Understanding TPO Roofs

Crafted from thermoplastic polyolefin, TPO roofing membranes are highly durable against impacts, and all types of weather, and are resistant to cracks and tears. They are mostly used on flat roofs, but can also be used for residential roofs. Though TPO is a fairly new roofing material, here’s why it’s stealing the spotlight:

  1. Durability

Rain or shine, TPO roofs can handle it all. From scorching sun to chilly winters, it stands tall. Plus, it is mostly impenetrable and rarely tears or punctures. 

  1. Energy-Efficiency

Due to their reflectivity, TPO roofs can contribute to lower energy bills. Their surface deflects UV rays, reducing the amount of heat absorbed by the roof and keeping interiors cool.

  1. Low-Maintenance

TPO roofs are not high-maintenance; They don’t require routine painting or resealing. They are also resistant to algae and mold, reducing the need for frequent cleaning. 

  1. Cost-Effective

You don’t need to break the bank for a TPO roof. When it comes to the cost of TPO roof repair, it’s budget-friendly, similar to other single-ply roofs.

With these benefits, it is clear to see why TPO roofs are a top choice for flat roofing systems. But they are not without their drawbacks, and can show signs of aging and damage over time.

#2 Cracks 

Tiny cracks might not look like a big deal, but they’re like tiny doors for water to sneak in. Regardless if it’s the blazing sun or the chill of winter– your roof faces it all, and it might develop cracks over time. These openings allow water, debris, and pests inside the roof structure, which can lead to major damage. 

Solution: The cracks can be repaired by filling them with a sealant or adhesive.

#3 Sagging 

A sagging roof indicates water is accumulating on the surface, burdening your roof’s structure. The weight of the water can make your roof sag as the structural elements struggle to hold up the system. If there is standing water on your roof, there might be a problem with drainage.

Solution: The roof deck may need to be repaired or replaced. There might be an issue with the drainage system, check for clogs or an insufficient roof slope.

#4  Aging

Your TPO roof might be durable, but it is still susceptible to signs of aging over the years. As a roof ages, it’s more prone to issues. So if your roof’s seen a couple of decades, show it some love with regular inspections and maintenance.

Solution: Schedule routine inspections to ensure the health of your roofing system. If the roof is beyond repair, it may need to be replaced.

#5  Debris Buildup

A buildup of leaves, branches, and dirt causes nothing but problems for flat roofs. The excess debris can attract animals like rats, squirrels, and birds, and the added weight can put stress on its structure. 

Solution: The debris can be removed by sweeping or hosing it off.

#6 Flashing

Flashing is one of the most important parts of any roofing system. It protects vulnerable spots on the roof, like around vents and chimneys, from water infiltration. But if the flashing is damaged or out of place, water can seep under the TPO membrane. Make sure to inspect your flashing during routine inspections. 

Solution: The flashing can be repaired or replaced by professionals, or as a DIY project.

#7 Leaks

If you notice water stains or discoloration on your walls or ceilings, there’s a good chance a roof leak is behind it. Leaks occur for many reasons, including punctures from debris, foot traffic, and general wear and tear. Any leaks that are found should be addressed immediately to prevent further water damage.

Solution: The leaks can be repaired by patching the affected area with a new piece of TPO roofing material.
