Roof and Chimney Waterproofing in Orlando, FL

Roof and chimney waterproofing means rebuilding the details that let water past an otherwise sound roof: chimney counterflashing and crowns, wall abutments, skylight curbs, pipe penetrations and valley membrane. It is detail work, not a coating. Orlando Roofing is licensed and insured and quotes free in writing.

What waterproofing covers

Chimneys first, because they are the worst offender on any pitched roof. A chimney interrupts the water running down the slope, and it needs a set of parts working together: step flashing woven into each shingle course, counterflashing let into the masonry rather than caulked to its face, a cricket on the uphill side to split the flow on wider stacks, and a sound crown on top.

Then the rest of the penetrations. Pipe boots, vent collars, satellite mount feet, solar attachments and anything else somebody screwed through the roof over the years.

Then transitions. Where a roof meets a wall, where a low-slope section meets a pitched one, and where an addition ties into the original house.

Why it matters in Central Florida

Wind-driven rain is the reason. A vertical downpour is easy for a roof to handle. An afternoon thunderstorm pushing rain sideways at 40 mph gets in behind anything that relies on a bead of sealant, and hurricane season does it harder.

UV is the other. Exposed sealant, mastic and rubber pipe collars degrade fast in this sun. A caulk joint that was watertight the day it went in is a liability by year six, and rubber boots split around year eight to twelve here.

Then humidity. Masonry chimney crowns crack, absorb water and stay damp, and that moisture works into the flashing joint from behind.

The pattern homeowners notice: a stain that appears only after certain storms and dries up in between. That is almost always a detail failure, not a hole.

The process

We inspect every penetration and transition, not just the one near the stain, then check the attic where there is access to see where water has actually been.

The fix is metal and membrane, done properly. Step and counterflashing replaced rather than sealed over. Crickets built where the chimney width calls for one. Crowns repaired or recast. New boots on pipes. Peel-and-stick membrane in valleys and at critical laps. Sealant is used to finish a joint, never to make one.

Written scope before work starts, with each detail listed separately so you can see what you are paying for.
