how do you figure shingles for roof ?

[stitan06]

i have been looking at valley on diff roofs around here and at work the ones we have done in the last few years we " laced the shingles in the valleys " not sure if thats the right term.
i like the finshed look that the lacing gives them . as far as underlayment im looking at ice guard on bottom then titanium paper the rest. ok forgot this question not really bout roofing per say i have ridge and eve vents also last homeowners had a attic power fan put in , the home inspector said they should be together counter acting one another from i have found thats true? i was gonna do away with attic fan and just run ridge vent and eve we is that the common/right way ?

This is NOT an indictment...can't stress that enough.

About the only thing I can think of against,a laced valley(thats what we call them also)is.......they can be effed up when someone invariably,walks on it.This was way worse back in the day of real thin cheapchit shingles.

Its also somewhat dependant on roof's pitch.On a flatter pitch the angle of "repose" in the valley is a less included angle.And the fact that you can easily walk up a low pitch.As the pitch approaches 9 or so 12....that angle or crotch makes it a little more difficult to get the shingle bent,to snug sheathing.This pitch is also where you see guys walkin up valleys,as its easier than goin straight up roof.

Just sayin......they(laced)are pretty.

When I was pricing out shingles, if you wanted them delivered to the roof you had to buy different ones that were $5 or so a bundle higher, plus a delivery fee. It was going to be $750 or so higher to do that. A neighbor brought his skid loader over and it was done. I could not believe how much you burn through shingles when you are laying them down so definitely buy the 10-20% more. You don't want to run out and have to wait for a new shipment to come in when your roof is exposed.

Spend the time to figure out if you have enough venting, both ridge and soffit. I had to change mine to fit the spec that is out there and don't get the ice dams that I used to get in my gutters.

Don't know if anyone touched on this or not but to estimate without measuring you can count shingles, ACROSS each tab is 1' and count UP each one is 6" (divide total by 2)and do the math from there. L x W = sq ft. 1 more thing a skidsteer picking up a whole pallet of roof shingles is gonna be top heavy as a SOB when you pick it up high!!!

Need to bump this thread. My brother and I are planning to reroof the shed at my mothers house. The plywood sheathing needs to be replaced in certain areas. What is the nominal thickness of plywood used for the sheathing. I plan to pick up the materials on the way up there. Original shed is around 40 years old ( gambrel roof style) and is 12x10 and I figure 3 sheets total

It's mainly the top two sections with bad wood and we are planning to just remove the entire piece and replace instead of cutting out certain portions. We know from looking at the underside they need replaced and I am planning for a ridge vent also.

Thanks in advance

typical in your area is probably 1/2". You should verify that. Peel back the shingles near the eave. 5/8" is required in some high snow load areas and I've seen 7/16", although I doubt that is to code.

I here those a lot im used to it lol . I agree not hard caring up either down diff story . 5 gal buckets of rubber roof glue ***** to take up and down ladder .

Try 5 gallon buckets of hot tar (thankfully not full, maybe 3 gallons in them). I did two summers of flat roofing in my youth and hauling tar and gravel basically defined my summer afternoons (mornings were tear-off of the old roof). I only had to haul the tar on small jobs, on big ones the tar was hoisted or pumped to the roof.

Finn,
Thanks for the response. Waiting for the weather to break, which is not gonna happen tonight. They are call for 2-8 inches of snow here tonight thru Monday afternoon.

Probably next month when our 2 schedules line up for 1-2 days.
