Visiting my sister marlene in thunder bay this summer 2012 there was as usual a project like every other time.
Low slope roof to wall flashing.
Turbo set polybrite 70.
Badly corroded flashing will need to be replaced.
Normally used with a low slope.
Open valleys have metal flashing to protect this critical area of the roof.
Polystick tu plus.
Sl 1 1 5 sl 1 75 ml 1 1 5 ml 2 ns 1 1 5 exposed fastener panels.
Then apply standard asphalt shingles over the membrane.
The edge of the roof has thin metal flashing that helps water drip off the roof without damaging the home or causing a leak.
Low slope metal accessories.
Flat coil stock.
Roofing cement can dry out and crumble away exposing joints to water.
Self adhesive flashing membrane under the shingles prevents leakage on low slope roofs.
For a low slope residential roof there are two main options.
To seal the juncture of the roof membrane with other building components such as walls edges and penetrations.
To connect the flashing material to other building materials such as masonry concrete metal and wood.
Flashing application requirements are similar for all types of low slope roof materials and systems.
Drip edge metal valley flashing dormer chimney and kickout flashing are types of roof flashing that shed water away from the connections between roofs walls chimneys and other building assemblies.
Although surprisingly there was only one leak in the old roof.
Low slope roof slip metal flashing for the roofing industry is available in standard 10 lengths from sheet metal supply.
It s much easier to reseal the flashing than it is to patch a water stained wall or ceiling.
Troubleshooting in advance use.
If you don t direct water from the roof into a gutter it can pour into the wall.

Fasten loose nails and cover exposed nail heads with roofing cement.
Renew flashing seals by chipping out old caulking and mortar along the edges of the flashing.
While some skylight manufacturers include flashing in their products sometimes roofing professionals have to create it or purchase it separately.
And in our experience when a single piece of flashing extends only a few inches under the shingles especially on a long roof slope and worse on a roof that happens to slope slightly towards rather than away from the abutting vertical building wall the accumulated roof drainage water near the bottom end of the roof wall intersection will overwhelm the width of the flashing and because it is not directed back out on top of successive shingle courses it leaks into the building or building.
