You don t need to get a professional in to apply rolled roofing to your house or shed you can do it yourself. Although many metal roof systems can be applied over an existing roof layovers are more commonly done with asphalt shingles. But you must take care to install shingles correctly so they lie flat. The problem with this is that as the metal heats up and expands or cools down and contracts it moves a little on the roof.

There are three systems including glue down torch down and peel and stick. Installing new roof shingles over old effectively doubles the weight of the roofing so you have to make sure your roof structure can handle the extra load. Some people think that they can just install the metal roofing right over the old shingles roof without any barrier in between but this is highly not recommended. First re roofing is allowed in most jurisdictions.

Chances are your roof structure was designed for a dead load of one layer of shingles plus extra for snow and a safety margin. If conditions are right new shingles laid over old shingles can be just as attractive and durable as shingles laid on bare sheathing. If you don t want to do a complete tear off of your existing shingles you have to consider a number of factors.
