Second-Generation Roofers Protecting Chicagoland Homes
Guardian Roofing Systems is a second-generation roofing crew out of Alsip, and the habits were set by the family that built it: a supervisor on every roof, the site clean at the end of the day, and a straight answer before any work starts.
Shingle, metal, flat and TPO roofs. Gutters. Storm damage and the insurance paperwork that comes with it. Homes, warehouses, churches and everything between, from our shop in Alsip across the south suburbs and the whole Chicago area.
A+ rated with the BBB. HomeAdvisor Elite Service award. Licensed and insured in Illinois. Quick pricing over the phone using satellite measurements, and help getting financing approved before work begins.
What We Do
Twenty-seven services, seven trades, one crew. Every one gets its own page because every one is its own job.
Shingle And Metal Work, Each Its Own Trade
Most houses around Alsip and the south suburbs wear asphalt shingles, and we install them the slow way: full tear-off, deck inspection, ice and water shield where Illinois winters demand it, then architectural shingles nailed by hand where it matters. Metal roofs get the same patience, panel by panel. A shingle roof done right here should ride out 25 Chicago winters without drama, and the difference between that roof and the one that fails at year twelve is almost always in the tear-off and the flashing, the parts you never see from the driveway.

Flat Roofing, TPO Included
Flat roofs are our specialty and always have been. Chicago two-flats, three-flats, additions and garages carry more flat roofing than almost any city in the country, and we install, repair and replace all of it: TPO membrane, modified bitumen, and coatings that buy an aging roof years. Ponding water, blistered membrane, flashing pulling away from a parapet wall, we have seen every way a flat roof gives up and we know which ones are a patch and which ones are a replacement conversation.

Storm Work, Claims Handled
When hail or straight-line wind comes through Cook County, we patch first and argue with the weather later. We document everything the way adjusters need it and walk your claim through with you, because a homeowner should not have to learn insurance language the week their roof opens up. Tarps and emergency patches go on fast to stop the bleeding, then the permanent repair gets scheduled once the claim is squared away.

Gutters
A good roof with bad gutters is still a water problem. We hang seamless gutters sized for real Midwest downpours, repair what can be saved, and replace what cannot. Sagging runs, separated seams, downspouts dumping against the foundation: all of it is fixable, and most of it costs far less to fix now than the basement repair it causes later.
Commercial Buildings, Industrial Plants
Warehouses, restaurants, churches, townhome associations and factories all sit under roofs that cannot afford downtime. We handle scheduled inspections, leak response and full systems on buildings where closing for a week is not an option. Property managers get one point of contact, photo reports they can forward to a board, and crews that work around your operating hours instead of through them.

A Family Trade, Run The Family Way
This company started the way most good roofing outfits do: on family crews, carrying bundles, learning why a valley gets woven. The second generation took it over and modernized it: satellite measurements for fast, honest pricing, financing help before the job, photo documentation for every insurance claim.
What did not change is the part that matters. Every job runs under a supervisor who answers for it. When you call, you reach a member of the team responsible for your roof, not a call center. Our trade network across Chicagoland means flashing, carpentry and gutter work get coordinated instead of subcontracted into chaos.
Thirteen years in, the jobs have gotten bigger. The habits have not. Bundles still get carried, tarps still go down over the landscaping, and the last thing that happens on every job is a magnet sweep for nails, because the house rule is that a customer should never find evidence we were there except the roof itself.

How A Job Runs
No mystery, no vanishing act between the handshake and the invoice. The same four steps on a bungalow or a warehouse.
You Call
We pick up or call back the same day. Tell us what the roof is doing. Emergencies jump the line.
Straight Price
Satellite measurements plus an on-roof look where it counts. You get a real number fast, and financing help if you want it.
Supervisor On Site
Crews arrive when we said they would. A supervisor runs the job start to finish. Materials match the quote, no swaps.
Walkthrough
We walk the finished roof with you, run the magnet for nails, haul the debris and leave the yard the way we found it.
Contract said they would arrive Thursday at 9am. Thursday at 9am sharp, two trucks pulled up and the employees were set up and working on the roof within fifteen minutes. Job was done within three hours.
Robert Dixon · Google review
Water was coming down into all three apartments. They sent the crew out the next day as promised, in blizzard conditions, shoveled the ice off and patched it.
Jimmy Proctor · Chicago three-flat owner
Their prices were competitive with the other quotes we received, but their service, quality of work and warranty put them on top.

Where We Work
Home base is Alsip, on the southwest edge of Chicago. From there we cover a 50-mile radius: the city itself, all of suburban Cook, DuPage and the Fox Valley in Kane, Will County to the south, and Lake County to the Wisconsin line. Five counties, 165 towns, one crew. That radius is a working range, not a marketing line. The trucks are in Oak Lawn and Blue Island weekly, downtown for flat roof work on multi-unit buildings, and out to Joliet and Naperville for full replacements. If your town is not listed, call anyway. The full service area map has every community we roof.
Questions We Actually Get
How fast can you get someone out for a leak?
Usually within a day, sometimes the same day. One December a landlord called on a Friday night with water in all three apartments of his Chicago three-flat. The crew was on the roof the next morning in blizzard conditions. That is the standard we hold ourselves to, weather included.
Do you give prices over the phone?
Yes, for most residential work. We pull satellite measurements of your roof while you are on the line and give you a realistic number. Complicated roofs and anything structural get an in-person look first, because guessing on those helps nobody.
Will you deal with my insurance company?
We document the damage the way adjusters need it, meet them on the roof, and make sure the scope covers what the storm actually did. You make the decisions on your claim. We make sure nothing gets missed. Start with our roof insurance claims page if a storm just came through.
Shingle, flat or metal, which do you actually do?
All three, every week. Shingles cover most of the houses we work on. Flat roofing, TPO and coatings cover Chicago’s two-flats and commercial buildings, and that has been a specialty of ours from the start. Metal work runs from repairs to full panel systems.
Are you actually licensed and insured?
Licensed and insured in Illinois, A+ rated with the BBB, and holders of a HomeAdvisor Elite Service award. Paperwork is available before the job starts, not after you ask twice.
Do you help with financing?
We help you get pre-approved before the work begins, so the size of the project does not decide the timing of it. Ask when you call, or mention it on the contact page.
Talk To Guardian Before The Next Storm Does The Talking
