Understanding Tar and Gravel Roof Repair: Common Mistakes and Solutions

Introduction to Tar and Gravel Roofs

Tar and gravel roofs, often known as built-up roofs (BUR), have been a staple in commercial and residential roofing for decades. Known for their durability, these roofs consist of alternating layers of asphalt and reinforcing fabrics, topped with a layer of gravel. Despite their resilience, they require maintenance and occasional repairs to prolong their lifespan.

Identifying Common Issues

Ponding Water

One of the most frequent problems faced by tar and gravel roofs is ponding water. This occurs when water collects in low spots and doesn't drain properly. Over time, this can lead to leaks and structural damage.

Blistering and Cracking

Blisters and cracks in the roof surface are often a result of poor installation or extreme temperature fluctuations. These can lead to moisture infiltration and further damage if not addressed promptly.

Steps to Repair a Tar and Gravel Roof

Inspection and Cleaning

Begin by inspecting the entire roof for signs of damage. Clean the surface thoroughly to remove debris, which can obscure problem areas.

Repairing Small Cracks and Blisters

Cut away damaged areas with a utility knife.
Apply roofing cement generously to the area.
Embed a piece of roofing fabric into the cement.
Cover with another layer of roofing cement and smooth it out.

For extensive damage, consider consulting a professional to evaluate whether you need a roof replacement in Texas or elsewhere.

Preventive Measures

Regular Inspections: Conduct bi-annual inspections to catch problems early.
Proper Drainage: Ensure all drainage systems are clear and functioning to prevent water accumulation.
Timely Repairs: Address issues like cracks and blisters immediately to avoid larger repairs down the line.

Considering Costs

Repair costs can vary significantly based on the extent of damage and roof size. For those budgeting for repairs, understanding the flat roof repair cost can be crucial in making informed decisions.

FAQ
