"We had a roof that needed cap shingle replacement prior to the sale of the home due to degradation of the previous shingles of the wrong type. Weather Pro Exteriors had someone out quickly to provide an estimate and they were able to schedule the repair within a week. The customer service was excellent and they were easy to work with. Pricing was significantly lower than another quote I received and we are happy with the work performed. Very personable and responsive!"

"We hadTechos do a metal roof on our lake house. We live in Texas and so we were worried that the long distance communication to get this done would be challenging. Jose did a great job staying on top of all aspects for the project, from electronically signing the contract, to choosing the right material. They finished the job on the day they promised and the house looks amazing. Could not be happier with how it turned out. Definitely recommend these guys to anyone interested in a metal roof."

"Erik Pfarrer was our salesman and he was AWESOME!!!! Explained everything and went above and beyond I even expected him to do. Awesome person. Erik Alvarez The foreman on the job was wonderful too went above and beyond to help to make everything perfect. Any question I had was not pushed aside. It was addressed immediately and explained in detail. Everyone working on my house, roof, sightings, and gutters were professional and cleaned up wonderfully after they were done, including the guys who did the roof. They even cleaned off the top of the roof to make it look even better than it did. Would definitely recommend."

FAQs for asphalt shingle roofing installation and replacement projects in Janesville, WI

Roofing professionals can usually install a medium-sized asphalt shingle roof in two to three days. Installation time increases if your roof is particularly steep or difficult to access or has features like chimneys or skylights that roofers must work around.

Three-tab asphalt shingles usually have the lowest upfront cost of any roofing shingle material. They’re sturdy and typically last 15 to 20 years. However, they may have a shorter lifespan in especially hot or cold climates. Talk to a local roofing professional about the best materials for your climate. In some cases, materials with a higher upfront cost may save you more on repairs or replacements in the long run.

Start by multiplying the length by the width of your roof to calculate the square footage. Most shingle replacement costs $4 to $12 per square foot for materials and labor, depending on factors like the material and the slope of your roof. Once you know the size of your roof, you can calculate a rough estimate of total costs or contact a local roofing professional to provide you with a custom quote.

Asphalt shingles are generally considered to be a low-maintenance item. However, cleaning your asphalt roofing can help prolong the lifespan and keep it looking fresh. If you’re comfortable with DIY and have the proper equipment, you may be able to clean your asphalt shingles yourself. However, if you have an especially high or steep roof, it’s usually safer to hire a professional roof cleaner.
