Slate roofs are built to last, but they are not maintenance-free. When something goes wrong, the way it gets repaired matters just as much as the repair itself. The wrong approach can crack surrounding slates, compromise the underlayment, or introduce incompatible materials into the original installation.
Todco Roofing has been handling slate roof repair in Chicagoland for over 30 years. We know how to get onto a slate roof without causing additional damage, diagnose what is actually wrong, and fix it in a way that lasts.

Todco was very professional and easy to work with. Having a clay tile roof in Chicago made it difficult to find someone who could do the work and do it well, Todco did a fantastic job and we are pleased. Would recommend and use again.Posted on Al DeBonnettTrustindex verifies that the original source of the review is Google. Haris, Elizabeth, Maestro Paul and the entire Todco Roofing team performed a perfect symphony of professionalism and customer service. Bravo! As a person who has more than 30 years of experience in real estate and financial services, I can honestly say that the Todco roofing experience has been the best. As a result of our experience with Todco, I can comfortably refer my many former clients, family and friends to Todco.

Short Version We recently moved into a 1920s home with a clay tile roof and discovered water damage in the master closet. The original sellers who promised to fix the roof leak used a general roofer who “fixed” the roof. Couple month later, we found mold and active leaks. Todco stood out with quick responses, cheapest quote, and great communication. Although they’re under new management, the same experienced crew is still there. Paul, the foreman, explained everything clearly and did excellent work. They fixed the issue in three days and I’ve already booked them for more repairs. If you have a tile roof, I highly recommend Todco—they know their stuff and do it right. Long Version Todco doesn’t have any recent comprehensive review, so I am going to chime in a long version. We recently moved into a historic district, where our 1920s home still has its original clay tile roof. When we bought the house, we noticed water damage in our master closet and asked the sellers to have the roof repaired. Unfortunately, they used a crappy general roofer who clearly had no experience with tile roofs. We thought the issue was resolved—our first big mistake. Three months later, we finally had a closet company come to fix our master closet. When they removed the damaged closet, we discovered a wet ceiling and significant mold growth. After some heavy rain, water was literally dripping from the ceiling. I reached out to the original roofer, who shrugged it off and said, “Tile roofs are tricky. You can’t really find the leaks. You fix what looks broken—you just need a whole new roof.” That didn’t sit right with me, so I turned to our neighborhood group and learned that tile roofs require specialists. I contacted three companies recommended by neighbors, including Todco. Every single one gave me the same answer: I didn’t need a new roof. The issue was likely due to poor flashing around the chimney and improperly installed tiles. Basically, the seller’s roofer didn’t fix anything and had no idea what he was doing. Many neighbors vouched for Todco, so I reached out. Haris responded quickly and was incredibly personable. He made me feel like fixing our roof was a top priority. He sent an estimator out right away, and their quote was the cheapest of the three. All the glowing neighborhood reviews were about the owner, Todd but I found out Haris is the new owner/manager (not sure which but was informed Todd has taken a step back but still involved). I couldn’t find any reviews about the new management and everyone I reached out to was with prior management. I was hesitant to sign, so I reached out to a neighbor, who contacted Todd for me. I even texted Todd directly. Shortly after, Haris called me to explain the transition and assured me the same experienced crew—Paul and Candelario—was still with them. That gave me the confidence to move forward. And I’m so glad I did. Paul, the foreman, was fantastic. He showed me the poor design of the flashing and the patch that gave out in the flashing. He walked me through the improvements they’d be making, and how the new flashing design was much more effective. The crew worked hard, kept me updated throughout the process, and completed the job in three days. They replaced the chimney flashing, installed new ice and rain shields, and re-tiled the affected area with care and precision. The work was excellent, and the crew was a pleasure to have around. Haris continued to follow up and support us throughout the process. I was so impressed that I’ve already booked Todco for a second job—to replace broken tiles elsewhere on the roof. I highly recommend Todco. They know tile roofs, and they take pride in doing things the right way. If you have a home with a roof, these are the people to call.Posted on Mike DilichTrustindex verifies that the original source of the review is Google. Todco recently repaired the slate roof on my 100 year old house in Evanston. Several random shingles were out of place and crooked. New copper flashing needed to be installed around the chimney. Paul from Todco repaired it all. He also painted some wood trim on the roof that could only be reached by hooking a ladder over the slates, in a place a normal painter could not reach without stepping on and probably breaking slates. Paul was the foreman on this job. I can't say more about how lucky I was to have Paul work for me. He searched for slates which needed to be repaired and repaired them all beautifully. He took the time to explain what needed to be done and what was not needed to be done and WHY. When I need roofing repairs done again in the future, I would hire Todco again in an instant. True professionals. And of course their cost was very reasonable and per their original quote. Thank you Todco, Mike D.Posted on Karin BirkelandTrustindex verifies that the original source of the review is Google. Great customer service and great result. Would definitely use Todco again!
Slate itself is remarkably durable. Most problems with a slate roof stem from the components around it rather than the slate itself. Common issues we diagnose and repair include:
A leak in a slate roof almost never originates where the water shows up inside the home. Water travels along rafters, sheathing, and insulation before it finds a place to drip, which means the visible stain on a ceiling can be several feet from where the roof is actually failing.
We approach every leak investigation the same way: start at the water entry point inside, trace the path back through the attic, and work our way up to the roof surface to find the true source. In most cases, it comes down to failed copper flashing or underlayment rather than the slate itself.
Chicagoland weather is hard on slate roofs. High winds, hail, and ice dam buildup during freeze-thaw cycles can all cause damage that is not visible from the ground but is actively allowing water into the roof system. After a major storm, it is worth having your roof looked at. The sooner damage is detected, the less likely it is to become a much larger problem.
Not every slate roof problem requires a full replacement, and not every problem can be solved with a simple repair. Here is a general way to think about it:
We will always give you a straight answer about which category your roof falls into.
We handle both residential and commercial slate roof repairs throughout Chicagoland. Residential repairs on historic homes in Oak Park, Evanston, and the surrounding suburbs make up a large part of our work, but we also have extensive experience on larger commercial properties, including historic churches, institutional buildings, and landmark structures.
Commercial slate roof repair comes with its own set of challenges, including larger roof areas, more complex architectural features, and, in some cases, preservation requirements tied to landmark designation. We are equipped to handle it all.
We provide slate roof repair in Oak Park and throughout the Greater Chicagoland area. Our service area includes:

How Do I Know If My Slate Roof Needs Repair or Replacement?
If the damage is localized and most of the slate is still intact, repair is likely the right call. Widespread deterioration, recurring leaks, or significant underlayment failure usually point toward a full slate roof installation. We will give you an honest answer after taking a look.
What Causes Slates to Slip or Fall Off?
Usually, corroded fasteners or failed copper hooks that can no longer hold the slate in place. It can also happen when slates were installed incorrectly in the first place. Either way, it is something that needs to be addressed quickly before water gets in.
Will Walking on My Slate Roof Cause Damage?
Yes, if done incorrectly. Slate is durable but brittle under direct pressure. Walking on it without knowing where to step can crack tiles and cause more damage than the original problem. This is one of the reasons slate work should always be handled by a specialist.
What Happens If I Delay a Slate Roof Repair?
A small problem becomes a bigger one fast. A couple of missing slates or a failed flashing can allow water into the underlayment, decking, and eventually the interior of the home. The repair cost grows significantly the longer it sits.
Are Slate Roof Repairs Covered by Insurance After a Storm?
In many cases, yes, particularly for storm or hail damage. We recommend documenting the damage and contacting your insurance provider promptly. We can help assess the damage and provide documentation to support your claim.
Can You Repair Just a Section of My Roof?
Yes. Targeted repairs are often the most cost-effective solution when damage is confined to a specific area. We assess the surrounding slate and structure to make sure the repair holds long-term.
Do You Handle Emergency Slate Roof Repairs?
Yes. If you have an active leak or sudden storm damage, contact us right away. We will assess the situation and take steps to protect your home while a permanent repair is planned.
