Roof Repair Materials

• EPDM, aka Rubber

A popular synthetic rubber roofing membrane is known for its durability and flexibility. Made from ethylene, propylene, and diene, it is resistant to UV rays, ozone, and chemicals. With a lifespan of up to 50 years, EPDM is a single-ply membrane that is relatively easy to install and repair.

• Modified bitumen

Asphalt roofing is made with a blend of asphalt, polymers, and other modifiers. It is more flexible and durable than traditional asphalt roofing and is available in various colors. Modified bitumen is typically installed in two or three layers and lasts up to 20 years.

• BUR (Built roofing), aka roofing tar and gravel roofing

A traditional type of roofing made with multiple layers of asphalt and roofing felt. The top layer is typically covered with gravel or slag. BUR is a very durable roofing system lasting up to 30 years. However, it is also the most expensive and difficult to install of the roofing materials listed here.

• TPO Roofing

A single-ply roofing membrane made from a blend of polypropylene and ethylene. It is white or light gray and is highly reflective of UV rays. TPO is resistant to chemicals and oils and can last up to 20 years. It is also relatively easy to install and repair.

• PVC Roofing

Another type of single-ply roofing membrane. It is similar to TPO but is slightly less flexible. PVC is available in various colors and is resistant to chemicals and fire. It can last for up to 20 years. However, PVC is less environmentally friendly than TPO and can be more difficult to install.

What Causes A Flat Roof Leak?

Multiple factors contribute to flat roof leaks, and understanding these can be key to prevention and timely repairs. Firstly, age is a significant factor, as materials break down over time, increasing the likelihood of leaks. A flat roof in Los Angeles is particularly susceptible to damage from intense UV rays, which can cause roofing materials to deteriorate more quickly than in less sunny climates.

Poor installation and workmanship can also leave your roof vulnerable to water infiltration. For example, water can seep through these weak points if the roofing material is not properly sealed at joints or around protrusions, such as vents or air conditioning units.

Water pooling is another common culprit, often resulting from inadequate drainage. In Los Angeles, even though heavy rains are infrequent in Los Angeles, they can lead to significant standing water that cannot evaporate quickly under the persistent sun, leading to seepage and damage over time.

Lastly, debris and structural damage, such as punctures from foot traffic or falling branches, can compromise the integrity of a flat roof, allowing water to enter. Regular inspections and maintenance can identify and rectify such issues before they escalate into major leaks.

When exploring options to repair flat roof in Los Angeles, homeowners and property managers have several approaches to consider depending on the type and severity of the damage.

Patching with compatible roofing material is often sufficient for minor punctures or tears. However, a more comprehensive approach might be necessary if the roof has extensive damage or is nearing the end of its service life.

A complete roof replacement could be the most cost-effective long-term solution in cases of significant deterioration. If the structural integrity is still intact, a roof coating or overlay can extend the life of the roof without the need for a total replacement.
