Foam Roofing

Nowadays commercial roofing system is increasing its popularity. The Dura foam roof system has roofs which have rigid and durable surface. Its thick closed cell polyurethane waterproofing barrier prevents leakage. It is the only roofing system which has no seams. This SPF roofing has been integrated into the elastomeric roof coating system in various ways.

It is either used with one coat of a roof coating product or with a base coat of roof coating product. Sometimes two layers of top coat roof coating product system are also used.

This makes the roof more powerful and potent as it is made out of many layers of fully adhered, monolithic roof coating and spray foam product.

Pros of foam roofs

  •    The foam roofs have great tensile strength. The durability is high in comparison to that offered by a multi-layered built-up roof system.
  •    The reflective top coat of the roof reduces the cooling costs and the SPF insulation technology which keeps heat trapped inside.
  •    Product lifecycle is more than 40 years. If the roof is properly maintained and the insulation of the foam is protected constantly by using roof coatings, then it will last for long.
  • They are completely waterproof and seamless and hence provide fully adhered roofing protection to the roofs on which these products are applied.
  • It has huge wind resistance and the building structural support also gets enhanced due to many layers of coating product and SPF application.
  • The potential for water travel throughout the roof system is virtually eliminated. If any puncture is caused in the roof by hail or any other foreign objects, then it remains at the place where it is affected.
  • It is quite easier to apply SPF insulation around protrusions like flashings and around angles against the curbs.

Cons of Foam Roofs

Along with the pros, it is always important to know the cons. Only when you know the cons of a product and find out the reason of that cons then you can tackle the reason for eliminating the con completely. Some of the cons are:

  • Experts hands are required for application of foam roofs as it has rigorous specifications.
  • It takes a lot of time to master this highly specialized system of roofing.
  • Sometimes special training is required for the contractor to put down the foam correctly.
  • It is initially costlier than another roofing system though it is beneficial in the long run as it is durable for long.

It is essential that once the spray foam has been applied as the base layer, the top layers are applied within 2-12 hours. Ideally, the application must be done on the same day when the foam application is done. There is a granular coating product which can be combined with coating products for preventing the damage caused by birds pecking. This shows that the majority of cons of foam roofs can be tackled easily by simple methods.

Features of foam roofs

  1. As the foam roofs are lightweight, durable and seamless so it is used around roof penetrations such as pipes, vents, and edges. It is useful at the places where there is an impenetrable wedge, keeping these penetrations high and dry. Along with that, it could be applied on the roof surface in the ponding areas for preventing heavy standing water. It will improve drainage and result in superior leak protection.
  2. Dura foam roof are renewable so they are known as a green roof system. This roof system not only saves energy but also never wear out. As long as the upper coating layer is maintained, the roof will last for long. Hence, proper maintenance of this roofing system helps to have savings of over 75% by never roofing it again.
  3. SPF is the best insulator you can buy and there is closed cell SPF which is an insulating material that does not soak up water. Since it is manufactured on the roof surface so there is need of qualified installation to assure material integrity.
  4. Usually, these roofs come with warranty. When you plan to use dura-foam then make sure that it includes a leak-proof warranty. There is a need for affordable long-term service for ensuring that the roof continues to last.


SPF roofs last for long and hold insulation value forever. They can bear extraordinary weather conditions that’s why they are preferable. When the cost is compared then it is more economical than other roofing systems as these roofs are durable and last for long. If you want to install new penetration, then it could be done easily. The new additions become part of the warranted roofing system. With the increase of the cost of the energy, the demand for SPF roofs is also increasing. It is useful for construction industry for providing roof stabilization.
