Residential Metal Roofing: Is It Right for Me?

When the contractor delivered the sad news that my roof needed replacing, that led to a discussion of material choices. I was surprised to hear that metal roofing was an option. Sure, it was fine for commercial buildings, but a home? My contractor told me that metal is used for homes more than people realize. The panels can be designed to look like just about any type of roofing you can imagine. After looking at some samples and finding out about the long life of metal roofs, I decided to give it a try. Fifteen years later, my roof is still in great shape. If you are facing a roof replacement in the near future, let me tell you more about metal roofing. I'm betting that you'll decide this solution is right for your home.

Considerations For Homeowners Regarding A Second Layer Of Roof Shingles

by Kelly Murphy

When homeowners need a new roof and cannot afford to have the old shingles removed and replaced, a process known as reroofing may be suitable. This type of roofing installation adds a second set of shingles over the existing layer. Because there are disadvantages to this decision, contractors advise against it unless this is the only way to resolve leaks around the home.


One major issue is that a second set of shingles nailed over an old, leaking roof will not last as long as full roof installation. New roofs last an average of around 20 years before problems occur. Although patching might fix one leak, flaws will soon develop in other parts of the structure.

Covering the roof with more shingles does not actually fix the problem, although it delays the need for full replacement for about another few years. The homeowners must plan for how they will pay for that substantial home improvement work in the future. A third layer of shingles cannot be added because that puts too much weight on top of the building.

Possible Underlying Damage

Household residents don't always notice roof leaks quickly because drips from ceilings can occur in hidden places, like seldom-used closets. A long-standing problem may have caused water damage to the decking material under the shingles. That cannot be repaired or replaced with the reroofing option.

Resale of the House

A related problem involves a plan to sell the home after a number of years. Interested buyers may not want a house that will probably need a new roof so quickly and has just been reroofed. That would add a major expense on top of the price paid for the real estate. For many property owners, this is the largest home improvement project they will ever have done. 

Aesthetic Qualities

A double layer of shingles does not look as streamlined as a single layer. While one set sits evenly on the decking material underneath, a second layer could appear a bit warped in some places. Although people generally may not spend time looking at roofs, those living in neighboring houses may find the difference noticeable as they see the house every day. 

Making the Decision

Homeowners who simply cannot pay for a new roof must resolve the leaks somehow. They might be ineligible for a second mortgage or a home improvement loan. The second set of shingles should buy them another few years. When they're ready to get started, they may call contractors for estimates.

Reach out to a professional about roofing installation to discuss the cost of a new roof versus reroofing. You may find that it will be worth it to get a new roof because of the durability and repairs that come with a new one.
