Why is my flat roof leaking?

by: Kirsten Land on April 2nd, 2019 about Commercial Roofing, Roofing Advice

 When a flat roof starts to leak, many people will simply think water is pooling on top of the building. But standing water is just one of many factors that can contribute to a leaky flat roof. 

That being said, it is a good idea to check for leaks and pooling water on a flat roof after heavy rains. As a roof settles and changes shape over time, the chances of standing water increase. Standing water puts extra pressure on the roof and deteriorates the roofing materials.

Many issues may result from a settling and aging roof: flashing leaks, buckling, or alligatoring. Yes, alligatoring.


Flashing is the material used to seal off the area between any flat roof surface and any non-flat surface on the roof. Basically, it covers the gaps and cracks at the edges of things on your roof. Over time, a roof’s flashing may start to pull away, peel up, crack, or tear which can lead to leaks and moisture seeping into the building below.


Buckling relates to the asphalt membrane of the roof, and it’s another issue that arises due to excessive movement from a settling roof over time. As a roof gets older, the asphalt membrane may wrinkle or buckle. A buckled roof is not a healthy roof, and it’s a sign that your roof needs maintenance.


This happens when asphalt used on a roof wears out and starts to crack and bubble and take on an appearance that resembles the bumpy skin of an alligator. A roof alligator can’t bite you, but if you ignore the issue, it will certainly feel painful one way or another.

A professionally installed flat roof can last anywhere from 15 to 30 years. But there are obviously many factors that can impact the health of your roof. High amounts of rain, wind, ice, hail, and flying debris will eventually harm any roof. 

The best approach to prevent leaks in a flat roof is to monitor the status of your roof. If you are concerned by something you see as a potential problem, have leaking issues, want to start a maintenance program, or just have some questions, feel free to contact us for a consultation.

In the early years of Land Roofing Enterprises, we only offered roofing services. Brian did the labor along with roofing crews we hired. However, that created a challenge in managing the day-to-day duties of the business plus overseeing roofing crews plus estimating new jobs. Many other roofing companies were using subcontractors for their labor, so we decided to look into that option.

Helping with more than just the roof

As our business grew, clients also began asking for help with other aspects of their insurance claim, such as guttering, siding, windows, painting, and fencing. Our clients trusted us and valued the quality of service we provided. They wanted us to help them with more than just their roof.

We wanted to provide the highest quality of service to our clients, so we began developing relationships with companies who could provide the other services that often went along with an insurance claim. Instead of the customer having to work with multiple different companies on different pieces of the claim, we began offering a one-stop-shop approach to clients.

We communicated with the customer and their insurance company, and then we handled all of the subcontracting for other services. It made the process much easier for our busy clients!

That’s the business model we still use today. It’s a smart move for our business, since we can tap into different subcontractors as needed for specialty jobs or high-volume periods. Plus it’s the right thing to do for our clients.

Maintaining high standards

We have high standards for quality at Land Enterprises Roofing, and we expect those same high standards from all of our subcontractors.

We require that they hold a specific level of general liability insurance and worker’s comp insurance as well. That protects us and our clients, plus the subcontractor’s employees. We also stay in close communication with our subcontractors on any job to ensure they provide quality work. If a problem arises, we work with them to correct it and ensure we always meet the client’s expectations.

Many of our subcontractors have been working with us for a long time. Our roofing subcontractor has been working with us for more than a decade! We take good care of them and they take good care of us by providing the best possible service for our clients.

Five common flat commercial roofing problems

by: Kirsten Land on March 17th, 2015 about Commercial Roofing

Flat commercial roofWe’ve been in the commercial roofing business for more than two decades. We’ve see a lot over the years and know a thing or two about good commercial roof installation and upkeep. To the untrained eye, the process looks simple enough from the ground. But that’s deceptive.

There as much craftsmanship and skill needed to properly care for a flat roof as some of the most interesting looking roofs you see on homes today.

Five of the most common problems we encounter with flat commercial roofing are:

  1. Leaking – Drainage angles are more subtle than a pitched roof.
  2. Poor Installation – Get the angles wrong and there will be trouble.
  3. Lack of Maintenance – Wind, rain, hail, and even time take their toll on the best roofs.
  4. Pooling of Water – Assuming it was property installed, as the roof ages, problem areas can develop.
  5. Improper Repairs – Do it right, or don’t spend the money. Taking an aspirin for a broken bone might relieve the pain a little, but it doesn’t fix the problem.

A challenge for owners of structures with flat commercial roofs is that inspection can be difficult, if not impossible, for the owner. Even when you can make your way to the roof, knowing what to look for can be tricky. Seeing a dry roof, or one without visible dips, does not necessarily indicate a healthy roof.

Some of the things we focus on when looking at commercial flat roofs include:

  • Inspect all rubber plumbing boots and replace as needed.
  • Inspect all attic vents for cracking, flaking and metal rusting.
  • Inspect for animal damage or roof penetration.
  • Inspect shingles for curling, cupping, flaking, tearing, splitting and blistering.
  • Check for buckled roof decking.
  • ...and more.

Regardless of who you hire to replace, repair, or maintain your commercial roof, there are a couple questions you should alway ask.

What is the Certification Process?

Is your contractor certified to put on the type of roof you need? Not every roofer is. It’s important to know your roofer can handle the job well, and that they will stand behind the work.

What is the Warranty Process?

We often think of a warranty as something you pay a little extra money for at check out. A commercial roofing warranty is a little different. You want to make sure the roofer stands behind the work, but you also want to make sure the manufacturer of the product used stands behind their product.

Even though we are certified, we also adhere to an exceptional warranty process. Our manufacturer will come to the job site and inspect the work. Most times, we pass with flying colors. Occasionally though, the inspector will find something that’s not quite right with how the product was installed. When humans are involved, mistakes can be made. We correct the issue immediately and confirm with the inspector that the roof now meets all quality standards. At Land Enterprises Roofing, we stand behind our work from start to finish, and beyond!

With the added inspection (insuring the warranty will be valid) the property owner can rest easy knowing his/her new roof meets the standards required...not only for our manufacturer, but also for the insurance company.

Do you have questions, concerns, or need a certified professional to take a look at your roof? Give us a call today!

How many roofing quotes?

by: Kirsten Land on December 16th, 2014 about Commercial Roofing, Residential Roofing

EstimateBefore insurance adjustors came along, you would need three estimates to verify there is actually damage to your roof. Today, insurance companies have their own employees and subcontractors to examine your roof and report on the extent of the damage.

So are three roofing quotes still necessary?

While some insurance companies may request three quotes, it’s not really necessary anymore.

And if you’re thinking you should price shop to get the best rate, think again. You don’t need to go with the best price because your insurance company will negotiate rates with the roofer of your choosing. Remember, they’ll be the ones paying for it, not you.

Simply select a local roofer who you trust, and the insurance company will negotiate the rate based on the price list they have to follow. The insurance company and the roofer will negotiate how many shingles the home will need, determine if a layer of shingles will need to be removed, if decking will need to be replaced, etc. It’s those fine details that the insurance company and roofers need to work out between each other.

We’ve been telling everyone to pick someone you’re comfortable with and trust. If it’s us, we’ll meet with the insurance adjustor show them the damage and make sure everything will covered under your insurance.

The other day we had a customer who owns several rental properties with a warranty shingle issue. We alerted the manufacturer to the problem, gave them our bid and the homeowner decided to price shop. He got another bid which came in under ours. We made some adjustments to our bid but explained to him not to worry about the price. Just pick the company you trust, send in the bid and the roofer and the manufacturer or insurance company will work it out.

It’s important to remember that you’re not paying for your roof. When you price shop, you’re hassling yourself, wasting your time getting bids, and wasting roofer’s time. Roofing companies will work out the claim on your behalf. So, go with someone you know, someone you like and someone you trust. It’s really up to the roofer and the insurance company to work out the pricing aspect.

If you have any questions about insurance coverage, please give us a call at 405-359-3951.

Cold weather roofing

by: Kirsten Land on December 2nd, 2014 about Commercial Roofing, Residential Roofing

Snow on roofMany people find themselves in need of roof work in the colder months. But often they wait until warmer months to get it taken care of. So is roofing during winter not a good idea?

The truth is there is plenty of roofing activity taking place in the winter. You don’t have to wait until the hectic spring tornado season to do a complete re-roof.

In fact, even though we’re working, roofing contractors are a lot less busy in the winter than in the spring or summer. That means you don’t have to wait to have your roof repaired or replaced by the company you really want to work with, like Land Enterprise Roofing.

We are always careful to follow specific guidelines when we roof a home during the winter. Luckily, Oklahoma tends to have milder winters. As long as the day is forecasted be sunny and get above 50-degrees, we can install a roof. In the winter, a residential home’s heating system and attic airflow will warm the roof to 10-15 degrees above the outside air temperature. Additionally, if a roof has full sun exposure for the entire day, the heat from the sun on a dark roof will provide enough warmth to seal the shingles.

In the morning, our crew will tear off shingles and attach the underlayment to the decking. Then, we will place the shingles on the roof to allow them time to warm up while the crew heads to lunch. On a 50-degree day, the shingles will warm up to a 70 degrees. In the afternoon, the roof will be warm enough to secure shingles to the decking. The warmth of the sun will help the shingles lie down and seal into their permanent position.

Of course it’s entirely up to you to choose when to complete projects on your home but you don’t have to wait until spring to begin your roofing project. The key the winter roofing is to evaluate all variables before work can begin. Our experienced team knows when the elements are optimal for winter roofing projects. Call and schedule your roof inspection or project today!

How to choose a roofer

by: Kirsten Land on November 4th, 2014 about Commercial Roofing, Residential Roofing, Roofing Advice

1 - ChoosingChecking the yellow pages under “Roofing” really isn’t the best strategy for choosing a reputable roofer for your home. With the advent of the internet, any responsible home owner should do their research before signing a contract with a roofer. It’s your job to ensure the company you hire is reputable and capable of getting your roof done right the first time.

When shopping for a roofer, start by asking friends and neighbors for reputable references. You can also do some simple internet searches and check online reviews of roofers in your area. Your goal is to identify 3 to 5 roofers to conduct research on.

Step 1 - Do your research

These four steps should help you narrow down you search to 2-3 companies.

Step 2 - Ask for proof of the following:

  • Business License
  • Roofing credentials
  • Workers compensation insurance
  • General liability insurance for at least $1 million
  • Written manufacturer warranties

Step 3 - Get an estimate

  • Ask if there’s a charge for an estimate (there shouldn’t be)
  • Unscrupulous repair companies may use a teaspoon, small rocks or hammers to fabricate damage. Don’t allow someone on your roof without keeping a close on them at all times.
  • Iron out all the details of installation
    • What is the exact roofing process from tear off to completion?
    • What brands of materials will be used and what does the warranty cover?
    • What’s the timeline?
    • Do they warranty their work?
    • How will bushes and plants be protected?
    • How will trash b disposed and nails cleaned up? Where will dumpsters be placed?
    • Never work with a roofer who asks you to pay for entire job upfront. A deposit of one-third is standard procedure. Never pay with cash.

Step 4 – Request local references and ask them the following questions:

  • Would you use this roofer again?
  • Did the roof leak? If so, did the roofer respond promptly, was he courteous and did he charge you for any additional work?
  • Did the job come in on budget? If not, by how much did he exceed budget? Were the extra charges justified?
  • Did the roofer damage any bushes or flowers, and did he leave nails in the driveway?

After you feel confident you’re made the right decision, request a formal contract and make sure everything you discussed during the estimate is in writing.

If you have any questions about how to choose a reputable roofer, we’re happy to guide you through the process – even if you don’t choose us. Give us a call at 405-395-3951.

Commercial roof maintenance for your business

by: Kirsten Land on October 7th, 2014 about Commercial Roofing

Metal roof backgroundAs Oklahomans, we know severe storms aren't a matter of if – it's a matter of when.

The roof is a commercial building's first line of defense from natural hazards such as wind, rain, fire, hail, ice, snow, and extreme heat. It is also the most vulnerable part of your building.

Every day, your roof is exposed to weather and other elements that may contribute to decay and deterioration, increasing the risk of damage to the roof itself and the contents below it.

Proper maintenance prolongs the life of a roof and in many instances will allow for "repair" instead of "replacement" when a problem is identified.

We are here for our customers through the entire life cycle of roof ownership. Most owners are not aware that properly maintaining the roof can actually extend the life of the roof and minimize the entire life cycle cost. A proactive approach to roof maintenance will allow you to anticipate future roofing needs and plan your budget accordingly.

Here are a few signs that you may need a roof maintenance plan sooner than later.

  • Unexplained mold or odors inside the building
  • Water stains on the ceiling
  • Standing water or ponding on the roof, which can weaken the roof deck
  • Bubbles in the roof cover, which can reduce effectiveness against uplift forces in a windstorm
  • Tears in the roof cover
  • Gaps in roof flashing (strips of metal where the roof meets the wall or object the protrude from the roof)
  • improper sealing around skylights

We conduct a full 12-point roof inspection twice a year: before winter and after winter. We clean debris off the roof and gutters, clean the skylights, and take care of any caulking that needs to be done. We want your roof to be clean and working properly before winter because water and ice can get in there and cause a lot damage to your roof, masonry, or any other material.

We also keep trees trimmed. This prevents branches from rubbing against the roof and leaves from accumulating on the roof and clogging drains and gutters. Additional aspects of our 2-point bi-annual roof inspection include checking:

  1. Ventilation
  2. Exterior
  3. Gutters
  4. Drip Edge
  5. Underlayment
  6. Valleys
  7. Flashings
  8. Skylights
  9. Chimneys
  10. Decking
  11. Ridge
  12. Shingles

As business owners, you face challenges in the day-to-day maintenance of your company operations and your building facility. Which is why we offer a commercial roof maintenance program for businesses. When it comes to your first line of defense against severe Oklahoma weather, it makes sense to hire a contractor to make sure the job is done safely and correctly.

For more information about our preventative commercial maintenance plans starting at less than $200 per year, call us at 359-3951.

The danger of nail guns

by: Kirsten Land on September 2nd, 2014 about Commercial Roofing, Residential Roofing

Pneumatic roofing nail gunYou probably haven’t spent much time thinking about how your roof was installed. It’s shingles and nails, right? What’s complicated about that? Well, there’s a little more to it.

If you’ve ever had a shingle fly off your roof after a storm, it could be because your installer used a nail gun instead of hand nailing your shingles.

Nail guns are popular because they shorten training time and reduce effort. It takes time and practice to become proficient at hand nailing, while nail gun productivity can be achieved almost immediately. In spite of this apparent advantage, we hand nail all our shingle roofs.

The main reason is that we have more control over the depth of the nail, which must be flush with the surface of the shingle. This means the nail can’t be over-driven or under-driven.

Roofers who use nail guns will start the nail gun compressor in the morning, at the beginning of the day. Of course as the day goes on, the temperature gets warmer and the installer needs to adjust the pressure to compensate for temperature variations. What ends up happening is the installer doesn’t adjust the compressor because it’s a hassle to frequently go up and down the ladder. Instead, they’ll usually set the compressor extremely high which drives the nail too deep into the shingle. This also saves time for the installer who would normally have to hammer raised nails to “finish.”

Unfortunately, over-driven nails tend to blast completely through the shingle, creating a problem that remains unseen until high winds test the installation. Six flush nails are required to achieve a wind rating of 130 mph. If any of the nails are under-driven, you’re going to lose shingles in the next wind storm. It’s a big problem in Oklahoma because of our high winds.

Sometimes installers who use nail guns will compensate by increasing the amount of nails per shingle. However, this just increases the amount of deck penetrations which weakens the shingles over time due to thermal expansion and contraction.

The ideal nail placement is limited to a very small area. When a nail is driven outside of that area, the shingle’s wind resistance is reduced and the manufacturer’s warranty may be invalidated. Shingle manufacturers have certain guidelines they want installers to follow. They’re very particular about how many nails go into each shingle and the placement.

Proper nail placement is certainly possible when using a nail gun, but tends to be considerably more accurate when hand nailing.

That’s because with hand-nailing, you can feel when the nail misses a board. It’s a feeling you don’t get when using a nail gun. Nails driven between boards are more likely to be overlooked, which will cause raised shingles or leaking.

A lot of our installers are so used to hand nailing that it’s a comfort issue for them. They can feel when the nail is in the right place and they’re more confident in the work they do. They also have the skill and practice to hand-nail quickly. It’s intuitive after a while. They know where it’s supposed to go and what it’s supposed to look and feel like.

Sure, it takes a little more time for new installers to get trained on hand nailing, but we really feel it’s well worth the time and effort to ensure we’re building quality roofs that will withstand most anything Oklahoma weather throws are at.

If you’re interested in learning more about our roof nailing process or would like a quote, please contact us at 359-3951.

Did you lose your roofer?

by: Kirsten Land on August 5th, 2014 about Commercial Roofing, Residential Roofing

Truck Driving AwayWe've received an unusual increase in new clients this year.

That should be a good thing, right?

Well, a lot of calls are coming from real estate agents, contractors and new homeowners who lost their roofers. Storms in Oklahoma haven't been as severe this year, so roofers have been leaving the state in search of better opportunities.

For some roofers, it's how they operate their business. They'll storm chase, enter an area where severe storms are and within a day they'll have a shop completely set up and running. It's actually incredible how fast they work.

They'll rent a small space month-to-month and move in immediately, put in a desk, a phone and a receptionist to schedule appointments. Then they'll have some business cards printed and have their crew to go door to door selling their roofing services.

Other traveling roofing crews operate their business in a similar manner; they'll get hired on by long-standing roofing companies when there's a significant influx of work.

We don't hire these kinds of roofers. When a storm blows through and we have more business than we can handle, we hire one of five crews that we've worked with for over five years. They're all licensed and insured and have proven themselves with us. We are confident in their abilities.

Not surprisingly, some of the roofers who have left the state are travelers and it's expected that they would move on to greener pastures. But, we've heard of several well-established roofing companies who have moved their whole operations elsewhere.

It's shocking news to us, too!

Land Enterprises Roofing has grown by creating relationships with our clients and earning referrals. The relationships we've built with this community are extremely important to us.

Roofing companies and crews come and go, but we've been here since 1986. So, needless to say, we're not going anywhere! You can trust that we're in it for the long haul.

If you have any roofing needs or are interested in our maintenance plan, give us a call at 405-359-3951.

Pipe and roofEven the most expensive, highest-quality roof in the world can be ruined when a roofer or home owner cuts corners on ventilation. It's something that's easy to overlook and ignore, especially when you're not up in your attic or on top of your roof very often – if at all.

The extra dollars you spend on ventilation are paid back by the cost savings on your utility bill and the extended life of your roof.

A problem for all seasons

When a roof isn't properly ventilated, condensation will build up and potentially cause rotting in the roofing materials as well as the roofing deck and support beams. This can happen anytime during the year.

In summer, poor ventilation will also keep hot air trapped in your attic and increase your utility bill. The increased heat will also shorten the life of your roof.

Ventilation is also an issue during winter. Warm air trapped in your attic can melt the snow and ice on your roof everywhere except for the eaves. When this happens, melted water will build up behind the perimeter ice and soak under the shingles and into your house. When these ice dams collapse, they can also rip off shingles and gutters.

Even though some roof vents come with winter covers, it's usually a bad idea to use them.

Staying in balance

Too much venting can be a problem too. A properly ventilated attic will be a negative pressure zone – outside air will be pulled in and hot air continuously expelled. Too little venting and there won't be enough air flow.

But if you have too much venting there won't be any difference in outside or inside air pressure and air won't flow through at all – rendering all your vents useless. Any unnecessary openings in your roof can be a source of leaks and animal access – so it's important to find a middle ground.

There are all sorts of options when it comes to roofing ventilation – powered fans, passive fans, under-eave soffits, ridge vents – but the right combination depends on the unique characteristics of your roof. Your roofer should be able to recommend the right ventilation solutions for your particular situation.

Have questions?

If you'd like advice on ventilation for your roof, we'd be happy to help. Give us a call or e-mail and we can visit with you to determine your ventilation needs.
