It’s not always possible to prevent damage to your roof or leaks but knowing the shape that your roof is in before a storm or inclement weather hits is the best way to avoid needed emergency repairs. Take a look at your roof from the ground every once in awhile to look for signs of wear such as discolored, loose, cracked or missing shingles. Greenawalt Roofing Company is happy to assess the condition of your roof and whether it is providing the proper protection to your home. 




A common cause of leaks is improperly sealed flashing. When not fastened adequately, the roofing membrane is left exposed and this can allow moisture to penetrate into the attic, where it can run along the rafters and pool in unknown locations. A buildup of moisture is conducive to mold and rot, which can cause structural damage if left unchecked.

It’s also important to store shingles in a proper manner so as to avoid damaging them prior to installation, and we ensure all our shingles are stored in a safe and protected manner, guaranteeing 100% functionality.

When installing single-ply membranes, we pay attention to all seams to ensure total adhesion. Leaks are especially prone to occur along poorly-sealed seams in single ply systems.



Leaks aren’t the only problem that can face a roofing system, and poorly installed flashing can prevent many problems beyond leaks. If the flashing isn’t attached properly, wind may penetrate underneath the shingles and can be strong enough to blow shingles off the roof altogether.  

It’s important to seal all flashing, and to ensure every seam is well-cured before being leaving the job site. Greenawalt Roofing Company takes great care to ensure every facet of our installations & repairs are 100% reliable, thorough, and safe.


Improper Installation

Poor installation or otherwise unsatisfactory workmanship can drastically increase the likelihood of problems occurring, and greatly reduces the expected life of a roof. Taking care to thoroughly clean, dry, and prime an area for installation can go a long way toward ensuring your roof seals out the rain, wind, and snow. Storage and handling of materials is of vital importance for any type of roofing material, and we take pride in our knowledge and ability to handle and store all materials with care.

Lack of Maintenance

Failing to maintain a roof can cause many problems down the road and can be very expensive in the long run. Even if you don’t know a lot about roofing, it’s important to perform inspections regularly. Check for things like ponding water, flashing that isn’t secure, or blistering. Addressing minor problems before they escalate not only saves money but prolongs the expected life of a roof.

Ponding Water

Not only can ponding water add weight, penetrate the underlayment, and foster mold, it can amplify UV radiation and compound damage to the shingles. Check for blocked drains or sagging deck material when assessing the cause of ponding water. It’s important to note the soure of the problem before making hasty repairs, otherwise the problem will inevitably occur again.
