What Is The Warranty On This Roof
Another thing to consider in relation to the age of the roof is whether it is still under warranty and, if so, whether that warranty is transferable. Remember that some warranties are transferable and others are not. If the roof was installed within the last few years, you shouldn’t need to invest large sums of your own money into its replacement especially not for circumstances beyond your control.
If the roof is older and out of warranty, consider the wood shingles as an attraction that might require some investment during the time that you own the property. On the upside, a roof that looks attractive with older, silvery shingles is bound to look incredible with fresh, new cedar, teak or wallaba. Furthermore, a house with older shingles might list for less, allowing you to save money that can later be invested in a new roof.
Is Osb Approved For Use In Roof Sheathing
Of course, the legality of using OSB in roof seething will vary depending on the local rules where you live.
According to the National Roofing Contractors Association and the Asphalt Roofing Manufacturers Association , the use of OSB in roof sheathing is approved as long as it meets the requirements of the APA Engineered Wood Association.
In other words, the use of the OSB in roof sheathing is approved by almost all authoritative bodies concerned with the structural integrity of roofs in the United States.
The only place where OSB isnt approved for roof sheathing in the U.S. is in Dade County, Florida.
OSB was approved for use there until 1992 when Hurricane Andrew caused significant damage to the areas rooftops.
After the devastating damages caused by the hurricane, the Dade country banned OSB for roof sheathing, claiming that it could not hold nails properly.
Although subsequent investigations and research have proven this claim false, the country maintains its ban on OSB.
In addition to the U.S., Canada also approves the use of OSB for roof sheathing as long as the panels meet the Canadian Standards Association requirements, which are based on the CSA O86 Engineering Design in Wood and CSA O325 Construction Sheathing.
Roofing Plywood Cost Per Sheet
The average cost of roofing plywood per sheet is between $70 and $100. The standard size of each sheet is 4ft x 8ft.
The price of plywood depends on the thickness of the sheet, which makes sense. When you pay for thicker plywood, you are paying for more material that promises to be more durable than thin plywood, so you will probably pay more per sheet.

Keeping this in view, does a roof need plywood?
Sometimes referred to as roof sheathing or a roof deck, this plywood acts as a foundation for the layers of underlay and the shingles on your roof and connects the roof to the frame of the house. Even though it isn’t visible, it is very important to the structure of your home.
Also Know, what thickness OSB should be used for roofing? 7/16-inch
Also to know is, is OSB better than plywood for roofing?
OSB takes longer to get wet than plywood but also takes longer to dry out. When used as a roof sheathing, this tendency to hold moisture means it can degrade faster than plywood when exposed to chronic leaks. Swollen edges have been known to telegraph visible ridges called ghost lines through asphalt roof shingles.
How thick should Roof plywood be?
Most Common ThicknessFor rafters spaced 20 or more inches apart, 1/2- or 5/8-inch plywood is recommended. The most common rafter spacing is 24 inches, and 5/8-inch plywood is recommended for that. It will support roof loads for most situations and is the standard for most roof applications.
What Types Of Plywood Are There
There are two types of plywood used in roofing construction structural and general plywood. Structural plywood has proof of strength performance provided by the supplier and indicates it has passed the building regulations to be used for structural use in a building. General plywood does not have this proof of strength performance so should not be used for structural applications. Shuttering plywood is another type of plywood but it generally isnt used in roofing. Instead, it is used to hold concrete whilst it sets.
Generally, plywood comes in 4 by 8-foot sheets, and in a variety of grades. Each side is rated A to D, with A being of the highest quality and with no imperfections or knots, which can potentially lead to weaknesses in the sheet, and D grade is generally unsanded plywood that can have defects and knotholes of up to 2.5 inches. A-grade plywood is the most costly but can be combined with D-grade plywood if the side graded D is on the underside. CDX is the most common form of plywood, with a C-grade side and D-grade side, and the X stands for the glue that bonds the sheets together. Although not made of the highest quality sheets, it is often considered the strongest due to the glue used to seal it together.

Concrete tiles are made of a mixture of sand, cement and water but they also have additional water locks on their edges that prevent any water infiltration.
CLAY TILES are produced by baking molded clay which can last up to 100 years. While concrete lasts above 60 years.
The clay tiles can come in colors ranging from shades of white, yellow, orange and brown with the Terra-Cotta as the commonly used clay color.

Is Oriented Strand Board A Viable Option For Roof Sheathing
For any material to work as a suitable option for roofing, it must meet some essential requirements. For starters, a roof sheathing material needs to be pretty durable to withstand not only the high-speed wind of the winter but also the weight of a grown adult for any projects or maintenance.
In addition to bearing the roofs load, it also needs to have a remarkable level of moisture resistance to prevent the rain from seeping or leaking into the houses main foundation, causing anything from mold to structural weakness with time.
As previously discussed, OSB is made from the compression of durable types of wood like aspen and poplar. This means that with the proper thickness, such boards are capable of bearing heavy loads.
Additionally, since the flakes of the wood are mixed with a waterproof resin, it has some waterproof properties that allow it to resist varying degrees of moisture.
Based on all that, we can conclude that Oriented Strand Boards qualify as a viable roof sheathing material.
The material is so durable and strong that its currently used as the material for roof sheathing in anywhere between 60 to 75% of all roof sheathings and walls and floors in North America.

-
Colonial. Green or dark gray
-
Farmhouse. Green or natural colors
-
Craftsman. Brown or other neutral colors
-
Victorian. Gray or green
-
Ranch or split-level. Any color that contrasts with the home’s siding

How To Avoid Roof Deck Problems
Roof decking problems cannot be avoided but they can be reduced or eliminated. Moisture absorption is the prime culprit for roof damage. It is where all roof failure begins. When moisture penetrates wood surface, the panels would start swelling. Moisture buildup could only be prevented if deck installation keeps the wood movement from happening and when buckling is avoided. Through this, moisture has no place to enter unless the underlayment and the roof tiles have been compromised.
Additional tip: keep the wood panels dry by immediately installing the underlayment. The longer the decks are exposed to the weather, the more they become the first target of heat and rain.
For what type of wood you need for your roof mainly depends on all the different roofing materials you need for your home, your location and the weather, and local and building codes. For more helpful and specific information, call your reliable roofing contractor. At Birmingham Roofers, they can help you in deciding for the best wood panels used for roof decks.

What Type Of Wood Is Best For Roofing
To most builders, plywood is the best wood for roofing. Plywood offers special benefits to buildings. Plywood is water-resistant and less expensive. It maintains its structure for a long time.
Nevertheless, other builders go for OSB . It is a more recent wood for roofing. It costs lesser. OSB is specifically selected for roof sheathing. These two types of woods are most preferred by builders for their cost and overall availability.

Plywood Vs Oriented Strand Board
Strand Board is gaining popularity as a material used for roofing. OSB is a type of wood made up of strands in varying orientations compressed together with adhesive to form a board. This type of wood is typically a cheaper alternative to plywood, but it meets most standards of its alternative.
There are a few disadvantages to using this cheaper alternative to plywood. The most notable ones are the inability of OSB to hold nails as effectively as plywood.
This means that the structure of the roof is compromised ever so slightly. The second disadvantage is the way OSB absorbs moisture.
While it is true that OSB takes a longer time to absorb moisture than plywood, it also takes that much longer to dry.
While plywood dries down evenly, OSB tends to absorb moisture more around the edges, making it swell and dry down with a ring around the edges.
Florida Dade County has prohibited the use of OSB for roof decks because of the effects that Hurricane Andrew had on homes that used the material for roofing.
What Kind Of Plywood For The Roof
When it comes to choosing what kind of plywood you need for the roof, it is important to understand the basic categories that you can choose from. Most construction sites will consider the use of either OSB or plywood for the roof.
CDX plywood is a construction-grade type of plywood that is designed for exposure to the elements. It can withstand moisture for a brief period of time but may become warped and delaminated with consistent exposure to the elements. This particular type of plywood is crafted from layers of wood stacked on top of one another with alternating grain patterns in each layer. The alternating grain gives the plywood a system of checks and balances that allow it to expand and contract evenly across the sheet.
Here is another option for plywood you might think about: RTD Plywood: Everything You Need to Know
Alternatively, OSB is created from wood chips, resin, and adhesive that is baked and formed into the shape of a sheet of plywood. It is extremely resistant to moisture. However, when it is penetrated by water, it takes a very long time to finally dry out compared to CDX plywood. The edges may also swell during this time, creating small yet visible ridges on the roof where the boards meet.

Standing Seam Metal Roofing
The most common type of metal roof is the standing seam roof, so named because the aluminum or steel roofing panels meet in raised seams that interlock to keep moisture out. Metal roofs of all kinds are increasingly popular in regions with heavy snowfall or where there is a notable danger of wild fires since this is a roofing material that is fully fireproof.
Metal roofs are very long-lived and are fully recyclable when they finally do wear out. But installation requires special skills and not every roofing company is prepared to install a standing seam metal roof.
Costs typically run from $6 to $12 per square foot, installed. Metal roofs commonly last 30 to 50 years, but some have been known to last 75 years.
Types Of Roof Sheathing Examined
Roof sheathing, also known as roof decking, is the surface that roofing materials attach to.
These materials can be wood shakes or asphalt shingles. Roof sheathing is commonly made from materials such as:
- Planks
- Compressed wood panels
- OSB
Each one of these materials have also been categorized as exposure or exterior grade in order to be used as sheathing.
This also means that they are able to withstand any precipitation that may fall while the roof is under construction.
However, it is important to note that there are some sheathing materials that are made from concrete and steel.
Although not all roof sheathing is created the same, there are several different types that are currently being used in the construction industry.
Concrete Sheathing
This type of sheathing is used by roofing contractors when there is a need for high levels of strength and support for the roof.
It is also used as fireproofing material.
Concrete is also becoming a major material being used in eco-friendly and green buildings.
Concrete sheathing is typically poured into several forms or set on a roof in a pre-cast board. When it is poured, it is reinforced with bars.
Concrete sheathing is considered low maintenance because it is easy to clean, and it helps reduce the chances of the roof sustaining wind damage.
Oriented Strand Board Decks

What Is The Best Plywood For Roofing
Plywood is most often used for roofing. Plywood is used almost in exterior and interior construction applications. Builders like to use plywood, due to its structure stability, water resistance, and low cost, and other excellent properties.
There are many different types of roofing materials that are available in markets such as Metal roofing, Stone-coated steel, Rubber slate, Solar tiles, Asphalt shingles, Green roofs, and more.
How Old Is The Roof
With any home that becomes a serious purchase prospect, you should ask about the origins of the key features of the property. If the roof consists of wood shakes or shingles, one of the most pertinent pieces of information concerns the roofing installation date. Simply put, was the roof installed within the last five to 10 years or does it date back 25 years or more?
If the roof was installed within the last decade, you can most likely count on the roof lasting through your occupancy of the property that is, if you are like most homeowners who only occupy a given address for eight to 15 years. If, on the other hand, the roof was installed more than 20 years ago, the shingles might require a full or partial replacement during the time that you own the property.
Then again, the longevity of the roof will partially depend on the quality of the wood and the effort you make as a homeowner to maintain the roof. As long as your neighborhood is not hit by some cataclysmic event, you could make a 20-year-old roof last an additional 15 to 25 years or perhaps longer.
