5 Reasons to Replace Your Skylight

5 Reasons to Replace Your Skylight

money.jpg

 1. Save Money

Replacing your skylights when you replace your roofing system is the most convenient and affordable time to do so. Most roofers will charge up to double to come back and replace your skylights separate from replacing your roof.

2. The Risk vs. Reward

If you really want to save money on your roofing purchase, think long-term. A slightly larger investment of a new roof and new skylights now will cost less than ripping up your new roof to replace old skylights in the future.

 3. Seal Failure

What happens if you replace your entire roof and don’t replace the skylights and 6 months down the road, you have seal failure (fogged, inefficient glass)? You guessed it; you have to replace that entire section of shingles around the skylight! All of the banging, tearing off, dumpster in the driveway, permitting, scrapping, nailing, mess in your attic, and living in a construction zone will all have to happen again.

4. Using old skylights with a new roof can cause leaks

Say your skylight has performed perfectly in the years leading up to your roof replacement. No matter how skilled your contractor may be, ruffling with that old skylight can cause problems. And keeping skylights in place only to have them leak afterwards isn’t worth the trouble, especially if disturbing the skylight itself can lead to leaks.

Building materials expand and contract over time and what many homeowners don’t understand is that you must partially disassemble the skylight to re-flash the skylight. This process can create many problems in the structure of the skylights if they have started to corrode.

5. The skylight will have to be replaced eventually anyway

Skylights have a short warranty for a reason. Inexpensive plexiglass bubble skylights can crack easily. Even high-quality skylights will warp over time. Choosing to re-flash rather than replace can result not only in leaks and moisture buildup, but also in expensive energy loss. Technology has advanced in the past 10 years and Velux, a brand we trust, has an advanced Low E-3 coating that provides more daylight and better heat control than older plastic models.

The most convenient and affordable time to replace a skylight is when you are installing a new roof.

By replacing your skylights when you replace your roof, you’ll save money in the long run and ensure you won’t be paying for a new roof twice! You can also take advantage of the new energy efficient models (there are solar powered options!) and increase the thermal comfort of your home with natural ventilation.

Flat Roof Options

Flat Roof Options

TRADITIONAL SYSTEMS

The first type under this category is built-up roofing, one of the oldest and most reliable types of roofs. It consists of several plies of roof felt laminated in hot asphalt. It’s surfaced with gravel set in a flood coat of asphalt. Modified roofing, on the other hand, usually has two plies of roof felt laminated in warm asphalt but with a cap sheet covered in ceramic granules.


SINGLE-PLY SYSTEMS

The EPDM is one of the most common types of flat roofing materials, thanks to its affordability and ease of installation. It is also odor-free, unlike built-up roofing systems. EPDM roofs can be fully adhered, mechanically fastened, and loose-laid. Other types of the single-ply systems include TPO and PVC.


COATING SYSTEMS

Lastly, there is a complete product lineup of coating systems that can be applied to any type of existing roof surface. The coats form an impermeable membrane over the roof’s surface. They also have a reflective white surface that can help save energy.

Choosing A Shingle Color

Choosing A Shingle Color

Choosing The Right Color For Your Roof Replacement

A roof replacement is one of the best ways to add style and value to your property. Before you start building your new roof, however, you will need to choose which roofing materials and colors will be the best fit for your home. With services from a company that specializes in roofing near Lancaster, you will be able to choose between roofing products that come in an assortment of colors and styles. If you are planning on replacing your roof, read these tips for choosing the right color for your design.


Examine Your Paint Colors

Your home's exterior paint will have a major impact on the look of your new roofing installation. To choose the best color for your new roof, be sure to carefully consider which roofing colors will compliment your homes current paint color. If your home is painted in a light shade, you may want to pick out a softer roof hue. Dark homes look best when they are paired with equally bold roof color choices.


Compare Under Various Lighting

Throughout the course of a single day, your roof may be in direct sunlight and total shadow. If you want to make sure that you are pleased with the color of your roof, no matter the lighting situation, compare your roofing shingle samples under various lighting conditions. A shingle color that looks great in full sun and complete shade will be a great condition to your home.


Choose a Single Color

There are several schools of thought when it comes to mixing and matching colors in your roofing shingles. While multicolored shingles can provide your roof with visual appeal, having too many different colors on your roof can make your home appear busy or cluttered. When you are in doubt about your color options, stick to a single shade for your shingles. By picking out one complimentary color, you can rest assured that your new roof is both stylish and functional.

Consider a Metal Roof

Consider a Metal Roof

Why Is Metal Roofing Good for Homes?

When most people think of metal roofing, they think of commercial buildings. However, it also offers many advantages for homeowners. Greenawalt Roofing has several reasons why you should consider installing metal roofing at your home.

  • It’s long-lasting – While they may be more expensive than other types of materials for residential roofing, the payoff is worth it. Metal roofing requires hardly any major upkeep and can last up to 50 years. You’ll hardly ever have to worry about calling for a roof repair.
  • It reduces heat – Metal roofing reflects the suns harsh rays, keeping your home cooler. This will help you reduce your energy bill during the warmer months.
  • It’s fireproof – When it comes to protecting your home from fire, a metal roof can’t be beat. The metal material is resistant to fire and can keep your home safe from blowing embers.
  • Ignore these myths – Metal roofs do not make more noise or attract lightning any more than other types of residential roofs. If you’re still concerned about sound, install another layer of insulation in your attic to reduce possible noise. Install lightning rods or other equipment to protect your home from possible strikes.

Great Color Schemes for Your Home

We suggest three excellent color schemes to try below.

Yellow – White – Reddish Brown

tudor.jpg

This color scheme is inspired by the subtle brown tones on Tudor style homes, but remains versatile with the addition of a bright yellow. Bold hues are best for contemporary homes, while more subtle shades in the same color family would work well in traditional homes. To keep this palette from being too overwhelming, we recommend choosing a neutrally stained wood door and white accents.

Gray – White – Black

grey.jpg

Modern homes can sometimes feel a bit uninviting with their sleek lines and minimalist design. To achieve a warm yet still contemporary vibe, invest in vinyl siding in a light gray shade and use lighter tones to highlight your homes architectural details. White is a great accent color for this aesthetic because they can be both warm and cold depending on the saturation, making them a flexible option.

Peach – Light Brown – Brown

victorian.jpg

Many traditional homes, like Victorian homes, showcase a myriad of colors in their exterior color palettes. If you’re not a fan of this, you can keep things soothing and simple with warm shades. Use peach, the lightest shade, for the majority of your home, like the siding, and complement it with red-tinted browns and cream.

Greenawalt Roofing Company can provide a professional siding installation for your home.

Summer Roof Maintenance Tips

Summer Roof Maintenance Tips

Gutters and Downspouts

gutters and downspouts.jpg

Clogged gutters and downspouts can add moisture around the eaves of your house, which will eventually cause water infiltration into the roof if not corrected. You can check to see if they are flowing freely on a rainy day but it is best to inspect them visually.


Look for Leaks and Signs of Mold

roof_leaks.jpg

Did you know that mold on a ceiling can indicate a roof leak? You can also find indications of a leak by inspecting the underside of the roof in your attic. Unfortunately, mold can manifest itself in your attic from a roof leak or from improper ventilation, so make sure the problem is taken care of quickly!


Check for Proper Ventilation

The Roof Medics - Vent Turbine.jpg

An attic without proper ventilation can become overheated in the summer or build up condensation in the winter. This moisture can produce mold and mildew -- and an overheated attic space can increase power bills. If your home is over ten years old, chances are your attic is not properly ventilated.


Check the Flashing

flashing-roof-wall-intersections-2.jpg

Flashing is used in the valleys of your roof to direct water away. Flashing is usually made from aluminum, plastic, or a composite material, flashing needs to be properly sealed to prevent water infiltration into your home. If you need help weatherproofing your roof, it may be a good idea to get in touch with the professionals.


Check the Pipe Boots

content_00_a95d11_1140x735.jpg

Placed around any vent pipes that extend through your roof, pipe boots are the number one cause of most roof leaks. Made from plastic, they tend to break down due to exposure to the sun and you need to make sure they don't need to be replaced -- and if they do, enlist the help of a roofing expert like Greenawalt Roofing.

Bird Damage

Bird Damage

Nest2.JPG

Birds can cause considerable damage to virtually all types of roofing. Their droppings are extremely acidic and tend to eat away at roofing materials, particularly at any tar-based system, like asphalt shingles. Studies have shown that the life expectancy of a warehouse roof can be cut in half just by the continuous application of bird droppings. Bird droppings can also have a deleterious effect on air conditioning equipment.

There are other dangers to watch for with our feathered friends. Bird nests are often built in gutters and drains. When the drainage system is blocked, the continual application of standing water to roofing materials can cause serious damage. In addition, blocked gutters often overflow and cause water to penetrate the substrate or the roof of even the walls.

Yet another danger with birds’ nests is from fire. Because the nesting material is highly flammable — since it is made of up dried twigs, grasses and other natural items — when tucked next to electrical machinery or electric signs on a roof, the bird’s nest can quickly catch fire.  Finally, birds often build nests in chimneys and in ventilation systems. Blocking the air flow in a chimney can have terrible consequences with smoke backing up into the building. In addition, blocked attic vents don’t allow the roof to breathe properly. Bird nests and their droppings, particularly pigeons carry many diseases, which can easily be spread to the interior of the building through the ventilation.

Buying a Home?

Buying a Home?

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.

new-home-1540871_960_720.jpg

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.

IMG_3654.jpg

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.

black-streaks-on-roof-shingles.jpg

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.
