Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

  1. RECYCLING - Metal roofing is recyclable when removed as part of a demolition or renovation, whereas asphalt shingles go in the landfill. It is a considered a “green” construction material.

  2. STORM RESISTANT - When installed to the manufacturer’s specs, a metal roof will easily resist hurricane-force winds and is the roof of choice for southern coastal areas. Also, asphalt shingles lose their storm resistance as they age, but metal roofs do not.


  1. AESTHETICS - While a metal roof will likely increase the resale value of your home, some homebuyers do not consider them to be aesthetically pleasing, and associate metal roofs with barns and commercial buildings. Also, a few homeowner associations limit the allowed roof material to shingles.

  2. REDUCED CELL-PHONE SIGNAL - If your home is in an area that has a weak cell-phone signal, you will notice that it diminishes considerably when you are under a metal roof.

  3. REQUIRES MORE SKILL TO INSTALL - Not all roofing contractors offer metal roofing. Asphalt shingles are simple to install in comparison with metal roofing, so it’s important to get a knowledgeable and experienced roofer for a metal roof.

   There are also several popular myths about metal roofing that are nonsense. They are not noisy in the rain (unless the roof is installed on a barn with no underlayment or roof sheathing), and they do not attract lightning. Buckling of the roof surface due to excessive expansion and contraction of the metal is sometimes argued as a defect, but this problem only occurs in a poor installation.

   After weighing the pros and cons, metal roofing is an attractive option. Obviously, though, if you are planning on selling your home within the next 5 years or so, a metal roof is an uncertain investment compared to the universal acceptance and low cost of shingles.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
