Some Key Points You Should Know Before...

Waterproofing the roof is a very important task, both for insulation against cold and heat, and for protecting the structure. In fact, when we want to waterproof a building’s roof, we need to find roof waterproofing material suited to the purpose. This refers to the type of surface and previous roof waterproofing. Note that the waterproofing contractor works according to Israeli standards. Care must be taken that roof waterproofing materials are not hazardous. For example, at one time it was common to waterproof roofs using asbestos panel roofs which are very dangerous to human health, but today these roofs are no longer used.

We all remember the tar that was commonly used several decades ago to waterproof roofs, but today there is a roof waterproofing material that is much more effective and common – bituminous sheets. This is the most efficient and best method, with a 10-year warranty for this waterproofing, indicating strong waterproofing sheets. The prominent advantage is no maintenance required for roofs with bituminous sheet waterproofing. The home stays warm in winter and cool in summer. It should be known that the sheets must suit the surface type and of course the previous waterproofing type.

Acrylic Roof Waterproofing Materials

It should be noted that there are different types of materials intended for roof waterproofing, for example the second material is acrylic roof waterproofing. This refers to fast-setting plastic waterproofing material that can be spray-applied or brushed onto the roof. Care must be taken that roof slope is standard, allowing water drainage into the drainage holes, since the effectiveness of acrylic material for dampness is lower than other waterproofing materials.

Polymer Roof Waterproofing

It should be noted that waterproofing material selection for roofs is based on various conditions, surface etc. Polymer waterproofing suits roofs that cannot be waterproofed using bituminous sheets. Polymer waterproofing has advantages, the prominent one being flexibility, allowing it to contract, stretch and adapt perfectly to weather conditions. This is low maintenance waterproofing material, but the roof must be well prepared and the waterproofing applied onto a clean substrate, improving adhesion of this waterproofing material to the roof.

PVC Sheets for Roof Waterproofing

PVC sheets are made of synthetic material, used for a variety of industrial and roof waterproofing purposes. These sheets adhere to the roof with no need for welding like bituminous sheets. Their waterproofing maintenance is fairly easy. Note that the waterproofing work should be performed by a professional waterproofing contractor, since waterproofing work is highly complex, requiring extensive experience for application.
