Is A Commercial Roof Survey The Same As Commercial Roof Maintenance?

No, a commercial roof survey is not the same as commercial roof maintenance.

A commercial roof survey involves a comprehensive assessment of the roof's condition, typically performed by a professional roofing contractor or inspector. It aims to identify any existing or potential issues, such as leaks, damage, or deterioration, and provides a detailed report of the roof's overall condition. The survey helps building owners or facility managers make informed decisions regarding repairs, maintenance, or replacement of the roof.

On the other hand, commercial roof maintenance refers to the ongoing activities and tasks performed to keep the roof in good condition and ensure its optimal performance. It involves regular inspections, cleaning, repairs, and preventive measures to address any issues identified during the survey or to prevent potential problems from arising. The goal of commercial roof maintenance is to extend the lifespan of the roof, minimize the risk of leaks or damage, and preserve the overall integrity of the roofing system.

While a commercial roof survey provides valuable information for decision-making, commercial roof maintenance is the ongoing process of taking care of the roof based on the survey findings and implementing a planned approach to keep the roof in a reliable and functional state.

What Are The Different Types Of Commercial Roof Survey?

There are several different types of commercial roof surveys:

1. Visual Survey: This involves a visual inspection of the roof's exterior and interior to identify any visible signs of damage, leaks, or wear.
2. Infrared Survey: Infrared thermography is used to detect temperature variations on the roof surface, which can indicate moisture intrusion or insulation issues.
3. Core Sample Survey: Core samples are taken from the roof to assess the condition of the roofing materials, identify layers, and determine their composition.
4. Moisture Survey: This survey uses specialised equipment to detect and measure moisture content within the roofing system, helping to identify areas of potential leaks or water damage.

What Is The Best Type Of Survey For Maintenance Purposes?

For maintenance purposes, a combination of visual and moisture surveys is typically recommended. A visual survey allows for a thorough inspection of the roof's condition, identifying visible damage and wear. Incorporating a moisture survey helps detect hidden moisture and potential problem areas without visible signs of damage. By combining these surveys, building owners can prioritise maintenance efforts. This allows commercial roof repairs to be scheduled to address issues. This extends the roof's lifespan and ensures optimal performance.
