Are you the proud owner of an EPDM flat roof? Then you know how great they can be. They are cost-effective, durable, and require minimal maintenance. But like any roofing system, over time you may notice some common issues.
That’s why we’re here—to give you a comprehensive guide on EPDM roof repair. We’ll discuss the most common problems associated with EPDM flat roofs and provide practical solutions for quick repairs.
Our professional and experienced team of roofing experts have you covered. We’ve got all the tips and advice you need to keep your EPDM roof in top shape. So, let’s get started and explore the best ways to repair and maintain your EPDM roof.
1. Improper Installation
Causes
One of the primary reasons for EPDM flat roof repair needs is improper installation. This can be due to untrained or inexperienced roofing contractors or inadequate preparation of the roof surface. Some common installation mistakes include:
- Not cleaning, drying, and preparing the roof surface properly
- Using an incompatible substrate or not adding a protective barrier
- Applying the EPDM membrane when the surface is wet or damp
- Not adhering the membrane correctly to corners, walls, drains, and pipes
Solutions
To avoid EPDM roof leak repair requirements due to poor installation, make sure to hire a reputable and experienced roofing contractor. They should be fully trained in installing EPDM flat roofs and be familiar with the best practices for ensuring a long-lasting and watertight roofing system. If you suspect that your roof has been installed improperly, it's best to consult with a professional roofer for an assessment and possible repair options.
2. Shrinkage
Causes
Shrinkage is another common issue that may require EPDM flat roof repair. Over time, EPDM rubber can draw back due to factors such as aging, poor maintenance, and exposure to direct sunlight. This shrinkage can cause the membrane to pull away from parapet walls, flashings, and other areas, creating gaps through which water can penetrate and cause leaks.
Solutions
There are two possible solutions here. To begin, you can reflash the affected areas, which involves removing the old flashing and installing new material that is properly bonded to the membrane. If the shrinkage is more extensive, re-sealing may be necessary. In this case, you can remove the old product and install a new sealant that is compatible with the EPDM membrane. Either way, you can rest assured that your roof will be fixed quickly and efficiently.
3. Leaks and Moisture
Causes
Leaks are a common problem for EPDM flat roofs, especially if they haven't been adequately maintained or were installed poorly. Heavy rainfall can exacerbate existing issues and lead to more severe gaps. Some possible causes of leaks in EPDM roofs include:
- Improper installation
- Shrinkage
- Damaged or worn seams
Solutions
If you notice a leak, it's essential to identify the source as soon as possible and consult with a professional roofer for an inspection and repair. EPDM roof leak repair can involve patching damaged areas, reinforcing seams, or even replacing sections of the membrane if necessary.
4. Puddles of Water
Causes
Pooling water on your EPDM flat roof is another common issue that can lead to more significant problems if left unaddressed. This can occur due to changes in the structure of the roof as your building settles over time or inadequate drainage systems.
Solutions
To prevent this, you can apply a roofing patch or increase insulation. If your roof doesn't have enough drain lines, you can easily install more. To further divert water away from roof protrusions, consider installing roof crickets. Finally, if your roof is not properly pitched, you can re-pitch it by adding more insulation or installing a new roof membrane.
5. Mold and Mildew Growth
Causes
Molds and mildews can be a concern for EPDM flat roofs, as they can cause unsightly stains and be difficult to remove. While EPDM rubber does not contain any materials that promote mold or mildew growth, prolonged exposure to moisture and varying weather conditions can create an environment conducive to their development.
Solutions
If you notice mold or mildew on your EPDM flat roof, use a non-abrasive cleaner and a soft-medium brush to clean the affected areas. Regular cleaning and maintenance can help prevent the growth of mold and mildew and keep your roof looking its best.
6. Damaged or Worn Seams
Causes
Over time, the seams of your EPDM flat roof can become damaged or worn. This can happen due to regular wear and tear, improper installation, or exposure to harsh weather conditions. Damaged seams can allow water to infiltrate your roof and cause leaks.
Solutions
Depending on the severity of the damage, you may be able to repair the seams yourself using a roofing patch or sealant. If the damage is more extensive, you may need to replace the seams with the help of a professional roofing contractor. In the most severe cases, the best option may be to install a new roof so you can ensure the best protection from leaks. Whatever the case, our team of professionals is always here to help you find the best solution for your needs.
7. Bubbling
Causes
Bubbling or blistering can occur on EPDM flat roofs when air or moisture becomes trapped between the membrane and the roof surface. This can be due to improper installation, inadequate roof surface preparation, or using an incompatible substrate.
Solutions
If you’re noticing some small bubbles on your roof, you’re in luck – you may be able to repair them yourself with a roofing patch or sealant. However, if the bubbles are larger or more numerous, it’s best to call a professional roofing contractor for EPDM roof repair services.
8. Punctures and Tears
Causes
Punctures and tears can occur on EPDM flat roofs due to impacts from falling debris, foot traffic, or other external factors. These damages can compromise the integrity of the roof and lead to leaks.
Solutions
Regular roof inspections can help identify punctures and tears before they become more significant problems. A professional roofer can patch or repair damaged areas to maintain a watertight roofing system.
9. Flashing Issues
Causes
Flashings are crucial components of a flat roof that help seal and protect transition areas, such as where the roof meets walls or chimneys. Over time, flashings can become damaged, corroded, or poorly adhered, leading to leaks.
Solutions
A professional roofer can inspect and replace damaged or worn flashings as needed, ensuring a watertight seal around all transition areas of your EPDM flat roof.
10. Maintenance and Inspection
Regular maintenance and inspections are vital in preventing many common EPDM flat roof repair issues. This should include:
- Cleaning debris and dirt from the roof surface
- Inspecting for signs of damage or wear, such as punctures, tears, or worn seams
- Checking flashings and other transition areas for proper adhesion and seal
- Assessing drainage systems and addressing any pooling water issues
It is recommended that you have your roof inspected at least twice a year, ideally in spring and fall, to ensure that any problems are detected and addressed promptly.
