Depending upon the construction of your roof, the materials that it consists of, the pitch(or angles) of your roof, your location in the world among other things, there are several types of weatherproof roofing and exteriors to choose from.

Most roofs have designs that shed water naturally, which is where the pitch comes in. In the case of flat roofs though, there are very few options outside of total weatherproofing. Types of waterproof roofing and exteriors used in these cases consist of everything from bitumen and rubber to Hypalon, polyvinyl, and a wide variety of other materials.

A few of the most common types of weatherproof roofing and exteriors for homes and businesses with flat roofs include the following.

Cementitious waterproofing

Cementitious waterproofing is a product formed by a combination of cement, sand, and latex. Using cementitious waterproofing consists of mixing the materials on site. This is because it dries somewhat quickly. Unlike other types of liquid waterproofing membranes which are pre-made and available for purchasing in buckets ready for use. You then apply it to the roof of your home or business via brushes or rollers.

There is no doubt that cementitious waterproofing is an excellent method of protection for your home or business. The latex adds great flexibility and the waterproofing ability to the mix, the cement obviously adds strength. Using cementitious waterproofing is an excellent choice for flat roofs, and works exceptionally well on cement or ceramic roofs. The lifespan of the average product is 25 years.

Liquid waterproofing membrane

The idea of liquid waterproofing has been around for nearly 200 years. Of course, over the past two centuries, it has become highly evolved from its original form. The liquid waterproofing membrane is now added to practically all types of roofs. That includes any pitch as well as flat or domed roofs as well.

Initially, bitumen, straw, and other human-made materials were mixed together. It was then applied to roofs to attain some better than average level of waterproofing in those times. Now, liquid waterproofing membranes are much more impressive. Most contain polyurethane which is highly waterproof.

Once applied to a roof the liquid mix cures into a waterproof membrane. Today, liquid waterproofing membranes are more widely used as roofing coatings by professional roofers in North America and Europe than just about anything. Roofs coated with a liquid waterproofing membrane typically last up to 25 years or more.

Bituminous sheet membrane waterproofing

Bitumen is, in basics, asphalt(or coal-tar pitch). Professional roofers use bitumen to form the roofs of commercial properties. Using bituminous sheet membrane waterproofing products is much more straightforward and far more effective than the alternative methods. However, it is still a process that requires roofing professionals to complete.

Bituminous sheet membrane waterproofing materials come in large rolls. Professionals first clear the roof of all debris, especially anything flammable, then they unroll and cut the sheets to fit correctly. Next, they use a torch to connect each sheet, creating seamless and completely waterproof joints. Repeating the process several times until the entire surface is smooth. Finally, roll a coat of granules onto the roof. Now the weatherproofing is total and complete.

Polyurethane liquid membrane waterproofing

Roofing professionals the world over rely on polyurethane liquid membrane waterproofing materials for weatherproofing rooftops. Polyurethane liquid membrane waterproofing is universal on residential as well as commercial properties including, homes, businesses, water tanks, ponds, decks and more.

Businesses with flat roofs more often than not choose polyurethane liquid membrane waterproofing to achieve weatherproofing for their building. Apply the membrane during construction, or afterward. There is little more versatile or effective as a weatherproofing agent for roofs than polyurethane liquid membrane waterproofing.

Steps to Installing Weatherproof Roofing and Exteriors to Flat Roofs

The steps to adding a weatherproof membrane to your roof can and will vary depending on the shape, size, and construction of your roof. However, following several steps in most situations for the successful installation of weatherproof roofing and exteriors is possible.

Clean the substrate

Before progressing into installing weatherproofing and exteriors to your building, you will need to clear the roof of all dirt, debris, and flammable materials. This process will rid your roof of potential bond-breakers which cause your membrane not to seal correctly. Most commonly, professionals powerwash the roof for this step.

Prime the substrate

After adequately cleaning the roof, the next step is priming the surface, or substrate, for adhesion of the membrane to be more successful. This step also includes taking the time to pay attention to such details as pipes and vents on the roof. Adding flashing or special fabrics to these areas before continuing is vital to creating a weatherproof seal to the roof.

Apply the membrane

The final step is the actual application of the weatherproof membrane. The materials may come in large rolls, mats, or liquid which needs you to apply with rollers. To apply a liquid membrane, typically two or three coats get rolled onto the roof to achieve the best results. It is entirely vital that each coat dries completely before continuing. Otherwise, the membrane will develop weak spots and may not be 100% weatherproof.
