Menifee & Riverside County Asphalt Shingles
Asphalt shingle is one of the most common roofs on Southern California homes, in Menifee and the cities around it.
How We Do It
Tear-offs and re-roofs in architectural shingle
A shingle re-roof starts with a tear-off. We take the old roof down to the deck, replace any boards that are soft or rotted, and lay new underlayment. Then the shingles go on with new flashing, vents and ridge cap.
The two jobs on this page used GAF Timberline HDZ and CertainTeed shingles. You can see the bundles and the underlayment in the photos.

Signs To Watch For
When A Shingle Roof Needs Work
-
Granules In The Gutters
Shingles are coated in mineral granules that shield them from the sun. An aging roof sheds them, so the gutters fill with grit while the shingles wear bare.
-
Curled Or Cracked Shingles
Shingles that curl at the edges or crack across have dried out. Wind gets under them, and water follows.
-
Missing Shingles
A shingle blown off in a storm leaves the underlayment open to sun and rain. Replace it before the next rain finds the gap.
Permits & Title 24
Shingles And The Cool Roof Rule
In Climate Zone 10, which covers Menifee and the cities around it, a shingle re-roof that replaces more than half the roof must use shingles rated by the Cool Roof Rating Council, with an aged solar reflectance of at least 0.20 and a thermal emittance of at least 0.75, or an SRI of at least 16.
An unrated shingle is assumed to reflect just 0.08, so it can't meet that on its own. The rule doesn't apply when an exception does, such as R-38 ceiling insulation, a qualifying radiant barrier in the attic, or no ducts in the attic.

Do you tear off the old shingles?
Yes. A shingle re-roof starts with a tear-off down to the deck, so we can see the deck and replace any soft or rotted boards before the new underlayment and shingles go on.
