Roof Decking: Rotting & Corrosion

July 18, 2019 by Infinite Roofing Leave a Comment

Owning a home is one of the most challenging, yet rewarding responsibilities a person can have. You get the chance to establish a sanctuary for you and your family that provides the protection and comfort you desire. However, this can all be put at risk when you begin to notice issues with your roof such as a couple of wet spots on your ceiling. This may be your first home and may have never even looked at a roof’s foundation before let alone knowing where to begin. You go up to your attic to investigate, and come upon a distinct musty smell of mold. Signs would point to a roof leak, and one of the main causes usually would be roof rotting or roof corrosion if you own a metal roof. What do you do? You may not be an expert in roof contracting, but that is why certified experts like us at Infinite Roofing are here to help you get back to living with the protection and comfort you deserve.

What is Roof Decking?

When talking about roof rotting, we are talking about the roof decking or sheathing of the home. The roof decking plays a pivotal role in determining the safety and structural integrity of your roof.

Roof decking is the foundation of your roofing system. It is the base layer that connects the roof to the home. The roof deck is placed between the structural components, such as the trusses and joists, and the insulation/weatherproofing layers. When it comes to your roof rotting, you want to take all the steps necessary to ensure the health of your

Roof Decking Materials

Roof deck materials come as 4 x 8 sheets in a variety of different material options. The most common type of roof deck material is plywood, which comes as either OSB (Oriented Strand Board) or CDX (C to D Exposed). Other roof decking materials include steel, concrete, and cement. The main determinant of the type of material you should use is based on the amount of weight that the roof deck will need to carry, plus the weight of air conditioning equipment, rain and snow. For most residential projects the common choice of roof deck materials are OSB or CDX plywood. For commercial projects, steel, concrete, and cement are more commonly found in the roof deck. These materials are definitely interchangeable depending on your project requirements, however for now let us focus on three main materials; OSB, CDX, and steel.

OSB Plywood

OSB (Oriented Strand Board) was originated in the late 1970s as an extended use of waferboards. It separates itself from other wood-scrap materials because the long strips of wood are placed strategically instead of randomly, hence the name “oriented” because the wood strips are oriented strategically to improve the strength qualities from the waferboard. OSB Plywood is made from heat-cured adhesives and rectangular-shaped wood strands that are arranged in cross-oriented layers. Because OSB uses small wood strands for production, it is considerably less expensive than standard plywood. When produced in large, continuous sheets, the OSB is a sold-panel of consistent quality with a few voids or gaps. OSB Plywood is more susceptible to absorbing moisture and swelling up than CDX, due to the release of compaction stress in OSB created during the pressing of wood chips into the panels. Swollen OSB will remain permanent, to a degree, causing leaks, increasing decay, and creating uplift of whatever materials lie above.

CDX Plywood

CDX (Class C to D Exposed) Plywood is the lowest class of plywood and is often used in the construction industry or as a base to create other materials. Plywood is made from thin layers of wood that are peeled from a spinning log, called veneers, that are cross-laminated and glued together with a hot press. Throughout the thickness of the sheet, the grain of each layer is laid perpendicular to the adjacent layer. The final product is an odd number of layers so that the balance is maintained around the center. Since CDX is made from whole layers of logs as opposed to small strands, the plywood is much more consistent and has a less rough appearance than OSB. CDX is lighter than OSB, retains nails and screws better than OSB, and produces less swelling when exposed to water and will return to its normal thickness after drying. This feature alone is enough for roofing contractors to prefer using CDX Plywood over OSB for their roof sheathing.

Steel

Steel or Metal Roof Decks have been around since the 1930s/40s. The Steel Deck Institute (SDI) has been the biggest force in setting the standard when it comes to the design, manufacture, quality control and construction practices applied to cold-formed steel decking. The steel deck is roll-formed from structural quality sheet steel and is made to span over the roof joists or purlins to provide a flat surface to apply the weatherproof roofing. The variations in its thickness, shape, and depth can be used to meet the variety of loading requirements and spans. The steel deck’s versatility also allows for it to be used in more unusual configurations that may be sloped or curved. Steel decks are usually more costly than materials like plywood however, they provide increased longevity, durability, and a better strength-to-weight ratio backed by years of proven satisfaction in the roofing industry. Steel decks are more commonly used for flat roofing systems, which are typically used for commercial roofing projects.

How Can I Tell When My Roof Is Rotting/Corroding?

As a homeowner, you want to do anything that you can to keep your home safe from the elements of mother nature. Your first line of defense is your roof, so how can you tell when your front line is starting to deteriorate?

First things first, is it even safe for you to check your roof? We do not recommend grabbing a ladder and going on your roof to do an inspection. According to the American Association of Orthopaedic Surgeons, last year there were about 500,000 ladder-related injuries due mainly to homeowners trying to clean out their gutters or perform their own roof inspections/repairs. Our team of certified roofing contractors have specific equipment and years of experience in doing roof inspections safely and thoroughly and will provide a free, no-obligation estimate for any repairs or replacements needed.

With that being said, there still are some telltale signs that you as the homeowner can check for yourself to see if an estimate would be needed.

Roof Rotting

Here is a list of signs that your roof deck may be damaged or rotting:

Shingles curling, cracking, or buckling
Missing shingles
Holes in the roof
Mold or mildew in the attic
Spongy feel when walking on the roof
Granular wear to shingles
Damage around chimneys, pipes, and other penetrations to the structure.
Wet spots on your ceiling
Sudden increase in electric bill

There are some DIY inspections that you as a homeowner can do to find the beginning signs of roof deck damage.

Attic Inspection: Carefully make your way up to your attic and check for any signs of rotting wood. Do you see any signs of staining or moisture on any of the plywood or insulation? Can you feel any dampness in the wood? Is there a musty mold smell lingering? Can you find any holes, possibly made by a new furry neighbor? Is your attic fan and ventilation system free of dust & debris and circulating the air properly?
Ground Check: You can take a trip outside and stand in front of your home to view your roof from the outside. Are there signs of curling or missing shingles? Can you notice any sagging or structural integrity issues with your roof?
Research Roof’s Age: Severe weather or a poor ventilation system can decrease the life expectancy of your roof. If your roof is more than 20 years old, it’s a good idea to reach out for a professional roof inspection.

Roof Deck Corrosion

Roof deck corrosion occurs when using steel for your roof deck construction and has been exposed to water either from a hole created from severe weather or poor roof or insulation installation causing gaps between the roofing and insulation and allowing for water exposure.

WARNING: We do not recommend walking on a damaged metal roof structure. Corroding metal roof decking can cause structural instability which can lead to the roof collapsing if too much weight is put on the structure, leading to injury. Please refrain from having work done on units on your roof if you suspect instability in your roofing structure.

Some visible signs include:

Visible rusting in roof deck
Pieces of roof deck missing or falling from structure
Wet or damp insulation
Holes/leaks in roof

If you believe that your metal roof decking may be damaged, immediately have a professional roofing contractor, e.g. Infinite Roofing, come do a thorough and safe inspection of the roof.

So What Do I Do? Repair or Replace?

Rotted or corroded roof decks, whether made of plywood, steel or any other material, cannot be repaired and must be replaced. Contact your local certified roofing contractors and set up an appointment to have the damaged roof deck to be replaced.

What are “Storm Chasers”?

June 3, 2019 by Infinite Roofing Leave a Comment

Your roof can suffer a great deal or damage when a big storm hits and your roof takes storm damage. Typically, this storm damage is covered by your homeowner’s insurance, which means you are more likely to take action to repair or replace your roof. “Storm Chasers” are fraudulent roofing contractors that know about the increased likelihood of roof repair in areas affected by large storms, and can rip off homeowners with poorly constructed roofing projects. Knowing how to identify these storm chasers can help you avoid falling for their corrupt tactics.

What is a storm chaser?

Roofing contractors who go to areas recently affected by storm damage, rain, hail or strong wind are called storm chasers. They use special programs to locate large storms and determine the value of affected homes. These roofing contractors have immense knowledge about insurance companies they use their knowledge to estimate the cost of a new roof. Local and reputable roofing companies are most likely overwhelmed and overbooked, and the “Storm Chasers” use that to their advantage and go door to door to notify residents that they have roofing services available. Typically, they will start by offering a free roof inspection.

Why are they unreliable?

Most storm chasers only do the bare minimum to replace a damaged roof. They will find the cheapest materials to quickly assemble a new roof, often leaving out important elements that a professional roofing company would take in consideration, and they fail to restore things back to their original condition. The roofs that are installed by them usually only have a lifespan of fewer than 10 years because they are installed using cheap material, whereas a professional roofing company using high-quality materials and techniques would leave you with a roof lasting 40 years with warranties to back up their install. Professional roofing companies have the certifications and licensing while storm chasers usually do not have the proper licensing or insurance to work on roofs.

In some cases, storm chasers do not replace the roof at all. Instead, they give a free inspection, quote a reasonable price and ask for upfront payment. Once they are paid, they move on to the next town without any intention of working on the roof.

What tactics do storm chasers use?

If you want to avoid being scammed by storm chasers do your research before handing over any money. Make sure that the contractors you hire to replace your roof or fix the storm damage have a reliable background and pay close attention to the approach they use. There are a few telltale signs that a contractor is a storm chaser.

1-They come directly to your home

The most obvious tell-tale sign for storm chaser is that they come directly to your door, Roofing companies don’t go out looking for work, especially after a big storm, they know that work would be coming to them as people will try to find reliable roofers in Albany to deal with their insurance agency and get the best repair or replacement possible. Storm chasers, on the other hand, move around to wherever the storms go, they cannot rely on the chances that people in need of roof repair will find them. Sometimes storm chasers go so far as to pretend they were sent by a company that previously worked on your roof. If this happens, ask for proof.

2-They want payment upfront.

No roofing company will ask for payment upfront before starting the job, When you pay storm chasers upfront, even if it is just a deposit, it is likely that it will be the last time you ever see them.

3-They offer to pay for the deductible.

How nice would it be to have your insurance deductible waived? Storm chasers think so, too. If a roofing contractor offers to pay for your deductible, they are probably a storm chaser. It is considered insurance fraud to allow a contractor to pay the deductible. If you let a roofing company pay your deductible, you will be the one responsible for committing the illegal act. Make sure you are familiar with your insurance policy and the laws regarding fraud to prevent yourself from falling into this trap.

4-They create damage that was not there before.

Because they are usually familiar with the insurance claim process, storm chasers sometimes create their own damage if the real damage is not sufficient. They may use golf balls, hammers or other hard, heavy objects to pound dents into your roof. Watch and listen carefully as contractors inspect your roof and have a camera or cell phone ready to catch them in the act if you are suspicious. Adding fake damage for the purpose of collecting insurance money can have serious consequences.

Educate yourself and your neighbors about the common signs of storm chasers to avoid being the victim of a roofing scheme. Check the Better Business Bureau if you are unsure of the legitimacy of a roofing contractor. This will tell you if the business is local and if complaints have been filed against it.

Infinite Roofing and Construction is proud to boast an A+ rating on the BBB. We are a local, trusted roofing company in Albany with over 20 years of experience. Getting a new roof is an expensive endeavor, so make sure you are getting it done right the first time by a company you can trust.

Do you really need 3 estimates for a roofing job?

May 29, 2019 by Infinite Roofing Leave a Comment

You’ll need to get as much information and knowledge about the process when looking to replace your roof. You need to weigh your options for roofing materials, their cost, and learn as much as you can about the local roofing companies that will be doing the work. In particular, your goal should be to find the best work for the best value.

Conventional wisdom, and also your insurance companies state and push that you should get three estimates from your local roofing companies and choose the median. Why? Supposedly, a drastically lower estimate may indicate cost-cutting measures that could result in shoddy workmanship, while the highest estimate could wind up costing you a pretty penny for average durability.

Meanwhile, if you’re replacing your roof due to an insurance claim, your insurance company may be stressing that you obtain at least three estimates. However, the three-estimate rule is not a hard-and-fast requirement for insurance claims, nor is it a necessity for your own decision-making process

So how many estimates do you really need?

The thought process behind requesting multiple estimates is solid. replacing a roof is a major undertaking that costs you a good deal of money and stands to make a lasting effect on your home’s weatherproofing, durability, and resale value for years to come. Of course, you want as much information as possible so you can feel comfortable proceeding. You also want to make sure the local roofing contractor you choose provides high-quality materials and high-quality installation and the best way to make that determination is to compare them to other local roofing companies that offer the same service.

However, do you really need three estimates? Not really. In this case, the “right” number of estimates depends completely on you. Get as many, or as few estimates as you need in order to feel comfortable with the roofing company you choose and their pricing.

Insurance companies are in no way required to get three estimates. All roofing contractors receive payment following a third-party system designed to set industry standard prices. Your insurance company will pay your area’s best roofers in Albany the exact same amount as it pays the worst roofers in Albany. Gather as many estimates as you feel comfortable with and choose the best company, just as you would if you were footing the bill on your own.

How do you go about choosing the best company? Ask these questions aside from the affordability factor to determine the best roofer in albany for your job.

Have they performed work in the area? Ask for references and addresses. There’s no better way to get a feel for a company’s customer service and workmanship than by speaking with former customers.

How experienced is the crew? It’s a good sign if your roofing company has been in business for decades and has great reviews. However, make sure to ask about the experience level of the particular crew that will be performing your work; a long-lasting company can easily hire a crop of newbies that may not have any more experience than you do.

How can I reach out during the process? Asking this question, in particular, gauges the company’s customer service. Their willingness to answer questions, guide you through the process, and remain available speaks to how smoothly the process will go on install day.

Ask about any certifications that the roofing company may have, having certifications backs up the work that is done by the company and it would guarantee that they have the best training necessary to be working on your roof.

There is no number of “right” estimates that you would need to get, go with what you think is suitable for you. Infinite Roofing can provide you with a free estimate for your insurance company with a detailed inspection of your roof. Our certifications, reviews and our highly trained crew will guarantee a happy and easy going roof installation.

The top 5 Roofing Problems to ‘Keep an Eye Out’ For

October 26, 2018 by Infinite Roofing Leave a Comment

At some point, every homeowner is going to run into a problem with their roof. It may be from a storm causing damage, an improperly installed roof or from one that just got plain ole’ old. Problems can range from tiny leaks all the way up to catastrophic cracks and punctures.

Here are the most common problems to keep an eye out for:

Drip, Drip, Drip: Leaky Roof

leaking roof — Hopefully your roof leak isn’t this bad.

The single biggest problem that leads to a phone call from a homeowner is going to be because of a roof leak. Much of the time, a leak is caused by either improperly installed or cracked flashing. The flashing on your roof is the metal parts that border things like chimneys and sections of the roof where it meets siding.

Flashing is supposed to reinforce the seam between the shingled area of a roof and a “non-roof” section and create a waterproof seal at these classically vulnerable spot.

Other common causes of roof leaks are broken tiles, slate or shingles.

When a roof leak happens, the vast majority of the time it’s going to come from areas around gutters, at skylights, near the chimney and close to vents or piping. Any area that has flashing is a potential leak source as well, in addition to areas around damaged shingles and in valleys (where two sections of roof meet).

Here’s the tricky part about roof leaks: they’re not always caused by obvious drops hitting the floor. Most of the time, an initial leak is going to get absorbed into the wood that makes up rafters and walls.

So if you’re looking for evidence of leaks, check for water damage on drywall and in the rafters first.

Ponding Water on the Roof

Ponding water is when water stands still in one spot and does not properly drain off the roof as intended. These pools eventually cause the integrity of the roof to deteriorate and become corroded and can cause a bunch of issues from leaks to premature failure.

These are a particular problem when it comes to flat roofs, which aren’t always as well equipped to handle drainage as a pitched roof is.

Clogged Gutters Causing Moisture Damage to the Roofing System

You may not think gutters have anything to do with the roof – but one of the leading causes of roof failure is a clogged gutter system.

See what happens is, when your gutters get clogged up (especially in the fall), it prevents water from draining properly and inevitably you have water build up, which backs up into the roof area (which is designed to quickly drain water off of it to prevent standing water damage).

When water sits and stands and sloshes around the roof, which is not designed to hold water for long periods of time, it causes the eaves to eventually rot, which then causes the roof’s integrity to fail, leading to more drainage problems.
This problem is what’s called a “failure cascade.” You do not want a failure cascade. Failure cascade means an easy-to-fix problem turns enormously expensive.

Fortunately, this problem is easy to fix by simply making sure your gutters are regularly cleaned out (either you yourself doing it, or having professionals regularly clean them out) and/or by having properly installed gutter guards that just prevents the biggest causes of gutter clogs from ever happening (like those massive oak leaves getting in there).

Snow and Ice Damage on the Roof (e.g. Ice Dams)

Snow and ice causes continual damage to any roof, making it a particular problem here around Albany and Saratoga. They cause havoc because snow eventually melts into water, then seeps underneath the asphalt shingles. If this water happens to refreeze, then you’ve got shingles that start popping off and ruining the integrity of the roofing system altogether.

This melting and refreezing can even get up underneath flashing – causing a “lifting” effect that pretty much permanently damages the material, which then lets even more melt water into the area, eventually leading to leaks and moisture damage.

There’s really only one way to stay on top of this problem: regularly inspect your roof in the spring and fall and catch minor problems as they occur, preventing any catastrophic repair problems and elongating the roof’s lifespan.

Poor Installation by a Roofing Contractor

This problem can’t be understated enough – and is one of the top reasons why hiring a roofer is almost always better than hiring a general contractor. Roofing requires a very specific kind of expertise and an eye trained to pick up on the small details of each unique roof. Additionally, you’re going to want to make sure that any roofing company or roofing contractor you hire is properly certified by the shingle manufacturers they’re installing.

You can tell when a poor installation happens by looking at the flashing or how even the shingles are. If the shingles aren’t leveled and they aren’t in a straight line, then the roof installation wasn’t done right – and that’ll cause drainage problems and premature leaking.

The biggest indication comes when you’re looking at the flashing around areas that connect to siding or chimneys or pipes. When flashing is properly secured or is not properly installed against the siding, what ends up happening is it does nothing to prevent water from getting into the plywood or wood areas that make up the connection points on your roof.

When the flashing is improperly installed like that, it’s really no better than just having exposed plywood out there absorbing all the water everytime it rains. The wood underneath then rots out, leading to a mold and mildew problem, termites and other devastating issues that just completely rot out the infrastructure and integrity of your home, leading to a hugely more expensive problem.

A shoddy installation isn’t just bad because your roof ends up leaking – it’s bad because oftentimes it’s going to cost up to twice as much to simply remove the old roofing, which will inevitably expose more problems that were unknown that must be fixed that leads to more expense and more materials, with the alternative being “well, just roof over it and have to deal with the problem every 3-4 years (which is an option you should never take).
