Commercial Roof Replacement

A full roof replacement is one of the largest capital decisions a property owner or manager makes on a building, and we approach it that way: a clear written scope, a realistic schedule that works around your tenants, and a system selected for how the building is actually used rather than a one-size-fits-all install.

When Replacement Beats Repair

Most commercial roofs give plenty of warning before they fail outright. The signals that usually tip the decision from repair to replacement are:

• Leaks in more than one area. A single leak is a repair. Leaks showing up in different parts of the building point to a membrane that is failing system-wide.
• Wet insulation. Once water gets under the membrane and saturates the insulation, patching the surface does not fix the problem. A core sample or infrared scan tells us how much of the roof is wet.
• Membrane past its service life. Single-ply and modified bitumen roofs have a finite life. Past that point, every repair is money into a roof that will need to be replaced anyway.
• Widespread ponding, blistering, or seam failure. These are signs the roof is losing the fight, not isolated defects.
• Storm or structural damage that affects a large percentage of the roof area.

If you are not sure which side of that line your roof is on, a roof assessment answers it. We would rather tell you a repair or a restoration coating will get you five more years than sell you a roof you do not need yet.

What a Cardin Replacement Includes

Every replacement follows the same sequence so there are no surprises for you or your tenants:

1. Inspection and written scope. We walk the roof, check drains, penetrations, flashings, and deck condition, and put the full scope in writing: system, insulation, tapered design if needed, warranty, and schedule.
2. Tenant and operations plan. For occupied retail, office, multi-family, and warehouse buildings we plan staging, crane or hoist days, noise windows, and access so operations keep running.
3. Tear-off and disposal. The old system comes off down to the deck. Deck repairs are documented with photos before anything goes back on.
4. Insulation and new system. New insulation and cover board as specified, then the new membrane: TPO, EPDM, modified bitumen, or shingle depending on the building.
5. Flashings, drains, and details. This is where most roofs actually fail. Curbs, parapets, drains, and penetrations get the most attention, not the least.
6. Closeout. Final inspection, photo documentation, and warranty paperwork for your files.

Roof Systems We Install

The right system depends on the building. Low-slope warehouses and retail boxes usually call for TPO or EPDM single-ply. Buildings with heavy rooftop traffic or equipment often do better with modified bitumen. Pitched multi-family and institutional buildings get architectural shingle. If the existing roof is structurally sound but simply worn, a silicone restoration coating can defer replacement entirely. We recommend based on the building, not on what we happen to have on the truck.

What Drives the Cost of a Commercial Roof Replacement

Every roof is quoted individually, but the same factors move the number on almost every project: total square footage, the number of layers coming off, the condition of the deck underneath, the insulation thickness and whether a tapered system is needed to fix drainage, the quantity of rooftop equipment and penetrations that need flashing, roof access and crane requirements, and the warranty term you want. A written scope from us breaks each of those out so you can compare it line by line against other bids.

Buildings We Replace Roofs On
