Roof Construction Systems
A carpenter’s eye. One complete system.
Harry brings roof carpentry and a whole-roof perspective to projects, from the structure through to insulation, ventilation and finish.
Roof construction, considered together
I’m Harry Andrews. My work is rooted in roof carpentry, and I take a whole-system view of how a roof is put together. The structure, insulation, ventilation, weatherproofing and visible finish each have a part to play.
Roof Construction Systems brings those conversations together. You can ask about a specific element or talk through a larger project where several parts of the roof need to connect.
From the first conversation to the details
Plans, photographs and a clear description of what you want to achieve help us start well. Where a project involves existing construction or other trades, those interfaces belong in the discussion before the scope is agreed.

A straightforward project conversation
You do not need a finished specification to get in touch. Tell me what you know, what is still uncertain and what you would like the roof or space to do. I can explain what information is useful for the next step.
The business is liability insured. Guarantees are available for qualifying work, with durations from 10 to 25 years depending on the service and system. Please ask me to confirm the terms and coverage for your specific proposal.
ROOF CONSTRUCTION. BUILT FOR PERFORMANCE.
