The “need-to-know” basics of roofing

Are you currently living somewhere? Do you currently have a job? If you were able to answer yes to either of these questions then you have a roof that is over your head at least at one point in your everyday life.  This roof is what is protecting your from bad weather from landing on your head.  That heavy rain or the snow from the winter blizzard will not land on you if you are fortunate enough to have a roof that is over your head.

There are a few things about roofs that will better help you understand their structure.  Every roof contains a trusses.  This is often times referred to as the peak of the roof.  This is where the two angled sides of the roof come up and meet at a point.  A trusses is necessary when you are having a roof replacement installed or building a house for the first time.  The purpose of a trusses is to allow water, snow, or other objects to roll of the sides of your roof.  This way nothing is able to sit on the roof which would then lead to damage of the shingles and then could lead to further damage of the structure of the building or home.

During the roof replacement project you may have seen black plastic that looks like tarp.  This black plastic is put over the trusses and sides of the roof to prevent any water from leaking through the roof.  It is also there to just provide that extra support for the roof.  It can prevent things, such as trees, from causing severe damage to the roof as well.  This black tarp is basically a protectant of the wood structure of the underlying roof.

On top of the black tarp comes the shingles for the roof.  Professional roofing companies offer a variety of different types of shingles.  Based on which type of shingle you have custom chosen for your roof, the shingles will be installed according to that particular style.  You may have chosen either the shingles made of asphalt, metal, tile, or laminate.  The shingles will then be attached to the black paper that is below it.

Typically asphalt shingles or metal roofing is installed slightly different than tile shingles or laminate shingles.  This is because metal roofs contain pieces of overlapping metal.  The same thing goes for asphalt shingles.  The asphalt is usually overlapped.  For these two types of roofs the shingles will be attached to the paper closest to the ground first.  They will then be attached to the paper in layers going upwards until they reach the peak of the roof, also known as the trusses.

No matter which type of shingles that you have chosen to go with for your roofing, they will be attached to the black tarp.  The attachment will go through the black tarp and into the wood trusses and side boards of the roof.  This provides a sturdy foundation for the shingles so that they are tightly installed.  The reason that the shingles need to be tightly secured to the underlying materials is to make sure that they are able to withstand forces from the winds, rain and snow.
