How To Choose a Roofing Company

Roof installation is a major home improvement project that can cost tens of thousands of dollars. It’s crucial to do your research and find the most qualified company for the job. Here are the key factors to consider when choosing a roofer.

• Warranties and guarantees: A reliable roofer will provide strong guarantees from the manufacturer which protect shingles for over 30 years along with at least a 5-year guarantee on workmanship. Be wary of shorter warranty periods.
• Detailed written estimate: Quality roofers will provide a thorough written quote. The quote should detail the full project scope, materials needed, and total cost with no surprise charges. Avoid companies that provide unclear bids, or ones that seem way too high or low.
• Roofing materials and products: Reputable roofing companies sell quality materials that can handle Annandale's weather and endure a long time. Be careful of contractors offering extremely low-cost or generic options. Check out shingle samples before committing.
• Experience and credentials: Providers with a decade or more of experience show stability and expertise. Before hiring, verify that a provider has current licenses, bonding, and insurance. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• Responsiveness and communication: Your contractor should communicate consistently throughout, from the quote to the completion of the project. A representative should respond to questions quickly and address any concerns while working.
• References and reviews: Vet companies thoroughly by verifying on review sites such as Google, Yelp, or the Better Business Bureau (BBB) that they have consistently positive feedback. You can also request recent local references to learn more.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it plays a vital role protecting your home. Be aware of these common signals that your roof needs to be inspected and repaired by a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most popular residential roofing material, generally last around 20–25 years before needing replacement. Schedule a professional inspection if your roof is nearing or past this lifespan to determine if full replacement is needed.

Leaks or Water Stains in Your Home

One of the most obvious signs of a roof issue is leaking. Stains on ceilings, insulation, and walls — or in your attic — usually indicate that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can lead to mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

If you can see roof deck boards or sheathing under shingles, it shows that those shingles are severely curling or losing their seal. This means it's time for replacement. Shingles should lie flat to stop water from entering your home.

Cracked, Broken, or Missing Shingles

Carefully inspect your shingles from the ground or a safely-placed ladder. Look for any shingles that have cracked or are missing granules. Over time, environmental factors like storms can cause surface damage. To keep your roof in good repair, we recommend replacing any shingles that are no longer attached properly or that have gaps.

Flashing Deterioration Around Roof Penetrations

Roof flashing creates a barrier against the elements around valleys, vents, chimneys, and other areas that penetrate your roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Any issues with flashing should be addressed promptly.

Sagging Roof Line

A structural problem can lead to noticeable roof sagging or unevenness. If you notice unevenness, schedule a professional inspection. A roof deck that isn't reinforced will only get worse without proper support.
