Standing Water On Flat Roof

In the ever-changing roofing industry, flat roofs are one of the most common roofing designs in urban areas around the United States. Unlike gabled shaped roofs, flat roofs offer a unique form of advantages that gabled shape roofs don’t have. Since most triangular-shaped roof designs are meant to shed water, water damage is easily addressed. However, flat roofs are more prone to water damages since it has a more utilitarian design that’s meant for HVAC and other equipment. That said, flat roofs are quite susceptible to long-term damage from water.

Flat roofs are also susceptible to different forms of damages, most notably, damages from water and fluctuations in temperature. In most cases, these damages are usually caused by the improper way of designing and installing a flat roof. In reality, flat roofs aren’t entirely ‘flat’ but have a slope of around 0.5/12 to 1/12. One of the most causes of long-term water damages to flat roofs is standing water. If water is left to collect on your roof without any means of draining it, this could lead to leaks which can then become gateways to other forms of damages.

But before we can get into what are some of the best ways to prevent water from standing on your flat roof, we have to first look at what are the consequences of

Causes Of Standing Water On A Flat Roof

Knowing the cause of why there is standing water on our rooftop can help you formulate a plan in making sure that your roof is in the right condition.

There Is No Pitch

For most roofing contractors, a flat roof is not entirely ‘flat’ since it will usually have a pitch of at least 0.5/12 or 1/12. The reason for the low pitch is so that water can be directed to one side of the roof and filtered out towards the appropriate drainage systems. However, there are some contractors that overlook having a pitch for roofs. Having no pitch on a roof can trap water since it will remain stagnant on your roof.

Clogged Up Gutters And Pipes

Clogged gutters and drains are a common reason on why leaks form and water gets trapped on your roof. There are different causes of why gutters become clogged up. Most of the time, gutters become clogged because of debris that stuck on the pipes. It’s recommended that you do a thorough inspection of your roof for any source of debris. In most cases, dead leaves and fallen branches can be a cause for clog-ups.

Too Much Roofing Materials On The Edges

Naturally, if you’re going to place too many materials on the edges of your roof, it will serve as a barrier for water to drain out of. It’s best to install drains on the edges of your roof if ever you do have too much material on the edges.


Most people might overlook water as something harmless on your rooftop, but this could easily lead to problems if left unchecked.

Sagging Roof

One of the biggest tell-tale signs that your roof is on the verge of collapsing is that it’s sagging. Standing water can contribute to your roof sagging and warping if it’s not taken care of. Certain roofing materials do not bode well when exposed to extremely lower temperatures. If your roof is sagging, the only way to fix it is by having a roof replacement.

Leaky Roof

Water damages can seep through cracks and gaps on your roof’s surface which can lead to leaks. Once you do see leaks on your roof, it’s best to take action as soon as possible. Leaks can become gateways to more damages as water will erode the surrounding roofing materials near the leaks. Taking action on these leaks can help mitigate any future issues.

Organic And Fungal Growths

Water and moisture are the two main causes of why molds and mildews will form on a roof’s interior. If you ever see your ceiling sweating or having dark stains, then this is a tell-tale sign that there is organic growth. Molds, mildews, and mosses can damage your roof over time as it absorbs the minerals that make your roof durable.

Accelerated Deterioration

Normally, flat roofing materials will usually last 2 – 3 decades. The life expectancy of each roofing material will ultimately vary depending on the level of care and maintenance that’s being done. Having standing water on your roof can form rust on metal beams and rotting on wooden supports. This could lower the lifespan of your roof which could have lasted for 2 – 3 more decades.

Actions You Can Take On Your Flat Roof With Standing Water


The best course of action against standing water on your flat roof is by looking at what is the cause of the problem. If the standing water is mainly caused by a clogged up drainage system, it’s recommended to clear it up. If your drainage pipes are too narrow and can’t accommodate the amount of water that’s being flushed out, then you can widen it. In most cases, thick foliage close to your roof can also be a reason why your gutters are being clogged. Cutting down branches that is close to your roof can help make sure that debris does not fall on your roof.


If you’re not confident in your skills in clearing up clogged gutters, you can always call your local roofing contractor. Having a professional work on your roof can help mitigate any future damages that might happen on your roof. But if you are confident that you can address these damages yourself, you’ll need to consult your roofing contractor first on what’s the best course of action. You should take photos of the damages and the specific area that has water damages.

The Right Roofing Contract Terms and Conditions

Finding a contractor with a good reputation is easy: ask a few friends and a name is sure to pop up right away. While it is only fair not to discredit these recommendations, it is just as important to get to know who you are working with and what contract you enter in. This is very important as it protects you and the other parties involved should anything goes wrong with the project and with its output.

Looking For A Good Contractor? 


Any legal document can be daunting for most of us but when it comes to roofing installation or maintenance, the materials to be used should be highly considered as it determines not just the cost but its durability as well. Make sure that every material is jotted down in the contract as this also allows you to look into complementary renovations in the future.

Project Timeline

Once the materials are ready, it is now the appropriate time to look into the timeline of the project’s duration. This ensures that the crew is bound to follow a specific schedule which includes the number of hours the crew should render in a day (their logged time in and out) and other concerns such as working beyond a certain time. In addition, this also ensures that a special consideration shall be laid out in case of a delay to prevent unnecessary misunderstanding between the parties.

Cost and Payment Plans

If there is one thing that is sure to fuel a transactional fire, it’s one thing – added expenses. These costs can be due to events that are beyond anyone’s control such as an emergency, an accident or simply a miscalculation of the costs. This can be frustrating as it begs the question of whose shoulder should be held liable. Fortunately, most homeowners and other clients can save themselves the dilemma by clearly stipulating it in the contract. These serve as a guide on the next step should a crisis arise during the project. 

Plan B – Changes

Sometimes, a perfectly laid out plan can seem like a nightmare once a simple thing that needs to be changed leads to a domino effect which in turn can lead to a maze of confusion.  Unforeseen damage to the roof may require a different level of care, materials or may ultimately change the time frame that it needs for the roof to be up and functioning. These cases can definitely make us fret but change is not a bad thing either as long as clients are fully aware of the necessary deviations from the original plan with the least impact on the projected timeline.


Though professionals work with the utmost care, a few debris here and there may inevitably fall to the ground from time to time and affect the beauty of your garden or the clean cuts of your lawn. The property damage does not ever compensate for the sturdiness of your roof and this is precisely why a good warranty should be found in the contract as there are always steps on how to deal with these damages.

Home Access

It is quite understandable that most homeowners do not feel comfortable with letting anyone inside their homes for security measures. However, the crew should be allowed access with entry limitations. It is then relevant to keep the crew oriented on the areas where they are allowed to pass to avoid trespassing.


What use is a highly detailed contract if the contractor he or she is unlicensed? It is true that a piece of ID does not equate to one’s skills but it is always better to be working with someone that is highly credible in their field of work as it ensures a quality outcome. Furthermore, each state has its own legal guidelines so it is highly recommended to check it out to see whether or not the contractor is in compliance with the said regulatory principles.

 The inconvenience of going through a contract with its seemingly endless definitions of legal terms and conditions may be overwhelming for a lot of clients who have no experience in it but this is quite significant as it saves and prevents you from the long-term nuisance that may be more difficult to handle. It is always suggested to go through the contract twice or more to ensure that each term is well understood and as with any other documents – don’t forget to read the fine print before signing.

roof shingles flapping in wind

What To Do When Roof Shingles Flapping in Wind

Shingles are one of the most prevalent roofing materials that you can find in the market. Not only are these materials easy to install, but they can hold their own against high winds and heavy rain. However, this is not always the case as the wrong way of installing your shingles inadvertently lead to more damage to your roof.

Sometimes, high winds and storms can be hard to predict and could damage roof shingles if they are not installed or maintained correctly. What could be the reason why shingles flap in the wind? Is there any way that I can remedy this? 

But before we get into anything else, we have to first discuss why shingles flap when exposed to high winds. 

Why Do My Shingles Flap?

There are two ways that roof shingles resist winds, first is through the nailing pattern. When shingles are being riveted in place, it’s going to be hard for wind to uproot it. The second way is through roof sealants. Both are great at making sure that water does not seep towards the gaps of shingles, but most are still susceptible to deterioration from age. 

Check Nailing Patterns

Normally, nails don’t degrade when exposed to rain or high winds, but it can become dislodged and out of place. In most cases, this is due to an error in the installation process or erosion around your shingles. Nails that are used to rivet in place flashings, shingles, and other structures in your roof might last years to decades, but it can still deteriorate when faced with the constant flow of water and fluctuations in temperature. 

It’s best to have a local contractor look at your roof for any nails that are out of place. This can be one of the major contributions to why shingles will flap when exposed to wind.

Check Your Sealings 

One of the reasons why shingles flap uncontrollably is when they’re installed during colder seasons. Usually, sealants that are exposed to lower temperatures will take several weeks before they settle and become good adhesives. 

Aside from the improper way of installing sealants, the deterioration of sealants based on the age of the adhesive can also be a factor. As the sealants and the shingles age, the bonding matrix of the adhesive becomes less potent and will weaken over time. The fluctuation of temperatures could also lead to the weakening of sealants since most roofing materials expand and recede in warm and cold temperatures. 

The best time to seal your shingles is during warmer seasons when your sealants can activate in a shorter span of time. UV rays and the heat of the sun can also help your shingles expand which can give you a clear and accurate measurement of how your shingles will look when expanded. Sealants that are installed during colder temperatures might have bonds that will become weak when exposed to higher temperatures. 

If you’re not up for the task of resealing your shingles, you can always contact a professional roofing specialist to do it for you. Most of them offer different varieties of sealants and sealing services. 

Prolonged Storage 

Since most shingles are susceptible to cold weather and low temperatures, contractors and homeowners tend to store them for a long amount of time. For homeowners that are planning on installing during colder seasons, Warehouses that store shingles need to have the right temperature and humidity to make sure that the roofing materials do not become brittle. Too much moisture could also lead to shingles forming molds and mildews. 

Will Roof Shingles Lift? 

But don’t worry, moderate to strong winds will not lift your shingles if your roofing system is sound and secure. If high winds will not be able to penetrate your roof’s interiors and inside your home, there’s little chance that shingles will be propelled. 

To make the long story short; the reason why shingles flap when exposed to strong winds is that it’s not installed correctly. It might be because your local roofing contractor overlooked certain parts of the installation process, you did the installation yourself without proper professional supervision, or they simply don’t know what they’re doing. To make sure that your roof shingles are installed the right way, it’s best to look for a professional roofing contractor. Moreover, it’s best to do your research first on the track record of your contractors first before commissioning them into service.

Additionally, you can always consult your roofing material manufacturer if the warrant for your shingles remains valid after man-made errors. In most cases, warranties will cover damages caused by man-made errors during the installation process.

pewter gray vs charcoal shingles

Comparing Pewter Gray VS Charcoal Shingles

Starting fresh by replacing and repainting an old roof by having a new one can be one of the most satisfying things in life. Just like having a new car with a new paint job, painting your roof with a new color can easily help you start fresh and clear your mind.

However, having an attractive roof doesn’t guarantee that it’s going to be sturdy and hold off the forces of nature. You might have the best looking roof in the neighborhood, but it will all for naught if your roof can’t hold down your house and protect it against rainwater, snow, hailstorms, strong winds, and updrafts. It’s best to carefully consider your roofing material before making any decisions on what color scheme you want to choose for your roof. 

But before we get into what’s a better choice of color between pewter gray or charcoal shingles, we have to first weigh-in on the different factors that will affect your roof. 

Function Over Design

Obviously, your roof was designed on keeping water, snow, and other debris away from your house’s interiors and far from your house’s foundations. Sure, the color and design of your roof can leave a lasting impact on visitors and passers-by which can increase the value of your home, but the true test is on its strength in withstanding the forces of nature. 

An ideal roofing system should be a combination of both high-functioning roofing materials that stand the test of the environment while still looking aesthetically pleasing. But at the end of the day, the function will always be more important than design. 

Durability and Longevity

Just because a certain roofing material looks good, doesn’t necessarily mean that it will last a long time. Most homeowners see a roofing material and will immediately buy it from the local builder’s depot once they see that it’s compatible with their rooftop. One thing that homeowners should always weigh-in is the lifespan and the strength of the shingles. Even though most shingles are designed for rain, snow, and strong winds, they are still quite susceptible to hailstorms, high winds, and other elements of the weather. It’s best to keep this in mind whenever you are looking for the right materials. 

Moreover, investing in cheaper roofing material can save you money in the short-term, but you will be spending more in the long run when you’ll have to contact your roofing specialists for repairs and replacements. 3-tab shingles and architectural shingles have different unique lifespans and characteristics but 3-tab shingles are generally cheaper and won’t last long.

A good way of determining if the shingles are durable is that it will have a longer coverage for the warranty since shingles that have a more hefty price tend to be more durable and long-lasting. 

If you’re not sure whether a certain roofing material will last longer and will work well with where your house is situated, then you can always consult a professional roofing specialist. 

Exposure to Wind

In states that are located in the southern part of the United States, hurricanes and storms are quite prevalent with winds reaching up to 130 miles per hour. With winds that strong, it can easily uproot and send a roof flying off. Homeowners are highly encouraged to choose shingles that have a wind rating of 130 miles per hour if they want their roofs to still be intact. 

Wind rating is especially important since an uprooted roof will not just be dangerous to your home, but also to cars and other inhabitants from other homes. Shingles that are propelled at very high speeds by hurricanes and typhoons can be lethal. 

Pewter Gray vs. Charcoal Shingles

An easy way of determining if a shingle is pewter grey or charcoal is by the shade. Normally, pewter has a lighter shade than charcoal. Metallic pewter shingles are able to reflect more light. In turn, it appears as a lighter grey. On the other hand, charcoal has a deep shade that borders from dark gray to black. 

Ultimately, the paint that you will use for your roof will depend on your personal preference. Most individuals would choose pewter grey since the different shades of gray can make it look classy while most would also choose charcoal-colored shingles since it can easily hide dirt and can absorb heat if you want to retain heat on your roofing Alexandria VA and house.
