Leading San Dimas Roofing Company

Concerned about your San Dimas home or business’ roofing?  A great roof isn’t just about keeping things dry and protected from water damage.  It’s also about the perfect balance of appearance, cost, and lifetime.  It improves residential and commercial selling value, and can even reduce cooling loads and insurance premiums.  But above all, a great roof is all about quality materials and workmanship.  We’re a Southern California roofing contractor serving San Dimas with complete re-roofing and new roof installation services.

Re-Roofing Service

Most types of roofs have an expected lifespan, and all can be damaged by wind, hail and other impacts, earthquakes, and fire.  As damage accumulates they reach a point where it’s more economical (and far less risky) to replace the roof rather than continuing to repair leaks.

Our re-roofing specialists know their job inside and out, and you’ll receive certifications on all residential roofing.  They’ll carefully assess your current conditions and perform any necessary structural engineering for the type of roof you’ve selected.  We’ll also take care of San Dimas permits.  As necessary, our pro roofers remove existing roofing materials and replace any bad decking or other damaged wood before installing new shingles, tiles, or coatings along with accessories such as flashing.

New Construction

We’re also a San Dimas roofing contractor of choice for new construction.  We’re always up to date latest techniques and products and are always happy to advise on the type of roofing material and complimentary styles.


We welcome the opportunity to advise you concerning the many types materials, profiles, colors, and profiles available for today’s long life span roofing products.  The products we install have been tested for durability, including seismic, hail, and fire resistance.

Clay Tile

A centuries-old favorite in San Dimas, clay tile is long-lasting and eco-friendly.  Boral US Tile is one of the leading manufacturers, know for high-performance products in a wide range of styles and color.  That includes their Mission, ProShake, and ProSlate lines for a variety of realistic looks.

Composition Shingles

The industry has come a long way since the asphalt composition shingles a generation ago.  Today’s products are lighter as well as more fire and damage resistant.  And they have a much longer life span.  Owens Corning introduced glass fibers for fire and moisture resistance, and GAF Materials Corporation is now the largest manufacturer of commercial and residential roofing materials.

Concrete Tile

Concrete tile also offers extreme durability together with a wide variety of styles ranging from traditional to bold and modern.  Boral Concrete Tile is the oldest and most experienced in the United States, and Auburn Tile is well known for it’s old-world-look products simulating natural beauty.

Hot Mop

For commercial buildings we offer hot mop cap sheet and hot mop rock roofing for a low lifetime cost that meets Title 24 requirements.  Best choices of manufacturers include APOC known for its extensive R&D since the 1960s and Tropical Roofing, also with over 50 years in the business.
