Testing Method
We started by covering the asphalt shingles on our test house with a coat of urethane sealant, then waited five days for the coating to cure.
We applied a second coat of sealant, waited five more days, then removed the shingles from the house and placed them on a flat worktable. We covered them with plastic sheeting and used an air compressor to clear each shingle of any debris.
After cleaning each shingle, we used a common utility knife to slice through the asphalt shingle, starting at the edge and cutting through to the center. Once we’d punctured each shingle through the center, we used a box cutter to slice the shingle into two even halves.
We repeated this process until we had cut through all of the shingles. We then took photos of any slices that had been caused by our cutting procedure and noted any additional damage in our results notes.
After cutting all of the shingles, we used an air compressor to blow off any remaining dust and debris and then took photos of the damage to each shingle’s exposed edges. When testing for this feature, we applied sealants to both sides of the shingles, one side at a time.
We took photos of each edge after the sealant had dried for a few hours. We also used a sharp utility knife to slice through each shingle after allowing it to cure for 24 hours, measuring the widths of any slices that occurred during this procedure.
From these results, we were able to calculate a durability ratio for each coating: The ratio was calculated by dividing the width of each slice by that coating’s overall durability score (the durability score was calculated using all of our tests combined). A higher ratio number indicates less durability and greater susceptibility to damage caused by weather or human contact.

Things to Keep in Mind Before Buying
Water Resistance
The main purpose of sealant is to protect asphalt shingles from water damage, so it is important to look for a sealant that is highly water-resistant. Look for sealants that are specifically designed for asphalt shingles and that have the ability to resist water, moisture, and other weather conditions. Additionally, many sealants come with a waterproofing guarantee, so make sure to read the label to ensure that the sealant you are purchasing is able to protect your shingles from water damage.
UV Protection
In addition to water resistance, you should also look for a sealant that offers protection from harmful UV rays. The sun’s UV rays can accelerate the aging process of asphalt shingles, so a good sealant will provide protection from these rays and reduce the wear and tear on your shingles. Look for sealants that are specifically designed for asphalt shingles and that have a strong UV protection rating.
Durability
When selecting sealant for your asphalt shingles, look for a product that is designed to last. You want a sealant that is designed to withstand the elements and that won’t crack or peel over time. Many sealants come with a warranty, so make sure to read the label to ensure that the sealant is designed to last a long time.
VOC Content
Volatile organic compounds (VOCs) are chemicals that can have a negative impact on the environment and human health. When purchasing sealant for your asphalt shingles, make sure to check the label for the VOC content and select a sealant that is low in VOCs. Look for sealants that are specifically designed for asphalt shingles and that are low in VOCs.
Application Method
Lastly, you should consider the application method of the sealant you are purchasing. Some sealants are designed to be applied with a brush or roller, while others are designed to be sprayed or poured on. Make sure to read the label to ensure that you select a sealant that is designed for the application method that you prefer.
What Is the Best Coating for Asphalt Shingles?
Asphalt shingles are a popular and cost-effective roofing material for homes. To keep them looking their best and prevent them from deteriorating, a coating is recommended. Polyurethane is the best material for coating asphalt shingles as it offers superior protection from wear caused by foot traffic and impact from hail.
It is extremely durable, long-lasting, and resistant to moisture, heat, and UV rays. It is also a great choice for preventing water damage and discoloration. Polyurethane roof coatings can be applied with a brush, roller, or sprayer and come in a variety of colors and finishes.
They will also increase the overall lifespan of your roof and add to its aesthetic appeal. It is important to have your roof inspected regularly to ensure it is in good condition and to ensure the polyurethane coating is applied correctly. With proper maintenance and the right coating, your asphalt shingles will look great and last for years to come.
Can You Put Roof Sealant Over Shingles?
It is not recommended to apply roof sealant over shingles. Doing so can cause severe damage to the shingles and ultimately, the roof. The sealant may also block any ventilation and stop essential airflow which can result in dampness and condensation build up in the attic.
Instead, it is important to consult the shingle manufacturer for any specific actions that need to be taken. ARMA (Asphalt Roofing Manufacturers Association) strongly advises against the application of any type of field-applied coating over installed asphalt shingles. It is very important to read the instructions and product labels carefully before applying any coating to the roof.
Different types and formulations of roof coatings will have different instructions and requirements. It is important to remember that any type of coating should never be used to cover up existing roofing problems. It is not a substitute for repairs and maintenance.
Can You Seal Asphalt Shingles?
Sealing asphalt shingles is recommended in some cases, although it is not necessary for all asphalt roofing. By applying sealant to the shingles, it helps to protect them from the elements and can prolong the life of the roof. Sealing is especially recommended for shingles installed on slopes greater than 12:12 or when installed in very cold weather.
The Asphalt Shingle Manufacturers Association (ARMA) recommends hand-sealing of shingles in these cases, as it is more effective than machine-sealing. It is important to use the correct type of sealant for the shingles, as different types of shingles may require different sealants. Applying the sealant improperly can also cause damage to the shingles.
It is therefore best to consult a professional roofer before attempting to seal asphalt shingles.
What Can I Put on My Shingle Roof to Stop Leaks?
The best way to stop leaks on a shingle roof is to ensure proper maintenance and repair. Regularly inspecting the roof for any damage and making necessary repairs can help prevent major issues. It is also important to ensure that the shingles are properly sealed and the roof deck is adequately ventilated to prevent moisture buildup.
Adding a layer of waterproof material such as an underlayment or roof coating can also help keep water out of the home. Finally, cleaning the shingles periodically can help prevent the buildup of debris, which can cause leaks. With the proper maintenance, a shingle roof can remain leak-free for many years.
Can You Use Leak Stopper on Shingles?
Leak stopper is a great solution to combat roof leakage. It is designed to be applied to a variety of roof surfaces, including shingles, built-up roofs, SBS modified roofs, metal roofs and many other surfaces. It is an excellent choice for roofs that are prone to leaking due to their age or other factors.

With leak stopper, you can rest assured that your roof is waterproofed and protected for years to come. It is truly the best choice for shingles and any other roofing system.
Can Flex Seal Be Used on Shingles?
Flex Seal can be used on shingles, but it is important to be careful. It should not be applied in large quantities as excess solvents can cause the shingle coating to become soft and form blisters. The best option is to use a good quality brand of asphalt plastic cement, as this can be applied from a can or caulking tube.
This type of adhesive is also much more durable and less likely to damage the shingles. When using any type of adhesive on shingles, it is important to follow the manufacturer’s instructions and take great care to ensure that the shingles are not damaged. This will help to protect the roof from future damages.
Furthermore, it is always recommended to have a professional inspect the roof regularly to ensure that it is in good condition.
What Is the Best Way to Seal a Shingle Roof?
The best way to seal a shingle roof is to use a high-quality sealant designed specifically for the application. Be sure to choose a sealant that is designed for the type of shingles you have. Before applying the sealant, thoroughly clean the roof and make sure it is free of debris.
Make sure to apply the sealant in an even layer and in the same direction as the shingles to ensure proper adhesion. It is important to apply the sealant on a dry day and to allow the sealant to cure according to the manufacturer’s instructions. Once complete, inspect the sealant to make sure it is covering the entire shingle roof and repair any gaps if necessary.
With the right sealant and proper application, your shingle roof will be properly sealed for a long time.
What Can I Put on My Shingle Roof to Stop Leaks?
When it comes to shingle roofs, there are many ways to stop leaks. Unfortunately, the Asphalt Roofing Manufacturers Association (ARMA) strongly advises against the use of any type of field-applied coating on installed asphalt shingles. The best way to protect against leaks is to properly install the shingles, as well as maintain them regularly.
If you want to protect your roof from water damage, you should inspect it at least twice a year. Look for damaged shingles, debris, and other potential sources of water infiltration. If necessary, you can also use flashing to seal off areas where water can enter.
If you do decide to use a roof coating, be sure to consult the shingle manufacturer first to learn about the best type and formulation for your roof. Taking these steps will help you protect your shingle roof and stop leaks.
Can You Put Roof Sealant Over Shingles?
Sealing a flat roof is essential to prevent damage and to keep your roof in good condition. But what about shingled roofs? Can you put roof sealant over shingles? Generally, no. While roof sealant can be used to help prevent leaks in certain areas, it’s not recommended for use on top of shingles.
The reason for this is because the sealant can damage the shingles, decreasing the lifespan of the roofing system. Additionally, roof sealant is not designed to be used in areas of direct sunlight, so it’s not recommended for use on top of the roof. If you have a leak in your roof, it’s best to contact a professional roofer who can inspect and fix the problem.
Roof sealant should not be used as a permanent solution for a leaking roof. If you’re looking to extend the lifespan of your shingled roof, consider applying a roof coating.
Should I Seal My Roof Shingles?
Applying roofing tar is a great way to prevent and repair leaking around flashing. It is especially effective in areas that can’t be reached with a spray-on sealant. This tar can be applied manually with a brush or spreader, and it is designed to fill any cracks, crevices, or separations around flashing.
But should you seal your roof shingles? It depends on the condition of your roof. If the shingles are in good condition and not leaking, you may not need to seal them. However, if there is significant wear and tear or the shingles are leaking around flashing, sealing them with roofing tar is recommended.
Depending on the severity of the leak, you may need to replace the shingles or perform further repairs as well. Sealing your roof shingles can be a great way to keep your roof in good condition and save money on costly repairs in the future.
Frequently Asked Questions
Can You Put Tar Over Shingles to Stop a Leak?
Yes, it is possible to put tar over shingles in order to stop a leak. However, it is not the recommended solution. Applying tar over shingles is a short-term solution that can be used in an emergency situation, but should not be used as a permanent fix.
Over time, tar can crack, allowing water to penetrate and cause further damage. Additionally, tar does not provide adequate ventilation, which can lead to trapped moisture and rotting.
