Common Flat Roof Problems

Ponding water, failed flashing at walls and penetrations, split seams, and blocked drains are the usual culprits. A flat-roof leak rarely shows up where the water's actually getting in — finding the true source is the job.

Our Repair Process

We trace the leak to its source, repair the membrane and flashing properly, and check the drainage so the problem doesn't come straight back. For buildings, we can follow up with a maintenance plan.

Emergency or Planned: Timing the Repair

An active leak over inventory or a tenant space is an emergency and we treat it like one. But many flat roof problems are caught early, when you can plan the repair for good weather and normal pricing instead of an emergency call. That is the argument for the annual inspection: it converts emergencies into scheduled line items. Either way, the repair itself is done properly, with matched membrane and hand-sealed details, not a bucket of mastic smeared over the symptom.

Frequently Asked Questions

Why does my flat roof keep ponding water?

Usually a slope or drainage issue. We assess whether it's a repair or a drainage correction and fix the actual cause.

Can you repair it in winter?

Often yes — we'll advise whether a durable repair is possible now or whether a temporary fix until spring is smarter.
