Roof repointing might not be something you think about often, but it's an extremely important task that keeps your roof in tip-top shape. In this article, we will delve into the details of what roof repointing is, why it is necessary, and the process of how it is done.
We’ll also discuss the costs involved in repointing, as well as the importance of regular maintenance so as to provide you with a much better understanding of why keeping your roof in good condition is absolutely essential.
What is roof repointing?
Roof repointing, also known as re-bedding, is the process of repairing and replacing the mortar between the bricks or tiles on a roof. The mortar is the substance that holds the bricks or tiles together and seals the gaps between them. It is essential for protecting the roof from water infiltration and other external factors.
The process of roof repointing typically involves chipping away the old mortar using a hammer and chisel and cleaning the joint thoroughly before applying the new mortar. The new mortar is then smoothed and finished to match the existing mortar as closely as possible.
Roof repointing is necessary because the mortar on a roof is exposed to the elements on a daily basis. Rain, snow, wind, debris, and sun can all take their toll on the mortar, causing it to wear down over time. As the mortar deteriorates, it can lead to gaps and cracks that allow water to penetrate the roof. This can cause damage not only to the roof itself but also to the structure of the building and the possessions inside.
Regular roof repointing can help prevent these issues and extend the lifespan of a roof.
How is roof repointing done?
The process of roof repointing typically involves the following steps:
1. Assessing the extent of the damage and determining the best course of action
Before any work can begin, a professional roofer will inspect the roof to determine the extent of the damage and the best course of action. This includes assessing the condition of the existing mortar and identifying any areas that need to be repaired or replaced.
2. Removing the old mortar and preparing the surface for the new mortar
Once the plan of action is set, the old mortar is removed by chipping it away using a hammer and chisel. It's important to remove all loose, deteriorated or cracked mortar. It's also important to clean the joint thoroughly before applying the new mortar. This will ensure that the new mortar adheres properly and provides a strong, watertight seal.
3. Mixing and applying the new mortar
Next, the new mortar is mixed according to the manufacturer's instructions. The new mortar is then applied to the joint using a trowel. It is important to ensure that the new mortar is packed tightly into the joint and is level with the existing mortar.
4. Finishing and smoothing the new mortar
Once the new mortar is applied, it is then finished and smoothed to match the existing mortar as closely as possible. This ensures that the repair is as invisible as possible and that the roof maintains its aesthetic appeal.
It's recommended that you hire a professional for this task, as it requires skill and experience to ensure that the repair is done correctly and that the roof remains watertight.
Cost of roof repointing
The cost of roof repointing can vary depending on several factors, including:
Size and pitch of the roof
The larger the roof, the more mortar that needs to be removed and replaced, which can increase the cost of the project. The pitch of the roof can also affect the cost, as steeper roofs can be more difficult and dangerous to work on.
The extent of the damage
The more extensive the damage to the mortar, the more work will be required to repair it, which can increase the cost of the project. If the damage is limited to a small area, the cost will be lower than if the damage is widespread.
Type of material used for the new mortar
The type of material used for the new mortar can also affect the cost of the project. Some types of mortar are more expensive than others, and the cost of the materials will be included in the final cost of the project.
Professional labour costs
The cost of professional labour can also be a significant factor in the final cost of the project. A professional roofer will have the necessary equipment and expertise to complete the job safely and correctly, which can add to the cost.
It's difficult to give an estimate without assessing the specific situation of the roof, but generally, the cost of roof repointing can range from a few hundred dollars for small repairs to several thousand dollars for larger projects. It's always recommended to get a professional assessment and an estimate for the cost of the project.
Does your roof need repointing?
Roof repointing is a vital aspect of maintaining the integrity and lifespan of a roof. Without proper repointing, the roof may become vulnerable to leaks, structural damage, and other issues that can lead to costly repairs or even replacement.
It's important for homeowners and building managers to schedule regular inspections and repairs to ensure that their roofs remain in good condition and continue to provide the necessary protection for their homes and businesses. It's also important to hire a professional to ensure that the repair is done correctly and that the roof remains watertight.
