Two Reasons to Build an Extension for Your Home

1. Expand your home

Want to make your house bigger than before? Whether you plan to grow a family or accommodate more furniture, building a roof extension is a good idea. If you’ll use the space beneath the roof as a living quarter, be sure to make it comfortable.

2. More practical than buying a bigger property

It’s more convenient and less stressful to get a roof extension rather than move to a bigger home, wouldn’t you agree?

Instead of getting a new property, build an extension. Planning a new home is a stressful experience. Not to mention, it’ll cost you a lot of money. With a flat roof extension design, you wouldn’t need to move out. It’s also one of the best ways to increase property value.

Benefits of Using a Flat Roof for an Extension

1. You can also utilize the space above

Constructing a pitched roof extension design will never allow you to maximize space. A flat roof makes an amazing choice. Why? You can use the space on top for a rooftop garden if you want to grow vegetables or small attractive plants. A game room or relaxation space would be nice, too!

2. Cheaper and easier to build

Property owners are drawn to flat roofs for their home design. One of the reasons why flat roofs are an appealing choice is that installation is fast and affordable. Contractors install one large sheet for an entire roof area. Not much structural support is required. With a sloped roof extension, contractors will have to install shingles piece by piece.

3. Matches any architectural design

Some people say that flat roofs are uninteresting because of their plain appearance. But because they match any architectural style, they make amazing options for roof extensions. Here's a picture of an ongoing flat roof extension work.

Whether you have a cabin-style house or a Colonial house, it doesn’t matter. Flat roofs complement any residential property style because it takes on a neutral appearance. However, if you have something less contemporary, it’ll certainly add a modern feel to your home.

4. Easily accessible

Anyone can walk on a flat roof without difficulty. This is especially important for maintenance and repair purposes. You may also want to opt for a parapet to serve as a barrier. Installing a parapet will add safety to your flat roof.

Different Materials for Your Flat Roof Extension

The success of your flat roof extension depends on several factors. The material is a huge one. Homeowners often end up choosing a particular material because of the cost, longevity, cooling benefits, and color options.

If you want to know what you can install, consider these flat roofing materials:

1. EPDM (Ethylene Propylene Diene Monomer)

We often think of EPDM as the perfect material for commercial flat roofs. EPDM also makes a good option for flat roof extensions because of the many benefits it offers. For one, EPDM lasts very long.

Its average service life ranges from 40-50 years (or more). Another fact is that roofing contractors install it with ease. Lastly, EPDM is can be recycled at the end of its lifespan. It’s an eco-friendly material.

2. TPO Roofing (Thermoplastic Olefin)

TPO roofs are great in that they resist algae growth and buildup of debris. Like EPDM roofs, TPO can be recycled at the end of their service life. It will also improve your home’s energy-efficiency because of its reflective properties.

Instead of absorbing the heat of the sun, TPO will block it. The result is that your home stays cooler in warmer times of the year. What’s more exciting is that TPO comes in different colors.

3. Torch Down Roofing

The installation of a modified bitumen roof requires the use of a torch. Modified bitumen is known to be a tough and resilient roofing system.

Compared with other flat roof materials, torch down roofing is the cheapest to install. A full installation costs you an average of only $3-$6 per square foot. Take note that this flat roof extension cost is an estimate. It changes depending on the material quality, manufacturer, extra features, and job complexity.

While torch down roofing systems are more affordable, they don’t last as long as EPDM. The average lifespan of a torch down roof is 20 years.

4. PVC Roofing (Polyvinyl Chloride)

PVC roofs boast of many impressive benefits. While commercial properties use them because they’re wind-resistant and fire-resistant, most homeowners choose them for flat roofs as well. Dampness and ponding water won’t wear down a PVC roof. And yes, PVC roofs help lower your cooling bills.
