Though shingles could be the cause of leaks, take a look at your roof's foundation. If your home has dry rot in the outside walls, water can enter there. Check all entry points to make sure this doesn't happen.
It is crucial that you make repairs right the first time. This often means searching for other leaks after the initial spot has been fixed. Look at the whole roof and you might see that several areas are causing the leak.
If you're going to have to get onto the roof to do some repairs, put on rubber boots. You need rubber soles to get good traction even when it is dry and sunny. You never know what you will encounter on the roof, and what you will have to do, so good footwear is essential.
Before signing a contract with a roofing contractor, there are many questions you need to ask him. For instance, you should inquire as to how many nails will be used for each shingle. Most of the time, more than three nails is going to be required for a good job. Ask detailed questions regarding their methodology and ensure you are satisfied with their responses. If they don't answer things right, move on.
When you pick a roofer, make sure they carry liability insurance. This is a good sign of the reliability of the contractor. This will also assure that should something happen during the roofing process, their insurance will cover it.
It's best to use a roofing contractor who has extensive experience in the industry. Ask your friends and family for recommendations if you know they have hired someone in the past. This will ensure that you get a professional experience.
When hiring a contractor, ensure he has the proper licenses. If you are not sure what is required in your area, do not just take the roofer's word for it. Call up the local building department and ask what you will need.
