3 reasons you should update your roof coating

Is your roof starting to look worse for wear? You probably need to consider applying a new roof coating. Don’t wait to perform this simple but important task. Here are 3 reasons you should update your roof coating as soon as possible. 

1. Waterproofing: this is the most important function roof coating products like Roofite perform. If you’ve been patching holes in your roof every year and hoping for the best, roof coatings will solve this problem. A rubberized asphalt roof coating that’s easy to apply provides a long lasting repair solution for your roof. Instead of torches and asphalt kettles, you simply apply it with a brush, roller, or notched squeegee depending on the surface type of your roof and allow it to fully cure. Roof coatings prolong the life of your roof by weathering the elements and bridging cracks, so that you’re not constantly worrying about leaks and damage, and you also don’t need to be performing regular repairs anymore. 

2. Heat reduction: when you apply a roof coating like Roofite Solar Reflective to your roof, you can expect the summer temperature in your facility to drop substantially. White roof coating products act as a reflective surface, sending heat from the sun’s rays away from your building rather than absorbing it like a black surface would do. This keeps the heat from increasing in the ceiling of your space and reduces the amount of work your air conditioners are required to do to keep the building a cool, comfortable, and safe workplace for your employees. 

3. Money and energy savings: we all know that everything used in a business has to fit with the bottom line somehow. The small investment you’ll make in roof coatings has a big payoff. By using your roof coating as a long-term repair solution, you’ll avoid the cost of having to do those annual patches, and you’ll be protecting your roof so that total roof replacement is much further off in the future rather than an impending expense. In addition, by reducing the temperature of your facility with a white roof coating, you’ll lower your energy usage and utility bills significantly.

Why should I choose a waterproof coating?

Using Watco Roofite®, which is a mixture of bitumen, rubber and fibre, will quickly waterproof leaks and help to extend the life of your roof. 

Watco Roofite® can be used on concrete, corrugated iron, tiles and matted surfaces; it is also an excellent solution for emergency roofing repairs to small areas.

How can I repair a roof using Watco Roofite®?

Watco Roofite® is a roof coating which is simple and easy to use, even when it is raining. Brush apply generously at one kilogram per 1 sq m on the surface and add a second coat if needed. 

If there are cracks or holes in your roof, use Watco Roofite® Repair Mortar, applied with a brush or trowel to fill them. 

For covering a large area of a roof quickly and easily use Watco Roofite® Pour and Restore. This thick, flexible waterproof coating bridges minor cracks and splits.

What available anti slip solutions are there for roofs?

How do I waterproof a roof using Liquid Roof Membrane? (do we need?)

Watco Waterproofing Membrane is a self adhesive, bitumen based product that can be used on balconies, terraces and roofs.

To ensure a smooth, clean finish use a waterproof membrane primer, before applying the Watco Waterproofing Membrane with a rubber roller. It can be used on concrete and on metal or wooden surfaces. 

If Watco Waterproof Membrane is applied externally, it is necessary to apply a UV protection in the form of a top sheet, with stone chippings on.

How do I seal a flat roof?

Watco Waterproof Membrane can be used to seal flat roofs. It is a self-adhesive waterproofing sheet made of elastomeric bitumen with a plastic foil surface on top. 

The membrane can easily be cut to size on site, making it versatile and easy to use. To ensure a good bond, the self-adhesive side tabs should be overlapped using pressure applied from a rubber roller.

What's the best way to repair a roof quickly?
