This information has been accumulated through my experiences as a product representative for metal roofing manufacturers. During that time, I have done significant research using the internet, conversations with 100s of roofing contractors of all sorts, and first-hand accounts of successful and failure with metal roofing systems.
Steel roof shingles are the most durable and can last about 70 years or more. They are however heavy. In olden day copper was also one among the metal Massachusetts window contractor materials. Copper is very expensive and hence steel and aluminum became the most popular metal roofing materials.
Reality; Modern metal roofs are built to withstand years of abuse from severe weather such as hail, extreme winds, and snow. Hail will not dent a metal roof, and extremely high winds are not a threat either, as many modern metal roofing systems are rated for 120mph winds. In fact, metal roofs perform extremely well in the hurricane. It is not unusual to see the metal roof with no damage, next to naked regular roofs that have lost all its shingles and plywood in hurricane.
Do the roofing contractors have referrals? Do you know anyone who has used their services previously? Referrals are important in order to get an idea of their workmanship and reputation.
The installation information that is on the shingle wrappers is also available on the manufacturers’ websites in downloadable PDF format. Just search the website for whatever brand of shingles you are using. The installation instructions are often found in the contractor area of the site. It’s a good idea to print them out, so you can read it over and get any questions that you have answered BEFORE starting to shingle.
Metal roofing prices usually include all that is needed to install the whole system. Included in the package would be the panels, caps, fastening clips, and all the trims and flashings. But then again, some manufacturers don’t add these to the total cost. And so to be sure, try to ask all about it before making a purchase.
I’m just messing around with a roofing contractors, I hope you had fun reading this article, even though it doesn’t apply to every roofing company and for the most part, most roofing companies that have been around, for over 20 years, seem to be responsible and provide excellent service to their customers.
