Signs that your roof has reached the end of its lifespan are obvious: consistent leaks, shingle loss, and mold growth.  Some homeowners might assume that a roof replacement means completely stripping off the existing roof.  However, that is not always the case.  If your roofs’ sheathing and shingle structure are both mostly intact, some roofers will apply a new layer of roof shingles right over your first layer.  This can be a quick, cost-effective option, but most building codes allow up to two layers of organic or fiberglass asphalt shingles for roofs with up to a 4:12 pitch.


There are several factors that might lead your roofing professional to recommend adding shingles on top of your existing layers.  One of these major factors is cost savings.  By leaving the existing layer of shingles on your roof, you’ll save on both labor costs and disposal costs.  Adding shingles adds up to an average savings of about $1,000 less than a full roof tear-off.

Homeowners are legally limited to two layer of roof shingles.  Therefore, if you already have two layers, you’ll need a full tear-off.  Additionally, if your roof is severely damaged, it won’t be able to support the weight of a reroof and will need to be torn off. Ultimately, it’s best to work with a roofing professional to determine if your roof is eligible for re-roofing.


Roof maintenance is a major part of any homeowner’s responsibility.  A roofing specialist should inspect the roof twice a year to prevent any minor repairs from becoming major problems.  Although roof maintenance tasks are typically minor and quick, it’s crucial to stay on top of repairs to avoid costly, time-intensive repairs down the line.  If you notice any of the following issues, reach out to your roofing professional to schedule a quick repair or a major remodel:

  • Buckling, curling, or blistering shingles
  • Cracked caulk or rust spots on the flashing
  • Damaged, ineffective gutters
  • Damp stains on your ceiling, especially in the crawl spaces and attic.
  • Leaks or excess moisture in the attic
  • Missing granules on shingles
  • Missing or broken shingles
  • Missing or damaged chimney cap
  • Rubber flashing boots that are cracked or worn
  • The flashing shows complete signs of damage.
  • The chimney masonry showing signs of cracking


New Roofs

new roof installation is the best thing when the supporting structure is damaged.  You need to ask about a new roof’s durability and structural integrity.  Roof replacement is expensive but delaying the installation would damage your property and result in costly home repairs.

You can pick from a range of roofing options based on the style of your home, roof material, color, and durability.  The type of material you choose also depends on your personal living needs.  For example, there are varieties such as metal roofing, traditional shingles, forged iron, and more.  Professional contractors will help you choose the best roofing material for your living needs.

Once you know which roofing material is best for your home, it is time to hire a professional contractor.  Research online and shortlist at least five names and pick the one that has the best customer reviews.  Ensure that the contractor also has at least 10-15 years of experience in the roofing industry to avoid scammers.  A new roof means huge investment and therefore, you need professional people to do the job.  It will help you get the maximum value out of your money and a roof that could last a lifetime.


There are a couple of things to consider such as removing the loose things from the shelves and walls because hammering on the roof could lead to vibration making items fall.  Make sure your driveway is clear and the areas close to your home because your old roofing materials might fall on the driveway and surrounding areas.  A professional contractor will have a rolling magnet that can collect loose nails from the surrounding landscape.  The contractor will need to use the driveway to park their vehicles and equipment during the job.
