What Should a Roof Penetration Register Record Before PV Work

Record each existing or proposed roof penetration as a separate interface with an owner, location and detail reference. The register helps teams avoid treating every pipe or cable entry as the same condition. It does not prescribe a sealant, flashing design or permission to introduce new openings.

Practical review checklist

· Identify the entry. Give each pipe, duct or cable interface a stable identifier tied to the roof plan.

· Record the roof context. Describe known roof layers, nearby seams and observed condition, with gaps in the record left explicit.

· Assign review. Identify the roof-system supplier, installing contractor and project reviewer responsible for the detail.

· Keep closure evidence. Retain the accepted detail, inspection record and relevant as-built photographs for each completed interface.

When to request clarification

Hold a proposed new opening until the roof and structural reviewers confirm its design and responsibility. Existing service penetrations are not automatic approval for additional PV entries.

Questions buyers ask

Can one approved detail cover every entry? Only where the responsible reviewer confirms its applicability to those specific conditions.

What should be recorded when information is missing? Record the missing evidence, responsible reviewer and condition that must be resolved before the affected decision.

Information to send with an enquiry

Send an indexed penetration plan, existing detail records, photographs and a list of proposed new services.

This is a project discussion checklist, not an installation instruction or an approval. The selected manufacturers, project engineer and local authority must confirm the applicable requirements.

光伏施工前的屋面穿透点清单如何建立

每个既有或拟新增穿透点应独立记录位置、责任人和详图编号，避免把所有管线入口视为相同情况。清单本身不是密封材料、泛水设计或新增开孔许可。

实用核对清单

· 识别入口：每个管道、风管、线缆接口使用固定编号并关联平面图。

· 记录构造背景：注明已知层次、附近接缝及观察状态，缺失信息明确保留。

· 分配审查：列明屋面供应商、施工方及项目审阅者。

· 保存闭环证据：每个接口关联确认详图、检查记录和竣工照片。

需要澄清的情况

新增开孔须待屋面及结构审阅者确认设计和责任；既有服务穿孔不等于新增光伏入口获准。
