If you are planning on getting a new roof installed, you will have to find out what roofing material will match your requirements and budget. This decision can be quite confusing as there are a number of materials in the market that you can choose from. Understanding the differences between various shingles will help you make a more well-informed decision.

When it comes to choosing the right material, in addition to the aesthetics and functionality, the lifespan of the roofing becomes another factor that has to be taken into consideration. You will find manufacturers advertising that their roofing will last for 20, or 30 or 40 years (sometimes even longer). So which one should you settle for?

Things to Understand

  • Most 20-25 year shingles are 3-tab shingle types and have been in the market for a very long time. These shingles are much lighter when compared  to architectural shingles and are more prone to wind damage- they may also get ripped right off your roof in high winds
  • Most architectural shingles are available  in 3 grades and  typically a 30 year shingle will have an average lifespan  of 25 years while  the 40 & 50 year ones will last  for approximately 30 years
  • The factors you have to take into consideration are the amount of wear & tear your shingles will be taking and the kind of climate they have to face. In most  instances, roofing manufacturers  presume  you are  not going to live in a particular  house for over 30 years

The Functionality Factor

With reference to functionality, thicker shingles last longer and the 30, 40 & 50-years shingles are going to be much thicker than the 20 -year ones. A thicker shingle provides your roof more protection, looks better and you will not have to re-roof that often. There is no doubt that when a manufacturer provides a 30, 40 or 50 –year warranty for a particular product, it is going to be priced higher too. But when you are making a decision about the type of roofing you want, it’s important to be realistic.

Other Affecting Factors

Factors including sun, the climate & the installation affect the real life span of any roofing. In areas that have intense sun right round the year, you may find that even a 30 and 40 year roofing will not last beyond 20 years. Another important aspect to take into account is the number of years you plan to live in a particular a home. If you are planning to move to another location within 5-10 years, there is no reason for you to opt for a 30 or 40-year roofing material.

The Installation Matters

Having a long-lasting roof is also a lot about how the installation work has been handled. It is important that you zero-in on a reputed roofing contractor, who is certified, insured and one who will provide warranties for their work. This warranty is different from the warranty that the roofing material manufacturer offers; both are important when it comes to getting a long-lasting roof installation for your home.
