Reasons why Re-roofing is not suggested!

1) Difficulty with uneven surfaces
Shingles works on flat, level surfaces. When shingles are forced to be installed on uneven or patchy foundations, the old flaps can teleport to the new layer, making the top layer more difficult to secure. This will almost certainly cause problems later, as it becomes more difficult to install the shingles correctly and accurately.
2) Improper inspection
Old shingles prevent contractors from properly inspecting the condition of the existing roof. While reroofing is still a possibility for homeowners, the presence of an “old” roof prevents roofers from properly inspecting the deck to see if the plywood is damaged and needs to be repaired first. Without starting from the base, the contractor cannot determine whether your home has a proper foundation before starting the project, which can result in costly future repairs.

3) Expensive
Covering can be more expensive than replacement in the long run. Saving a thousand dollars through a simple roof renovation might sound tempting, but the costs associated with later replacements due to poor foundations certainly won’t.

Removing old shingles and replacing them with new layers is almost always more sustainable for years to come. Also, every roof gets replaced eventually: by replacing a new roof instead of completely replacing it, you’re just delaying the inevitable disposal costs, not stopping it.

4) Insufficient installation of water leakage
Covering shingles will prevent roofers from properly installing water and ice leak barriers. If you live in an area with severe winters or other environmental concerns, water barriers are essential because they ensure ice doesn’t leak out from under old shingles.

5) Weight loading
Small roofs can’t handle huge weights. Adding a second layer to your roof will only increase the pressure and potentially cause more roof problems, especially if you live in an area that gets a lot of snow every year.

Even for mid-sized homes, adding another roof weight can create many problems once winter arrives.

6) Warranty issues
Re-roofing may affect the warranty on new shingles. It is always advisable to check the requirements and any warranty issues with the manufacturer before doing any roof installation to avoid any misunderstandings later.

7) Building Code
Certain geographic areas have guidelines on how many roof layers a building is allowed to use. While some building codes allow re-roofing, others may only allow one layer of shingles. If you live in an area experiencing severe storms, be sure to check local regulations.

8) Future relocation plan
Roof repairs may reduce the value of your home and make it harder to sell if you plan to move in the near future. While roof repairs won’t affect existing homeowners, new homeowners will be forced to tear off two coats of shingles later. For this reason, many home inspectors report double roofs and educate interested buyers about the problems that come with roof renovations.

If you’re still struggling between reroofing and roof replacement, you’ll want to consult a professional roofer to find out which route is best for your home.
