Roof Inspection is Critical!

Next to the cost of the home itself, nothing will cost you more than having to replace the roof. That's why it is critical to get a roof inspection prior to buying a home. The roof may appear fine from the ground, but only an inspection can show hidden issues, like improper venting, poorly installed gutters, hidden mold and mildew, dry rot and other defects. Getting a professional roof inspection will cost you far less than a roof replacement.

Here is a checklist of items based on the most common roof problems that you can ask your roof inspectors to look at for you:

  • loose, broken or missing roofing material (like shingles, tiles or shakes)
  • blistered, curled or split roof shingles, shakes or tiles; watch for dark patches
  • large amounts of granules in the rain gutters — granular coatings on asphalt shingles wear away and the shingle looses integrity and its protection capabilities
  • improper installation of air conditioning or vents
  • sagging in the ridges or in the center of the roof or sagging decking between the rafters
  • loose, missing or corroded flashing - particularly near perforations in the roof like plumbing vents, heating or cooling vents, chimneys and skylights
  • broken or loose shingles at ridge lines and hip lines
  • rusty metal or loose shingles where vertical sides of the house meet the roof
  • proper ventilation to make sure your roof can breathe
  • blisters, depressions near vent pipes, clogged drains on flat roofs, separations in flashing
  • overflowing gutters or excess water pooling near the foundation of the house
  • signs of leaking in the attic area — dark spots in the wood (especially around chimneys, vents and other holes to the roof)
  • wet or soft dark spots mean they are a current problem, dry and hard dark spots indicate an old problem that has been fixed
  • signs of leaking or water damage - water stains or sagging ceilings

If the roof inspector finds damage, have them write up an estimate on the cost. Then you can take the list of damage and estimate to the seller and negotiate the price or insist on replacement before purchasing the home.

Dark Stains & Streaks

Dark Stains & Streaks

Have you noticed dark streaks on your asphalt shingle roof? If so, you aren’t alone. Many houses across much of middle and eastern America and the western coastline develop these stains. However, this discoloration can appear almost anywhere.


The dark stains may come from a number of sources. This includes dirt, mold, mildew, and imperfections in the shingles themselves. However, these streaks are most commonly caused by Gloeocapsa Magma, an algae that feeds off of the limestone in the asphalt tiles. This algae is spread by airborne spores.

Are these dark streaks harmful or just an eyesore?

20150609_161822-black-mold-on-roof-large.jpg

The algal stains caused by Gloeocapsa Magma are, in and of themselves, not harmful. However, the consistently humid conditions that allow the algae to thrive may eventually become a problem. What if your asphalt roofing tiles are improperly installed or very old and overdue for replacement? Moisture may creep into the gaps and cracks around them, potentially damage your roofs structure, and even create a breeding ground for mold in your house itself.

Even if the staining doesn’t hint at a deeper problem, the roof's appearance may affect how well homeowners enjoy their property. A streaked roof creates an eyesore that clashes with otherwise neat and well-kept home exteriors and landscaping. It could also put off buyers when the property is put up for sale by implying the owner isn’t passionate about maintaining their home.


What can a homeowner do?

The first line of defense against these dark stains is prevention. Homeowners can invest in algae-resistant roofing shingles. These may appear to be regular tiles but have small amounts of copper mixed in to the coating. Copper is naturally toxic to Gloeocapsa Magma and will deter the algal growths that cause dark streaks.

It’s also important to have the roof properly installed by an experienced professional such as Greenawalt Roofing Company to ensure the longevity of your shingles and create a good seal against moisture.

If you already have stains on your roof, there are a number of products on the market that can remove them. For mild staining, a simple oxygen bleach solution can do the trick. This is also relatively gentle on the asphalt shingles and not very harmful to the environment. For severe staining, you may need harsher chemicals or pressure washing. These are effective on extensive or dramatically dark stains, but may decrease the life of your roofing shingles.

Is this a good project for a handyman or DIY homeowner? Probably not. The treatments that are least likely to damage the roof are also least likely to have any effect. It may be best to call a professional who will get the job done right the first time around.

Sun Damage

Sun Damage

4 Ways to Tell if Your Roof is Sun Damaged

The sun can take its toll on the exterior of your home, especially your roof. If there isn’t much tree coverage around your home, there is a real possibility that your roof can be showing signs of sun damage. This is especially the case if your roof is older, and it has spent many summers under the glaring sun.

1. Your Shingles are Warping

Are your shingles curling upwards? If so, this may be a telltale sign of warping. Shingles that curl and bend up may have been subject to intense heat or sun. If your shingles are old, there is a higher chance the the sun will result in warping. Unfortunately, the warping will only get worse over time as it’s exposed to more sunlight.

2. Your Shingles are Decaying

Shingle decay is possibly one of the worst after effects of sun damage to your roof. When your shingles are exposed to the suns rays year after year, your shingles may begin to decay. This is also more common in old shingles, and newer shingle technology provides more resistance to harmful UV rays. The bad news is that once a few shingles begin to decay, the rest will eventually follow suit. This can lead to a number of issues if the problem isn’t addressed.

3. Faded Shingles

The shingles on your roof not only provide protection, but they also can transform the look of your home. However, the suns rays can result in roof discoloration overtime. The sun essentially bleaches out the color from your shingles, but the good news is that discoloration is only an aesthetic problem—which means that homeowners won’t experience any performance issue from faded shingles.

4. Water Leaks and Damage

The worst scenario that results from sun damage is water leaks and water damage. If your shingles warp, crack, or decay from the heat, this can allow moisture to get into your home. Eventually, the moisture will result in water damage and even mold.

What is Drip Edge?

What is Drip Edge?

Drip edge is a metal flashing that is installed at the edges of the roof to help control the flow of water away from the fascia and to protect the underlying roofing components. Drip edge overhangs the sides of the roof and has a small metal flange that is bent away from the fascia. It is non-corrosive and non-staining so that your roof looks good but is structurally stable.

Reasons to Use Drip Edge:

  1. Directs water away from the fascia and prevents water from rotting the fascia over time.
  2. Protects the edge of the decking due to water penetration during driving rains.
  3. Seals any gaps at the bottom of the roof -- where there is often a gap between the decking and the fascia -- which could allow small animals to enter the attic.
  4. Helps protect the bottom of the roof line during ice dams that can occur during the winter months.
  5. Prevents movement between fascia and deck boards.
  6. Assists gutters to direct water away from your house and foundation.
  7. Extends the longevity of your roof and improves its overall effectiveness.

Nature of Roofing

Nature of Roofing

Since the beginning of time, humans have been looking for way to keep the rain off our heads. We’ve used a multitude of materials, with relative success. Until about 5,000 years ago, primitive man used sod, grass, sticks, wood and animal skins — whatever was handy from the environment — to keep the rain off. Then the ancient Egyptians and other bronze age societies discovered how to roof with plaster and even stone. Today, with our advanced abilities is chemical preparation and petroleum derivatives, we have asphalt shingles, modified bitumen, single-ply, foam… well you name it.

And yet, no matter how advanced we become, Mother Nature always has surprises for us. Global warming seems to be throwing our storms into high gear. For example, during the first quarter of 2018, the East Coast had not one, but three 500-year Nor’easters. Seems like the nasty storms are coming more frequently. In short, the weather brings all kinds of challenges, all designed to remove the roofs from our heads.

  • A quarter inch hailstone can crash into a roof at 20+ mph. That’s not lethal, but it does a good job of damaging roofing materials.
  • One molecule of water is so small it can slip into almost any space. When it freezes, it expands, making the space around it larger. The process of freezing and thawing act like a wedge, making larger and larger spaces where more water can invade. The process is extremely hard on roofing materials.
  • The combination of heat and water also promotes all kinds of microbial growth. The tiny rootlets of these microbes and plants dig into the roofing material, slowly degrading it over time.
  • When water turns to snow in colder climates, it adds a whole new set of challenges for roofers — they have to build roofs to withstand snow load, as well as to prevent ice dams.
  • Sunlight has two byproducts, heat and UV radiation. UV radiation chemically breaks down all the nifty petroleum and polymers we’ve created. Heat causes trapped moisture to evaporate and turn to gas. If that gas happens to be between layers of your roofing material, it is likely to blow holes through the material to escape.
  • Last but not least is the wind factor. Wind flowing across the surface of the roof increases internal air pressure, which in turn increases the uplift on the roof. When wind speed doubles, pressure quadruples. In short, the wind is just dying to tear your roof to shreds.

The roofing industry is trying to combat all these factors with new technology.

  • Fibers are being mixed into the polymers and petroleum products to help resist impact damage.
  • New coatings are being developed to help bounce debris off the roof without damaging the materials.
  • Other coatings are being used to reflect heat, UV radiation, resist fire and more.
  • Additives are being mixed into the polymers to improve tear strength, UV resistance, flexibility, fire resistance and dimensional stability.
  • Improvements to the bonding agents and waterproofing materials are helping to keep the moisture out of the roofing layers.
  • Improvements in flashing, fasteners, water drainage systems and more are all coming together to make roofs less susceptible to water penetration.

So many new things are happening that you may have a hard time keeping up with all the improvements. We’d be happy to consult with you to help you select the proper materials to help your roof last as long as possible.

About Roof Pitch

About Roof Pitch

So what is roof pitch?

Roof pitch is the vertical rise of your roof divided by the horizontal span (or run).  It is typically expressed with the rise first and run second, with the run denominated by the number 12, giving a ratio of how many inches of incline there is to each foot of run. For example, 3:12, 4:12, 5:12, and so on.

Don’t worry, here it is in simple terms. Roof pitch is the slant or steepness of your roof. You might have a very steep slant with high peaks or no slant at all (flat). The term flat roof is misleading however, since even a flat roof is not truly flat. It should have a 1 to 2% minimum slope so that water runs off.

And that is the primary purpose of pitching a roof — to redirect water and snow so it won’t pond on your roof and cause serious damage to your roofing materials or even catastrophic collapse. Typically, areas with higher rain or snowfall have a steeper pitch — some of the roofs on eastern seaboard just didn’t have enough pitch to withstand the heavy snowfall, or worse yet, they were built correctly but the roofs weren’t well maintained.

Every state and community has regulations and requirements for the pitch of a roof. It is a good idea to check with a professional roofer or building official to learn what those regulations are before picking out a building or home design that might not work in your area.

Your Roofing Dictionary

Your Roofing Dictionary

We understand that not everything we say in the roofing industry makes complete sense. Everyday words may have a completely different meaning in the roofing business, and to the untrained ear, it may even sound like we're speaking gibberish. As a home owner though, you should be "in" on our roofing lingo, so you're fully aware of your roofs needs. That's where our roofing dictionary comes into hand.

Asphalt Plastic Cement

Often referred to as mastic, blackjack, roof tar or bull, this asphalt-based sealant helps waterproof and adhere roofing materials to your home.

Hip Roof

We're not talking about how cool your home is when we refer to your "hip roof". Instead, we're referring to your roofs angles. A hip roof has four planes that slope downward from a single peak.

Flashing

Flashing is a material used on a roof to transition from roofing to something that is not your roof. Typically used around chimneys, metal, tin, copper, plastic, or lead flashing is a small installation that plays a huge part in water and weather-proofing your home.

Blistering

Blisters on humans are usually a result of a burn or friction. Blisters on a roof are the complete opposite. In roofing, blisters refer to the bubbling up of shingles, usually caused by excess moisture in either the material itself or underneath the material.

Telegraphing

Unfortunately, if your roof is "telegraphing", it's exactly what it sounds like. Your shingles, similar to the look of Morse code, are reflecting the bumps, unevenness, and sometimes buckling beneath their surface.

Crickets

No, we're not installing small, chirping creatures to your rooftop. Roof crickets, or saddles, are ridge-like diverters that we install behind the high side of a chimney, or other roof projection, to keep water from pooling in the crevice.

Over Driven

When we say your roof is over driven, it means that too much force was used when fastening your roofing materials, and your materials are either breaking or about to break.

Filing an Insurance Claim

Tips for Filing a Roof

Replacement Insurance Claim

Sometimes it’s an unexpected disaster, a bad storm that takes a toll on your roof. Sometimes it’s something you’ve seen coming for years. But when it comes time to have a roof replacement, you know you can’t avoid it for long. It’s a stressful situation in general, but one of the most stressful aspects of the process is trying to file an insurance claim for the roof replacement. The long phone calls, the follow-ups, sometimes even the involvement of your mortgage company, can all combine to form a beast of a headache for homeowners. In these cases, it can only help to be prepared. Here are some steps you can take to make the process a little easier.


Find Out What Your Insurance Covers

Don’t take it for granted that your insurance policy will cover whatever happens to your roof. Not all insurance policies are created equal. The age of your roof and the reason for the roof replacement all play into how much the insurance company will cover for your roof replacement, or even if they cover anything at all. Your policy can also change from year to year, which can make it difficult to keep up with what it covers. When it’s time for a roof replacement, you need to file as quickly as possible to ensure the best coverage, so this is the kind of information you should have before disaster strikes. Call your insurance company to make sure you know what policy you have and keep a current copy of your policy at all times.


Take Full Inventory and Pictures of Damage

When it comes to insurance companies, it’s critical to have a record of all the damage. The day after a storm, you should take a good look at the roof and the attic to list all the damage. Take pictures of everything you see. It’s actually a good idea to take the occasional picture of your roof before it’s damaged, too, so that you have something to compare it to. In this case, it might be a good idea to hire a roofing contractor to do a thorough roof inspection. They may be able to notice damage that you overlooked and point it out to you. They may also have insights on what to expect when contacting the insurance company.


Hire Trusted, Experienced Roofing Contractors

It’s a good practice in any service to hire an expert. The right roofing company, with years of experience and satisfied reviews from customers, will not only be able to complete the work easily–since they do it every day–but they’ll provide a quality roof replacement that will last for years and years to come. But hiring a trusted roofing contractor isn’t just a good idea for the quality of your roofing project. It’s also helpful to find a company that has a great reputation with insurance companies. They can help you through the insurance claim, and when all parties work well together, the entire process will run more smoothly. When you know you can trust your roofing contractors with every aspect of the process, it will be much easier for you to relax through this stressful time.


Greenawalt Roofing not only has years of experience providing quality roof replacements to very satisfied customers, they also have a great reputation with insurance companies. We can work directly with the insurance company to make sure your roof replacement is covered and your coverage is maximized.
