Flat roofs are a popular choice for commercial and industrial buildings due to their cost-effectiveness and ease of installation. However, they require regular maintenance and inspections to ensure their longevity and prevent potential issues. Flat roof surveys are an essential part of this maintenance, providing property owners with a comprehensive report of the roof’s condition, including any necessary repairs or replacement. In this blog post, we will discuss the importance of flat roof surveys and the most common issues found on felt roofs, asphalt roofs, and single-ply roofs.
Why Flat Roof Surveys are Important
Flat roof surveys provide a detailed report of the roof’s condition, identifying any potential issues before they become major problems. This can save property owners significant amounts of money in repairs and replacements, as well as avoiding any disruption to their operations. Additionally, a comprehensive roof survey can identify areas of energy loss, helping to reduce energy costs and carbon emissions.
Regular flat roof surveys also help to maintain compliance with building regulations and insurance requirements. Many insurance policies require regular roof inspections to ensure the roof is in good condition and poses no risk of damage to the property or its occupants. Failure to comply with these requirements can result in the invalidation of insurance policies, leaving property owners at risk of financial losses.
Common Issues Found on Felt Roofs
Felt roofs are a popular choice for flat roofs due to their cost-effectiveness and ease of installation. However, they are prone to a range of issues, especially as they age. One of the most common issues found on felt roofs is cracking and blistering. This occurs when the felt becomes brittle and loses its flexibility, resulting in cracks and bubbles forming on the surface of the roof. This can lead to water penetration, which can cause significant damage to the building’s structure and contents.
Another common issue found on felt roofs is deterioration of the felt material itself. This can occur due to exposure to the elements, as well as general wear and tear over time. This can lead to the felt becoming thin and brittle, making it more susceptible to damage and water penetration.
Other issues found on felt roofs include inadequate drainage, which can result in standing water and eventual roof failure, as well as poor installation and maintenance practices, such as the use of incompatible materials and failure to address small issues before they become major problems.
Common Issues Found on Asphalt Roofs
Asphalt roofs are another popular choice for flat roofs, known for their durability and resistance to the elements. However, they are not immune to issues, especially as they age. One of the most common issues found on asphalt roofs is cracking and splitting. This occurs due to exposure to the elements, as well as general wear and tear over time. This can lead to water penetration, which can cause significant damage to the building’s structure and contents.
Another common issue found on asphalt roofs is blistering. This occurs when moisture becomes trapped between the layers of the roof, causing bubbles to form on the surface. This can lead to the roof becoming more susceptible to damage and water penetration.
Other issues found on asphalt roofs include poor installation practices, inadequate drainage, and poor maintenance practices, such as failure to address small issues before they become major problems.
Common Issues Found on Single-Ply Roofs
Single-ply roofs are a popular choice for flat roofs due to their ease of installation and cost-effectiveness. However, they are prone to a range of issues, especially as they age. One of the most common issues found on single-ply roofs is cracking and splitting. This occurs due to exposure to the elements, as well as general wear and tear over time. This can lead to water penetration, which can cause significant damage to the building’s structure and contents.
Another common issue Commonly Found on Asphalt Flat Roofs
Asphalt flat roofs are a popular choice due to their affordability, durability, and ease of installation. However, they are not immune to issues, and a flat roof survey can help identify any potential problems. Some of the most common issues found on asphalt flat roofs include:
Cracks and splits: Over time, the asphalt material can become brittle and crack, which can lead to water penetration and leakage. Cracks can also occur due to poor installation or improper maintenance.
Blisters and ridges: These occur when the asphalt is not applied evenly or when there is moisture trapped between the layers of the roof. Blisters and ridges can cause water to pool on the roof, which can lead to further damage.
Ponding water: This occurs when water accumulates on the roof and does not drain properly. Ponding water can lead to roof membrane deterioration, leaks, and structural damage.
Poor insulation: Insulation is essential for maintaining an even temperature inside a building. Poor insulation can lead to energy loss, increased heating and cooling costs, and even mold growth.
Vegetation growth: The lack of regular maintenance can lead to the growth of vegetation on the roof, which can damage the roofing material and cause leaks.
Issues Commonly Found on Single Ply Flat Roofs
Single-ply roofing systems are made from flexible sheets of synthetic materials such as TPO, PVC, and EPDM. They are lightweight, easy to install, and have excellent waterproofing properties. However, like other types of flat roofs, they are not without their issues. Some of the most common issues found on single-ply flat roofs include:
Punctures and tears: Single-ply roofing materials are vulnerable to punctures and tears, which can occur due to heavy foot traffic, falling debris, or improper installation.
Seam issues: The seams of single-ply roofs are particularly vulnerable to damage and can be a source of leaks. If the seams are not properly sealed, water can penetrate and damage the roof structure.
Ponding water: Like other types of flat roofs, single-ply roofs are susceptible to ponding water, which can lead to leaks and other issues.
UV damage: Exposure to the sun’s UV rays can cause the roofing material to degrade over time, which can lead to cracks, splits, and other types of damage.
Poor installation: Improper installation can lead to a host of problems, including leaks, ponding water, and premature wear and tear.
Conclusion
A flat roof survey is a crucial component of maintaining the integrity and longevity of your flat roof. It can help identify potential problems before they become major issues and can save you money in the long run by preventing costly repairs and replacements.
During a flat roof survey, a qualified professional will assess the condition of your roof, identify any issues, and recommend appropriate solutions. The most common issues found on felt, asphalt, and single-ply flat roofs include cracks, splits, blisters, ridges, ponding water, poor insulation, vegetation growth, punctures, tears, seam issues, UV damage, and poor installation.
By addressing these issues promptly and regularly maintaining your flat roof, you can extend its lifespan and protect your property from water damage, mold growth, energy loss, and structural damage. Remember to hire a qualified professional to conduct your flat roof survey and ensure that any repairs or replacements are done to the highest standard.
Implementing a regular flat roof survey schedule is a small investment that can pay off in big ways by protecting your property, ensuring the safety of its occupants, and saving you money in the long run.
