From worn and weathered to strong and protected — this barn just got a major upgrade. 👏

We recently completed this barn roof installation using:
• GAF Timberline HDZ shingles in Shakewood
• GAF FeltBuster underlayment
• Ridge vent ventilation system

If your roof is starting to show signs of age or storm wear, we’re always happy to provide a free inspection and honest recommendations.

Another happy homeowner. We appreciate the kind words and the opportunity to take care of this project from start to finish.

A recent chimney repair we completed where our team formed a brand new crown to help protect the chimney from future wear and water damage.

It’s one of those areas homeowners don’t always notice right away, but when the crown starts to break down, it can lead to bigger issues over time if left unchecked.

Glad to get this one cleaned up and protected the right way.

If your chimney is showing signs of wear, we’re always happy to take a look.

Not every roof problem starts with a major leak. 🏠

Sometimes the warning signs are much smaller — and easier to miss.

If your roof is getting older, losing shingles, showing signs of staining, or taking a beating from storms, it may be time to have it looked at before a small issue turns into a costly repair.

At G J Goss, we’ve been helping homeowners protect their homes for over 40 years with honest evaluations and quality workmanship you can trust.

If you’ve noticed any of these signs, we’re always happy to take a look and provide a free, no-pressure estimate.
