The Best Roofers in the San Gabriel Valley CA Are the Ones Proven Safe To Hire 

 

The state of California requires roofers in the San Gabriel Valley CA to have a license from the state, such as the C39 license for roofing. The C14 license specifically for metal roofing contractors has been repealed and metal roofing is now done under the C39 roofing license which includes roofs using metal, asphaltum, pitch, tar, flet, glass fabric, flax, shakes, shingles, slate or any other roofing materials.

But the state license is no guarantee that any particular roofing company in the San Gabriel Valley CA is doing business honestly, delivering value, or satisfying their customers.

This makes it all the more significant that all contractors for roofing in the San Gabriel Valley CA who bear The Prime Buyer's Report-TOP 10 symbol have been cleared by our research staff as passing all the requirements for Prime Buyer's Report-TOP 10 status such as survey phone calls to previous customers to verify high satisfaction, good complaint record, verified state license, verified liability and workers comp insurance for your protection, only employees legal to work in the U.S., and more.

Roofing Contractors in the San Gabriel Valley CA Perform Numerous Services

Roofing contractors install new roofs, but their experience with certain tasks and materials can vary. for instance, pitched roofs require a greater level of skill to install or repair. Most roofing companies in the San Gabriel Valley also perform regular roof maintenance or roof repairs, including foam recoats and shake roof conversions. Some roofing contractors in the San Gabriel Valley do emergency roofing repairs in the event of a roof leak, often with 24 hour availability.

In addition to installation and roof repair for roof coatings and coverings, some roofers install downspouts and gutters (even seamless gutters). Some of the best roofing contractors in the San Gabriel Valley use manufacturer certified technicians to install, repair or refurbish your roof, so you can expect a greater level of workmanship and better manufacturer warranties on their work.


Roofing Contractors in the San Gabriel Valley Offer Many Parts and Roofing Materials

There is such a wide variety of roofing materials and styles and each roofing material has its own benefits. Choices include shake roofs or imitation shake roofs, wood shingle roofs, cedar shingle roofs, clay tile roofs, slate roofs or even concrete tile roofs.

There are roofing companies in Pasadena, Pomona, El Monte and West Covina who specialize in metal roofs. They can fix or recoat steel roofing, steel roof shingles, stone coated steel roofing, aluminum roofing, insulated aluminum roofing, corrugated metal roofing, copper roofing, or zinc roofing. Some local roofing contractors can  rejuvenate an aging roof and take preventative measures to avoid future roof problems. They might use adhesive methods or modified bitumen to lay down new fire resistant roofing, or may apply elastomeric coatings or polyurethane foam for protection against the elements. In addition to basic roof coverings, some roofing contractors apply hot tar, tar and gravel, or install custom roof edging.

There are also some new products available for the eco-minded homeowner. Instead of wooden roof shingles, roofers might substitute composite roofing or energy efficient roofing. Some roofers in the San Gabriel Valley even have access to ventilation products to insert into your preexisting roof. 

 

ROOF TYPES

There are three main roof types based on their slope or pitch: High Slope, Low Slope, and Flat.

High Slope Roof: Over five inches of vertical rise for every 12 horizontal inches
Low Slope Roof: Two inches to five inches of vertical rise for every 12 horizontal inches
Flat Roof: Less than two inches vertical rise for every 12 horizontal inches

 

ROOF COMPONENTS

The components of a roofing system are: Structural Support, Roof Sheathing, Underlayment, Flashing, and Roofing Material.

Structural Support: Rafters, trusses or joists that support the roofing system.

Roof Sheathing: What immediately covers the structural support. This is most commonly plywood or OSB (Oriented Strand Board).

Underlayment: A moisture barrier immediately on top of the roof sheathing. Sometimes called roof felt.

Flashing: Where the roof surface meets vertical surfaces (like a chimney) or at valleys created where adjoining roof sections of different angles meet, a metallic flashing is installed.

Roofing Material: The topmost layer of the roof which you can see, such as shingles, tile, etc.

 

ROOFING MATERIALS

Asphalt Shingles, or alternatively, Fiberlass Shingles

Rolled Roofing / Built Up Roofing: Used for flat roofs or very low slope roofs.

Foam Roofing / Polyurethane Roofing: Used for flat roofs as an alternative to Rolled Roofing or Built Up Roofing

Metal Roofing

Wood Shakes

Tar & Gravel

Reflective Lightweight Rocks

Clay Tile / Concrete Tile

 

Ice and Water Shields for Roofing
A roofing ice and water shield looks very similar to the traditional felt paper used to line roofs but is higher performance.  Felt paper stops most leaks where water gets under the tiles or shingles but sometimes still lets leaks form by letting water through where one sheet of felt paper overlaps another or where nails have created holes in the felt paper.

The ice and water shield roofing material is made of a rubberized asphalt with a sticky backing that seals overlaps unlike felt paper, and forms a seal around nails when it is penetrated.  Roofers in the San Gabriel Valley can cover your entire roof with the ice and water shield, or apply it only where leaks frequently happen.  The roofing contractors can also bend the ice and water shield to create a leak-proof barrier around anything that penetrates a roof, such as vents, chimneys, and skylights, then use standard roof flashings to cover the ice and water shield sub-flashing.

Questions To Ask Roofing Companies in the San Gabriel Valley 

When choosing which roofer to hire, ask the right questions about their experience, range of services, credentials, and methods and materials before deciding.


• How long have they been in business as roofers in the San Gabriel Valley? This indicates how well they know the local city ordinances, codes, and permit requirements for your area.


• How many roofs have they done specifically in the San Gabriel Valley? This indicates how well they know the performance of different materials and installation methods in your particular climate, rainfall and wind patterns.

• How many roofs have they done of the same type as yours, i.e. same materials: clay tile versus asphalt shingle, same type: flat versus high slope, and same scope: repair only versus tear-off and reroof versus new roofing, etc.

• Can the roofing company give you client names and numbers you can call as references? (All roofing contractors bearing the Prime Buyer's Report—TOP 10 symbol have already had their client references called by research staff at The Prime Buyer's Report so you don't have to.)

• What is the projected time frame for completion of the new roof installation or roof repair?

• Does the roofing contractor have active workers' compensation and general liability insurance for your protection? (All roofers in the San Gabriel Valley bearing the Prime Buyer's Report—TOP 10 symbol have already had their proof of insurance verified by our research staff so you don't have to.)

• How will the roofing companies calculate pricing for new roofs or roof repairs?

• Will they provide a written estimate that specifices the exact amount of material to be used, including sizes, brand names, product numbers etc? (This is key because the cheapest roofing companies often only seem cheaper because they are quoting inferior materials or low quality brands compared to other roofers.)

• Will the roofing contractors provide a written contract?

• Can the roofing contractor prove that all their workers sent to your property are legally allowed to work in the U.S.? (All roofing companies in the San Gabriel Valley bearing The Prime Buyer's Report—TOP 10 symbol have already signed an agreement to only hire documented workers.)    

• How often and when do they clean up?

• What is the manufacturer's warranty on the roofing system or material the contractor is suggesting?


• What kind of warranties and guarantees on their labor do they offer besides the manufacturer warranty on the roofing materials?

• Do they offer multiple types of roofing materials and brands, or are they restricted to quoting one manufacturer?

 

When you've chosen the best roofing company in the San Gabriel Valley for your specific needs and priorities, make sure they are licensed with a C39 license for roofing contractors in the San Gabriel Valley CA. (All roofing companies in the San Gabriel Valley bearing the Prime Buyer's Report—TOP 10 symbol have already had their license verified by our research staff so you don't have to.)
