December 8th, 2008

Monday morning, bright and early and cold! Installing the new perimeter flashing and screwing down the brackets and clamps etc..

Re-installed the aluminum flashing on the "front" roof's north side, this was removed to enable us to get under the old flashing. For some reason the old flashing was left on, this created a couple of problems. The biggest problem was the use of "tar" as a sealant, "tar" has no flexibilty and once it has "hardened" it cracks wide open. There are a number of "caulking" compounds that have up to 400% stretchability, simply put it means that the elasticity will allow extensive expansion and contraction due to heat and cold weather conditions.

Screws were used to ensure that overlapping joints were securely fastened.

All work is now complete and tomorrow is cleanup day.
