The goal of every homeowner is to build a house that will ensure the security of their family and property, for a very long time, without constantly worrying about repairs or the risk of damage. The same applies to homeowners in Media, PA too.

Only the best roofing materials and roofing contractors should be allowed to achieve this. Depending on many factors such as climate, durability, and so on, homeowners and professional roofers in any roofing company in Media, PA, have to decide which roofing materials will work effectively and the installation techniques for these materials as well.

Metal roofing and the use of Oriented Strand Boards (OSB) are two systems used in roof installation, roof repair, and roof replacement works.

What Is an Oriented Strand Board (OSB)?

An Oriented Strand Board (OSB) is a wood-derivative product formed by the joining of wood strands/flakes in definite orientations, with adhesives such as wax and synthetic resin. Although physically similar to plywood, it is structurally sturdy, more affordable, and with better water-resistant properties.

Compared to plywood, OSB does not absorb as much water, and its reaction to changes in moisture is better, too. The sturdiness of OSB is one reason why it is currently employed for sheathing in more than 70% of all walls, floors, and roofs in North America.

Building authorities such as the National Roofing Contractors Association and the Asphalt Roofing Manufacturers Association even recommend that OSB be utilized for roof decking, provided that it carries the Engineered Wood Association’s stamp of approval. Virtually all building authorities in the United States of America approve its use for roof decking.

What is Metal Roofing?

Metal roofing is a system of roofing employed by roofing contractors involving the use of metals such as copper, zinc, and steel alloys, in creating metal tiles or pieces used for roofing.

Metal roofing is one roofing system used by roofing contractors in Media, PA, due to its impermeability to water and long-lasting nature.

Can Metal Roofing Be Installed over OSB?

Some of the reasons why homeowners consider installing metal roofing over OSB are:

● Future roofing needs;

● Protection against moisture;

● Additional soundproofing.

The designs of the metal roofing systems are supposed to be airtight and water-resistant, but when installed over OSB, the risk of condensation reduces.

Before you make a decision, ensure that you consult the roofing company in Media, PA, that you will be working with to discuss the implications of this installation and how the environmental conditions in the area will affect it.

You need to ensure that the used OSB can withstand the weight of the metal. The addition of water-proof felt is done for extra protection against moisture. Remember, once OSB absorbs humidity, the absorbed humidity takes a long time to vaporize, resulting in roof leaks and damages.

Also, pay attention to ventilation in your attic to prevent condensation that will weaken the OSB. On exposure to moisture, the edges of Oriented Stranded Boards (OSB) swell, causing ridges visible under other roof coverings. Most importantly, seek the opinion of roofing experts in the manufacturing companies of these products to avoid invalidating any warranties on the purchased products.
