Can you put metal roof on flat roof.

Install metal flashing along the edge of the roof using a hammer and 1 2 inch roofing nails. Use metal snips to cut flashing material. Consult the guide for your shingle brand to determine the specific method of installation required to preserve the warranty. Because of the shallow height of the undulating ridges of the 5v and corrugated profiles and the use of exposed metal fasteners to screw the metal to the roof deck they are limited to a slope that will shed rain quickly.

A metal roof can be installed right on top of your existing roof most of the time. Most codes now allow no more than two layers of roofing before requiring a complete tear off. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Flat metal roofs can last for almost 35 years in ideal conditions.

Secure the gutters using a hammer and 1 2 inch roofing nails. Measure the length of the roof edge with a tape measure. Plus it has the added advantage of reflecting heat from the sun which keeps energy costs down. Install gutters in valleys as needed.

Metal specifically aluminum is known for its durability. Codes vary so call your local building department to know how to install metal roofing over shingles properly code wise. So if your roof has two layers it may require a complete tear off even though steel is lighter than asphalt. Metal roofing typically comes in large sheets but you can order smaller sizes to fit around unique features or irregular extensions of your roof for example small patios or covered stairwells.

Cut the gutters to fit using metal snips. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. This eliminates the cost of ripping or tearing off existing material. Low slope metal roofs require less material which reduces the overall load on the building s structure.
