Replacing an old Built-Up Roof (BUR) is a crucial maintenance task to ensure the safety and longevity of your building. This step-by-step guide will walk you through the process, helping you understand each phase from preparation to completion.
Preparation and Safety Measures
Before starting the removal process, gather all necessary tools and materials, including roofing knives, pry bars, new roofing materials, and safety gear such as gloves, goggles, and harnesses. Ensure the work area is clear of debris and that you have proper ventilation. Safety is paramount when working on roofs.
Inspect the Existing Roof
Begin by inspecting the old BUR roof for signs of damage, such as cracks, blisters, or leaks. Check the underlying deck for rot or deterioration. This assessment helps determine the extent of removal and any repairs needed before installing the new roof.
Remove the Old Roofing Material
Carefully strip away the old BUR layers using roofing knives and pry bars. Remove all debris, including gravel, tar, and felt. Be cautious to avoid damaging the underlying deck. Proper disposal of old roofing material is essential for safety and environmental reasons.
Repair and Prepare the Deck
Once the old roof is removed, inspect the deck for damage. Repair any rotten or weakened sections with suitable materials. Clean the surface thoroughly to ensure a smooth and secure base for the new roofing layers.
Install a New Base Layer
Apply a primer or base sheet as recommended by the roofing manufacturer. This layer provides a waterproof barrier and enhances adhesion for the subsequent layers. Follow the manufacturer’s instructions for proper installation.
Apply the New BUR Layers
Build up the new roof with multiple layers of hot asphalt and roofing felt, ensuring each layer is properly sealed and overlapped. Finish with a gravel or reflective coating if desired. Proper application ensures durability and weather resistance.
Final Inspection and Maintenance
After installation, inspect the entire roof for any missed spots or imperfections. Check for proper drainage and secure all flashing. Regular maintenance, including cleaning and inspections, will extend the lifespan of your new BUR roof.
