‘BURNING DOWN THE HOUSE’: GREAT SONG, NOT A GOOD IDEA FOR YOUR HOUSE

It’s surprising how often I come across this issue when doing home inspections: metal flue pipes serving furnaces and water heaters that come in contact with roof sheathing and underlayment in the attic. When this occurs, it’s a very obvious safety issue.

This issue is especially common when roofs are replaced. Why? Contractors may neglect to appropriately cut back roofing materials during installation. 

If you want to make sure your home doesn’t inspire David Byrne to write another song about burning structures, you’d be well-served to provide 1-inch of clearance, free and clear, around the flue pipe at all times. And again, this is especially important if you have had your roof recently replaced.


VIDEO: Discovering Deteriorated OSB Eave Sheathing Behind Gutters!

Tim Hance with All Islands Home Inspections recently discovered deterioration and fungal growth at OSB roof sheathing immediately behind gutters at a recent Oak Harbor, WA home inspection. It is important to keep gutters clear and free of debris to help prevent spillage that can lead to sheathing deterioration. Also, although not per se required, I always recommend installing a metal drip-edge flashing detail at all eaves (e.g., behind gutters) that is run underneath the roof coverings and over the fascia trim to further prevent water damage in the event that gutters overflow or water is introduced.
