Roofs are perhaps the most important part of a
house. But building just a roof is not enough, its proper finishing and
maintenance is something which is of foremost importance. That is why; it’s the
need of time that the roofing contractors must also be familiar with the
concept of roof coating. Roof coating is a monolithic and fully adhered fluid
applied over the roofs. If applied properly, it helps to extend the life of the
roof, ultimately saving the cost of re roofing.
Roofs are perhaps the most important part of a house and
often the most neglected one. Besides all, the most important role that it
plays is of providing protection to the building and its residents. But at the
same time it is the most neglected area of the house because as heard often
“out of sight-out of mind?, the roof is also generally out of sight. One would
not want to go over the roof and examine it for no reason. That’s why, until
and unless it starts leaking, no one pays any attention to the roof or its
maintenance.
There is a long list of materials which are commonly used in
roof construction; it includes metals, plastics, rubbers, fibers, glass, wood,
rocks, ceramics etc. But building just a roof is not enough, its proper
finishing and maintenance is something which is of foremost importance. That is
why; it’s the need of time that the roofing contractors must also be familiar
with the concept of roof coatings.
Roof coating is a monolithic and fully adhered fluid applied
over the roofs. If applied properly, it helps to extend the life of the roof,
ultimately saving the cost of re roofing. It has many outstanding features
which makes it an important component of roof construction and finishing. When
applied over the roof, it acts as a top layer over the underlying roofing
system. Its high elasticity allows it to expand and contract back to its
original position. But being the top most layer asks for tolerating a lot of
environmental effects like UV and infrared, temperature extremities like rain,
hail and the physical damage caused due to these factors. Therefore the roof
coatings are specially manufactured keeping in view all these factors so that
maximal protection is delivered to the roof from these roof weakening causes.
There are many benefits that roof coatings deliver. The most
important benefit is the roof leaks repair feature. If the roof is leaking but
not deteriorated to the extent of replacement, then the roofing cost is
significantly reduced by use of roof coatings. Also some roof coatings are
reflective in nature. They reflect heat and extensively reduce the summertime
cooling costs. The elasticity feature does not introduce cracking on
temperature extremities. Coatings also can serve cosmetic purposes. In some
cases such as beneath a highway overpass, or next to high-rise structures where
roofs are quite visible, coatings serve the purpose of improving roof
aesthetics.
There are many types of roof coatings available in the
market. Some of them include polymer-modified acrylic elastomers and polyureas,
asphalt cutbacks and emulsions, silicones, SPF and high-performance urethanes.
Also if broadly categorized, white roof coatings, tinted roof coatings,
elastomeric, aluminum and metal roof coatings are some of the most commonly employed
roof coatings. All these differ in their features and the roof coating should
be chosen very carefully keeping in view your requirements for the coating and
the roof surface on which the coating is to be applied.
White roof coatings are made opaque and reflective by adding
transparent polymeric materials, such as acrylic, and a white pigment, such as
titantium dioxide. When tints are added to white coatings, we get the colored
coatings. The tinting process greatly reduces the solar reflectance.
Elastomeric roof coatings are very versatile and can be applied on a large
variety of roofs such as single-ply, metal, asphalt, polyurethane foam or
concrete roofs (CSPE, , seamless surface that remains flexible even at low temperatures. It is
also elastic and reflective in nature. They can both be employed in
construction phase or the maintenance phase.
The importance of roof coatings can definitely not be
ignored. Consequently the awareness of different type roof coatings among the
roofing contractors and the building residents is very necessary. Therefore get
yourself well aware of what type of coating you need and the type of roof you
have so that you are able to apply the roof coating which is best for your
roof.
