Commercial flat roofs are a popular choice for businesses and industrial properties across the Bay Area. They’re cost-effective, practical, and provide extra space for HVAC units or solar panels. However, flat roofs require proper care to ensure they last as long as possible. Without consistent upkeep, problems such as leaks, standing water, or membrane deterioration can reduce the lifespan of a roof and result in costly repairs.
At Frank Fiala Roofing, Inc. (FFR), we’ve worked with numerous property owners and managers to safeguard their investments. Here are some of the most effective commercial flat roof maintenance tips to ensure your roof stays in excellent condition.
Schedule Regular Roof Inspections
Routine inspections are the foundation of flat roof care. At least twice annually—ideally during the spring and fall—have a professional roofing contractor perform the following:
- Examine the roofing membrane for cracks, blisters, or punctures that could compromise its integrity.
- Inspect flashing and seams for gaps or deterioration
- Identify early signs of leaks or water intrusion
Catching small problems early can save you from major repairs down the road.
Keep the Roof Clean and Clear
Debris like leaves, branches, and dirt can trap moisture, clog drains, and add unnecessary weight. To prevent this:
- Remove debris after storms or high winds
- Clear clogged gutters and downspouts
- Trim overhanging trees near the building
Keeping the roof clean reduces the risk of leaks and drainage problems.
Address Ponding Water Immediately
Flat roofs often experience water accumulation, especially after heavy rainfall. If left unaddressed, ponding water can weaken roofing materials and cause leaks. Maintenance steps include:
- Ensuring drains and scuppers are clear
- Checking for uneven areas or sagging spots
- Having a contractor re-level or reinforce problem areas if needed
Repair Damage Promptly
Even small cracks or punctures can turn into big problems if ignored. Promptly repairing:
- Tears in the membrane
- Damaged flashing
- Loose seams
…can prolong the life of your roof and help you avoid expensive replacements.
Protect Against Heavy Foot Traffic
Flat roofs often house HVAC equipment or are used for maintenance access. Heavy foot traffic can wear down membranes, so it’s important to:
- Install walk pads or pavers along frequently traveled routes
- Limit roof access to authorized personnel only
- Inspect traffic areas more frequently for wear
Plan for Seasonal Maintenance
The Bay Area experiences a range of weather, from heavy winter rains to hot summer sun. Seasonal maintenance should include:
- Checking for UV damage or cracked materials in summer
- Ensuring the roof is watertight before the rainy season
- Inspecting after storms for signs of damage
