The Durability of a 30 Year Roof


Replacing roofing material is a decision best left to professional roofers. A 30 year roof may refer to one that is installed over existing roofing materials or it may be a complete “tear off” of the existing roof.

How long a 30 year roof lasts depends on the type of roofing material. This is a good reason to know the options available that include:

  • Asphalt
  • Metal
  • Wood
  • Vinyl clad aluminum
  • Slate

Asphalt shingles are the top choice for roofing material because it lasts 15 to 30 years and is the most economical. This assumes normal climate and weather events.

Wooden shingles or shakes last from 30 to 50 years. Metal roofing will last 30 to 50 years and is slightly more expensive. Vinyl clad aluminum roofing is energy efficient and lasts from 20 to 30 years. Slate shingles last the longest from 50 to 100 years and are the most costly.


Factors That Determine How Long a 30 Year Roof Will Last


There are several factors that determine how long a 30 year roof of asphalt will last. These include radical changes in temperature from extreme cold to hot sun for long periods of time.

In most cases, a professional roofing contractor will guarantee a roof for 30 years. However, it should be inspected once every five years to ensure weather and temperature are not causing unusual loss of material integrity. This is especially true in areas where high winds, torrential rains, heavy snows or hail occurs regularly.

It is also important to have a roof inspected to prevent damage by squirrels, raccoons and mice. These are animals with extraordinarily strong teeth who chew through roofing material deeply enough to cause sufficient damage.

This happens most often in areas near wooded areas where these animals are most likely to seek refuse in a warm place when the weather is cold or they need a nesting place for their young.


Cost Vs. Durability

In terms of choosing the best roofing materials, it is important to know costs vs. durability. Be sure to read and understand a 30 year roofing warranty. A warranty should cover roofing materials for up to 30 years.


A 30 Year Roofing Warranty

There may also be a roofing workmanship warranty. This is provided by the roofing contractor and covers completion of roofing installation as well as responsibility for labor and material issues should one arise. This may also include replacement or repairs should roofing materials be defective.
