Before you install a new roof, there are a few things you should know

If it turns out that your roof will need to be replaced, don’t rush straight to the hardware shop to buy shingles. You can always opt for a service that provides metal roof installation in Malaysia. Since, it is much easier to hire professionals to do the job for you. However, you can do it yourself as well, if you are well-prepared to do so. Before you begin the actual installation, there are a few things to consider.

Choose the Correct Material

Choosing a roofing material is one of the most crucial decisions you’ll make. Consider the appearance, pricing, and longevity of each available product before deciding a material. Asphalt roofing shingles, for example, are one of the most cost-effective solutions, but their longevity is among the lowest for residential roofs. Concrete or metal shingles, on the contrary, typically last longer and are a great choice if you’re looking to make a long-term investment.

Aside from more typical shingles such as asphalt, shakes, and slate, you can also purchase stunning metal roofs that mirror the appearance of other roofing materials, as well as architectural shingles that outperform traditional asphalt in terms of both performance and appearance. While some of these modern materials can cost up to three times as much as traditional 3-tab asphalt shingles, they will last longer and improve the exterior appeal — and thus the resale value — of your home.

If your roof was last replaced two decades ago, don’t only go with the same type as previously; check into new roof kinds as well. Consider each choice carefully and weigh the benefits and drawbacks of each. If you’re not sure which option would be ideal for your home, call a professional to inspect your roof and determine which products would be the great investment.

Decide whether you want to peel it off or layer it on.

Another important option to make is to either remove the old shingles prior to installing the new set, or to just stack them on top of them. You can’t have more than two shingle levels on your roof because it’s against the building code.

Peeling off the old layer of shingles before installing new shingles is recommended because the second level of shingles will place extra stress on your roof. You can apply it over the initial layer if you’re strapped for time or money. Stripping off the initial layer is strongly advised if the old shingles are bending or the roof is uneven. If you reside in an area with strong winds, it’s also a smart idea.

If you reside in a cold region, removing the old roofing allows you to add an ice and water barrier, which is a rubber layer inserted at the roofline that prevents leaks caused by ice formation. Moreover, if your roof is made of a substance other than asphalt, stripping off old roofs becomes more challenging. Removing the roof may need changing the plywood decking as well, which can be pricey.
