The Shingles Are Curling

Shingles can curl in two ways: There’s cupping, which happens when the edges of the shingles turn upward and there’s clawing, which is when the edges stay flat and the middle starts to come up. “Both are signs of weathering and indicate that problems potentially leaks are relatively close to fruition,” says Mark Graham, vice president of the National Roofing Contractors Association.

How much time you’ve got left: “Depending on the extent of the curling, it could be anywhere from a year to five years before you need a new roof,” says Graham.

The Pros Of Completely Replacing The Roof

  • Completely replacing the roof lasts longer than re-roofing.
  • It can be done no matter how many layers of shingles are on the roof.
  • Unlike, re-roofing that may cover up any issues with the deck, such as rot, which can eventually cause the roof to give out, a fully revamped roof addresses all issues for a safe and sturdier roof.
  • Saves more money over the long haul because it enables you to identify early signs of rot and sagging caused by water damage to the deck, which can eventually permit water to leak and drip down inside the walls where it can damage the drywall and flooring and lead to costly repairs.

Roofing over an existing roof is also called reroofing or an overlay. It is the process where roofers install a new roof over your existing one, i.e. add a new layer of shingles, which means that there is no tearing off of the old roof. It is important to know that this process can only be done once because you can only have two layers of shingles on your roof.

Roofers will teareverything off, down to the deck of the roof, and basically start from scratchwith the new roof, from putting felt paper to installing shingles. Since roofreplacement includes tearing everything off, it can be done on every roof, nomatter the number of shingle layers they are all going to be removed in anycase.

The Average Lifespan Of A Roof

Most homeowners expect their roofs to last as long as their houses. However, this will depend on the material used in the roofing. Different materials have different lifespans, so you may have to conduct a full replacement based on age alone.

Here is how the lifespan of different roofs compare

Clay/Concrete Tile Roofing

Clay/concrete tiles are very resistant and heavy. Thus, they need to be installed on top of extremely sturdy roofing reinforcement. This makes tiles one of the most durable roofing options, lasting anywhere between 50 and 100 years, longer than the average person will stay in any particular home.

Asphalt Shingles

Asphalt shingle roofs are not as sturdy as their tile counterparts, lasting an average of 15-20 years before needing replacement. However, if you pick an architectural asphalt shingle roof over a 3-tab one, you may be able to squeeze an extra ten years from them, giving you a total of around 30 years before your next replacement.

Wood Roofing

Wood shingles can last up to 50 years, but this will depend on how well you maintain your roofing. They require yearly cleanings and repainting/staining every five years because itâs easily damaged by moss and leaf accumulation. It is also a fire risk for your home, which can quickly become a reality if installed in a particularly hazardous area. As such, the average lifespan of wood shingles is 25 to 30 years.

Metal Roofing

Slate Roofing

How To Decide Between Re

If you are a homeowner with minor issues or leaks, which typically occur as the roof reaches the end of its lifespan, but the roof is in overall good shape, re-roofing may be for you.

If you only have one layer of asphalt shingles on your roof, you may also be a good candidate for re-roofing. However, if only a portion of the roof needs to be repaired, you may not want to forego re-roofing because only doing one section of the roof may cause it to be uneven in some areas, which will be noticeable.

If the roof already has at least two layers of shingles, both layers of shingles will need to be removed prior to partial re-roofing, which can increase labor costs as well as the cost for disposal. It also costs more for partial re-roofing because roofers typically charge per 10 x 10 square.

On the other hand, if your deck shows signs of major water damage, is sagging, or has large amounts of mildew or mold growth, then the deck will need to be repaired, which means you will need a complete roof overhaul.

A full roof overhaul may also be a great option for those who just want to rest soundly knowing your deck and your shingles are in pristine condition. Once the old materials are fully removed from your roof, the roofer will inspect for any signs of damage and repair any defects for a strong and sturdy roof that gives you peace of mind, as opposed to simply not knowing until it is too late, which is the risk you often take with re-roofing.

Whats The Cost Analysis Of Repairing Just Part Of A Roof

Many people opt for a partial roof repair job because they assume it will be cheaper. In fact, it will usually cost you more money, cost-per-square-foot, to repair just half of your roof rather than the entire thing.

This is because you still have to pay to get a roofing crew and all of their materials and equipment out to your site. While repairing half a roof is quicker and will take less material, youre paying more than you would for transportation and labor than you would if you just had the entire roof done at once.

In the end, if your roof needs just a few shingles replaced or a few minor patches made, you can get a roofer to make those small repairs for you. But, if you need anything more than half of your roof repaired, its in your best interest to simply re-roof your entire home. Re-roofing the home will offer you the best in quality, performance, and color consistency, and its also the more cost-effective option.

Shingles Blew Off The Roof What Caused It

We have the expectation that roofs, including its parts and accessories, are sturdy and weatherproof. That nothing can easily knock them down.

Imagine the surprise of homeowners who never expected the shingles of their roof to suddenly go missing after a particularly windy day.

Before addressing the problem, you should know why your shingles got blown off in the first play to avoid any possible repeat of this experience.

To start with, shingles are normally attached in one of two ways: either using an adhesive strip or roofing nails. Some even choose to do both.

Adhesive strips are placed on the back side of shingles, particularly at the bottom part. This part is then stacked to the upper part of the shingle below it, resulting in a tight seal for the connected shingles and it makes it harder for water to enter in-between them.

Roofing nails come with heads that are wide and flat and have short bodies with pointed ends. These nails are then hammered to the shingle and roof decking without causing damage to it.

Any of these two methods will secure your shingles. But, why do they still fail to stay put on your roof? Here are the most common reasons:

  • Installation is done incorrectly since they are poorly secured, any strong gust of wind is enough to separate a loose shingle from the roof. Nailing strips are there for a reason and unlicensed installers and DIYers often make the mistake of putting the nails above it, not on it.

What Is The Difference Between 3 Tab Shingles And Dimensional Shingles

3-tab shingles are made with three asphalt tabs on each tile. They are composed of a flat and lightweight layer, resulting in a uniform shingle. Dimensional shingles come with tabs that are available in different sizes. When they are installed, they create a more interesting layered effect. They are usually made with at least two layers, which makes them thicker and heavier compared to 3-tab shingles.

Cost Of Shingle Replacement

Most homeowners use shingles as the material for their roofing needs. No surprise there. After all, shingles are known for their durability, low cost, easy installation, and availability.

But make no mistake, having your roof shingles replaced can be costly, especially if they are made of expensive material.

Here are the factors involved in the cost of replacing roof shingles.

What Is Involved In A Roof Replacement

When to Replace a Roof

When your roof is fully replaced, the old shingles are stripped from the roof, exposing the deck. An underlayment or felt paper is then applied to the deck to help protect it from water and other elements. The new shingles are then installed on top of the underlayment or felt paper for a new roof that lasts for 20 years or more.

If the deck is severely damaged, it will need to be repaired to prevent further damage, which can eventually cause a hole underneath.

Can You Replace Shingles On Your Roof

Cut off the damage tab of the shingle with a utility knife, or remove the entire piece. Slip the new shingle or tab in place, and secure it under the shingle above with 7/8 roofing nails. Once the damaged shingle has been replaced, lift the tab up and apply a dab of roof cement to seal the shingles to the roof.

Keeping this in consideration, how much does it cost to replace a few shingles on a roof?

Most home owners spend between $300 and $1,100 for a roof repair, or an average of $650 per repair call. Typically, a job is to repair leaks. Seal the leak, replace shingles, seal the shingles. If there is a small area and few shingles being repaired, it will likely be on the low end, or as little as $150.

    BETTER/BEST: Laminated shingles

    Instead of one layer, laminated, or architectural, shingles have two or more layers with three-dimensional tabs of varying sizes. The shingles are usually the same size as the basic three tab, but a laminated shingle can weigh up to 50 percent more, which may increase durability and come with a longer warranty.

    PROS: The thicker tabs vary in size and shape for more dimension and crisper shadow lines, suggestive of wood or slate. Laminated shingles offer the greatest range of colored granules.

    CONS: More expensive than three-tab shingles.

    PRICE: $60 to over $280 per roofing square for special shapes.*

    * Shingles are priced per roofing square, which is equal to 100 square feet.

    Replace Or Repair Your Roof Nine Faqs To Consider

    Does your roof have a few damaged or missing shingles? Is there a leak? Is your roof over 10 years old? Just because answered âyesâ to any of these questions, doesnât mean that you automatically need a roof replacement. There is a roof replacement alternative! The truth is that just about any roof, regardless of its condition, can be repaired and last for many more years. Here are a few things to consider when thinking about roof replacement:

    What are those ugly black streaks on my roof?Asphalt roof shingles are not just asphalt. Although the composition changes from one manufacturer to the next, the majority are a combination of asphalt, fibrous paper, various minerals and fiberglass. Unfortunately, the mineral filler used asphalt shingles is very attractive to airborne algae spores known as gloeocapsa magma. These spores usually appear as black stains or streaks on your roof. You could spend the $11,000 or more that a roof replacement costs but still have your new roof become infested if your neighborhood has other roofs infested with algae.

    My roof has moss growing on it. Does that mean itâs too late to repair?Moss and lichens tend to grow on roofs where climates are humid and there is plenty of shade. Roof moss and lichens grow into the slots and edges of asphalt shingles, causing them to lift and making the roof more susceptible to damage and leaks.
