Although metal roofing initially costs more than other types of roofs, it will last longer than asphalt and can provide significant savings in the long term. However, you need to know how to install metal roofing correctly to avoid certain roofing problems. For example, you must install flashing around vents, chimneys, and valleys to prevent water from damaging the roofing system. When properly installed, metal roofing can last for decades.
How to Install Metal Roofing
You will need shingles, nails, and flashing to install a metal roof. There are several types of metal roofing from which you can choose. Recycled steel or copper panels are not only cheap, but they also give you more contours than a shingle. An aluminum interlocking shingle is easier to install and offers better protection for your roof.
For an easy installation, consider purchasing your metal roofing materials from a registered dealer. In addition, buy shingles or metals from reputable companies who can also advise you whether it is possible to install them over your old roof. Prevent leakage by securing the starter flashing to the roof with adhering strips and nails hammered into the fascia trim board and roof sections. Finally, to improve drainage, install a roofing system with hidden gutter channels.
Tips & Warnings
Non-steel metal roofs rust. Therefore, buy zinc- or aluminum-coated metal roofing. In addition, safety is of the utmost importance when installing metal roofing. Protect yourself with rubber-soled shoes and use a non-slip or braced ladder when installing metal roofing. Finally, consider hiring a licensed and insured contractor to simplify the process.
How to Install Metal Roofing Over Shingles
Despite being an alternative to shingles, you can only install a metal roof over a roof with four layers of shingles or less.
- Make a slat board base on top of the shingles. From the bottom upwards, lay 1-by-4 inch pine boards lengthwise two feet apart on your roof, and then use 3-inch wood screws to attach the boards in each corner.
- Install your metal edging around the roof perimeter, and nail them to the roof with 1 1/4-inch roofing nails spaced four to six inches apart.
- From the top downwards, install metal roofing sheets one at a time, and attach them to the wood slat board base with 1/4-inch metal wood screws.
- Space the screws two feet apart, but add more at the center of your first metal sheet. Overlap your next sheet with the first one and continue the pattern with the rest.
- Install 5/16-inch lap screws four feet apart on all overlapping joints of the metal sheets.
- Use 1/4-inch metal wood screws spaced two feet apart to install your metal trim along the roof’s edge and the top ridge. Use notching scissors in the middle of the metal sheets to bend them over the ridge.
- Finally, push self-adhesive closures into openings to prevent water and animals from getting into the roof.
