TPO is a popular choice for commercial and residential flat roofs due to their durability and energy efficiency. Being a relatively new addition to the industry, TPO roofs have now become a go-to choice for new properties, and they adhere to all building codes.
It’s crucial to understand that even with its exceptional qualities, TPO roofs can face issues over time. We know that as a home or a business owner, you probably aren’t thinking much about your roof. That’s why we have made this short, easy-to-read guide for TPO roof repair so you can keep focusing on what matters most.
Assessing The Damage On Your TPO Roof
The first step in TPO roof repair is to assess the damage. Though these single-ply roofing membranes are known for their durability and longevity, like any roofing material, they can be susceptible to wear and tear over time.
By regularly inspecting your roofing system, you can spot signs of damage to your TPO roof. Be it residential or commercial, you need to inspect your roof twice a year. However, unless you are a trained professional, you may not be able to fully assess the condition of your roof. In cases like this, it’s better to hire a professional roofing contractor.
Signs Of Damage
One of the most obvious signs of TPO roof damage is visible tears or punctures in the membrane. These cracks can occur due to a variety of factors, such as extreme weather or improper installation.
Another sign of underlying damage is blistering or bubbling on the surface of the membrane. This occurs when moisture becomes trapped between the roofing layers, causing the membrane to separate from the roof deck.
The next type of damage involves loose seams or edges. Over time, the adhesive that holds the seams and edges of a TPO roof together can deteriorate, causing them to become loose and potentially separate from the rest of the membrane.
Gathering All Your Tools
Whether you are inspecting or repairing your roof, some tools are needed. Common tools required for TPO roof repair include:
- TPO Patch Kit: Includes TPO patches and adhesive.
- TPO Repair Tape: For repairing damaged seams and punctures.
- TPO Roof Sealant: To seal punctures and small leaks.
- Heat Gun: For heat-welding TPO seams.
- Roof Cleaner: Non-abrasive cleaner for surface preparation.
Safety First: Preparing for Repairs
Before you start any repairs, prioritize safety. Ensure you have proper footwear, gloves, and eye protection. Also, work on a clear, dry day to prevent accidents or injuries.
Start The Repairs
After gathering the equipment, taking safety precautions, and preparing the roof, you are ready to begin repairs. In this section, we will go over common problems TPO roofs face and give tips on how to fix them.
#1 How To Repair Leaks In A TPO Roofing Membrane
Identifying the Source of the Leak
Start by pinpointing the source of the leak. If there are water stains inside the building, the leak isn’t always right below. Water can travel along the roofing materials before making an appearance on walls and ceilings.
Patching Small Leaks
For small leaks, clean the area around the leak and apply TPO sealant. Smooth it out and ensure a watertight seal. This should stop the leak if it’s minor.
Sealing Larger Leaks
For larger leaks, use a TPO patch kit. Cut the patch to size, apply adhesive, and press it down firmly. Heat-weld the edges for a secure bond.
#2 Repairing TPO Roof Punctures
Inspect the roof carefully, paying close attention to potential puncture points, which are often caused by sharp objects like debris, tools, or foot traffic.
Patching By Heat-Welding
Once you’ve identified and marked the puncture points, it’s time to patch them. Patching will require you to use heat welding and other methods, which necessitates the help of professional contractors.
Using TPO Sealant
Clean the area around the puncture gently using a mild cleaner to remove any dirt, dust, or debris. This ensures that the sealant adheres properly to the TPO membrane. Next, apply the TPO sealant generously over the puncture. Use a putty knife or a similar tool to spread the sealant evenly and ensure that it covers the entire punctured area.
#3 Fixing A TPO Roof With Quality Roof Tape
There is another way in which you can repair the damages such as punctures and gaps: with roof tape.
For example, if you discover any issues with your TPO roof seams, it’s crucial to address them promptly. One effective method for re-seaming damaged areas is to use TPO roof repair tape, also known as TPO seam tape. These are easily available in local retail stores and you can also buy them online from Amazon or Home Depot.
Here is how you can use seam tape to seal a roof puncture:
Cut The TPO Roof Tape
Measure and cut a piece of TPO roof tape that covers the punctured area with some overlap. The tape should be larger than the puncture to ensure complete coverage and effective sealing.
Using a heat gun, gently warm the area around the puncture and the TPO roof tape. Heat-welding the tape to the TPO membrane enhances the bond and ensures a waterproof seal.
Position and Press
Carefully position the TPO roof tape over the punctured area. Using protective heat-proof gloves or a flat tool, press down firmly to ensure complete contact between the tape and the membrane. The heat from the heat gun will help the tape adhere securely.
Other Common Problems With TPO Roofs
There are some other issues that you can face with your TPO roof. These are often the result of poor-quality membranes or lack of maintenance.
Addressing Ponding Water
Ponding water is a common issue on flat roofs. It adds extra weight and can lead to leaks.
To solve this issue, you need to pay attention to the drainage. Improve drainage by adding tapered insulation to create a slope. This encourages water to flow towards drains, preventing ponding.
Enhancing Your TPO Roof System
TPO Roof Coatings
If you are looking for ways in which you can improve your existing roofing system, then consider adding a TPO roof coating. These coatings provide an additional layer of protection against leaks, debris, and UV rays.
Keeping Your TPO Roof Dust and Debris Free
One way to improve the longevity of your TPO roof is to keep it clean. Over time, dust and other debris can accumulate on the surface, leading to premature deterioration. Leaves, branches, and twigs can create perfect nesting areas for unwanted pests like birds, squirrels, and mice. Drainage may also be impacted if water cannot properly flow off the roof, leading to further water damage.
Should You Hire A Professional?
While the DIY steps we’ve outlined in this guide provide some tips for addressing various TPO roof repair issues, it’s important to acknowledge that roof repairs can be challenging and intricate tasks. Hiring a professional roofing contractor brings a multitude of benefits to the table. DIY roof repairs can increase the damage rather than fix the problem, leading to more expensive repairs later on. With a professional, there is less chance of improper repairs and mistakes due to a lack of experience with tools or materials.
