Continue reading to review some frequently asked questions about flat roof systems.
What is a Flat Roof?
Any roof that has slight roof pitches between 1/4″ to 1/2″ per foot and slopes less than 10 degrees is considered a flat roof. For this reason, they are also known as “low-slope” roof systems. Roof pitch simply refers to the slope, angle, and slant of your roof. A roof’s pitch is represented as either two numbers divided by a slash, or as a ratio with a colon between two numbers. The first number is the numerator, and the second number is the denominator. Each number represents a specific measurement of a roof’s slope. The numerator represents the vertical height of a roof’s slant, while the denominator represents the horizontal length of a roof’s slant.
How Much Does a Flat Roof Cost?
Costs vary from property to property and from company to company. They depend on a long list of factors, making each and every project cost unique to its project needs. Factors like material quality, square-footage, existing roof condition, region, and more, play a large role in the overall estimate for purchasing and installing a flat roof system. However, the average flat roof system costs range from $250 to $350 per “square” (100 square feet). Most come with warranties as well, either from the manufacturer or the service company, or both. With proper installation and maintenance, flat roof systems can last up to 30 years.
What is the Best Material for a Flat Roof?
There are many types of materials that can be used for flat roof systems. However, the 4 primary types include built-up roofing (BUR), modified bitumen (cap sheet roofing), EPDM rubber roofing (ethylene propylene diene monomer), and PVC or TPO single-ply membranes. Other materials include elastomeric spray on coatings such as butyl, acrylic, polyurethane foam, or silicon. The best material for your property depends on several factors, which can all be professionally assessed by a licensed Indianapolis roofing company. Trust them for accurate advice and information.
What is the Lifespan of a Flat Roof?
Flat roof systems generally come with 10 to 20 year warranties, depending on the retailer, manufacturer, and more. If properly maintained, a flat roof can easily last 20 to 25 years or more. Maintenance includes keeping gutters and drainage systems free of debris and obstructions, as well as, routine roof inspections and minor repairs as needed.
What are the Pros and Cons of Flat Roofs?
Standing water and obstructed drainage are common problems associated with flat roofs since they do not readily shed water. This means that regular maintenance and gutter care is vital to prevent roof leaks and other similar water damages. Installation is another key factor in the lifespan and proper drainage of a flat roof, which is why it is critical to hire a licensed and insured roofing company who can perform quality work that lasts. On the other hand, there are several advantages of flat roof systems. They are easier and quicker to install because they lack slope and weigh less than standard roofing material like shingles or shakes. This also makes them cost less since materials and labor are cheaper. They are also eco-friendly and can allow for more interior living space.
