A continuous drainage mat rainscreen made from vacuum-molded plastic provides uniform support for the siding and allows moisture to flow horizontally and diagonally in addition to vertically.
Image
A drainage plane is created behind lap siding by installing furring strips on the exterior walls over house wrap which is overlapped and taped at all seams to serve as an air and water barrier.
Image
A molded plastic drainage board rainscreen allows vertical drainage while providing uniform support for the siding and resisting compression from screws and nails.

Bees made a nest in the drainage plane behind a brick veneer wall by entering via unscreened weep holes
Image
Completed wall retrofit of masonry home (on right) showing new lap siding attached over four inches of rigid foam; windows were boxed with plywood to accommodate depth of foam plus 1x4 furring strips
Image
Fire barriers for ventilated wall cavities use thermally activated expansive materials to close off the ventilation space between the wall cladding and the sheathing during a fire while allowing air flow through the metal mesh during normal conditions
Image
Fire barriers for ventilated walls use heat activated intumescent expansive materials to close off the ventilation space between the wall cladding and the sheathing during a fire while allowing air flow through the metal mesh during normal conditions
Image
Ice dams formed by melting of snow on roofs can affect roofs, walls, ceilings, siding, and insulation.
Image
Kickout diverter flashing keeps bulk water from the roof from overflowing the gutter and continuously wetting the siding material.
Image
Moisture-resistant plastic and fiber cement exterior trim and cladding are indistinguishable from wood building elements.

Plan view of exterior masonry brick wall retrofitted with furring strips, three layers of rigid foam insulation staggered and taped at the seams, and 1x4 furring strips to provide a nailing surface and ventilation gap under lap siding
Image
Plan view of exterior masonry brick wall retrofitted with furring strips, three layers of rigid mineral wool insulation staggered and taped at the seams, and topped with metal hat channel providing a ventilation gap surface to nail under the lap siding
Image
Right - Brick veneer is installed with a 1-inch air space behind the brick, metal flashing and weep holes above and below the windows and at the base of the wall to direct out water that gets behind the brick.
Image
Right - Dovetail-shaped plastic mesh is installed to collect mortar droppings at the base of the wall to keep weep holes from being clogged.
Image
Right - Metal drip edge flashing is installed above hose bib and top of metal flashing is taped to wall.
Image
Right - The corrosion-resistant metal siding on this tiny house is fire resistant.
Image
Image
Right – Metal flashing is installed between the deck boards and house wall with the top of the flashing extending up behind the siding and the bottom of the flashing extending out and down over the ledger board
Image
Right: Flashing the butt joints in lap siding installations is a better practice than relying on caulk to seal the joints.
Image
Right: This vent was correctly flashed providing proper waterproofing detailing for this siding penetration.
Image
The combustible siding product on the left side in this demonstration burns readily when exposed to a burning wood sample, while the noncombustible siding on the right does not ignite
Image
This close-up of an exterior wall retrofit of a masonry brick home shows the fluid-applied water and air control layer (white), 2x4 furring strips and two layers of rigid foam insulation (pink), then 1x4 furring which provides a ventilation gap

This detailed decision tree can help homeowners and contractors make decisions about re-siding a home and upgrading windows
Image
This fastener schedule for metal panel siding shows denser spacing for the end panels to resist stronger wind pressures. Some manufacturers specify that panels be installed with the prevailing wind - in this example wind direction is right to left.
Image
This home has heat loss through the roof, leading to ice dam formation and structural issues during winter months.

Wrong - Gutters should be regularly cleaned or covered with screening to prevent accumulation of leaves, seeds, and woody debris, which can provide fuel for forest fires or nesting materials for animals.
Image
Image
Wrong - The gutter is missing kick-out flashing causing wall and window damage beneath it.
Image
Wrong - There is no step flashing along the base of the gable and the right window is missing sill trim.
Image
Wrong - Wall is missing step and kick-out flashing which has allowed water to rot the wood corner trim.
Image
Wrong - Water has gotten behind the paint, possibly due to lack of window flashing, leading to blistering.
Image
Wrong - When the lower break-away wall gave way in coastal flooding it peeled some of the EIFS siding off with it because there was no suitable break in the siding to allow it to detach cleanly.
Image
Wrong - Wiring holes are not sealed and possible missing flashing around windows is allowing water into walls and causing paint to peel.
Image
Wrong – The flashing of the roof-wall juncture was installed above the roof shingles instead of below the roof shingles; also no kickout flashing was installed.
Image
Wrong: The fiber-cement siding has cracked due to over-driven nails located too close to the edge of the board; these cracks provide a pathway for bulk water entry and offer little resistance to high winds.
Image
Wrong: The homeowner mistakenly filled in the weep holes in this brick wall with spray foam, preventing drainage from behind the wall
Image
Wrong: The waterproofing around this hose bib was haphazardly detailed allowing water a pathway to wick behind the siding.
