We will cover everything you need to know about replacing a roof - from the basics of how it works to the different types of roofs available on the market today.

Different Types of Roofs

There are different types of roofs to choose from. You can use a shingle roof, which is the standard roof on most homes; a metal roof, which is lightweight but requires an initial investment for installation and has a reputation for being long-lasting; or a concrete roofing system, which is often used as a part of new construction.

What are Roofs Made of?

Roofing materials can get expensive, and the material you choose will depend on a few factors- including durability, the level of maintenance required to keep it looking new, weight, and weather resistance. Here are the most common types of roofing materials:


Metal roofs are lightweight but require an initial investment for installation. They have a reputation for being long-lasting, resistant to fire or damage from wind and hail storms. This is the least-expensive type of roofing material.


This roof is made of clay, terracotta or wood shakes. It's lightweight, durable and renewable. The downside is that it requires lots of maintenance to keep looking fresh.

Asphalt Shingles

The least-expensive type of roofing material is asphalt composition shingles, which are made from a blend of bitumen, sand and gravel that's processed into different shapes including squares and rectangles. The advantage of asphalt composition shingles is that they're easy to install and can come in a variety of colors and textures. The downside is that they don't have much resistance to fire and will deteriorate quickly with exposure to the elements.

Should You Tear Off the Roof or Add a Second Layer?

Most people tear off the old one and install a new roof. However, this is not always the best option. It can be more expensive and time-consuming than an additional layer of roofing material on top of the existing roof.
