Autumn roof maintenance checklist for commercial properties

As the days grow shorter and the weather cools, autumn is the perfect time to make sure your commercial and industrial roof is ready for the harsh winter months ahead.

Proactive maintenance during this season can help prevent costly repairs and disruptions to your operations later on.

To help you safeguard your roofing system, we’ve compiled a comprehensive autumn roof maintenance checklist for commercial and industrial buildings.

1. Clean gutters and drainage systems

Falling leaves and debris can quickly block gutters and drainage systems.

When these systems are clogged, water can back up, causing damage and increasing the risk of ice dams as temperatures drop. Water pooling on flat roofs, common in commercial structures, can lead to leaks or structural damage.

Make it a priority to inspect and clean gutters, downspouts, and internal drainage systems regularly to ensure water flows away from your building efficiently.

2. Trim overhanging trees

Trees near your building can be a hazard to your roofing system. During strong winds or heavy rainfall, overhanging branches may break off and damage your roof.

Leaves and organic debris from nearby trees can also accumulate on flat roofs, encouraging the growth of moss, algae, and mould.

Getting these trees trimmed back will help protect your roofing system and prevent damage that could disrupt your business operations.

3. Inspect roof penetrations and flashing

Roof penetrations, such as vents, skylights, and HVAC equipment, are common points of vulnerability where leaks can develop.

The flashing around these penetrations should be checked for signs of wear or damage, particularly after heavy rains. Properly maintained flashing will help keep water from entering your building, protecting both the structure and the assets inside.

If you notice any issues with flashing or roof penetrations, addressing them immediately will help avoid major repairs and downtime.

4. Assess roof insulation and interior ceilings

Roof insulation plays a critical role in maintaining energy efficiency in commercial and industrial spaces.

Inspect the insulation in your building for any signs of water damage, damp spots, or mould, which could indicate a roof leak. Water stains or uneven temperatures in large warehouses or office spaces could signal insulation issues that need to be addressed before winter sets in.

Proper insulation ensures not only energy savings but also long-term protection against structural damage.

5. Apply preventative roof treatments

To maintain the longevity of your roof, consider applying a preventative treatment, especially if the roof you’re working with has flat or low-slope sections.

Moss, algae, and mould growth are more common in damp environments and, without treatment, they can cause significant damage over time.

Applying a moss and algae inhibitor can help protect your roof and extend its lifespan, keeping it in optimal condition before the harsh winter months.

6. Schedule a professional roof survey

While some tasks can be managed in-house, a professional roof survey is the best way to ensure your commercial roof is fully prepared for winter.

A thorough inspection by a trusted roofing contractor like NWIR can identify potential weak spots, from drainage problems to issues with flashing or insulation.
