How to Know When It’s Time for a Full Roof Replacement Inspection
At Njall Construction, one of the most common questions we hear from homeowners is: “Do I need a roof repair, or is it time to replace the whole thing?” While some isolated issues—like a minor leak or a few damaged shingles—can often be handled with a quick repair, there are certain signs that it may be time for a complete roof replacement instead.
Watch for these red flags:
Shingles that are cracked, curling, discolored, or missing
Moss, mold, or algae growth on the roof surface
Bald spots on shingles where the protective granules have worn away
A visibly sagging roofline or drooping areas
Damaged or missing flashing, fascia, or other critical roof components
Water stains on ceilings, persistent leaks, or mold in the attic
Your asphalt shingle roof is over 20 years old (or your roof is showing age based on its material type)
If you’re noticing one or more of these issues, it’s a good idea to schedule a professional roof inspection. Our team at Njall Construction can assess the condition of your current roof and help you decide whether a repair will do the job—or if it’s time to invest in a long-term solution with a brand-new roof.

Our Step-by-Step Roof Replacement Process
At Njall Construction, we don’t just replace roofs—we build lasting protection for your home. Our goal is to make sure your new roof stands strong against the elements, keeps moisture out, and enhances your home’s curb appeal.
We begin every roof replacement by removing all old shingles and materials, right down to the wood decking. From there, we install your new roofing system using a detailed, six-step process that builds durability from the ground up.
Each step is handled with care, precision, and quality materials—so you get a roof that not only looks great but lasts for years to come.
Leak Barrier
Our roofing systems include a water-resistant underlayment designed to provide extra protection against ice dams, driving rain, snow, and other severe weather conditions.
Roof Deck Inspection and Repair
We inspect and repair your roof deck—the sturdy base supporting shingles—to ensure it’s solid, dry, and able to protect against moisture and harsh weather.
Starter Strip Shingles
Starter shingles ensure a uniform look and reliable performance while serving as a protective barrier against wind damage.
50-Year Shingles
Our 50-year shingles provide exceptional durability and long-term protection, serving as your roof’s first defense against moisture, wind, and harsh weather.
Cobra Attic Ventilation
Cobra attic ventilation promotes airflow, helping regulate moisture and temperature levels—boosting energy efficiency and protecting your roof from within.
Ridge Cap Shingles
Ridge cap shingles are installed along roof peaks to seal vulnerable areas, preventing water infiltration and enhancing both protection and appearance.
