When the time comes that a new home roof is needed, some contractors offer both standard roofing replacement and re-roofing.
Re-roofing is said to save money on roofing services and it can; however, the choice to re-roof in lieu of putting on a totally new roofing system should be made carefully.
Before hiring a roofing contractor for a re-roof, homeowners should be aware of both the pros and cons of this practice in order to make an informed decision.
What Is Re-Roofing?
Re-roofing is a method of applying new exterior materials over older ones in lieu of roofing replacement to save money on the installation.
It usually involves putting a new layer of asphalt shingles over an existing layer, but sometimes can mean applying metal panels over asphalt shingles.
This technique can be used by roofing contractors in certain circumstances to cover up old shingles or minor damage but is not recommended as a patch over major damage.
What Are The Advantages of Re-Roofing Versus Roofing Replacement?
When carefully done by professional roofing services, re-roofing can offer a few advantages for homeowners looking to save some money on their new roof system:
- Lower Cost - Since adding a new layer does not involve tearing off the old roof first, it requires much less labor. The cost involves only that of applying new shingles and the time required to do it.
- Faster - Re-roofing can be accomplished in half the time or less than a total roofing replacement, once again because it involves only laying on a new layer, not tearing off the old materials first.
- Less Mess - With no tear-off involved, there is no mess nor a need to bring a dumpster to the property for taking waste materials away.
What Are The Disadvantages of Re-Roofing?
Though re-roofing involves a considerable cost saving over having a full replacement done, there are a number of disadvantages to the process that homeowners should know about:
- Not All Roofs Qualify - Re-roofing can only be done if there is only one layer of shingles already on the home and no other damage beneath the shingles that must be repaired. Local building codes usually prohibit roofing contractors from installing more than two layers of materials on any house and if there is damage that must be repaired, that will involve tearing off the old materials.
- Re-roofing Adds Weight - Another layer of shingles installed by roofing services can nearly double the weight of the roof. Some homes may not be structurally able to bear that additional weight.
- Repairs Are Harder to Make - With two layers of materials on a roof, any needed repairs that can happen over time will be more time and labor-intensive, as the repair will require working through both layers.
- Shorter Lifespan - While this process can extend the life of an existing roofing system, adding materials over older ones will only do so up to about 10 years regardless of the life expectancy of the new shingles. It is what is underneath that becomes the problem as time passes.
- Insurance Issues - Most insurance companies will only insure the top layer of roofing materials, meaning anything that happens beneath them is not covered, regardless of how it happens.
Discuss Roofing Replacement With A Trusted Roofing Contractor
Knowing all these pros and cons, should homeowners consider re-roofing?
That will depend on each individual circumstance.
There is no doubt that a full roofing replacement is always recommended when a new roof is needed and most roofing services will assess a home to see if re-roofing is even possible.
Other roofing contractors suggest against it in most cases.
A good recommendation is for homeowners to discuss it with their roofing contractors to make the right roofing decision for their homes.
