This will depend on the type of roof that you have on your property. Most homes in the Northern Virginia area have asphalt shingle roofs. Most standard asphalt shingles have a lifespan ranging between 20 to 25 years especially 3-tab shingles.
If your roof has architectural or designer shingles then you could get up to 30 years lifespan whereas today’s architectural shingles have up to a 50-year lifespan. With this said the current age of your roof can be an indicator of the need to replace it with a new roof. As asphalt shingles age, they experience granule loss which protects the asphalt from breaking down from UV light so if your shingles are experiencing significant granule loss it is time to replace your roof. The edges of your shingles will begin to curl as they age and become brittle, this means they are most likely no longer sealed and can blow off during thunderstorms and allow water to enter your home. If you can see your shingles curling at the edges it is time to replace your roof. If your roof leaks that doesn’t necessarily mean it is time to replace it, this might mean your current roof wasn’t properly installed or it has experienced some sort of damage and can be repaired to extend the life of your existing roof.
A smaller percentage of homes in the Northern Virginia area have standing seam metal roofs. These roofing systems cost much more than an asphalt shingle roof however they last much longer and provide a classy architectural appeal to your home. The longevity of your standing seam roof tends to depend on the coating/paint that was applied to the panels from the factory which most are covered by a 20-year coating warranty. Once the coating begins to fail that exposes the metal to the elements and can cause the metal to deteriorate creating holes in the metal which in return allow water into the roof system. Just like asphalt shingle roofs, the installation of your metal roof is also a factor and how long it will last, a properly installed metal roof shouldn’t depend on sealants to keep the water out. If the paint on your metal roof is peeling or flaking it is time to call Residential Roofers for an evaluation.
There are also many homes in Northern Virginia that are covered with slate. Slate roofs last a lifetime again if properly installed. As these roofs age, you may notice some missing or broken pieces of slate this doesn’t mean you need your roof replaced, however, you should get the missing slate replaced with new pieces. A slate roof generally won’t need to be replaced unless action hasn’t been taken to repair missing or defective slate and water has entered the roof system and deteriorated the wood decking beneath causing the fasteners to give way in return causing slate to come loose and fall from your roof which also creates a safety hazard to people below. If you have missing slate call Residential Roofers today for an evaluation.
While they aren’t as common as in the past, some homes in our area also have cedar shake roofs. Just like any exposed wood cedar shakes need to be maintained and have waterproofing sealers applied to prevent the wood from deteriorating. Most cedar shakes come with protective sealers applied that last for years, however, once that sealer becomes defective you need to have them washed and resealed or they will begin to rot. When shakes are aging they will split and curl at the edges, once this happens it is generally too late to save the roof and you will most likely need to replace it soon. Always remember that your cedar shakes need maintenance and if you are unsure of the condition of your cedar shake roof or when the last time it was sealed call Residential Roofers today for an evaluation.
