What is the best waterproofing for roofs?

The purpose of waterproofing is to prevent water from passing through the roof and causing structural damage or affecting the condition of the goods inside the house. For this reason, the current market is focused on systems that increase the resistance of the materials.

Factors such as the passage of time and weather conditions are determining factors in the condition of roofs, so frequent maintenance is essential to prevent leaks, avoid moisture stains and cracks in the surface.

In this sense, when choosing the waterproofing system for the roofs of your home, you should consider, in addition to the climate, the design of the roofs of your home, since it is different to have a gable roof, with a good fall, than a flat roof.

The quality of the products used in the waterproofing will determine the useful life of the waterproofing, so it is not advisable to skimp in this regard.

Waterproofing Materials

Waterproofing materials can be natural, synthetic, metallic or stone, which have different costs and are applied in different ways.

Acrylics

Acrylic products are applied as if they were painted from the outside. They are formulated with resins, which can be acrylic, synthetic or fiberglass.

Asphalts

Asphalts materials provide resistance and offer good durability. They are made with emulsified water, fiberglass and polyester.

Cementitious

Waterproofing with cementitious products are perfect for homes in cold climates. They are very durable and prevent saltpeter from forming on the surface.

Elastic

Ideal for warm climates, elastic materials are made with acrylic copolymers that offer better contraction and expansion than other materials.

Liquid Membranes

Liquid membranes themselves are only intended to be used prior to the polymer coating. However, it is a durable and flexible product.

Polyurethane Membranes

Used for waterproofing moisture-prone materials.

To choose the right material for waterproofing, it is recommended that you consult with our experts, as depending on various factors, some may be more effective.

Liquid Roof Waterproofing Systems

The liquid roof waterproofing system forms a highly durable waterproof film and consists of several layers:

Support, which will serve as a waterproofing base.

• Primers, to improve the adherence between the substrate and the waterproofing,
• High resistance fibers, made of materials such as polyester, polypropylene or glass, which provide resistance, good thickness and are efficient in certain points of the surface, often used to repair cracked surfaces.
• Protection: which prevents separation from the substrate and provides protection from weather or mechanical damage.
• Finishing: improves the appearance of the waterproofing and provides an additional finishing layer.

How To Achieve A Good Waterproofing?

The best way to obtain good results in a waterproofing, not only depends on the materials, also the method of application of the materials is fundamental, for that reason, it is advisable that you contact our experts so that the waterproofing works guarantee optimal results.

All waterproofing work involves:

• Cleaning:It is essential to clean the area to be waterproofed, eliminating dust residues or any other material such as oil, grease, fungus, rust, which may affect the adherence of the material. It is of great importance to check if there are any remains of the previous waterproofing material, verify its condition and if it has deteriorated, it must be eliminated.
• Repair of cracks. In case there are visible damages or cracks, they must be repaired before the application of the waterproofing, therefore an inspection of the entire surface is of vital importance.
• Sealing of the surface: the application of the acrylic sealer, without dilution, must be done in a uniform layer, and it is necessary that it dries completely before proceeding.
• Waterproofing: first the most critical points are waterproofed by applying abundant material, then a mesh or reinforcing fabric is placed and a layer of waterproofing is applied again. It is necessary to avoid the presence of bubbles or wrinkles that can cause later problems. Next, the entire surface is waterproofed and using a brush, the fibers are arranged to provide uniformity. This process requires the previous drying of each layer.

Aspects That Can Affect Waterproofing Quality

One of the biggest drawbacks that arise when you do not hire specialized services, such as ours, is the quality of the products and their expiration date. You should know that a product that is on its expiration date will affect the efficiency of the results.

Another factor that affects failures in the waterproofing process is the lack of knowledge of the products, their effectiveness or the lack of experience in their application. Avoid doing this type of work on your own or hiring personnel without certifications, which far from solving a problem, will create other worse ones.

Using an inadequate material for the surface to be waterproofed can affect the waterproofing, since there are specific products according to the material of your roof and not all products offer the same water absorption capacity or permeability.

High temperatures can affect the waterproofing materials, in case of extreme temperatures, it is necessary to use a flexible waterproofing that supports the contractions and expansions of the surface.

In Bellcast Construction LLC, we offer you the best alternatives for waterproofing, with first quality materials and certified workmanship. Hiring our services you have nothing to worry about, all our jobs are fully guaranteed, and we adjust our rates, reducing our profit margins, without affecting the quality of the work.
