Skylights, Chimney & Flashing Work

Skylights, chimneys and valleys

Overview

Skylights & Flashing done the right way

Flashing is where roofs leak. Chimneys, sidewalls, valleys, skylights and dead-valley details take skill that a shingle crew running for square footage rarely slows down for.

We replace skylights with modern deck-mounted units and factory flashing kits, rebuild chimney flashing with proper counterflashing cut into the mortar, and line valleys in metal.

Common questions

Should skylights be replaced with the roof?+

If a skylight is over 15 years old, yes — replacing it later means disturbing new shingles.

Can you add a skylight to a dark room?+

Yes, including solar tubes for hallways and bathrooms where a full skylight won't fit.

Is caulk ever the answer?+

As a temporary stop only. Real flashing repairs use metal and layering, not sealant.
