The 5 Common Reasons Why Your Roof Deteriorates Over Time

It’s no surprise that as time goes by your roofing system will deteriorate. Like every part of your home, wear and tear can eventually cause a residential roof to give out and make repairs or replacements necessary. However, claiming that there’s only one reason for roof deterioration is a bit off the mark; there are more than one reason as to why your roofing system will deteriorate.

1. UV Radiation – Once your roofing system is installed, the sun can start the deterioration process immediately as ultraviolet (UV) rays can damage and break your roof down. This is due to a combination of UV rays and oxygen molecules mixed with heated hydrocarbons from the asphalt. Molecular breakdown can also cause your roofing materials to be dry and brittle, and eventually lose their waterproofing properties.

2. Thermal Shock – Thermal shock is when your roof expands and contractors every day. During the day, the heat of the sun can cause it to stretch out while the evening cools the roof down and causes it to contract. Over time, the strain from the thermal shock can cause your roof to split and deteriorate.

3. Neglected Maintenance – Another reason why your roof deteriorated enough to warrant a roof repair is due to maintenance neglect. Regular maintenance is often required to keep your roofing system in top shape, and, without it, your roof’s lifespan will be greatly reduced.

4. Debris – If your property has a tree with overgrown branches, it could become a cause for the gradual deterioration of your roofing system. If left unaddressed, a strong storm can easily cause it to fall on your roof and cause damage. Any clog in your gutters can also cause the roofing system to retain moisture and cause it to seep into your roofing material, which can result in rot and other types of damage.

5. Improper Attic Ventilation – A poorly ventilated attic can reach temperatures of 150 degrees, which spells out bad news for your roofing system. The attic heat combined with the sun’s heat can accelerate the deterioration of your roof and may even cause you to require a premature roof replacement.
