Built Around The Rail Yards, Roofed The Same Way

Industrial Roofs Along The Belt

The buildings packed around the Indiana Harbor Belt yard and out toward the airport are warehouses, freight terminals, machine shops and light manufacturing, most of them under wide low-slope decks. A lot of them have been added onto over the decades, which means one building can carry three different roofing systems that meet at transitions nobody detailed properly. Those transitions are where we find leaks far more often than the middle of any single roof.

Drainage is the other thing worth watching on these big flat decks. Interior drains clog with debris, deck deflection creates ponding areas that never dry out, and standing water finds any seam that has aged. Ponding water breaks down a membrane faster and puts real weight on the deck after a heavy rain. When we inspect here we check every drain and note where water is sitting, because fixing drainage is usually cheaper than replacing what the standing water eventually ruins.

What We Do On The Commercial Side

• Warehouse roofing on freight and distribution buildings, including phased work on very large decks.
• Industrial roofing for shops and plants where equipment, exhaust and foot traffic are hard on the membrane.
• TPO roof repair on seams and flashings, plus TPO installation when a deck is ready for a new system.
• Commercial roof leaks traced through the deck to the real source, with photos of what we found.
• Metal roof repair on the older steel-panel buildings scattered through the industrial blocks.

Anything large or long-term gets a commercial roof inspection with a written condition report you can put in a capital budget. We would rather map out three years of planned work with you than sell one emergency at a time.

The Houses The Plants Built

Franklin Park’s residential blocks are compact postwar housing: small frame and brick ranches, capes and story-and-a-halves built through the late 1940s and 1950s on modest lots, plus some newer infill. They were built efficiently and they have held up, but the roofs on them have been replaced two or three times, and the quality of those replacements is all over the map. We regularly find overlays, undersized flashing and vents cut in without proper flashing kits.

Our approach on these houses is boring on purpose. Tear off to the deck under shingle roof replacement, replace any bad sheathing at a price you agreed to in writing first, install ice-and-water membrane at the eaves and valleys, flash the penetrations correctly, and vent the attic so the new roof lasts as long as the shingle warranty claims. Smaller problems get handled as shingle roof repair when the field still has life, and gutter installation usually rides along, since the original runs on a 1950s ranch are undersized for the downpours we get now.

Wind Off The Open Ground

The yards, the runways and the wide industrial parcels leave a lot of open ground here, and open ground means wind with nothing to slow it down. On houses that shows up as lifted tabs and torn ridge caps on the exposed slope. On flat commercial roofs it shows up as edge metal peeling back or membrane billowing where the perimeter fastening was never right, and once the edge goes, a big section can follow in one storm. Perimeter detailing is the part of a commercial roof we look at hardest, and wind damage repair is one of the more common calls we take from this village.

Rooftop Equipment Is Half The Leak List

Every one of these buildings carries hardware up top: makeup air units, exhaust fans, condensers, refrigeration lines, conduit runs and the occasional dust collector. Each one sits on a curb, and every curb is a hole somebody cut in a perfectly good roof. Curb flashing is where we find a large share of Franklin Park leaks, usually because a mechanical contractor set a new unit on an old curb, or ran a line through the deck and sealed it with whatever was in the truck. Pitch pockets dry out and crack in about five years, and nobody goes up to look at them until a ceiling tile drops in the office below.

When we take on a building here we photograph every penetration and grade it, so you know which curbs are sound, which need new flashing and which are actively wet. We also ask who else gets on your roof. If your HVAC company is up there twice a year, foot traffic pads along their walking route cost very little and stop the punctures that come from dropped tools and dragged ladders. That coordination is cheap. Chasing a leak through a suspended ceiling and a rack of inventory is not.

Straight Answers From The Owner

Guardian Roofing Systems is second generation. Angelo Ristich learned the trade from his father Frank, runs the company now, and is on the job in person rather than sending a salesman and disappearing. On a commercial building that means your maintenance contact talks to the person who was actually on the roof. On a house it means the same.

We are BBB A+ rated, hold a HomeAdvisor Elite Service award, and stay licensed and insured in Illinois. Routine residential work can be priced from satellite measurements while you are on the phone, financing help is available if a full roof is a stretch this year, and every commercial scope gets walked before it gets quoted. The gallery shows the work, and the contact page gets you a callback the same business day.
