Plywood replacing , how to replace plywood sheathing.

The national average for wood or cedar shake roofing is between $12,000 and $16,000, or $800 per square. The anticipated life span for most wood shake roof installations is between 30 and 40 years.

Wood shake is available in a range of thicknesses, which will affect the price as well as the protection they offer. Additional treatments are available for a class C fire rating at $0.85 per square foot, and a wood shake roof will require maintenance to clean off debris before the rainy season starts to prevent mold and moss accumulating. While they are most commonly made from cedar, followed by spruce and treated pine, you can also get synthetic cedar shake like Brava Cedar Shake from Brava which have a 50-year lifespan and requires no maintenance.

Roof Tile Replacement Cost

Roof tile replacement costs between $1,400 and $1,600 per square on average for concrete tile, Spanish tile, and clay tile. Tile roofing tends to weight a lot and will cost $1,000 more if your entire roof framing needs an upgrade to support the extra weight.

Clay Tile Roof Cost

Clay roof tiles are right up there with entry-level copper in regards to price, which averages around $1,500 per square. The average cost to install a new clay tile roof costs between $15,000 and $45,000 depending on your roof size.

Concrete Roof Tile Prices

Like clay tiles, concrete tiles also carry a $1,500 per square price, with the average installation costing $22,500 to $30,000. Depending on the current structural integrity of the roof framing, it is possible some repair or strengthening work will need to be done on the rafters to support the extra weight of these heavier products.

Spanish Tile Roof Cost

Spanish roof tiles generally have a little more design to them than entry-level clay or concrete, and you can expect to pay in the region of $1,500 to $1,600 per square for the install, and around $1,000 first if your entire roof framing needs work to support the added weight.

How Often Should Your Roof Be Inspected

As your roof is constantly exposed to a variety of weather conditions, the National Roofing Contractors Association urges that your roof be inspected by a professional twice per year once in the fall, after the hot weather has dwindled down, and again in the spring, after the danger of snow and ice has subsided. Its also highly recommended that your roof be inspected after a massive storm, hurricane, or any other possibly damaging weather occurrence.

Breakdown Of The Costs To Replace A Garage Roof

Replacing a garage roof with asphalt shingles can cost between $1,000 and $2,500. However, the final bill for restoring the roof depends on whether you need to remove and install the entire roof. Additionally, replacing roofing material with a better quality covering can also impact the cost. And whether the garage is attached to your home or detached can also affect how much you will pay.

Here are the approximate costs for replacing the materials on a standard 280 sq. ft garage roof.

  • Asphalt shingles: $1,010
  • Metal garage roof: $2,250
  • Slate roof: $4,150

Suppose you need a local roofing company in Tampa Bay to remove the existing garage roof to install a new one. In that case, you should add 10% to 20% to the cost of materials. In addition, the price will be proportionally more if you have a two-car or three-car garage.

Many homes in Florida are built using asphalt shingles because they are cost-effective and have a 15 to 20-year life span. And if your home already has a shingle roof, then it makes sense to replace the garage roof with similar material.

Its good to note that garage roofs generally require replacing after 15 years. Therefore, after this time, you should regularly inspect the roof for signs of damage. If there is damage to garage roofs under ten years old, you may be able to get a roofing company to do high-quality repairs to extend the roofs life span.

5/8 inch $26.87 per sheet. This is the BEST product to use, because its very sturdy and high quality. If there is water damage it will preform significantly better than the 1/2 plywood. Note, that when you buy in bulk, the price drops to $24.18 per sheet. Bulk pricing is for at least 58 sheets or 18.5 squares. If your roof is smaller than this, you can still request the pro to buy 58 sheets, and use what is left over for other home improvement projects.

1/2 inch 24.85 per sheet. This is what most people use, and its ok quality. However, think about it this way: the difference in price between this and 5/8 is $2 per sheet or $6 per roof square.

Choosing A Trustworthy Roofer

Unless you personally know a contractor, the thought of finding a reputable company can be overwhelming, to say the least. Between horror stories of people getting blatantly ripped off, the fly-by-night crews and storm chasing contractors, it can be hard to know who you can trust.

Use these steps to find a reputable roofer:

1. Ask friends and family for recommendations.

If your friends and family dont know any good contractors they can recommend, then do some online research to identify top local contractors that seem transparent and have solid reviews across different sources.

2. Once you have a list of prospects, call them, and ask these questions:

  • Do they take on projects of your size? This one will almost always be a Yes, but it is a good starting point to get the contractors interest and attention
  • Can they supply a list of previous clients as references?
  • Are they willing to provide financial references from banks and suppliers?
  • How many other projects will they be working on while doing your roof?
  • Will they be using subcontractors? If so, how long have they worked with them?

This information will tell you how reliable they are, how much attention theyll give to your project and how smoothly the work will go.

3. From your phone conversations, choose three to four contractors to come to your home for estimates. Dont go on personality alone! Be sure to check their reputation with their past clients and/or BBB, rip off report, Angies List if you have it, etc.

Why Is Rotted Roof Decking A Problem

Most roof decking, also called sheathing, is plywood or oriented strand board . These thin sheets of wood absorb moisture when exposed to it through excess condensation or a roof leak. When sheathing is exposed to moisture frequently, there is always a chance it will decay or develop wood rot. While a single exposure to moisture is unlikely to lead to rot, routine water exposure may.

If your decking is rotting, it may or may not have developed a fungal growth that can ruin its stability by eating away at it. Whether or not there is a fungus, or just normal decay of wood due to moisture, rotting roof decking can cause several problems for your roof and your home, including:

Can I Install A New Shingle Roof Over My Existing Roof

In most states, you can install up to two layers of asphalt shingles on your roof. Roofing-over, or putting one layer of shingles over another, can save significant money on your new roof because you avoid the labor involved in removing the old shingles. Roofing-over does not have tear-off costs, lowering the projects cost by $1 to $2 a sq.ft. However, only asphalt shingles and some standing-seam metals can roof over an existing set of asphalt shingles. This makes the cost range from $6,000 to $8,000 to roof-over most 2,000 sq.ft. homes.

Roofing-over presents some issues, however. Putting one layer of shingles on another or putting metal panels over existing shingles does not address potential underlying issues with your deck or underlayment. It also doubles the thickness of your roof and means the new shingles may not lie as flat. This can result in the new shingles lifting off more easily, causing the new shingles to deteriorate more rapidly if the underlying shingles have moisture problems. The next project will require a full replacement much sooner than if you had done it all at once the first time.
