If you want to replace your garage's old asphalt shingles with a synthetic rubber roofing membrane, but you're not sure if the new roofing system will protect your garage, keep reading. A synthetic rubber roofing membrane, or EPDM, comes with numerous features that allow it to ward off water and heat damage. In addition, the roofing material is durable enough to resist cosmetic problems, such as scuffing and tears, and comes with colored acrylic coatings that extend the membrane's life. Here are some reasons to install a rubber roof on your garage.

Protects Your Garage From Water Damage

Once asphalt roofing shingles reach the end of their lifespans, they can experience a number of problems, including water damage. Old asphalt shingles can become loose, lift up and allow water to penetrate the garage's roof deck over time. Eventually, the roof deck's wooden frame deteriorates and rots, which places your garage at risk for structural failure.

Ponding water is another issue you might have with your garage's shingles. Ponding describes rainwater that forms puddles of water in different areas on the roof. The puddles remain in place until the sun evaporates them, which can take days to happen. Even if you place gravel or another absorbent material on the ponding water to soak it up, it may not be enough to protect the roof. In some cases, you may make the problems worse if the puddling water absorbs into the shingles.

Sometimes, shingles curl or cup when they become old and worn or when water accumulates beneath them. The corners and sides of the shingles may pull or bend upward, which makes the shingles look similar to teacups. Curling shingles can easily break when you walk on or touch them. If the weather becomes windy, the damaged shingles can actually blow off the roof, which exposes the wood deck below them. 

A synthetic rubber roofing membrane protects your garage by forming a waterproof barrier over its surface. Roofing contractors use several methods to install the membrane, including using metal fasteners, glue or ballasted gravel, rocks or stones to hold it in place. Because EPDM forms a smooth finish over the roof deck after installation, rainwater and melting snow aren't able to penetrate it.  

Now that you know how a rubber roof protects your garage from water damage, it's time learn about its heat-resistant features.

Protects the Garage From Heat Damage

Another benefit of using a rubber roof is the prevention of heat damage. Some older asphalt roofs experience a problem called blistering, which develops when moisture travels beneath shingles, mixes with heat and forms gas-filled bubbles of different sizes. As the sun's heat penetrates the bubbles, they become hot enough to burst open, which exposes the roof deck to the elements. An EPDM roofing system doesn't allow blistering to occur because it's virtually resistant to heat, including the sun's UV rays.

Rubber roofing comes with a colored acrylic coating that keeps the roof and garage cool in the summer. If the garage attaches directly to the home, it can allow heat to enter the room and travel to the rest of the house, which may increase your energy expenses over time.

In addition, the coating helps the membrane maintain its shape and integrity when exposed to sunlight and heat. When exposed to excessive heat changes, old asphalt shingles can potentially crack, flake and split. If the garage's shingles already show signs of heat damage, it's essential that you switch to a rubber roof to prevent additional problems with the garage.
