At the point when home or building proprietors are in the market for another rooftop, one of the principal addresses they ask is “Do I have to remove my old rooftop, or can I simply rooftop over it?” It can be a troublesome inquiry to answer on the grounds that while it is conceivable to rooftop over a solitary existing layer of shingles, it is consistently a superior plan to detach the old shingles and introduce a totally new rooftop.

As of recently 2000, it was lawful to introduce up to 3 layers of shingles on a solitary rooftop. Nonetheless, Utah’s construction standards changed, and now the construction standards permit just two material layers on a solitary rooftop.

It is effortlessly expected that the more layers you have on a rooftop, the more insurance you have, however that isn’t actually obvious. It is in every case better to detach the whole rooftop: the underlayment, the shingles, and the flashings.

To begin with, has your rooftop been spilling? Odds are that the underlayment (a waterproof material introduced simply under your shingles) is spilling. The underlayment is significant on the grounds that it can keep water out in any event, when your shingles don’t. On the off chance that your rooftop is spilling, you should detach your current rooftop and introduce another one with the underlayment done accurately.

Another factor is the state of your present shingles. It is safe to say that they are laying level on your rooftop? On the off chance that the shingles are twisting or rough, it would be hard for the new shingles to set down appropriately and in this manner the sealer strip (a piece of tar that seals the shingles down) won’t hold the shingles together in blustery conditions. At the point when this occurs, the shingles will be inclined to brushing off in patches with moderate breezes, after quite a long time after year. This could bring about the rooftop’s life being enormously lessened.

In the occasion you have two layers, it is critical to maintain a strategic distance from the impulse to remove the top layer and go over the base layer. Beside the way this is against Utah’s Uniform Building Code, you won’t have a smooth surface to go over with the top layer. In the event that you can envision all the nails from the top layer that are abandoned, you can imagine the issues that happen when nails are beat down, or pulled. In any case, the black-top shingles in the base layer get pretty bit up!

At the point when another rooftop is put on any structure, it is ideal to supplant the flashings too. Flashings help the shingles seal to the channels, dividers and other rooftop infiltrations in zones that release frequently. During a re-rooftop it is basic for the material contractual worker to seal to the old flashings. Now and again, these old flashings are not as solid as new ones would be, and they detach, messing up the structure proprietor.

Basically, the most ideal choice while reroofing, is to evacuate the principal layer and begin once again. The star’s are:

The rooftop deck (generally pressed wood or 1x supports) can be reviewed for harmed wood that should be traded for quality just as giving the new rooftop framework’s nails a lot of holding power.

You can ensure the underlayment is done effectively, giving the rooftop a more drawn out life.

The shingles will seal down accurately, permitting the sealer strip to hold the shingles together during ends up to 110 miles for each hour.
