Commercial Flat Roof Repair – Resources and Materials

The following materials are widely used in flat roof construction and repair:

Constructed Roof

This roof, also known as a tar or tar and gravel roof, is made up of 3-5 layers of asphalt laminated with coal hot tar, hot asphalt, or pitch. Finally, gravel is added to provide UV defence. This is becoming less common due to its short life, abundant heat gain, inefficiency, need for continuous maintenance, and aesthetically unappealing nature.

Bitumen that has been modified

This is simply mixed asphalt with plastic and rubber-like properties. Atactic Polypropylene and Styrene Butadiene Styrene are two widely used modifiers. When properly built, this roof will last for up to 15 years.

Installation of a Metal Roof

Metal roofs are usually built with both an underlying asphalt saturated roof and a coated roof. Underlayment is usually insufficient on low slope roofs. It is preferable to use an asphalt underlayment, followed by a changed bitumen product, and finally a metal product. This roof is also less frequently built due to its high cost, limited material warranty, and other factors.

Membrane with a single ply

It is a common misconception that all single ply membranes are the same. Different membranes are used in single ply membranes, and their performance varies. The key criteria for a single ply membrane are that it be waterproof, non-flammable, compliant with building codes, simple to work with and repair, pliable at various temperatures, and weldable. CPE, EPDM, Hypalon, TPO, PVC, CPA, and other membranes are commonly used.

TPO has only been used for the past ten years, so its success cannot yet be calculated. EPDM, also known as rubber, is a black single ply. Many EPDM installations have failed as a result of incorrect installation, material failure, and harsh weather conditions. The only difference between CPA and PVC in terms of properties and efficiency is the chemical composition and material viability.
