CHanging roof pitch over poarch ?


Greetings--

Small older house, pier and beam that's no longer level.

Back porch and laundry room have flat roof-- that's of course now leaking. It currently has rolled roofing on it. Water tends to puddle at the joint, as the house "tilts" that direction slightly.

The main roof needs to be replaced. Its going to have to be torn off to the rafters and plywood decking added. Its currently 1 layer of wood shake shingles and two asphalt shingle layers.

QUESTION-- since the main roof is going down to the rafters, could I have additional rafters added to change the pitch of the flat portion to a "normal" roof ? Looking at it this seems a good replacement for the forever troublesome flat roof.

Comments ?

You could do it whether or not you were removing everything to the rafters.

OK-- so is rebuilding the roof a perfered method-- or is covering the flat portions with a "rubber" type of membrane ?

The difference in the quotes is about $1k more for the job that suggested the membrane fix.

Just depends on what you want. If you like having the roof flat, then it should have membrane roofing, yes. If you want it pitched, it's not a difficult job to add rafters and pitch it.

Also, you use the term "rebuilding". What I would personally do would be more like "adding to". There's no reason to remove any of the old roof unless it's in the way of adding the new. Even then, you only need to cut back enough to attach the new rafters to the ceiling joists or the front beam, whichever applies.

The existing sloped roof needs replacing. Its at least 25 yrs old.

Some of the shingles have been damaged by wind, limbs ect. Its not leaking yet, but it will be soon. The roof vents' flashing all need to be replaced a well.

QUESTION-- Is there a perfered pitch ? The existing roof is a steep pitch until it goes flat.

One contractor planned on using 10 ft joists from the edge of the flat roof into the existing roof, resulting in whatever pitch that gives.

I'll try this on this post, cause I don't have time to make an all out drawing right now. But he's talking about:

.................................................. ....+
................................................+
.........................................+
..................................+
...........................+
....................+............This area
.............+
......+
+__________________________________

Side view. The line is your existing roof, the +'s are the new roof.

This should be framed in and sided.

CHanging roof pitch over poarch ?


I obtained another bid--this time w/o modifying the pitch of the roof.
This contrator said he would guarentee the workmanship for 5 yrs on the roof and 2 yrs on the flat portions.

His bid said they would use "x # squares of torch down" on the flat portions.

Can someone enlighten me as to exactly what this is ?

I'm still concerned that water which pools up at the joint between the sloped and flat portions will cause a leak.

Comments ?
