Your roofing stands up to the elements 24/7 and needs to be in tip-top shape to perform its primary function of protecting your home. Although there are a variety of components to a roof, all of which need to be installed with precision, the roof sealant gives a final touch when it comes to protecting your home.

When properly applied, this defensive coating—known as a sealant—both safeguards your roof from water intrusion, and adds a durable layer of security to it.

Roof sealant extends the roof’s life and lowers its possibility of being damaged from the weather. If your sealant is bad or isn’t applied properly, tiny openings and cracks may occur, eventually leading to roof leaks.

Spotting the early signs of faulty roof sealant can help you bypass costly repairs in the future.

7 Ways to Spot Improperly Applied Roof Sealant

Dayton’s weather can be humid, moist, and stormy. As a result, your roof’s surface can become weakened.

Low quality roof sealant can open the door to a compromised roofing system that needs repairs or replacement sooner than it should. And improperly installed roof sealant can lead to a roof replacement if the situation is left unaddressed.

Here are some signs your roof sealant was either bad or wasn’t applied right the first time.

1. Curled and Cupped Shingles

When there is no waterproof sealant applied on your roof, it’s easy to spot because shingles will look curled or cupped over time.

2. Distorted Looking Shingles

If your roof shingles look contorted, warped, bent, or buckled, sealant either wasn’t applied properly or at all.

3. Missing or Broken Shingles

If you have missing shingles, you’ll see different colored patches on your roof, or you may find them in your yard after severe storms.

4. Compromised Roof Valleys

A roof valley consists of any planes on your roof that are joined together. These areas are typically sloped, and when they aren’t sealed properly, moisture penetrates them. It happens because sealing wasn’t applied properly when your roof was installed. This problem is spotted by checking the seams of your roof. It’s safest to stay on the ground and allow a roofer to discover if this is the situation.

5. Roof Leaks

One of the most dreaded problems a poorly sealed roof can produce is roof leaks. When the moisture on your roof penetrates into it, and shingles become compromised, roof leaks result. They will show up in your attic or as brown spots on the ceilings of rooms in your home’s top floor. If you see signs of roof leaks, it’s vital you contact a trusted roofer to inspect the situation promptly and address it with roof repairs or replacement.

6. Cracked Flashing

Flashing is a thin piece of metal that goes under shingles on the joints of your roof to create a water-resistant barrier. Some flashing is exposed and some is concealed. If flashing breaks, large cracks will be noticeable. This may occur due to improper sealing application or corrosion of flashing over time.

7. Missing Flashing

Both your chimney and skylights should have flashing around them to protect your home from moisture intrusion. If your flashing goes missing (or is faulty), it’s usually because the seal around them broke. This problem is likely caused by improper sealant application.

Why Properly Applied Roof Sealant Matters for Your Home

The proper application of a good quality roof sealant will hinder water from penetrating and saturating your roof (not to mention your attic and the ceiling of your home interior)! Breathable roof sealants allow moisture to actually evaporate through them. Properly applied roof sealant will improve your energy usage and lower utility bills.

Sealants also prevent the unhealthy and unattractive growth of mold and algae on your roof. A sealant’s low permeability makeup keeps moisture from being retained.

Get the Protection You Deserve for Your Biggest Investment!

By all means, applying sealant is not a DIY project. You can avoid the dangers associated with climbing on your roof by hiring a roofer to apply or reapply sealant. They will inspect your roof, repair it where needed, and prepare it to be sealed. When weather permits, the full roof will be sealed with excellence and given ample time to dry. Experienced professionals apply sealant so you get superior results.

At American Way Exteriors, we perform state-or-the-art drone roof inspections so you enjoy the full value out of your roof for its lifetime. Our drone takes accurate images and precise measurements. This simple procedure is super convenient for you, and won’t disrupt your day (since no one needs to climb on your roof, and it’s super quick)! Contact us to schedule a roof inspection for your Dayton home.

They did a great job installing Hardie siding, and they also replaced all of our gutters and downspouts. Would highly recommend! Luke was an awesome sales rep, and the crew did an outstanding job!

American Way Exteriors completed a full siding and trim replacement project for us July 2025. They were easy to work with from the beginning to the end. Every person we interacted with at American Way Exteriors treated us like a valued customer, and we found Luke and Oscar to be exceptional. Luke was our first contact and sales rep. He walked us through all the options and associated costs and answered all our questions. Another exceptional experience was the on-site project manager Oscar. Oscar was at our house nearly every morning (always texted us when he was on his way or on-site) and every evening. The project was completed within the time frame we discussed. The on-site crew was professional, courteous, and respectful. We love the way our new siding looks and appreciate the great experience from American Way Exteriors.

We had James Hardie siding installed and ProVia windows installed. The experience with this company couldn’t have been better. We will definitely use them for all of our future exterior remodeling needs. I would recommend this company for anyone needing work done to their home.

We had Hardie siding installed this summer. Amazing experience from start to finish. They told us ahead of time the day it would be finished and it was actual done that day which is unheard of in construction. The fit and finish is what sold me and the fact they had a list of 20+ houses in the area to go see before we committed. Really happy with Luke who was our salesman. Oscar was in the field checking on the workers every day and answering all our questions. It was really kind of a unicorn experience on a remodel. Would absolutely do again!

We are moving from California back to Ohio and bought a house over a quick weekend. All was good but there was one potential siding issue. Amercian Way went out and inspected the siding and gave me a great report that said there was no structural issue, just cosmetic. Their honesty meant no business for them. But if and when I do need siding support, I will call American Way. Their communication and evaluation was quick, professional, and detailed at every step. Thank you.
