Roofing FAQ’s


At Porter Roofing, we want to share our roofing knowledge. Here are answers to some of the most common roofing questions, along with important resources for every roofing consumer.

Frequently Asked Questions

  • Before you make a decision to hire a roofing contractor, we recommend that you get quotes from three roofing companies. The three quotes may vary significantly in detail and pricing, so read them carefully and ask about anything you don't understand.
  • Next, ask each roofing contractor for referrals from homeowners or building owners with similar projects. Ask the referrals about their experiences with the company they chose, why they chose them, and what they learned from the process.
  • Before roofing contractors arrive each day, move all vehicles from your driveway and the street in front of your house. The roofing contractors bring equipment and work vehicles that need to be close to your home or building.
  • Roofers need electricity for some tools. Check with your roofing company to see if they need access to electricity.
  • In some instances, it is possible to install a new layer of shingles over the existing shingles. However, you can't always add another shingle layer. If your roof already has more than one shingle layer, most likely, you will require a new roof installation. A professional roofing company can evaluate your current roof and let you know if recovering is an option.
  • Any time someone on your property gets hurt, even people you hire to work on your property, they can sue you. When you hire a roofing company that carries insurance, the roofing company insurance covers their employees in case of a worksite accident.
  • Your new roof life expectancy depends on the roofing material, the climate, and the installation. In general, an expertly installed and maintained roof should last 25 years, though some materials, like natural stone, can last longer.
  • Always ask your roofing company about the warranties they offer for roof workmanship and the warranties offered by the roofing material manufacturer.
  • In many cases, you can replace roof tiles or shingles without a full roof replacement. As soon as you notice tiles or shingles from your roof in your yard, call your roofing company for an inspection. Don't inspect the roof yourself. A professional roofing inspector knows how to walk on your roof without causing additional damage and can spot minor signs of roof damage that you would miss. Often, you can repair minor problems easily and inexpensively. However, if you don't repair them, they can cause damage to your walls or further damage to your roof, resulting in higher repair costs.
  • If you would like to perform a checkup on your roof yourself, please review the Roof Checkup Guide for Homeowners from the National Roofing Contractors Association.
