Replacing your roof is a major investment. Therefore, the lifespan of a flat roof is one of the main factors considered by industrial building owners. This depends, among other things, on the type of coating and maintenance.
Choosing the type of roof
The choice of membrane is the main factor that determines the lifespan and waterproofness of a flat roof. Some membranes have a longer lifespan than others. Here are the flat roof coatings that have the longest life. If you’re living in PA then contact us for Pittsburgh flat roof replacement services. Jantzi have over 10 years of experience doing this.
The multi-layer asphalt and gravel membrane
Due to lack of maintenance, this type of coating can last 15 to 20 years. However, with regular maintenance, the lifespan of a flat asphalt and gravel roof varies between 25 and 30 years.
It is exposure to the sun that contributes to reducing the life of this type of roof. UV rays make your roof brittle by causing it to lose its oils.
This causes the appearance of cracks. It is important to ensure that the gravel stays in place, as it protects the membrane. Cracks should be repaired ASAP. Contact for Roofing Restorations services now.
The elastomeric bitumen membrane
This membrane is composed of a layer of modified bitumen and a finishing layer of colored granules. It is more expensive than the asphalt and gravel membrane. However, its lifespan is longer. It is also easier to maintain.
The lifespan of an elastomeric membrane flat roof varies between 25 to 30 years. With a visual inspection in spring and fall, it can last for over 30 years.
Monolayer membranes: TPO, EPDM and PVC
Single-ply membranes offer excellent resistance to weather, fire, bacteria, and mold and air pollutants. They are also very resistant to UV rays and high temperature variations.
The materials are 100% recyclable at the end of their life. The lifespan of a single-ply membrane flat roof is 25 to 30 years.
Regular maintenance to increase the life of a flat roof
Regular maintenance is important to reduce the risk of water infiltration. It is important to carry out a visual inspection twice a year, in the fall and in the spring. This ensures that the roof is well ventilated. Learn more about leaks and water infiltration in a flat roof.
Regular maintenance also makes it possible to monitor the solidity of the structure, the integrity of the materials, the tightness of the building, the condition of the coating as well as its resistance to bad weather. Find out how to insulate a flat roof from the outside.
