Flat Commercial Roof Issues

Common Flat Commercial Roof Issues

What are the most common issues with flat commercial roofs?

The most common problems with flat commercial roofs include leaks, standing water, and damage from a lack of maintenance or poor installation. These issues often lead to water getting into the building, higher energy bills, and costly repairs if not fixed.

What you actually see or experience

You might notice water stains on your ceiling, especially after it rains. Sometimes, water might even drip into your building. You could also see puddles of water staying on the roof for a day or two after rain, or notice cracks, blisters, or tears in the roof's surface. If your energy bills are going up, your roof's insulation might be wet and no longer working well.

Why it happens and what it costs if ignored

Flat commercial roofs are designed to shed water, but they're not always perfectly flat. Over time, parts of the roof can settle or sag, creating low spots where water collects. This is called ponding water. If water sits on your roof for too long, it finds its way into cracks and seams, leading to leaks. Leaks can also start because the roof material gets old and breaks down from sun, heat, and cold. Seams can pull apart, or flashing around vents and edges can crack. Sometimes, the roof was not installed correctly in the first place, or repairs were done poorly, creating weak spots. Not cleaning debris off the roof or not fixing small problems early on also speeds up this breakdown. If these issues are ignored, water will rot the roof deck and insulation. This can lead to mold inside the building, damage to equipment, and even structural problems. Wet insulation stops insulating, so your heating and cooling systems have to work harder, driving up your energy bills. Eventually, ignoring these problems leads to needing a full, expensive roof replacement sooner than you should.

How a Conklin-trained contractor fixes these problems

Most flat commercial roof issues can be fixed with a commercial roof restoration using a Conklin acrylic coating system. Our Conklin-trained contractors follow a proven process: 1. **Inspection:** First, we do a thorough inspection of your existing roof. We check for leaks, areas of ponding water, damaged seams, and wet insulation. We take moisture readings to find out if the insulation underneath is dry or wet. 2. **Repair and Preparation:** * **Wet Insulation:** If insulation is wet, we open up the roof, remove the wet sections, and replace them with new, dry insulation. If too much of the roof is wet, a coating might not be the right solution for you. We'll tell you honestly if that's the case. * **Deck Damage:** If the roof deck is rotted or structurally unsound, we have to address that first. A coating system needs a solid surface to stick to. * **Surface Cleaning:** We clean the entire roof surface, removing dirt, debris, and any loose materials. This makes sure the coating will stick properly. * **Patching and Sealing:** We repair any cracks, blisters, or holes. All seams, fasteners, and flashing around pipes, vents, and edges are reinforced and sealed with specialized materials to prevent future leaks. * **Addressing Ponding Water:** For areas with significant ponding water, we might add extra material to build up those low spots, helping water drain better. 3. **Primer Application (if needed):** Depending on your existing roof material, we may apply a primer coat to ensure the acrylic coating bonds strongly. 4. **Base Coat:** We apply the first layer of the Conklin acrylic coating. This forms a seamless, waterproof membrane across your entire roof. 5. **Top Coat:** Finally, we apply a highly reflective top coat. This white layer reflects up to 85% of the sun's UV rays, which keeps your building cooler and reduces stress on the roof material, making it last longer. This process turns your old, leaking roof into a seamless, watertight, and energy-efficient system without the need for a costly tear-off and replacement.

Frequently Asked Questions

What types of flat roofs can be restored?

Conklin acrylic coatings can be applied to many types of flat commercial roofs, including TPO, PVC, EPDM, modified bitumen, built-up roofs (BUR), and even spray polyurethane foam. Each roof type might need slightly different preparation, but the goal is the same: a seamless, watertight finish. You can learn more about specific systems at our roof systems page.

How long does a restored flat roof last?

A properly applied Conklin acrylic coating system can add 15 to 20 years or more to your existing roof's life. This comes with a non-prorated material warranty from Conklin and often a full-system warranty that covers both materials and labor. Regular maintenance helps extend its life even further.

Is a roof coating cheaper than replacing the roof?

Yes, typically a commercial roof coating costs significantly less than a full roof replacement. This is because we don't have to tear off the old roof, which saves on labor, disposal fees, and material costs. It also means less disruption to your business operations.
