Types Of Roof Membranes For Flat Or Low

Flat roof membranes are used in both residential and commercial roofing projects. In residential, it is used predominantly for large apartment buildings, garage roofs, and small extensions. It is also increasingly used for larger main roofs in single-family housing with modern designs that integrate flat roofs.

Most large commercial projects such as apartments, warehouses, sports facilities, schools, and hotels utilize membrane roofing on flat roofs. Most of these commercial buildings require roof access for mechanical systems or they have occupied roof terraces, making membrane roofs an ideal cost effective solution.

The two most common types of flat roof membranes are EPDM and PVC. While modified bitumen is also still used, most owners are moving away from asphalt based products due to the environmental and health hazards.

Rubber Membrane Flat Roof

This roofing material is a single-ply membrane consisting of rubber. Its either glued down or anchored with fasteners or rocks. If rocks are used to secure the rubber, it will have a similar look to a build up roof. But instead of gravel, the membrane will be held down by much larger stones.

EPDM roofing can come in black or white. Its considered the cheapest of all the roofing options to install as well as to repair. Installation is typically a quick and easy job. Usually, rubber roofing lasts about 25 to 30 years. If you live in a cold climate, its best to go with the white option as the black roofing material can draw in heat and end up costing you in cooling costs.

A type of hip roof with no gables or vertical sides, pyramid roofs are usually used for smaller homes like cabins and bungalows, or sheds, garages, or other outbuildings.

Pyramid roofs are popular in hurricane or windstorm prone areas, since they are extremely wind resistant.

They also provide good ventilation and extra storage or attic space, or the interior can be left open for a high ceiling.

The overhanging eaves of a pyramid roof help to improve energy efficiency as well.

Note that pyramid roofs may be costlier to construct and maintain due to the complexity of the roof design, but they do provide the aforementioned advantages.

They can be crafted from nearly any common roofing material including asphalt shingles, composite shingles, metal shingles, slate, clay or concrete tiles, or wooden shingles or shakes.

What Is A Membrane Roof

Membrane Roofing is a roof system that creates a continuous watertight covering to protect the interior of a building. Membrane roofs are predominately used as a flat roofing system since they are watertight, which is critical where water is not shed immediately. They can also be used on very low pitched roofs where shingled, slate, or tiled roofing would not perform.

A variety of materials can be used to construct membrane roofs, for example synthetic rubber, thermoplastic , liquid polyurethane, or modified bitumen can all be used. However, the essentials of a membrane roof include weatherproofing components, reinforcement, and surfacing. Sometimes a single material performs multiple essential tasks.

Below the main roofing layers are the substructure , insulation, plywood, underlays, vapor barriers, etc.

    Benefits Of A Flat Roof

    Flat roofing offers a few perks that the commercial building owner could greatly benefit from.

    First off, the cost of flat roofing is significantly more affordable compared to a traditional sloped roof. This is mainly due to the fact that the materials are generally cheaper. Theres also less risk and labor involved in the installation process for the contractor. Additionally, theyre less costly down the line as repair complications dont tend to crop up as quickly as in a sloped roof.

    Another benefit of flat roofing is the potential for added usable space. If you have easy access to the roof, you can turn the space into an outdoor space or lounge. You might consider creating a patio or perhaps even a garden. Multi-family properties are the most common places to get creative with these types of roofs.

    Another upside to flat roofing is the quick installation time. There is no need to reschedule your whole life around a roof replacement. Flat roofing usually takes no more than two days. But do keep in mind that this will vary depending on the roofing material you choose and the overall size of the roof.

    A final benefit of flat roofing is straightforward, easy maintenance. As we touched on, flat roofs dont need repairs often. And when they do, it typically wont be too much of a headache to take care of. Their flat surface lends well to frequent inspections so you can get on top of problems promptly.

    What Is A Hip Roof

    Hip roofs or hipped roofs are perhaps the second most common type of roof after gable roofs.

    What is the difference between a hip vs gable roof?

    Hip roofs are composed of slopes on four sides that come together to make a ridge at the top, while gabled roofs have two sides.

    This variance makes hip roofs even more ideal for snowy and icy areas, since the slopes allow precipitation to run off the roof easily.

    Hip roofs are also considered to be more stable than gable roofs due to the inward pitch on all four sides coming together.

    Hip roofs also provide more shade than gable roofs since there is an overhanging eave on all four sides.

    Hip roofs often include design elements like front gables to highlight a porch or entryway, or dormers or crows nests to add extra storage or living space underneath the roof.

    They can be crafted from most standard roofing materials like asphalt shingles, standing seam metal or metal tiles, or clay or concrete tiles.

    While hip-style roofs tend to be more expensive than gable roofs due to their more complicated design, they are still fairly common due to their versatility and durability.

    After all, hip roof framing and overall builds require more materials and more expertise to construct, but you do end up with more stability and storage and living space underneath the roof.

    And of course, regular care, inspections, and maintenance are required to keep your hip roof in the best possible condition.
