Are you thinking of installing a flat roof for your home or business in Ireland? If so, you might be wondering how much it will cost you and what factors affect the price. Flat roofs are becoming more popular in Ireland due to their durability, versatility, and energy efficiency. However, they also come with different options, materials, and installation methods that can influence the final cost.
This blog post will explain everything you need to know about flat roof cost in Ireland, including the types of flat roofs, the average prices, the cost factors, and the benefits of choosing a flat roof.
Types of Flat Roofs and Their Costs
The first thing to consider when estimating the flat roof cost in Ireland is the type of flat roof you want to install. There are different types of flat roofs, each with its own advantages, disadvantages, and costs.
Here are some of the most common types of flat roofs and their approximate costs per square metre:
Torch-on felt
This is a traditional flat roofing system that uses multiple layers of bituminous felt and asphalt to create a waterproof membrane. Torch-on felt is applied with a torch that melts the material and bonds it to the roof surface. However, it also has a shorter lifespan than other materials, lasting about 15 to 20 years. The average cost of torch-on felt roofing is between €55 to €70 per square metre.
Fibreglass
Modern flat roofing system that uses multiple layers of fibreglass and resin to create a waterproof membrane. Fibreglass is also known as GRP (glass reinforced plastic) or FRP (fibre reinforced plastic). Fibreglass is a strong, durable, and lightweight material that can last up to 25 years with proper maintenance.
It also provides excellent resistance to weather, fire, and UV rays. The average cost of fibreglass roofing is between €70 to €90 per square metre.
Zinc
Metal flat roofing system that uses sheets of zinc alloy to cover the roof surface. Zinc is a natural and recyclable material that has a unique and attractive appearance. Zinc is also very durable and can last up to 60 years with minimal maintenance. It also has excellent thermal and acoustic properties, as well as corrosion and fire resistance.
Zinc is one of the most expensive flat roofing options, but it also offers the longest lifespan and the highest aesthetic value. The average cost of zinc roofing is between €120 to €150 per square metre.
Copper
This is another metal flat roofing system that uses sheets of copper to cover the roof surface. Copper is a premium and elegant material that has a beautiful colour. Copper is also very durable and can last up to 100 years with proper care. It also has excellent thermal and electrical properties, as well as corrosion and fire resistance.
Copper is the most expensive flat roofing option, but it also offers the highest quality. The average cost of copper roofing is between €150 to €200 per square metre.
What Factors Affect the Cost of Flat Roof Installation
The type of flat roof you choose is not the only factor that affects the flat roof cost in Ireland. There are also other factors that can influence the price, such as:
The size of the roof
The larger the roof area, the more materials and labour you will need, and the higher the cost. However, you may also benefit from economies of scale, as some roofing contractors may offer discounts for larger projects.
The condition of the roof
The state of your existing roof can also affect the cost of installing a new flat roof. If your roof is in good condition, you may only need to add a new layer of flat roofing material over it.
However, if your roof is damaged, old, or uneven, you may need to remove the old roof, repair the roof structure, or level the roof surface before installing a new flat roof. This will increase the time, labour, and materials required, and therefore the cost.
The complexity of the roof
The design and shape of your roof can also impact the cost of installing a flat roof. If your roof is simple and rectangular, it will be easier and cheaper to install a flat roof. However, if your roof has curves, angles, slopes, or features such as skylights, chimneys, vents, or pipes, it will be more difficult and expensive to install a flat roof.
You may need to cut, join, or seal the flat roofing material around these features, which will require more skill, time, and materials.
The location of the property
The location of your property can also affect the cost of installing a flat roof. Depending on where you live, you may face different weather conditions, building regulations, and market rates.
For example, if you live in a coastal or windy area, you may need a more durable and resistant flat roofing material, which will increase the cost. Similarly, if you live in an urban or remote area, you may face higher or lower labour and transportation costs, which will also affect the price.
Conclusion
To sum up, installing a flat roof in Ireland is an investment that offers both aesthetic and functional benefits. The cost can vary widely based on factors such as the type of material you choose, the size and condition of your roof, and the complexity of the installation. Whether you opt for a traditional torch-on felt, a durable fibreglass, or a premium metal like zinc or copper, it’s essential to consider both the initial cost and the long-term value.
