Modern Roof Restorations
Welcome to the ultimate guide on modern roof restorations! In this comprehensive article, we will walk you through the step-by-step process of restoring your roof to its former glory. Roof restoration has become an increasingly popular alternative to roof replacement, offering a cost-effective solution that extends the lifespan of your roof. As experts in the field, Newcastle Roofers is here to provide you with all the essential information you need to know about modern roof restorations.

Understanding Roof Restoration

Roof restoration, also known as liquid roofing, is a process that aims to renew your existing roof by applying elastomeric roof coatings. Unlike traditional roof replacement, roof restoration does not require the removal or replacement of the entire roof. Instead, it focuses on repairing any damaged or compromised areas and applying a seamless, flexible, reflective, and watertight membrane to protect and enhance the performance of your roof.

The Benefits of Roof Restoration

Modern roof restorations offer a range of benefits that make them an attractive option for commercial property owners and facility managers. Let’s explore the key advantages:

1. Cost-Effectiveness

One of the significant advantages of roof restoration is its cost-effectiveness. Compared to a full roof replacement, which can be expensive and time-consuming, restoration provides all the benefits of a new roof at a fraction of the cost. The labour and material requirements for restoration are significantly lower, resulting in savings of 50-70%.

2. Extended Service Life

Roof restoration systems have the remarkable ability to extend the service life of your existing roof. While the average commercial roof has a lifespan of 20-25 years, a properly restored roof can provide an additional 10, 15, or even 20 years of serviceable life. This means you can delay the need for a costly roof replacement and maximise the value of your investment.

3. Enhanced Performance

Modern roof coatings used in the restoration process are designed to fully adhere to commercial roof surfaces, creating a protective, monolithic, and watertight membrane. This membrane effectively stops leaks and renews the overall performance of your roof. By reducing the need for constant maintenance and repair, restoration systems ensure that your roof remains in optimal condition for an extended period.

4. Energy Efficiency

Roof restoration systems contribute to improved energy efficiency in your facility. The coatings used in the process have excellent reflective and emissive qualities, which significantly reduce the transfer of heat to your building. With increased reflectivity, these coatings can reflect 80-90% of the sun’s UV radiation, reducing the workload on your HVAC system and cutting interior cooling costs by up to 20%.

5. Sustainability

In an era of increasing environmental awareness, roof restoration offers a more sustainable solution compared to traditional roof replacements. Roof replacements contribute millions of tons of waste to landfills annually, whereas restoration requires no tear-off and has a minimal impact on the environment. By choosing restoration, you can contribute to a more sustainable future for our planet.

6. Minimal Disruption

Roof restoration is a far less disruptive process compared to roof replacement. The installation time is significantly shorter, minimising the impact on your day-to-day business operations. This means less inconvenience for building occupants and a quicker return to normalcy.

When to Consider Roof Restoration

Ideally, it is best to consider roof restoration before any significant problems arise. Taking a proactive approach to roof maintenance can help you avoid costly repairs and extend the lifespan of your roof. The earlier you invest in a restoration system, the more likely it is to perform successfully in the long run. However, there are certain criteria that your roofing assembly must meet for a successful restoration:
    • Structural Soundness: The roofing assembly must be structurally sound, with no significant structural weaknesses or safety concerns. It should be free of any wet or saturated insulation, as this can compromise the effectiveness of the restoration system.
    • Minimal Damage: While minor areas of damage or compromise can be addressed during the restoration process, extensive damage may require additional repairs or even a full roof replacement. It is crucial to assess the extent of the damage and consult with a professional roofing contractor to determine the best course of action.
    • Compatibility: The type of roof coating chosen for restoration should be compatible with your existing roofing substrate. Whether it’s metal, modified bitumen, built-up roofs, PVC, TPO, EPDM, concrete, or spray polyurethane foam, the coating chemistry should be suitable for your specific roofing material.
To determine if your roof is a suitable candidate for restoration, it is highly recommended to perform an adhesion test patch. This test will help assess the compatibility and effectiveness of the restoration system on your specific roof.

The Roof Restoration Process

Now that you understand the benefits and criteria for roof restoration, let’s delve into the step-by-step process involved in modern roof restorations. While the exact details may vary depending on the specific project and roofing conditions, the following steps provide a general overview:

1. Roof Inspection and Assessment

The first step in the roof restoration process is a comprehensive inspection and assessment of your roof’s condition. A professional roofing contractor will examine the entire roofing system, identifying any areas of damage, weakness, or potential issues. This inspection helps determine the extent of the restoration required and provides a baseline for future comparisons.

2. Surface Preparation

Once the inspection is complete, the next step is surface preparation. Proper surface preparation is crucial for the successful adhesion of the roof coatings. This typically involves pressure washing the existing roof to remove any dirt, debris, or contaminants that may hinder the coating’s bond. In some cases, a primer may be applied to enhance adhesion.

3. Repairs and Reinforcements

During the surface preparation process, any damaged or compromised areas of the roof will be addressed and repaired. This may include replacing damaged shingles, repairing flashing, sealing cracks, and reinforcing weak or vulnerable sections. It is essential to ensure that the roof is structurally sound and capable of supporting the restoration system.

4. Application of Roof Coatings

Once the surface is properly prepared and any necessary repairs are complete, the roof coatings can be applied. Modern roof coatings come in various chemistries, such as acrylic, butyl, silicone, and urethane, each offering specific benefits and characteristics. The chosen coating is applied using specialised equipment, such as airless sprayers, tank spreaders, or nap rollers, depending on the project’s requirements. The application process typically involves multiple coats to achieve the desired thickness and ensure proper coverage. Each coat is applied evenly, allowing sufficient drying and curing time between applications. The final result is a seamless, flexible, and watertight membrane that provides enhanced protection and performance for your roof.

5. Quality Assurance and Inspection

After the coatings have been applied, a thorough quality assurance and inspection process takes place. This ensures that the restoration system has been properly installed and meets the necessary standards. The inspection may involve visual checks, adhesion tests, and performance evaluations to verify the effectiveness of the restoration.

6. Ongoing Maintenance and Care

Once the roof restoration is complete, it is essential to implement a regular maintenance and care routine to maximise the longevity of the restoration system. This may include periodic inspections, cleaning, and recoating as necessary. Following the manufacturer’s guidelines and working with a professional roofing contractor can help ensure that your restored roof remains in peak condition for years to come.
