Replace, restore or repair?
A commercial roof is an asset on your balance sheet. Replacing it too late risks interior damage, tenant complaints and emergency costs. Replacing it too early wastes capital. Here is how to tell where yours stands.
✓ Leaks keep returning in different places despite repairs
✓ The membrane is cracked, blistered, shrinking or pulling away at seams and edges
✓ Insulation under the roof is wet, which can show up as soft spots or sagging
✓ Water pools on the roof for long stretches after rain
✓ The roof is near or past the typical life of its system
✓ Annual repair spending is climbing toward the cost of a new roof
✓ Problems are isolated to one area, such as a seam, flashing or penetration
✓ The roof insulation is dry and the deck is sound
✓ Regular inspections show the system is aging normally
✓ Clearing drains and repairing small defects early can extend its life
✓ You need a bridge solution while you plan a budget for replacement
Not sure? Start with a commercial roof inspection. We will tell you honestly whether to repair, maintain or replace, and a maintenance program can extend the life of a roof you are not ready to replace.

The right system depends on your building, budget, climate exposure and how long you plan to own it. We explain the trade-offs so you can choose with confidence.
Thermoplastic polyolefin. A popular single-ply membrane that is energy-efficient and durable.
A rubber membrane known for flexibility and long service life, well suited to many flat roofs.
Highly resistant to chemicals, fire and punctures, a strong choice for roofs with rooftop exhaust or heavy foot traffic.
A traditional layered system with a long track record of durability.
Reinforced asphalt-based sheets that are tough, flexible and widely used on low-slope roofs.
Durable, long-lasting and strong in harsh weather, ideal for warehouses and industrial buildings.

Budgeting
Commercial roofs vary too much for a single price range, so we do not guess. These are the factors we measure at your assessment, so you can budget and compare bids on equal terms.
Total square footage, number of roof levels, parapets, skylights and rooftop units all affect labor and material.
TPO, EPDM, PVC, built-up, modified bitumen and metal each have different material cost, install method and lifespan.
Removing the old system costs more up front but lets us inspect the deck. In some cases a recover over the existing roof is possible. Local code and roof condition decide.
Wet insulation must be replaced. Adding tapered insulation or fixing slope can solve ponding water, and adds cost but protects the new roof.
Tight sites, occupied buildings, crane or hoisting needs, and working around tenants all shape the schedule and price.
Permits, code-required insulation and the warranty coverage you want should be itemized in the bid, not discovered later.

How it works
A clear, documented process so you always know what happens next, from first walk-through to final sign-off.
1
We walk the roof, evaluate the existing system, drainage, flashing and penetrations, and talk with you about budget, timeline and how the building is used.
2
We recommend the best-fit roofing system, explain alternatives and trade-offs, and provide a written, itemized scope and price.
3
We plan phasing, material staging, safety measures and communication with your staff or tenants so the building keeps running.
4
Our crews install the new roof system to manufacturer specifications and safety standards, protecting the building and the people in it.
5
We do a final inspection, walk the finished roof with you and hand over warranty documents for your records.
Protecting your operation
Your priority is keeping your business or tenants undisturbed. We plan around that from day one.
✓ Phasing the roof into sections so only part of the building is exposed at a time
✓ Working hours and noisy tasks scheduled around your operating hours
✓ Marked material staging and dumpster locations that avoid entrances and parking
✓ Protection for rooftop equipment, skylights and HVAC units
✓ A single point of contact for the property manager or owner
✓ Give us roof access, building rules and any restricted areas before work starts
✓ Let tenants and staff know the dates, since noise can be expected
✓ Clear parking and entrance areas near the work zone
✓ Tell us about sensitive spaces below, such as inventory, servers or clinics
✓ Share building plans or past roof records if you have them
Compare bids
Commercial bids can look similar and still cover very different work. Use this checklist when you compare proposals, including ours.
The exact membrane or metal system, thickness, attachment method, flashing details and what is removed or kept.
How wet or damaged insulation is handled, what is required by code, and how ponding or slope problems are addressed.
What the manufacturer covers, what the contractor covers, duration, and what could void the coverage. Get it in writing.
Proof of liability and workers' compensation insurance, plus the safety plan for working at height and around occupied space.
Start date, expected duration, weather contingency and how work is phased around your operation.
Payment schedule, how unexpected deck or insulation repairs are priced, and how changes are approved before work is done.

“I needed to replace my roof right away due to leaks. ProLine Roofing was able to fit me in their schedule and replaced the roof just in time for the next storm. I want to thank Loni and his crew for such a fast response and reasonable price.”

FAQ
It depends on roof size, the system you choose, whether the old roof is torn off, insulation and drainage needs, and access. Because no two buildings are alike, we price after a free assessment and give you a written, itemized estimate.
Timelines depend on the size and complexity of the roof. In most cases the building can stay open because we phase the work and protect the area below. We agree the schedule and access with you in advance.
There is no single best system. TPO and EPDM are common on flat roofs, PVC suits roofs exposed to grease or chemicals, built-up and modified bitumen offer proven layered protection, and metal is strong for warehouses. We recommend based on your building and budget.
Sometimes a recover is possible, but it depends on the current roof, moisture in the insulation and local code. We check these at the assessment and explain the options and trade-offs.
Often, yes. Solutions include tapered insulation, improved drainage and a properly installed membrane. See our flat roofing page.
Manufacturer warranties on the roofing system, which vary by product and coverage level, plus our workmanship guarantee. We put the terms in writing in your proposal.
Yes. Our license is HIC #2120969-DCWP and our crews are insured. We are happy to provide proof of insurance on request when you compare bids.
Regular inspections, drain clearing and small repairs can extend a roof's life. If you are not ready to replace, see our commercial roof maintenance and inspection services.
We are available around the clock for urgent leaks. A temporary repair can protect the building while you plan and budget. Call (347) 323-9128.
