What We Look For on Your Roof
Before we apply Roof Shield, we inspect the roof and identify anything that should be repaired, cleaned or addressed first.
Not every roof is a good candidate, and not every homeowner wants to scroll through a lot of photos. So below we show what we check first, and if you want to see examples, you can click each section to open the photos.
If something needs repair first, we tell you.
Our goal is to help you understand what we see before any Roof Shield work is recommended. If the roof needs a repair first, or if it is too far gone for rejuvenation, we will say so.
Everyone can see what we do before a Roof Shield job.
You do not have to open every photo section if you do not want to. The list below shows the main items we evaluate on a roof before treatment.
Pipe boots & penetrations
We check the boots around plumbing vents and other penetrations for cracks, separation, deterioration and possible water-entry points.
Loose, damaged or missing shingles
We look for shingles that are loose, torn, missing, sliding, or poorly repaired so those areas can be addressed before Roof Shield is applied.
Granule loss & wear
Granules protect the shingle surface. We check for excessive wear, thin spots and areas where shingles may be too far gone.
Moss, algae & black streaks
Moss, lichen, debris and dark streaking can show moisture retention, shade issues and areas that may need attention before treatment.
Flashing, valleys & roof transitions
We pay attention to valleys, roof-to-wall areas, chimneys, vent flashing and other places that commonly handle a lot of water.
Popped nails & previous repairs
We look for raised fasteners, old patch areas, mismatched shingles and anything else that suggests repairs should be made first.
Example roof conditions we look for
Click each section below to open example photos. These are sample conditions from roof evaluations and are meant to show the types of things we inspect before recommending Roof Shield.
Pipe boots & roof penetrations
One of the most common things we check. Vent-pipe boots often crack or separate as they age.

Loose, damaged or missing shingles
We look for shingles that are loose, torn, missing, sliding, or poorly repaired before Roof Shield is applied.
Missing or damaged shingles do not automatically mean the entire roof cannot be treated. We identify these areas so the needed repairs can be made first and the roof is properly protected before Roof Shield is applied.
Granule loss & worn shingles
Granules protect the asphalt below. When too many granules are gone, the shingles may be too far deteriorated for Roof Shield treatment.

The two photos below are examples of roofs that have lost too much of their protective granule surface and are too far gone for us to treat with Roof Shield. We see this type of wear often during roof evaluations, which is why we check granule loss closely before every application.
Moss, algae, black streaks & organic buildup
Shade, tree cover and trapped moisture can show up as moss growth, debris retention and dark streaking.

These conditions do not always mean a roof is disqualified, but they are part of the full picture we evaluate before treatment.
Other items we inspect before a Roof Shield job
There is more to a roof evaluation than just one or two photos.

Other items we inspect before a Roof Shield job
There is more to a roof evaluation than just one or two photos.
- Popped nails and exposed fasteners: places where water may be able to enter.
- Flashing and valleys: areas that move the most water and deserve extra attention.
- Previous repairs: mismatched shingles, patching and older repair spots.
- Loose or unsealed shingles: edges or tabs that may be more vulnerable to wind.
- Overall roof suitability: we consider the full condition of the roof before recommending any treatment.
If you want, we can keep adding more example photos to this page over time.
Two roofs the same age can be in very different condition.
Things that can help a roof age better
Good installation, proper ventilation, reasonable sun exposure, regular maintenance and quick attention to small repairs can all affect how a roof performs over time.
Things that can age a roof faster
Heavy tree cover, trapped moisture, poor ventilation, storm damage, installation problems, long-term organic growth and neglected repairs can shorten useful roof life.
We explain what we found and what makes sense next.
Good Roof Shield candidate
If the roof is suitable, we can discuss any prep work needed, the Roof Shield application and the 5-year transferable warranty.
Repairs should come first
If repairs make sense first, we point them out before treatment instead of ignoring them.
Too far gone
If rejuvenation no longer makes sense for the roof condition, we tell you that honestly.
You get a clearer picture
The evaluation helps you understand the visible condition of your roof and why we recommend the next step.
Safety: These examples are educational. Homeowners should not climb onto a roof to inspect it themselves. BlueWater Renew’s evaluation is focused on visible roof condition and Roof Shield suitability; hidden or structural conditions may require additional investigation.
