Since a new roof may cost between $4,000 and $10,000 it pays to keep the roof of your house in good shape. After all, a damaged roof can lead to far more than that those costs in terms of attic and ceiling damage, interior mold and mildew, mold health problems, fire damage, and overall structural integrity of your home.
So how do you know you may need a new roof?
1. Check in your attic.
The first place to look is not on top of your roof but your attic. Climb up there with the help of a flashlight and look beneath the eaves. If you see sunlight peeking through, that’s a bad sign.
If you notice sunlight peeking through, not only does it mean your roof is leaking but there can be mold and wet spots in the insulation and on the ceiling joints.
And while you can do this as an amateur, you’ll need a professional roofing company to make the repairs.
2. Check your roofs age
Get out your homeowner’s paperwork and determine your roof’s age? A newly built roof should last around 20 to 25 years for an asphalt roof.
However, ir your roof is getting old, or there are actually several layers of shingles atop your roof, then it’s likely you need to contact a roof repair company.
3. Are your shingles buckling or curling?
Climb up on a ladder and take a good look at your roof. If you notice a lot of shingles either buckling or curling around the edges, then it is very likely you need to call in a roofing contractor.
4. Notice your roof valleys
The valleys of your roof are the areas where different angles meet and produce a valley.
Valleys are one of the areas that you are most likely to see missing shingles or shingles that fall apart. Snow and rain travel through these valleys towards your gutters, and if there are missing or damaged shingles in the valley areas, chances are likely you will experience a roof leak.
5.Shingle granules in your gutters
Your shingles may appear as if they are all intact but one of the first things that roofers check when they are called in for a homeowner roof inspection is the gutters.
If there are lots of little roof granules in your gutter it means your shingles are on their last legs.
Also, your shingles should be a constant color. If there are patches of dark shingles or light shingles, again it’s a sign that you likely need a new roof.
6. Check the flashing if you are able to
If you are young enough to climb on your roof and check your flashings around vents, chimneys, and skylights. In older homes, in particular, flashing was often made of tar or roof cement.
Flashing areas often crack or break leading to water leaks. Modern homes have metal flashing systems and if you do wind up calling a roofing company, make sure they upgrade your flashings on your home.
7. Roof sag
If you notice parts of your roof sagging, you definitely need to get this fixed. This is often a sign that beneath your roof support beams are rotting. In addition, roof sage can be due to the original builder using poor materials, not really installing the roof correctly, or possibly sag due to weight from snow and ice atop your roof.
8. An algae or moss factory is growing on your roof
If there is an algae or moss forest growing on your shingles it means that a lot of water is present on your roof. While moss or algae may not appear to be a problem outside of aesthetics, algae and moss can deteriorate your shingles and water can make its way to the support beams underneath resulting in rot.
And whether the algae or moss is due to a poor ventilation system or a blocked draining system, you should get a pro to check it out.
9. Water damage on your ceiling
The first sign of a leak in your roof is often a noticeable water stain in your ceiling.
This means water is already leaking from your roof, and it is not something you want to ignore as the resultant water can lead to serious health problems as well as damaged household goods if the water leak gets too bad.
What to do if you notice roof damage?
Call a professional roofing contractor and have them do an inspection. In particular, where leaks are causing rotting in the support beams or have already penetrated to the ceiling of your home, you cannot afford to wait.
