Victorian-style steep roofs are so out of date. Low-pitched roofs became the new standard when it comes to contemporary houses because they are very charming and because they cut energy costs on the other hand.
Low-slope roofs make sure the heat stays within your home during winter and also prevent hot air from creeping in during summer. Also, you get more space to experiment with in the attic.
On the downside, water drainage poses the biggest issue here since water can’t roll off the roof easily. Water pooling can cause leaks, degrade roofing materials, and damage the roof structure long-term. The key to avoiding low-slope roofing problems is in the materials used. Thus, today we are going to talk more about low-pitch roofing options and materials that will make your roof not only good-looking but long-lasting as well.
6 Most Popular Low-Pitch Roofing Materials
1. Rolled Roofing
Asphalt rolls (rolled roofing) provide a temporary solution for low-pitch roofs (when we say temporary, think about 5 to 8 years maximum). Oil-based asphalt comes in a plethora of textures, styles, and colours. Yet, although quite attractive and easy to install, rolled roofing is not an ideal option for low-pitch roofing, except for sheds and garages.
2. Standing Seam Metal Roofing
Standing seam metal low-pitch roofing ensures the best protection against weather elements (rain in the first place). Unlike corrugated metal roofing, screws don’t penetrate standing seam metal roofing and concealed fasteners are used for installing and attaching metal sheets. If you live in an extreme weather climate and are looking for an option that provides the ultimate weather-tightness, a double-lock system could be a decent choice.
3. Modified Bitumen
Single-ply materials are most commonly used with low-pitch roofs. Modified bitumen is one of these materials, also known as mod bit, or APR (atactic polypropylene). It has proven to provide superior protection against water pooling whilst still being less costly compared to plastic or rubber solutions and it also comes in a wide range of colours. Similarly to asphalt rolls, mod bid requires more frequent re-installs.
4. Built-Up Roofing
Built-up roofing or BUR can last for over 100 years. Not only is this low-pitch roofing system very durable but hail has no chance against it either. The reason behind this is that this type of roofing consists of multiple layers – reinforced felt, hot liquid asphalt, and pea gravel that make it resistant to elements such as water, UV rays, etc. Compared to the above-mentioned single-ply materials, built-up roofing is a much better option for large low-slope roof surfaces.
5. EPDM Roofings
EPDM or ethylene propylene diene terpolymer is basically modified rubber. This material truly makes a great choice for low-pitch roofs since it can withstand numerous elements, including chemicals, hot and cold temperatures, winds, hail, and water. Although it is on the list of single-ply membranes, EPDM seems to be a cut above all the rest. It is available in two colours – black and white.
6. Roofing Tiles
Roof tiles make the top 3 options when it comes to low-pitch roofs simply because they give you the widest range of styles, textures, and colours whilst ticking all of the boxes when it comes to durability, protection from pooling, etc. Needless to say, tiles don’t absorb water, which is of great importance due to all of the reasons we’ve previously mentioned and they don’t degrade easily. Most roof tiles are resistant to winds, freeze-thaw cycles, high temperatures, mold, and flying debris while they are very attractive, too!
Why Is the Choice of Materials So Important?
Low-pitch roofs come with a couple of catches and obstacles. If a single element is not installed properly, it can jeopardize the entire roof structure. For instance, water can easily pass through the smallest gaps in the tiling, especially during rainfalls. That is also why individual roof components should be tested multiple times whilst the roof is being constructed.
However, if you don’t choose the right material, the one that can withstand whatever it takes and stand strong against the elements to protect your most valuable asset – your home, everything else will be in vain. Ask for professionals’ advice before making the final decision and choose a pitch roofing service only then.
