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 a major consideration when replacing your roof. Below is the average price range to replace a roof on a 1,500 square foot home in Alton. We also compare prices for popular roofing materials.
Installing a new roof is a big home renovation that might cost over ten thousand dollars total. It's crucial to research in depth to find a highly skilled and reputable roofing company for the job. Here are the main things to consider when hiring a roofer.
You may not think about your roof every single day, but it protects your home in important ways. Look out for these common signals that your roof needs to be checked and repaired by a professional roofer.
Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, normally last about 20 to 25 years before needing to be replaced. Schedule a professional inspection if your roof is approaching or past this lifespan to determine if full replacement is needed.
One of the clearest signs of a roof issue is leaking. Stains on insulation, walls, and ceilings — or in your attic — usually mean that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can encourage mold growth and roof damage.
If you can see roof decking or sheathing underneath your shingles, it means those shingles are curling substantially or losing their seal, and replacement is required. Shingles should lie flat to keep water from leaking into your home.
Inspect your shingles closely from a steady 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 good condition, replace any shingles that are no longer attached or have gaping holes.
Metal flashing on your roof seals off valleys, chimneys, vents, and other areas where water can leak in. If the flashing is becoming damaged, loose, or worn down, it may leak. Promptly address any flashing issues.
If your roof sags or is uneven, schedule a professional inspection. These issues could signal a structural problem. A sagging roof that's not properly supported or fixed will continue worsening over time.
The best type of roofing material for your home in Alton will depend on several factors, including your budget and how often you're willing to do maintenance.
Asphalt is less costly, while options like metal cost more but last longer. You also might choose a material like wood for its environmentally friendly nature.
Roofing contractors in Illinois must obtain a license from the Department of Professional Regulation. Contractors must be both bonded and insured to apply. There are licenses for residential work, both residential and commercial/industrial work or for commercial and industrial work only.
Generally, it takes around one to five days to replace a roof. Factors that could influence this timeline include the accessibility of your roof, its size, and the weather in Alton during the process. .
The best time of year for a roof replacement is spring or fall. If you start your roofing job in the summer, warm weather in Alton can slow down work.
The best roofing color for you depends on several factors like the color and style of your house and the local climate. For instance, if you have a Spanish style home, then you'll most likely want a terracotta roof. Also, those in a hot climate may want to avoid darker colors since they absorb heat, which makes cooling your home more difficult.
