why should you make a roof waterproofing

It is essential to protect the structure of a building and maintain a healthy and safe indoor environment. There are 3 main reasons to waterproof a roof:

  • Protection against structural damage: If a roof is not properly waterproofed, water could seep in and cause damage to the building structure, such as wood rot and metal corrosion. This damage can be difficult to repair and can jeopardise the stability of the building.
  • Avoid health problems: Water leaks can cause mold and fungal growth, which can have a negative impact on indoor air quality and lead to health problems, especially to people with allergies or asthma.
  • Energy savings: A properly waterproofed roof can reduce the amount of energy needed to maintain a comfortable indoor temperature. If water penetrates the roof insulation, it can decrease its thermal insulation capacity and increase the energy consumption needed to heat or cool the building.

How to make a roof waterproofing:step by step

A roof is one of the most important parts of any structure, as it protects the inside of the structure from the outside elements. However, roofs can be affected by water leaks, which can cause significant and costly damage. Waterproofing a roof is a key process to prevent such leaks and ensure proper protection of the building. In this context, knowing the steps necessary to waterproof a roof, could be useful to any owner or professional involved in the construction or maintenance of structures.

the following detailed steps for roof waterproofing are:

Inspecting the roof

Perform a thorough inspection of the roof to detect any existing waterproofing problems and correct them before the beginning of the waterproofing process.

Cleaning and preparation

The roof surface must be properly cleaned and prepared before any waterproofing is applied. This may include the removal of any mould or moss, as well as the repair of any cracks or damage to the surface.

Material selection

There are different materials and options for waterproofing a roof, such as asphalt sheeting, polymer membranes, waterproofing paints, among others. Select the material that suits your needs and budget best.

Base coat application

Installation of the topcoat

Apply the final coat of waterproofing over the entire roof surface, following the specific instructions of the selected material. Protecting edges and critical points  It is important to protect roof edges and other critical points, such as chimneys or drains, to prevent water infiltration. Use specific materials to protect these points.
