There's no doubt that re-roofing can have its advantages. For example, when a homeowner chooses to re-roof rather than strip and replace their entire roof, they will be able to save both time and money. Removing old roofing materials requires additional time, and the labor involved will increase the cost of the new roof. Additionally, by placing the new roof over the existing roof, the risk of water damage from having the roof exposed and unprotected can be minimized.

Of course, there are some things that Urbana roofers will look for before agreeing to take on a re-roofing job. The roof should be stripped and the new roof installed if there are already two layers of shingles in place. Depending on the slope of the roof, it is possible that a re-roofing can take place only over a single layer of asphalt shingles. Generally, a roof will need to have a pitch of 5:12 or steeper in order to be able to install a third layer of shingles.

The next thing a roofer will look at is the condition of the existing roof.

If the sheathing is in good condition and the existing shingles are not badly curled or damaged, re-roofing might be a good choice, especially when a homeowner wants to save on roofing costs. However, it's important to keep in mind that the savings a homeowner will have are only temporary. The next time the roof needs replacing, additional work and expense will be required in order to remove the multiple layers of shingles.

If there are shingles that are starting to curl, these will need to be clipped in order to provide a good base for the new roof. In prepping the roof for the new installation, roofing scraps can be used as shims to replace curled or damaged tabs. Rakes and eaves will need to have a new drip edge installed so that the exposed roof edge is properly protected.

Choosing a heavy shingle for the re-roofing can help prevent telegraphing of irregularities from the existing roof. Shingles that are laminated or heavily textured often make a great choice. When re-roofing with asphalt shingles, it is important to use galvanized roofing nails that will be long enough to penetrate the underlying sheathing. Care should be taken to ensure that new rows of shingles are nested below existing rows, so the new nails are spaced far enough away from existing nails to prevent splitting the sheathing.
