Flat Roofing Contractor Hilton Head South Carolina

Flat roofing is a common choice for both commercial and residential properties. As the name suggests, flat roofing is characterized by a very low slope or a completely flat surface. In this section, we’ll delve into the specifics of what flat roofing entails and also explore some of its key benefits.

Flat Roofing

Defining Flat Roofing

Flat roofing is a type of roofing system where the roof has either no slope (meaning it is totally flat) or a very slight slope. This contrasts with pitched or sloped roofs, which have a more pronounced angle. Flat roofing is not completely flat but typically has a slight pitch, about 1/4 to 1/2 inch per foot, to allow for water runoff and drainage. Flat roofs can be made from various materials including modified bitumen, EPDM (ethylene propylene diene terpolymer), or TPO (thermoplastic olefin) membranes. This type of roofing is favored for its simplicity in design and ease of construction.

Key Benefits of Flat Roofing

  1. Cost-Effectiveness: Flat roofing generally requires fewer materials and less labor than pitched roofs, which can result in cost savings. 
  2. Additional Space: The flat surface of the roof can be utilized for various purposes such as rooftop gardens, installing solar panels, or even creating a recreational space.
  3. Easy Access: The flat surface makes it easier to access the roof for maintenance, repairs, or installations compared to sloped roofs. 
  4. Design Versatility: Flat roofing can be designed using a variety of materials, offering more options in terms of appearance and functionality. 
  5. Energy Efficiency: By incorporating reflective coatings or insulation materials, flat roofs can be designed to reduce heat absorption, which lowers cooling costs and improves overall energy efficiency. 
Space Efficiency for Interior: Flat roofs eliminate the need for attic space, which maximizes interior space – a benefit particularly advantageous for commercial buildings.

What Our Customers Say

"We discovered Alliance about a year ago in 2022, and they have cleaned our roof twice since then. Our roof had been cleaned more than 20 times prior to that by several other roofers and "jobbers" but none did nearly the quality of work for a reasonable price. They are a professional organization from the workers to the front office. I highly recommend them.”

Tom Gardo

"It was a wonderful experience to be able to have Alliance replace my roof. Brian and his team show exceptional and complete service. From meeting with the adjuster to filing the paperwork necessary for my insurance, Brian showed total professionalism. On the work site, the cleanup was meticulous. I hope I do not have any roof problems in the future, but if I do, I will totally call Alliance. Happy to be in their family now!”

A crew was made available to get the work done on a day’s notice and at a time that was convenient to me. The crew arrived on time and completed the work in a professional manner. They were very pleasant and answered all of my questions. I certainly will recommend Alliance to my friends.”

I highly recommend Alliance Roofing for any roofing needs you might have. Very satisfied.”

"What a wonderful company. Smooth process from beginning to end. Samantha in the main office always got back to us promptly with any questions. Brian who oversaw the operation from day one until the last inspection could not have been more professional. Bill and his crew who installed the roof worked non-stop for 2 days getting the rip off and new roof installed without a hitch. Recommend without hesitation.”
