[DIY] Re: Sunroom Roof

 

(My experience) is that (usually) roof leaks are caused by poor/ improper installation/ repair methods; (few/ small percentage due to old age/ deterioration).  You have now exceeded the limits on the benefits of metal, but also destroyed benefits by using improper repair methods, IMHO.

1) Where exposed screws are used, (e.g. corrugated), it seems to me to be improper to put the screws in the lower part of the corrugated WHERE THE WATER WILL FLOW and seal depends 100% on the rubber washer.  But I have seen this in standing seam also....(probably for wind resistance?)  I FAIL to understand, but (I believe) the rubber washer will fail just like it does on a faucet or garden hose connection when it gets old/ brittle, especially if over-driven or under-driven (i.e. installation error);

2) You bought the place with this in place, and not something you installed... I understand... and needed to repair, but suspect you (should have) called a BBB approved vendor to do proper repairs by (hopefully) skilled, experienced craftsmen.  I guarantee they would not have used the methods that you did..

I once bought a house with porch roof (shed type) running into main roof, (then 6-yr old when leaked) and found 2-4-inches wide x 20-ft of bare plywood where the metal step-flashing had never been installed.  Now tell me HOW that went 6-yrs without ever leaking? LOL
