If your commercial property has a flat roof, you probably know what a nightmare these roofs can be without proper protection. With the wrong installation, maintenance, or drainage, you may find yourself fixing leak after leak, even after the slightest bit of rain. Not only is this a threat to your roof system, but it may even void your warranty, making it impossible to get affordable repairs!
That’s where a membrane roof comes in. These innovative modern roofs help keep water intrusion at bay. Because they come in various options and styles, it’s easy to find one that fits your budget, needs, and the look of your building.
If you’re ready to get rid of water issues for good, here’s what you need to know.
The Basics of Membrane Roofing
As their name suggests, membrane roofs create a protective membrane, or a barrier, on the surface of a roof. They may use different weatherproof materials, including synthetic rubber, thermoplastic, or liquid polyurethane. Often, this membrane is thin, but some roofs use much thicker, more built-up systems.
Membrane roofs are most often used on no- or low-slope roofs. Because they’re watertight, these surfaces are ideal when a roofing system isn’t pitched enough to displace water quickly. With a membrane roof, you can be sure that any pooling water won’t seep into the building below.
You can often find membrane roofs on flat-topped commercial buildings. However, they’re also common on flat residential roofs and patio covers.
Types of Membrane Roofing
As mentioned above, there are several different options for membrane roofing. Below are some of the most common:
Thermoset Membranes
These membranes use synthetic rubber. These types of roofs are adhered or mechanically attached to the building. High-performing thermoset membranes are freeze-, thaw-, and fire-resistant.
The most common materials for thermoset membranes are neoprene and ethylene propylene diene terpolymer (EPDM) roofing.
These roof membranes are often black, which may lower your building’s energy efficiency. However, you may be able to find white styles or other “cool roof” options to reflect light and heat better.
Thermoplastic Membranes
These durable and versatile membranes are often heat-welded to your roofing system. This creates a stronger bond than thermoset membranes, meaning these roofs need less upkeep.
The most common materials for these membranes are thermoplastic olefin (TPO) roofing and polyvinyl chloride (PVC) roofing.
TPO roofing is the more affordable option, often using a single-ply membrane. Its heat-resistant and reflective nature helps cut down on AC costs. The typical lifespan is around 15-20 years.
PVC roofing is heat-, chemical-, fire-, and puncture-resistant, lasting up to 30 years. This durability comes at an added expense, but you may enjoy less maintenance and fewer repairs.
Modified Bitumen
To create modified bitumen membranes, manufacturers add rubbers or plastics to heated bitumen to enhance this material’s flexibility, often with fiberglass reinforcements. Modified bitumen usually requires a torch application or cold adhesive.
Membrane Roof Benefits
Membrane roofs offer several advantages for commercial property owners. Regardless of the roofing material you choose, you’ll get the following benefits:
Prevents Water Damage
The most obvious benefit is the waterproofing. Thanks to their strong-seamed or seamless design, membrane roofs lower the risk of water intrusion. This can prevent rot, mildew, mold, and other moisture issues.
Without a membrane roof, you might expose your commercial building to structural damage over time. If mold takes root, you may expose your workers and guests to hazardous symptoms.
Durability
No matter which roof option you prefer, you’ll enjoy lasting durability. Membrane roofing can withstand harsh weather events, including heavy rain and strong wind gusts.
Even extreme temperatures won’t damage your roof. Some roofing options even enhance your building’s energy efficiency by reflecting heat.
Certain materials like PVC are also chemical resistant, making them ideal for industrial settings.
Long Lifespan
Depending on the roof membrane you choose, you may enjoy a lifespan of 15-30 years. With proper maintenance, some roofing systems may last even longer. The right choice can also extend the life of your entire roofing system.
Cost Effective
Membrane roofing is often more affordable than traditional roofing.
Installation is fast and easy for these prefabricated roofs. Because they come in a single layer, you won’t have to pay extensive application costs.
You’ll also save on maintenance. Most membrane roofs need little upkeep or repairs. They’re also resistant to many types of damage that traditional roofs see, including rot and pests.
Versatility
Membrane roofs are versatile enough for any building. Most of these roofs can be tailored to fit any size or shape. For a flat roof, they can sometimes be your best or only option for proper protection!
Membrane Roof Maintenance
As we’ve mentioned above, regular maintenance is necessary for the health of your roof.
On your own, make sure to clean your roof according to the manufacturer’s recommendations. Clear the drains and remove any wind-blown debris. For certain membrane roof types, debris can damage or puncture the protective membrane.
In addition, you should perform regular visual inspections to look for punctures, exposed seams, shrinkage, or damaged flashing. This is even more important after severe weather. You can often make temporary repairs with construction-grade caulk or sealant.
Get repairs and address any leaks right away! Membrane leaks can continue growing if you don’t patch the affected area.
If you want to enjoy the full lifespan of your roof, you’ll also need expert roofing inspections. A professional roofer can identify minor problems before they become expensive issues. They can also inspect the membrane’s integrity, insulation, coatings, etc.
