How To Choose a Roofing Company

Roof installation is a large home improvement project that can cost a significant amount. It’s crucial to do your research and find the top-rated company for the job. Here are some important considerations for selecting a roofer.

• Experience and credentials: Companies operating for over a decade demonstrate years of experience on top of expert service and happy clients. Only consider companies that are properly licensed, bonded, and insured. Inquire about professional certifications, such as those from the National Roofing Contractors Association.
• References and reviews: Research companies carefully by checking reviews on sites like Google, Yelp, or the Better Business Bureau (BBB). Look for years of consistently good feedback. You can also request recent local references.
• Detailed written estimate: Quality roofers will provide a thorough written proposal. The proposal should specify the full scope of the project, materials required, and full price with no surprise charges. Avoid providers that offer unclear quotes, or ones that seem way too low or high.
• Roofing materials and products: Quality roofing companies sell quality materials that can handle Rockville's weather and last a long time. Be careful of contractors pushing extremely inexpensive or generic options. Check out shingle samples before committing.
• Responsiveness and communication: Your contractor should keep you regularly updated throughout, from the estimate to project completion. A representative should answer questions promptly and resolve any concerns while working.
• Warranties and guarantees: A reliable roofer will provide robust manufacturer warranties that cover shingles for 30+ years along with at least a 5-year guarantee on workmanship. Be wary of shorter guarantees.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it protects your home in important ways. Be aware of these common signals that your roof needs to be evaluated and repaired by a professional roofer.

Roof Age

Your roof's age and material are key factors. Asphalt shingles, the most common residential roofing material, generally last 20–25 years before needing replacement. Have your roof evaluated if it’s nearing or past this lifespan to determine if it needs to be replaced.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof issue is leaking. Stains on insulation, ceilings, and walls — or in your attic — usually mean that water is seeping through deteriorating shingles. Don't ignore small leaks, because even these can encourage mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

If you can see your roof decking or sheathing material underneath your shingles, it means those shingles are severely curling or losing their seal and need to be replaced. Shingles should lie flat to prevent water from entering your home.

Cracked, Broken, or Missing Shingles

Carefully examine your shingles from the ground or a safely-placed ladder. Look for any shingles that are cracked or have lost their protective granule coating. Over time, environmental factors like storms can cause surface damage. To keep your roof in good condition, we recommend replacing any missing shingles or ones with gaps.

Flashing Deterioration Around Roof Penetrations

Metal flashing on your roof creates a watertight barrier around valleys, vents, chimneys, and other areas where water can leak in. If the flashing is becoming damaged, loose, or worn down, it may leak. Promptly address any flashing issues.

Sagging Roof Line

A structural problem can cause your roof to exhibit noticeable sagging or unevenness in slope. If you notice signs of the roof sagging, schedule a professional inspection. An unsupported roof deck will continue to deteriorate over time.
