Mistake #1 : Purchasing for the Sake of Price
This is a mistake many people make! They avoid metal roofs all together because it is more expensive upfront, but they end up having to redo the work performed not long after. If you live by the ocean, an aluminum roof could be the right long term solution for you. If you live in an area with a colder climate, with winters seeing heavy snow fall, make sure to keep that in mind when purchasing your metals. 1st Coast Metal Roofing Supply can answer any question you have and make sure you are getting the best materials for your home.
Mistake #2: Too Much Sealant
If you think you can waterproof your metal roof by adding a thick layer of gawk on it, think again. If your aluminum panels are trimmed correctly, they will keep the water out. A sealant should be a secondary means of waterproofing your roof, not the main way to avoid leeks. Always put the sealant UNDER the panels, away from light and weather, to ensure it lasts long.
Mistake #3: Lapping the Panel Incorrectly
We do not recommend you install a metal roof on your own. You go to a doctor when you need a checkup, a lawyer when you need legal counseling, and the same should go for building. If you do have a construction background and know what you are doing- remember to put down the larger lip down first. It has an extra piece of metal, where the shorter piece of metal will cover.
