Roof Consulting Services
We all need a roof over our head – whether it be for basic shelter or protection for a multi-building institutional facility.
But not all roofs are created equal – how does yours measure up? Was it installed correctly? Will it last another year, and are there any action requirements required now?
Do you call a roof contractor, or a roof consultant? The answers or opinions you receive may have significant differences.

Consulting services are based on each project parameters and a detailed proposal will be provided.

About Petra:
In construction and building envelope litigation, a case often hinges on one question: Can this technical opinion survive cross-examination?
Founded in 2014, Petra Contract Services Ltd. was established to provide a dedicated, senior-level alternative to large multi-disciplinary firms. Where volume-driven consultancies frequently delegate field assessments to junior staff, Petra delivers hands-on principal involvement, disciplined data collection, and objective technical analysis on every file.
Our value to legal counsel rests on three pillars:
Strict Neutrality: Petra has zero commercial affiliations with roofing contractors, product manufacturers, or material suppliers. Our findings are conflict-free, objective, and insulated from bias—protecting counsel’s credibility in discovery, mediation, and trial.
Court-Defensible Methodology: From origin-and-cause leak investigations to complex building envelope failures, our assessments are strictly anchored in applicable Building Codes, ASTM standards, and manufacturer specifications. Observations are documented to litigation-grade standards alongside credentialed specialists, including Registered Roof Observers (RRO) and ARCA Accepted Inspectors.
Commercial Context: In addition to forensic reporting, Petra actively specifies, tenders, and administers multi-million-dollar roofing contracts every year. This real-world operational oversight ensures our Standard-of-Care opinions, defect analyses, and cost-of-repair evaluations are pragmatic, commercially defensible, and grounded in industry reality.
Whether retained for pre-litigation risk analysis, formal expert reporting, or trial testimony, Petra provides clear, authoritative building envelope expertise that helps counsel resolve disputes effectively.
It gives counsel an immediate benchmark they respect while remaining completely accessible to property owners and insurers reading the profile.
