Lack of Proper Planning

One of the most common mistakes DIY enthusiasts make when installing a roof is rushing into the project without adequate planning. Proper planning involves assessing the roof's condition, understanding the required materials, estimating the project timeline, and organising the necessary tools. Skipping these essential steps can lead to delays, cost overruns, and even compromise the roof's integrity.

To avoid this mistake, take the time to research and educate yourself about the roofing process. Create a plan that includes measurements, material calculations (why not check out our handy roof calculator!) and a step-by-step installation guide. By doing so, you'll have a clear roadmap to follow, reducing the chances of errors along the way.

Common mistakes include improper nailing, incorrect placement of underlay, inadequate ventilation, and poor flashing installation.

Ignoring Safety Measures

Safety should always be a top priority during any roofing project. Unfortunately, many DIY enthusiasts neglect safety measures, leading to accidents and injuries. Falling from heights, improper ladder usage, lack of protective gear, and electrical hazards are just a few risks associated with roofing installations.

Always prioritise safety by using appropriate personal protective equipment (PPE), depending on the nature of the project in hand, Consider protective wear such as helmets, gloves, and non-slip shoes. Ensure that your ladder is stable and positioned correctly. If needed, enlist the help of a friend or family member to provide assistance and supervision during the project. By taking the necessary precautions, you'll safeguard yourself and others involved in the roofing installation.

Poor Quality Roofing Underlay

The underlay is a critical component of any roofing system, providing an additional layer of protection against moisture and leaks. However, some DIYers make the mistake of using low-quality or incorrect underlay materials, compromising the roof's integrity.

A key advantage of Onduline’s underlay is the lightweight nature. We employ advanced manufacturing techniques to create underlays that are easy to handle and install, reducing labour and transportation costs. The lightweight design also puts less stress on the roof structure, resulting in improved safety and longevity.

ONDUTISS AIR for Underlay range

ONDUTISS AIR is a high-quality underlay used in many different roofing installations. It is a high-performance, nonwoven, breathable membrane that is designed to protect the roof structure and interior of a building from moisture and water damage.

One of the main benefits of ONDUTISS AIR is that it is breathable, meaning that it allows moisture vapour to escape from the building's interior while preventing water from entering. This helps to prevent the build-up of moisture in the roof structure, which can lead to mould and rot. A must-have for DIYers undertaking a new roofing installation!
