Concrete roof leak: possible causes and when sealing helps
A leak is an observation, not a diagnosis. Before assuming that sealing is the answer, it helps to understand what FEMA and NRCA say about standing water, drainage, and visual inspections. Housy coordinates roof sealing requests. This information does not identify the cause of a leak at your property or promise that sealing will stop it.

Concrete roof leaks: ponding, drainage, and maintenance
According to FEMA P-2020, «Mitigation Assessment Team Report: Hurricanes Irma and Maria in Puerto Rico» (2020), the assessment team observed ponding on flat concrete roofs. The report describes inadequate drainage, insufficient slope, maintenance issues, and slab deformation among conditions associated with that accumulated water. These are documented observations from FEMA's report, not a diagnosis of every concrete roof in Puerto Rico.
A request for roof sealing service should keep that distinction clear. You can describe where you noticed water and what you know about the roof without deciding which reported condition applies. FEMA's observations provide context for questions about a roof. They do not establish that your property has a drainage problem, that its slab has deformed, or that sealing alone addresses the reason for water entry.
Blocked or insufficient drains and roof slope
According to FEMA P-2020, inadequate drainage included drains that were too few or too small, while maintenance issues included blocked drains. The report also identifies insufficient slope and slab deformation as conditions associated with ponding. A list of possible conditions is not a checklist for diagnosing your own roof. The source records what its assessment team observed; it does not determine which condition is present in a new request.
If the property is in Toa Baja, include that municipality and the roof details you already know. Do not climb onto the roof just to identify a drain or investigate a slope before contacting Housy. It is acceptable to leave an unknown detail as a question. Tell us your municipality and we'll confirm coverage. The property's location does not establish the cause of a leak or confirm service availability.
When sealing may help—and when structural questions remain
According to Puerto Rico's Law 281-2000, Article 2, waterproofing is the treatment of a surface or structure to prevent water and related moisture from passing through it. That describes the intended purpose of the treatment. Whether sealing helps with a particular leak depends on its cause and the roof's condition. The definition does not establish that sealing is the answer to every sign of water inside a building.
FEMA P-2020 mentions slab deformation in its discussion of ponding, but that observation does not diagnose your slab. This page cannot determine whether a structural evaluation is needed or what such an evaluation would involve. Keep unresolved questions separate from the service request. Understanding what affects the price begins with the scope under discussion, not with an assumed diagnosis. A request from Caguas also requires coverage confirmation; the municipality page does not settle that question.
Visual inspections at least twice a year and after severe events
According to NRCA's «Maintaining residential roof systems», written by Mark S. Graham in Professional Roofing in October 2013, owners should visually inspect roofs at least twice a year and after severe weather events, such as a hurricane. This is maintenance guidance from NRCA. It is not a schedule of visits by Housy or a statement about how long a sealing system performs.
According to the same NRCA article, owners without the necessary experience and equipment should not access or walk on roofs or attempt repairs. A recommendation to inspect visually should not be read as an invitation to climb onto a roof. When asking about roof sealing in San Juan, use the information you can share safely. You do not have to expose yourself to roof-access risks to complete the request.
How to request roof sealing without assuming a diagnosis
Begin with the roof area you want addressed, its current condition, and the questions prompted by the leak. Separate observations from conclusions: tell Housy what you noticed, not a cause you cannot confirm. For a property in Bayamón, include the municipality along with that context. Tell us your municipality and we'll confirm coverage. Choosing a coating is not required to open the conversation.
Housy coordinates the request. We confirm scope and price with you before we start. That coordination does not establish a structural diagnosis or promise that a particular source of water entry will be resolved. You receive the service details and, where applicable, photographic evidence. We review the result with you. Your request does not book an appointment; a date and time are confirmed separately from sending the initial message.
Frequently asked questions
Why is my concrete roof leaking?
This page cannot determine the cause. According to FEMA P-2020, ponding was observed in connection with inadequate drainage, insufficient slope, maintenance issues, and slab deformation. Those general findings do not diagnose your roof.
Will sealing stop the leak?
That outcome is not promised. Sealing may help depending on the cause and current roof condition. Requesting sealing does not establish that it is the appropriate answer to a particular leak or replace an evaluation that may be needed.
How often should I inspect my roof?
According to NRCA's «Maintaining residential roof systems» (2013), visual inspections are recommended at least twice a year and after severe weather events, such as a hurricane. This is source-based maintenance guidance, not a Housy service schedule.
Should I climb onto the roof to check it myself?
According to NRCA, owners without the necessary experience and equipment should not access or walk on roofs or attempt repairs. Do not climb onto a roof to gather information for a service request.
