San Antonio Roofing: Article About The Pros and Cons Of Reroofing
When it's time for a new roof, homeowners have the option of recovering the old roof instead of tearing off the old roof and replacing it. Recovering a roof adds a new layer of shingles. The process is generally much faster, less expensive and more convenient than completely replacing a roof. However, homeowners must use the same type of roofing material in both layers, and the roof will still need to be replaced eventually. Hiring an experienced, trusted San Antonio roofing professional to inspect the home or business can help homeowners decide if reroofing is the right choice. Homeowners are first encouraged to consider the pros and cons of reroofing.
Reroofing can save homeowners over $1,000. It's an economical way to improve the look of a home and to extend the lifespan of an existing roof. A new layer of shingles should last only about 10 years, however, compared to 20 to 30 year lifespan of an entirely new roof.
There are also some downsides to reroofing. The old shingles should be in relatively good condition before a reroofing procedure takes place. A new layer of shingles won't sit on the roof correctly if the shingles underneath are too badly cracked or warped, and these structural deficiencies invite wind or water damage. Additionally, two layers of shingles trap more heat, which could increase air conditioning costs in summer.

If the roof has algae or mold, it will keep growing after the new shingles are added, and the roof will have to be replaced eventually. When a roof needs replacement after being recovered, two layers of roofing materials must be removed, which will make the future replacement project longer and more labor intensive.
In many cases, completely replacing a roof is a better option. If a home already has more than one layer of shingles and the top layer looks worn, it's time for a new roof. A new roof is also needed if parts of the roof deck are damaged, if homeowners suspect damage or if the decking can't support two layers of material. Tile and slate roofs can never be recovered, since the roof materials involved are too heavy. Unfortunately, tearing off an old roof can be noisy and messy. A dumpster or trash receptacle must be delivered to the site to hold the old materials, and they have to be taken to a landfill or recycling center when the project is over. Homeowners might not have access to areas like the garage while the old roof is being removed.
