When it’s time for a new roof you have a couple options to pick from, you can either remove the old roof or replace it with a new one. You can also build over your existing roof. When trying to decide between the two there are a few options to think about, such as your budget and the condition of your current roof. There are some things to check for when choosing your style of roofing installation.

• Asphalt shingles. If you have them, you will need to remove them since you cannot mix materials.
• Two layers of Shingles. Adding a third layer would cause your roof to be too heavy which could cause damage in the future.
• Your old shingles are curling. Your shingles can begin to curl over time or with too much heat. Roofing requires a flat surface so the curled shingles will need to be removed.
• Visible damage. If you have visible damage, such as mold or rot, you will need to remove it instead of roofing over it. Covering the damage would just cause more problems in the future.
