123 Roofing FAQs: 

What happens if it rains while getting a new roof?

Roofers won’t install a new roof in the rain. The integrity of the new roof may be compromised by rainwater during installation, endangering both your home and the roofing team.

Whether a few drops of rain or an unexpected downpour start to fall, your roofers will be prepared. To prevent damage, they will be equipped with materials to cover any exposed roof sections as quickly as possible. Thankfully, your exposed roof decking is typically made of treated wood to resist moisture, so a few drops of rain are unlikely to cause damage. But, if the wood gets wet, it must completely dry before work can continue.

What is the difference between re-roofing and roof replacement?

A second layer of shingles is added over your existing ones during re-roofing to improve the aesthetic of your roof and provide an additional layer of protection to stop leaks from getting into your home. A roof replacement involves removing your old shingles and installing new roofing materials.

Is it cheaper to re-roof or replace the roof?

The quickest and most cost-effective way to improve the appearance of your roof is to re-roof it. This option is significantly less expensive because it doesn’t require as much time, labour, or supplies. However, it will not allow roofers to repair any unexpected damage beneath the first layer of shingles.

Is it OK to double-layer the roof?

Certainly, if the circumstances are appropriate. Re-roofing is the quickest and most affordable way to enhance the aesthetic of your roof. Up to two layers of shingles may be present on your roof. However, a roof still covered by a warranty may need to be removed to comply with the warranty’s regulations. Make sure you review your warranty first.
