A shed is born,finally

Very nice. I really like the two colors that you used and how it sets the building off.

I don't see any vents. How is it vented?

As for the base for concrete, sand is about the best you can use. It compacts the easiest and is also fairly cheap.

Thanks Eddie. Venting.I didn't think of that so I took a look and the soffit has vents about every 2 feet around the building.I hope that will suffice.

Heat rises. Soffet vents are to allow air to circulate along the bottom of the roof as it rises. You need to have a vent along the peak to allow the air to exit the building. If you do not vent it, you will trap the warm air and create a condensation nightmare. It will be like rain on the inside of the building.

Luckily it's an easy fix. Your builders should have bout some roof vents that go on the peaks. They just have to unscrew them and install the vents. You have quite a few options, with apperances being the biggest deciding factor. Some of the more expensive ones allow you to open and close them. This is nice if you heat or cool the building.

Bones,
I had to replace my house roof because of the lack of venting. A new roof was installed on my house a few years prior to my purchasing it. The roofer installed the metal vents but the soffit was totally enclosed. The soffit was covered with the perforated aluminum normally used on vented soffit but the aluminum covered solid wood so no air was allowed to rise and vent my attic. The attic was insulated with fiberglass but the fiberglass was forced into the soffit area so if it was vented the air still would not flow. I had to replace the 1"X8"s and the OSB because they were rotted in many places and covered with a black mold. I had a little extra work done and the total cost of the roof replacement was around $14,000. The original bid was$9000. My roofer opened up the soffit and put on full length peak vent material. Moisture had no place to go so it covered my roofing base material and destroyed it.
Attic venting is critical as I found out the hard way.

6/12 pitch, color combo, concrete floor. Awesome! Was there a big cost difference from the standard 4/12 vs. the 6/12?

bones1 · Feb 18, 2007

Thanks Keving.I think the 6/12 pitch looks better and my best estimate is it cost about $400.00 more.
Farwell and Eddie.You got me thinking about vents now and I'll look into that.I do have bubble-foil insulation under the roof that's supposed to help a lot with condensation forming (raining inside).

Bones,

thank you for sharing it with us. Beautiful structure, I don't think you would have any moisture issue , since a humid hot air will not come in contact with a cold roof surface, thanks to a bubble roof insulation. If there's any condensation it may occur on the side walls....but hopefully the soffit vents are big enough, so you are fine.
Your contractor seems to be very professional, he should have this basic knowledge. I would trust him.
Good luck with your vette project.

Thanks Praha.I think we'll be fine with it.Been draggin that old Vette around with me for 5 years, now it will have a home.Just have to find all the pieces.

Bones,

I concur with all who have said that it’s a beautiful structure and thank you for sharing it with us.

As far as the question of venting, I think I can see the light coming through the top of the roof and it appears in picture that there is a gap of several inches at the ridge after the roofing panels have been installed. If so the cover on top of the panels would the finish the venting system allowing air to escape between the cap and the panels. On a dark night shine a good light up there and you should see the gap inside and some light reflected to the roof on the outside. Or throw up a ladder on the inside and take a closer look.

Praha may be correct, but it doesn't make any sense to me.

Even with insulation, there will be a tempature change on your roof compared to the surrounding air. When air temps either cool or warm because of the roof, you will have condensation. It might be less with the insulation that you have, but I don't believe it will be eliminated.

I aslo agree that your contractor has done a realy good job for you. Have you asked him about venting? I'd really love to hear what he says about not venting at the peak and why he doesn't need it.

Thanks,
Eddie
