With temperatures beginning to rise in the UK, your commercial or industrial roofing system may be at risk.

While winter’s cold and rain can damage roofs, the intense summer heat can also cause significant wear and tear, leading to potential issues you might not even notice.

Keep reading for help on preparing your commercial roof for the summer months.

Why do I need to prepare for summer?

Prolonged exposure to heat and sunlight can cause materials like metal, wood, clay, and plastic to expand.

As temperatures drop, these materials contract back to their original size. This constant cycle of expansion and contraction puts significant stress on the roofing materials which gradually weakens and wears out your roofing system over time.

The intense heat can also lead to the formation of cracks in the roof’s surface. These cracks develop as different areas of the roof expand and contract at varying rates. The presence of cracks can compromise the integrity of the roof, leading to leaks that may go unnoticed initially.

During a heatwave, this type of damage can accumulate rapidly, posing a serious threat to the overall durability and effectiveness of your commercial or industrial roofing system.

Regular commercial roof surveys and proactive maintenance are essential to mitigate these risks and ensure the longevity of your roof.

Preparing for the hot weather

While you can’t control the heat, you can take steps to protect your roof from damage:

1. Inspect the roof surface

The roof surface is your first line of defence against the elements. A close-up inspection of the materials can reveal wear and tear in specific areas, allowing for timely repairs or replacements by a professional.

Commercial roofs often have features like skylights, vents, chimneys, or HVAC units that require gaps sealed with flashing. Over time, flashing can crack and become porous, especially during a heatwave.

Don’t worry though, a professional can identify worn flashing and recommend necessary repairs.

2. Install cool materials or coatings

Effective insulation and ventilation play vital roles in minimising heat transfer and reducing the risk of thermal expansion and contraction in your commercial building.

Installing reflective roof coatings or cool roofing materials can help deflect sunlight and decrease heat absorption, resulting in a cooler indoor environment and lower energy costs.

By implementing these measures, you can enhance the comfort of your building while also promoting energy efficiency and sustainability.

3. Clean gutters and drains

Proper water drainage is essential for maintaining the integrity of your roof.

Clogged gutters and drains can lead to water pooling and potential leaks, so it’s crucial to clear out any debris such as leaves, branches, and dirt from gutters, downspouts, and roof drains.

Regularly maintaining your drainage system helps ensure unobstructed water flow, preventing water damage and extending the lifespan of your commercial roof.

4. Trim surrounding trees

Overhanging tree branches can be a significant hazard to your commercial roof, especially during summer storms with high winds.

Removing dead or diseased trees reduces the risk of falling limbs, protecting your roof and property from potential harm.

Trim any branches that extend over your roof to avoid damage or debris accumulation. Keeping the area around your roof clear of such hazards is an important preventive measure.
