FAQs About Rooftop
Deck Waterproofing

Do I really need sheet metal flashing?

Yes. If your property has areas exposed to rain, runoff, or moisture, flashing is critical for preventing leaks and damage.

Absolutelyaa We retrofit flashing to reinforce older buildings and stop existing leaks before they get worse.

With proper installation, it can last decades. Routine inspections guarantee it stays in top shape.

Definitely. No two buildings are the same, and off-the-shelf flashing often leaves weak spots. We custom-cut and shape sheet metal flashing to fit your roof, windows, and walls perfectly.

Yes, and it’s often the best solution. Older buildings settle over time. They create tiny gaps where water sneaks in. Properly installed flashing bridges those gaps and reinforces vulnerable spots without compromising the building’s original structure.

Look for rust, cracks, or sections that have pulled away from the surface. If you see water stains inside your property, flashing failure could be the culprit. Even minor damage can lead to costly repairs. So it’s worth having a pro inspect it before small leaks turn into big problems.
