Roof Pipe Vent Flashings & Screened Covers

Here's an octagon shaft pipe vent cover w/simplistic seamless weather-heads

I first made a chimney flashing kit for this client: Vince Visoskas in Chester Springs Pennsylvania. Then he asked me to make this set of 2 roof flashing pipe jacks for some 3" ABS sewer pipes. They were built to the clients specifications to go on a 7.5/12 pitch roof with a 4" inside collar to go over the plastic pipes and a w/stainless steel screen to keep pot pests. The collar was made 12" tall and the base flange extends just 4" out from the side.

Cost: $100 each packed in the same wood crate as the chimney flashing kit (11/12)

Here is a round shaft pipe vent cover w/o weather-heads.

I first made a turret roof cap for this client: Ducote Construction in Alexandria, Louisiana. Then he asked me to make this set of 4 roof flashing pipe jacks and the roof vent seen below. They were built to the clients specifications to go on a 12/12 pitch roof with a 5.25" inside collar to go over some natural gas exhaust pipes. The collar was made 18" tall on the high side and 23" tall on the lower side.

I later found out that the contractor was thinking that I was going to make covers for these like the turret roof cap I made him, to shed the rain. Although through out the quote process he had not mentioned that detail. Being a Roofer I expected he knew just what he wanted and I did not imagine I needed to ask him if he wanted rain covers for these. I had sent him these photos through e-mail well before they shipped out and he had not said a word about the covers still. It was not until after he had received them that he wrote asking where the covered were. I offered to quickly make them for him, but it would cost more, since they were not in the original contract. He could not wait and needed to figure something else out. I never found out what he did with these. The point being; how important it is to make your expectations clear.

Cost: $240 each including the wood crate and shipping (4/09)

Deluxe Tapered Screened Flashing Covers for Pipe Vents

These pipe vent flashings were made for a contractor; David Lee of Casey/Lee Builders in Birmingham, Alabama, Ph# 205-229-1245.  These were made to cover some 3" plastic vent pipes through a flat roof that is covered with copper, so there are to be soldered down in place. That is why I made the bases wider to help keep the heat away from the plastic pipes while soldering them down. This taper also adds a good deal of stability to the 18" tall cone. These did not need a wide flashing flange, but if they are used for a tapered roof with shingles they would need a 4" to 6" flange out past the base of the vertical sleeve.

He wanted 2 of these with a screened cap over the top, where the other two will just have the top cut down vertically on the bends to bend the extra copper down inside the vent pipes.  These have a base that is 7.5" inside with a 10" wide flange. The cap is also 10" wide. The 8 bends add a good deal of strength and also help make these more uniform than a circular tube, as seen below these.

Cost: $237.50 each for the capped units, and just $157.50 for the pipe jacks
including the wood crate and shipping (6/09)
