Skylights, Solar Mounts, and Satellite Holes: The Roof Repair Nobody Budgets For in Miami

Every hole in a roof is a decision someone made after the roof was finished. Skylights, solar arrays, satellite dishes, attic fans, mini-split line sets, security cameras, hurricane-shutter anchors — each one interrupts a water-shedding system that was designed to be continuous. In Miami-Dade, where wind pressure drives rain sideways and uphill, these interruptions are responsible for a large share of the leaks that show up in the ceiling and get blamed on the shingles.

This article explains how penetrations fail, what a proper roof repair at a curb or mount looks like, and how to keep an added component from quietly voiding the warranty on an otherwise healthy roof.

Why Penetrations Fail First

A penetration has to do three things at once: seal against water, allow the roof and the attached object to move independently, and stay serviceable. Most failures come from getting one of those wrong.

• Sealant used as the primary defense. Caulk is a secondary barrier with a service life measured in a few years under Florida UV. When it is the only thing keeping water out, the leak is scheduled, not accidental.
• Flashing installed out of sequence. Water management depends on layering: upslope material must lap over downslope material. A curb flashed after the fact, on top of the finished surface, sends water under the covering.
• No allowance for movement. A rigid connection between a moving panel and a fixed curb tears itself apart over a few hundred thermal cycles.
• Fasteners into the wrong substrate. Lag bolts that miss the rafter and land in plywood alone will loosen under uplift, and each loose bolt becomes an open hole.

Skylights and Curbs

Deck-mounted skylights on shingle or tile roofs leak most often at the head flashing and the upslope corners, where debris collects and water slows down. Curb-mounted units on low-slope roofs fail at the curb-to-membrane termination, especially where the curb was built too short — a curb that rises less than about eight inches above the finished surface leaves no room for a proper counterflashed termination. Repairing the glass unit while leaving a short curb in place solves nothing.

Solar Mounts

Solar is common now from Biscayne Park and El Portal to Coral Gables and Doral, and the mounting method determines whether the array is a roofing problem. Properly installed standoffs land in structure, use a flashed base that integrates under the covering, and are documented so future work can be sequenced around them. Racking bolted straight through a tile with a bead of sealant is the version that produces leaks in year three — and repairing it usually means lifting panels, which involves the solar installer as well as the roofer.

Abandoned Holes

Old satellite mounts, removed attic fans, decommissioned plumbing vents, and prior antenna anchors are the least glamorous and most common source of mystery leaks. They are cheap to close correctly — deck patched, underlayment lapped in, covering restored — and they are almost never closed correctly by whoever removed the equipment.

What a Correct Penetration Repair Includes

Ask that the written scope name each of these:

Step	What it means
Expose and assess	Covering removed around the penetration, deck condition documented
Deck repair	Rotted sheathing replaced, not sealed over
Underlayment	New self-adhering membrane lapped shingle-fashion into existing
Metal flashing	Fabricated base, cap, or counterflashing appropriate to the assembly
Fastening	Into structure, with corrosion-resistant fasteners rated for coastal use
Restoration	Covering reinstalled with matched materials; sealant as backup only

If the penetration is part of a permitted alteration — a new curb, a structural mount — the work belongs on a permit with an inspection, and any roofing contractor working legitimately in Miami-Dade will tell you that before quoting.

Protecting the Warranty You Already Paid For

Manufacturer and workmanship warranties are conditioned on the assembly staying as designed. Three habits protect coverage:

1. Coordinate before drilling. Notify the roofer who holds the workmanship warranty before any trade goes on the roof. Most will supervise or perform the flashing themselves for a modest fee.
2. Keep the paperwork. Photos of the flashing before the covering closes are the single most useful document you can own.
3. Bundle timing. If a roof is within a few years of replacement, adding solar first is expensive twice. Sequence a roof replacement and the array together.

Water entering the house through a penetration during a storm is not a scheduling matter — that is emergency roofing, and containment comes before diagnosis. Note too that overflowing gutters at the eave can mimic a penetration leak by backing water up under the edge, so functioning gutter installation is part of ruling causes in or out.

Frequently Asked Questions

Can a leaking skylight be repaired, or does it need replacing?

If the glass unit and seals are intact and the leak traces to flashing, it is a flashing repair. Fogging between panes, cracked acrylic domes, or a curb that is too short generally point to replacement of the unit or curb.

Who is responsible when a solar array leaks?

It depends on who penetrated the roof and what each contract says. Determining that is the first step, which is why a diagnostic that documents the exact entry point is worth doing before anyone starts assigning cost.

Should I remove an unused satellite mount myself?

Removing the bracket is easy; closing the hole correctly is not, because it requires lapping new underlayment into the existing courses. Leave the bracket in place until a roofer can close it properly.

Does a penetration leak mean the whole roof is failing?

Usually no. An isolated curb or mount failure on a roof with remaining service life is a repair. Multiple penetrations failing at once often means they were all installed the same way, on the same day, by the same crew.

Have a Penetration You Do Not Trust?

A skylight, solar mount, or abandoned hole is one of the least expensive things to fix correctly and one of the most expensive to ignore.
