There are a number of factors to take into consideration when it comes to replacing or repairing a commercial roofing system, such as condition, age
and the amount of damage to the existing cover. So if the damage is not extensive all you need to do is hire a commercial roofing Atlanta company to perform repairs. It is also advisable that when the professional team from the commercial roofing Atlanta business begins the repairs to ask them to
additionally fasten the roof cover along the perimeter and in the corners in order to provide greater resistance in the areas exposed to the wind.

If the damage to the roof is extensive then the crew from the commercial roofing Atlanta Company you’ve hired will replace the roof cover
completely. An exception to this action would be if the roof cover is already made out of two or more roof covers.

Furthermore, before starting this type of project, it is mandatory to understand the existing roof’s resistance to severe hurricanes and windstorms
and check to see if the actual roof contains moisture. This inspection can be performed with an infrared thermograph that will determine temperature
differences. Usually wet insulation appears warmer than dry insulation. Nevertheless, this doesn’t always correlate with the amount of moisture in
the roof cover. Another method to measure moisture in commercial roofing is by electric capacitance which measures the difference in a roof
assembly’s dielectric constant. Typically moisture affects the cover’s dielectric constant. Taking a nuclear moisture survey can also detect
hydrogen, which is the primary component of water. So this type of test is also suitable to determine moisture in a roof cover. After testing all
the wet materials and insulation must be removed and replaced before reroofing.

Another test that must be performed before deciding to repair or replace the cover of a roof is related to the roof’s cover ability to withstand
uplift pressures and forces that are correlated with hurricanes and windstorms. Even if the roofing was able to withstand a few storms, multiple
exposure to this kind of natural phenomenon can damage it and reduce future performance of the cover. A roof cover performance can be measured with
uplift tests in the perimeter, the corners and the field of a roof. The test uses a plastic “dome” shaped device that creates suction on the roof
cover. This type of test is also known as the “bubble” test.

A bonded uplift test can also determine the roof’s cover ability to withstand windstorms and hurricanes, but it is a little bit more time consuming
because it uses small pieces of plywood that are bonded to the roof’s cover, which are pulled up perpendicular to the cover with a tripod. Not to
mention that the roof cover will be weakened by this test because the cover is cut around the plywood prior to the pull.
