Is A Roof Coating The Same Thing As Weatherproofing?

commercial roofing waterproof vs coating

Not all roof coatings are designed to be weatherproof; some are just reflective, protecting the roof against UV radiation and maintaining a nice indoor thermal comfort.

Weatherproofing, on the other side, suppose the application of a fully reinforced layer that provides the roof the strength to seams, blisters, splits, as well as the contraction and expansion stresses. Roof coatings that are not reinforced are more than 8 times weaker than reinforced systems. Although both of the Parker roofing solutions protect the roof`s integrity and structure in their own way, weatherproofing can work as a standalone roof system; reflective coatings cannot.

Weatherproofing a flat roof can be performed in three ways, depending on your budget, the size of the roof and other factors:

Using reinforced bitumen membranes (laying down 2-3 layers of the material, bonding everything together by hot bitumen and combine the coating with a polyester carrier)

Using liquid waterproofing such as glass reinforced plastic that uses rigid polyester resin combined with glass fiber reinforcement. Fleece liquid membranes are a version of liquid waterproofing, featuring liquid resin and fleece reinforcement. Other systems commonly applied are acrylic, polyurethane and flexible polyester systems that are rather used in the roof repair/ maintenance process, because they are not always reinforced.

How Often Should Homeowners Inspect Their Roofs?

Image
It is highly recommended to inspect your roof at least twice a year, in spring and in the fall, plus any time the weather is mild and allows you to do the proper inspection. Mild weather is a great time for inspecting your roof because it makes the job a lot easier, while also helping you prepare in advance, for the upcoming potential hazards or unwanted phenomena that can work havoc on your roof and threaten the safety of your home. Roof inspections should definitely be performed before hail or wind, as these two elements are likely to cause unwanted damage. Even new roofs should be inspected after these two types of events. Another question that arises is whether you should do the inspection on your own, or ask for help from the part of professional Lakewood roofers . The idea is, in case you decide to do it on your own, this may cause you to lose warranties and therefore have problems in the future.
