Choosing the Right Materials

Selecting the right materials for your commercial roof replacement is crucial. Here are some popular options:

  1. Asphalt Shingles: Affordable and easy to install, asphalt shingles are a common choice for many commercial buildings. They offer good durability and come in various styles and colors.
  2. Metal Roofing: Known for its longevity and durability, metal roofing is resistant to harsh weather conditions and fire. It is more expensive than asphalt shingles but can last up to 50 years or more.
  3. Single-Ply Membranes include TPO (thermoplastic olefin) and EPDM (ethylene propylene diene terpolymer) roofs. They are lightweight, flexible, and resistant to UV radiation and chemicals. Single-ply membranes are suitable for flat or low-slope roofs.
  4. Modified Bitumen: This type of roofing is similar to asphalt shingles but includes layers of bitumen. It offers excellent waterproofing and durability, making it ideal for flat roofs.
  5. Built-Up Roofing (BUR) comprises layers of asphalt and reinforcing fabrics. It is strong and offers great protection from water and UV rays. It is commonly used on flat or low-slope roofs.

Benefits of a New Commercial Roof

  1. Improved Energy Efficiency: A new roof can improve insulation and lower heating and cooling costs.
  2. Enhanced Safety: A sturdy new roof reduces the risk of leaks, water damage, and potential structural issues.
  3. Increased Property Value: A well-maintained roof enhances the property’s overall value and curb appeal.
  4. Business owners and occupants have peace of mind knowing that their building is protected from the elements.
