While you may only see problems with your roof in the valleys on top of your home, this is one way in which your roof will beg for replacement. These are "high traffic" areas for water, so damage will almost always begin here first. Once it starts, it is time to replace your roof.
Avoid ice build-up on your roof in the winter time. This potentially devastating situation occurs when snow begins to melt close to the interior lining of your home, then freezes, creating a seal. That ice can remain for a long period of time with low temperatures and create leaks and warping. Proper ventilation and insulation should remedy the problem.
If someone comes to your door and offers you a free roof, question their motives. Don't let them up onto your roof - instead, call your insurance agency and ask them to inspect the roof. Until the insurer says you need, and will be covered for, a new roof, don't sign anything.
If you are trying to pinpoint the exact point where your roof is leaking, you can spray it with a hose and see what areas create a problem. Do not try this method in the winter, because it is not safe to spray water on the roof while the temperature is very low.
Find out about roofing warranties from your roofer. Roof replacement and repair can be expensive, so you should always choose a contractor that offers warranties for the work. Professional contractors usually offer full warranties on new roofs or roof replacements, but they may not on repairs. Always get a copy of your warranty when the work is done.
Make sure you install a ridge vent into your roof so as to prevent dry rot from occurring. Contrary to popular belief, dry rot is not caused by water damage, but rather a lack of ventilation. Installing a ridge vent will ensure that your roof is properly ventilated throughout the year.
Spray your roof with a garden hose to test it out. This is a great way to see if there's a leak and you can also see where the leak is coming from. You will not have to spend money on a contractor just to find out.
Don't pay until the roofer finishes the work. While you might have to pay a small deposit, it shouldn't exceed 25% of the project's full price, or the base cost of just the materials. Never pay for labor in advance. Make sure you always look at completed work, then get copies of all important paperwork before you pay the roofer.
Get free quotes. Roofing prices can vary from roofer to roofer and you want to find out what the different prices are in our area. Be sure, though, that when you get prices you are getting the estimate for the same type of shingles and the same service from the roofer.
