How Much Does It Cost to Replace or Install a Roof?

Your roof is one of the most vital components of your home. It protects you from the elements, provides structural support, and helps to keep your home insulated. It’s also one of the most expensive parts of your entire house. However, your total cost can vary based on a wide range of factors. Whether you’re replacing an existing roof or installing a new one, here’s a look at what you can expect. 

Average Cost to Replace the Roof of Your House

The cost to replace a roof varies greatly from state to state. It also depends on several factors, including the size, material used, labor cost, and more.For a precise figure, you’ll want to get a few different quotes from trusted roofing companies, like American Foam Experts, to compare your options. 

Average Cost to Install a New Roof

Installing an entirely new roof can be a more labor-intensive job. As such, the price may be higher than simply refurbishing it. However, your actual price will vary based on the materials used, labor costs, your home size, and more. 

Roofing Labor Cost Per Square

Some roofers will express labor as “roofing labor cost per square foot.” Others use “roofing labor cost per square.” That refers to your price per 100 square feet. You may also come across some contractors who charge by the hour. 

Factors That Affect the Cost to Replace or Install a Roof

Several factors play a role in what you’ll pay to replace or install a roof. They include:

Your Home Size

Generally speaking, the cost to repair or replace a roof on a larger house will be more than that of a smaller one. However, other factors can come into play that can make a smaller roof more expensive. 


Steep roofs are more dangerous, and they tend to be more complex. Flat roofs, on the other hand, are much safer. They’re easier to work on and require fewer materials, too. 

Flat roofs have a few additional benefits, too. They’re more versatile (have you ever wanted a rooftop garden or patio?), more energy-efficient, and more accessible.  


Your roofing materials are also going to play a substantial role in your overall replacement or installation cost. Asphalt shingles are one of the most affordable options, while tile and slate can be more expensive. 

If you’re looking at your flat roof options, a built-up roof tends to be the cheapest, while a rubber membrane (EPDM) is more expensive. Alternatively, you could choose a spray foam (SPF) roof. While it may cost more than some other flat roof materials initially, it can save you money in the long run. 

The closed-cell spray has no seams or openings, making it more water-resistant. It helps to insulate your home, which can reduce energy costs. And, if your original roof is still in decent shape, you may not need to have it removed before installing an SPF roof.  

A Quality Roof Is an Investment

As an integral part of your home, a high-quality roof matters. Replacing it or installing a new one is an investment in your family’s comfort and safety, as well as the protection of your home overall. 

If you’re looking for a more affordable yet still durable flat roofing solution that will last longer and save you money in the long run, an SPF roof may be the right choice. For more information and to receive your free quote, contact American Foam Experts today.
