Roof, walls, and transitions
The whole building envelope.
The roof, walls, windows, and foundation all have to keep water and air out together. Most envelope leaks happen where one system meets another: roof-to-wall transitions, parapets, window perimeters, and penetrations.
- Coping
- Counterflashing
- Membrane
- Cover board
- Insulation
- Deck
Where water gets in
Roofs fail at the edges. Most of the water we trace is at a transition, not in the middle of a field of membrane.
- Where the roof meets a wall
- Parapets, coping, and the edge of the roof
- Counterflashing and flashing at those transitions
- Penetrations, window perimeters, and joints in the wall
- Sealant that has cracked or pulled away
What you notice
- A stain or a drip at the top of a wall
- A wet spot that is not under an obvious hole in the roof
- Water or a draft at a window edge or a panel joint
- Coping or flashing that looks loose from the ground
What we do
- Envelope assessments that find where water and air are getting in
- Roof-to-wall flashing, parapet caps and coping, and counterflashing
- Edge and transition flashing repaired or replaced with the roof and the wall
- Sealant and joint replacement at windows, panels, and expansion joints
- Air and water barrier repairs and details at penetrations
- Written findings with photos and a prioritized repair list
- NRCA member. Built to NRCA guidelines and the manufacturer's details.
