How to Know if There's A Roof Replacement on Your New Home!

Date: April 26, 2022

It’s not simply the shingles you see from the street that makes up your roof. A complete roof system comprises a variety of different roofing materials and components.

To keep you and your loved ones safe from the weather, every section of your roof plays a critical role. Your decking and flashing, for example, do not need to be changed.

When you get a new roof, you have to eliminate almost all of your old roofing materials and accessories.

When you’re done reading this, you’ll have a comprehensive understanding of your roof’s anatomy and the key signs to look out for a roof replacement.  

The Components of a Roof:

1. Roof decking 

The hardwood planks that make up your roof’s structure are decking. Installing your roof’s shingles and other elements begins with these planks.

Roof decking may need to be changed when a roof is replaced. If your roof requires replacement, you won’t know for sure until the old one is removed.

Your roofing contractor will have to repair any rotten boards they uncover before they can begin installing your roofing materials.

2. Roof flashing

Your shingles are protected from the elements by a layer of metal called roof flashing when they contact anything like a wall or chimney. If you acquire an asphalt roof, you won’t necessarily have to repair your flashing.

A roof replacement is not necessary if the metal in your flashing remains intact and free of corrosion. Roof flashing must be changed if broken, corroded, or if you’re switching from a 3-tab to a dimensional asphalt shingle.

3. Underlayment

You may use underlayment to protect your decking by covering it with felt (15 lb, 30 lb, or synthetic) material. It is essential that you incorporate the installation of new underlayment as part of your roof replacement.

Remember that your underlayment is the final line of protection for your decking in your roofing system.

4. Drip edge

The drip edge is a metal flashing fitted around your roof’s margins to keep water away from your fascia and other roofing components.

When installing a new asphalt roof, the drip edge must be changed. Having it on your roof serves as a code for intrusion detection. You may be penalized if the system isn’t built correctly during a home inspection.

If you select a contractor who skimps on the drip edge installation, you’ll have to address the problem before listing your house for sale if you don’t want this to happen to you.

5. Ice and water shield

To keep water flowing down your roof in the correct direction, you need to have correctly functioning roof valleys. The steady flow of water every time it rains necessitates the deployment of a barrier.

When protecting your roof against ice and water damage, you’ll want to utilize Ice and Water Shield.

A new roof replacement will need the installation of ice and water around your roof penetrations and in the valleys of your roofs. During routine roof care, keep the valleys free of any debris.

Water will pool on your shingles or soak through the shield, eventually reaching the decking underneath and creating leaks.

6. Asphalt shingles

The shingles can be seen on the outside of your roof and are one of the main things people think about a new roof.

As a result, you may be sure that any roof replacement will contain shingles. Keep in mind that proper roofing procedures must be used while installing your shingles.

7. Ridge capping 

At the point where two slopes of a roof meet, ridge capping is the trim to finish the look. Their pre-bent shape allows them to conform to your roof’s ridges, making them thicker than standard shingles.

During a roof replacement, the ridge capping must be rebuilt. It’s important to know that some roofing contractors attempt to minimize expenses by using 3-tab asphalt shingles as ridge capping.

One of the most frequent roof leaks may be caused by using these. To ensure that you’re obtaining the correct ridge capping for your roof, you should always review your estimate with your contractor before signing it.

8. Roof vents

Your roof’s lifespan will be severely shortened if it does not have enough attic ventilation to remove the accumulated hot and cold air.

In other words, if you’re replacing your roof, you’ll also be getting new vents for it. It’s entirely up to you whether or not you want to stick with the current kind of vents or switch to something different.

This essay on the significance of appropriate attic ventilation might help you better understand your vent choices and how they influence your roof.

9. Pipe boots

To stop water dripping into your house, you must cover your roof’s pipes. To help with this, pipe boots are a must-have. When installed around your roof’s penetrations, pipe boots prevent water seeping in. Getting a new asphalt roof necessitates the replacement of these.

One of the most typical leaks a roofing contractor encounters is the damaged pipe boot. Regular inspection of your pipe boots as part of your roof maintenance is thus very essential.

What Does the Roof Replacement Process Look Like?

When you have an asphalt roof replacement, you’ll have to replace most of your roof system’s parts and accessories. However, if your deck and flashing are still in excellent shape, you may not need to replace them.

Finding Out the Age of Your Roof

If your shingles are broken or raised this is usually a sign that you need a roof replacement

If you haven’t constructed your house from the start, you’ll need to determine how old your roof is before making any repairs.

Aside from helping you prepare for a new roof, knowing how old your old one is will help you foresee issues and what you can do to avoid them in the future.

Determine the age of your roof with these objectives in mind.

1. Ask the previous owners

It would be best if you didn’t shut off all communication with the previous owners after closing on your house and moving in.  Asking about the house’s condition, such as how long ago it was last re-roofed, is something that most homeowners are happy to help with.

You don’t have to hire a lawyer to inquire about these matters. A long-time home resident is likely to know the exact date when the existing roof was put on.

2. Find the building permit

Enquire with your local building department to see whether a permit is required for new roof installations.

If this is the case, you may get a copy of the permission by contacting the county administration. This will provide you with the precise date the roof was built and is one of the most reliable sources of information.

3. A roof replacement receipt should be provided

The previous owners may remember the roofing firm that renovated the roof. It’s possible, though, that they’ve already lost their receipt.

As long as you know who owns the company, you can request a copy of the receipt from them, or you may ask for it from the prior owner. It’s common for roofing companies to keep track of all their work.

4. Free estimations from a house inspector or a roofer.

A house inspector might be hired if everything else fails to determine the roof’s condition and estimate its age.

Such experts have a great deal of experience in their specialty. Whether you ask them, they’ll be able to tell you right away if you’re showing indications of old age.

A roofing firm can provide the same level of service. The impartiality of a house inspector, who does not have a product to promote, will likely be better than that of an expert sent by a firm that installs roofs.

Do I Need A Roof Replacement?

It is possible to replace a worn or damaged roof with a new one. Even though the roof is more than 25 years old, it does not need to be changed. However, some key signs indicate that your roof is beyond repair, signs that signal that you need a new roof. They include:

Curled Shingles:

Several factors contribute to curled shingles, including high winds, prolonged exposure to heat, and time.

The shingles on your roof cannot do their job correctly if they’ve curled, so they must be changed to preserve your roof.

Missing Shingles:

When shingles fall off the roof, it’s a sure indicator that the glue holding them in place has failed.

After a certain amount of time, this is a sign that your roof needs to be replaced. During a heavy storm, loose shingles might fly off the roof, causing damage to nearby houses and even harm to bystanders.

Damaged Roof Valleys:

Your roof’s valleys allow water to be drained from it. If they stop working, your roof will deteriorate, and water damage will spread throughout your house.

Round-Up: How to Know if There’s A Roof Replacement on Your New Home!

To replace your roof, you’ll need the skills and expertise of a roofing company. The process of installing a new roof is both time-consuming and challenging. No matter how much you like making things, this is not the type of project you should do.

The primary function of a roof is to shield your house from the elements. For example, if it isn’t properly placed or is constructed with defective materials, it may cause long-term damage to the inside and outside of your house.


What do you check for on the roof when buying a house?

The roof condition is the most significant consideration when purchasing a home. It must be mold-free and require no upkeep. Make that there are no cracks or holes.

If you see that some shingles are missing and patches are visible, the roof is relatively old.

Should people purchase a property with a damaged roof?

Roof replacement is a standard procedure, but maintenance work can be pricey.

If the roof needs replacement, but the home is generally in decent shape, and you receive a substantial enough reduction on the price, there’s no need to pass up the house if you like everything else about it.

But you could have trouble receiving purchase financing until AFTER the roof is fixed.

Sooner or later, every roof needs replacing, even slate! ( But slate can survive millennia!) Be cautious but don’t be terrified.
