A building envelope maintenance manual, often referred to as a BEMM, is a helpful and practical guide for taking care of a building’s exterior components over time.  It focuses specifically on the building “envelope” – the parts of a building that protect it from weather and the outside environment.

 

What does the building envelope include?

• Roofs
• Exterior walls (cladding, siding, stucco, brick)
• Windows and doors
• Balconies and decks
• Sealants, flashing, and waterproofing systems
• Foundations

 

What does a BEMM tell you?

• What needs to be maintained
• How often to check it
• What problems to look for
• What to do to prevent damage

 

It is designed to prevent issues such as leaks, mold, rot, and structural deterioration before they become expensive repairs.

 

What is inside a typical BEMM?

System descriptions:

• Explanations of materials and how the envelope is built

 

Maintenance schedule:

• Annual roof inspections
• Cleaning gutters and drains
• Resealing joints every few years

 

Inspection checklists indicating things to look for:

• Cracks or gaps
• Water stains
• Failing caulking
• Condensation

 

Repair guidance

• When something is minor vs. when to call a professional.

 

Warranties and contacts

• Information about installers, materials, and coverage.

 

Maintenance logs

• A place to record inspections and repairs over time.

 

Why is a BEMM so important?

Without a BEMM:

• Small issues often go unnoticed
• Water damage can spread inside walls
• Repair costs become much higher

 

With a BEMM:

• Buildings last longer
• Maintenance is scheduled and predictable
• Owners save money over time

 

A BEMM is like a maintenance playbook for a building’s exterior – a clear plan to keep the structure dry, protected, and in good condition year after year.

 

One of the many services that BC Building Science offers to new homeowners is the Building Envelope Maintenance Manual, a valuable tool to help new owners understand their envelope maintenance responsibilities.  We are also pleased to offer a complimentary meeting with a building’s Strata Council to both review the manual and offer an opportunity to ask questions.
