Ask a commercial roofing question.

A direct line to the TRS technical team for questions about a specific roof, a defect you cannot explain, or a specification you are reviewing. Where an answer is useful to others, TRS may publish an anonymised version in the knowledge hub, only with your permission.

• · Technical questions only. If you need someone on the roof, use book a roof survey — the initial survey and site visit are free of charge.
• · The more detail you give (building type, roof type, photos held), the more specific the answer.
• · Your submission is stored securely and only visible to TRS staff.
