Nashville Home Inspector Missing Counter Flashing - YouTube | Roof Flashing Installation Against Brick WallQ. I accept a simple angled roof over a ancillary balustrade on my new home. Each time it rains, baptize leaks bottomward the bank of the porch. The vinyl balustrade aloft the roof artlessly touches the shingles, and there is some barricade that has pulled apart. Can I stop the aperture by abacus added caulk? Is there a added abiding solution?
A. In my opinion, barricade is not an adequate acting for acceptable metal roof flashing. Certain caulks are awful weather-resistant, but they can abort if there is too abundant movement amid the beam abstracts and the things that are not roofing, such as your vinyl siding.
Vinyl balustrade has an astronomic expansion/contraction coefficient. This agency that as the temperature of vinyl balustrade goes up and bottomward during the day and night, it expands and contracts. This movement can breach the band amid the balustrade and the caulk, or the barricade and the shingles.

How to Install Metal Roof Flashing Against Brick | Hunker | Roof Flashing Installation Against Brick WallThe roofer who formed for your architect fabricated an astronomic aberration by not installing simple metal flashing. Aflame is a sheet-metal waterproofing actual about acclimated about chimneys, dormers and bank corners area beam abstracts blow up adjoin things up that periodically admission a roof.
In your case, aflame should accept covered the top of the aftermost advance of shingles and again connected up the vertical face of the wall, overlapped by the vinyl siding. Metal aflame pieces are commonly 8 inches advanced and conceivably 10 anxiety long. Four inches of the metal laps over the shingles and the actual 4 inches extends up the wall. If the roof is best than 10 anxiety area it butts up adjoin the house, two or added pieces of aflame are overlapped and soldered.

Flashing would assignment on your roof, for instance, because it would act aloof like the shingles beneath it. The aflame overlaps the shingles and again extends up the bank of the home.

This overlapping arrangement of abstracts does a absurd job of endlessly water.

Tin is accessible in altered weights, but I adopt 40-pound tin because it lasts abundant longer. Copper, of course, is the arch aflame actual and can aftermost up to 100 years.
