Should I repair or replace my current flat roof system?

Preparing for industrial flat roof replacement in Madison WI

Peeling back old roofing material in preparation for a full replacement.

It’s the question we hear the most. The best piece of advice we can give is to hire a flat roofing expert (like us!) to assess your roof’s current condition. Be wary of hiring run-of-the-mill general contractors or asphalt shingle roofers. Often they don’t understand the complexities of flat roofing systems and could give you advice that will drain your bank account.

How we determine if your flat roof needs repairs or replacement

An experienced flat roof contractor will thoroughly inspect all aspects of your roofing system, including the material, seams, flashing and attachment points. Then we’ll give you our honest opinion on whether or not the roof should be replaced or repaired.

Flat roof materials: Test cut checks material health underneath the top layer.

Flat roof seams: Check for seam strength and evaluate whether moisture is entering.

Flat roof flashings: Check to ensure flashings are still adequately connected to the membrane. (Most roof leaks are due to faulty installation or old flashings.)

Flat roof attachment points: Check to ensure the roof is still attached where it supposed to be.

Our goal is to educate you and help you make the best decision for your roof and budget, not just give you a sales pitch. Call us for a free estimate and roof inspection to get started.

Fixing Flat Roof Leaks the First Time

Evidence of water pooling problems and the need for commercial roofing repair

We fix & prevent water pooling on flat roofs.

Correctly identifying the cause of a flat roof leak as early as possible will save you money over the life of your roofing system.

Most common causes of flat roof problems:

  • Neglecting to keep up with flat roof maintenance
  • Membrane damage from severe weather including storms, hail and strong winds
  • Flashing around perimeter failing
  • Poor drainage caused by improper roof installation (flat roofs need a slight slope to allow water to run off)
  • Roof has reached the end of its service life (even a perfectly installed flat roof will not last forever)
  • Bad workmanship by some other roofing company*

*One of our clients came to us after using another commercial roofer who simply sprayed a coating on the roof without preparing the surface. It didn't even last one year before failing.

The most cost-effective way to maintain or replace a commercial roofing system starts with a free consultation from our experienced roofers. Whether we installed the roof or not, we’ll take a good look and recommend repair or replacement based on our findings.

Commercial Roof Restoration

What is roof restoration?

Roof restorations are commonly done on single membrane flat roofs when the roofing material has begun to reach the end of its service life. By adding a high-performance roof coating over your existing membrane, we can very cost effectively extend the life of the roof for another 10 to 15 years. At the end of the coating’s life, we can just apply a new coating over the old one, effectively deferring the cost of a completely new roof for another decade or more.

Flat roof restoration process

1. Inspect roof for cracks and other damage. Once we get up on your roof and take a look, we’ll be able to assess whether your roof is a good candidate for restoration or if it will need a roof replacement.

2. Prepare roof for new coating. A clean surface is essential for proper adhesion of the new coating. We’ll remove any debris and dirt using a power washer to make sure the surface is thoroughly clean, then allow it time to dry before applying the new coating. We’ll also make any necessary repairs, such as sealing leaks.

3. Apply new protective coating. We apply the new coating using a spray gun, or roller brushes when applicable. We work quickly to minimize interruption to your business, and most coatings will cure within a day or two.

U.S. Roofing has been restoring commercial and industrial flat roofs since 1979. Unlike many contractors who only take on commercial roofing jobs when the residential market slows down, we only work on commercial flat roofs and we will take on the work regardless of who installed the roof originally.

Most of our business is repeat business. Our customers tend to stick with us because of the quality of our work. When you contact U.S. Roofing, we’ll explain all your options and give you an honest opinion on the best plan for your roof.

Roof Restoration vs Replacement

A roof restoration involves making whatever minor repairs may be necessary and then applying a protective coating over the existing roofing material. This is an extremely cost-effective way to extend the service life of a roof, and can usually be done in one to two days.

We carry a full line of flat roof coatings and are happy to give you a recommendation and cost estimate for the best type of coating for your restoration project.

If your roof has degraded to the point where a protective coating won’t adhere to it properly, or there is a problem with mold growth or wood rot under the outer layer of your roof, we’ll likely recommend replacing your roof.

Since replacing a roof involves tearing off the old roof and installing a new one, the cost for materials and labor make roof replacement considerably more expensive than roof restoration. 

When roof restoration is possible, we highly recommend it over roof replacement. In fact, it makes no sense at all to replace a roof if a roof restoration can be done. Beware of contractors who are quick to tell you a full-on roof replacement is needed. It’s always a good idea to get an estimate and recommendation from experienced commercial roofers before making a decision.

Benefits of Commercial Roof Restoration

  • Costs significantly less than roof replacement. Although every job differs, a roof restoration typically averages $6 to $9 per square foot while roof replacement runs $18 to $26 per square foot.
  • Work can be completed in a day or two and doesn’t require you to close your business
  • Roof coatings create a seamless, waterproof membrane that stops leaks and resists ponding water
  • Application of a reflective coating will increase your building’s energy efficiency by reflecting UV rays
  • Coatings used are environmentally responsible and produce no noxious fumes
  • Tax benefits: With roof restoration, you can take the full deduction for the cost of the work instead of recovering the cost over a 39-year depreciation schedule (per federal income tax rules).

Types of Roofs We Restore

US Roofing can restore all common types of commercial and industrial flat roofing systems, including:

Built-up roofing. Built up roofing (BUR for short) is more commonly known as “tar and gravel” roofs or “gravel roof systems”). They’re made of alternating layers of asphalt or tar and reinforcing fabric (roofing felts reinforced with glass-fiber mats or organic mats) with a layer of gravel on top. These roofs can be coated with a variety of protective coatings.

Metal flat roofs. Metal roofing on commercial buildings is typically sheets of ridged metal joined together with screws. The most cost-effective restoration process is to apply a protective coating, although we can also attach sub-purloins to the existing roof and attach new metal panels to them.

EPDM flat roofs. EPDM (ethylene propylene diene terpolymer) is a single-ply rubber roofing membrane widely used on flat and low-slope roofs. Because EPDM retains its integrity and flexibility over time, it’s a good candidate for restoration with a protective coating—provided the roof is not mechanically fastened and the insulation board underneath isn’t wet or damaged.

TPO flat roofs. TPO (thermoplastic polyolefin) is a co-polymerized rubber that retains its flexibility in cold climates. As these roofs age, the seams and penetration flashings will fail, resulting in leaks when it rains or snow melts. TPO roofs can be easily restored with a variety of coatings.

Modified bitumen flat roofs. These are hybrid BUR roofs which use rolls of reinforcing sheets that are hot-mopped with heated asphalt or a torch to make it adhere to the subsurface. These roofs are good candidates for several types of coatings.

With several coating options available, your best course of action is to schedule a free roof inspection and discuss the different coatings available with an estimator.

Flat Roof Replacement Options

TPO Flat Roofs: single-ply roofing membrane, most popular material for commercial and industrial roofing systems. Benefits include cost savings, great durability and it is environmentally-friendly!

EPDM Flat Roofs: synthetic rubber roofing membrane used mostly on low-slope buildings. It’s created using oil and natural gas.

Metal Flat Roofs: have a 30 year lifespan, but are costly to install and remove. The main benefit is metal’s durability against the elements.

Built-up Roofs (BUR): multiple plies of felt, fabric and/or mats laid down in alternating layers – usually with gravel as the top layer.

Modified Bitumen: Factory-made asphalt modified with plastic or rubber ingredients with the purpose of being stronger than normal bitumen.

What is the best material for a flat roof?

TPO roofing membrane systems are the best! U.S. Roofing has been installing, fixing and maintaining flat roofs since 1979. We’ve considered the pros and cons of every flat roof type. TPO roofing systems cost less, last longer and are easier to repair and replace.

We'll fix or replace your flat roof using whatever materials you specify, though we believe TPO systems offer the best quality, performance and value for Wisconsin businesses.

How Tear-off Affects the Cost of Reroofing

Re-roofing a metal flat roof with TPO outside Madison Wisconsin

Replacing a metal flat roof with a new TPO system.

Naturally the first thing a building owner, business owner or property manager wants to know is: How much does it cost to replace a commercial roof?

The final cost depends on many factors, but mainly on whether or not we need to tear off your old roof.

Roof removal has a large impact on roof replacement costs and in some cases cannot be avoided.

Wisconsin building code allows no more than two layers of roofing material. If your current roof already has two layers we can’t add a third material on top.

A complete tear-off is needed when both layers of existing material are in poor condition, or if the outer layer can’t be removed without compromising the layer beneath it.

We’ll do a thorough evaluation of your roofing system and help you find the best overall option for your budget. Commercial roof restoration such as applying a coating system can extend the life of your roof and keep unnecessary waste out of Wisconsin landfills.
