Flexible roof repointing, also known as flexi pointing, is a technique that involves the use of flexible materials to secure ridge tiles in place. Unlike traditional cement pointing, which can crack over time due to structural movements or temperature fluctuations, flexi pointing provides an innovative solution that can adapt to these changes which reduces the risk of water penetration and damage to the roof structure.



The materials commonly used in flexible roof repointing include flexible pointing compounds. These compounds stick better and their flexibility allows movement without cracking or breaking the roof.

When it comes to cement roof repointing, the materials used typically include cement mortar mix, water, and sometimes additives like bonding agents or waterproofing compounds to enhance durability and weather resistance. The mortar is shaped and smoothened to ensure proper adhesion and a neat finish.

Cement roof repointing is a labour-intensive task that requires precision and expertise to achieve optimal results. While it may seem a difficult method, professional roofers have the experience and expertise to do it efficiently, ensuring your roof remains watertight and structurally sound for years to come.

When it comes to deciding between flexi vs cement pointing for your roof, it's essential to weigh the pros and cons of each option carefully. Here, we break down the advantages and disadvantages of both materials to help you make an informed choice:

Flexi Pointing

Advantages:

Flexibility

flexi pointing is designed to move with the natural expansion and contraction of the roof, reducing the risk of cracking and water penetration.

Weather Resistance

It performs well in various weather conditions, including extreme temperatures and high winds, maintaining its integrity over time and preventing frequent repairs or replacements.

Easy Application

flexi pointing can be applied quickly and easily, saving time and labour costs during installation or repairs.

Low Maintenance

Once applied, flexi pointing typically requires minimal maintenance, contributing to long-term cost savings.



Appeal

It comes in a range of colours to match different roof types, enhancing the overall appearance of your property.

Disadvantages:

Initial Cost

Flexi pointing may have a higher initial cost compared to cement, although the long-term benefits often outweigh this initial investment.

Cure Time

It may require sufficient curing time before it reaches its maximum strength applied to wet bedding.

Cement Pointing

Advantages:

Durability

Cement pointing is known for its durability and strength, providing excellent long-term protection against weathering and wear.

Traditional Look

It offers a classic, traditional look that complements various architectural styles, adding to the curb appeal of your property.

Cost-Effective

It is more affordable, in terms of upfront cost, compared to flexi pointing, making it a budget-friendly option for homeowners.

Disadvantages:

Susceptible to Cracking

Cement pointing may crack over time due to temperature changes and structural movement, requiring periodic maintenance and repairs.

Limited Flexibility

Unlike flexi pointing, cement pointing lacks flexibility, which may lead to issues with expansion and contraction, especially in regions with extreme weather conditions.

Labour Intensive

Application and repairs of cement pointing can be labour-intensive and time-consuming, potentially increasing overall project costs.
