Once flat roofs were notoriously prone to leaking and the problem could only be solved with a boiling cauldron of tar. These days there are patch repair kits, liquid rubber membranes and even quick, efficient waterproofing paint such as paint-on acrylics that last for ages – and can even be applied in damp weather.

Roof waterproofing is the layer of extra protection added to your roof that guarantees no water gets inside your home or starts causing the walls or support beams to rot. There are many causes of roof leaks, with inadequate roof waterproofing at the top of that list.

Water-resistant roofs are also called hydrostatic roofs. They are made from materials like rubber or metal that naturally block water. Low-slope or flat roofs are typically made of water-resistant materials.
