According to the National Weather Service, the average high temperature goes over 70 degrees Fahrenheit between May and October. The average low doesn’t go far from 50 degrees. With this range of temperatures, roofs endure a high amount of heat. Over time, the materials can reach their limits.
Your home’s roofing is its primary defense against the elements, so if you’re in need of roof repair, replacement, or any other services, it is important that you work only with an excellent roofing contractor. Here are some pointers on what you should look for in such a contractor.
Skills and Experience
First off, you must be sure that they can provide you with the services your roof needs. WiseGeek explains that roofing contractors generally perform roof repairs and replacement, but many companies extend their services beyond that. Some, such as Shelton Roofing, venture into emergency roof repair, gutter work, and even energy-efficient roofing.
Once you know that a contractor can provide your roofing needs, you can then inquire about their experience. For instance, contractors that have been in business for decades could only have lasted that long by consistently providing high quality service. In addition, it may help to check out their website for reviews, and find out what their customers have to say about their service.
You can also ask for certifications. For example, Diamond Certified is a reliable indicator. This certification body surveys a large randomized sample of companies’ actual customers to get an accurate representation of each company’s customer satisfaction level. The certification is only awarded to businesses who get a score higher than 90 (on a scale of 1-100). You can also look for certifications granted by prestigious roofing manufacturers to qualified contractors.
Ask About Safety
By nature, roofing work can be dangerous, so it’s important for you to know a contractor’s safety measures. Ask what protocols they have in place, as well as the equipment they use when working on projects. You should also remember the importance of insurance. Without one, you may be liable for any injury that could happen in your property while the roofing work is ongoing. You must make sure the contractor has workman’s compensation insurance to protect yourself and your property in case of an accident.
