How Often Should a Commercial Roof Be Cleaned?
Your commercial roof does more than just keep the rain out — it protects your business, employees, and equipment from the elements. Keeping it in top shape means regular maintenance, including cleaning services. But how often should a commercial roof be cleaned, and what factors should influence your cleaning schedule?
Let's explore everything you need to know about commercial roof cleaning.
Why Is Commercial Roof Cleaning Important?
Cleaning your commercial roof is about more than just aesthetics. It plays a crucial role in extending the life of your roof, preventing costly repairs, and maintaining the structural integrity of your building. Here's why regular roof cleaning matters:
- Prevent Damage: Debris buildup, algae, mold, and dirt can trap moisture and lead to roofing material degradation over time. Regular cleaning services can also help your roofing professionals catch emerging problems early, preventing damage before it starts.
- Improve Energy Efficiency: A clean roof reflects heat more effectively, reducing energy costs in the summer months.
- Meet Warranty Requirements: Many roofing warranties require periodic cleaning and maintenance.
- Avoid Structural Issues: Neglecting your roof's cleaning schedule can allow small problems to escalate into major issues, such as leaks or compromised insulation.
- Enhance Curb Appeal: A clean roof contributes to the overall professional appearance of your building.
How Often Should a Commercial Roof Be Cleaned?
The general recommendation for commercial roof cleaning is once every 3 to 12 months. However, the actual need for roof cleaning services depends on several factors, including the type of roof, the local climate, and the surrounding environment. Here are some essential considerations to help you determine the best cleaning schedule for your roof:
1. Climate and Weather Conditions
In regions with heavy rainfall, high humidity, or frequent storms, cleaning may be required every 3 to 6 months to prevent moss, algae, and debris buildup. Meanwhile, in drier climates, an annual cleaning may suffice.
2. Roof Sloping
Commercial buildings with flat roofs are more prone to water pooling and debris accumulation, necessitating more frequent cleaning (typically every 6 months).
Sloped roofs often require less frequent cleaning, as water and debris can naturally roll off. However, this does not necessarily make sloped roofing superior, as these buildings often require gutter cleanings and other associated maintenance considerations.
3. Location and Surroundings
If your building is near trees or industrial areas, you may need to clean your roof every 3 to 6 months to remove fallen leaves, branches, and pollutants. Otherwise, debris and contaminants can pile up on your roof — trapping moisture, promoting mold growth, adding unnecessary structural weight, and creating an environment for damage. This issue also adds texture to the roof, which collects more debris in a self-perpetuating cycle.
4. Roofing Material
Your roofing material (whether it is TPO, EPDM, built-up roofing, or modified bitumen) may have unique cleaning requirements based on its composition and susceptibility to dirt, algae, and wear. You can explore the maintenance requirements of common commercial roofing materials in our guide here.
5. Maintaining a Warranty
While you might think a brand new roof is protected from damage, these are still essential to clean. Not only can cleaning help protect your investment, but it can also keep your warranty intact. Your necessary cleaning routine may vary depending on what is outlined in your warranty agreement.
Signs Your Commercial Roof Needs Cleaning
Even if you have a regular cleaning schedule in place, it's essential to look out for signs that your roof might need immediate attention:
- Debris Buildup: Accumulation of leaves, branches, or trash.
- Visible Algae or Moss: Green or black patches forming on the roof surface.
- Water Pooling: Standing water after rainstorms.
- Damaged Membranes: Cracks, tears, or discoloration in roofing materials.
- Unusual Odors or Stains: Foul smells or water stains inside the building.
If you're unsure about the maintenance needs of your roof, consult a trusted roofing professional (like those at Allied Roofing) to create a personalized cleaning and maintenance plan.
