Hi, I hope I can provide some insight and help. First, as a storm restoration contractor the insurance company does not usually supply enough materials to get the job done to meet building code, and they are not very responsive when trying to get a supplement, so I can understand why it is taking so long. It happens to me all the time. It is not code to put ice and water on the ridges, if that is what you mean by peaks, and I don't think it is in the valleys in MO, but you could call your local building inspector and just ask. Your shingles should have been installed on a day or two when the temps reached 40 or above as recommended by the manufacturer. With that being said, some of the biggest contractors in town still install them with temps well below that. To me that is a sign of contractor that does not care about quality. If the nails are exposed on the nail line of the shingle they were not installed correctly. Also, when the temps are below 40 the shingles become very brittle, so I'm sure they ripped due to handling in those temps. Those can be replaced very easily if there aren't to many of them. The area of concern is going to be water intrusion. However, I wouldn't worry to much about it on your first year of a new roof. You should be ok, but you need to make sure your issues are resolved.
Any damage to drip edge, fascia, soffit, etc. is also a very easy fix. If they do not fix these any of these items I would highly recommend filing a complaint with the BBB. In the St. Louis, MO area you can call Signature Roofing (573-424-4591) and they will take care of you. He has been trained by Haag Engineering to identify issues with asphalt shingles.
I'm from Wisconsin and we have a program called Focus on Energy which implements the ENERGY STAR program for improving energy efficiency of older homes. I'm not sure what you have in your region, but I specifically recommend starting with an expert company that can do a blower door test on your home and use an infrared camera to detect where you have air leakage and heat loss.
The number one cause of heat loss is air leakage. So insulation alone will not solve that problem. Leaky ring joists in the basement where the walls, floor, and foundation meet are one culprit... there is generally lots of inward air leakage here. And in the attic, there are a bunch of sources of air leakage, where warm air wants to rise and escape up and out. (So by the way, ice dams on the roof are not solved by adding more attic ventilation; rather they are solved by first doing air sealing, and second verifying or improving insulation.)
If you intend to DIY this, you can still hire a consultant to do the pre-testing and post-testing, and you might even be eligible for some financial incentives. If you hire a professional company to do it, the cost can be reduced by those incentives.
If you won't hire a pro, then here's a few rules of thumb:
1) Remove fiberglass insulation from ring joists, and either use spray foam or rigid foam to insuate the ring joist, use spray foam to seal the rigid foam in place, minimum 2" thick and you can always fit the fiberglass insulation back in place again when complete.
2) Spray foam over top of wall plates in the attic.
3) Put a gasked on your attic hatch. If you have an attic ladder, buy a specific air sealing enclosure to prevent air leakage through it.
4) Find out if your recessed can lights are IC (Insulation Contact) rated or not. They will be labeled if they are. Build a sealed box around them allowing air space for heat build-up, and consider converting to LED lights so that there is less heat generated. If not IC rated, use cault to seal them to the drywall or plaster, and to close up the holes in the lights themselves.
That's a primer on things... there is more to be done, but these can help!
I would recommend starting with making sure all the existing windows and securely closed and locked. I find windows partly open because they have been painted that way. Take some time to make sure each window closes properly add weather stripping as needed.
Add wather stripping to all doors
check that all the heating ducts are connected securely
The best thing you could do for your home to keep the warm in and the cold out is to 1st. check your insulation in your attic if your not properly insulated the heat will escape. Another is making sure your windows are secured and latched. and proper weather seal is on your doors so draft cannot come in.
Solar shingles are expensive and unproven. I recommend Sun Power photo voltaic solar. An average home is $20,000 to $30,000 and the return on investment is 4 to 6 years on a 25 plus year system.
Well according to Elon Musk yes they are but I'm not sure you can get hold of teslas new shingles or get a price on them yet. But if you haven't checked them out, check out the YouTube video on tesla's new roofing
Let's hear it for Elon Musk and his efforts to move the solar industry forward! Solar shingles have lots of potential. Hopefully, Tesla and Solar City will get it right. We used solar shingles about 15 years ago when installing a new roof and encountered some issues: 1) They were expensive! I would recommend getting a quote for both traditional PV panels versus the shingles and see what pencils out. The cost of PV has come down significantly in the last couple of years. Once you get the quote, be sure and compare the cost/efficiency/performance ratios of the two systems. 2) Maintenance can be an issue. There are more electrical connections with a roof shingle system vs a traditional PV system. More things to create potential problems. The shingles are typically installed in "strings" - where mulitple shingles work together in units. If one shingle has a problem, the entire string "goes down". Check to see how Solar City addressses this issue: can you easily identify where the bad shingle is and be able to replace it easily? Otherwise the efficiency of your system is compromised significantly. Another maintenance issue is keeping all the shingles clean. There is more work to wash down an entire roof periodically to remove dirt buildup than there is for a traditional PV system. 3) Availability: Is Tesla/Solar City providing the units in Atlanta? It may take them some time to gear up their distribution and train people to install them properly. Both important things to consider.
All that being said, it certainly makes sense to have your roof generate power for you! Regardless of whether you go the traditional PV system or shingles route. Best of luck!
