Signs a roof must be repaired or replaced

^METRO

The exterior components of a home, such as the siding and the roof, help to protect its occupants from the elements. While many roofing materials can last for decades, at some point in time homeowners will likely have to repair or replace the roof on their home.

Roof wear and tear may not always be so evident, particularly because most homeowners do not make it a point to get on their roofs very often. The first sign of roof damage typically is a leak that is noticeable from the indoors. It may include a browned spot on the ceiling or even pooling water in the attic. Leak from storm damage or something minor like a water intrusion through a nail hole or from a lost shingle typically can be repaired easily enough. However, additional indicators may necessitate a complete roof overhaul. Here are some signs a roof is in need of repairs or replacement.

• Sagging roof: If the roof is sagging, it could be due to excess loads, such as water-damaged shingles or even weakened roof structure. A professional will need to restore the integrity of the roof.
• Cracking and buckling: It is likely that shingles will have to be replaced if there is cracking or if shingles are buckling and warping.
• Exposed nails: Exposed nails may rust and contribute to a leaky roof, says Family Handyman. How long the nails were exposed could indicate if the roof can be repaired or if everything should be redone.
• Lost granules: Asphalt roofing shingles have small granules on the surface. Over time these granules will slowly degrade and fall off. If there are many granules in gutters or if one can see that portions of the shingles are bare, it is likely time for a new roof.
• Visible light: Homeowners who can see light streams coming into the home need roof repair. This is indicative of holes, cracks or spaces in the roof.
• Growth on the roof: Mold and mildew on the roof is a sign that the roof needs to be repaired or replaced. Such growths contribute to rot that jeopardizes the integrity of the roof.
