This week JWE Remodeling & Roofing received a phone call from a homeowner in Carlisle, PA 17015 with an urgent inquiry about our south-central PA roofing services. Turns out they had a leaking roof that was getting worse and worse and needed to be repaired. It's a familiar call, so on this page we'll describe the roof repair process and what you can do to prevent or fix your Pennsylvania roof from leaking.

We were able to get out to Carlisle within a day of this homeowner's call. After a thorough roof inspection we were able to trace the two water stains on the home's interior ceilings to their source, and the culprits were two usual suspects: poor chimney flashing and an old unsealed pipe vent.

The story of this Carlisle, PA roof repair is a cautionary tale for all Pennsylvania homeowners who's roofs are more than 10-15 years old. Read about how we identified the leaks and what we did to fix them, so that you can decide if it's time to take a look at your roof and do some preventative maintenance to avoid seriously costly home damage.

Inadequate Chimney Flashing & Old Damaged Vent Pipe

Dry-rot in the rubber gasket on the boot of this pipe vent caused a leak in the roof of this Carlisle PA home.
The pipe vent on this Carlisle roof was old and damaged with dry rot and in need of repair.

Over the course of many years, after being pounded by wind and rain and sun and snow, rubber cracks and seals break. Flashing and flanges installed around pipe vents and chimneys begin to fail. Even roofs that have properly installed components like flashing and vent pipe boots need to be replaced at some point.

This particular Carlisle, Pennsylvania roof could have been sealed better:

  • The chimney flashing was only wrapped around the exterior of the chimney and did not have an adequate seal.
  • There was no counter-flashing or step-flashing installed around the chimney.
  • The caulk that was meant to stop water from leaking between the brick and the metal flashing was old and cracked, which caused a leak inside this homeowner's living room.
  • The pipe vent was not properly installed. Heavy wind and rain was able to drive moisture beneath the flange and under the roof.
  • The roof shingles should have been laid completely around and on top of the metal flange of the pipe vent boot to stop water leaks.
  • Making matters worse, the entire setup was at least 20 years old and (as shown in the picture) the rubber gasket was cracked. Water was able to make its way between the gasket and the pipe and it ran down onto an interior ceiling, causing extensive damage.

If Your Roof is 15+ Years Old it May Have Similar Damage to Vent Pipes and Flashing

Efficient and Effective Roof Repairs in Carlisle PA

These Carlisle homeowners are going to end up getting a new roof within a year or so. In the meantime, they contracted us for a simple yet effective repair of this roof leak to buy them some time. Since they did not want any expensive or invasive procedure on their roof (as they are going to replace it soon), we stopped the leaks by sealing and caulking the problem chimney flashing and installing a new boot over the top of the pipe vent.

The Perma-Boot vent pipe leak repair system completely seals and stops all leaks through the existing flashing.

Pipe Vent Repair & Perma-Boot Installation:

We installed a Perma-Boot vent pipe repair system over the existing roof vent pipe boot and flashing. Each component of this new boot was thoroughly caulked and sealed with a tripolymer sealant. This type of fix will last for decades, and in fact Perma-Boot provides a warranty for the lifetime of the existing shingles. The vent pipe leak in this PA roof is fixed for good. The chimney flashing leak was more complicated...

Chimney Flashing Repair, Seal & Caulk:

We sealed the chimney flashing by applying a tripolymer roof caulking sealant called GeoCel 2300 (a product capable of sealing leaks entirely submerged in water!) around the edges of the flashing. We then sealed all the flashing - from 1" overlapping the brick to 1" overlapping the shingles - with a Flex-Seal spray to ensure that no watter could leak into the home. However, the problem with this chimney flashing was that it was only on the exterior. It should have been installed with step-flashing and counter-flashing.

Our owner Jeff performed these roof repairs himself. Here he is installing a Perma-Boot to stop the old, damaged pipe vent flashing from leaking into the house.

Proper Installation of Chimney Flashing:

Because of the problems with this chimney's existing flashing, we gave the homeowners other options for repairing it. For example, a more permanent fix involving the installation of step-flashing and counter-flashing would completely prevent future roof leaks. This is especially important because the chimney rises from the very bottom of a steeply pitched roof, so the valley where it meets the roof shingles gets a lot of water run-off.

Most chimneys, installed somewhere higher on the roof, are free from heavy water run-off over their flashing. Since this Carlisle home was going to get a brand new roof within the year, the homeowners opted for a simpler fix to buy some time. So we thoroughly sealed and caulked the existing flashing.

This roof leak was caused by failed chimney flashing. We caulked the leak to buy time, but a more thorough roof repair will be necessary eventually.
