FAQ
Frequently Asked Questions
Does Flat Roof Pros specialize only in flat roofs?
While flat roofs are our specialty, we handle all roof types—flat, low-slope, and pitched. As we like to say, most roofs are flat; it all depends on the angle you're looking at them. No matter the slope, we bring the same level of expertise and quality to every project.

Are estimates free?
Yes! We offer free, no-obligation estimates to help assess your roofing needs. In some cases, a trip charge may apply depending on your location—but we’ll always let you know upfront.
How do I know what service my roof needs?
→ Flat Roof Restoration Ideal for roofs that show signs of wear but remain structurally sound. Restoration can extend the life of your roof by adding protective coatings or repairs, delaying the need for a full replacement.
→ Roof Replacement Recommended for roofs with severe damage, structural issues, or advanced aging. If your roof has widespread leaks, sagging, or other major concerns, a full replacement ensures lasting protection.
→ Roof Repairs Best for addressing minor issues such as small leaks, missing shingles, or isolated damage. Targeted repairs are effective for preserving roof integrity and preventing issues from worsening.
→ Regular Roof Maintenance Essential for all roofs, regular maintenance involves cleaning, inspections, and minor fixes that help prevent costly problems and extend roof lifespan.

Is summer the only time to replace my roof?
Summer is typically the busiest and most expensive time to have your roof done. While it carries the least risk of water leaks, it comes with higher prices. The best and most cost-effective time to schedule your roofing project is during the winter season.
During this time, manufacturers, suppliers, and roofing contractors often offer discounts due to improved product and crew availability. That said, we provide a solid insurance policy to ensure that our clients are covered in case any issues or emergencies arise during the winter.
Please note that not all roofing projects can begin in the winter season. Contact us, and we’ll be happy to explain your options and the next steps to take.
What material is best for my roof?
Choosing the best roofing material depends on factors like longevity, pitch, cost, and climate:
For Low-Pitched Roofs
Silicone: Silicone coatings offer excellent waterproofing and UV protection, restoring the life of your roof.
TPO (Thermoplastic Polyolefin): TPO membranes are lightweight, energy-efficient, and highly resistant to tears, punctures, and chemicals.
PVC (Polyvinyl Chloride): PVC roofing is durable, resistant to fire and chemicals, and provides excellent energy efficiency.
Torch-down: Torch-down roofing consists of layers of modified bitumen applied with a torch, providing excellent waterproofing and durability.
3/12 Pitch and Up Roofs ONLY
Shingles: Asphalt shingles are affordable, versatile, and come in various styles and colors to suit your aesthetic preferences.
Metal roofs: The tough, stylish armor perfect for ultimate protection and energy efficiency.
Tile and shake roofs: Heavy, stylish, and longer-lasting roof protection that comes in many different forms and aesthetic looks.
