials, including the layers of tar, gravel, and membrane, are removed to expose the underlying roof deck.
- Deck Repair: Any damaged or deteriorated sections of the roof deck are repaired or replaced to ensure a solid substrate for the new roofing system.
- Installation of New Roofing System: The new roofing system, which may consist of modern materials such as single-ply membranes or modified bitumen, is installed according to manufacturer specifications.
- Final Inspection: Once the replacement is complete, a final inspection is conducted to ensure that the new roof meets quality standards and provides effective waterproofing protection.
Benefits of Tar and Gravel Roof Replacement:
- Enhanced Durability: Modern roofing materials offer improved durability and resistance to weathering, extending the lifespan of the roof.
- Improved Energy Efficiency: Upgrading to a more energy-efficient roofing system can help reduce heating and cooling costs and improve indoor comfort.
- Reduced Maintenance: New roofing systems require less maintenance than traditional tar and gravel roofs, saving time and money on upkeep.
- Enhanced Aesthetics: A new roof can enhance the appearance of your property and increase its curb appeal, contributing to its overall value.
