Questions to Ask Your Roofing Contractor About Your Roof

Do you have a roof that's starting to leak? Do you want to have it taken care of before winter rains or snows arrive in earnest? If you're not familiar with roofing materials, it can be difficult to decide whether you can simply have your roof repaired or if you need to have the whole thing replaced. In order to help you decide whether or not you have to spend money on replacing your entire roof, here are some questions to ask your roofer:

Can you tell how old the roof is? 

Although you may own the house, you don't necessarily know how old the roof itself is. The home may have had two or three other owners since it was last reshingled. The older a roof is, the more likely it is that it needs to be replaced. If the roof is leaking because just a handful of shingles are curling, split, or have blown away due to age, then your roofing contractor may be able to simply replace the damaged portions and you'll be fine. On the other hand, if the shingles are all a uniform age, and in a similar state of wear, then you should probably go ahead and replace the entire roof if at all possible. Replacing just a portion of the shingles may not do much to stop the leaks.

Was the flashing reused during the last roofing job? 

In order to save money on a roofing job, a roofing contractor will sometimes suggest to the homeowner that they will reuse the existing flashing to finish the job. Flashing consists of strips of thin metal that are nailed beneath shingles on the peaks, in the valleys, and around the vents in your roof. When flashing is reused, the roofers aren't always able to put the nails back precisely where they were before, allowing water to seep in through the old nail holes. If the flashing was reused, your roofing contractor may be able to simply replace the flashing to stop the leaks, instead of being forced to replace the whole roof.

How does the sub-roof look? 

Among other things, the sub-roof consists mainly of sheets of plywood that are used to hold the shingles in place. Unfortunately, a roof that may look fine to the average person may actually be full of hazards. If you have poor insulation in your home that allows humidity up into your attic or crawlspace, the excess moisture may get absorbed by the plywood and eventually cause dry rot. If just a couple plywood sheets are showing signs of decay, you can often get away with just replacing those sheets and the shingles on top. If the dry rot has started to spread over most of the roof, however, you'll need to replace everything sooner rather than later. Regardless, dry rot can be an indication that you need better ventilation for your attic or crawlspace and better insulation for your home in general.
