Weather & Your Roof

How does weather affect my roof?

Hail damage 497x350.jpg

Heavy thunderstorms and hail can create problems for your roof. After a particular bad storm, make sure to check if your shingles are loose or missing. Another major sign that there is roof damage, is that your shingles are lifted or curling. Also, check your ceiling for any water stains or ceiling warping. Another important thing to check after a storm is the gutter system remains intact and if it is damaged in any way that is room for concern. Just remember when you are checking your home for damage after a storm, do not walk on your roof! It can be weak in spots where it was not before.

If you do spot any of these occurrences in your roof, make sure to call us in order to come do a thorough roof inspection. We will be able to size up the exact damage and tell you how to move forward without, causing any further damage. It is imperative you have your roof checked quickly and thoroughly. Here at Greenawalt Roofing, we pride ourselves on being responsive so that you know your roof is in good hands.


Need a New Roof?

Is it time for your roof to be replaced?

Maybe your siding or gutters?

Here are six questions to ask yourself to help decide.

1. Are your shingles bald, curling, cracked, or missing?

Missing shingles are a telltale sign of a roof in need of replacement. Shingles that are balding, cracking, or curling are likely past their prime. This can signal the damage that the whole roof is experiencing. Without these shingles in perfect condition, they won't function properly, allowing water to get into your home and wreak havoc.

2. How old is your roof?

The age of your roof and the material that your roof is made with plays a major role in deciding if it's time for replacement. If your roof is more than 20 years old, making sure it is thoroughly inspected regularly to prevent leaks, mold, and even collapses.

3. Are there stains and streaks?


Black or greenish streaks on your roof indicate the presence of mold or algae. These growths may cause some damage to your roof on their own, but they're most serious because they're indicative of moisture.

4. Have you had gutter issues or ice dams?

Whether it's built up ice in the winter or leaves in the fall, if your gutters can't drain properly it puts your roof at a serious risk. As the water builds up in the gutters it can be pushed under the shingles and start leaking into the house. Not only does this weaken your roof, but it can create water damage and grow mold.

5. Are there flashing or valley damage?

The flashing around your chimney or a pipe is designed to keep water from getting into the gap between the roof and the item. If there is damage here, it's an easy way for water to get into your home. Similarly, the valleys where water flows to drain off your roof handle the largest volume of rain and snow. If there's damage in these high traffic areas, you're bound to run into issues.

6. Are your walls or siding damaged?

Peeling paint? Moldy siding? Discolored walls? These are all signs of leaks that may be coming from your roof. Damage from storms such as hail can cause gaping holes in your siding as well.

High Wind Damage

High Wind Damage

While many homeowners understand the hazards of storm, hail and tornado damage, few realize that high winds, alone, can cause significant damage to your roof.


Most wind damage that occurs on roofs start on the edge of the roof systems. Wind gusts of 75 to 85 miles have been found to damage shingles or even lift them from rooftops, especially if the shingles are aging or are improperly sealed. Unfortunately, missing shingles can expose your homes roof to costly water damage if they’re not replaced before the next storm comes along.


It is typically changing wind speed and changing wind direction that causes shingles to become dislodged. When this occurs, dirt, leaves, branches and other debris blows underneath the shingles and speeds deterioration of your roofing underlay. Between the underlay damage and the shingles loss, you may need to repair or replace large portions of your roof.


The best way to assess the condition of your roof after any type of storm is to hire a professional roofing contractor to perform a thorough roofing inspection. Greenawalt Roofing is a qualified roofing company that will assess your homes wind damage, determine the condition of your roofing material, and check your gutters to ensure their integrity.

Is Your Roof Ready for Spring?

Is Your Roof Ready for Spring?

As spring approaches, storms and rain can be anticipated.

Here are a few quick tips to ensure your roof is ready to handle this kind of weather:

Have your roof inspected. Identifying and addressing potential leaks before they become problems can save money and prevent headaches. Have all pipe boots and flashings inspected to ensure they are ready to handle heavy rains. Look for loose and damaged shingles, and repair where necessary. Inspect for exposed fasteners, and make sure to apply caulking to the head when you find them.

Clean the roof of all debris. Be confident there are no obstructions to prevent water from freely flowing from your roof and away from your home. Make sure your gutters and downspouts are clean and water is being diverted away from your home once it leaves the downspout.

Be sure to trim any tree branches that may be hanging over the roof. Low hanging tree limbs can drag against your roof and home, damaging its surface. Limbs blown off during storms can potentially cause severe damage to your home. Trimming trees back from your home can help prevent this, or at a minimum, mitigate the damage if limbs do fall on your home.

Got Granules?

Got Granules?


When clearing your eaves troughs, you may notice that some colored granules have accumulated in the gutters. Depending on the age of your roofing shingles and normal weathering processes, this is not unusual. An excessive amount of granules might be cause for concern. But what is considered "excessive"?

Whenever you clean your gutters, always be alert to unusual quantities of granules that may accumulate there and check that your roofing shingles aren't balding.

While there's no way to definitively quantify how much granule loss is too much, the best indication is to look at the roofing shingles themselves. When asphalt shingles are manufactured, more granules are embedded in their surface than are actually necessary so it's only natural that the superfluous, loose granules would wash away first.

Even on brand-new shingles, you can make out the black asphalt the granules are embedded in. However, if the asphalt shingles on your roof have relatively large bare patches where the granules have eroded away and exposed the underlying black weathering asphalt to the elements, you will need to replace any damaged shingles. If the problem isn't limited to just a few shingles, it may well be time for a roof replacement.

Hail Damage?

Hail Damage?


Do you live in one of the highlighted areas on this map??  Than your home's exterior may have been compromised on September 5th, 2017 when a storm came through the west dropping hail ranging in size from .5" to 1.75" on more than 28,000 homes in Lancaster and surrounding areas.

After the storm passed, many individuals were outside taking pictures of the hail that had fallen on their property not realizing that those same pieces of hail may have just caused damage to their roof, siding, or gutters. Hail damage to roof tops often times cannot be seen from the ground, and that is a big reason why the idea of hail damage hardly ever crosses a homeowner's mind. When it comes to your roof, hail spots are not just a cosmetic mark you can ignore. Even the smallest hail impact on a shingle can lead to major problems.

What can hail do to your roof? Once hail hits your asphalt shingles it causes the bond to loosen between the granules and the asphalt layer. When the granules fall off the damaged areas of the shingles, the asphalt layer is then exposed to the elements of the weather. Without a protective layer of granules, the asphalt will be directly exposed to the sun and its ultra violet light will weaken those exposed spots, which can create cracking, blistering, algae formation, edge damage, and water leaks. In the winter, the shingles expand and contract, which can cause curling or cracking on the shingles, which were weakened by hail making them very susceptible to leaks.  

The amount of damage your roof may have faced depends on the type of roofing materials, age of roofing materials, roof slope and quality of construction. It is also important to note hail size, hail density, hail shape and the velocity and angle of its fall as these will determine the amount of damage as well.

When assessing hail damage you can look for some of theses other signs: dented gutters, gutter screens, downspouts,
siding and windowsills/casings or any other signs of impact. If you think you have hail or storm damage - have your roof looked at by a professional right away

Why do you need a professional to look at your roof? First, it is for your safety. With the difficulty of being able to see hail damage to your roof from the ground, an experienced contractor will need to get up on your roof to take a look at the damage. Two, they know what they are looking for. Trained professionals know the differences between normal wear and tear compared to hail damage. Thirdly, they are qualified to work directly with your insurance company to find the best options to get your roof back in shape. Know who is on your roof. To receive the quality of work you deserve, you should always make sure your the crew on your roof is fully licensed and insured and has employees completing the work rather than subcontracting it out to a third party.

Why is it important to file an insurance claim? Most importantly for your benefit, you could qualify for a brand new roof. However, make sure you know your policy because most claims must be filed within a year. By filing a claim through your insurance company you should not have to pay the majority of your replacements out of pocket. Roof storm damage professionals can help you get everything you are entitled to.
