Rv And Travel Trailer Roof Replacement Cost

4 Reasons Plywood and lumber prices are high @Roofing Insights

The cost to replace the roof on an RV or travel trailer averages $7,000 to $12,000. RVs and travel trailers have flat roofs. Therefore, they typically use a flat roofing material. However, it is applied differently than on a home. The RV is typically taken to a shop for this project, and the costs are usually charged by the linear foot rather than by the square. This is an expensive process and usually involves a full replacement, including the roofing material and the under material.

Average Cost To Tear Off And Replace A Roof

The average cost to tear off and replace a roof is around $7,000 to $24,000. This breaks down to roughly 60% of the costs in labor and 40% in material. The tear-off costs around $100 to $200 a square, depending on the pitch and material. The installation costs $150 to $500 a square, depending on the material and pitch. The roofing material averages $100 to $1,200 a square for most asphalt and architectural shingles, some tiles, and the most common metals. Shakes, slate, and clay tiles cost more in materials.

What Size Of Plywood Does Your Roof Need

The plywood thickness your roof requires depends on the load that the roof will need to be able to handle. If you have a flat roof, it will have a heavy load so you will need a thick plywood. By comparison, a pitched roof handles a lighter load as the weight gets evenly spread across the roof, so the plywood can be thinner.

Some older homes have -inch thickness but this is not the norm because its a bit too fragile. You therefore will have to settle for plywood thickness thats between ½ and inch thickness, both of which are suitable for standard loads with roof rafters being placed 24 inches apart.

Should You Choose ½-inch or -inch Roof Decking?

These are the most common thicknesses for roof decking, so you might wonder which one you should use and if it even matters. Basically, plywood thats -inch decking is stronger and more durable than ½-inch decking because of its extra thickness. It also produces a smoother finish as it hides any valleys between joists and trusses.

But, it takes more time and money to install. Its a good choice if your home is susceptible to hurricanes, a lot of snowfall, or other extreme weather conditions, because its thicker and therefore more protective.

Factors Increasing Plywood Prices

There are many factors that affect plywood prices.

  • Demand and supply.

if there is high demand for construction materials, then people will be more willing to pay a higher price because they need this product badly.

If the supply of such material exceeds its needs, however, the prices would go down as it becomes available at a cheaper price.

  • Demand for materials used in plywood production.

Lumber prices may also affect plywood prices, as wood is one of the main ingredients in making plywood however, there are other factors such as demand and production that will further increase or decrease its overall cost.

Plywood manufacturing requires lumbers of different wood- not to mention, that these are not available in all countries. Some countries may grow superior quality wood and others not.

For example, in Oak, maple, and walnut, there is a shortage of these wood species which results in. Plywoods of these materials cost higher and are knowns as high-grade plywoods. Eventually costs more than other regular plywoods.

  • So If the demand for this material goes up due to a high need in another industry or country, then its cost would also go up accordingly. This will increase the overall cost of manufacturing wood products that use it as an ingredient.
  • The weather is also a factor that affects plywood prices

if there are good rains, then the supply of lumber would increase which will make it cheaper to produce wood products like plywood.

Questionable Practices At The Estimate Stage

What Size Plywood Do You Use On A Roof

These kinds of add-ons, after the repair job has begun, are unfortunately commonplace. To be sure of getting the job, some contractors employ the devious practice of submitting an incomplete estimateand therefore quoting a lower price than their competitors. The customer is then hit with a string of extras.

How much should you actually pay to service or completely replace roof sheathing material? Plywood isn’t too expensive. Usually, the prices depend on the manufacturer’s factory rates. Most distributors add their transport and distribution figures that raise the cost effectively.

Some other issues can raise the price of roof sheathing material repair or replacement. Rotten decking will require additional labor to completely tear off the roof material and plywood and replace it with fresh plywood. Inadequate decking is the plywood thickness isn’t enough and may not be enough to carry the asphalt shingle or dense metal material such as standing seam metal’s weight. Modernize has a great estimate on figures you’ll need to spend on replacing roof decking.

Roof Sheathing And Replacement Costs

A roof stripped down to the very basics comprises a frame resting on walls, and a covering over it to complete the building envelope. There are many different types of covering materials available, although their suitability depends on the pitch of the roof and the support work below.

Thatch, for example requires a steep pitch, but only a simple framework to support it. Smaller tiles in a wide range of materials however require more complex support work. For this reason, roofers prefer to replace like for like. Shingle tiles became a popular form of roof sheathing in the early 20th century although not all shingles are the same.

Roof Replacement Cost By Material

The material has a tremendous impact on the total cost of the materials and labor. Some materials are exclusive to the roof type you have. For example, a flat-topped home uses specific materials that are not used on conventional slopes. However, most homes use asphalt shingles, metal panels, tiles or shakes made of several materials, or specialty materials like cedar or slate.

Each material has costs. The more features a material has, the higher its costs. For example, architectural shingles that help protect against hail damage have a higher cost than standard architectural shingles. Clay tiles cost more than concrete, while copper costs considerably more than aluminum. Rare materials like slate and copper cost more due to their availability. Materials that are harder to install, such as wood and some clay tiles, also have higher costs. Materials with additional benefits, such as energy efficiency, algae protection, hail protection, or rainwater management, also have higher costs.

When choosing a material, consider its costs, maintenance, and longevity. While slate is very expensive, it can last 200 years or more in the right circumstances with little maintenance. This can make it more of an investment than a less expensive material.

Dont know your roofs square footage? Dont worry its easy to calculate an estimate. Though different types of roofs will take more or less materials to cover, you can assume as a general rule that your roof will be about 1.5 times the size of your homes square footage.

You can get a close guess of your roofs square footage with this formula:

  • Home square footage x 1.5 = Roof square footage

When you are planning to build a new roof or rebuild an existing roof, you will want to have an idea of how much material youll need to cover that roof. If sheathing the roof with plywood, there are basic formulas for roughly estimating the number of 4 foot by 8 foot sheets of plywood you will need to cover your roof.

  • Measure the length and width in feet of each roof slope with the tape measure. A typical gable roof will have identical slopes on each side of the ridge line. Multiply the length by the width to find the square foot area of one slope. Multiply that figure by 2 to get the total roof area. For instance, if the slope length is 40 feet and its width is 20 feet, 40 multiplied by 20 gives 800 square feet. Since there are two identical slopes, multiply 800 by 2 to get a total roof area of 1,600 square feet.

  • Divide the total roof area by 32 to get the number of sheets you will need to cover the roof. A typical 4 foot by 8 foot sheet of plywood covers 32 square feet. If your roof area is 1,600 square feet, 1,600 divided by 32 will mean you need about 50 sheets to cover the roof. Add 10 percent to allow for waste.
