You already know the buildings.
- Chinook Regional HospitalAcute care · never closes
- University of LethbridgeCampus
- Lethbridge PolytechnicFormerly Lethbridge College
- Cor Van Raay YMCA≈256,000 sq ft · third-largest in North America
- Lantic SugarCanada's only sugar-beet refinery
Not one of them can be closed for a roof. A hospital runs at three in the morning; a refinery runs straight through the beet campaign; a campus fills every September. That is not a portfolio — it is a list of buildings that had to stay open while we worked on them. From C & H Roofing's own project record.
The building stays open.
- We open only what we can close.
- Work proceeds zone by zone, never across the whole deck at once.
- Every day ends watertight.
- Crews work to stopping points, so an overnight thunderstorm never finds an open deck.
- You call a person, not a queue.
- One point of contact for the length of the job.
A facility manager is not really buying a membrane. They are buying the absence of an incident — no water over an operating room, no shutdown, no explaining to a board why the server room flooded. The roof is the easy part. The sequence is the job.
1941
Ask who signs the work.
Malcolm Charlton and Clarence Hill opened a shop in Lethbridge in 1941. The roofing side of it never stopped, and in 2021 it took its own name: C & H Roofing Ltd.
Our manager, Alan Roberts, sits on the Canadian Roofing Contractors Association's National Technical Committee — the body that takes up the technical questions facing the trade across Canada. It is an unusual thing for a Lethbridge roofing shop. We have never mentioned it before.
- ARCAAlberta Roofing Contractors Association — accredited contractor
- CRCACanadian Roofing Contractors Association — active member
- LCALethbridge Construction Association — member
One drop stops the line.
Lethbridge sits at the centre of Canada's agri-food corridor. Over an open food line, a single drop of roof water is not a maintenance item — it is an audit finding, and audit findings stop production.
We have roofed the refinery. We know what is under the deck, and we know what a shutdown costs the people who work beneath it.

The last layer of a roof is a promise.
Anyone can print a long number on a warranty. The number is almost always for the material. The workmanship — which is where roofs actually fail — is covered by the company that installed it, for exactly as long as that company exists.
C & H is an ARCA-accredited contractor: one of three in Lethbridge. Accreditation takes about a year — board review, site evaluations, peer review, an audit of safety record and workmanship. It is why we may issue the certificate below, and why most of the names above us in a search result simply cannot.
ARCA Warranty Certificate
- Term
- 5, 10 or 15 years — workmanship, against leaks.
- Inspection
- An independent ARCA inspector attends during construction, and again at year two.
- The clause
- Repairs remain covered

That sentence is the whole point, and it is the smallest type on this page. The warranty outlives us.

Nobody knocks on your door about this one. You get what you have, how old it is, and the year it becomes a capital decision — in writing.
We are also hiring. You would be working on the hospital.
