LAVENDA BUILDING SYSTEMS SDN BHD
Roofing Specialist Malaysia
Lavenda is a roofing specialist in Malaysia handling design, engineering, and installation, backed by SIRIM, ISO 9001:2015, and CIDB certification, and over 20 years of experience.
THE ROLE OF A ROOFING SPECIALIST
What Does a Roofing Specialist in Malaysia Actually Do?
A roofing specialist is different from a general contractor or a repair-only roofer. Instead of installing whatever material a client hands them, a specialist is involved from the start: selecting the right system, working out the engineering behind it, and carrying that through to installation and aftercare.
A general contractor typically installs to a given plan. A roofing specialist writes the plan — covering design, material selection, and the drainage and load calculations that keep a roof performing in Malaysia's weather.
ENGINEERING-LED, NOT INSTALL-ONLY
The Full Scope of a Roofing Specialist's Work
Most roofing contractors work from a plan someone else drew up, and stop once the sheets are on. Lavenda's scope goes further.
Shop Drawing & BIM Detailing
Detailed, CAD-based drawings and centralised project data that reduce construction errors and improve coordination.
Drainage & Gutter Calculation
Engineered drainage and gutter sizing based on the building's actual roof specifications, reducing water damage risk.
U-value & STC Calculation
Thermal performance calculations suited to Malaysia's climate, alongside acoustic calculations where sound transmission matters.
Fabrication & Roll On Site
On-site roll-forming that removes transport length limits, reduces handling damage, and speeds up installation.
WHAT WE SPECIALISE IN
Roofing Products & Systems Lavenda Specialises In
Lavenda's technical scope is backed by an in-house product range, so the same team responsible for the engineering also supplies and fabricates the materials.
Metal Roofing & Cladding
Engineered to meet specific acoustic (STC) and thermal (U-value) requirements while standing up to Malaysia's weather.
Lightweight Truss
Improves structural strength and efficiency, with fire resistance, termite resistance, and faster construction.
Truss Components / Accessories
In-house accessories manufactured with TRUECORE® steel for guaranteed compatibility and strength.
Rainwater Goods
Gutter and drainage components designed to work as part of a coordinated roofing system.

Why Choose Lavenda as Your Roofing Specialist
Lavenda covers the full process from design through material selection, fabrication, and installation, rather than only installing whatever a client supplies. Every material is genuine and marked for traceability, meeting industrial standards — a level of accountability most repair-only contractors don't offer.
With over 20 years of experience, certification from SIRIM, ISO 9001:2015, and CIDB, and BlueScope-grade coated steel behind every product, Lavenda's role as a specialist starts well before the first sheet goes on the roof.
Frequently Asked Questions
What does a roofing specialist in Malaysia do?
A roofing specialist handles more than installation. The work starts with selecting the right roofing system for a building’s use, location, and budget, then moves into the engineering behind it — shop drawings, drainage calculations, and thermal or acoustic requirements — before installation even begins. This differs from a general contractor, who typically installs to a plan someone else already drew up. A specialist is also usually the point of contact for aftercare, since they understand the system’s design intent rather than just how it was fitted.
How do I choose a roofing specialist vs. a general contractor?
A general contractor typically installs roofing to a plan or material list someone else has already decided on. A roofing specialist is usually involved earlier, helping select the material and system, running the calculations that determine drainage, thermal, and acoustic performance, then carrying that through to installation. If your project has any design complexity — a large roof area, drainage challenges, or specific performance requirements — a specialist is generally the safer choice, since issues can be caught at the design stage rather than after installation.
What certifications should a roofing specialist have?
Look for certifications that speak to both the material and the process. ISO 9001:2015 confirms a consistent, quality-managed production process. SIRIM product certification validates that materials meet Malaysian national standards. CIDB registration reflects compliance with Construction Industry Development Board requirements, which matters for larger commercial and government projects. Together, these give a level of assurance that goes beyond a contractor’s own claims, since they’re independently verified.
How much does professional roofing installation cost in Malaysia?
Costs vary depending on the roofing system, roof size and complexity, and whether the project needs additional engineering work such as drainage or acoustic calculations. Concealed-fix (standing seam) systems typically cost more than exposed-fastener metal decking due to the cleaner finish and more complex installation. Roof pitch, access difficulty, custom fabrication, and additional engineering for large or architecturally complex roofs all push cost up. A project-specific quote is the most reliable way to get an accurate figure.
Do you handle both design and installation?
Yes. Lavenda covers the full process rather than only supplying materials or only installing them — shop drawing and BIM detailing, roof drainage and gutter design calculations, U-value and STC (acoustic) calculations, fabrication (including on-site roll-forming for large projects), and installation. Handling design and installation under one team keeps the engineering and the way a roof is actually built consistent, rather than split across a designer and a separate installer who may interpret the plan differently.
