Liquid waterproofing is best
Liquid waterproofing is the best and most popular since many years. It is economical as well as environment friendly solution. It is recommended by most of the roofing contractors. Nowadays, it can be done in white color which means it reflects sunlight and keeps the inside temperature cooler. Liquids that are common for roof waterproofing are polyurethane, elastomeric, silicon and more. These materials with a single layer over the roof can last for at least twenty years.
Choose the best material
Any contractor will suggest you several options for it but it is you only who decides the best material that is suitable for your roof and that can fall under your budget. This becomes even important when the roof was coated previously. Don’t choose urethane over elastomeric as it can trigger emulsification. You also need to be cautious if there is silicon coated previously over the roof. It is better to get it removed completely before applying another coat as it can create problem in adhesion.
What to check?
The next thing you can get done is proper priming of the surface. This will improve the strength of adhesion. It is better to keep the surface completely dry before applying the primer. Before the application of waterproofing liquid you must check on the details on the roof such as pipe, vents, drain pipes, all the corners and more, make sure that they are treated with reinforcing fabric or sealant.
