Understanding The Different Types Of Commercial Roofs


Nowadays, roofing materials are numerous and manufacturers


keep working on improving them. We present you some of the most common types of commercial roof materials that are used by local Dallas commercial roofers and others.

Single-Ply Membrane

This is a very popular commercial and industrial roofing option that passed the test of time. It consists in sheets of rubber and other synthetic materials applied on the insulation, to form a protective layer.  Besides durability, single-ply membrane provides some other advantages too: considering that it has been used for years, it has a proven track record, it is rated class A when it comes to fire resistance and it can be easily customized to be retentive or reflective, depending on the climate.

Spray Polyurethane Foam

SPF consists in a liquid which is sprayed on a flat roof and expands into foam that creates a resistant protective layer. It is an environmentally-friendly roofing option, which can be used regardless of the climate and which typically lasts for a few decades. Additionally, it provides a high R-value.

Sheet Of Metal Roofing For Commercial Buildings

Metal sheet

Metal roofs for commercial buildings are made from galvanized steel, aluminum or tin. Metal sheets are a lightweight material; it can be installed on an existing roof and also coated for additional protection against rust, water and UV radiation.


How Hail Affects Flat Roofs

Flat Roof Repair From Hail

Hail is a weather phenomenon that has the potential to cause significant damage to any type of roof. When it comes to flat roofs, specific mostly to commercial buildings, it is important to identify vulnerable areas, know the type of damage that may be inflicted by a hailstorm, as well as ways to prevent this damage.

The most common materials flat roofs are made of include single-ply membranes, metal panels and multi-ply asphalt systems.

Typically, the most vulnerable areas of a flat roof are the corners and the edges – and that`s because the uplift pressure of the wind. In these areas, the roofing coat can peel back more easily and then start to lift up.

On these roofs, hail can cause cosmetic damage or some larger problems, depending on the size of the hailstones and the roof coating materials. In the case of a metal roof, even small hail can dent the material, compromise its finish and expose it to water damage. Single-ply roofs can also experience some serious damage, especially if regular maintenance is ignored by owners.

Conducting roof inspections periodically is essential in minimizing the vulnerabilities of a roof and maximizing its capacity to withstand hailstorms and other severe weather phenomena.  Don’t put off roof inspections after a hail storm, call on local professionals like https://www.jntdevelopers.com.
