Chimney Flashing & Waterproofing

Water running down beside a chimney usually means failed step flashing, a missing cricket or a cracked crown. We find which, rebuild it, and stop the leak at the masonry line.

The job, explained

Your chimney's flashing and waterproofing are critical barriers against moisture intrusion. Over time, exposure to harsh sun, heavy rains, and hail can compromise these seals, leading to leaks that can damage your attic, ceilings, and walls. Proper maintenance and timely repairs are essential to prevent costly structural issues and mold growth, preserving your home's value and safety.

Rico's Roofing LLC specializes in repairing and replacing chimney flashing, along with comprehensive waterproofing solutions. We understand the specific demands placed on roofs in San Antonio and the surrounding Hill Country. Our skilled technicians use durable materials and proven techniques to create a watertight seal around your chimney, offering lasting protection against the elements.

Why it matters in South Texas

San Antonio's climate, with its intense summer sun, sudden downpours, and occasional hail, places significant stress on chimney flashing and waterproofing. The UV rays can degrade sealants, while hail and high winds can damage flashing and mortar. For homes in areas like Stone Oak or Helotes with complex roofs, or older homes in Alamo Heights, proper chimney protection is vital to prevent leaks and preserve structural integrity against these weather patterns. Our services address these specific regional challenges, offering lasting solutions for local homeowners.

Choices

Materials and methods we use

Step Flashing

Individual L-shaped metal pieces interwoven with roof shingles to create a shingled, watertight barrier around the chimney. This method allows for roof expansion and contraction while maintaining a secure seal against water intrusion.

Counter Flashing

A second layer of flashing, often cut into the chimney's mortar joints, that overlaps the step flashing. This provides an additional protective layer, directing water over the step flashing and onto the roof surface.

Mortar Crown Repair

The top slab of concrete or stone on your chimney, the crown, protects the masonry below. Cracks are sealed or the crown is rebuilt to prevent water from entering the chimney structure from above.

Masonry Sealing

Application of clear, breathable water repellents to the brick, stone, or stucco surfaces of the chimney. This treatment penetrates the material, reducing its porosity and preventing water absorption without altering its appearance.

Step by step

Our process

    Our team performs a final inspection to confirm all work meets our standards for durability and watertightness. We then ensure the work area is clean and free of debris.

Questions

What people ask about chimney flashing & waterproofing

Why is chimney flashing so important?

Chimney flashing creates a watertight seal where your chimney meets your roof. Without proper flashing, water can easily seep into your attic and home, leading to extensive damage such as wood rot, mold growth, and compromised structural integrity. It is a critical component for preventing leaks.

How often should I have my chimney flashing inspected?

It is advisable to have your chimney flashing inspected at least once a year, ideally as part of a general roof inspection. After severe weather events like hailstorms or strong winds, an immediate inspection is recommended to check for any damage that could lead to leaks.

Can I repair the flashing myself?

Repairing chimney flashing requires specialized knowledge of roofing and masonry, proper tools, and safety equipment for working at heights. Improperly installed flashing can cause more harm than good. It is best to entrust this work to experienced roofing professionals to ensure a watertight and durable repair.

What are the signs of damaged chimney flashing?

Common signs include water stains on your ceiling or walls near the chimney, dampness in your attic, visible gaps or cracks in the flashing material, rust on metal flashing, or loose/missing shingles around the chimney base. Any of these indicate a potential water entry point.
