What Are The Layers Of A Commercial Roof In Selbyville, DE?

When my retail building in Selbyville, DE needed commercial roofing, I called Economy Roofing & Restoration. They carefully inspected the roof, explained all the layers, and replaced the old system with a durable TPO roof. Their team worked quickly through December’s rain and cold, cleared drainage, and added a reflective coating to keep my building safe and energy-efficient.

Why Did My Commercial Roof Start Leaking In Selbyville, DE?

I run a small retail store in Selbyville, and during early December, I noticed water stains appearing on the ceiling. Our building has a flat roof, and it has been over 15 years since any major work was done. Water pooling on the roof had started seeping inside, causing minor damage to ceiling tiles and even affecting some electrical fixtures.

I was worried about how much damage was happening and how soon it might get worse. Was it just a small leak, or was the entire roof failing?

Economy Roofing & Restoration explained that commercial roofs, especially flat ones, have multiple layers that work together to keep a building dry and insulated. Over time, exposure to winter storms, rain, and seasonal debris can compromise these layers. Heavy rainfall and leaves blocking drains can create localized water buildup, accelerating deterioration.

How Do The Layers Of A Commercial Roof Work?

During the inspection, Economy Roofing & Restoration walked me through the roof’s layers and how each one functions. A standard commercial roof has several key layers:

  1. Roof Deck – This is the foundation of the roof, made from wood, metal, or concrete. It supports every other layer and gives the roof its structure.
  2. Insulation – Placed above the deck, insulation regulates indoor temperatures and improves energy efficiency. On my flat roof, it also helps prevent ice formation in winter.
  3. Vapor Barrier – This layer stops moisture from reaching the insulation and the deck, reducing the risk of mold, mildew, and rot.
  4. Base Sheet – A protective layer that provides stability and helps secure the roof membrane.
  5. Roof Membrane – The top waterproof layer. My roof was replaced with TPO, which is durable, heat-reflective, and low-maintenance. Other options include EPDM and modified bitumen, but TPO was best for our flat, commercial roof.
  6. Reflective Coating or Finish – Some commercial roofs, including mine, have a reflective coating that extends the roof’s lifespan and improves energy efficiency during cold winters and hot summers.

Seeing these layers firsthand made me realize why my roof was leaking. The old membrane had cracks, and the insulation had absorbed some moisture. With winter storms approaching, leaving it untreated could have led to bigger issues inside the store.

How Did Economy Roofing & Restoration Handle The Roof Replacement?

The team started with a complete roof inspection, checking each layer for damage and weakness. They removed the old membrane, cleared debris, and inspected the deck. Any compromised sections were repaired before new layers were installed.

Next, they added the new insulation and vapor barrier, followed by the TPO roof membrane. The team used proper adhesives and seam welding to make sure the membrane was fully sealed. Even with December’s cold temperatures, they used equipment and techniques that allowed adhesives and coatings to bond properly, preventing future leaks.

They also addressed drainage issues by clearing blocked drains and slightly adjusting slopes where water had been pooling. Finally, a reflective coating was applied to improve energy efficiency and protect against winter ice and sun exposure in the coming months.

Economy Roofing & Restoration worked efficiently to limit disruptions to my store. I could continue operations while they installed the new roof, which was a relief during the busy holiday season.

The total cost of the commercial roof replacement was approximately $12,000–$18,000, which matches local averages for a flat roof of this size in Selbyville. The price included inspection, removal of the old membrane, replacement of insulation and vapor barriers, TPO installation, reflective coating, and cleanup.

The job timeframe was three days, accounting for preparation, weather delays, and careful installation. December weather can be unpredictable in Delaware, so the team monitored conditions closely to ensure safety and proper curing of adhesives. Completing the work quickly while maintaining quality gave me peace of mind during the holiday rush.

How Can I Maintain My Commercial Roof In Selbyville, DE?

How Often Should I Schedule A Roof Inspection In Selbyville, DE?

It is best to schedule inspections at least once a year, ideally before winter or after major storms. Regular inspections help detect early signs of wear or water buildup and prevent minor issues from becoming major problems.

Can I Do A Commercial Roof Replacement Myself?

Replacing a commercial roof yourself is not recommended. Professional contractors like Economy Roofing & Restoration have the proper equipment, experience, and knowledge of local weather patterns to safely and effectively complete the job.

Which Roofing Materials Are Best For Commercial Roofs In Delaware?

TPO, EPDM, and modified bitumen are common. TPO is energy-efficient, low-maintenance, and highly resistant to UV rays and winter conditions. Your contractor can help choose the best material based on your building type and location.

How Can I Protect My Roof During Winter Storms?

Keep drains free of leaves and debris. Schedule inspections before heavy snow or rain. Preventive maintenance reduces the chance of leaks or water pooling, which is especially important for flat roofs in Delaware’s winter weather.

What Should I Do If I Notice Water Stains Indoors?

Contact a professional roofing company immediately. Small leaks can signal larger issues with insulation or membrane layers. Early intervention prevents interior damage and costly replacements.
