2 piece electric mast pipe flashing?

4just1don

I have an electric entrance mast in a 2 or 2 1/2 " pipe coming up thru the area I am building new soffits on edge of roof. Has the wires attached,the head, clamp to hold it to house,,,so easiest would be a two piece flashing. Do they make such an animal? is there a name for it? best install procedure?

I assume lots of blackjack involved. Do they make those that size like metal chimney flash?

thar was VERY helpful,,,never heard of that product.

On a related note the last time I did roofs back in the 80's I used all new vent flashings etc. NOW those rubber components are in appalling condition,,,obviously failed and leaked long before the roof did. Would it hurt or help to put tin flashings above the rubber part,,,much like an umbrella to keep direct sun off the rubber??? Or would that cook the rubber even faster,,like sticking them in a constant tin oven???

If it matters,,location is northern Nebraska,,winter lows of 20-30 below with -80 wind chills and summers heat of 95 to 105 regularly. Dont really know why we live here some days.

It won't hurt to put a storm collar of sorts over them if you like. This is one of the rare times I will tell someone to use some mastic or caulk to coat the damaged gasket.

If they are degraded to the point of failure you can also consider replacing them. I don't know the condition of your roof or your adeptness at doing something like that but you may need a few shingles to replace ones you may damage.

A flat bar and a hammer is about all you need. gently loosen it and the shingles around it. Remove it and install the new one with a nail on each side to hold it in place. Then re-nail the loose shingles around it.
