About This Service
The Only Material That Gets Better With Age.
01
100+ year lifespan
Copper from the 1920s is still on homes in Winnetka and Lake Forest today.
02
Gets stronger over time
The patina is a protective oxide layer — copper becomes more durable, not less.
03
Unique to every installation
No two copper roofs age identically. It becomes part of the building’s identity.
04
Very few contractors can do this
Hand-soldering and precise fabrication. We’re one of the few on the North Shore who still do it in-house.
Where Copper Goes on Your Home.
We’ll tell you which profile performs best for your roof geometry, budget, and weather exposure.
01
Bay Window Roofs
02
Dormers & Turrets
Complex geometry. Hand-soldered seams conform to any angle — no caulk shortcuts.
03
Chimney Crickets & Caps
The most common failure point on luxury roofs. Custom-fabricated to your chimney’s exact dimensions.
04
Half-Round Copper Gutters
Soldered joints — no snap-together sections. Architecturally correct for period North Shore homes.
05
Covered Entries & Porches
High visibility from the street. Where copper’s quality is immediately apparent.
06
Custom Flashings
Wall-to-roof junctions, skylight curbs, valley liners — fabricated to your exact geometry.
The Workshop
Every Piece Made Here.
We don’t order pre-formed components. Every flashing, panel, and gutter section is cut and formed in-house.
Most contractors outsource copper work — and lose quality control at the most critical step.

Owner on every project
Mark oversees all copper work personally.
How long does copper roofing last in Illinois?
Properly installed copper roofing lasts 100+ years. Examples from the 1910s and 1920s are still weathertight on North Shore homes in Winnetka, Lake Forest, and Glencoe today.
What copper applications do you handle
Bay window roofs, dormers, turrets, covered entries, chimney crickets and caps, half-round copper gutters, and custom architectural flashings. All fabricated and hand-soldered in-house.
Is copper more expensive than other metals?
Copper has a higher upfront cost. Divided over a 100-year lifespan with zero replacement cost, the per-year expense is often lower than steel or aluminum alternatives.
Does copper require maintenance?
Minimal. The patina is itself a protective coating — no painting or sealing required. Periodic inspection every 5–10 years is recommended.

Posted on Google Ed TaleysnikTrustindex verifies that the original source of the review is Google. I can’t recommend enough working with **Black Square Roofing & Exterior, Inc.** and especially Mark. From start to finish, the experience was outstanding. The quality of work speaks for itself — every detail was handled with incredible care, precision, and professionalism. What truly sets Mark apart is his passion for perfection. He treats every project like it’s his own and never cuts corners. His attention to detail, communication, and commitment to doing things the right way made the entire process stress-free and enjoyable. Beyond being a true professional, Mark has also been a great friend and trusted partner to **Bravo Theater**. It’s rare to find someone who combines craftsmanship, integrity, and genuine care for their clients the way he does. If you’re looking for a company that delivers exceptional results and stands behind their work, Black Square Roofing & Exterior, Inc. is the one to call. Highly recommended!Posted on Google Daniela CwajbaumTrustindex verifies that the original source of the review is Google. A great job, on time and reasonable price. Highly recommend!Posted on Google anton madalliTrustindex verifies that the original source of the review is Google. We just had our roof done last week, and Mark managed the entire project. He even helped us with the design, which turned out great. On top of that, his guys noticed that our backyard sliding door wasn’t working properly and helped fix it on the spot. Way to go, guys — we will definitely recommend your business!Posted on Google Gene VTrustindex verifies that the original source of the review is Google. Mark was recommended to me by a contractor about 12 years ago. He replaced my room and gutters, ant the time I didn't know much about "good or bad" roof, but when I was selling my house few years later, I heart one of the realtors (he told me later that he used to be a roofer) tell his clients that rood on that house is done so well that it will outleave that house (and it was a brick ranch that wasn'tgoing anywherewith the next storm). When I purchased a new house, it had a "new" roof that was done by the company recommended by insurance adjuster. About a year after moving in I started heaving problems with it (my chimney was leaking, piece of plywood on my garage roof rotted out...) he was always there for me as soon as I called, and everything was done the right way. ( Saving money now for the new roof in siding, so Mark can get it done and I can forget about it forever)Posted on Google Robert MarshalTrustindex verifies that the original source of the review is Google. Really good work appreciate your work!!!Posted on Google Stepan KobzeyTrustindex verifies that the original source of the review is Google. Mark and his team did a great job fixing my roof after issues left by a previous contractor. They repaired problems with the stucco wall, properly installed flashing where it had been done incorrectly before by a different contractor, and removed and replaced rotten wood siding, custom-cut to the correct length and width. They also resolved a long-running issue with the balconies where water was getting into the house, replacing the rotten flooring with composite material. Communication was clear, they explained everything along the way, and were very professional. Highly recommend.Posted on Google Eugene FoxTrustindex verifies that the original source of the review is Google. Have used them on several occasions - from regular house repairs (roofing and exterior) to dealing with major hail storm consequences. Can't say enough good things. The owner and his crews work with highest quality and unparalleled attention to detail. Owner has decades of experience in this area and is able to help with making right decisions without upsell. Cannot recommend this business high enough.
