Shingling Over an Existing Roof

If your shingle roof is nearing its end of life and you are considering a new roof, you may have a more affordable option.

Your asphalt shingle roof represents an  opportunity to simply apply new shingling over your current materials, as long as a few conditions are present. If a new shingle roof is in your near future, you’ll want to read this blog.

Why Just Shingle Over Your New Roof?

The most compelling reason to apply new shingles over the old is to save money. You will avoid the cost of materials removal if you go this route. Also, ripping off old shingles can get quite messy, and clean up can be a project, so is an attractive option for many.

Finally, asphalt shingles have petroleum ingredients, and so need to be disposed of in a certain way – you cannot simply place them with your garbage pickup.

Is Your Roof a Candidate for a New Layer of Shingles?

Your roof is a good fit for simply adding shingles over the top of your current roofing materials if two facts are true:

• You only have one layer of shingles currently on your roof. It is not recommended to ever have more than two layers of shingles. So if there are already multiple layers, adding more shingles is not a good idea.
• You know that the underlying roofing structure is sound. One of the real drawbacks to shingling over current materials is that your roofing contractor cannot examine your roof deck and sheathing for any signs of deterioration. Therefore, if there is a water intrusion or mold problem, it will not be discovered during the re-roofing process.

Is it Smart to Make Your Roof a DIY Project?

Many people wonder if they can simply add new shingles to their roof on their own. Here are some thoughts to consider.

• As with any roofing project, you should never climb on top of a home unless you are knowledgeable about how to maneuver on a roof slope. Never climb up on a wet or slippery roof.
• Keep in mind that as well as safety issues, you may also void your roofing material warranties if the roof is not installed correctly.
• All roofing projects must be permitted correctly.

Shingling over Current Materials

• Make sure that your roof only has one layer of shingles.
• Remove roof caps and flashing.
• Repair any broken tiles on the original layer. If a tile is cracked, glue the piece down. IF a piece is missing, cut to size and repair.
• Install new flashing.
• Replace shingles by starting at the bottom. Begin with a starter strip and move upwards, nailing shingles just above tab cuts. You’ll need to work around vents and walls.
• Install counter flashing, reapply the ridge caps, and cut any excess shingling.
• You may wish to apply a seal or coating for UV protection and additional weather proofing.

When it comes time to re-roof your home, you have many decisions to make. If you have a shingle roof, you can remove the material and reinstall new asphalt shingles, choose to install a new tile or metal roof, or install new shingling on the old roof.
