Residential roofs usually don’t need to be overhauled much throughout a homeowner’s life. That’s why most homeowners are not familiar with the roof replacement process. It’s a fairly complex job that involves multiple layers and details, which is why you need to hire an experienced contractor.
What Happens During A Roof Replacement?
1. Regional Climate Analysis
Before deciding on roof replacement, a professional roofing expert needs to assess your roof’s condition and how your local climate affects structures. Part of the planning should focus on the best time of the year to do a roof replacement.
2. Selection of Roofing Materials
- asphalt shingles are a common, affordable option
- wood shingles are a tad more expensive, but add curb appeal
- metal roofing is more complex and has durability
3. Removal of Old Roof
While it’s possible to install new asphalt shingles over old ones, this idea creates extra weight on the structure. It also doesn’t address problems such as bumps and bubbles on existing shingles and can make these defects worse in appearance.
On top of this, if you cover an existing roof with an entirely new roof, you are unable to inspect the integrity of anything under the original roof, like flashing or decking. Without being able to professionally assess these vital elements, you are not eligible to apply a warranty on the new roofing system. While removing an old roof is a little extra work, it’s a more reliable option in the long run.
4. Surface Preparation
Drip edge involves installing metal with a 90-degree angle that prevents rain from seeping through edges. Snowy winter climates require an ice and water shield that blocks moisture from developing, which shortens the lifespan of a roof.
5. Underlayment Installation
The layer between your roof deck and roofing material, like shingles, is called underlayment. This layer is lightweight and adds water-resistant durability to your roof. It blocks water, chemicals, and runoff from leaking into your home.
6. Flashing and Sealant
Flashing involves adding joints with sealant to components where leaks may be possible, or two separate entities meet, such as around chimneys and vents. The more you can keep moisture from seeping into the attic, the more durable your roof will be.
7. Attic Ridge Vents
The final step before job site clean-up is adding ridge vents and rib caps for maximum attic ventilation. Once completed, a final inspection is needed to ensure proper installation.
