Flat Roofs

Flat roofs aren’t too common these days, as a majority of new homes are built with a decent slope. Flat roofs aren’t entirely flat, with a slope of a ¼ inch to a ½ inch per foot, they might as well be. They do not shed water nearly so easily as their sloped counterparts, so they need to be able to handle a bit of standing water without leaking.

Flat Roofs

There are three main kinds of flat roofs available on the market:

Membrane Roofing (Also Called Single Ply or EPDM Roofing)

Membrane roofing is the most common type of flat roofing material. There are a number of options, including PVC and Neoprene, but the most common material is called EPDM (Ethylene Propylene Diene Monomer). Made of recycled rubber, EPDM is an environmentally friendly material and also helps to insulate the upper-most level of your home, such as an attic. This can help to reduce the cost of temperature control.

EPDM is also waterproof and repairs to the material are relatively simple, though initial installation is rather difficult. Rubber roofing can be difficult when surrounding exterior roof features such as chimneys and air conditioning units. It is lightweight and tends to be fairly durable in most climates, lasting thirty to fifty years on average. Membrane roofing materials come in a variety of colors and textures, which makes it amenable to a wide range of home styles.

Built-Up Roofing (BUR)

For many years, built-up roofing was the only sort of flat roof available. Built-up roofing uses a combination of gravel and tar, something like a refined version of road asphalt, to create a waterproof layer over the roof. Built-up roofing is an impressively long lasting roofing material, regularly making it ten to fifteen years without any trouble, and offers a high resistance to impact and damage. Forming a thick layer of coverage over a flat roof deck, it brings a pleasing aesthetic as well.

There is a range of built-up roofing types, including smooth asphalt build-up, cold build-up, and ballasted asphalt build up, that are available to meet your aesthetic and structural needs. These roofs all offer excellent water protection and shield your home from harmful UV rays.

Flat Roofs

A low level of maintenance means that you won’t have to think about your roof for years on end—and that’s the sort of roof that you want. When the time does come to repair or replace your built-up roofing, it’s no trouble at all to remove layers and patch different areas. Most people who choose another roofing option cite the installation process of built-up roofing as their main reason. With numerous materials involved, it can take some time to put into place. Roof beams often have to be strengthened beneath this heavy material, and there are potentially hazardous fumes and vapors released during the initial installation.

Modified Bitumen Roofing

In the early 1960s, modified bitumen roofing came on the scene as an alternative to built-up roofs. It offered the same protection of the built-up roof, without the same hassle at installation. This material can create a near-seamless roofing cover when applied in overlapping layers and is much less complex than built-up roofing to install. Its polymer layer offers flexibility at low temperatures, making this material safe from cracking.

There are also a number of different ways to apply this material, including heat, torch, cold and self-application. Like its predecessor built-up roofing, modified bitumen roofing is also low maintenance and durable. Unlike its predecessor, it is also recyclable, making it a more environmentally friendly option. It is somewhat difficult to install and can be prone to leaks when installed incorrectly, so you will want to make sure that your contractor is very careful with all modified bitumen roofing seams.

The Bottom Line

No matter which one of these materials you decide to install on your flat roof, you are sure to be pleased with both its appearance and its longevity. The different material options offer you a range of styles and colors to chose from, and each material has unique items to recommend it. Our team here at Calgary Roofing is more than glad to discuss all of these options with you to help you select the best material for your home or business.

Our testimonials

"Quick installation for historic home at sound investment"

We have an old, historic home that was built before the turn of the century. It is a good house with solid bones but has needed a lot of work over the years. I knew that we needed a new roof and that I wanted to make a sound investment that also preserved the historic appearance of the home.

I called up Calgary Siding and talked with them about the different options. They sent a contractor out to my house and took a look at the different colors and the building style before making a recommendation. I did some of my own research and found that the product they had recommended had an excellent reputation and would match well with the appearance of our home.

We set up a day for the very next week when they could come out and start the process. Our old roof was gone and our new roof installed within just a few days. It all looks beautiful and we haven’t had a bit of trouble with it at all.

"Excellent job! Impressed with the customer service"

My family and I decided to build our new home from scratch. It has always been a dream of ours to create something unique and beautiful and perfect for our family of six. Throughout the process, I got a pretty good handle on the construction business and worked with a lot of different experts and contractors.

I was so impressed with the customer service that I received from everyone that I talked to. They were always happy to answer my questions—and I sure had a lot of them! The roof was really important to me because it felt like the thing that would best protect our investment in this new home, standing between us and the weather.

We went over all of our options and decided on a tile roof to match the style of the house. They were at our house and working away in no time, and they did an excellent job!

"Happy with the match of roofing material and color"

My house has a metal roof and I love it. One of the only issues with a metal roof is the fact that it can be rather difficult to repair. When one of our panels got a sizeable dent, I was pretty worried that we wouldn’t be able to repair it without it being quite obvious.

I called up the company and expressed my concerns about the roof and asked whether or not they would be able to match the color of our existing roofing panels. They sent one of their contractors out to my house to take a look. He brought some samples with him and we compared them to the material that was already on the roof of my home.

The fourth or fifth metal that he brought was a near-perfect match and I was so relieved. The very next day he was back with a couple of guys and they replaced the dented panel. It was a bit shinier than the rest at first, but now you can’t even tell!

"Pleased with customer service and fair pricing"

Everyone that I met from the company was kind and courteous, and our team of roofers got the job done quickly. My new roof looks beautiful! My wife and I bought a fixer-upper that hadn’t gotten a new roof in far too long, and I was worried that parts of the wood beneath the shingles would be too far gone. The team ripped off the old roofing in no time and then consulted with the two of us.

There were some boards that had to be replaced, but it wasn’t nearly as bad as I had feared. We agreed on a new method and went right on ahead. They were very fair in their pricing for the additional trouble of replacing the wood, and I was quite pleased with their customer service throughout. They are a great team of locals and I really recommend them.
