Buying A Home With An Old Roof

The home-buying process is filled with emotional highs and lows. Few feelings are better than finding a perfect house in your price range. But your excitement can be quickly derailed if the home has a roof well past its prime.

Purchasing a home with an old roof is not always a bad idea. In certain instances, this imperfection can present an opportunity to buy a great house at a bargain price. However, several things must be considered before signing on the dotted line.

Buying a home with an old roof

Roofs are not all built the same. It’s important to consider several factors when determining the remaining lifespan of an existing roof. Some of the most important factors include:

• Roofing material
• Installation quality
• Climate
• Condition

Roofing material

Asphalt shingles are the most common roofing material used in North America. Unfortunately, they have a relatively short lifespan of about 15 to 25 years. On the other extreme, slate roofs often last 100 to 200 years before needing to be replaced. The list below provides the typical lifespan of popular roofing materials.

Estimated lifespan:

• Asphalt shingles: 15-25 years
• Wood shake: 30-50 years
• Metal: 40-70 years
• Concrete tiles: 25-70 years
• Clay tiles: 50-100 years
• Slate: 100-200 years

Installation Quality

Using a high-quality roofing material does not guarantee a long-lasting roof. In many instances, the installation quality is the most important factor. That’s why it is always wise to get an inspection from a roofing expert before purchasing a home with an older roof. You may find that the roof is in better condition than expected or that it must be replaced immediately. Either way, you will have a definitive answer before laying out a down payment.


Extreme climates tend to shorten the expected lifespan of many roofs. For example, Florida’s hot, humid, and storm-prone climate puts a lot of additional stress on roofing systems. In a location like Florida, keeping up with regular roof inspections and maintenance is essential to get the longest life possible out of your roof.

When buying a home in an area with an extreme climate, it’s always best to be a bit cynical about the number of good years your prospective roof has left before needing replacement.


Condition is the most critical factor when buying a home with an old roof. If the roof is in poor condition, you should request a significant discount on the purchase price. After all, you must replace the roof quickly before the home suffers damage. On the flip side, if the roof is in good condition, it may be many years before a replacement is needed.
