Identifying and fixing roof leaks can be a time-consuming task, but it can also be less time-consuming than locating the source of water. Water often enters homes near things that go through the roof, such as vents, dormers, and flashings. A common fix for roof leaks is applying roofing cement or silicone caulk, which can be used to repair small leaks on shingle roofs or flashing around a damaged area.
To prevent mold growth, rot, and lasting water damage, it is essential to find and repair leaks. Certain roof types, such as slate, tile, and galvalume (metal), should be repaired by a roofing contractor with experience with that particular material. Henry® Wet Patch® Roof Leak Repair Sealants can help with this process.

How to stop roof leaks from inside?
To fix a leak, create a temporary patch using plywood or shingle and roofing tar. Spread the tar into the hole on the inside of the roof and then place the plywood or shingle on top. Map the leak’s location using a measuring tape before leaving the attic. Once rain stops, use rubber-soled shoes to locate the leak on the outside of the roof. Use more roofing tar to complete the temporary patch. Contact your local roofer for a permanent patch, and consider roofing replacement if dealing with multiple leaks or if your roof is getting old.
Roofing replacement should be completed every 15-25 years for asphalt shingles and 40-60 years for metal roofing. If the leak cannot be found, cover it with plastic roof covering, even if you don’t have access to the attic.
What is the best solution for roof leakage?
Patching and sealing are simple and cost-effective solutions for minor roof leaks. Identify the leak area and use roofing cement or sealant to seal any cracks, gaps, or damaged spots. Clean and dry the surface before applying the patching material. If the flashing is damaged or deteriorated, it may need repair or replacement, which may require specialized tools and knowledge. Consult a professional if uncertain.
Clearing clogged gutters and pipes regularly can prevent water backup and seep into the roof. Regularly clean debris from gutters and ensure clear downspouts to direct water away from the foundation. These simple maintenance tasks can prevent roof leaks and water damage.
Is it normal for a roof to leak in heavy rain?
Plumbing, chimney, skylights, metal roofing, and condensation are all potential sources of leaks during heavy rains. A house with a vent pipe and flashing can make it more vulnerable to leaks, while a chimney is more prone to roof leaks due to rain falling into the chimney, angle flashing, or masonry surface. Skylights are another common leak source due to damaged or improperly installed flashing, gaps around framing, or condensation dripping off uninsulated skylights.
Degraded shingles eventually wear out, leading to leaks during heavy rains. Metal corrosion and loosening seams in metal roofs can also lead to leaks. Insufficiently ventilated attics can allow moist air to collect and condensation to collect on vent pipes, causing water to drip into the attic and onto the ceiling. Heavy rainfall during warmer winter days can worsen the situation. Southeastern Metals™ offers various products to prevent water damage from flashing, skylights, metal roofing, and other issues.
What stops a roof from leaking?
To seal leaks in roofs with removable tiles, use roofing tar to seal gaps. Place plywood or shingles across the gap and apply roof tar to ensure complete sealing. For hard-to-find leaks, use polyethene plastic (PE) to reduce the affected area and catch rainwater. Secure four feet of plastic sheeting over the area, secured with nails or staples, to minimize future leaks. These methods can help prevent leaks and ensure a leak-free roof.
How do I stop my roof leaking in heavy rain?
To prevent roof leaks in heavy rain, follow these seven tips: locate the leak source, clear the area, use roofing tar to seal gaps, use polyethene plastic for hard-to-find leaks, replace old or broken shingles, use tarpaulin for quick fixes, and seal joins and joints. These tips can help prevent costly repairs and prevent damage to interior walls and ceilings. If you’re not a roofing expert, these tips can help you identify and address leaks before they cause significant damage.
What is the best thing to seal a leaking roof?
The choice of the best roof leak sealant depends on factors like seal size and roof type. Individual sealant packs typically cost between $20 to $50, while larger quantities for whole-roof sealing can cost $150 to $200. After researching over 20 top roof sealants and reading hundreds of customer reviews, Dicor Self-Leveling Lap Sealant is recommended for small roof leaks, while Liquid Rubber’s Waterproof Sealant is recommended for larger leaks.
Other top picks include Gorilla Waterproof Patch and Seal Tape, Flex Seal Spray Rubber Sealant Coating, Liquid Rubber Silicone Roof Coating, and Sikaflex Self-Leveling Sealant. These sealants are suitable for homeowners who need to quickly fill small gaps on roofs or other areas of their home.
Who is the best person to fix a leaking roof?
Hiring an experienced roofer for roof leak repair is crucial for ensuring a professional and timely solution, saving time and money in the long run. A warranty is essential for a secure roof, providing peace of mind in case of a leak. It ensures that the roofing professional will return to address the issue, providing a sense of security and a superhero ready to save the day. Therefore, it is essential to consider the benefits of a warranty when repairing a roof leak.
How to fix water leaking from roof?
The most common method to seal a roof leak is to apply roofing cement or silicone caulk, which can be done using a caulk gun. Before repairing a leak, consider the following factors:
Wait for warm, dry weather. Tearing down leaking roof sections on a rainy day could lead to worse damage and require further repairs.
Check for any damage to the roof sheathing or substrate. If the leak is severe, it’s best to wait for warmer weather before attempting any repairs.
What is the best way to repair a leaking flat roof?
Lap sealant can be employed as an expedient measure for minor rubber roof leaks. However, a more enduring solution is a patch repair utilising self-adhesive flashing and self-adhesive rubber tape to obfuscate the opening.
Are roof leaks hard to fix?
Roof leaks can be challenging to identify and fix, potentially posing a threat to your property’s livability. It’s crucial to identify the leak area and address it promptly to prevent further damage. If the repair is significant or you cannot handle it yourself, consult an insurance agent and an experienced roofing contractor for coverage. Minor leaks can be fixed by yourself, and there are various ways to address them before the situation worsens. Understanding the signs and solutions to roof leaks is essential for maintaining your property’s safety.
📹 Roof repairs with Flex Seal: Please don’t do it.
Helping Roofers Become Successful Business Owners. Want have a better understanding and learn how to operate a business?
Lol Flexseal works great for these exact uses not everyone wants to call a contractor for a tiny leak for insurance for a single small issue and this stuff works amazing especially if you get the color that matches your roof or clear it works amazing for small leaks which is exactly what it is designed to do. This guy doesn’t want you to use it because he wants you to call him.
If I was missing a shingle, I would use the replacement method recommended by Dimitri. But I have an imperceptible leak on an almost-flat roof with skylights. I used Flex Seal around where I suspected the leak to be and it held up for four years. The leak was caused by a crappy job the contractor did; I had more leaks AFTER he finished. His attempts at repairs were both hilarious and infuriating. If I could find a good, honest contractor, I would hire him – as I’m 71 years old and not quite as nimble as I used to be. But for now Flex Seal is my go-to for a small leak.
If contractors want people to call them, they should lower their prices. I paid $500 for a guy to come out and put tar on my roof. The first rain it leaked. I had to get ugly to get a full refund. I went through Angie. They wanted to give me a $50 credit. I did get a refund after I went all the way off. I can put my own tar on for cost of supplies thank you. I don’t trust any of them.
OMG due cut it out. It is so obvious what you are doing here. You want us to call you, so we spend 8 grand on a new roof lol. There is absolutely nothing wrong with using Flex seal for small leaks and repairs. Of course, you’re not going to Flex seal your whole dam roof lol. I love his first reason: Its ugly” lol Wow dude that’s one of your reasons. Dude 99 percent of people could care less about a small black spot on the top of the roof where nobody is going to see. So yeah let’s call in a roofer to patch a small leak for about 1,000 bucks or go by a 18 dollar can of flex seal. Its a no brainer.
Sorry Dimitry but it’s obvious that you are a roofer and wanting to get more clients, but the problem is you charged too damn much… If I need major work, I’ll call you, but for minor patches, I’m sticking with Flex seal. Yesterday, I got up on the roof and pull up the tiles and found where the branch had cracked the deck… Anyway, some of that metal wire tape couple with flex seal is doing great (plus I put some of that new synthetic felt on it in that area over the Flex seal)… Well, Dimitri you can keep your overpriced labor.
If you have a leak — screw the roofer who won’t be there for 45 days . screw your insurance claim that would pay for damages you could have prevented. Emergency repairs are an EMERGENCY. I say .. keep some on hand because it will happen at night or on a Holiday weekend. If some roofer is to lazy to to scrape off a little goo — then he shouldn’t be on a roof. If you’re ambitious enough to make the patch, you’re probably going to make later repairs yourself anyway. I don’t know which is more irritating, listening to complaints in English or listening to roofers who can’t speak English ( usually Spanish ).
The flex seal paste is legit as a temporary solution. Super thick and seals under water. Had some internal copper gutters on a 125-year-old house. The slate had cut a hole in it and it was draining into the house needed it plunged while raining. Flex paste worked for a good 5 days of heavy rain until we could get it fixed.
I say try it first if it does not work then use tear from Home Depot at the roofing supply section that has the shingles to use it and try to do it your self the article says to call a roofer but some people can’t afford to pay that when you can do it yourself and it’s better to do it your self because do you want to spend 20 bucks on a gallon or a small buck of tear or 2000 or roughly that just to fix a leak I’m not sure of the price but people tend to try to save money that the job could be small and quick to do.
Yeeeeah great contractor spiel on you tube again …..flex seal is only supposed to be a short term fix Nobody and even the company ever said otherwise In fact I have had to use it on my dormers of my house after a new roof was installed …..because you guessed it ….. the CONTRACTOR messed up ….lol go figure…..two years later having a hard time getting that contractor to come back But hey it worked and is still working after six months Still chasing that contractor by the way and his warranted work 🤣
The guy is using flex seal to patch the roof I am sure he does intend to keep it like that permanently! So my question is who r you trying to sell your bullshit to??? U said #1 don’t do it because it’s ugly!? If it stops the rain water getting through the roof and causing more damage I don’t care how ugly it is! #2 U also just said roofing material shingles isn’t water proof it sheds the water off the roof and if the flex seal was flat it would leak because it’s not water proof!! What neither r the shingles bro!! I have no idea what ur goal is hear? Because I sale and install shingles for home owners and if they had to use flex seal until they got the roof replaced or repaired id tell them good job good 👍 thinking! Hell id recommend it to not cause more damage!! O and what is your other options use a tarp!?? If you don’t install it right water goes right through so what options do they have to repair short term!!? And and again what is your point!!!!!
I watched entire article … and still do not understand what the main point of the article actually is. Because he certainly did not clearly explain why Flex Seal should not be used for roof repairs. The title of the article suggests there would be clear-cut evidence at to why Flex Seal should not be used for roof repairs. Seems he talked on and on about using, or rather, not using Flex Seal … but I just did not see any examples of any actual failures from Flex Seal usage. Thus here I am left wondering why he created this article. Did he do it solely to maximize ‘hits’ on his article …or what? ……Furthermore, he also talked a couple minutes about not using Flex Seal on any type of house siding, but what does house siding have to do with any so-called roofing repair article? …………. ……….. Look, I had some wind damage that ripped a couple flaps off my 3-tab shingles on my unheaterd detached garage … and all I need is a temporary ‘fix’ to get me through just this one mid-Michigan winter. Then in spring, I will rip off the entire roof and replace it all.
I used roof cement which is thicker looks like tar after Hurricane Beryl took out the satellite antenna from the roof . What I did I put the screws back in the holes and applied roof cement over and around it, of course after the hurricane left our area . We had more rain the following days and it wasn’t leaking anymore. Of course that is just a temporary fix . Thanks!
I agree! Those products is like a miracle and it does works great. You would save lots of money. At the same time, I understand why the maker of this article completely disagree with the idea. Because he’s going to lose his job or it’s not going to do any good for his constructing business. Not all people likes to spend lots of money to hire someone who can fix a leaking problem in their homes. As much as possible people love to Save money and just do a DIY themselves.
I got a “new roof” 2.5 years ago. They were supposed to put all new decking on, then shingle. I got home from work and they had shingled over rotten wood and refused to tear it up and do what i paid for. Now i have a bad leak where my garage meets the house. Im in Wisconsin and we just got 18″ of snow, it melted, now its leaking. Due to everything being more expensive now days im left with trying to find something that will stop the leaks. Im thinking of dumping a shit ton of tar on that area just to stop my current headaches. Flexseal didn’t work! What’s a good product to “fix” this situation? I know i need a real roofer to figure it out, but thats not in the budget right now. Suggestions?
Hello, I have a leak between my kitchen and attached sun room which was built after the house was built. The sunroom is attached to our 2 story home. We replaced the room less than 5 months ago to fix the leak. But it’s leaking again. The contractor is no longer responsive. I was going to try to buy some type of caulk or sealant to apply. But after your article, that sounds like a bad idea. Do you have any advise? Thank you in advance.
You are correct Dmitry, Here’s the what’s missed on this demonstration and Belcher has no clue. First of all the demonstration is set up for a steep pitch( I want to know how the homeowner is going to get up that roof) then he tears off a field tab in the middle of the shingle instead of over the lower butt lap edge. Try covering that joint without loosening the tabs above it and then that joint will pull the crap apart. In the demo he pounds 2 nails through the shingle when in fact there is one nail only and the wind isn’t going to pull that out. Then he is assuming that all homeowners can get up there to do it. If you have to send someone up there to do a spray job then it better be a qualified roofer . That repair takes 5 minutes to replace the tab and caulk the loosened tabs around it. Why wait for the coatings to dry? I love it when Flex guy’s try to quantify a garbage product to do roof repairs.
Ok, first of all, if it’s not leaking it’s repaired. Ugly or not. Any roofer that begins to talk about warranties either doesn’t know what they are talking about or knows you don’t know enough about it. The only warranty anyone should be worried about voiding really is the craftsmanship warranty. Anyone looking to do a repair like this is someone strapped for cash or someone who doesn’t care what it looks like because it’s likely a very old roof with no real warranty of any value.
So it works. THe question is, for how long? Does layering 3-5 layers get you maybe an extra year, or does it last longer than the rest of the roof? Somewhere in between maybe? How foolproof is this really? Seems simple to me… but what am I not understanding? You made a good point about back flush. I guess if you can replace the shingle, thats generally better.
Your thoughts on the following? The 3 year article update from “Online Auto Repair articles” said it held up, but it’s imperative to use mesh in conjunction with the flexseal for it to be effective, long-term. In the comment section, he agreed with a comment that in retrospect he would’ve used steel mesh for the project for maximum durability. He repaired the roof in 2016 did the updated article in 2019 and in the comment section as recently as two months ago replied to a comment making no indication that it has failed yet so that’s a total of seven years. Otherwise, not using mesh, (steel) flex seal alone will be prone to cracking overtime.
On the can it says not for professional roof repairs. All he has to do is show that part which tells you that on the can. This is just a demonstration on how great it seals. He talks about how it doesn’t work on flat roofs, but you don’t use shingles on flat roofs, you use roll roofing. I use it on my camper and it works great and it has a flat roof. It’s rubber, water will not penetrate it and it only takes two coats the most not 5 coats. Don’t listen to this guy. Sounds like he’s trying to get more business for his roofing business
Number 1: who cares if it is ugly, Number 2: no warranty, Number 3: there are enough gaps in the roof, Number 4: a few seals won’t affect flexing, Number 5: the roof is angled there won’t be a dam. Flex Seal with spray followed by flex tape is a great fix. If there are a lot of missing pieces then of course you would need a roofer. But today there are many scam roofers. Fix it yourself, Gorilla also has flex tape for half the price, until the whole roof needs to be replaced may be the best option.
Holes through the shingle can be mended with silicone caulk which will last as long as the shingle guarantee is for. I’ve mended shingle that way and it lasted 25 years. That’s longer than the shingles are guaranteed for. I don’t believe that many understand how roofing systems work and are appalled by the thought of mending torn shingles or flapping shingles or individual holes that way. But it works. Flex seal is a variation on the theme but is more brittle and will not give as much as silicone caulk. I use GE 100% silicone caulk as it has a 25 year guarantee.
Your insurance policy has a 2% deductible. Often the damage doesn’t meet the deductible. And if you do make a claim, the insurance company will not renew your policy. If you hire a contractor, and they know you likely have a 2% deductible and they’re savvy enough to look up the value of your home, they will give you an estimate just below the deductible regardless how little damage there may be. And if you’re a woman, be prepared for your contractor to try to scare you sh**less so he can sell you additional services. Ask me how i know 🤨
Since he is asking for comments, I’ll say this is stereotypical for a tradesman. I understand his approach is the ‘perfect’ one, but most people aren’t willing to pay >$1k for a professional to come out to repair a pinhole leak in a roof. Flex Seal it or tar it first. If it works, it works. And it probably will. If it doesn’t, pay the exhorbitant expense.
that is a temporary repair not a permanent one; go figure you speak but say very little that makes sense ( I know you’ll call me a hater) but seriously stop with the BS, it’s just a temp repair, ever tried calling insurance company or contractor (They may show up or not) get real and provide clear honest information, for once in your life, OMG
If the contractor bothers to show up where I live unless you are spending for a new roof they arent coming. In fact the roof is year old and the clown that did it screwed it up for now it save my butt. Maybe their should be regulations on contractors. I had to use it around a vent because contractor didnt do it properly i silicone it used some flex seal it stopped the leak. Im sick of getting screwed over by contractors.
Our world of work is very different as I only design and build natural and traditional architecture so…ZERO…concrete, steel, plastics, and modern and industrial polluting materials. That stated, I loved how you described a roof and explained why this product is complete and utter…CRAP!!!…if anyone is trying to actually do a “real repair” of a roof…Good job!!!
I had an expensive flat roof installed by a so called professional roofer. The edge of the flat roof leaked where it joined to a neighbpurs flat roof. Called them back and they squeezed some sort of gunk into the join. Leaked again a few weeks later. In the end I repaired it my self with a combination of sealent/adhesive and flashing strip. Don’t talk to me about roofing contractors, crap!
I agree with that statement of any roof repair must be done by a professional roof installer or an experienced contractor… I believe that the main purpose of the product (flex seal) is for a temporary fix in the case of the roof shingle missing nobody can get any contractor to take care of the problem right away so flex seal or any other similar product isn’t made for a long term fix probable that piece of information should be expressed on the article.
So i wont be using this flex seal unless it comes in clear lol. Ive got a conservatory it came with our house. It leaks like a cunt ive had roofers and upvc guys out to fix it theyve done endless repairs now its my turn though im using polar solutions clear coat. I will reseal between each roofing panel and the panels to ensure there are no gaps, it doesn’t need to breath if it traps heat great especially in winter as its cold as shit in winter. Then where the rain majority gets access is the gutter end where it meets the house. We have paid for new guttering the lead flashing is covering the gap but water will find a way if it can so im removing the lot n expanding foaming the gap, then using leakstop by polar solutions, then refit the lead flashing n reinstall the gutter n that should be that. Ive tried the pros they have no clue so its my turn. N as using clear it wont look ugly.
And how about not using Flex Seal to seal how about using it to put a coating on each individual shingle to extend the life of that shingle don’t seal up the seams in the edges. You know if you need a couple more years to save up money so you can actually afford a freaking $30,000 roof instead of taking a loan against your house and your interest rates now 7% you know throw some freaking Flex Seal on each shingle and you know 500 bucks gives you another 4 years. Don’t go broke being a purist
I think it is interesting that he says that even just simply placing a tarp for the problem later would suffice. I mean if it is for just a SHORT SHORT TIME, like long enough to schedule an appointment for the proper kind of repair job person, to get a consultation scheduled within I would say atleast 3 days of first initial need to repair.
Flex seal has the perfect draw for the humans brain. It appeals to laziness, the easy way out, no concern if it really works, no concern what is the right way to repair. It must work because the friendly entertaining chubby guy says its the best. I’ve used it on three projects and it failed shortly on each. I will not waste money on this again….but had to try it.
I see this stuff occasionally on roofs around pipe jacks and flashing. Flex seal does NOT appear to hold up well to UV rays. Call a roofer and see if he can identify if the leak was caused by a peril covered by your insurance. If it’s just one shingle and you’re adjuster deems that the roof is not repairable, you may get a whole new roof for just the price of your deductible.
I’ve seen numerous flex seal repairs on roofs, be warned. It’s a temporary fix. It will crack, and it will leak eventually. In most cases, on shingle roofs, you create a bigger problem, and when a roofer goes to fix it, he will charge you more. I will charge you more if it has been flex sealed, or there has been another similar sealant used..I understand if it’s temporary, but a lot of roofers tarp your roof for free. Tarpping would be a better bet for temporary fixes as dimitri pointed out.
