Today's Homeowner looks at dozens of datapoints on roofers to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Cost is an important consideration when replacing a major piece of your home like your roof. Below, see the average price range for roof replacement on a 1,500 square foot home in Johnston, as well as price differences between different popular roofing materials.
A new roof installation is a major home renovation that can cost tens of thousands of dollars. It's essential to research and find a highly reviewed and recommended roofing company for the job. Here are some important considerations for choosing a roofer.
Though most homeowners don't think about their roof every day, it provides critical protections for your home. Keep watch for these common signs that your roof may need professional inspection and repair.
Your roof's age and material are key factors. Asphalt shingles, the most popular residential roofing material, generally last around 20–25 years before needing to be replaced. Schedule a professional inspection if your roof is approaching or past this lifespan to determine if it needs to be replaced.
Leaks are a clear sign that your roof requires repairs. Stains on insulation, ceilings, or walls, or in your attic often signal that water is getting through deteriorating shingles. Even small leaks should be taken care of promptly, as they can lead to mold and more harm over time.
If you can see the roof deck boards underneath your shingles, it means those shingles are severely curling or losing their seal and need replacement. Shingles should lie flat to keep water from getting into your home.
Check your roof shingles from the ground or a steady ladder. Look for tears in the shingle surface or loss of protective granule coating. Storms that bring strong winds can cause surface damage over time. To keep your roof in good shape, replace any shingles that are no longer securely attached or are openly gaping.
Roof flashing creates a barrier against the elements around vents, chimneys, valleys, and other areas that penetrate the roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Any issues with flashing should be addressed promptly.
If you notice your roofline displaying signs of sagging or uneven slopes, it could signal a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not properly supported or replaced.
The best type of roofing material for your home in Johnston will depend on things like your budget and how often you want to do maintenance.
Metal costs more but is more durable, while asphalt will be cheaper up front but will require more maintenance. Wood roofs have better insulation than many other materials, which can be very beneficial in the winter.
Contractors in Iowa must be registered with the Iowa Division of Labor if they earn more than $2,000 a year from their trade. All contractors must show proof of insurance, and contractors whose primary location is outside of the state of Iowa must be bonded.
It generally takes about one to five days to replace a roof. Factors that could influence the timeline include the accessibility of your roof, its size, and the weather in Johnston during the process. .
Your roof does impact the energy efficiency of your home. For example, in the winter a good roof allows you to spend less energy heating your home. Certain roofing materials, such as metal, provide better insulation than other types.
Usually, you need to clean your roof about once a year. You might need to do an extra cleaning if you notice buildup of moss, mold, leaves, or mildew.
