Often it isn’t until your roof begins to leak that you find yourself being grateful for the shelter you once had. So don’t wait until your roof leaks to appreciate it. One of the easiest ways to take care of your roof is to maintain and clean it every year.

Warning Signs Your Roof is in Disrepair

Warning Signs Your Roof is in Disrepair

Many homeowners don’t pay much attention to their roof until there’s an obvious sign of damage. This is a mistake; being able to identify and address roofing problems before they cause widespread damage can save you time and money.

Below is a list of four signs your roof is in need of a full replacement.

1. AGE

A good asphalt shingle roofing system can last up to 30 years. If yours is reaching that point,  it’s smart to ask professionals to inspect your system and provide a status update. An expert can tell you whether it’s safe to squeeze a few more years out of your system or if you need to replace it now.


Curling, cracked, or missing shingles are a very bad sign for your roof. This problem means your underlayment is exposed to the elements, which can lead to leaks. Contact your trusted roofers if you notice this problem.


Water has a way of seeping through even in the tiniest gaps. If you notice holes that allow rain into your home, consider getting professionals to check your roof. This is a serious matter that requires prompt attention.


A sagging roof often indicates a structural issue. There could be a problem with the decking in the attic or the foundation. Failing to address this poses an actual, physical risk to you and your family.

Roof Replacement Estimate

Roof Replacement Estimate

Getting an estimate is an important step in planning your roof replacement project. A proper roof replacement estimate needs to be detailed and thorough so you can make well-informed decisions regarding your project.


Your roof replacement estimate needs to detail the type of roofing material being used, the manufacturer, the color, and the estimated cost of all materials. The estimate also needs to have an approximate timeline for the roof replacement, a warranty for the project, and the payment due dates and accepted methods of payment.

When reviewing estimates from prospective roofers, make sure to ask plenty of questions. A professional roofing company should be able to provide you with all the necessary information about your project. For example, you need to ask about the contractor’s qualifications. Ask if they are licensed, insured, and certified. Cross-reference their qualifications to see if they are accurate. Ask for specific details on payments and payment schedules.

It also helps if you ask the contractor about their business experience. Ask how many years they’ve been in business and ask to see references and examples of previous roof installations. Make sure to ask about the contractor’s safety record and standards as well. Ask about possible roadblocks such as property damage. At this early stage, you need to know who will be responsible for the cost of damage so everyone is on the same page from the get-go.

Dangers of Roof Moisture

Dangers of Roof Moisture

Dangers of Roof Moisture

A buildings rooftop is designed to protect its interior structures from moisture damage, but rain and snow will eventually degrade roofing materials. If moisture leaks on underlying roofing materials, then damage begins to the building gradually in several ways.

Mold Growth and Mildew Odor

When the shingles on a rooftop develop mold growth, property owners will begin to notice a foul mildew odor. Mold is a living organism that will invade underlying materials such as wood and drywall, and the people who are inside the building can experience allergic reactions from the contamination. The symptoms caused by mold allergies include respiratory distress, itchy skin, and watery eyes.

Rafters and Joists


If moisture reaches a rooftop’s rafters and joints, then the materials will begin to swell and crack during the cold winter months. By the time spring arrives, a buildings roof may have separated from the underlying frame. When materials have separated on a roof, rain and snow will enter the building, causing damage to internal materials such as drywall and wooden frames.

Softening and Weakening Roofing Materials

When roofing materials absorb moisture, the items begin to soften and weaken, making it easier for damage to occur from high winds. Dry roofing materials are less likely to blow away in a strong thunderstorm.

Structural Problems

If rainwater and snow melt continue to leak into a buildings roof, then water enters attics and wall spaces, leading to minor or major structural problems to a building. Instead of needing to spend a few hundred dollars on a simple shingles replacement, a property owner may need to spend thousands of dollars to replace an entire rooftop.

Infestations of Insects and Animals


Animals, birds, and insects are attracted to moist environments, and a wet rooftop with small holes is easy for termites, pigeons, and rats to enter. In addition to having significant damage to a building from moisture, there is a good possibility that the invasions of vermin can destroy the structure.

4 Common Causes of Roof Leaks

4 Common Causes of Roof Leaks

A leaking roof causes more trouble than an annoying “drip drop” from your ceiling; it can damage your attic insulation and roof deck and lead to mold and mildew growth and reduced energy efficiency. Roof leaks can be due to several causes, all of which will require the immediate assistance of a professional roofing contractor.

Here are some common roof leak culprits:

1. Loose, Cracked, or Rotting Shingles: If your roof is 20 to 30 years old, you may see signs of aging such as cracking or rotting. In some cases, the shingles may come loose and fall to the ground. A weakened outer layer will expose the underlayment; continued exposure to wind and sun can wear the layers away and eventually cause leaks to form. If your roof is in such a condition, you need to have it inspected. Greenawalt Roofing provides free roof replacement estimates!

2. Roofing Nails Backing Out: Apart from roofing shingles, roofing nails can sometimes back out. This leaves small holes that water can easily penetrate, especially when it’s close to the roof’s edge where wind-driven rain can enter. These little holes are usually unnoticeable to the untrained eye, but not when you have your roof inspected by professional roofers.

3. Damaged or Dislodged Flashing: Flashing is a piece of metal that protects valleys and any spot where the roof meets a vertical surface, such as walls and dormers. If damaged or dislodged by strong winds, this could leave the breaks in the roof exposed, making it easy for rainwater to get in.

4. Cracked Rubber Boots: Plumbing vents and anything that protrudes from the roof require a rubber “boot,” which works like flashing by protecting the area where it meets the roof. Continued exposure to outside conditions will eventually crack the rubber boot, meaning it needs to be replaced.

Is Your Roof Halloween Ready or Just Scary?

Is Your Roof Halloween Ready or Just Scary?

The scariest time of year is right around the corner. Halloween is a moment of tricks and treats, but what about your roof?

If your roof is playing tricks on you with leaks or missing shingles, then give Greenawalt Roofing a call!

As the month of October comes to an end, the fall weather will become very noticeable. Having missing shingles or old shingles can create leaks and cracks in the roof. These are created because there isn’t protection or there is less protection for the plywood and underpinnings. Make sure your home feels inviting to everyone who comes over, even if they’re just ringing the doorbell and leaving after getting some candy.

Maintaining your roof is essential to protecting the rest of your house. Our roofing professionals conduct roof inspections to ensure that your roof isn’t taking on any damage from weather conditions. Simple problems within the roof can lead to some scary problems.

Here are some issues that can take place:

  • LEAKS IN THE CEILING: How does rain leak onto your ceiling? Through the roof. If there are cracks or breaks, even small ones, rain can seep through and cause your ceiling to collapse or suffer water damage. Either way, it would require a replacement of the affected area in your ceiling, along with correcting the issues in the roof.

  • MORE MISSING SHINGLES: Leaving missing shingles on the roof can lead to more missing shingles. When harsh winds hit the gaps in the shingles, it can cause them to be lifted out of place or torn, especially if the shingles are old.


Before Halloween hits, contact us at (717) 898 - 6000. We will provide a full roof replacement estimate free of charge! We look forward to ensuring your roof is ready for the season and for the many seasons to come.

Bird Droppings

Bird Droppings

Bird droppings can damage roofing materials, cause clogs in your gutters, and pose health risks. If you constantly find bird droppings on your vehicles when they are parked in your driveway, you may want to inspect your roofing. There's a high chance that the birds are also dropping their waste on your asphalt-shingled roofing. Here's what you need to know.

Uric Acid in Bird Droppings Damages Roofing

Birds don't produce urine. Instead, they produce uric acid from the excretion of nitrogenous waste. This is the white paste-like goo that you see in splotches on your vehicles. Uric acid can eat away at your asphalt shingles and other roofing materials. Damage to the asphalt shingles can cause them to be more susceptible to leaks. Also, some birds tend to congregate in certain areas, particularly pigeons, which could mean that certain areas of your roof are covered with more bird droppings than others. This, of course, can be detrimental to your roofing and, therefore, to the structure of your home.

Solution: Wash away the bird droppings with a powerful garden hose. Avoid using a power washer as too forceful of a stream of water can further damage asphalt shingles. Hire a roofing contractor to inspect the areas of concern on your roofing..

Seeds in Bird Droppings Clog Gutters

The brown solid substance in bird droppings is poo, which can contain seeds that the birds had ingested. If the seeds are still intact when they are in bird droppings, they can sprout and grow, especially when they reach organic material, such as leaves, or water in your gutters after they wash away from the roofing when it rains. As the seeds sprout and grow inside your gutters, they can cause clogs to form. Clogged gutters can cause water to accumulate and back up into your roofing.

If the temperatures then drop below freezing, this water freezes and can create an ice dam. Ice can get underneath the shingles and cause them to lift up, which can allow more water to infiltrate through the roofing materials. After some time, this can lead to water leaks on the ceilings in your home as the water makes it way down through the roofing structures. You may also notice brown streaks on your siding, which is from water damage of the wood structures in your roofing.

Health Risks of Organisms in Bird Droppings

Bird droppings contain fungus that can pose health risks to you, your family, and your pets. Fungus in bird droppings can be carried in the air and inhaled into your lungs, which can cause histoplasmosis or cryptococcosis, depending on the type of fungus in the bird droppings. Histoplasmosis is an infection by a fungus found in the droppings of birds and bats in humid areas. It is not serious if confined to the lungs but can be fatal if spread throughout the body. Cryptococcosis is an infestation with a yeast-like fungus, resulting in tumors in the lungs and sometimes spreading to the brain. If birds are dropping their excrement onto your exterior HVAC unit, into or near the vents in your attic, or onto roofing that is extensively damaged, there's a risk that the fungus can get into the living quarters of your home.

Quality Gutters

Quality Gutters

Gutters are one of the most often forgotten maintenance areas of a home, yet are one of the most important. Faulty, overflowing gutters can lead to damaged insulation (lower energy efficiency), damaged structural lumber, termite infestations, excessive mold, and unhealthy landscaping. Greenawalt Roofing can replace your damaged gutters and downspouting. Most contractors use high-pressure sprays to clean gutter systems, which can damage your gutters. We inspect all gutters and downspouts and then remove debris by hand and leaf blower to ensure your gutters are left clean but undamaged.

An alternative to gutter cleaning would be to install gutter guards. Gutter guards fit over the entire gutter, allowing water to pass through freely yet preventing debris from clogging the gutters. Contact us today to replace your damaged gutters or to install maintenance free gutter guards!

Halloween Roof Decorating Safety Tips

Halloween Roof Decorating Safety Tips

Planning to decorate your roof this Halloween? If so, you need to be careful about how you approach the project. Roof decorating injuries are common around Halloween and Christmas, and most of them can be avoided with some simple precautions.


Check out these Halloween roof decorating safety tips!

Always Work With A Partner

There should be at least two people involved with a roof decorating project at all times. The second person can act as a spotter on the ground to hold the ladder and watch for potential hazards, or he or she can provide extra support on the roof itself. If an accident does occur, having a second person on site will give you the best chance at getting help as quickly as possible.

Watch For Roof Damage

Discolored roof shingles or areas with missing shingles are accidents waiting to happen. These areas usually have weak substructure from leaking or general wear and tear. Before you walk on your roof, check for any areas that may have damage. Avoid stepping on these parts of the roof. Greenawalt Roofing Company would be more than happy to come out and assess your roof for you during a professional roof inspection.


Inspect Lights And Extension Cords Before Installing Them

Before you put electrical cords or lights on your roofing, make sure they are working and in good condition. Frayed wiring could easily set fire to your roof shingles, or they could damage the rest of your decorations from a shock or short in the wires. Even if you have used the same decorations year after year, you still need to look over them thoroughly before installing them on your roof.

Note: You should ALWAYS use outdoor lighting for your Halloween decorations. Indoor lighting is not designed to withstand the elements and could get damaged in a rain storm.

Protect Plugs From Potential Water Damage

One of the easiest ways to protect plugs for outdoor Halloween lighting is to wrap the intersecting areas with electrical tape. If you are plugging one cord into another, you can use electric tape to cover both parts of the plugs so water cannot get in between. You can always pull the tape off when you put the cords away for the year, but this will keep them safe outside.

Avoid hanging lights in areas where rain is likely to build up, like the edge of your gutters or the valleys in your roofing. You may also have a part of your roof that is more vulnerable to snow build-up than other areas based on how the wind hits it during a snowstorm. If you know of spots like this on your roofing, you should adjust your decorating plans to bypass that.

Use The Right Ladders

Your ladder should be sturdy, secure, and at least three feet taller than the entry point for your roofing. Make sure that there is someone at the base of the ladder to hold it while you climb up onto the roof. Approach the roofing from a damage-free area to ensure that the roof can hold your weight when you reach the top.


Know When You Need Help

If you cannot complete your Halloween roof decorations on your own, don’t risk it. You can hire professionals to decorate your roofing for you because they are sure to have the tools and equipment to get the job done right. Protect yourself and your family by requesting professional help when you need it, and your house is sure to be the talk of the block this Halloween!

Residential VS Commercial

Residential VS Commercial

You may think all roofs are the same, but they actually have different requirements and specifications. Residential and commercial roofing systems in particular have their own specific needs, so it’s important to understand their key differences. This will help guide you in choosing the perfect roofing system for your building.

Here are some of the key differences between residential and commercial roofs:

  • Installation: Depending on the structure’s size, commercial roofs can take weeks to install, while residential roofs typically only take only a few days. Commercial roofs tend to be more costly because they require specialized tools, materials, and safety equipment on site.

  • Slope: Residential roofing systems have steep slopes, which is why they are a key element to curb appeal. The covered areas are also smaller, which means the roof doesn’t put much pressure on the structure. Depending on the materials used, residential roofs are also easier to maintain. Commercial roofs, in contrast, have a slight or flat slope to accommodate structural changes, which means they aren’t visible from the curb. They tend to require more maintenance since they usually cover a larger surface area.

  • Materials: Roof materials for both commercial and residential roofing differ in cost and longevity. They also have their own recommended applications to deliver peak performance. Shingles, tiles, and slate are the most common materials used in residential roofing, as each of these sheds precipitation easily when installed on a steep slope. Commercial roofing usually uses a single-ply membrane or modified bitumen because these materials can cover large areas affordably, while still offering excellent performance.

Choosing a local roofing contractor that specializes in major residential and commercial roofing systems can help you take the right steps and make sound decisions for your property. Greenawalt Roofing can help you with all of your roofing projects.
