Roof ventilation is very important. Ensure that the intake from the eaves is adequate and not blocked in the attic with insulation. Ensure you have adequate exhausting on the ridges. Proper ventilation can extend the life of your roof. If you have any questions, you should consult with a roofing professional in your area.
Proper ventilation is extremely important for a long lasting roof. If you roof is sweating and creating condenstaion it can deteriorate your entire roofing system from the decking and supports to the underlayment and shingles. Also, depending on your climate, inproper ventilation will contribute to ice dams. I'd recommend cutting in a roof long ridge vent as soon as possible.
Ventalation is one of the most important parts of your roofing system. Has proper intake air flow coming in from the eaves of your home, where your gutters are located, and exausting through the ridge of your home. All roofing manufactors require this as part of there warranty information because it does not only affect the condisation in your attic space but will also weaken your shingles and lower there live span. If your home already has proper insolation and proper ventatation another option would be to add a power fan unit on your roof near the ridge with a humidistat built it. This will turn on automatically at whatever tempature you set and also when moisture builds but will turn on. Moisture in the attic space is common in winter months due to cold tempatures outside and heat from your attic space meeting. I would have a roofing company come out and inspect your soffits to make sure they are ventalated and also to ensure you have a ridge vent installed on your home to start.
Although each home is unique in design, it's safe to say that virtually every home should have a properly vented ROOF. A properly insulated home, with a properly vented roof, should not have a condensation problem.
Did you do diligence to see who you were dealing with? Was the roofer licensed or required to be by the state or local unit of governement? ? Was a permit pulled and the job inspected by a building officia/ when completed? If not call your local building official and have them come out to look at the job? The roofer may be in violation of the bullding codes and be subject to disciplinary action by the state. I would check all these things before you proceed with a lawyer. Last if that contractor is not established, he won't have the money to fix it. But if he is insured you may be able to go after his insurance company. So aways ask to see a license, insurance and work comp certificate when dealing with any company and find out how long they have been in business prior to signing any contracts.
Ideally, you will have no sweating if you have proper insulation and ventialtion. Generally moisture forms by ice freezing on the bottom side of the roof sheathng or the nails sticking through tje shething and when it melts you have water( sweating.) Not good. This can lead to wet insulation, mold and deterioration of the sheathing and or framing members. Get itchecked by a professional.
In twenty years it only came up once. It was an old house and the owner knew it was substandard. It is taken for granted by most people that a house was built to code and still in sound condition. It would seem logical then if you put the same riding material on the house everything should be alright. There not enough inclination here to even guess what went wrong but you need to get a licensed, or at least certified inspector, and another reputable roofer to evaluate the installing and structure to determine Weiss at fault.
This is a strange situation. I wonder what type of roofing material was used? It would be very unusual for an asphalt shingle to be too heavy for a roof. So was the roof framing undersized in the first place? Were there existing deficiences which were not corrected, that should have been corrected prior to re-roofing? Indeed, you may need a lawyer to sort this out. Good luck.
Hello Debbie, I would ask how that was determined. I think that fact that the question was brought up in the first place really raises a red flag. In my experience, if there was a question about changing the laod on a structure an engineer should have been consulted. I would ask the contractor to make things right based off the advise of an engineer. Note-If this contractor is a roofer, I would not think that would be a good fit for the repairs.
