Roof Replacement & Recover

Your Roof is Our Proof.

When repairs and coatings are no longer enough, we help you find the right path forward and install a roofing system built to protect your building for decades.

When Does a Commercial Roof Need Replacement?

Every commercial roof has a limited service life. Recognizing when replacement makes more sense than continued repairs and coatings helps you plan ahead and avoid costly unplanned failures.

Recurring Leaks

Leaks that keep coming back despite multiple repairs usually mean the membrane has deteriorated beyond what patches can fix.

Widespread Membrane Damage

Cracking, splitting, blistering, or granule loss across large sections of the roof indicates the system is failing, not just damaged in spots.

Saturated Insulation

When moisture has reached the insulation layer, thermal performance drops and the added weight stresses the structure. Wet insulation cannot be dried and must be replaced.

Ponding Water

Standing water that doesn't drain within 48 hours accelerates membrane breakdown and adds unnecessary load to the roof structure.

Visible Structural Issues

Sagging deck areas, deteriorated metal decking, or compromised connections mean the problem goes beyond the membrane and insulation.

Age Beyond Service Life

If your roof has reached or passed the manufacturer's expected service life, the risk of failure increases with each passing year.

Two Paths Forward

Recover or Full Replacement

When it's time for a new roof, we evaluate whether a recover or a full tear-off is the right approach. We lead with recover whenever the building qualifies because it saves you money and time.

Preferred

Recover (Overlay)

A new roofing system installed directly over the existing one. No demolition, less waste, and up to 40 percent lower cost than a full tear-off. Available when the building still carries only one roof system and the deck underneath is sound.

When Required

Full Replacement (Tear-Off)

Complete removal of every existing layer down to the structural deck, followed by a brand new system. Illinois code allows only two roof systems on a building, so once a second system is already in place a recover is no longer permitted and a full tear-off is required. Going back to the deck is also the right call when trapped moisture, added weight, or load and structural limits mean the building cannot safely carry another layer.

Our Proof-of-Value Roof Inspection can determine which path is right for your building before any number is on a proposal.

System Options

Five Roofing Systems. The Right One for Your Building.

The right roofing system depends on your building, your budget, and how long you plan to hold the asset. We walk you through the options and help you pick the one that makes the most sense.

  • TPO. Reflective single-ply with heat-welded seams. The most common commercial membrane.
  • EPDM. Rubber single-ply with a 50-year track record.
  • PVC. Chemical-resistant single-ply for restaurants and food processing.
  • Modified Bitumen. Multi-ply asphalt system for high-traffic roofs.
  • Standing-Seam Metal. Maximum longevity for industrial and high-wind applications.

Frequently Asked Questions

Key indicators include recurring leaks that don't resolve with repairs or coatings, widespread membrane damage (cracking, splitting, blistering), saturated insulation, ponding water that doesn't drain within 48 hours, visible structural sagging, and a roof that has exceeded its expected service life. A professional Proof-of-Value Roof Inspection with core samples and moisture probes provides the most accurate assessment.

Roof replacement is a full tear-off down to the structural deck followed by installation of a new system from insulation to membrane. Roof recover is a new system installed over the existing one. Illinois code allows a maximum of two membrane systems on a commercial roof. If your building has only one existing system, a recover is on the table and we lead with it because it saves up to 40 percent versus a full replacement. If two systems are already in place, code requires a full tear-off. We confirm which path applies with core samples and moisture probes during the Proof-of-Value Roof Inspection.

Illinois code limits a commercial roof to two membrane systems. If a building has only the original system in place, code allows a single recover (a new system installed over the existing one). If a recover has already been done and the roof currently has two systems, the next step must be a full tear-off replacement back to the structural deck. This is the primary code factor that drives the recover-versus-replace decision in Illinois.

Commercial roof replacement in the Chicago suburbs typically runs $7 to $14 per square foot for tear-off and replacement of a TPO, EPDM, or PVC system, depending on insulation R-value, deck type, and number of penetrations. Mod-bit and metal systems vary outside that range. Recover projects generally come in at 60 to 75 percent of replacement cost. Every Americanstruction proposal includes a fixed scope, line-item pricing, and a cost-per-year analysis tied to the warranty term.

A 50,000 square foot tear-off and TPO replacement typically takes 10 to 15 working days from mobilization to final QA. Larger industrial roofs (150,000+ SF) run 4 to 8 weeks. Recover projects are 30 to 40 percent faster because there is no demolition phase. We commit to a project schedule before mobilization and provide daily progress updates with photo documentation.

Almost never. We sequence work to keep building operations running. Our crews protect interior tenant spaces from debris, schedule loud or odor-producing work outside of business hours when needed, and never leave open deck overnight. Tenants and operations leaders receive a daily look-ahead so deliveries, dock activity, and rooftop equipment service are coordinated around active work zones.

We install TPO, EPDM, PVC, modified bitumen, and standing-seam metal systems. We are factory-certified by Mule-Hide, FiberTite, and GenFlex, allowing us to issue manufacturer NDL (No Dollar Limit) warranties up to 30 years. The right system depends on building use, rooftop chemistry, energy goals, hold period, and substrate condition.

Yes. We replace commercial roofs through Chicago winters using cold-weather adhesives, mechanically fastened systems, and temporary heat where applicable. Productivity is lower than summer, but replacements after structural failure or severe wind events cannot wait for spring. We schedule winter work to maintain weather-tight conditions every night.

Our certified installations qualify for manufacturer NDL warranties of 20 to 30 years from Mule-Hide, FiberTite, and GenFlex. NDL stands for No Dollar Limit and means the manufacturer covers full repair or replacement if the system fails within the warranty term, with no capped payout. Americanstruction also provides a workmanship warranty covering labor for 2 to 5 years depending on system. Warranty documentation is delivered to the property owner at project closeout.
