Flat roofs are an excellent choice for commercial and industrial buildings. However, they are susceptible to expansion and contraction due to temperature changes and structural movements, which can cause damage to the roofing system. Flat roof expansion joints are used to accommodate these movements and prevent damage to the roof. It is highly recommended to contact a professional roofing team to fix your joints. In this article, we will explore how flat roof expansion joints work.

What are Flat Roof Expansion Joints?

Flat roof expansion joints are designed to allow the roof to expand and contract as a result of temperature changes and structural movements. These joints are installed between two sections of the roof to absorb the movement and prevent damage to the roofing system. Expansion joints are made of flexible materials that can stretch or compress to accommodate the movement of the roof.

How do Flat Roof Expansion Joints Work?

Flat roof expansion joints work by providing a flexible connection between two sections of the roof. When a flat roof expands due to temperature changes or structural movements, the expansion joint stretches to accommodate the movement. Similarly, when the roof contracts, the expansion joint compresses to maintain the connection between the two sections of the roof.

Expansion joints are typically made of a combination of materials, including rubber, neoprene, and thermoplastics. These materials are chosen for their ability to withstand temperature changes, resist ultraviolet radiation, and provide flexibility.

For the majority of homeowners, a home's roofing is a crucial and frequently hated component. After all, replacing a roof is not inexpensive, and when something goes wrong, it can be a tremendous pain and you need an expert roofer to fix the roof or replace it. Before making a choice, it's critical to be aware of the benefits and drawbacks of constructing a flat roof. There are some fallacies to dispel because flat roofs aren't the most common style of roof for homeowners. People may think flat roofs are a poor choice for their property due to some misconceptions about them. The opposite is not always true. Here, we'll debunk some of the most widespread misconceptions regarding flat roofs and examine the benefits and drawbacks of this type of roofing. After reading our article on the benefits, drawbacks, and myths surrounding flat roofs, you should be well-equipped to address the question of how to pick the best roof for your house or place of business.


  1. Installation is quick and simple: Flat roofing systems are very quick and simple to install. This is so because no intricate structures are involved. On the roof deck, the roofing material is spread out and secured. Because of this, flat roofing systems are perfect for new construction projects where efficiency is crucial.
  2. Economical: In comparison to other kinds of roofing systems, flat roofing is frequently much less expensive. For those on a tight budget or looking to cut costs on their roofing job, it is a great option.
  3. Provide an affordable maintenance option: Flat roofing systems are very simple to maintain. There aren't any intricate structures to be concerned about, and the roofing material is really robust. This implies that over time, you won't have to spend much on repairs or replacements.
  4. Provide extra (extra) space: One of the biggest benefits of flat roofing systems is that they give the building's top more space. Storage, an outdoor seating area, solar panels, or an urban garden are all possible uses for this area.
  5. Easy to inspect and repair: Flat roofing systems are very simple to access for inspection and repairs. This is due to the lack of an intricate structure in the way.


  1. As pitched roofs, they are difficult to drain, necessitating the installation of special drainage systems to prevent water from building up on the roof and causing leaks. Without sufficient drainage, water can readily damage flat roofs.
  2. There is less room for insulation on flat roofs than on pitched roofs, despite the fact that flat roofs do offer more space. Weather changes have a greater impact on them.
  3. Less able to support heavy loads: Special supports must be installed to ensure that flat roofs can support the weight of snow, ice, and strong winds.

If you own a flat roof, you're probably aware of its benefits, which include cost-effectiveness, convenience, and safety. However, you may be unaware of the maintenance issues peculiar to flat roofs, as well as the problems that might arise if regular inspections and repairs are not performed. If you observe any of these flat roof concerns, contact a professional roofer to examine, repair, or replace the roof. Flat roof problems include;


Because there is no slope, leaves, branches, and other debris can readily accumulate on a flat roof and clog drainage. Furthermore, a large unkempt mound of leaves traps moisture that can freeze, thaw, and refreeze throughout the winter. This cycle will cause mayhem on the roof below.


Yes, "alligatoring" is a true name for a flat roof that has begun to crack and bubble, like alligator skin. Sun exposure over time is usually the source of this problem and you can't completely turn off the sun. If left ignored, an alligatored flat roof can cause more fractures, leaks within the property, and full roofing system failure.

Ponded Water

Most flat roofs aren't completely flat; they have just enough pitch (or slope) to allow water to drain. However, there is little room for mistakes. If the flat roof is damaged in any way (more on that later), or if ice dams form on it, water can begin to collect in small ponds, leading to more significant problems such as systemic leaks within the home, moss and algae development, and more damage to the roofing system.


Roofs must be resistant to the elements, particularly wind. Even if a shingle or two is blown off a traditional roof, the rest of the shingles are engineered to retain in all but the worst windy situations. Because flat roofs are made of a single sheet of material, a little wind damage can quickly transform into a lot of wind damage with a few more gusts.


Over time, houses settle and move. As a result, the roofing membrane between a home and the roofing material deteriorates. Because the membrane of a flat roof is one continuous sheet, the movement might cause it to buckle. A sloppy flat roof installation can also contribute to buckling, leading to worse difficulties and potentially a roof replacement sooner rather than later.


A leaky flat roof can be caused by ponding water, alligatoring, buckling, or the natural elements. However, leaks can occur even in the absence of these concerns. Damaged flashing, for example, can cause leaks on both a flat and a sloping roof.

Shorter Lifespan

A flat roof should endure at least 15 years and maybe up to 30 years after competent installation. That is a far shorter lifespan than an asphalt shingle roof and even less time than cedar and metal roofs.

All of these concerns may be resolved by contacting a professional roofing company at Astoria Roofing, 29-16 30th Ave Astoria, NY 11102, (718)-285-6273 https://www.astoriaroofingny.com

Here are the reasons why a flat roof is a good choice.

A flat roof is a full roof or nearly level. Still, whilst they're described as flat nearly all flat roofs are frankly laid to a fall to ensure that rainwater can gallop off to the lower side. The flat roof has been available for centuries. If you want proper installation of a flat roof, you'll need a professional roofing company that have experienced roofers working with them, they can install a faultless roof that will last for ages with little to no repair. What's it made of is something you should know.

How Are Flat Roofs Made?

They're made with the same accoutrements as heavily-inclined roofs. The disparateness is flat roofs bear water resistance.

Built-Up Roof is one of the most common flat roofs. It has felt and tenacious layers. It starts with the sundeck board, followed by insulation. After that, layers of asphalt and felt are modified, with clay being put on the top subcaste of the asphalt. The top subcaste reflects the sun, keeping the outside isolated. It also protects the lower layers from weathering. Gravel is easy to replace, so you can pour more on it when demanded.

Also known as fiberglass, GRP roofing is a good pick. The tongue in groove roofing is laminate, which has a unique resin for roofing. GRP lays like barrel. You may require to take a training course, but this roofing is simple to lay than BUR, which requires a certified crew.

BUR uses tar, but bitumen is a replacement. Tar smells bad and is messy. Bitumen uses layers of asphalt with a defensive topcoat of sealant or other defensive material. The best part about bitumen is it comes in peel-and-stick pieces, so it’s effortless to apply. You can get peel-and-stick asphalt that works precisely as well as poured asphalt and is more accessible than other roofing options.

While metal roofing isn't a specifically new conception, some people may not rate it for flat roof construction. still, as two critical rudiments of a business are effectiveness and reduced charges, metal roofs should be considered, especially since metal surpasses numerous roofing accoutrements in life, continuity and sustainability.  Also, metal is known for its resiliency to the rudiments, and when these systems are rightly installed and carpeted, they can repel tremendous abuse.

While it's only a single-bias roofing material, PVC or Polyvinyl Chloride is a heat welded approach to marketable roof types, which results in a penetrable seal. further generally referred to as vinyl roofing, PVC roofs can last up to 30 years. Also, PVC offers several advantages over traditional roofing systems. For instance, these roofs are frequently light in color, which improves overall energy effectiveness.

We at Astoria Roofing are truly transparent about the accoutrements we use and which options are the best for your personalized requirements. Reach out to us at Astoria Roofing 29-16 30th Ave Astoria, NY 11102 https://www.astoriaroofingny.com/.

Are you planning to change your roof in 2022? Has your existing roof reached the end of its useful life, or has it sustained significant deterioration or wear and tear? You might be curious to know about the roofing design trends for 2022 before making any judgments on the roof you prefer. Roofing design, like interior and exterior design, follows many trends that can help your residence look more new, fresh, and beautiful. Three trends you should think about adopting are highlighted below – these roofing trends are not listed in a particular order.

  1. Asphalt Shingles

Asphalt shingles are the most used roofing material, which isn't likely to change in 2022. They are nevertheless quite robust, though not to the extent of metal, and they are more cost-effective, fast, and reasonably straightforward to install for roofers. Explore with color, texture, and finish if you wish to use asphalt shingles; however, give them a stylish appearance. There are various unique choices accessible to property owners in recent times, so there's no justification to stick with what everyone else is doing. Instead of waning into the background, why not make your shingles a focal point on your home?

  1. Metal Roofing

If you wish to look ultra-trendy, metal roofing should be considered while choosing a material for your roof. Although it is not a recent roofing material, it does go through popularity cycles.

Aside from being trendy, there are several reasons why a metal roof can be a good choice for you. They're also exceptionally long-lasting, outlasting regular asphalt shingles by a factor of ten. They can resist strong winds, come in a variety of colors, help to make a residence look more beautiful and elegant, and never absorb liquid. If you're curious about the catch, metal roofing is one of the most costly roofing materials available. Metal will most likely not be feasible if you're on a restricted budget.

  1. Eco-friendly roofing

Lastly, another forecasted roofing design trend for 2022 is the usage of environmentally friendly materials. With so many individuals being careful of the footprint they leave behind, it only adds up to apply this sort of informed thought to your roofing decision. It may still appear beautiful, distinct, and stylish while still being a more environmentally friendly option.

You can explore using recycled or synthetic roofing materials. This could incorporate materials like recycled rubber or plastic. Obtaining details from pros is beneficial once again.

You will be infusing some beauty and class into the outer part of your property by selecting either of these roofing design trends for 2022 highlighted above. The best part is these roofing trends do not only add beauty and class to your property, they also makes the more durable.

If you're looking for where to source for an outstanding rooting company to help install or replace any of these trendy roofing materials, you are just at the right stop.

One of the common problems that have been attached to flat roofs over the years is ponding water. Which is also known as ponding water or standing water.

Due to the inability of a flat roof to drain water, it uses drainage systems, gutters, and drainage lines. In an actual sense, it's normal for a flat roof to have some water especially after heavy rain or during winter. But where the problem lies is when the water stays on your roof for over 48 hours.

Normally, no matter the precipitation, rain, or snow, all signs of water should have left your roof after 48 hours. Now, if by any chance, there is water remaining after 48 hours, then you are dealing with pooling water.

Your next call to action is how to fix it, which is why we believe you are here. Pooling water might not be a major problem at first, but with time, it can expand to become a great problem you might not be able to handle. This is the reason you should solve it while it is small.

Pooling water can lead to cracks and leaks on your roof. It can also serve as a magnifying glass for ultraviolet rays, which causes more damage to your roof.

So, how can you fix your roof when you encounter pooling water?

Fix The Drainage System And Gutters

This is not much surprising though, because for water to drain from your roof, it has to go through the drainage system or gutters. So, if water is not flowing, there is something wrong with the drainage system.

You can fix the drainage system by removing leaves, dirt, debris, etc. Debris looks little at first but can lead to mold, which can block your gutters completely.

Also, there might be a disconnection in the gutters, that is, a break inflow. Which is not allowing the water to flow freely. You can employ an expert or you solve it yourself.

Create A New Draining System

If you cannot solve your current draining system, then you need to create a new draining system. One of the best ways to do this is by creating draining lines on your roof, this allows the water to move in different directions. This is an effective way to fix the ponding water problem on your flat roof.

Replace The Membrane Of Your Roof 

You can solve ponding problems by replacing the membrane of your roof. Although this is an expensive measure, it helps to solve ponding problems and also expand the life of your roof. This should be done by a roofing professional so you won't have similar issues in a few years to come.

Repatch Your Roof

This is arguably the most expensive measure you can take. Your first roof's pitch might be too low for your drainage system. So, you can repatch your roof so ponding water will not resurface.

Except for the cleaning of gutters, others are complicated measures; therefore, you need to contact your local roofer to help you with it. For guidance, quote, and more information, you can contact us at Astoria Roofing, 29-16 30th Ave Astoria, NY 11102, [email protected], 718-285-6273

Sealing your flat roof is one of the best investments you can make as a roof owner. While many homeowners see it as frivolities and a waste of funds, it's worth the investment.

Aside from the fact that it helps the aesthetics of your building, it also protects it from weather conditions like heavy rain, strong wind, etc. Helping you to forgo situations like standing water, leaks, cracks, etc. Which of course, increases the lifespan of your flat roof

The importance of sealing a flat roof has been underrated over the years. This has caused the detriment and lifespans of flat roofs.

Sealing a flat roof is as important as installing it. Aside from decorating the interior of your house, your flat roof should be one of your top priorities. If you want to enjoy your flat roof and use it for a long time before installing another one, then you should install a roof sealant.

The good news is that you can reseal your roof frequently. This means you will enjoy your roof for a long period.

As humans, we tend to ask about the benefit of something before considering and adopting it. We understand that a lot of homeowners like you are not using roof sealants because you don't understand the benefits and importance. Therefore, we put together 3 important benefits of sealing your flat roof

Roof Sealants protect your roof from severe weather conditions and elements

Although a flat roof has some protective elements, they are fragile compared to other types of roofs. Especially, when confronted with severe weather conditions like strong winds, heavy rains, etc. When these weather conditions are continuous, you should be ready for standing water, which will lead to leaks, cracks, and other roofing problems.

But with a roof sealant, the reverse is the case. Even if you are faced with strong weather conditions, your flat roof will be safe and will still last long. Rather than your flat roof getting affected, the roof sealant will be affected instead. Which keeps your flat roof safe.

Improves the exterior and curb appeal of your home

A major part of the home that grabs the attention of onlookers, visitors, and passersby is the roof of your home. Many homeowners disregard this fact but it's the truth.

A roof sealant not only protects your roof from extreme weather conditions but also makes it stand out among competitions. Imagine your home being the center of attention and attraction in your whole area, how would you feel? Of course, you would feel excited and you would be proud of your home. With a roof sealant, you can achieve this.

Increase the value of your home

Many homeowners change the roof of their home so they can sell it off at a higher price. The same applies to roof sealants. If you are planning to sell your home and you are thinking of increasing the value, adding a roof sealant is a reliable option.

Roof sealant makes your roof attractive; thereby, increasing the perceived value, which leads to a higher bargain. And fetches you more money.

So, immediately you add a roof sealant to your flat roof, the value of your home increases. Just because of this, you can attract high-paying bidders to your building.

Now you know the importance of sealing your roof. If you were having second thoughts, this is the assurance you need. And if you already have it, you should consider changing it if it's over 5 years.

To know the kind of sealant that best suits your roof and environment, we strongly advise that you employ the service of a professional roofer in your area. Also, if you need professional advice about roof sealing, you can contact Astoria Roofing at 0ⁿ29-16 30th Ave Astoria, NY 11102, 718-285-6273.

Flat or pitched roof? The argument for which is the best roofing style of choice has been a lingering one for ages. Why the battle continues, there’s no denying that the best choice of roofing material depends on what you need as a homeowner and your local climate.

When building or replacing the roof on your home, there are different roofing materials for you to choose from. Pitched roof consists of different styles like mansard, hipped, or gabled, and various roofing materials, including asphalt shingles, clay, tiles, wood shingles, slate, and lots more. Flat roofs are basically either built-up or single-ply (TPO, EPDM, and PVC). However, what makes them so different? How can you pick the best materials for your home?

Why Flat Roofing Materials Are Different From Pitched Roofing Materials

Flat roofs are not literally flat, as the name suggests. Technically, they are slightly slanted. However, flat roofing can prove catastrophic in climates with heavy downpours of rain due to its poor water drainage ability. With flat roofing materials, you stand at a greater risk of dealing with water leaks, as they have more ability to retain water than letting it run off the roofing system. When the water gets stagnant on top of the roof for a long time, they will eventually find a way to sip into the building, leading to water damage.

Pitched roofs, on the other hand, are designed with high ends and low ends. This allows water to run off the roof to the gutters and down to the ground. Pitched roofing materials are inarguably the best for rainy climates as they pose less risk of water damage.

Flat Roofing Materials Vs. Pitched Roofing Materials


In every building project, the cost is one of the major points people consider. Between flat and pitched roofing materials installation, it is no news that flat roofing materials are cheaper both in material and labor cost. However, flat roofing materials may require more maintenance than pitched roofing materials.

When it comes to deciding according to cost, always consider the short-term costs and long-term costs.


Every roofing system requires regular maintenance to ensure longevity, even with the unending long warranties. Flat roofing materials come with many roofing problems like cracks, leaks, alligatoring, and so on. While flat roofing materials also need regular maintenance, they are immune to different roofing problems common with flat roofing systems.


Lastly, the structure is a critical factor to consider, though it could be subjective. Flat roofing materials offer a variety of styles, stability, and excellent drainage property. They are usually the best choice materials for wet climates. In contrast, flat roofing materials offer more curb appeal and boost the value of your home while still costing less than its alternatives.

Regardless of which material you choose to go with, both flat roofing and pitched roofing materials come with their pros and cons. Always consult with a professional roofer near you to help you determine which is the best option for your home, both with respect to the structure, cost, and maintenance.

It’s no secret that a flat roof is for specialists. So if you’re a homeowner or property manager in New York, you’d know by now that you can’t trust just any roofer to deliver when it comes to flat roofing.

Of course, flat roofs can be quite a challenge when it comes to maintenance and repairs. If the roof of your New York home is leaking or probably needs more than the basic repairs, it makes sense for you to want to fix it as soon as possible. But how do you go about it? Do you give it to any roofer you know to do it, or do you hand the job over to someone your friend or relation knows? Besides, it’s never out of place for friends and family to recommend a “roofer” they know.

Before you hire any roofer to take care of your roof in NY, here are some questions to ask to help you get the best flat roofing contractor.

Do They Specialize In Flat Roofing? How Long Have They Been Installing Flat Roofs?

The critical factor to hiring a roofing contractor for your flat roofing solutions is experience and references. Never hesitate to ask any potential contractor how long they have been in the business. How many flat roofs have they worked on? Also, ask for references. And when you get the references, contact two to three of them to verify. Ask the past clients how satisfied they were with the quality of the work.

While all these may seem to be energy zapping and time-consuming, you wouldn’t want to hire someone that’s not experienced to work on your roof. Or would you?

Are You Certified By Any Professional Roofing Body? Are They Trained And Approved Installers Of The Materials They Fit?

Professional roofing bodies, including the NRCA, have a lot to offer their members, including further training. It’s only wise for any roofer to be an active member of any of these roofing bodies. Roofers that have identified with any of these bodies are already proven to be professionals. Ask for certification to help you determine if you’re dealing with a professional roofer.

And besides allegiance to a roofing body, ensure that the roofer is certified and trained by the manufacturers to install such material. Certification means you’d be getting good prices, better warranties, and even credit facilities for the roofing material.

Are They Fully Insured With Public And Employers Liability?

The next thing you might want to check out is if the contractor is insurance-backed. A reliable flat roofing contractor should be financially protected and have insurance if the employee is injured on the job. However, having insurance is never quite enough. The insurance MUST cover any potential damage on your property during roof repair, replacement, or installation. The roofer should show proof of such insurance.

What Guarantees Do They Give? What Does It Cover? How Long Is The Warranty?

When it comes to flat roofing in NY, a warranty is very important. And beyond just the warranty, the warranty details, including the length, cover, and conditions, are vital.

Flat roofs are pretty easy to get wrong, and that’s why it’s not what any roofer can dabble with. To get the best result, go for a pro. While they are many more questions to ask a roofer, the above should be at the top of the list.
