Roofs can be a headache and difficult to locate the origin of leaks and points of possible leaks.


Be Caution of Hail roof SCAMS

We have extensive experience with all types of roofs and types of installations of materials

Leaking roofs, poor drainage, and clogged gutters and downspouts can lead to significant water damage inside your home. This is why it is important to get an accurate roof inspection report regularly, both for the inside and outside of the roofing structure.

Outside Roof Inspection

It is very simple to inspect a roof from the outside as long as you have a good unobstructed viewing point on the rooftop. The following checklist of problem warning signs will help you look for any potential problems during an outside roof repair inspection report.

1. Blistered, curled or split shingles
2. Loose or missing shingles or tiles
3. Loose nails
4. Exposed nails (can lead to leaks in the roof)
5. Dark patches on asphalt shingles and/or large amounts of granules in the rain gutters (granular coating is wearing away)
6. Sagging on the ridges or in the center of the roof
7. Broken or loose shingles at the ridgelines and hip lines
8. Rusty or corroded metal (flashing) and loose shingles in the valleys, plumbing vents or near chimneys (it may be necessary to remove excess debris and leaves to inspect thoroughly)
9. Rusty metal or loose shingles where vertical sides of the house meet the roof
10. Overflowing gutters or excess water pooling near the foundation of the house
11. Blisters, depressions near vent pipes, separations in flashing, and clogged drains on flat roofs (pop blisters with a knife and coat them with roofing cement to prevent further damage; depressions can also be filled with roofing cement).

Indoor Roof Inspection

The following checklist includes all the problem warning signs to look for during an indoor roof inspection:

1. Sagging decking between the rafters (if the decking is sagging or deteriorating, the decking will also need to be replaced during a roof replacement)
2. Outside light seen through the roof (this may not be a problem on shake roofs since they tend to swell and prevent leaks during the wet months)
3. Signs of leaking in the attic (dark spots in the wood, especially around vents, chimneys, and other holes to the roof)
4. If dark spots are still wet or soft they are a current problem, if dry and hard it is most likely an old problem that has been fixed
5. Signs of water damage or leaking (usually in the form of water stains, or sagging ceilings due to an active leak or condensation from poor roof ventilation).



Wood shingle roofs

Slate shingle roofs

Gas vent stacks sitting at an angle can cause them to leak.

Your professional inspector thoroughly examines the interior of the structure as well as  at roof level, This skylight was missed by another inspection company. We caught it and brought it to our client’s attention.

Wood shingle roof

This roof is an overlay roof with 3 layers. The roof structure was sagging and had cracked rafters and purlin braces. The buyer had no idea of the problems and these conditions had been overlooked by another inspector and roofer.

Is the air duct causing condensation or is the roof leaking? We can tell the difference.

We examined the attic area and the roof directly above this area and we were able to determine that a soil stack boot at roof level was not sealed, causing this ongoing ceiling damage.

Composition shingle roof

Your inspector evaluates the roofing material and flashing. Just because the roof has been this way for 10 years it sill should be repaired if the flashing has been installed improperly. The transition flashing is installed on top of the shingles.

Cement tile roof

Cement tile roof have their own problems, should be examined closely row by row.

We check all rain shields and flashing carefully.

The rain shield diverter at the gas vent stack is slightly raised from where it should be at the top of the flange base of the stack boot, is leaking and has been for a long time.

Aluminum shingle roofs

We do more than just look at the roof.
