Roof Leaks – Why and Where

Your house is beautiful; everything is freshly cleaned and painted; you’ve done all your home maintenance. But with the first fall rainstorm, you find a leak! Those dreadful leaks that you have NO IDEA where they come from. It seems like the problem should be ‘just above’ where it’s leaking, but it never seems to be that way. Water can easily travel sideways before passing through a joint in the roof sheathing. The true point of the leak can be a distance from the apparent leak location.

Actually, roof leaks normally start in areas where there are ‘details’ like vents, chimneys, flashing or where the roof has ridges and valleys. A valley is a line where two roof planes intersect and can become problematic, especially if the shingles were not trimmed correctly.

Chimney & Flashing

Chimneys Are Very Common Leak Sources

Because chimneys use different types of flashing and the flashing that is supposed to waterproof the chimney can separate and then easily let in water.

Other reasons roofs begin to leak is simply the wear and tear of weather – temperature variations, rain and frost – and lack of maintenance. Water can enter the tiniest of openings. The old adage “if you don’t see it, you don’t think about it” certainly applies to people and roofs! Plus, most homeowners are not equipped to get up on their roof to check everything, even if they knew what to look for.

Roof Inspection

So, while a professional roof inspection may cost a few dollars, it can save thousands in the long run. Small repairs and good roof maintenance to prevent leaks can result in major savings … for the water damage that did NOT happen in the home.
