Problems with Joists and Rafters
Joists are the large blocks of wood that run parallel to each other across the ceiling. Rafters are vertical beams that hold that actual load of a roof (for example the shingles) and makes up the roof’s framework. The joists and rafters work together to support the walls of your home and your roof. When these beams become worn due to wear and tear, aging, and in some cases extreme weather, they lose their strength. They begin to dip under the strain and thus, causes your roof to sag.
Too Much Weight
Another common cause for a sagging roof is too much weight. Your joists and rafters can lose structural strength over time. The weight that comes from items like heavy shingles, snow, puddles, and debris can cause your roof to sag. Even sloping roofs can still collect snow and debris. Eventually, the weight becomes too much for your roof to bear.
Weather and Time
Besides the snow, the sun and rain can also wreak havoc on your roof. The UV rays of the sun can weaken away the surface of your roof over time. Shingles can crack and rain water can seep in through these cracks eventually reaching your rafters. The moisture can lead to rot which weakens the rafters and eventually cause sagging.
Of course, sagging is not the only issue you could have with your roof. Here are a few more reasons why you may need to look into the services of Seattle Cedar Supply roofing.
One of the easiest ways to determine the health of your roof is by inspecting its shingles, as the state of your shingles can tell you a lot about your roof. Missing, broken, and cracked shingles are often a sign of a worn out roof that needs to be replaced. Shingles that are curling, buckled, or are missing granules are another sign to look out for. While a few problem shingles can be replaced, widespread shingle damage on your roof is a good sign that your roof is in need of replacement.
Signs of Leaking
Inside of your home, it is important to be on the lookout for signs that your roof may be leaking; this is often easiest to see from within your attic. Signs of water damage can include streaking on the underside of your roof and along your attic walls. Another sign that can indicate a leak would be discovering damp insulation in your attic. Either of these signs should be cause for concern, and reason enough to have a specialist take a look at your roof.
These are a few of the easiest signs for homeowners to identify that can indicate that their roof may need to be replaced. However, many of the signs that can indicate a roof needs replacing are more subtle and difficult for the average homeowner to detect. If your roof is aging and you suspect that it may be in need of replacement, it would be a good idea to have it looked at by a specialist who can help you to decide whether your roof may need repair or replacement.
