Measure twice, cut once. If you will be doing your own roofing job, you want to make sure your measurements are correct. This will save you both time and money. You can assure your measurements are accurate by taking the extra time it takes to measure two, or even three times.

Before you hire a roofer, ask whether he will be using a subcontractor to complete some of the work. If so, request the same types of documentation as you would for the roofer. Ask for the subcontractor's references, workers' comp insurance and proof of liability coverage. It is not enough for just the roofing company to have these items.
The contractor that you hire to do your job should be local and reputable. Many people hire people from out of town because they are a bit cheaper, but that poses a problem if you have any issues. The contractor may not be able to come out and fix your problems right away since you are so far.
As a general rule, be generous in estimating the extent of damage when you do roof repairs. Don't just replace the shingles that are obviously damaged. Swap out the ones around them, too. If you have to patch the roof deck, make the patch much larger than the damaged area. (Or replace the entire sheet of decking.) It's better to buy a few more materials than to do a repair job that doesn't fix the whole problem.
When you are looking for a good roofer to handle any roofing issues you may have, you should ask your friends, family and neighbors for referrals. If you know someone who has had work done on their roof, they are likely to let you know how good their roofers were, which could end up saving you a lot of time and money.
You should now be aware of what makes a decent contractor and what makes a shady dealer. Apply these constraints to your local options and narrow down the choice to only a few remaining contractors. Call each of these possibilities independently and make your final decision when face-to-face. This is the formula for finding the best contractor for the job!
