Overview
The basic elements of a preventive maintenance program for roofs are regular visual inspections to determine the current condition of the roof membrane and flashings. Immediate repair of any defect before it allows moisture to enter the roof system or building interior is critical in keeping the roof assembly functioning properly.
At Evans Roofing Company we understand that your roof is a significant investment. Our certified roof maintenance technicians can keep your roof in excellent working condition for years to come. Roof systems, unlike other components of a building are susceptible to severe weathering, expansion, and contraction, human and animal abuse. In addition, exposure to unusual pollutants, strong winds, hail and long continued rains, may result in additional roof system degradation. As a result, building owners and property managers should routinely implement a scheduled roof inspection and maintenance program.
The Evans Roofing Company Preventative Maintenance Process
First, our certified roof maintenance technicians examine the condition of the roof system, evaluating each element for functionality, using a standard process and inspection checklist. Then, we compare the roof condition and function against customer expectations and review the inspection checklist with the customer. Next, we perform minor repairs, which could include resealing terminations, fixing small punctures, replacing missing fasteners, and replacing deteriorated caulking or sealants. Finally, we review the roof assembly current conditions and deliver before-and-after photos with the customer to keep in their records.
Our skilled technicians are able to complete a variety of preventative roof maintenance services including:
1. Remove all debris. Debris such as loose gravel, dirt, leaves, and twigs should be removed. These materials can retain water if left on the roof. The constant moisture can cause damage to the roof, promote growth of algae and mold, and cause standing water to form.
2. Clear drains. Field drains and auxiliary drains should be cleared to prevent ponding that may cause leaks or structural damage.
3. Inspect the roof surface. Perform a visual inspection of the roof system. On single-ply roofs, inspect for holes, cracks, or fastener back-out. On built-up roofs, look for areas with missing gravel or exposed felts. Inspect roof seams and transitions for cracks or holes and have them sealed. This inspection may raise questions about the integrity of the roof membrane that justify a professional examination.
4. Inspect roof penetrations. Roof penetrations include pipes, drains, and other components that protrude through the roof surface. Roof penetrations are highly susceptible to leaks. It is very important to examine HVAC units, conduits, vents, gas lines, rain collars, and pipe boots. If that a roof penetration is leaking or damaged, the problem should be professionally diagnosed and repaired.
5. Evaluate rooftop perimeter. Walk the roof perimeter to inspect the edge details and note any areas of concern, including soft spots, mold, or algae. Inspect the flashing at walls and curbs for any punctures or damage.
6. Inspect the sealant. Keep an eye out for sealant or caulking issues such as cracking, openings, deterioration, or crazing. Sealant failures are often found around penetrations and perimeter flashings. Sealant requires regular inspection and often has to be repaired.
7. Prevent leaks before they start. A roof inspection may reveal areas of deterioration that will require repair. Repairing these small defects before they become major issues will save thousands of dollars down the road. If the damage is beyond the facility staff skill set, or you are uncertain of the proper repair, contact a professional.
8. Perform additional investigations. If the areas of deterioration require additional investigation, consider destructive testing, which requires making an opening for closer inspection, or non-destructive testing, such as infrared scanning, to determine the severity of the issue.
9. Track roof warranty conditions & repairs.
10. Determine if additional work is needed that is not included in the Preventative Maintenance Program.
Summary
Your buildings are a large investment for an owner and to protect that investment and ensure that all of the contents and occupants of the building are safe, the roof needs to be in good condition. Good housekeeping, keeping roofs free of debris and vegetation in conjunction with early detection and repair is critical in maximizing the life expectancies of your roofs. For this reason, it is extremely important to have a preventative roof maintenance program at your facility.
