Asphalt shingle roofing is the most popular type of roofing because it is relatively inexpensive and easy to install. Metal roofing is more expensive than asphalt shingles, but it is also more durable and can last for many years. Tile roofing is the most expensive type of roofing, but it is also the most durable and can last for centuries. Another roof type is slate roofing, which is a premium roof system made primarily out of natural slate tiles. The most inexpensive is roll roofing, which works well for utilitarian structures such as sheds, shops, barns, garages, and most types of outbuildings. Wood roofing is perhaps the oldest type used. It is a very good insulating material, but is high-maintenance and also flammable. Other roof materials involved include flashing, sheathing, roofing paper, roofing felt, tar, and nails.

Is it common for ridge vents to leak?
It is common for older style metal ridge vents to leak. Metal ridge vents require more face screws or face nails causing them to be more susceptible to leaks through fasteners securing them to the roof. Also old metal ridge vent are narrow, barely covering the opening created for hot air to escape from the attic, usually 4 in for the ridge cut, the old style metal ridge vents are only 5 in or 6 in wide. Modern ridge vents are plastic with shingles over the top and when properly installed should not leak.
What keeps ridge vents from leaking?
Modern ridge vents consist of a 4-foot plastic ridge vent which is then covered by shingles. The roof opening that is cut in a ridge is 4 inches wide for hot air to escape.

Inspect the valleys to check for signs of wear or improper installation, and to confirm shingles aren’t getting crushed or broken by foot traffic in the valley. If any of these are present it might be necessary to replace the valley.
If valley replacement is necessary, remove everything around the surrounding the valley, install an ice and water barrier on the roof decking. Install the shingles with one of 3 options, a california cut, an open metal valley, or woven valley.
What causes roof valleys to leak?
Roof valleys can leak due to several reasons which include:
- Incorrect nailing (nails too close to the valley)
- Improper installation of underlayment or ice and water shield in valleys
- Damaged shingles surrounding the valley
- Nails popping thorough shingles near a valley
- Excessive foot traffic of shingle breakage

After rough holes are cut, the sun tunnel section is assembled and lowered down through the flashing, and tapped after confirming the tunnel section requires no further adjustments.
The dome is then installed and secured on top of the sun tunnel. The sun tunnel is then secured to the ceiling ring. Finally, the diffuser and trim ring is installed to cover the tunnel itself from the inside.
