Roof Drains Done Wrong

One roof should never drain onto another roof. This will shorten the life of your shingles where the upper roof dumps water onto the lower roof.  Take this new home for example. The upper roof had gutters installed, but they dumped the downspouts onto the lower roof.  This took all of the water from the upper roof surface and concentrated it into a 4 inch wide pipe. Shingles were never designed to handle water volumes like that.

To make matters worse, at the other end of the home, the downspout flows water across the shingles. Shingles are not designed to be waterproof, but to shed water. Flowing large amounts of water sideways across the roof surface is inviting water to get under the shingles. Once that happens, it is not long before a leak will occur.

This was not a small home, but a large 5 bedroom home in a new subdivision.  I’ll say it again, if you are purchasing a home, new or old, you need a Licensed Home Inspector to go over the home with you.  It can save you much more than the cost of the inspection.

Citizen’s Four-Point Inspections: New Form, New Price

Citizen’s has come out with a revised Four-Point Inspection form. Insurance agents are supposed to only accept this form as of September 1, 2018.  In order for our client’s to have this form by that time, we will begin using the new form July 1, 2018. This gives 60 days for anyone to close and have the new form on hand.

The new forms asks for much more information than the previous form. In addition to everything the old form asked for, inspectors are now required to test most of your household appliances for a four-point inspection, report any visible signs of leaks on the ceilings or in the attic, take photos of each slope of the roof and each side of the home. Due to the increase in time to gather information and the increase in time to report the information, the price of this form must increase as well.

 

Plumbing Vent Boots

You see these on almost every roof.  They are the vent pipes that let the sewer drain pipes “breathe”.  Without vents, your drain pipes would not function properly.  Much like holding your finger over the top of a straw and finding out the liquid will not drain out of the straw, your drainage system needs to allow air in to allow liquids out.

Most of our vent drains have a lead boot covering them.  Something like this:

But if you have squirrels in your neighborhood, and they travel across your roof, they will often stop to gnaw on these lead vents.  Evidently, chewing on the lead feels good to them. The down side is that once they chew through the top of the boot, moisture (rain) can get into the home via the gap now in the system.  This water will drain down into a wall cavity where it and it’s associated damage are hidden from view.

Here we can see two examples of failed boots.  They both are allowing water into the walls of the home.

Draining One Roof Onto Another Roof

I see this quite often on two-story homes and condos.  There are nice gutters on the upper and lower roofs, but the upper roof drains onto the lower roof.

What the gutter installer has done is take all the water from the roof surface of the gutter above and concentrate it into one small area.  This is worse than no gutters at all.  Water will come out of the downspout with lots of velocity and force, quickly removing the protective granules from the shingles. This will quickly age the affected shingles, resulting in early failure of the roofing (a leak).

In the example picture, there is also a kickout used as a splash block to prevent the water from overshooting the gutter below. This will only serve to back water up in this area and drive the water under the shingles and behind the stucco wall .

Downspout

Improper downspout dumping water from one roof onto another roof

The correct installation would have the downspout extended to the gutter below and turned down into the lower gutter, or even better, have the downspout at a location where the water could be taken to the ground.
