What is a Flat Roof?

Flat roofing is common in commercial construction since it is economical and practical for maximum usable space inside and out. Commercial buildings also benefit from the space flat roofs provide for necessities like HVAC units or solar panels.

However, commercial flat roofs are never entirely flat — also grouped with low-slope roofs, flat roofs require a small pitch to allow water and snow run-off, ranging from ¼:12 to 3:12 rise over run (roughly 1 to 25 degrees).

Flat commercial roofing typically lasts much longer than high-pitched roofs since the materials are more durable. Most commercial projects use single-ply roofing materials like TPO, EPDM and PVC thermoplastic, which can last decades with proper installation and maintenance.

Types of Flat Roof Systems

While single-ply roofing materials are typical for commercial roofs, many more options exist. Carefully consider the type of roof you need to suit your building best, as an improper roof can lead to building damage and extensive repairs.

Flat Roof Material Options

EPDM, TPO, and PVC single-ply roofing materials last up to 40–50 years, provide UV ray reflection, have flexible membranes for easy installation, and offer good durability. Austermiller Roofing provides single-ply membrane roofing materials for your commercial projects in Tennessee.

Metal roofs, or metal panel systems, are one of the oldest roofing systems and prove very durable and heat resistant. Sealant goes in between metal panels to ensure water resistance. Although more expensive than single-ply, metal roofs are more durable and can last up to 70 years.

Green, garden, or vegetative roofs are gaining popularity with hospitality and event venue commercial buildings. Installation and maintenance are more expensive, but green roofs provide ecological benefits and a desirable aesthetic.

Flat Roof Installation, Maintenance, and Replacement in Tennessee

When you request a flat roof installation from Austermiller, we will first work with you to determine the best type of roof for your project. Depending on the size of your building, you can expect installation to take from 5 days to 3 weeks. If you need a roof replacement, we will clear and clean off any pre-existing roof, then install the layers necessary for the type of roof you need.

Once your flat roof is installed, schedule annual inspections from a professional at Austermiller Inc. to look for any punctures, loose flashing, or loose seams — and schedule an inspection after any significant weather event. These detailed inspections determine the need for repairs or flat roof replacement.

Regular inspections can increase the lifespan of your roof, but keep in mind that if you need a roof replacement, it could be that you chose the wrong kind of roof for your needs — consider requesting a different type of roofing system that may last longer.
