Landis Slate Project Makes the Papers
The Landis Slate Roof Project we're working on in Rochester made the front page of the Rochester Sentinal on April 20, 2009.
This project was previously discussed here.
Water Conservation
Water conservation is not a huge issue in our area, but we’re hearing about it more and more on a national level. California Governer Scharzeneggar declared a goal of a 20 percent reduction in water use state-wide by 2012. California currently purchases water from Arizona, but with the continual development expansion in Arizona, particularly in arid areas such as Pheonix, the need for fresh water is a growing issue in the Southwest. How does that affect us in Northern Indiana?

The letter should be on the letterhead of a civil engineering firm and should be signed by a civil engineer licensed in the State of Indiana. The letter should include their P.E. stamp certifying the statements in the letter.
-
The letter should certify that they have inspected the existing system and that it has been adequately cleaned and is working as designed.
-
They letter should certify that they have reviewed the original design and agree with the assumptions made.
-
The letter should state those assumptions, i.e., What was the design storm intensity (10 yr, 25 yr, 100 yr…)? Was the original design to cover the entire site or only changes made during the project? What was the design life of the system and maintenance schedule? Are the soils adequate for the system? Will cleaning the system make it meet the design standards or will additional remedial work be required?
-
The letter should then certify that the existing system was overdesigned with adequate capacity for the changes in the Time of Concentration and the additional impervious surface included in this project.
This letter and the completion of any remedial work required should be completed before a Certificate of Occupancy is issued.
I believe that they have been given adequate notice of the requirements and this should not be a problem for them, even if the remedial work is extensive or additional drywells are required. If for some reason, this becomes impossible to complete before the building is needed for school activities, then a temporary Certificate of Occupancy could be issued. I would not see a problem bonding this project over to the next year if for some reason funds are not available. That would protect the Town’s interests and allow the School additional time to secure funding. Since the project came in well under budget, I don’t see this as a major issue for them.
Slate Roof
Home on Pontiac Street in Rochester, IN
We are currently working on a project to replace a slate roof on a turn of the century home in Rochester, IN. It has the original slate on it, though it has been patched in places over the years. We have been surprised at just how badly the existing slate has deteriorated. We had anticipated taking the slate off shingle by shingle with some breakage, but what we’ve ended up with are pieces not much greater than a couple of inches in diameter and the rest even smaller if not out right disintegrating into a fine powder. It would appear that a good hail storm would have removed most of this slate without our having to touch it!
Deteriorating flashings around turret
Another thing of interest we have found is that the fasteners and flashings are galvanized in lieu of copper. We were aware that the cap flashings were not copper, but we had anticipated the other flashing to be copper. That would have been the standard for the era. Instead, the flashings are fairly thin galvanized sheets, generally cut into small pieces. The nails are gavanized cut nails. The cut nails have held up well, but most of the flashings have deteriorated and begun to rust where they have been exposed to the elements.
The turret in the picture above has slate in reasonable condition, so it was determined to leave this portion of the roof untouched. The cutting of the individual slate pieces with the constant changes in size as the turret reduces in diameter would have been extremely time consuming – probably taking nearly as long as half the rest of the roof. You can see some of the existing flashings around the base of the turret. Where these flashings are deteriorating, we will installed galvanized step flashings that we can slip under the existing starting course of slate.

The slate is being removed using a Slate Ripper. This is a versatile tool that slides up under the slate and is used to rip through the nails. It has sharp hooks to accomplish this and is designed to actually cut through copper nails. With the galvanized nails, it has generally pulled them out. This tool is used during slate installation to repair slate pieces that get broken in the process. It can also be used on completed roofs to help replace damaged slate shingles. The process is similar to when you remove the nails during demolition. The Ripper also works as pry bar to lift the shingles when you slide the replacement into place.
Installation of slate is not a quick process. On this roof we are installing random width slate in two different colors using a 70%-30% mix of purple and green. This further complicates the installation, but should make for a great look! I will post more pictures here or on our website when this project is completed.
A Garden Court for Culver
I was asked to write an article for the Culver Citizen explaining a little about Garden Court and the positive reasons for bringing one to Culver as well as the obstacles preventing the project. It was printed in the paper last week along with a sidebar I wrote giving a little description of the umbrella group that is Garden Court. I have copied the article and sidebar below:
