Plywood Repair for Roofing

There you are in the attic putting away another box of stuff. You don’t know what to do with it, so for now it goes in the attic until you figure out what to do with it. You happen to look up and you notice the bottom side of the plywood decking is discolored from water stain and some of it is rotting. How bad is this? And what should I do about it?

There are a number of reasons how the plywood could have gotten wet. A thunder storm with high winds may have loosened some of the shingles and allowed rain to be blown up under the shingles.  A tree limb may have fallen on the roof causing damage to the shingles and decking. Or the roof may have just gotten old and deteriorated. It may have simply reached its life span.  Unfortunately all of these reasons lead to a costly roofing repair job.

To repair the damaged plywood ( or OSB ) you must first determine how much of the plywood is damaged, and how much that you want replace. Be sure you plan to replace all the damaged plywood. Otherwise you will probably be repeating your repair job again as the part of the plywood that you didn’t replace continues to rot. Remove the shingles in the damaged area by lifting one shingle at a time and rocking it back and forth while pulling down until it releases. You will have to determine how many shingles you need to remove in order to replace however much of the plywood you want to remove and replace.

Next you will need to remove the nails with a pry bar. There will be some nails under the top row of shingles that you will need to gently remove without damaging them.  A flat pry flat pry bar should be used rather than a hammer. Next remove the underlayment. The underlayment should be easily removed since it is being held down by only a few nails with plastic caps.

Now you are ready to remove the old damaged plywood. Remove the nails holding the plywood in place with a hammer and pry bar. Being careful not to loose your footing lift the old plywood out and place it safely away from your work area. Next cut your new plywood, if necessary, to fit the opening and securely nail it down. Once the plywood has been installed replace your underlayment using roofing nails with nail caps.

Now it’s time to replace your shingles. Start at the bottom and work your way up fitting each shingle in place covering up the row of nails below it. Use 6 nails per shingles to insure the shingle will hold. The last row of old shingles will need to be held up so the last row of new shingles will fit up under them. Once the last row of new shingles has been nailed down apply a dab of roofing caulk over each nail and then lay old shingles back down over them.

And there you are. A job well done. Now get back to filling that attic up with more stuff.

Asphalt Shingle Recycle

Recycle Asphalt Shingles

Is there anything we don’t recycle?

We even recycle old songs, old television programs, and old movies. Songs like; “Come Together” by the Beatles in 1969 and recycled by Areosmith in 1991, or “I Wish” by Stevie Wonder in 1976 and recycled by Lady Gaga in 2015. And how about television programs like “Full House” first aired in 1987 and recycled as a continuation sequel under the name of “Fuller House” in 2016. Then there are movies like; “You’ve Got Mail” released in 1998 was loosely based on 1940’s movie “The Bookstore Around the Corner” with James Stewart.  “Pride and Prejudice” has been recycled 6 times, “The Longest Yard” 5 times, “The Hulk” 4 times, “King Kong” 3 times, “Godzilla” and there’s more but I’ll spare you the stats.

Environmental Roofing Recycling

Recycling is not a bad thing. In this age of protecting our environment almost everything is recycled. So is not surprising that eventually asphalt shingles would find their place in the recycling industry. It is not unusual during severe weather outbreaks throughout the country that thousands of home and business roofs are damaged from large hail each year.  When this occurs all those homes and businesses must have their roofs replaced. That means the old roofing materials have to be removed and discarded. In America eighty percent of all homes are roofed with asphalt shingles.

The shingles removed from the average American home weighs from one to three tons. Every year millions of tons of asphalt shingles are dumped as waste material. Previously all of those old roofing materials were sent to landfills. So it’s not hard to see the need to recycle such an enormous amount of asphalt shingle waste material.

Shingle recycling is becoming more and more common in order to keep asphalt shingles and similar roofing materials from ending up in America’s landfills. Recycling asphalt shingles contributes to keeping our country environmentally clean.  Asphalt shingles cannot be incinerated to destroy it due to its petroleum qualities.

These recycled shingles have become a valuable commodity when converted into material used for paving America’s roads and highways. They are converted into Hot Mix for paving highways and roads, and Hot Patch for repairing potholes. The recycling industry is hoping to find energy saving products that are environmentally safe that can be introduced to the public at an affordable price.

Uses for Recycled Shingles

There are other potential uses for recycled shingles may be used in patio decking, pool patios, sidewalks, and even interlocking bricks. Recycled shingles products are found in ground cover material, ground up and used on parking lots, driveways, and walk ways.  Because asphalt shingle are a refined petroleum product they can be recycled to produce a non-renewable resource in the form of oil. Only time will tell all the uses that may be derived from recycled shingles.

For now it is safe to say we are headed in a direction that if it can safely be recycled it will be recycled.
