Where Roof Leaks Usually Start

Most leaks are not “random”. They usually come from weak points like joints, flashings, outlets and gutters. We inspect first, then choose the correct waterproofing method.

Flashings & penetrations
Pipes, skylights, walls, chimneys.
Valleys & ridges
Poor overlaps, cracks, movement.
Flat roofs & parapets
UV damage, ponding, lifting seams.
Gutters & outlets
Blocked outlets, rust, failed sealants.

Our Waterproofing Process

Clean preparation + correct detailing is what makes it last.

Inspection & leak tracing
We confirm the true source (not only where water shows).
2
Surface preparation
Clean, dry, prime, repair cracks, secure loose edges.
3
System application
Torch-on or liquid waterproofing depending on roof type.
4
Detailing & finishing
Flashings, outlets, overlaps, UV protection and neat finish.

Waterproofing FAQs

How long does waterproofing take?

Small repairs can be done same day. Full roof waterproofing depends on size, prep needs and drying time. We give a clear timeline after inspection.

Do you fix the leak source first?

Yes. We inspect flashings, valleys, outlets, gutters and joints. Waterproofing works best when the correct source is treated.

Can I paint over waterproofing?

Some systems allow compatible topcoats. We recommend the right finish for UV protection and warranty.
