Roof in poor condition: The Risks
Many homeowners wonder why it is necessary to have a roof redone. The roof is the element that insulates your house and protects it from rain, snow, frost, or even wind. It is therefore essential not to neglect the roof of your house in order to keep it in good condition and avoid many risks for the building.
Water leaks, infiltration, stains on the ceiling, bad odors, or even mold are some of the signs that your roof is damaged and is no longer waterproof. It will be necessary to review the waterproofing of the roof. Generally, the roof in poor condition presents risks for your home which are increasing.
Indeed, a simple leak spotted late or left as it is, can result in serious consequences if nothing is done. It could just be a few cracked tiles or a more serious waterproofing or insulation problem. Whatever the cause, water produces effects that can ultimately affect the strength of the walls, ceilings, and floors of the house. It is therefore the entire structure of your home that can be affected by leaks in your roof and therefore greatly increase repair costs.
A roofing problem can cause damage to the interior of the house but can also be a gateway for pests. Small rodents can then enter your home through the roof. To avoid these risks and heavy work, you should therefore remember to check the condition of your roof every year.
In addition, the roof contributes greatly to the comfort of the house. In addition to water infiltration, it is also the guardian of the heat in your interior. As a reminder, 30% of the heat can escape through the roof. Again, when the roof is in poor condition, the insulation no longer plays its role. In fact, the heat escapes, and you are forced to use more energy to maintain a semblance of comfort in your home. The immediate consequence is a significant increase in your heating bill.
Renovation: Possible work to renovate its roof
As you can see, doing nothing when your roof is in bad condition is a very bad idea with sometimes very serious consequences. Also, be aware that there are different solutions depending on the cause and extent of your roofing problem. The renovation can be partial or total or even be limited to a simple repair depending on the nature of the degradation. The objective of the work to renovate a roof is to ensure the waterproofing of the roof. Our pros, therefore, show you the right methods to adopt depending on your roofing problem.
Roof renovation: Repair and replacement of damaged cover
The covering of your roof can quite simply present damaged places. In this case, you only have a few tiles to replace or repair: the sun will cause the tiles to expand and the cold will cause them to contract. Also, it happens that some tiles burst or crack under these actions which leads to leaks and water infiltration points. It is then sufficient to replace the broken tiles to restore the waterproofing of the roof.
In the event of strong gusts of wind or storms, it may happen that tiles fly away. You will then need to lay new tiles in place of the old roofing materials. In the most extreme cases, the cover can be torn off due to bad weather.
Roof renovation: Cover replacement
The problem may be more extensive and in this case, it will be necessary to replace the complete cover. This is often the case when a roof has been poorly maintained and is covered with lichens and moss. By force, the tiles have become porous and allow cold to pass through like water. It will be possible to clean the roof or treat the cover, but a worksite to replace the cover will be compulsory one or two years later.
If you need to redo the roofing entirely, you will need to hire a roofing company to remove the damaged roofing and install the new roofing material.
You can choose to redo it identically or to change the appearance of your roof and opt for another coating if your (Local Urban Plan) allows it. For example, you can change the terracotta tiles with slate to change the exterior appearance of the house. If the appearance of the roof changes, be aware that you will need to submit a prior declaration of work to your town hall.
Roof renovation: Total repair of the roof with insulation work
If the replacement of the roofing is not sufficient, a total repair of the roof must be carried out. This means that it will also be necessary to redo the insulation from the outside and to install a screen under the roof to ensure waterproofing in addition to changing the cover. This work is necessary when the roof is really in very bad condition and the insulation is also very damaged.
In the worst case, you will also have to renovate the frame in addition to repairing the roof with insulation. This may involve taking over the frame in order to treat it or restore it to good condition or even replace certain parts of the frame.
Even if it remains the most expensive work, this project allows insulation to be carried out from the outside of the building, which remains the most efficient solution in terms of thermal and sound insulation. Indeed, with it, there are no thermal bridges. If you plan to have a complete roof renovation, it is important to take advantage of this work to put in place an under-roof screen. The additional cost associated with insulation work from the outside will quickly pay for itself.
Price of a roof renovation according to the technique
To give you an idea of the price of a roof renovation, here are the prices per m² depending on the technique to be used. You will then just have to multiply by the area of your roof to obtain the approximate amount of the work envisaged.
How to choose the method of renovation to be carried out?
You now know the different techniques for redoing a roof. So how do you choose between simple repair, replacement of cover, and total repair? The renovation method to be carried out depends directly on the situation of your roof. Either the age of your roof, the general condition of the roofing materials, and the problems to be repaired.
Therefore, it all depends on the condition of your roof. It is she who will dictate the method to be used. If it is only part of the roof that has problems, it will be necessary to see if you can save part of it and therefore only have a light roof repair to do. If all the tiles are damaged, you will have to opt for a change of cover. Finally, if the tiles and insulation need to be redone, a complete repair with insulation is to be expected.
