Q: Is a roof replacement just shingles?

• <div><p>A roof replacement will usually include removal of your old roof, shingle replacement, and a new roof underlayment, but it may only include adding new shingles if you&rsquo;re <a href="https://www.angi.com/articles/problems-with-two-layer-shingles.htm">layering new shingles over the old shingles</a>. If you have signs of roof leaks or your roofer finds water damage to the roof decking underneath your old roof, it can also include replacement of the OSB or plywood decking that lays over your rafters and supports the roofing material above. </p></div>

Q: What happens if roof tiles fall off?

• <div><p>Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage. </p></div>

Q: What happens if you don’t stagger shingles?

• <div><p>Asphalt shingles have varying thicknesses across the length, so failing to stagger shingles from one row to the next will leave you with bulges and bumps if the thicker sections stack on top of each other. Not only is this unappealing, but it increases the risk of water intrusion. Stagger each new row by 6 inches to avoid this issue.</p></div>

Q: What questions should I ask a roofing contractor?

• <div><p>Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.</p></div>

Q: Is it more inexpensive to build or buy roof trusses?

• <div><p>If you&rsquo;re building the roof trusses yourself, which isn&rsquo;t recommended, it will be more affordable than buying pre-built trusses. Trusses cost more because they use the same amount of material, but you&rsquo;ll also be paying for the labor, as well as the delivery to your home. However, if you&rsquo;re having a contractor build the roof for you, then trusses will be less expensive, as the labor <a href="https://www.angi.com/articles/roof-framing-cost.htm">costs to build roof framing</a> on-site will cost more. </p></div>

It was horrible. They removed the shingles from the garage and part of the house, we had a downpour, over 1" of water in the garage and down through the attic upstairs and into the main floor. The owner was never on the job. Only a group of college students ages. The owner wouldn't come...

Roofing questions, answered by experts

A roof replacement will usually include removal of your old roof, shingle replacement, and a new roof underlayment, but it may only include adding new shingles if you’re layering new shingles over the old shingles. If you have signs of roof leaks or your roofer finds water damage to the roof decking underneath your old roof, it can also include replacement of the OSB or plywood decking that lays over your rafters and supports the roofing material above.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage.

Asphalt shingles have varying thicknesses across the length, so failing to stagger shingles from one row to the next will leave you with bulges and bumps if the thicker sections stack on top of each other. Not only is this unappealing, but it increases the risk of water intrusion. Stagger each new row by 6 inches to avoid this issue.

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.

If you’re building the roof trusses yourself, which isn’t recommended, it will be more affordable than buying pre-built trusses. Trusses cost more because they use the same amount of material, but you’ll also be paying for the labor, as well as the delivery to your home. However, if you’re having a contractor build the roof for you, then trusses will be less expensive, as the labor costs to build roof framing on-site will cost more.
