See maintenance options to see what’s available and how we can help.

Is summer the only time to replace my roof?

We provide roofing services year-round, including winter, backed by solid insurance coverage to protect you in case of any issues.

While summer is the busiest and often most expensive season with the lowest risk of water leaks, winter is usually more cost-effective. During winter, manufacturers, suppliers, and contractors often offer discounts due to better availability.

Not all roofing projects can start in winter. Contact us to explore your options and find the best time for your roof replacement.

What material is best for my roof?

The right roofing material depends on your roof’s pitch, your budget, local climate, and how long you want it to last.

For Low-Pitched Roofs

  • Silicone: Great for waterproofing and UV protection. Extends the life of existing roofs.
  • TPO (Thermoplastic Polyolefin): Lightweight, energy-efficient, and resistant to tears and chemicals.
  • PVC (Polyvinyl Chloride): Durable, fire- and chemical-resistant, and highly energy efficient.
  • Torch-Down: A strong, waterproof system using layers of modified bitumen applied with heat.

For Roofs with 3/12 Pitch or Higher

  • Asphalt Shingles: Affordable, flexible, and available in many styles and colors.
  • Metal Roofing: Durable, modern, and energy efficient.
  • Tile or Shake Roofing: Heavy, stylish and long-lasting, with a variety of textures and finishes.

What types of roofing materials do you offer?

We offer a variety of materials for roof replacement, including:

  • Asphalt and composite shingles
  • Metal roofing
  • Single-ply roofing systems (TPO, PVC, EPDM)
  • Torch-down (Modified Bitumen)
  • Built-up roofing (BUR)
  • Tile and slate roofing
  • Composite and synthetic roofing products

We also provide restoration services with silicone roofing systems.
