Roofing Over An Existing Roof: What You Need To Know
When you start noticing issues with your roof, or when it is nearing the end of its lifespan, it is probably time for some big decisions. You may wonder about the roofing options you have, and which one will be the best solution for you. The best thing to do then is to call in a professional roofer and discuss it with them, as they have both the needed expertise and experience to steer you in the right direction.
If the condition of your roof is such that a fewrepairs will not suffice to get it back into shape, but it is still functionalenough that it doesnt need to be completely torn off and replaced, then youshould think about reroofing, i.e. installing a new roof over your existingone. Reroofing is not the same as roof replacement and there are certainconditions that your roof needs to satisfy in order to be a viable candidatefor reroofing.
Keep reading to find out all you need to know aboutreroofing, including how it differs from a roof replacement and what its mainadvantages are.
When Do I Put New Shingles Over An Existing Roof
When you look for a roof improvement or your roof starts to fail, but its underlying structures and wooden deck are in a generally good condition, a reroofing might be the best choice for you. It means that your shingles may be losing granules and are worn out due to age or weather, but they are not causing leaks, they are not curling or missing. These are all good conditions for installing a new layer of new shingles over the existing layer.
Reroofing can also be done when you simply want or need a change. If you are completely renovating your home and your roof needs to match the new style, adding a different design or color to your roof can completely mix up the look and feel of your home. Installing a new shingle layer will give your roof depth and even a three-dimensional appearance, as it is slightly raised due to the existing layer of shingles beneath. The best IKO shingles for this are the Cambridge Xtreme 9,5° or Cambridge Xpress.
When Should I See A Doctor Because Of The Side Effects I Experience From Shingrix
Shingrix causes a strong response in your immune system, so it may produce short-term side effects. These side effects can be uncomfortable, but they are expected and usually go away on their own in 2 or 3 days. You may choose to take over-the-counter pain medicine such as ibuprofen or acetaminophen. Contact your healthcare provider if the symptoms are not improving or if they are getting worse.
In clinical trials, Shingrix was not associated with serious adverse events. In fact, serious side effects from vaccines are extremely rare. For example, for every 1 million doses of a vaccine given, only one or two people might have a severe allergic reaction. Signs of an allergic reaction happen within minutes or hours after vaccination and include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness. If you experience these or any other life-threatening symptoms, see a doctor right away.

Natural Remedies For Shingles
If you had chickenpox as a child, the shingles virus lies dormant in your body. The virus can reactivate later in life and cause a shingles rash. The rash can occur on any part of your body but typically only affects small sections.
Pain is usually the first symptom of shingles. The rash and fluid-filled blisters form within a couple of days after the onset of pain. Some people with shingles also have a fever, sensitivity to light, and fatigue.
According to the Centers for Disease Control and Prevention , about 1 in 3 people in the United States will develop shingles at some point in their lifetime.
The shingles virus can last between two and six weeks. Shingles isnt life-threatening, but some people experience postherpetic neuralgia. This is when nerve fibers become damaged, causing shingles pain that lasts for weeks or months after the rash clears.
Theres no cure for shingles, but your doctor can prescribe antiviral medication to help shorten the duration of the virus and reduce symptoms.
Although an antiviral is an effective treatment for shingles, its not the only option. Several natural remedies may also reduce pain and discomfort.
Dry your body completely and then wash your towel to avoid spreading the virus to others.

Your Roof Is Curling And Shingles Are Misshapen
If your shingles are curling or misshapen, it will do more harm than good to shingle over old shingles. The roofs surface must be flat, or water can get underneath the shingles. Covering curled or damaged shingles will only trap that moisture. By not having the roof properly repaired, you may set yourself up for leaks.
You Want A Different Design Or Color
Maybe you are renovating your entire home, and you would like your roof to match. Or, perhaps you just want to give your home better curb appeal.
Often, homeowners will update and upgrade their homes when they are trying to sell them quickly. If it is your forever home, a different design may be part of your plan as you work to complete your vision.
In either case, it may be possible to layer a new color over your current shingles for less time and money.
Why Install A Layover
If its basically only a new roof that would accommodate a layover, it begs the question, Why install a layover? It doesnt take that much time or labor to remove the first layer of shingles that a layover gets your roofing project done faster or cheaper. In fact, a layover would only take longer because there are literally more factors to take into consideration since you have to think about everything you thought about to install your first layer of shingles plus your first layer of shingles.
New Roof Material Installed Over Existing Shingle
When installing a new roof, removing the old roofing materials can be messy and time consuming. However, if you have a current asphalt shingle roof and are looking to replace it with similar product, you may have an easier option to consider installing new material directly on top of the old surface.
While re-shingling over an existing roof is possible, a few conditions must be met. But first lets consider why we would want to layer over existing shingle.

Though a common misunderstanding, adding more layers will not make your roof waterproof. Your underlayment is what protects it from water, and if that needs replacing, the whole roof does.

Taking Care Of Your New Roof

Season after season, you want to ensure that there is no storm damage you cant see from the ground. You also want to find out right away if a warranty claim is ever necessary.Your roofer can also perform seasonal maintenance to extend the life of your new roof. Occasional cleaning removes debris, moss growth and algae buildup. Replacing missing or broken shingles prevents minor issues from becoming major ones.

The Contractor Cant Inspect Your Asphalt Roofs Decking
When you get a full roof replacement, your roof is taken down to its decking. This gives your contractor a chance to inspect the deckings integrity to see if it can handle your new roof.
When you get a nail-over, theres no opportunity to inspect the decking before installing your new roof. If one of the boards break during installation, the contractor will have to take off the old shingles, replace the piece of broken decking, put the old shingles back on, and start installing again.
This adds to the time it takes to replace your roof and can even add to the final cost of the job.
Home Remedies And Lifestyle
In addition to triggering an uncomfortable rash, shingles can cause symptoms that are similar to those of other viral infections.
While prescription and over-the-counter drugs can help, one of the most important things you can do while dealing with the illness is to take good care of yourself. If youre caring for someone else who has shingles, creature comforts can be enormously soothing.

Why Does Shingles Appear Mostly On One Side Or In One Area Of Your Body
The virus travels in specific nerves, so you will often see shingles occur in a band on one side of your body. This band corresponds to the area where the nerve transmits signals. The shingles rash stays somewhat localized to an area. It doesnt spread over your whole body. Your torso is a common area, as is your face.

Should Old Shingles Be Removed
The importance of having a proper roof over your head is to provide shelter, but an adequate roof goes ahead to also protect the overall building from damage. Roofs get old, and when they do, a replacement should be on the offing.
Because reroofing is not a foreign idea, many may choose to take that route, but if you are still undecided, here are reasons why tearing off the existing roof before installing a brand new one is good:
The advantage of tearing off a damaged roof is that your new roof will benefit from a proper installment.
When the old roof is out of the way, the new top starts from scratch and has the potential of being laid on a flat surface with no obstructions therefore, it will be firmly attached, and the entire roof will have an even surface.
The biggest reason behind reroofing is that homeowners have this fancy idea that they aresaving money in labor, shortening the time needed to complete the project, and finding it easy to manage the roof replacement process.
The truth is that reroofing is a bad idea because the layers of roofing materials stalked on top of each other will need to be dismantled at the end of the day. The homeowner will pay more money to have it torn apart as it will involve more than tearing off one layer after another.
Overall, reroofing in the name of cost management is just a delay tactic.

How Is Shingles Diagnosed And Treated
If you think you might have shingles, talk to your doctor as soon as possible. Its important to see your doctor no later than three days after the rash starts.

If you have a condition that weakens the immune system, your doctor may order a shingles test. Although there is no cure for shingles, early treatment with antiviral medications can help the blisters clear up faster and limit severe pain. Shingles can often be treated at home.

How Many Times Can You Shingle Over A Roof
As much as the Building Code and City Code allow reroofing as an accepted way of roof replacement, it limits the number of overlays to only 2. You are required to tear the roof down to the decking and replace it with new roofing materials.
That aside, some homes have dared the roofing requirement by laying new shingles on top of another four times, which is wrong and very dangerous.
If you must, use the highest quality of asphalt roofing material to carry out a reroof. High-quality asphalt is slightly lighter in weight than other roofing materials such as wood, rubber, and metal shingles.

How Long It Would Take To Install A Layover
The same factors that influence how long it would take to install a layover are the ones that influence how long it would take to do a full replace.
Pitch: Pitch is a measure of how steep your roof is. The steeper your roof the longer it will take to install your layover because of safety concerns. This would be especially the case with an older roof because the crew would be walking on damaged shingles. A potential reason a layover wouldnt be possible!
Complexity: It takes more time to install a layover on a complex roof. Each part of the roof is known as a facet. The typical A-Frame roof has two facets: one on each side of your home. A complex roof is aesthetically very appealing, and it would be somewhat of a waste to do a layover since the second layer of shingles wont lay flat, wont look the same as the first layer, and will be more prone to curling, peeling, and blow offs, all of which will make your roof look less nice.
Flashing: Anyplace that breaks up the contagious nature of roofing material is a place where youll find flashing galvanized steel or aluminum that prevents water damage. If roof protrusions and the areas where the roof meets walls are what inspired the need for flashing, then you can only imagine how much more vulnerable to water damage your roof will be given that a layover will cause more protrusions. After all, youre literally creating more protrusions and more points of contact between your roof and wall!
