If you live in a home for a long time, chances are you’ll need to replace the roof eventually. Even a properly-installed, well-maintained roof will provide years of use and protection but will reach the end of the lifespan.
If it’s time for a new roof on your home, it’s helpful to know everything a complete roof replacement entails – and it involves much more than simply replacing shingles.
1. Tearing off shingles
You can tell a lot about a roof’s overall condition by the well-being of its shingles. Curled, cracked, or worn shingles may signal a need for a roof replacement. If so, you may need to tear off the old shingles or, in some cases, your roofing contractor may think it wise to put a new layer of shingles over the existing layer.
But a full replacement – from the bottom-up – means tearing off shingles right down to the roof’s wood decking.
2. The roof’s decking
Your roofer will inspect your roof’s wood deck to see if it needs repair, or whether it’s deteriorated to a point where a replacement is necessary. The wood deck serves as the base for your roofing structure and ensures your shingles remain intact.
3. The underlayment
A full roof replacement also means replacing the underlayment, which is the water-resistant or waterproof barrier installed directly to a roof’s deck. Roofing felt is a common underlayment material and uses asphalt as its protective material.
4. Apply new flashing
Some parts of the roof are particularly prone to leaks and water damage, including roof valleys, chimney and skylight perimeters, or wherever water runoff is heavy. Flashing, often made of rust-resistant metal, provides extra protection for those areas of heavy runoff or where two opposing surfaces meet.
5. Drip edging and ice dam protection
A new roof also means installing new metal drip edging around the edge of the roof, including on both of the eave sides. Meanwhile, if you live in a region where bad weather can cause ice accumulation on your roof, a water and ice barrier layer is also recommended. A layer of waterproof material is installed to prevent melting ice from backing up under your shingles.
