Always research a roofing company before you allow them to do any work on your roof.

You want to call up the Better Business Bureau or visit their website to see if there are any complaints.

Ask for copies of the roofing company's liability coverage before letting them work on your roof.
If they are an experienced and professional company, then they should have these papers with them when they meet with you.

If you are trying to replace or repair a roof on your own, always take precautions.
Make sure to wear rubber soled shoes that grip and consider using a harness too. In addition, ask a buddy to remain on the ground in case you need help.

Always wear the appropriate footwear when venturing out onto your roof.
Wearing a rubber soled boot can help you to keep your grip and has been proven to limit the rate of falls experienced by roofers.

If you have a leaky roof, make sure that your gutters are clear.

If there is no way for water to drain, then the gutters can accumulate rainwater and cause leaks in the roof.

Tread lightly while you are on your roof looking for damage.
Prolonged exposure to water can lead to dry rot, which will compromise the integrity of your roof.

Make note of your initial impression of any companies you contact and receive quotes from.
How was the customer service? Did you have to wait long to speak to someone? Did they answer all of your questions thoroughly?
