While sloped roofing is more abundant, it is not uncommon to see buildings and homes with flat roofing. This is especially true in drier regions that do not experience much rain. Flat leaves are known to leak more often as a result of any water not having a place to roll away. There is always a slight slope to a flat roof, but it is not as steep as with pitched roofing, and water cannot roll away as effectively.

Your Options for Flat Roof Replacement

When flat roofing gets pools of water, it can damage the materials and integrity of the roof. The top signs of a leaking roof to look for include:

  • Stained walls or ceilings from water damage
  • Bubbling paint
  • Mold or mildew on the walls or ceilings
  • Dripping water

Older roofing is more susceptible to leaks and may require replacement rather than simple repairs. If you find yourself needing to replace your flat roof, these are your options.

Metal Roofing

Metal is a highly popular choice for flat roofing replacement, specifically aluminum. Metal roofing is durable and lasts for up to 35 years with proper care and can help keep energy costs down by reflecting the sun’s heat away. You can buy metal roofing in large sheets or order smaller sizes if you have irregular-shaped roofing. Metal roofs do have a downside too. To replace them, you need to completely remove the roof, which is time-consuming. Metal roofing is also more prone to rust than other materials.

EPDM Roofing

EPDM is a synthetic rubber roofing consisting of recycled materials that are both inexpensive and durable. Many choose EPDM because it is easy to install and affordable, and it lasts a long time. Installing EPDM does require seaming which can be troublesome as it allows for more leaking opportunities as seams pull away from the roof over time. If you apply EPDM as a spray, this risk is significantly reduced.

Built-Up Roofing (BUR)

BUR consists of layers of tar and gravel and this roofing is popular because it provides efficient insulation too. The layers of BUR make the system sturdy but also heavy. If you already have BUR, then this is the same roofing you want to use again when replacing. If you have a different system, you need to confirm with a contractor that your building can support the additional weight of a built-up roof. It is also important to note that during installation, the building needs to be empty and this can be an inconvenience.

Modified Bitumen Roofing

Modified bitumen is affordable, easy to install, and is a good reflective agent. The installation involves rolling the bitumen across the roof securing it with a blowtorch. You will need an experienced roofer as this process is dangerous.

Spray-On Coating

You can also apply spray roofing to add a seal and protective layer that prevents water damage. Your choices include polyurethane foam or silicone. With sprayed-on coating, there are no seams and when added to EPDM roofing, you get additional roof longevity. These coatings can be tedious to apply but they are worth it and will increase the lifespan of your roof when properly applied.
