How Long is the Warranty for Warehouse Roofing Materials and Installation Services at PT. Bajaringan Industri Sejahtera?

Introduction

A warranty is one of the primary considerations for industrial players when selecting a warehouse roofing construction service provider. An industrial warehouse is a strategic asset housing high-value products, machinery, and business operations. Therefore, the decision to choose a roofing contractor should not be based solely on the lowest price, but on material quality, technical competence, and — equally important — written warranty certainty.

PT. Bajaringan Industri Sejahtera stands as a specialist in light steel roofing construction for industrial and warehouse buildings. We are committed to providing clear, measurable, and genuinely claimable written guarantees for every light steel material and installation service we deliver. This article will detail the duration, coverage, claim procedures, and terms and conditions of the warranty applicable at our company, so that you as an industrial player can make a confident decision.

Light Steel Material Warranty (Main Structure)

Warranty Duration

10 years from the date of work handover (Berita Acara Serah Terima/BAST).

Warranty Coverage

This warranty guarantees the strength of the light steel frame structure, including:

• No excessive deflection on trusses, purlins, or battens beyond permitted technical tolerances.
• No cracks or fractures at joints and light steel profiles.
• Material conformity with SNI 7971:2013 on Light Steel for Building Structures, including material thickness (minimum 0.75 mm for main structures), coating layer (AZ100 or equivalent), and steel grade (G550).
• Failure due to manufacturing defects such as pores in the coating layer, non-conforming thickness, or other fabrication defects.

Warranty Exclusions

The structural material warranty does not apply to damage caused by:

• Natural disasters such as earthquakes exceeding the scale specified in the structural design, extreme typhoons, or major floods.
• Structural modifications without written approval from the technical team of PT. Bajaringan Industri Sejahtera.
• Corrosion due to extreme chemical environments (e.g., acid, fertilizer, or salt factories) that were not reported and not anticipated from the initial planning stage.
• Improper maintenance, including overloading beyond the original design.

Roofing Material Warranty (Spandek/Zincalume/Metal Tile)

Warranty Duration

• 5 years for color fastness (if using colored/coated roofing).
• 8 years for leak resistance due to material defects.

Warranty Coverage

The roofing material warranty guarantees:

• Material will not perforate due to manufacturing defects.
• No massive paint peeling on colored roofing.
• No leaks caused by manufacturing defects, such as non-conforming material thickness (e.g., 0.35 mm spandek claimed as 0.40 mm), coating layer failure (AZ or Z), or rolling defects during production.

Warranty Exclusions

The roofing material warranty does not apply to:

• Leaks due to installation errors — these fall under the workmanship warranty, not the material warranty.
• Scratches or mechanical damage occurring during installation by other parties.
• Corrosion due to direct contact with chemicals, fertilizers, or corrosive industrial waste.
• Damage from falling objects, extreme hail, or vandalism.

Installation Service Warranty (Workmanship)

Warranty Duration

1 full year from the BAST date.

Warranty Coverage

The workmanship warranty guarantees neatness and precision of installation, including:

• No leaks at screw joints and overlaps between roof sheets.
• Tight bolts and screws — none loose, stripped, or detached.
• Roof flatness and slope according to the original design, preventing water ponding that accelerates corrosion.
• Neat gutters, flashing, and ridge caps so rainwater flows perfectly to drainage channels.
• Conformity of purlin and batten spacing with the approved technical specifications.

Warranty Exclusions

The workmanship warranty does not apply to damage caused by:

• Improper maintenance, such as stepping on roof areas not designated for foot traffic.
• Load changes on the roof (adding AC units, solar panels, or other equipment) without written permission.
• Repair or modification work performed by unauthorized third parties.

Warranty Claim Procedure

We implement a transparent and well-documented claim procedure:

1. Reporting: The customer must report a potential claim in writing (email or official letter) within a maximum of 7 working days from discovering signs of damage.
2. Verification: The technical team of PT. Bajaringan Industri Sejahtera will conduct an on-site survey within 3–5 working days to verify the cause of damage — whether material, workmanship, or external factors.
3. Repair/Replacement: If proven within warranty coverage, we will perform repairs or material replacement at no additional cost, except for special access costs such as crane or specialized scaffolding rental if required.

General Terms and Conditions for Warranty Validity

For the warranty to be claimable, the customer must meet the following conditions:

• Payment: The warranty is only valid if the customer has settled all payment obligations per the contract.
• Maintenance: The customer must perform routine cleaning (at least once every 6 months) of dirt, leaves, or foreign objects that may cause corrosion and gutter blockage.
• Documentation: The warranty is void if the customer cannot present the original warranty certificate and BAST.
• Force Majeure: The warranty does not cover damage due to war, riots, or government policies causing drastic changes to the project environment.

Comparison with Industry Standards

The average material warranty in the warehouse roofing construction market is 5–10 years, but many service providers do not offer a separate workmanship warranty. Often, leak claims due to poor installation are rejected on the grounds of "that's the installer's responsibility, not ours."

PT. Bajaringan Industri Sejahtera provides a full 1-year workmanship warranty — an added value rarely offered by competitors — as a form of professional responsibility and confidence in the quality of our workforce. The combination of a 10-year structural material warranty, 5–8 year roofing material warranty, and 1-year workmanship warranty makes our warranty package one of the most comprehensive in the industry.

Conclusion

PT. Bajaringan Industri Sejahtera provides a layered warranty covering structural material (10 years), roofing material (5–8 years), and installation services (1 year) with transparent terms and conditions. This warranty is a manifestation of our commitment to quality and industrial customer satisfaction across Indonesia. Make sure you understand the claim procedure and exclusions so that your warranty rights can be utilized optimally.
