A roof constructed of asphalt shingles lasts about 20 years on average before leaks develop. In some cases, patching can fix a leak, but water getting into the home is a sign that the need for roof replacement is imminent. Contractors providing residential roofing installation in Oshkosh, WI, strongly encourage homeowners to replace the shingles instead of adding a second layer on top. Adding that second layer is known as reroofing.

The only reason homeowners should choose the reroofing choice is if they truly cannot afford the cost of shingle removal and replacement. They must start planning financially for the full project of residential roofing installation in Oshkosh, WI, since that will become necessary within 10 or 12 years. Reroofing cannot be done more than once, as three sets of shingles are too heavy.

Longevity

Two sets of shingles are not better than one when the second set covers an old, leaky roof. A completely new roof installed after old shingles are removed typically lasts about twice as long.

Aesthetics

A single layer of shingles also looks better. It can be difficult for roofing contractors to make the second set sit evenly on top of old shingles that may have some warping or buckling issues.

Resale

In addition, if the homeowners are planning to sell the house after seven or eight years, some potential buyers might shy away from the purchase. They realize they would have the expense of a new roof shortly. Skilled residential roof installation is provided by Motto and Sons Construction.
