By extending the life of the existing roof, restoration practices contribute to sustainability and reduce the environmental impact associated with manufacturing new roofing materials. This approach not only benefits the environment but also supports sustainable business practices.

    Safety And Operational Continuity

    Roof restorations are less disruptive than full replacements, allowing businesses to continue operations with minimal interruptions. This is particularly important for maintaining productivity and avoiding downtime. Addressing roof issues promptly through restoration also prevents health hazards like mould growth and structural instability, ensuring a safe environment for building occupants.

    Specific Restoration Benefits By Roof Type

    Different types of roofs benefit from restoration in specific ways. For metal roofs, restoration addresses issues such as seam laps, rusted spots, and penetrations around screw heads, enhancing protection against wind-driven rain.

    Single-ply roofs, including EPDM, TPO, or PVC roofs, benefit from the reinforcement of seams and the repair of tears, cuts, and splits, ensuring durability and leak prevention. Built-up or modified bitumen roofs are restored by handling issues with seams, flashings, and penetrations, preventing leaks and maintaining overall roof integrity.

    Proactive Maintenance Plans

    Developing a proactive maintenance plan is essential for the longevity of commercial roofs. Conducting semi-annual inspections helps in the early detection of potential issues, allowing for timely repairs. Hiring experienced roofing professionals for these inspections and repairs ensures thorough and effective maintenance. Regular cleaning and the application of protective coatings further enhance roof durability and efficiency, making preventative maintenance a crucial aspect of building management.

    How Do You Choose The Right Roofing Material For Commercial Roof Restoration?

    Selecting the appropriate roofing material for commercial roof restoration is a critical decision that can significantly impact your building's longevity, energy efficiency, and overall costs. This comprehensive guide provides insights based on information from Superstorm Restoration, Advantage Construction, and Premier Systems Roofing.

    Factors To Consider

    When choosing roofing materials, consider the type of facility. Different materials are suited for different types of facilities. For instance, a manufacturing facility requires a more robust roofing system compared to a warehouse used solely for storage. Evaluate the current condition of your existing roof, including its type, any noticeable protrusions like HVAC units, vents, or skylights, and any specific features that could affect the installation and maintenance of a new roof.

Built-Up Roofing Systems (BUR) offer extra protection through multiple layers and have a lifespan of 15-20 years. Modified Bitumen (MB) is durable and suitable for various temperatures, with a lifespan of about 20 years.

    Polyvinyl Chloride (PVC) is UV-resistant and long-lasting but more expensive, with a lifespan exceeding 25 years. Ethylene Propylene Diene Monomer (EPDM) is an affordable, easy-to-install option that lasts 25-30 years. Metal roofing is extremely durable and can last over 50 years, making it great for energy efficiency and withstanding extreme weather.

    Spray Foam Roofing is energy-efficient and long-lasting with proper maintenance, potentially lasting over 50 years with regular recoating. Asphalt-based roofing is durable and can last around 50 years with regular maintenance.

    Pros And Cons Of Flat Vs. Sloped Roofs

    Flat roofs are easier and cheaper to install and allow for additional storage space. However, they have poor drainage, are prone to debris collection, and require more maintenance. On the other hand, sloped roofs provide better drainage and less debris buildup. They are, however, hazardous for maintenance due to their incline and can be more expensive because of the difficulty in installation.

    What Are The Common Challenges In Commercial Roof Restoration?

    Addressing Standing Water

    Standing water is a common issue in commercial roofs, often due to structural problems or faulty drainage systems. If not addressed promptly, standing water can lead to significant water damage and leaks. Experienced roofers can quickly identify the causes of water pooling and implement solutions to ensure proper drainage and prevent further damage.

    Membrane Shrinkage Or Expansion

    Roofing materials, especially membranes, can shrink or expand due to extreme temperatures and UV exposure. This can cause cracks in the roofing system joints and flashing to pull away from walls, leading to leaks. Addressing this issue often involves removing affected flashing and replacing damaged areas with more resilient materials like EPDM.

    Scheduling Around Inclement Weather

    Unpredictable weather is a significant obstacle in roof restoration projects. Heavy rain, snow, and extreme heat can disrupt timelines and working conditions. Professional roofing contractors must plan for these contingencies by understanding local weather patterns and incorporating flexibility into their project schedules.

    Poorly Installed Flashing

    Flashing, which seals openings in the roof, is crucial for preventing leaks. Poorly installed flashing can lead to water ingress and subsequent damage. Ensuring proper flashing installation is essential for maintaining the roof's integrity and preventing water-related issues.

    Ponding Water

    Water pooling on the roof, often due to uneven surfaces, clogged gutters, or poor drainage from HVAC units, can cause significant problems. Preventing ponding water involves regular maintenance tasks like cleaning gutters and ensuring proper drainage systems are in place.

    Roof Punctures

    Wind, hail, and heavy foot traffic can cause punctures in the roofing material. Even small punctures can lead to moisture penetration and extensive damage. Regular inspections, especially after severe weather events, can help identify and repair punctures before they cause major issues.


    Blisters in roofing materials, caused by trapped moisture or air, can expand with temperature changes and lead to significant damage. While minor blistering may not require immediate attention, significant blistering should be addressed to prevent costly repairs.

    Lack Of Maintenance

    Many commercial roof issues stem from inadequate maintenance. Regular inspections and proactive maintenance can identify small problems before they escalate into major repairs. A proactive maintenance program extends the roof's lifespan and reduces the likelihood of significant damage.

    Tree Damage

    Overhanging branches can scratch the roof surface, and fallen limbs can cause severe damage during storms. Regularly trimming trees and installing gutter guards can prevent these issues and protect the roof from damage caused by trees.
