Extreme weather events
Climate change has increased adverse weather events like hurricanes, heavy rainfall, and high winds. These adverse weather events can cause significant damage to roofing materials, including shingles, tiles, and membranes. To mitigate the risk of damage, invest in high-quality roofing materials that are explicitly designed to withstand extreme weather conditions.
Heat stress
Rising temperatures can subject your roof to increased heat stress, particularly in urban areas where heat islands exacerbate the effects of climate change. Heat can cause roofing materials to degrade more quickly, leading to premature ageing and deterioration. Consider installing reflective roofing materials or cool roofs to help limit heat absorption and lower energy costs.
UV radiation
Increased UV radiation resulting from climate change can also damage your roof's integrity. Ultraviolet (UV) rays can often cause roofing materials to fade, crack, and become brittle over time. To protect your roof from UV damage, choose materials with built-in UV inhibitors or apply a protective coating that can help prolong its lifespan.
Temperature fluctuations
Climate change can lead to fluctuations in temperature, with warm days followed by cold nights stressing roofing materials. These temperature fluctuations can generally cause roofing materials to expand and contract, leading to cracks, leaks, and other forms of damage. Ensure that your property's roofing system is installed correctly and insulated to minimise the effects of temperature variations.
Increased moisture
Changes in precipitation (moisture) patterns linked to climate change can increase your roof's moisture exposure. Heavy rainfall, snowmelt, and humidity can all contribute to moisture infiltration, leading to mould growth, rot, and structural damage. Routinely inspect your roof for signs of water damage and address any leaks or drainage issues promptly.
Wind damage
Climate change has been linked to a rise in the frequency and intensity of windstorms, which can cause substantial damage to roofing systems. High winds can lift shingles, tear off flashing, and even blow whole roof sections off. Invest in wind-resistant roofing materials and ensure your roof is properly anchored and secured to withstand strong gusts.
Hailstorms
Hailstorms are another common consequence of climate change, particularly in areas prone to adverse weather events. Hail can cause dents, cracks, and punctures in roofing materials, compromising their integrity and leading to leaks and water damage. Consider installing impact-resistant roofing materials specifically designed to withstand hail storms and other forms of physical damage.
Environmental impact
Manufacturing and disposal of roofing materials can have a significant ecological impact, contributing to carbon emissions, resource depletion, and waste generation. Choose sustainable roofing materials made from recycled or eco-friendly materials with a low environmental footprint. Additionally, consider recycling or repurposing old roofing materials to reduce landfill waste.
Maintenance and upkeep
In light of the changing climate, prioritising regular maintenance and upkeep of your roofing system is more important than ever. Schedule annual inspections, cleanings, and repairs to identify and address any issues before they escalate. By staying ahead of maintenance, you can prolong the lifespan of your property's roof and minimise the need for costly repairs or replacements.
Consultation with professionals
If you're unsure about how climate change impacts your property's roof or need assistance with maintenance or repairs, don't hesitate to consult with roofing professionals.
A qualified, licensed and experienced roofing contractor can inspect the condition of your roof, provide recommendations for improvements, and help you develop a comprehensive roofing maintenance plan tailored to your property's specific needs.
Choosing the right roof for climate change
As climate change continually impacts weather patterns worldwide, it's becoming increasingly important to make informed decisions about our homes' materials and design features. One crucial aspect to consider is the type of roof you choose, as it significantly regulates temperature, energy efficiency, and resilience to extreme weather events.

Understand your climate
The first step in choosing the right roof for climate change is to understand your region's climate. Is your area prone to intense heat waves, heavy rainfall, hurricanes, or snowstorms? Different roofing materials and designs are better suited to various climatic conditions, so assessing your local climate is essential before deciding.
Opt for reflective materials
In areas with hot climates or frequent heat waves, opting for reflective roofing materials can help mitigate heat absorption and reduce indoor temperatures. Materials like metal roofs with reflective coatings or white membrane roofs can reflect sunlight away from the property, keeping it cooler and reducing the need for air conditioning.
Consider insulation
Adequate insulation is crucial for maintaining comfortable indoor temperatures and reducing energy consumption year-round. Choose roofing materials with high thermal resistance (R-value) to lower heat transfer between the interior and exterior of your home. Additionally, consider installing a radiant barrier or attic insulation to further improve energy efficiency.
Prioritise durability
With the increasing frequency and intensity of adverse weather events associated with climate change, durability is crucial when choosing a roof. Pick roofing materials resistant to wind, hail, fire, and moisture damage. Metal roofs, concrete tiles, and clay tiles are examples of durable roofing options that can withstand harsh weather conditions.
Ensure proper ventilation
Adequate roof ventilation is essential for preventing moisture buildup, lowering the risk of mould and mildew growth, and extending the roof lifespan. Choose roofing materials and designs that allow proper ventilation, such as ridge vents, soffit, or gable vents. Proper ventilation also helps regulate attic temperatures and improves energy efficiency.
Evaluate long-term costs
While upfront costs are essential when choosing a roof, it's equally important to factor in long-term costs and maintenance requirements. Some roofing materials might have a higher initial cost but offer greater durability and energy efficiency, resulting in lower long-term expenses. Before making a decision, consider the lifespan, maintenance needs, and energy efficiency of different roofing options.
Go green
In response to climate change, many homeowners opt for eco-friendly roofing materials that reduce environmental impact and promote sustainability. Green roofs, which feature living vegetation, provide insulation, absorb rainwater, and lower the urban heat island effect. Solar panels integrated into the roof can also generate renewable energy and reduce reliance on grid electricity.
Consult with professionals
Choosing the right roof for climate change is a significant choice that requires meticulous consideration of copious factors. Consulting with roofing professionals or sustainability experts can provide valuable insights into greener roofing materials and help you pick based on your property's specific needs and priorities. They can assess your home's architecture, local climate, budget, and sustainability goals to recommend the most suitable roofing options.
Stay updated on regulations
As climate change continues to impact building codes and regulations, stay up-to-date about any changes or updates that may affect roofing requirements in your area. Some localities may offer incentives or rebates for installing energy-efficient or sustainable roofing materials, so explore available options and take advantage of any incentives.
Plan for adaptation
With climate change bringing increased uncertainty and variability in weather patterns, planning for adaptation and resilience in your roofing choices is essential. Consider future-proofing your roof by choosing materials and designs that can withstand changing climatic conditions and extreme weather events for years to come.
Seek professional guidance
Climate change poses significant challenges for homeowners in terms of maintaining the integrity and resilience of their roofing systems. By understanding the potential and harmful impacts of climate change on your roof and taking proactive measures to address them, you can make sure that your home remains protected against the elements for years to come.
Investing in high-quality materials, staying vigilant with maintenance, and seeking professional guidance are essential to safeguarding your roof and preserving your home's value.
