Commercial roofs, particularly those in humid subtropical climates like Shreveport, face several common issues that can compromise their structural integrity if not addressed. According to industry standards and local expert insights, common problems include:

1. Leaks and Moisture Infiltration: These are frequently caused by failing sealants, especially around flashings and penetrations. Heavy rains and high humidity can accelerate these issues.
2. Ponding Water: On flat or low-slope roofs, debris can block drainage systems, leading to standing water that creates structural strain and membrane degradation.

1. Material-Specific Issues:

• TPO systems may experience seam separation or membrane degradation over time.
• EPDM systems can suffer from punctures or the need for patches due to storm impacts.
• Built-Up Roofing (BUR) often requires monitoring for blisters which indicate moisture trapped between layers.

1. Environmental Damage: High winds (up to 70 mph) and hail events can cause significant surface damage, punctures, and uplift.
2. General Wear and Lack of Maintenance: Issues such as granule loss, moss growth, and corrosion of HVAC units or vents are common when routine bi-annual inspections and cleaning are neglected.
