Maintenance Neglect

 

Maintenance Neglect

When a roof is not maintained properly, great damage will occur causing the life span of the roof to be reduced.

Debris clogs up drains; ponding water wears out low areas and weakens the roofing membrane. Chemicals attack the roof from the various sources; air-conditioning units, swamp coolers and roof top equipment.

Heavy foot traffic to maintain roof top equipment, grease, improperly installed equipment all damage the roof. Neglect can hastily speed up the process for roof failure.

Expansion & Contraction (thermal shock)

Expansion & Contraction (thermal shock)

Roofs expand and contract every day. The sun’s heat makes the roof stretch out in the day. At night, the evening cools the roof causing it to contract. This is referred to as thermal shock. Flashings and drains are typically metal penetrations that go through the roof. They expand and cool much quicker than the roof membrane. Over time, the tremendous strain from the thermal shock causes metal drains and flashings to pull away from the roof assembly at these critical areas. The movement also causes the roof to split.

Heat

Heat accelerates the breakdown process. The damage done from the UV rays is greatly speeded up when the weather is hot. A typical capsheet roof gets up to 160º on a hot summer day when the air temperature is 90º. Over time the roof looses flexibility and becomes weak.

 

Ultra Violet Radiation

 Ultra Violet Radiation

As soon as a roof is installed the sun begins to deteriorate the material. Every single day (even cool and cloudy days) the UV rays from the sun damage and break down the roof. Under the exposure of UV rays of the sun, free molecules of oxygen mix with heated hydrocarbons in asphalt and deterioration begins. 

Molecular breakdown by the sun dries out the oils in the roof. The roofing material becomes dry and brittle. Eventually it looses its waterproofing qualities.

Why Roofs Wear Out

 

Like most things in life, a commercial roof will get old and  eventually need to be replaced or restored. There are many reasons for this, here are the four main reasons:

1. Ultraviolet Radiation (UV Rays)

2. Heat

3. Expansion & Contraction

4. Maintenance Neglect

  

Restore Your Roof

Like most things in life, your roof will get old, very tired and eventually need to be replaced. This process is messy. It involves removing the entire roof down to the bear bones and basically rebuilding it. It not only takes (a lot) more time it costs nearly triple the price!

How would you feel if you could restore your existing roof (for a fraction of the price) without having to completely remove it? 

For most of our customers roof restoration is the best option. Find out why our customers want to have Century Roofing restore their roof.
