Roof renovation requires some careful consideration how to go about it. Therefore, the first step is to assess the condition of your current roof properly. Is your roof leaks, you need to take urgent action to avoid damage. But also assess if a new roof with insulation is worth the investment to make your home more energy efficient.
First things first: do you need to renovate your roof?
Start with a closer look from the outside. Visually identify damage to your roof. No need to climb on the roof, but take a quality picture with your smartphone and zoom in. That is an easy way to identify cracks, holes and missing or aged shingles. Also, have a look for moist spots on your walls under the eaves.
On the inside, you will usually notice damage to the roof due to water infiltration. If you have an attic, check for wet spots on the floor of your attic. Often, the areas prone to infiltrations are the connecting parts of your roof, so also check for moist spots around your chimney, roof windows, eaves and gutters. Last but not least, check if any water damage is caused by blocked gutters or drainpipes e.g. by Autumn leaves. Or sediment, plants or lichen on your roof can also cause the water to infiltrate your roof, rather than flowing down the slopes of your roof. In that case, cleaning would be recommended.
Other considerations for renovating your roof
An important consideration is energy efficiency. Up to 25% of heat loss in badly insulated houses goes through the roof, so insulating your roof can make a big difference on your energy bill. An energy audit will show you the potential annual gain.
Protection and prevention is another element to think about. If your roof is getting old, you might want to renovate it before you start having leaks. This could be the ideal moment to upgrade your roof to the latest standards i.e. regarding fire-safety, storm resistance, insulation etc.
And of course, aesthetics are part of the equation. You probably want your home to look good too. With a cleverly designed roof renovation, you can give your house a fresh look and feel.
