Long Term Roof Leaks

How long has it been leaking? Its my first question when someone calls about their roof; and sometimes its hard for my clients to answer.

“Not that long”; is by far the most common answer.

However, “Not that long” can mean a week , or it can mean three months and it can mean four years; it depends on the clients perception of time; sometimes the memory devices people use to date the problem can be quite entertaining. The all time longest was an elderly woman who was able to trace the start of her roof problem with the birth of her grandson in 1999; she called me in 2007.

Water damage happens slowly, then all at once.

Water intrusion is unique in the way it damages a house. Usually roofs don’t fail catastrophically, it starts small and slowly gets worse.

The faster you get to the problem the cheaper it will be to fix. If the leaky roof is ignored the damage  and cost for repairs grow exponentially; what might cost $565.00 to repair today could turn into $5,650.00 within three months. If water is allowed to come into the structure for extended periods you not only must repair the problem that caused the leak, but sometimes everything below the leak.  By the time three rainy months have passed  the insulation in the attic, plywood roof decking, rafters, drywall, electrical outlets, lighting and flooring may have been ruined. There are also mold and insect problems that come up when roofs are let go.

If you are having roof problems don’t wait to call; the sooner you deal with it the cheaper it will be. If cash is tight and you can’t pay for it all, ask us for help. If I can afford it I might be able to extend your time to pay. The universe has been good to me and i find that when I am good to others I’m rarely let down by them.

Ice Dam

Ice dams occur when temperatures are low and there are a few inches of snow on the roof. The only way to make it stop is by removing the ice and giving the water a place to flow safely off the roof.

It is extraordinarily dangerous work, so if you are going to do it on your own please wait until you can get a friend to help.

You can also hire a roofing contractor to do the work for you.

The right weather conditions for ice dams is usually when outside air temperatures are in the low 20s (°F) for several days with several inches of snow on the roof.

Research shows keeping the attic air temperature below freezing when the outside air temperature is in the low 20s can reduce the occurrence of ice dams. Research has also shown that sun exposure in the winter has little effect on attic air temperature. Warm air from living spaces below penetrating into the attic is usually the culprit in the formation of ice dams.

Watching the news for any more than 25 minutes will have pains shooting down your left arm; their job is to terrify you. They want you upset so you stay tuned during the Folger’s Coffee commercial. Most of what they are saying about the snow on your roof is pretty much all wrong.

When to worry:

1) You have water coming in through the tops of your windows or water coming in along the outside walls. If water is leaking into your house you must stop it, the only way to do that is to remove the huge chunks of ice that have grown along your gutter.

2) You heard an unmistakable cracking sound and then you saw a crack in the drywall at the ceiling or wall. If you saw or heard anything like that then the roof you are under is over loaded. NOTE: Residential roofs almost never fail catastrophically, under the current snow load you have a better chance of winning the lottery than you do of having your roof wind up in your basement.

When not to worry:

1) If your roof isn’t leaking now then chances are it probably won’t.

2) You have huge piles of ice on your gutter; it will melt, relax. The worst that can happen is that the gutter falls off, move the glass patio table out of the way so nothing else gets damaged.

If you are having leaking call us, we can help. Dont waste your money hiring someone to remove the snow from your roof because the anchor man with the comb-over  scared you into it.

When the snow and ice are gone you can call me to inspect for any damage.
