Flat Roof Replacement


Deciding that it’s finally time to undergo your flat roof replacement project is a big decision. It’s a major commitment of time, money, energy, and human resources. It’s not a decision that many building owners like to make because there is so much weight behind it. However, it’s a decision that must be made no matter how difficult, stressful, or frustrating it can be. If you’re on the fence about whether or not it’s time for your flat roof replacement, this post will help you make the best decision for your building.

Do You Need a Flat Roof Replacement?

Perhaps the most difficult part in deciding to replace your flat roof is deciding whether or not you truly need a flat roof replacement. It’s very hard to know whether or not your roof needs to be replaced, if you can get by with just some repairs, or if there might be a better option out there. So how do you know if and when you need a flat roof replacement?

Sometimes you need to replace your roof, and you just know that you need to. Some roof problems are obvious.

Repairs are Getting Out of Hand

If you find yourself making constant repairs on your roof and you don’t feel like they are worth the money you are putting in to them, that can often be a sign that the roof has reached its limit and should be replaced.

Structural Concerns

Is your roof no longer as structurally sound as it once was? If your roof is in bad shape and is a danger to those in and around your building, then you’ll certainly want to consider a flat roof replacement to ensure safety in your building.

Can You Use a Roof Coating?

A great alternative to a flat roof replacement project is a roof coating to restore your existing roof. If your roof is still in structural condition, it is oftentimes a great alternative to apply a roof coating and simply extend the life of your roof without replacing it. You can receive a new warranty with a roof coating, without having to replace your roof.

Best Roof Replacement Material

There are many different roofing materials available, and it can be overwhelming to choose the right one for your building. We have covered many different features of the most common roofing materials elsewhere on this blog, such as installation, insulation, weather resistance, and other features. Give those posts a read to see which material you might prefer on your building.

In addition to researching the materials, it is also important to research which roofing contractor you use on your flat roof replacement project. A good contractor will recommend to you the material that will serve you best, which is exactly what you want.

Flat Roof Replacement Process

Traditionally, replacing your flat roof means you have to tear out your existing roof and then install an entirely new system in its place. This is a very long process that takes a significant amount of man hours and money to complete. Avoiding the tear out and replacement process, either through repairs, installing a second roof, installing a roof coating, is almost always preferable to flat roof replacement.

Retrofit Roofing Systems

There are some roofing systems that can be installed directly over top of the existing roof. A roof coating and a spray foam roof are two examples of retrofit roofing systems. As long as your existing roof is in good structural condition, a spray foam roof or roof coating can renew and restore your existing roof and avoid tear off and replacement.


Flat roof replacement is a major project that should be heavily researched before a decision is made, especially if you’ve never replaced a commercial roof before.
