The Top 5 Signs It’s Time to Replace Your Commercial Roof

Your commercial roof is a vital component of your business infrastructure, protecting your assets, employees, and customers. However, like all building materials, roofs have a finite lifespan and will eventually require replacement. Recognizing the signs that it’s time for a commercial roof replacement is crucial to avoid costly damage and ensure the continued success of your business. In this guide, we’ll explore the top five signs that indicate it’s time to replace your commercial roof and how WaterTight Roofing can assist you in this important endeavor.

1. Persistent Leaks and Water Damage

One of the most obvious signs that your commercial roof needs replacement is persistent leaks and water damage. If you notice water stains on your ceiling, or interior walls, or have recurring leaks during rainy weather, it’s a clear indication that your roof’s waterproofing has been compromised. Ignoring these issues can lead to extensive interior damage, mold growth, and increased repair costs. A new roof with modern waterproofing materials can prevent further water intrusion and protect your property.

2. Extensive Wear and Tear

Commercial roofs are exposed to the elements 24/7, which can cause wear and tear over time. If your roof is nearing the end of its expected lifespan (typically 20-30 years for most roofing materials), you may notice signs of deterioration such as:

• Cracked or Curling Shingles (for Asphalt or Shingle Roofs): Asphalt shingles are a popular roofing material known for their durability and cost-effectiveness. However, over time, they can show signs of aging. Cracked or curling shingles are typical indicators of roof deterioration. Here’s what these signs mean:
  • Cracked Shingles: Cracks in shingles can occur due to the natural aging process, prolonged exposure to sunlight, and extreme weather conditions. These cracks allow moisture to penetrate the roof, leading to leaks and water damage inside your building.
  • Curling Shingles: Shingle curling often results from the expansion and contraction of roofing materials due to temperature fluctuations. When shingles curl, they lose their ability to provide adequate protection against water intrusion. Wind can also catch beneath curled shingles, causing them to lift, crack, or break.
• Replacing cracked or curling shingles is a temporary fix, and if these issues are widespread, it may be more cost-effective to invest in a complete roof replacement. A new roofing system will provide better protection and increase the overall energy efficiency of your building. Blistering, Cracking, or Alligatoring (Surface Cracking) on Built-Up Roofs: Built-up roofs (BUR), commonly known as tar and gravel roofs, are durable and long-lasting when properly maintained. However, they can show signs of wear and aging, such as blistering, cracking, or alligatoring (surface cracking):
  • Blistering: Blisters are pockets of trapped moisture that form beneath the surface of the roofing material. Over time, these blisters can rupture, leading to further damage and water infiltration.
  • Cracking: Cracks in the roofing material can occur due to thermal expansion and contraction and exposure to UV rays. These cracks weaken the roof’s integrity and make it susceptible to leaks.
  • Alligatoring (Surface Cracking): Alligatoring is a pattern of fine cracks that resemble the scales of an alligator. This typically happens as the roof ages and experiences years of temperature fluctuations and exposure to the elements.
• While routine maintenance can extend the lifespan of a built-up roof, extensive blistering, cracking, or alligatoring may indicate that a roof replacement is necessary. A new roofing system will enhance your commercial property’s protection and energy efficiency. Rust, Corrosion, or Holes in Metal Roofing: Metal roofing is known for its durability and longevity, but it is not immune to wear and tear, especially if it’s not properly maintained. Signs of deterioration in metal roofing include:
  • Rust and Corrosion: Metal roofs can rust over time, especially if they are exposed to moisture and are not adequately coated or protected. Corrosion weakens the structural integrity of the roof and can lead to leaks.
  • Holes: Holes can develop in metal roofing due to rust, corrosion, or physical damage caused by fallen debris or severe weather conditions. These openings allow water to penetrate the roof, potentially causing interior damage.
• If your metal roof shows extensive rust, or corrosion, or has developed holes, it’s essential to consider a replacement. Modern metal roofing materials offer superior corrosion resistance and energy efficiency, ensuring a longer-lasting and more dependable roofing solution. Split or Cracked Single-Ply Membrane Roofing (e.g., EPDM, TPO): Single-ply membrane roofing systems like EPDM (ethylene propylene diene terpolymer) and TPO (thermoplastic olefin) are known for their flexibility and durability. However, like any roofing material, they can show signs of wear over time, including:
  • Splitting: Splitting occurs when the membrane material develops long, linear cracks. These splits can weaken the roof’s ability to repel water and protect your building from leaks.
  • Cracking: Cracks in single-ply membranes can result from prolonged exposure to UV rays, temperature fluctuations, and natural aging. Cracked membranes are more prone to water infiltration and damage.
• If your single-ply membrane roofing system exhibits widespread splitting or cracking, it may be time to consider a replacement. Modern single-ply membranes offer improved durability and energy efficiency, ensuring that your commercial property remains well-protected.

If your roof exhibits these signs, it’s a strong indication that replacement is a more cost-effective option than constant repairs.

3. Sagging or Uneven Roof Surface

A sagging or uneven roof surface is a serious structural issue that demands immediate attention. If you notice dips, sags, or areas of the roof that appear uneven, it may indicate underlying structural damage or weakening of the roof’s supporting framework. Continuing to use a compromised roof can pose significant safety risks and further damage to your property. A professional inspection can determine whether a full roof replacement is necessary to address this issue.

4. Frequent Roof Repairs

Have you found yourself repeatedly calling for roof repairs? While routine maintenance and occasional repairs are part of commercial roof care, excessive repair needs can be a sign that your roof is past its prime. Constantly patching up an aging roof can become more costly in the long run than investing in a new, reliable roofing system. A reputable roofing contractor can assess the situation and recommend a cost-effective solution, which may include a full roof replacement.

5. Decreased Energy Efficiency

Commercial roofs are essential for maintaining indoor comfort and energy efficiency. If you’ve noticed a significant increase in heating or cooling costs, it may be linked to an inefficient roof. Older roofs often lack adequate insulation and energy-efficient materials, causing your HVAC systems to work harder to maintain the desired indoor temperature. A new, energy-efficient roofing system can help reduce utility costs and create a more comfortable working environment for your employees.
