One of the most essential needs in life is a roof above your head. Thus why the quality of your roof is of the utmost importance. If you don’t invest in a good roof, it could lead to leaking, damage, sinking, clogged gutters, and exposure to the elements. But a roof doesn’t just consist of shingles – in fact, there are many layers that go into making the roof to your home your shield from the outdoors.
Understanding how your roof functions and the layers that go into it will not only give you a new appreciation for your roof, but will also demonstrate the need for prioritizing the quality and health of your roof.
1. Roof Decking
The very first layer, essentially the skeleton of your roof, is the roof decking, also known as roof sheathing. The decking usually consists of wooden panels or planks that lay out the general structure of where your roof will be on top of your house. These are important as a base layer and should be strong, dry, and protected. If moisture gets trapped under the other layers, it could lead to this layer rotting, which cannot be fixed unless the old roof is torn up. The paneling should be strong since it will be supporting all the other layers.
2. Drip Edge
The next layer should be the drip edge, which is vital for redirecting water away from the moisture-susceptible layers. Drip edges are thin, flexible pieces usually made of metal that hang over the edge of the roof. They protect the roof decking from moisture, as well as the fascia, which is the horizontal paneling that the gutter sits on. If a drip edge is not installed, or is not functioning properly, this leads to rotting and water damage.
3. Ice and Water Shield
Similar to the drip edge, the ice and water shield is essential for protecting against more intensive elements. These are waterproof sheets that should be nestled in corners of your roof, valleys, and around penetrations in order to provide the best defense against moisture. These also help protect your roof decking. Ice and water shields are important roof layers in states, like Idaho, that can get snowy winters.
4. Roof Underlayment
This layer serves as an in-between layer, sitting between the roof decking and the outermost shingles. It is made of either felt or a synthetic material and serves as the last kind of protection for your roof decking if any moisture gets under the shingles. Because of this, investing in good quality underlayment can make the difference in your roof’s life.
5. Starter Shingles
Though the roof is almost ready for the full installation of shingles, starter shingles must go on first. This is a small sheet of precut paneling in a row that has adhesive on it. This is laid down in order to make a sealed edge at the eaves, or edges, of your roof. This layer can help with keeping the roof in place during strong winds.
6. Shingles
The most visible part of the roof, the shingles are just as important as any other layer of your roof. Depending on what you want, they can be made from a variety of roofing materials, like asphalt shingles, metal, cedar shake, synthetic, and concrete. At Premier Roofing and Restorations, we are happy to help you determine the best material for your home.
7. Roof Flashing
Alongside your shingles, roof flashing should be installed. It serves as another protectant, consisting of metal sheets that deflect water away from important areas, like windows, chimneys, walls, and roof valleys. Since they are made of metal, they are meant to last and can even outlive your roof if well-taken care of. They should be inspected regularly to ensure that there is no leakage.
8. Ridge Capping
Ridge capping is the layer of shingles that lay along the seams of two slopes of roofing, closing up any gaps in between the shingles. They tend to be a thicker material that is pre-bent, for easier application. Though this trim can help with aesthetics, the quality of the ridge capping is important for your roof – if the wrong material or thin shingles are applied as the capping, it could lead to more costs and damage down the road. It’s important to use the manufacturer’s ridge capping accessory so that it is properly installed.
9. Roof Vents
After all of the layers of roofing is put on your house, a roof vent provides ventilation to maintain the health and longevity of your roof. The airflow that it causes keeps your attic and roof able to breathe. Depending on your needs, you may need to have either a passive or active vent installed.
