GAF Timberline HDZ Roof Repair in Columbia, MD: A Recent Project

We began by removing the shingles around the chimney and exposing the damaged wood. Several areas showed signs of water saturation, so we removed all compromised decking and replaced it with solid, dry material. This ensures a strong base before reinstalling any roofing components.

Next, we replaced the chimney flashing. Our team used a reglet-style installation, which involves cutting into the mortar joints on the front and back of the chimney. This method creates a tight, long-lasting seal that keeps water from slipping behind the brick and entering the home.

We then built and installed a chimney cricket. A chimney cricket is a small, peaked structure placed behind the chimney. Its purpose is to split water and divert it around the chimney instead of letting it pool or sit against the brick. Without a cricket, water often collects at the base of the chimney, leading to leaks and wood rot. Adding this structure greatly improves drainage and protects the entire area long-term.

We also installed kick-out flashings to guide water into the gutters instead of letting it run down the siding or into wall joints. New wall flashings were added to seal all vertical transitions around the chimney and adjoining roof surfaces.

After all structural and flashing work was complete, we installed new underlayment and finished the repair with GAF Timberline HDZ shingles in Pewter Gray. These shingles match the existing roof and restore a clean, uniform appearance.
