Alot of houses up here are now being done with it.
Same thing around here Robert. Although all of the newer stuff that I have come across lately appear to have been installed with the correct drainage flashings. See attachment.
Watch for poorly installed or bent (ice damaged) kickout diverters on the roof. A great deal of them are not functioning as intended.
The senator appeared to have dropped the ball by not having the house routinely checked as recommended (especially when abnormal anomalies were observed). You’re not going to get rid of this stuff that’s already out there. Maybe she should propose a bill requiring periodic inspections of synthetic stucco!
This condition can exist with any type of siding material if deficiencies exist in window and door openings, inadequate gutter design and maintenance, roofing leaks etc.
The fact that synthetic stucco is extremely water resistant means that it will keep water in as well as keep water out. So the better siding you have, the greater the potential for these conditions to occur. Simple visual observation around windows and doors, overflowing/back flowing gutter systems that require maintenance, roofs that are missing shingles can prevent most of these occurrences.
The new Energy Star building standards are encroaching upon these same concerns. The tighter you build the house, the better your installation practices must be. It seems that general run of the mill contractors do not keep up with the installation procedures and install new materials in the old way. Inadequate flashing around window and door openings which generally should be installed on any siding application have been neglected for many years. They are out of sight and cannot be readily inspected. Along comes a new siding material and failure to incorporate proper installation procedures results in moisture encapsulation.
This is an example in point.
This is a thermal scan of an Energy Star house taken during an 81° cloudy day at 9:30 a.m. in the morning. There was a short rain shower just prior to my arrival and the moisture had evaporated from the exterior of the roof.
The roofing shingles have already reached 125°F! What’s going to happen when the sun comes out?
This house complies with the Energy Star standard which is superseding existing building standards.
The shingle manufacturer stated they will warrant the shingles for manufacturer defects regardless of an adequate roofing ventilation but will not warrant the shingles if there are indications of heat damage!
The client has been advised and accepts conditions as a cost associated with improved energy savings.
