Local chase cover replacement for Rio Pinar homes

A pitched or hipped top for wider chases

Wide chases, and chases with two pipes, can outgrow simple creases. A fabricated pitch, sometimes built as a shallow hip, gives the sheet a true slope from the collar out to each side. The Majestic installation manual we work from pitches the chase top downward, away from the pipe opening, by a quarter inch per foot or more. The shape we recommend follows the size of your chase, the number of openings and the instructions for the installed system.

Copper covers and metal compatibility

Copper chase covers are chosen mostly for appearance, and they weather from bright metal toward brown and eventually green. Copper should not touch or drain onto galvanized parts, because the zinc coating is used up faster in contact with other metals, as the American Galvanizers Association explains. If copper is your choice, we check what it will touch, including the storm collar, flashing and fasteners, and specify compatible parts so the upgrade does not shorten the life of its neighbors.

Protecting the chase while the cover is made

When the old cover is leaking badly, the wait for fabrication is a fair concern. If temporary protection is needed between the measuring visit and installation, we explain what it will be and what it can and cannot do. A temporary measure limits exposure while leaving the corrosion and any damage beneath it for the permanent repair. If we advise it, keep the fireplace unused until the new cover and any related work are complete. We do not charge for temporary protection as though it were the repair, and the estimate keeps the two apart.

What we check while the top is open

The time the cover is off gives the only full view of the chase top, so we use it. Findings are recorded in writing, and anything outside the cover replacement is priced as its own item for you to approve or decline.

• The outer casing of the chimney pipe, for rust or damage
• The joints where pipe sections lock together
• The edges of the framing and sheathing at the top
• Debris, nests or wet insulation inside the enclosure
