Help. The exterior roof line over my garage is sagging from old age. Just had a new roof put on and it did not improve the sag as the roofer said it would. Can I have something done about this without disturbing the new shingles? Any one know? Or have a referral?

EAsy to answer....roof has to be supported from underneath by beefing up existing framing. A 2 ton jack should do the trick. Start in the middle and work outwards jacking the roof from underneath and ad new vertical members as needed. Spacing every 4 feet should do the trick. Use 2X6 lumber..it is more resistent to bowing and stronger for snow loads. Your roofer was full of shee-ite when he said new shingles would elminate sag without additional support structure....especially when if he didn't remove the old shingles and just roofed over the old ones adding more weight and aggravationg the situation....This solution will only work on saggy roofs.....ladies you are on your own with the old boobies..

Shingles weigh anywhere from 235#'s per square to 450#'s per square. (One square is 100 square feet or 10x10) Depending on what style, wind resistance, brand, etc of shingle, the addition of that weight is not going to improve a sagging ridge line. This sounds like there is an issue with the trusses inside the garage framing. It could also include something stupid like old decking that should have been replaced when the roof was. Unfortunately,the nature of shingle roofs does not allow for any sort of easy or cheap fix when having to potentially work where the new product was installed.
The most practical answer that I saw and agree with is to jack and shim the trusses. This should be done by a licensed carpenter, preferably one who has worked with house movers before.... yes, the guys who move the WHOLE house. I would also double check your contract with the roofer and see if that claim was made in writing prior to the work being performed. If it isn't horribly annoying, I would suggest leaving it alone for the time being, but you are correct in that it will need to be addressed at some point. Hope this helps and sorry to hear that!!

If the roofer told you the shingles would improve the sag, he was very wrong. My guess is that it sags along the ridgeline towards the middle. If you are willing to put some posts with a header inside the garage, that would work. You would jack up the header which would jack up the rafters at the same time. Then add your posts with necessary shims and your problem is solved. But before I done that, I would nail a simpson hurricane clip to each rafter and top plate to make sure they do not lift at all.

The probably did not replace the framing. Check if the contract included repairing the framing and support beams. If so call the contractor back to fix it. You may need a legal opinion.

Contact your local better business bureau. Ask them the names of 3 local contractors you can trust for qoutes. Don't just pick the cheapest. Contact your local building inspectors office and mention the 3 names. He can't outright tell you who to pick but if you ask nicely he might mention which one he has had the least trouble with.
