Roof hatches are essential access points on commercial buildings, providing entry to rooftop equipment, maintenance personnel, and emergency escape routes. However, improper flashing installation can lead to water intrusion, compromising the integrity of the roof and the structure below. In this comprehensive guide, we'll delve into the intricacies of flashing a roof hatch on a built-up roof using the hot application method, ensuring a watertight seal and long-lasting protection for your property.
Flashing serves as the first line of defense against water infiltration around roof penetrations such as hatches. On built-up roofs (BUR), which consist of multiple layers of bitumen and reinforcement fabrics, ensuring a secure flashing installation is crucial for preventing leaks and preserving the roof's lifespan. Hot application flashing, which involves melting bitumen to create a waterproof seal, is a preferred method for its durability and effectiveness.
Before beginning the flashing process, it's essential to prepare the work area and adhere to all life safety rules and regulations as outlined by International Building Codes and OSHA. This includes ensuring proper ventilation to dissipate fumes from heating bitumen, wearing appropriate personal protective equipment (PPE), and securing the hatch opening to prevent accidents or falls.
Flashing a roof hatch on a built-up roof using the hot application method requires precision, attention to detail, and adherence to safety protocols. By following the steps outlined in this guide and employing best practices, you can effectively protect your commercial property from water intrusion and extend the life of your roof. Remember, investing in proper flashing installation today can save you from costly repairs and downtime in the future.
