Hailstorms pose a significant threat to commercial roofing systems, often resulting in extensive damage that compromises the integrity of the roof. From punctured membranes to cracked shingles, the effects of hail can be devastating, leading to leaks, water intrusion, and structural issues. Let’s explore the impact of hail damage on commercial roofing and delve into the process of assessing and repairing roof system integrity to ensure the longevity and performance of the roof.
Understanding Hail Damage
When hailstorms strike, the resulting damage to commercial roofing systems can vary significantly based on factors such as the size and density of the hailstones, as well as the type of roofing material in place. Hailstones come in a range of sizes, from small pellets to large chunks of ice, and their impact can cause various types of damage:
- Punctures: Hailstones can puncture the membrane of single-ply roofing systems, such as TPO or EPDM, creating openings that allow water to infiltrate the roofing assembly. These punctures can lead to leaks and water damage within the building.
- Cracks: Asphalt shingles and built-up roofing (BUR) systems may develop cracks or fractures when struck by hail. These cracks compromise the integrity of the roofing materials, making them more susceptible to water penetration and accelerated deterioration over time.
- Granule Loss: Hail impact can knock granules off the surface of asphalt shingles, exposing the underlying substrate to UV radiation and weathering. Granule loss compromises the protective function of the shingles and can accelerate their degradation.
- Denting: Metal roofing panels are particularly vulnerable to denting when struck by hailstones. These dents not only detract from the appearance of the roof but also weaken the structural integrity of the panels, potentially leading to leaks and other issues.
Understanding the specific types of hail damage that can occur is essential for accurately assessing the condition of a commercial roofing system after a hailstorm. By identifying and addressing these issues promptly, property owners can mitigate the risk of further damage and ensure the long-term performance of their roofing systems.
Assessing Hail Damage
After a hailstorm, it is essential to conduct a thorough inspection of the commercial roofing system to assess the extent of the damage. This inspection should include the following.
Visual Examination
During the visual examination, roofing contractors meticulously inspect the entire surface of the commercial roofing system for any visible signs of damage caused by hail. This includes looking for punctures, cracks, dents, or granule loss on roofing materials such as asphalt shingles, single-ply membranes, metal panels, or built-up roofing systems. Contractors pay close attention to vulnerable areas such as seams, flashing, edges, and penetrations, where damage is more likely to occur. They may use binoculars or drones to access hard-to-reach areas and ensure a comprehensive assessment.
Moisture Detection
After a hailstorm, one of the primary concerns is water intrusion, which can lead to further damage and compromise the integrity of the roofing system. To detect areas of trapped moisture, roofing contractors utilize specialized tools and equipment such as infrared thermography cameras, which detect temperature differentials on the roof surface, indicating areas of trapped moisture beneath the roofing materials. These moisture detection methods allow contractors to pinpoint areas of concern accurately and prioritize repair efforts to prevent water damage.
Core Sampling
In cases where the extent of hail damage is uncertain or hidden beneath the surface of the roofing materials, core sampling provides a more thorough assessment of the condition of the roof. During core sampling, contractors extract core samples from various locations across the roof using specialized tools. These samples are typically taken from areas suspected of damage or where moisture intrusion has been detected. Once extracted, the core samples are carefully examined and analyzed to evaluate the depth and severity of hail-related damage, including membrane punctures, substrate degradation, or structural compromise. Core sampling provides valuable insights into the overall condition of the roofing system and informs repair or replacement decisions.
Repairing Roof System Integrity
Once the extent of hail damage has been determined, prompt repairs are necessary to restore the integrity of the commercial roofing system. Repair strategies may include:
- Patching: For minor punctures or tears in the roofing membrane, patching with compatible materials can effectively seal the damaged area and prevent water intrusion.
- Sealant Application: Cracks or gaps in roofing materials can be sealed with specialized sealants to prevent moisture penetration and further deterioration.
- Replacement: In cases of severe damage, such as extensive granule loss or structural compromise, partial or complete replacement of roofing materials may be necessary to ensure the long-term integrity of the roof.
- Protective Coatings: Applying protective coatings, such as elastomeric coatings or UV-resistant sealants, can help mitigate the effects of hail damage and extend the lifespan of the roofing system.
