30-, 40-, and 50-year Shingles

If your house has a damaged roof or one that leaks this may cost you thousands of dollars to replace. The condition of your roof is one of the most important things to be constantly aware of. If you don’t know when the roof on your house was installed, you don’t know how long your roof will last in its present condition.

You need to know what roofing materials were used on your roof, the dimensions, the method of installation in order to get a good gauge of when you may need to have it repaired or replaced.

Residential houses have roofs that are of a steeper incline compared to non-residential buildings. Commercial and industrial buildings have roofs that are more or less flat.
Understanding Roofing

There are a handful of common roofing materials you may see, like, glass, concrete, or aluminum, but the most common ones in residential houses are asphalt shingles. Slate shingles, while being the top of the line for roofing materials, is too expensive, sometimes being more expensive than the house itself. However, slate shingles can last for many generations without needing repair.
Learning The “Secrets” of Roofing

Spending twice as much for a roof is no longer a priority with modern day families. That is why asphalt is the popular choice for roofing materials today. Asphalt shingles may not last for generations, but they usually last for 50 years without needing any repair. Likewise, repair kits and patching materials for use in asphalt roofs are generally more cheaper than that of slate shingles.

Asphalt shingles generally come in three classes or step-ups: 50-, 40-, and 30-year dimensional.

The 50-year dimensional is obviously the more durable and more expensive of the three grades. Aside from the difference in the durability of the different dimensions of the three grades, there is the aesthetic difference or the looks. A 50-year dimension gives a more elegant look compared to a 30- or 40-year dimension.

A 30-year shingle that is correctly installed will last about 25 years without any need of major repair. Though they are not made with the same thickness as the 40- or 50-year dimensions.

A 40-year shingle will give you 30 years of good use before needing any major repair or replacement. Because the 40-year shingle contains about 70% more asphalt than the 30-year shingle, it becomes more practical to use in the long run.

The 50-year shingle gives you the same degree of durability than the 40-year shingle, about 30 years. The only advantage of having more asphalt in the 50-year shingle is that it looks more prestigious than the 40-year shingle.
