It's a busy season for building custom homes in Iowa. Unfortunately, many of these new, beautiful homes have flawed roof plans. They may look incredible, but without the proper design, roofs are susceptible to damage, which could cost homeowners thousands of dollars to repair. If you're buidling a new home in the Ankeny, Huxley, or Des Moines area or considering installing a new roof on your current home, consider the following factors very carefully.
There are two ways to apply shingles to a roof. One way is to lay new shingles on top of old (existing) shingles. The other way is to first tear off the existing shingles, and then lay down the new ones. While the first option is less expensive, it could cause major problems down the road. Your initial thought may be that layering shingles will offer your home additional protection. The truth is, however, that there are many reasons that layering shingles this way is considered bad practice.
Disadvantages to laying new shingles on top of old ones:
Advantages of tearing off old shingles first and then laying down new ones:
A proper ventilation system should be installed beneath the roof deck. This will reduce the buildup of heat, moisture, and condensation in your attic, as well as prevent snow and rain infiltration and ice dam buildup. A good ventilation system keeps the attic temperature closer to the outside temperature by creating a continuous and balanced flow of air, removing humidity and drawing in cool, dry air.
Make sure your roofing contractor considers how water flows off of a roof during heavy rains. If this is not considered thoroughly in the initial design and installation stages, your roof could be susceptible to water intrusion, costing thousands of dollars in damage to the interior of a brand new home.
By installing underlayment, you are giving your roof an extra layer of protection. It will be placed between the wood decking and shingles. This protects your home against heavy or wind-driven rains and ice dams.
Installing a new roof is a big investment. Don’t cut corners just to save a little money now when you may regret it later. Take a good look at your options and carefully consider what is best for your home, both now and years down the road.
