Your roof is a part of your home that needs constant upkeep and regular maintenance. When you neglect this vital part of your home it can result in unnecessary stress, major costs and decrease the real value of your home. Simple repairs and maintenance can help you to avoid major renovations. The key to avoiding these costly mistakes is to know what you should be looking for. Here are 5 of the more common tell-tale signs that you may need to replace your roof.
1. Bald Spots, Damaged Granulation, and Moss on your Roof
Over and above loose or misshapen shingles, one of the more common signals that you might need to consider a roof replacement is when the shingle have started to lose granulation. Most shingles are reinforced with a barrier made from protective granules. When this barrier starts to wear away, you will notice bald spots on the roof. The bald spots don’t typically occur for over a decade or two, but once this begins it speeds up the aging process of the shingles and will eventually result in leaks.
You may also notice moss starting to grow on your roof. This most often occurs on houses with trees nearby where the roof does not get a lot of sun and/or when the roof has a flat pitch. The roof does not have time to dry out or the slope doesn’t cause the water to run off fast enough, the moisture remains on the roof, and over time moss begins to grow. In both cases, at minimum maintenance is required if not an entire roof replacement. It is likely the plywood underneath the underlayment is rotting because of the excess moisture.
2. Flashing Damage
The flashing on a typical roof is located around the ventilation stacks, chimneys, and skylights. These are the areas that are the most vulnerable to water damage as they stick out of the house, where the shingles lay flush with the slope of the roof. Over time, metal flashing wears down and begins to deteriorate because of exposure to the elements. When flashing isn’t properly sealed, water will get behind the flashing and freezing and thawing will continue to expand the damage. Eventually, water will enter the home and you will begin to see water spots on your ceilings and potentially in the walls. This can cause a massive mold issue in conjunction with the problems in the roofing system. This is the reason why most of the experienced roofing contractors will recommend a bi-annual inspection of your flashing. If you notice any damage to the flashing in your home, try to have it repaired immediately.
3. Blistering And Cracked Plaster Or Paint
To assess the current quality of the roof over your home and its overall protection against damage from wind and rain, walk around the inside of your house. Look for blistering plaster or paint, or cracks on the exterior walls and discoloration in your ceiling. These signs usually mean you either have a ventilation problem or leakage issue. Blistering or cracked paint usually means there is moisture in the spaces in your roof, which are now seeping into the plaster of your walls. Discoloration of a ceiling likely means water has been dripping onto that spot then drying over a period of time. This can cause mold and mildew growth, and potentially worse.
4. Damaged And Buckled Shingles
Your roof’s shingles can be an obvious sign whether your roof has any issues. When inspecting the shingles, look for shingles that have started to curl up on the edges, or look damaged or loose. Damaged shingles often come off the roof during a severe rainstorm or strong wind so after the next storm, walk far enough away from your house to review your roof.
Buckled shingles usually appear in groups that typically run in a vertical pattern along the roof’s slope. Because they appear in groups, this is a critical problem that can make your roof vulnerable to elements. If you notice that most of the shingles on your roof are damaged, buckled or distorted, you might need a repair or replacement.
5. Water Or Ice in your home
When you are having problems with your roof, the first place the water will go is the attic. If you think you have a leak, this is the first place you should check. If you see standing water in your attic, wood that looks wet, or water stains on your ceilings, these are obvious signs of a leak.
If you have run into any of these problems and the damage is extensive, you will need to think about a roof replacement. Replacing an old roof may be costly but you need to keep in mind that your roof is what protects you and your home from the elements. An old roof can drastically reduce the resale value of your home, so a replacement would be in your best interest if you would like to maintain your home’s value and aesthetic appeal.
