A roof is one of those things you don’t really pay attention to until something goes wrong with it. This makes choosing the right roof a very important decision. Shakespeare may have proclaimed that “a rose is still a rose,” but a roof is not simply a roof. It is important to select the right roof, especially one that will hold its own against Mother Nature. Here are some things to consider when choosing a new or replacement roof.
Roof Types:

Roofs come in a variety of styles and textures. Each type of roof has its advantages and disadvantages. When selecting the best type of roof, you’ll want to consider several factors. Some of these include the general environment where you are and the style of construction of your home or business and the general construction style that prevails in the area. Some roofing materials can last longer if they are installed a certain way. Wood roofs, for example, can be chemically treated to increase resistance to fire damage. Basic roof types include:
Asphalt
This is the most common type of roof. Asphalt shingles come in a variety of styles with different levels of durability. If you live in especially windy or cold climates, asphalt tends to wear quicker.

Metal
This is a popular choice because metal roofs are highly fire resistant. This is the roof material to choose if you are going for affordability and durability. Steel is the most common metal selected.
Wood
This type of roof is easy to match to almost any home style, making it a popular choice in many communities. Cedar is the most common type of wood used. Special treatments can made a wood roof resistant to rotting and increase the level of fire resistance.
Eco Roofing
This type of roofing is usually made from soil and vegetation. This is a better choice for warmer climates. Eco roofing may also include roofs made from recycled materials. This type of roofing is designed to be as energy efficient as possible. Solar shingles are another option when looking for eco roofing choices. Solar shingles allow you power your own home, leading to an almost instant savings.
Slate
This is the most durable type of roofing, typically lasting for 100 years or more. This type of roofing is very heavy. You’ll want to confirm that you have a roof frame that can support the total weight of a slate roof.
Clay
Clay is another heavy option, but can be effective in areas prone to mold and insects. This type of roof is common in southwest regions of the United States, but can work in most locations.

Before making your final decision, there are a few other things to take into consideration when choosing a roof. Whatever choice you make, you likely want a roof that will be durable and match the general style of your home. Some questions to ask:
How long will it last?
The average shingle roof lasts about 17-19 years, according to asphalt roofing industry standards. Some types of roofing will last from 10-15 years, while a well-maintained slate roof can last for about 100 years or so. Asphalt is the most common roofing material, making up about 80% of all roofs installed today. Laminated asphalt will last about 25-30 years. Coated steel roofs last about 40-50 years. Specially treated wood roofs, cedar in particular, can last about 15-20 years. Concrete or clay tile will last about 50 years with proper care.
Is it too heavy for your roof framing?
Clay tile, concrete and slate roofs are highly durable, but tend to be very heavy in volume. You want to make sure the framing for your roof is strong enough to support the weight of the roofing material you plan to use. If you have your heart set on a slate roof, for example, have the roof framing inspected to make sure it can hold up this type of roof.
Does the look complement the style of your home?
You made love a certain type of roof, but it won’t really add anything to your home if it doesn’t match the overall style of your home. Consider the age of your home. Older or historic homes tend to have a more limited selection when it comes to roofing materials.

Is the roofing material permitted under local building codes?
Some areas have building codes specific to the roofing materials permitting in local neighborhoods. The idea is uphold property values and set basic standards. Conversely, some historic neighborhoods may prohibit newer types of roofing in order to retain historic status.
How much does it cost?
The deciding factor on the roof you choose is the total cost. Clay, slate and wood are the most expensive roofing types. Asphalt, metal and plastic polymer are the least expensive roofing selections. Going by cost per square foot, slate roofs will set you back the most at nearly $2,000 per sq./ft. Asphalt remains the cheapest choice at $75-$100 per sq./ft., explaining why it is a popular choice.
If you want a roof that will last, you may opt to spend a little bit more since you won’t have to replace your roof for many years. If you live in a mostly pleasant climate, you’ll have a wide selection of materials that will last longer. If you live in a harsh climate, you’ll want to consider durability above cost. Proper installation is key to the success of any type of roofing. If you are not experienced with roof installation, it is best to hire a professional. Ultimately, you have to decide what your priorities are and then select a material that meets your needs.
