What We Repair

Complete Flat Roof Repair Solutions

Every flat roof system is different. Our team is certified across all major flat roofing systems and failure types, delivering precise repairs that last.

TPO Membrane Repair

We weld, patch, and re-seam thermoplastic polyolefin membranes, restoring the waterproof barrier without a full tear-off when the substrate is sound.

EPDM Rubber Roof Repair

Cracked seams, punctures, and shrinking edges on EPDM roofs are expertly patched using manufacturer-approved adhesives and cover strips for a watertight seal.

Modified Bitumen Repair

Our crews torch-apply or cold-process new bitumen over blistered, cracked, or split sections — blending seamlessly with existing layers to extend service life by years.

Ponding Water & Drainage

Standing water is a flat roof's biggest enemy. We re-slope, install tapered insulation, and clear or add drains to eliminate pooling before it deteriorates your membrane.

Blister & Bubble Repair

Trapped moisture causes blisters that eventually crack open. We cut, dry, and re-seal blistered areas before they spread or allow bulk water intrusion into your insulation layers.

Flashing & Edge Repair

Damaged or lifted metal flashing at parapets, penetrations, and roof edges is a leading cause of interior leaks. We replace, re-caulk, and secure all flashing to re-establish a continuous weather barrier.

I can't say enough good things about Alta Property Services. My basement flooded due to a burst hot water heater connection--right in the middle of trying to sell my home. It was a stressful situation, but Alta came through in the clutch. My realtor contacted them, and they responded quickly and professionally. They handled everything with the insurance company, which was a huge relief, and got right to work on the cleanup and restoration. Not only did they mitigate the water damage, but they also installed beautiful new flooring--all in time for us to keep our scheduled open house. Thanks to Alta, the space looked better than ever, and we were able to stay on track with the sale. I highly recommend them to anyone dealing with unexpected property damage. Fast, reliable, and truly went above and beyond.

We had a leak in our kitchen break room. I called Alta and they had some techs on site within an hour or so. They were able to clean up the water, had mold testing done, got us a quote to replace drywall, rebuild cabinets, and put everything back together as if it never happened. We are very appreciative for the help Alta provided. All of this at a very reasonable cost as well. They are now our "go to" company for emergency services. Thank you Alex and Ron.

Alta Property Services has helped my clients on projects large and small. And their work and customer service are exceptional! The owner Ron has always been quick to communicate (not always the case with contractors) and the folks he has working for him really know their stuff! Peter is one of the project managers and is not only organized but also helps come up with creative solutions when needed. Highly recommend!

Our tech, Chris went above and beyond in coming to our house and completing the job. This all happened in sub zero temps in Chicago. After a long day, Chris called and provided an update on where he was and timing of when he would be able to be at the house. He was willing to come after hours (arrived at 7:30PM) and did a great job fixing 2 toilets and ensuring the job was complete before he left - and all with a smile. He was polite, professional and super helpful with explaining what he was doing. Great example of what great service looks like.

I’m extremely happy with the service we received. We have a home warranty and Alta was dispatched to correct a plumbing issue with our toilet, it was taking forever to fill after flushing. I’ve had this problem for about 2 years now, my warranty company has sent out multiple plumbers (2-3) who’ve attempted to fix the issue but were unable and just provided me with different excuses as to why it’s not fixed, like that I have low pressure etc, when the toilet wasn’t like that when we bought the house…I’ve been under the impression we had a leak this whole time, our water bill has been outrageous so I finally called the warranty company again on the same issue and was so relieved to find out Alta was easily able to correct the problem. I guess the 3rd/4th turn is a charm. Finally a plumber who knows what they’re doing, thank you Alta! I’m hoping our water bills will be more affordable now as a result 🙏🙏

Common Questions

Flat Roof Repair FAQ

Answers to the questions we hear most from Chicago-area property owners about flat roof repair.

If the membrane is less than 15–20 years old, damage is localized, and the insulation beneath is dry, targeted flat roof repair is almost always the right choice. If more than 25–30% of the surface is compromised, the insulation is waterlogged, or the membrane has reached the end of its service life, replacement may be more cost-effective long-term. Our free inspection gives you an honest recommendation either way. Learn more about our full roof replacement services.
Flat roof repair costs in Chicago and DuPage County typically range from a few hundred dollars for minor puncture or blister repairs to several thousand for larger membrane sections or drainage corrections. The type of membrane (TPO, EPDM, modified bitumen), the extent of damage, and accessibility all affect pricing. Alta provides a detailed free estimate before any work begins — call (630) 461-9229 or request yours online.
Yes, with conditions. EPDM and TPO repairs using cold-applied adhesives can be performed in temperatures above 40°F. Torch-applied modified bitumen is often preferred in colder Chicago winters. Emergency leak stop and temporary weatherproofing can be done year-round. We'll be upfront about which methods are appropriate for the temperature on the day of your repair so the work holds long-term.
It can, if repairs aren't performed using the correct roofing solutions and methods. Alta's technicians use manufacturer-approved products and application techniques, which in many cases preserves or can even reinstate an existing manufacturer warranty. We'll review your warranty documentation before starting and let you know exactly how the repair will interact with your coverage.
Damage caused by sudden events — severe weather, high winds, falling debris — is typically covered by homeowner's or commercial property insurance. Gradual wear and maintenance neglect usually is not. Alta specializes in insurance-supported restoration coordination; we document damage thoroughly, work with your adjuster, and can bill your insurer directly on covered claims, reducing the paperwork burden on you.
A properly executed flat roof repair can add 5–15 or more years of service life, depending on the overall age and condition of the roof and the quality of roofing products used. TPO and EPDM membrane patches done correctly are essentially permanent on that section. The rest of the roof's longevity depends on ongoing maintenance. Alta offers annual flat roof inspection plans to catch problems early and maximize your roof's lifespan.
