When you’re shopping for a new home, the roof is one of the most important and expensive features you should be looking at. We’ve compiled a list of things to look for in a roof when you’re considering buying a house.

Age of the Roof

Depending on what type of roof it is, its lifespan will vary. An asphalt shingle roof typically lasts about 20 years, while a metal roof can last up to 70! Ask the owner how long they have had the current roof, its composition, and if they are having any issues with leaks.


Leakage typically occurs in valleys and chimneys during hard rainfall. Inspect carefully for any signs that the roof is leaking. Check for loose, broken, or curling shingles where water could get through. Also, look in the attic for signs of water damage.

It can often be difficult to find the source of a leak. You may need a professional to come and assess the roof. Be sure to factor the cost of a roof repair or replacement into your bid on the house.


Mold is a fungus that comes in various colors, including black and green. It may be difficult to see on a roof, but it will wreak havoc if it gets into your home. The main source of mold is water leakage.

In addition to looking bad, mold can cause terrible odors and affect the health of those living in the house. If there are signs of mold inside, you’ll need professional mold remediation to get rid of it. Home remedies will not work, and the mold will come back.

Gutter Systems

A house needs a gutter system that will lead water away from the roof and the home. Inspect gutters and downspouts to be sure they are unclogged and not just dropping water into the ground close to the house where it can get into the basement.

When checking the gutters, if the roof is made of asphalt shingles, check for granules. Excessive shingle granules are a sign of roof age and may indicate that it is time for a new roof.

A roof is one of the most critical components of a home. Ask questions, and look carefully. If you aren’t sure, ask a professional to come and inspect the roof before putting in an offer. A new roof is a considerable expense, and you’ll want to factor that into your home bid.
