Chimney Cricket Construction

What This Service Involves

Some chimneys are simply too large or oddly positioned for a standard prefabricated diverter, so we construct a cricket from scratch to fit the exact geometry of your roof. Our carpenters build the ridge and valleys of the saddle to match your roof pitch precisely, ensuring water is thrown well clear of the masonry on all sides. Every joint is sheathed, underlaid, and metal-flashed to handle the sustained runoff typical of a Western Washington winter. Custom construction guarantees the diverter performs on a broad chimney where an off-the-shelf part would leave gaps.

Benefits

Purpose-built to fit oversized or irregular chimneys that stock crickets cannot; framed to your exact roof pitch for maximum water diversion; fully sheathed and flashed for heavy, sustained Northwest runoff; delivers a permanent structural solution rather than a temporary patch

Our Process

1) Take detailed measurements of the chimney footprint and roof slope; 2) Frame the custom saddle with matched ridge and valley angles; 3) Apply sheathing, underlayment, and interwoven flashing; 4) Finish with roofing and verify balanced runoff on both slopes

What Affects the Cost

Overall chimney dimensions and cricket footprint; framing labor for a custom saddle; sheathing, underlayment, and flashing materials; roof pitch and structural tie-in requirements; height and access for construction

Best Time of Year

Build custom crickets during the summer building season so all framing and flashing cure and seal before the rainy months.
