What Comes With A Complete Roof Replacement

roofing_contractors_apple_valley_mnIf you live in your house for a very long time, there is a good chance that you will need to eventually replace the roof. Even a well-maintained, properly-installed roof will provide you with years of protection and use but will eventually reach the end of its useful life.

If it is time for your house to have a new roof, it is useful to know all that is involved in a complete roof replacement – and there is more involved than just replacing the shingles.

Tear shingles off – You can learn a lot about the overall condition of a roof by what shape its shingles are in. Worn, cracked, or curled shingles might be a sign that the roof needs to be replaced. If so, then you might need to tear the old shingles off, or in certain situation, your roofing contractor might think it is a good idea to add a new shingles layer over the current layer.

A full replacement -starting from the bottom up – involves tearing the old shingles off down to the wood decking on the roof.

The roof decking – The roofer will inspect the wood deck on the roof to see if it is in need of repair, or if it is deteriorated past the point where it needs to be replaced. The wood deck is the base of the roofing structure and helps to ensure that the shingles stay in place.

The underlayment – With a full roof replacement, the underlayment is replaced. It is the waterproof or water-resistant barrier that is directly installed to the deck of a roof. One common underlayment material that is used is roofing felt and its protective material is asphalt.

Apply new flashing – That are certain parts of a roof that are especially prone to water damage and leaks, including the perimeters of skylights and chimneys, roof valleys, and any place where there is heavy water runoff. Flashing, which is frequently made out of rust-resistant metal, offers added protection in areas where there are two opposing surfaces that meet or where there is any heavy runoff.

Ice dam protection and drip edging – A new roof also involves new metal drip edging being installed around the edges of the roof, including the two eave sides. If you live in an area where cold weather may cause ice to accumulate on your roof, it is also recommended that you add an ice and water barrier layer. A waterproof material layer can be installed to prevent any melting ice from getting underneath your shingles.
