How To Repair a Roof Valley – DIY

We just had a building inspection come back on the roof of our house stating that one of the valleys in our asphalt single roof needs repair. It has never leaked, and I didn’t think it looked all that bad, but the building inspector seemed to deem that the roof valley needs to be repaired.

Roof Valley Repair Needed

There is a little deterioration on the last few tiles that according to the building inspector means that the entire 20-feet of roof valley needs to be repaired.


I have been looking at how to do a DIY roof repair on the valley and came across this video of someone else doing a roof valley replacement on a house that needed it’s roof valley repaired:

While researching this problem I also stopped by Home Depot to try to get some advice. Do you ever feel like you know more about construction and house repair than the people who work at the those big box stores? That is kind of how I felt today as a “kid” tried to tell me I just needed some 4″ by 4″ metal flashing to fit in under some cut tiles.

Mate, that really doesn’t cut it …

After looking at what is involved I am feeling that the roof valley repair that I need doing may be a bit over my head for a DIY job unfortunately.

I’m going to be contacting some roofing companies starting with Epic Roofing and Cargan Roofing here in Calgary based on some recommendations from some friends to see what the price will be for this “little” job, ha ha. Actually, I reckon there is probably no such thing as a “little” job when it comes to a roof…

Cool Your House with your Range Hood

One disadvantage with having a very well insulated home is that in the summer the house takes a long time to cool off in the evening. Often with a house that is insulated well it also means that there are fewer windows and limited cross ventilation and cross breezes.

Recently we have been hitting over 30C in Calgary. It is nice for change during the day, but it leaves us with a rather hot house come evening when it is time for bed.

Last year we installed a new vented range hood in our kitchen. The range hood we got is a NuTone Deluxe Allure® III, which is rated at about 300 CFM on the “3″ setting, and 430 CFM in boost mode. I figured that is a lot of air to be pulling out of the house, so it needs to get the air from somewhere right?

When it cools down outside I find that I can open up some windows far from the kitchen, put the range hood on the highest setting and actually feel the air being pulled into the house from outside. It really seems to help to cool down the house…
