It's All About Building

If you'll be getting new metal roofing soon, there are a few things you may want to know about the installation process. Your roofer will know proper installation procedures, and the roofer will explain what you should expect. Still, it's helpful to know a few things so you can make the right decisions and so you're aware of mistakes that might lead to roof leaking. Here are some details about a metal roof installation.

You'll Need To Follow Local Building Codes

Locations vary when it comes to building codes. For instance, homes in hurricane-prone areas might have stricter codes than homes where the weather doesn't get as strong. One of the first things your roofer will do before starting your metal roof installation is to obtain a permit.

Part of the permit process is an inspection from your city. This ensures the roof is put on according to local codes so your home has the best protection. Things like the type of fasteners used and their spacing may be regulated, and a local roofer will be familiar with the requirements and adhere to them so the job passes inspection.

Installation Technique Varies For Metal Roofing

The process for your metal roof installation will vary according to whether you leave old asphalt shingles on or if you start with a bare deck. If the deck is bare, the roofer can screw the roofing to the deck. If shingles are present, the roofer has to add furring strips to elevate the metal panels from the shingles.

You'll need to decide if you want to leave your old roofing in place. While metal panels can be put over old shingles, it may not be the best decision to do so. The roofer might cover up water damage on the roof, and that could shorten the life of your metal roofing. By tearing off the old roofing, your contractor has the chance to inspect the deck and replace any areas that have water damage.

Application Of Screws Takes Skill

Metal roofing panels are installed with screws that have rubber or neoprene washers under them. It's important to apply the right pressure on the screws when installing them. The screw needs to be firm against the washer, but if it's screwed down too tightly, the washer might be damaged, and that could lead to a roof leak. An important aspect of a metal roof installation is driving in the panel screws so they're not too loose or too tight.

Your Roofer Can Order Custom Panels

Metal roofing can be supplied in stock sizes, or your roofer can have the panels custom made for your home to fit the length of your roof. Custom panels are worth considering since you might eliminate some seams and because your roof might have a better appearance with custom metal panels. Your roofer may discuss this option with you if you have room in your budget for the extra cost.
