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:
Budgeting is important when tackling a project as big as replacing your roof. Below, we provide the average price range for replacing a roof on a 1,500 square foot home in Thornton. We also outline price differences between common roof materials.
A new roof installation is a major home renovation that can run over twenty thousand dollars total. It's essential to research and find a top-rated, trusted roofing company for the job. Here are some important considerations for selecting a roofer.
Though most homeowners don't think about their roof on a daily basis, it provides critical protections for your home. Be attentive for these common signs that your roof may need inspection and repairs from a professional roofer.
Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, typically last around 20–25 years before needing to be replaced. Have your roof evaluated if it’s approaching or past this lifespan to determine if it needs to be replaced.
One of the most obvious signs of roof trouble is water leaks. Stains on your ceilings, walls, or insulation, or in your attic are often a sign of water seeping through worn or damaged shingles. Even small leaks should be fixed promptly, as they can facilitate mold growth and further deteriorate your roof.
If you can see the roof deck boards underneath your shingles, it means those shingles are severely curling or losing their seal and need to be replaced. Shingles should lie flat to keep water from getting into your home.
Examine your shingles closely from a sturdy ladder or while on the ground. Look for shingles that show cracks or no longer have their protective granule layer. Storms can cause roof damage over time. To keep your roof in working order, replace any shingles that have become detached or have gaping holes.
Roof flashing provides a watertight seal around valleys, chimneys, vents, and other areas where water can penetrate your roof. Peeling, cracked, or deteriorated flashing can allow leaks. We recommend quickly addressing any problems with the roof flashing that come up.
If you notice your roofline showing signs of sagging or unevenness, it could signal a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not given proper reinforcement or replaced entirely.
The best type of roofing material for your home in Thornton will depend on several factors, including your budget and how often you want to do maintenance.
Asphalt is less costly, while options like metal cost more but last longer. Clay roofing may be beneficial around Thornton due to its high solar reflectivity. Roofs of this type can help you save on cooling costs during the sunny summer months. You also might choose a material like wood for its environmentally friendly nature.
In Colorado, roofing contractors are not required to hold any specific contractor license. However, all businesses must hold a valid business license.
Roof replacement normally takes between one and five days. This timeline may be influenced by factors like the weather in Thornton, the accessibility of your roof, and its size. .
The best time of year for a roof replacement is fall or spring. If you start your roofing job in the summer, warm weather in Thornton can slow down work.
Generally, you should clean your roof about once a year. You may want to clean your roof more frequently if there's a buildup of mold, mildew, leaves, or moss.
