Ultimate Guide to Estimating Your Roof's Age Without Climbing a Ladder

Introduction

There are many reasons why you might need to estimate the age of a roof. Perhaps you are buying a new home, contemplating replacing your own roof, or you are simply trying to plan and budget for when you might need to replace your roof in the future. You may or may not have the ability, tools, or knowhow to climb on top of the building to examine the state of the roof, but after reading this guide, you will understand the importance of knowing your roof’s age as well as how to safely and accurately estimate the age of your roof.

Understanding the Importance of Knowing Your Roof's Age

Your roof is one of your home’s first lines of defense against the elements. It keeps water, falling debris, and other hazards from simply dropping into your home and doing even more damage to your home and its inhabitants. That being said, it is important to be able to recognize when this defense needs to be bolstered. Water alone is enough to turn a simple roof repair job into much more costly and labor-intensive problems resulting from water damage. Being educated about what to look for when inspecting your roof can save you thousands and prevent damage to the rest of your home.

The Challenges of Estimating Roof Age from the Ground

When you assess the condition or age of your roof from the ground, you are at a disadvantage. For starters, you are fairly far away from the roof surface itself, and you may not be able to see details that you would be more likely to notice if you were up close and personal. Also, depending on the type of roof that you have, it may be impossible to see certain spots of the roof at all. Whether you are physically unable to climb a ladder, don’t have one, or simply do not want to assume the risk of climbing onto your roof, this guide will not only give you methods of checking out your roof from the safety of the ground, but it will also arm you with the knowledge of what specific signs to look for and what they mean.

Visual Inspection Tips

Spotting Signs of Wear and Tear

There are several things to keep an eye out for that indicate damage to your roof that you do not need to climb on top of your house to notice. For example, you may notice that there is moss or other greenery growing on your roof. Unless you live in a hobbit hole or other fantasy-inspired abode, this usually means there is an issue that needs to be addressed. If you have a shingled roof, inspecting your gutters and downspouts for grit from the shingles is a good way of telling if it might be time to replace. Another great way of determining the condition of your roof is to check your attic and ceilings for water stains or other evidence of moisture penetration, like rotting boards.

Identifying Roof Material and Its Typical Lifespan

When determining the age of your roof, it is important to remember that different types of roofing material age differently. Consider how we classify a dog’s age into “dog years.” The same principle can be applied to roofing materials with their different lifespans. A typical shingle roof can last 20-30 years, metal roofs between 40-80 years, and clay tile or concrete roofs can last over 100 years when properly cared for. Using GoNano’s nanoparticle technology can extend the lifetime of many different surfaces by permanently changing the molecular structure of the material. Depending on the material, you could see a life extension of 10-15 years.

Observing the Condition of Roofing Shingles or Tiles

Shingle roofs are very common because of their relatively affordable and simple installation. Tiled roofs have been around for hundreds of years. These roofs are made up of several smaller components similar to the scales of a fish. They should look uniform and even without broken sections or warped pieces. If you notice some tiles or shingles are missing or broken, it is probably time to consult a roofing professional to find out why it is happening and what can be done to repair it and prevent further damage.

Historical Research Methods

Reviewing Home Inspection or Real Estate Documents

Whenever you purchased your home, you should have been given access to various documents about its history. If you are lucky, the previous owner also kept records of repairs and replacements, including details of the installation and when it took place. Often, when you purchase a new home, contractors evaluate its features and foundational health. These documents can be very valuable for estimating the age of the roof.

Consulting with Previous Homeowners or Neighbors

If you personally know, or at least can contact your home's previous owner, you can ask them if they have ever had any work done on the roof, as well as details about the nature of that work and when it took place. Be sure to ask them if they treated the roof with any sort of after-installation products. For example, GoNano makes products that can extend the life of your roof beyond the typical lifespan. If you cannot get this information from the homeowner, asking around the neighborhood is another good way to get some first-hand info on your roof. Ask your neighbors who have been in the neighborhood the longest. That person will most likely be able to give you the best idea of the changes that your home has undergone over time.

Checking Local Building Permit Records

If you don’t want to or are unable to ask the previous owner or your new neighbors about the history of your home’s roof, you can always check local building permit records. These records are accessible to the general public and many cities have an online database for them. A quick internet search could lead you to great information about the history of your home.

Professional Opinion Without On-Site Inspection

Utilizing Drone Technology for Roof Inspection

For the tech-savvy, a drone could be used to safely and quickly get a detailed view of your roof. Drones are a great tool to either get a live view of your roof or record a detailed video of it to review later. If you do this method yourself, be sure to look at the roof surface, gutters, chimneys, and other structures that may be on your roof.

Seeking Virtual Consultations from Roofing Experts

Another great way to use technology to safely and quickly get information on the age of your roof is to use a virtual consultation from a roofing professional. The professional can look at aerial images of your home that are available through satellite images or aerial photography. This way, you can get the information you need without needing to be present for the inspection, and it can save both you and the professional time and money.

Using Online Roof Age Estimation Tools

There are online services that use artificial intelligence to compare highly detailed satellite images of how your roof looked over months or years. This is a fast and reliable way to estimate the age of your roof and the rate of change over a certain period. This information can lead you to make better decisions about when it is time to repair or replace your roof.

Indirect Signs of Aging Roofs

Increased Energy Bills as a Symptom of Inefficient Roofing

Besides the above-mentioned methods of checking out the condition of your roof to estimate its age, there are other less obvious signs to look out for that could indicate that it is time to consult a professional. You may be seeing an increase in your heating bills in the winter and your cooling bills in the summer. If one or the other increased, it would be easy to assume that your heating or cooling system was failing. However, if both are growing, it may be time to look into your house's insulation, specifically your roof.

Frequency of Roof Repairs and Maintenance History

Have you been needing a handyman to come out to repair leaks around your chimney? Has there been an unusual amount of buildup in your gutters or downspouts? If so, you could continue treating these symptoms of a bad roof without knowing that that is the underlying disease that your home could be facing. These “little fixes” often start becoming more frequent when your roof is nearing the end of its lifespan.

Assessing the Age of Similar Homes in Your Area

Often, homes in a neighborhood are built around the same time with similar designs, features, and materials used in their construction. Talking to your neighbors or gathering information about their homes from public records could lead you to better understand the age and life expectancy of your roof. Variables like storm damage, tree cover, and wind exposure are all things that could lead to different rates of aging, so be sure to take that information with a grain of salt. No two roofs are exactly the same, but this information is good to consider when trying to make an accurate estimate.

Preventive Measures and Next Steps

Regular Roof Maintenance Tips

After you have successfully estimated the age of your roof, the next step is to consider what you can do to keep your roof from aging faster than it should. There are a few simple tips that can vastly improve the lifespan of your roof. Keeping debris off of your roof is important because any obstruction of the path to your gutters leads to water pooling and eventually penetrating the other layer of your roof. Keeping your gutters cleaned out prevents water from soaking the underside of your shingles and leading to water damage to your home. A great way to get ahead of these issues is to preemptively trim any tree limbs or other foliage hanging over the roof. Another great way to extend the life of your shingles, concrete, roof, wooden surfaces, or roof membrane is to use GoNano’s line of products designed to extend the life of your roof by 10-15 years.

When to Consider a Professional Roof Inspection

If you are noticing water damage in your home, missing or damaged sections of roofing materials, or an increase in heating and cooling bills, it is in your favor to contact a roofing expert sooner rather than later. Staying vigilant and paying attention to changes in your roof's appearance or function can save you more in the long run by treating the cause of the problem before it leads to damage to the rest of your home.

Planning for Roof Replacement: Timing and Budgeting

If you have an accurate estimate of the age of your roof, you can have a much better idea of when you will need to replace it. Arming yourself with this information can make it much easier to plan and budget for the repairs or replacement when they are necessary. Being surprised by the need to replace your roof or make repairs makes the situation worse. When you expect to invest in the longevity of your home, it doesn’t sting as much as a sudden need that cannot wait to be fixed. There are also alternatives to full roof replacements, such as GoNano’s asphalt shingle rejuvenation treatment, that can extend the lifespan of your shingles by utilizing nanotechnology sealants!
