If you’re investing in a new roof this season, make sure to cover all the bases involved with the project. This means making careful decisions on what seems–at first–like a simple thing. You should, for instance, consider whether you should go for closed or open roof valleys. But what’s the difference between the two? Cantrell Roofing, expert in roof repair and replacement in the area, discusses them in detail.
What’s a Roof Valley?
A valley refers to the spot where two roof planes intersect, and is probably one of the most vulnerable areas of a roofing system. When not installed properly, the roof valley allows rainwater to seep through the roof until it eventually finds its way inside your home. Completing the valley of your new roof involves two methods: closed and open.
Closed Roof Valley
As they work on your roof replacement, your roofing contractor will install the underlayment, which may be a self-adhering water and ice shield that serves as the valley lining. If you chose a closed roof valley, your roofer will install the shingles onto the roof deck and extend them through the valley area, completely closing it in. This method is more preferred by homeowners because:
- A closed valley won’t require additional materials, making it more cost-effective.
- It is easier and faster to install compared to an open valley.
- The valley is covered by shingles, which makes it better from an aesthetic standpoint.
Open Roof Valley
Unlike a closed valley, this method involves installing a sheet of metal after the self-adhering underlayment. The roofer will then install the shingles over the roof deck, but they will not run through the valley area. Instead, the material is cut out of the valley area, leaving it open. You might like an open roof valley because:
- It sheds ice and water more quickly than a closed valley.
- This method helps minimize granule loss in your shingles, allowing for a longer-lasting roof.
- It makes solving roofing issues, such as leaks, easier down the road.
