The Impact of Weather on Commercial Roofing: How to Prepare and Protect
The weather plays a significant role in the health and longevity of commercial roofs. From scorching summer heat to heavy winter snow, extreme weather conditions can take a toll on your roof, leading to damage, leaks, and costly repairs.
Preparing and protecting your commercial roof from these elements is crucial for maintaining its integrity and ensuring the safety of the building’s occupants.
In this article, we'll take a look at how various weather conditions impact commercial roofs and provide some tips on how to mitigate these effects.
The Impact of Different Weather Conditions
Sun and Heat
Prolonged exposure to the sun can cause significant damage to commercial roofs. UV rays can degrade roofing materials, leading to cracks, blistering, loss of elasticity, and loss of surface thickness. High temperatures can also cause thermal expansion and contraction, which can stress and weaken the roof structure over time.
Rain and Moisture
Heavy rainfall can expose weaknesses in your roofing system. Water can seep into small cracks and seams, leading to leaks and water damage. Prolonged exposure to moisture can also promote the growth of mold and mildew, which can compromise the structural integrity of the roof and pose health risks to occupants.
Wind
Strong winds can lift and displace roofing materials, particularly in areas with inadequate fastening or aging materials. Wind-driven debris can also cause punctures and tears, leaving the roof vulnerable to further damage from rain and other elements.
Snow and Ice
Accumulated snow and ice add significant weight to the roof, potentially causing structural stress or even collapse in extreme cases. Ice dams, formed by the freeze-thaw cycle, can block drainage systems, leading to water buildup and leaks.
Hail
Hailstones can cause immediate and visible damage to roofing materials, such as dents, punctures, and cracks. This damage can reduce the roof’s ability to protect the building from other weather elements.
How to Prepare and Protect Your Commercial Roof
Regular Inspections and Maintenance
One of the most effective ways to protect your roof from weather-related damage is through regular inspections and maintenance. Schedule inspections at least twice a year and after major weather events. Look for signs of wear and tear, such as cracks, blistering, loose or missing materials, and water stains on the ceiling. Addressing minor issues promptly can prevent them from becoming major problems. A regular maintenance contract with a trusted roofer is highly recommended and will ensure that your roof is their priority.
Install High-Quality Roofing Materials
Investing in high-quality, weather-resistant roofing materials can significantly enhance your roof’s durability. When installed correctly, materials like metal, EPDM, and PVC offer excellent resistance to various weather conditions. Additionally, consider using Castagra’s Ecodur Roof Coatings for added protection. Ecodur, made from natural castor oil and gypsum, is highly durable, UV-resistant, and can withstand extreme temperatures. It also has excellent adhesion to most substrates, making it ideal for sealing cracks and preventing leaks. Castagra’s Ecodur1 Cool Roof Coating is highly reflective and is listed by the CRRC (Cool Roof Rating Council), making it the perfect choice for warmer environments. Ecodur1's added fibers also make it super tough, with great impact resistance from hail and other extreme weather.
Ensure Proper Drainage
Proper drainage is essential for preventing water buildup on your roof. Ensure that gutters, downspouts, and drainage systems are clear of debris and functioning correctly. Installing additional drainage solutions, such as scuppers or interior drains, can also help manage heavy rainfall and snowmelt. It is also important to ensure that HVAC condensate lines are properly plumbed and not allowed to drain onto the roof surface. Air conditioning condensate can be more corrosive than normal water and lead to early degradation.
Reinforce Roof Fasteners and Flashings
Loose or damaged fasteners and flashings can leave your roof vulnerable to wind and water damage. Regularly check and reinforce these components to ensure they are secure. High-quality roof coatings, like Ecodur, can also be applied to flashings and seams to enhance their waterproofing capabilities.
Trim Overhanging Trees
Overhanging tree branches can pose a risk to your roof during storms. Wind can cause branches to break and fall onto the roof, while leaves and debris can clog drainage systems. Accumulated tree debris will rot, exposing the roof to chemicals and gases it was not designed to resist. Regularly trim trees near your building to minimize these risks.
Snow and Ice Management
In areas prone to heavy snowfall, it’s essential to manage snow and ice buildup on your roof. Use snow rakes or hire professional snow removal services to prevent excessive weight on the roof. Installing heating cables can also help prevent ice dams by promoting proper drainage.
Windproofing Measures
In regions with high wind activity, take measures to windproof your roof. This includes using wind-resistant materials, ensuring proper installation of roofing components, and reinforcing edges and corners. Installing wind straps or clips can also provide additional protection against wind uplift.
Emergency Preparedness Plan
Having an emergency preparedness plan in place can help you respond quickly to weather-related damage. This plan should include contact information for local roofing professionals, procedures for temporary repairs, and guidelines for documenting damage for insurance claims.
