For commercial property owners in Corpus Christi, understanding and addressing roofing issues is crucial to maintaining the integrity and functionality of their buildings. Flat roofs, popular for commercial buildings due to their cost-effectiveness and utility space for HVAC systems, face several common problems that can lead to significant damage and repair costs if not managed correctly. This post highlights the top six flat roof issues, offering information that goes beyond general knowledge and how A.T Pioneer Roofing can assist with solutions tailored to the unique roofing challenges faced in the Corpus Christi area.

Poor Drainage

One of the most prevalent issues with flat roofs is inadequate drainage. Unlike sloped roofs, flat roofs do not naturally facilitate water runoff, which can lead to pooling water. This standing water can degrade the roof material, leading to leaks and structural damage over time. Properly designed drainage systems are essential, especially in Corpus Christi, where sudden heavy rainfalls are common. Innovative solutions like tapered insulation systems can promote better water drainage and prevent accumulation.

Thermal Movement

Thermal movement occurs due to the expansion and contraction of roofing materials as they heat up during the day and cool down at night. Over time, this can cause materials to loosen, particularly around seams and joints, leading to leaks. In the Corpus Christi climate, where temperatures can vary significantly between seasons, using roofing materials that can withstand these changes without deteriorating is important.

Energy Efficiency and Insulation

The roof membrane is the primary waterproofing layer on flat roofs, and it is susceptible to a range of damages, from punctures due to foot traffic during HVAC maintenance to tears from flying debris during storms. Regular inspections and the use of durable, puncture-resistant materials can help mitigate these risks. Additionally, reinforcing areas that receive high traffic with walk pads can extend the life of the membrane.

Flashing and Edge Damage

Flashings are critical for sealing the areas where the roof membrane meets other structures like walls and equipment curbs. Damage to flashings and roof edges, often caused by wind uplift or poor installation, can lead to serious leaks. Given Corpus Christi’s susceptibility to high winds, ensuring that flashings are securely installed and regularly maintained is paramount.

UV Radiation Damage

In Corpus Christi, the intense sun can lead to the deterioration of roof materials, particularly those that are not UV resistant. Over time, UV rays can cause materials to become brittle and crack, leading to leaks. Using UV-resistant roofing materials or coatings can protect roofs from sun damage, significantly extending their service life.

Biological Growth

Flat roofs are prone to the growth of algae, mold, and fungi, especially in humid climates like that of Corpus Christi. This biological growth can not only make the roof look unsightly but can also eat away at roofing materials, causing leaks. Solutions include regular cleaning and the use of materials treated with mold inhibitors to prevent growth.
