Incorrect Installation of Membrane that caused Water Damage on a flat surface in Knoxville TN

In this photo, you can see that several roofs have been installed on top of the other. This is generally not a good practice for longevity and is prone to leaking. Nails are likely not to reach the wooden decking below; even if they do, I am likely to be driven into some soft areas of wood. Exposing the entire roof deck is always the best plan.

In the photo above, you can see that a flat roof was installed over the porch stoop in the rear of the house. It appears that it was not tied incorrectly to the existing shingles, nor was it tied incorrectly to the house under the eaves. This area appears to have been having problems for a long time as the structure underneath is compromised with rot. 

Here, you can see that the decking boards beneath the shingle layers have given way to rot. Sagging is evident, and the area is very soft and spongy. Some boards will need to be replaced as the roofing process starts.

Here, you can see that the gutters or damaged and aged. These are old-style gutter hung with spikes instead of hidden hangers and the gutter has begun to pull loose from the facia and fall away from the house. These gutters are recommended for replacement. 

No ridge vent and incorrect ridge cap material were discovered during the inspection. Ridge vent allows superheated air to escape from the attic while soffit vents allow cool air to be pulled in from underneath. The ridge on this house has been kept with cut-up architectural shingles.

In this photo, you can see that the installer turned the shingles up the chimney and caulked them to the surface. This is not an acceptable method of flashing a chimney and likely to have many problems.
