Flat Roofs are very popular, and when building a new flat roof, or reroofing an outdated flat roof, it’s important to know the options when it comes to the materials. First, let’s define what a “flat roof” is, and how it’s different from other roofing styles like shingles. A flat roof is a actually not perfectly flat, as they generally have a small pitch of a few degrees to them. Unlike shingle roofs, which have a much more intense pitch and slope, flat roofs are designed to allow water to stand for a short amount of time. They are build to hold more weight, and often drain via scupper drains.
The most popular materials for a flat roof include:
EPDM (Rubber): Known for its durability and resistance to extreme temperatures.
TPO (Thermoplastic Polyolefin): Offers excellent water-tightness and can last up to 30-40 years. TPO roofs often need more maintenance than other types, so be sure to take those costs into account when determining your best options.
PVC (Polyvinyl Chloride): Provides high energy efficiency and can last up to 30-50 years.
Standing Seam Metal Roofs: These are generally the most expensive option, but offers excellent longevity and eco-friendliness. Due to cost and time, these are less common and not often recommended for most homeowners and businesses.
No matter the type of materials you choose for your flat roof, be sure to have annual or biannual inspections and keep up on any recommended maintenance. This can greatly extend the longevity of your roof, as well as lessen the chance of leaks or any unnecessary damage.
