Think your roof might be damaged but aren’t sure what to look for? You aren’t alone–diagnosing roofing issues can be tricky, but luckily, there are a handful of telltale signs.

REI Roofing is here to help you determine the source of damage to your roof and how to solve it. If you are in the Holbrook, MA, area and are looking for a professional opinion on your roof, get in touch with us today!

Signs to Look For

Ceiling Stains

Water stains on your ceiling can be a sign of a much larger issue. This likely means that your roof has a leak that, if left untreated for too long, could escalate into problems with mold, rotting frames, and severe roof damage. If you notice ceiling stains, it’s better to call a professional (contact us) right away.

Damaged Shingles

Damaged shingles aren’t just unappealing to look at; they can signify problems with your roof down the road. If you see any shingles that are cracked, curling, buckling, or don’t lay flat, this is almost a sure sign that your roof will leak.

Shingle replacement is a relatively easy fix. At REI Roofing, we offer a plethora of roofing services, including repairs and maintenance. Take a look at our website to discover all we can do for you!


Do you notice your ceiling sagging or drooping from the inside? Or, if you walk across your roof, do you feel a slight bounce when you move? This is another sign of damage. These symptoms could mean that your roof has weakened over time from excess moisture.

Mold or Moss Growth

Any mold or moss growth is a sign of trapped moisture. Mold can be dangerous to your respiratory health, and if it is left too long, your family could be in danger. This trapped moisture can also lead to leaks or further water damage in your home. Most often, growth of mold, moss, or fungi appears in the soffits of your roof or on the exterior of your home where the roof and walls meet.

Rusty Gutters

Rust spots on your gutters are another source of moisture leaks. When a gutter rusts, it can expand and contract, which allows moisture to travel through easily. As with other leaks, this can lead to major damage down the road if not treated properly.

Noticeable Shiners

A shiner is a stray nail that sticks out of the roof because it missed the framing member. These nails are clearly visible and out of place, and they collect moisture and frost on a cold night. When the frost melts during the day, the moisture drips and can cause a leak if the cycle lasts too long. The good news is that there is an easy fix: if you see a shiner sticking out, you can simply clip the nail with pliers.

Roof Vent Issues

Your roof vent is another good place to check for damage. If your vent is made of plastic, you might see cracks, or if it’s made of metal, you might see broken seams. You can also check for missing or loose nails around the seams. Either way, this isn’t always an easy fix on your own. It’s better to be safe than sorry, so if you notice damage that you aren’t sure you can fix, call a professional.
