Your roof can last over 30 years.
Some flat roofs can last even longer.
Because of this, you might not have had to deal with a roof replacement before. There are a few things you should consider before you start looking for a roofing contractor.
Here’s what you need to know about flat roof replacements.
1. What Flat Roof Materials Can You Choose From?
There are several different types of flat roof material you can choose from, but it’s important to remember this material isn’t always the same as other roof types.
We’ve created a short list of the most popular options.
- Modified Bitumen Roofing
This roofing material can be made of a number of different compounds.
It’s rolled onto the roof in a single layer, and with a layer of polymer on top, it is a durable choice.
But this option does have a few downsides.
It is traditionally applied by a torch, which can produce a bad smell and create safety hazards. Make sure your roofer is experienced with this type of roofing application if you choose it.
- Built-Up Roofing
This type of roof is made of tar and gravel.
Built-up roofs are resistant to damage, good at insulating your home, and a beautiful home feature.
This is the most traditional flat roof material.
- Single-Ply Membrane Roofing
Single-ply membrane is a polymer membrane roof made of recycled rubber.
While this material is lightweight, it is also durable. You won’t have to worry about debris denting or scratching the surface.
If you’re looking for an environmentally-friendly option, this is a good choice.
- Metal Roofing
Metal has become a popular flat roof material choice in recent years.
These roofs can be made of several different types of metals, but the most common option is aluminum.
Metal roofs are much more durable than other flat roof options, but they can rust if they get and stay wet for too long.
2. How Much Do They Cost?
Before you can choose your favorite roofing material, you have to consider a few other factors, such as the cost.
If a metal roof is outside your budget, you may want to stick to something cheaper instead.
- Modified Bitumen Roofing
Modified bitumen roofing is one of the cheapest flat roof materials out there.
The cost can be as low as $3 per square foot, but it depends on who you work with. You might have to pay closer to $6 per square foot.
However, the installation process is quick and easy.
Since the professionals won’t have to spend too much time working, you’ll save money on labor costs.
- Built-Up Roofing
This roofing material is slightly more expensive than modified bitumen.
You can spend anywhere from $3.50 to $7 per square foot.
The cost of installation is also much higher than most other methods.
- Single-Ply Membrane Roofing
Again, the installation cost for single-ply membrane roofing is higher than modified bitumen roofing.
But the average price for the material is about the same, anywhere from $4 to $6 per square foot.
- Metal Roofing
This is the most expensive flat roof material.
It can cost up to $8 or even $10 per square foot. The installation can also be quite pricey.
3. How Long Do They Last?
To justify the cost of a roof replacement, you’ll want your new roof to last a long time.
Here’s a quick breakdown of each option.
- Modified Bitumen Roofing
This roofing material can last up to 30 years.
If you choose this option, you might not have to worry about replacing it again.
- Built-Up Roofing
While these roofs don’t last as long as modified bitumen roofing, they’ll stay in good shape for close to 20 years.
However, they might require a bit more maintenance.
- Single-Ply Membrane Roofing
This roofing material is extremely long-lasting.
Once you install this roof, you won’t have to worry about a replacement for another 50 years.
- Metal Roofing
A metal roof can last 35 years if you keep it in good condition.
But if it rusts, you’ll need to replace it right away.
4. Can They Withstand Heat and Cold?
A roof will only stay in good condition for 30+ years if it’s in the right environment.
Otherwise, you might end up replacing your roof again a lot sooner than you planned.
- Modified Bitumen Roofing
This roofing material can hold up in almost any weather.
Whether you live in an area that gets snow or heat waves, this roof should do fine.
- Built-Up Roofing
Built-up roofing can develop leaks and water damage over time.
Because of this, you shouldn’t have this type of roof if you live in a wet or snowy environment.
- Single-Ply Membrane Roofing
Single-ply membrane is waterproof.
This means it’s a good option for places that get a lot of rain or snow.
It also withstands heat, and it can even survive fires.
- Metal Roofing
Metal roofing reflects heat away from the structure.
Because of this, it’s a good option for hot areas.
