One particular part of the house that people really like to ignore is the roof. It's way up high and out of sight, and they're expensive to repair and replace. That's not always a good thing though, because sometimes a little care and maintenance will increase the lifespan of a roof and far outweigh the repair or replacement costs. Many roofs that look good from afar are in really poor shape if you actually get up close and inspect them. Let's go over some of the warning signs you should be aware of.

Sometimes a leaking roof will only be a small pin stream of water that gets absorbed into the underlying insulation and sheet rock. However, years of leaking could be causing dry rot in the rafters that are incredibly difficult to fix. When viewed from the inside, you may notice a small discoloration on your ceiling. That's the best spot to start your search.
Many times the water is leaking much higher up and then running down through multiple roofing layers before exiting inside the house. As the water progresses downward, it is causing all kinds of potential problems so it should be taken care of immediately.
When you get up on the roof, you might find that the roof looks great right above the leak, but if you investigate further up, there might be a missing shingle that needs to be replaced. There is also the possibility of piles of leaves or moss growth as well.

Usually on the north-facing part of your roof or any part that is shaded a lot, you may find moss growing. Moss causes water to stay on the roof and allows it time to soak in instead of running off as it should. You need to gently remove all the moss and any other leaves or debris from your roof twice per year.
Moss and lichens can be killed by spraying zinc-based chemicals or by inserting a solid zinc flashing at the very top of the ridge of your roof. The zinc will leach down during the rain and continue to kill moss and lichens. This can extend the life of your roof considerably in moist or shaded climates.

Shingles tend to get the most wear on the very tip top of the roof - called the ridge. If you inspect it and see that many of those shingles are cracked, you should replace them all. It's not a complicated job, but if you're not comfortable on a ladder, you should have a roofing company do it for you. With a bit of research, you should be able to find a reputable roofing company in your area. In fact, in just about every suburb near major cities, you can find proven companies to help you. For example, this Naperville contractor provides roofing and exterior services and offers assistance over the phone as well. The same goes for the valleys - they get more wear and deteriorate faster than the rest of the roof, so you should inspect them frequently and fix them before more problems arise.
By taking good care of your roof and inspecting it yearly, you should be able to get a longer lifespan from your shingles. You'll also save money on replacement of dryrotted rafters and stained sheet rock if you catch and fix problems early.
