Roofs generally last from 15 to 30 years. The period could vary based on the type of material used, exposure to weather extremities, and quality of roofing. If you are a first-time homeowner, you should know some points beforehand to select your contractor who can do the repair and replacement well. A good contractor is key, as a bad job can cause more damage to the roof quickly and require frequent and expensive repairs.

When is it time to replace the roof?
The most visible and tangible sign that your roof needs repair is water leakage. Other signs that you should watch out for are

• Sagging roof
• Cracked or damaged shingles
• Mold in the house
• Growth of moss and other algae
• The last replacement was at least 25 years earlier.
• A sudden spike in energy bills

If your answer is affirmative to any of the points, you can get ready to repair or replace the roof based on its current condition.

1. When to start work
Unless it is an emergency, and if you have time to plan, fall is considered the best time to start your roof replacement. So start making plans accordingly.

2. Things to do before hiring a contractor
One big advantage of replacing a roof is that you can replace it with modern material. Metal, clay, concrete, ceramic, and tensile roofing are stronger and durable. You should also inquire if you want the old roof removed or new shingles placed over the old one. The decision can be based on the quality of the roof and the condition of the existing wood. Understand the contractor’s plan for disposal of the removed roof.

3. Get quotes from many contractors
Research online for experienced and highly rated contractors. You should talk to friends and family who have recently replaced or repaired roofs. Both these acts will help you gain more knowledge, tips, and tricks, and new ideas to get the job done. There is nothing like a first-hand recommendation to get a good contractor for quality work. Never compromise on quality in favor of reduced cost, as it can lead to a botched-up work. Read the contract multiple times to understand the fine print, hidden charges, and terms, and if the contractor abides by rules that govern your city or town.

4. Prepared to stay away during the replacement
Replacing the roof is noisy work and can be distracting. You should be prepared to stay away for a few days if you have very young kids or older people at home. Too much movement and noise can disrupt your neighbors. Look for an experienced contractor who can work with as little disruption to your and your neighbors’ peace and who works within the stipulated working hours, completing the work as per the contract.
