Roofing Types

Choose your Roofing

There are many types of roofing materials to choose from, including asphalt composite shingles, metal shingles, wood shakes, and clay tile. Rather than simply going with the option you previously had, you might want to consider a longer-lasting or more modern roofing material. Choosing the right type of roofing requires that you weigh appearance, longevity, roofing material prices, and structural issues. 

Here are different types of roofing materials to consider when it comes time to replace your roof.

Metal Shingles/Shakes

For homeowners who do not like the look of standing seam metal roofs but want the advantages of metal, there are steel or aluminum shingles or shakes available. 

Made from stamped metal and finished with either a high-quality baked-on coating or mineral granules, metal shingles can be fabricated to look very much like traditional asphalt shingles, wooden shakes, or even slate or clay tiles. 

They are an excellent choice where appearance is a critical concern but you still want a durable and long-lasting roofing material. Metal shingles and shakes can last 30 to 50 years.


Asphalt Composite Shingles

The fiberglass asphalt shingles are a fairly lightweight but also durable roofing material. The organic asphalt shingles are heavier but still durable. Composite shingles excel at flexing and adapting to a roof's movements due to expansion and contraction. 

They typically come with a 20- to 30-year warranty, and replacing individual shingles that are damaged is a fairly easy job. Plus, virtually every roofing company is familiar with installing these singles. Depending on the quality of the shingles and the conditions, the lifespan of the roof can range from 12 to 30 years.




Wood Shingles/Shakes

Wood roofs are very attractive, but they are also quite expensive and have limitations. They are not as long-lived as some other roofing materials, and they are a poor choice in areas that get lots of moisture or where wildfires are a danger. Still, they are among the most attractive roofing materials, which makes them a popular choice for luxury homes. 

Longevity depends on circumstances and maintenance. In relatively dry climates, a wood shingle or shake roof can last 60 years; in damp conditions, you might only get 20 to 30 years from the roof.


Membrane Roofing

Another type of roofing material for flat roofs or very low-pitch roofs is a membrane roof. There are several types of membrane that can be used, including: 

Neoprene (polychloroprene) 

EPDM (ethylene propylene diene monomer) 

PVC (polyvinyl chloride) 

Chlorinated polyethylene and chlorosulfonated polyethylene sheets 

Polymer-modified bitumens

 

 One of the best membranes is EPDM. EPDM is a synthetic roofing material often referred to as "rubber roofing." It is similar to rolled asphalt roofing in that it is applied in large sheets that limit the number of seams where water can infiltrate. The lifespan is typically 20 to 35 years or more when the roof is properly maintained.



Rolled Roofing

Rolled roofing material is the mainstay of low-slope residential roofs as well as outbuildings like shops, sheds, and other utilitarian structures. This basic type of roofing consists of long rolls of mineral-impregnated and asphalt-impregnated material topped with mineral granules. Each roll is about 100 square feet of roofing and about 3 feet wide. 

 

You can expect that rolled roofing is one of the cheapest roofing materials, but it doesn't offer much aesthetic value. The large, thin strips offer a fast and convenient way to cover a sloped-roof building like a workshop where appearances aren't important. It can be applied either with the torch-down method or with roofing nails. 

 

On average, rolled roofing lasts about 5 to 8 years before it needs to be replaced.


Metal Roofing

The most common type of metal roof is the standing seam roof—so named because the aluminum or steel roofing panels meet in raised seams that interlock to keep moisture out. Metal roofs of all kinds are increasingly popular in regions with heavy snowfall or where there is danger of wildfires, as this durable roofing material is fireproof. 

 

Metal is also a long-lasting type of roof, and it's recyclable when it finally does wear out, however installation requires special skills, and not every roofing company is prepared to install a standing seam metal roof. 

 

Metal roofs commonly last 30 to 50 years, but some have been known to last 75 years.
